孔112之作業依瓦斯電動鑽孔機工作及安全作業標準施作， 只鑽孔不需攻牙，且通孔112之孔徑以不超過四分之一瓦斯 管管徑為原則。鑽孔時可將密閉式穿孔機，如日本大肯精 密株式會社生產販售之密閉式穿孔機Ν〇·3、電動機Ν〇·8及 13 1240053 配合之特殊I法等f知機具技術，架設於瓦斯管上，以鍵 條圈繞瓦斯管並將穿孔機緊密地固定於瓦斯管上，藉由恭 動機帶動穿孔機之刃部，利用磨㈣方式進行鋼管 作業，鑿孔過程中不會產生火花引爆瓦斯的危險。 10 15 20 參閱圖1及圖7,鑽孔完畢後應立即將上、下鞍座211 、叫裝設於通孔112之位置上，且使其通道218對應於通 孔U2，亚均一性地以螺栓組213將兩鞍座211、212鎖固（ 步驟62)。此時，位於上鞍座211底面上之止茂環體叫將 圈繞於通孔m之外周緣外，並藉由螺检组213《鎖固使其 緊密地頂抵於管壁1U上’防止瓦斯於上鞍座2ιι及管壁 m

5 10 15 20 1240053 、而之間的瓦斯管内進行一水線的拉設，然後再透過水線 的拉引將光纜9施放於瓦斯管内。前者通常是在纜線可沿 瓦斯官線直接連結到客戶端或是只針對某—區段佈纜之情 下採用，而後者則是須於管線的中途穿出，或因多區段 ^ &細工工序上的安排及便利性的考量而予以採行。關 2直接施放的方式，首先是先將鎖固於穿設管411上之無孔 基頭421除去，將預定施放之光纜9依序穿過有孔塞頭 二金屬環形塾片419、密封環體418、金屬環形塾片419及 ㈣環體418，再將光境9穿入穿設管411，使其佈設於瓦 斯管内。光纜9佈設過程中，必須先將二組密封環體418 及環型塾片419依序塞入穿設管411内，並將有孔塞頭· 不鎖緊地連結於穿設管川上，以不使瓦斯外料原則，待 光缓9穿設完成後再將有孔塞頭42〇予以鎖緊。此時，穷 封環體4㈣因受穿設管411轴向之塵力而向穿設管川： 官控方向膨脹，使其緊貼於光繞9之外周面，增加防茂效 果。紐9可於管内沿瓦斯管行進，直達於用戶端。> 參閱圖^圖8及圖9,間接施放的方式中，水線的佈 設方法乃是於進π端之穿設管411上置換成有孔塞頭似， 於出口端之觀測管311上改以設置視窗塞頭313、穿Μ 411上更換為有孔基頭42〇，及f設管4ιι内|設具有

invention relates to a method for fixing # General & Refers to-a method that uses existing ... can be laid under the principle of live gas construction, the route of the ι line and ^ official line method of laying the cable. 、 / 、 【Previous technology】 With the development of science and technology, the concept of sharing multimedia content and resources has become more and more popular. The pressure on the transmission of data has increased. The tradition: the double-line transmission method , Its bandwidth has gradually failed to meet the present: Geren's ". Therefore, a low attenuation, large bandwidth and good electromagnetic transmission medium, light slow, came into being. At present, the layout of the light environment has been extended, long distance Trunks, regional networks, and metropolitan area networks are slowly developing to the client's access network. 'Gj This is expected to become the backbone of the metropolitan transmission network in the future.' 94.05 Amend this optical gauge-like setup for a variety of applications And environment, there are various laying methods of overhead, direct buried, pipeline, underwater and indoor Dai Temple, but it is still best to use the existing transportation facilities and transportation roads, in addition to saving construction costs In addition to shortening the construction period, the most important thing is to be economically competitive. In addition to the oil pipeline and gas pipeline # transmission facilities are not widely used, other existing telecommunications lines and traffic roads have become various companies. Manufacturers must compete. In this situation where there are few paths to deploy, because there are not many competitors, it is easy to cause Φ to break, which will cause users to slaughter #, sheep. In addition, the 1240053 94.05 amendment for the installation When part of the line is used as an overhead line pole, in addition to being easily damaged by external factors such as wind and earthquakes, it also has a visual impact on the environment, and its subsequent use and maintenance are also not easy. Then: For the method of using direct burial, because some of the material contained in the soil may cause damage to the protective layer outside the light winding, the frequency of its repair and replacement must be ancient. In addition to the inconvenience, its relative cost will also increase. And two other things: It is also easy to suffer unexpected damage during excavation. In $ # # 加贝 么 On the other hand, when the light transmission of the fluid transport officer's internal force is set, in order to take into account the safety during construction, 10 15 20 Stopping the flow of fluid during the construction period, in addition to avoiding the peak hours of user use, will also cause customers to be inconvenient and inconvenient. Therefore, if the user's conditions are not affected, Next, the method and installation of hair extension 7: m can be used in fluid pipelines, spears, low-yoke workers, and subsequent maintenance. Besides cost and trouble, it can also ensure data transmission. The problem of wind 4 is waiting. [Summary 1] Therefore, the first object of the present invention is to provide a guide that can be installed on a pipeline under a live gas for the cable to enter and exit.

In the detailed description of the preferred embodiment, it will be clear that in the following description of the preferred embodiment, refer to FIG. 1. Before explaining the example, it must be understood that components with similar functions will be used. The same number. Fig. 2 and Fig. 3, the preferred embodiment of the present invention is a 1240053 94.05 modification of a guide for the entry and exit of the supply line, but the optical cable arrangement of the underground low-pressure gas pipe is used for illustration, but not limited thereto. The guide 2 for cable entry and exit according to the present invention is provided on a low-pressure gas pipe 10 for gas circulation. The low-pressure gas pipe 10 is a metal material and includes a pipe wall 111. The optical cable 9 enters and exits and passes through the through hole 112 of the official wall 111. The guide 2 of the present invention is described by using a saddle device in this embodiment, but it is not limited thereto. The saddle device includes a saddle group 21, and a main arm tube unit 31 and a side arm tube unit 41 connected to one of the saddle groups 21, respectively. 10 15 The saddle group 21 is an upper saddle 211 and a lower saddle 212 sandwiched on the low-pressure gas pipe, and using the bolt set 213 to detachably lock the two saddles 2 and 2i2 to The outer wall of the tube wall lu. The upper and lower saddles 212 and 212 have a concave shape and a concave shape, respectively, and correspond to the shape of the tube wall. The upper saddle body 215 and the lower saddle body 22G, and both ends of the two saddle bodies 215 and 22 () help out. It extends horizontally into two upper screwed sections plus two lower screwed sections 221. To fix it, a bolt 223 is sequentially passed through the upper and lower screw holes 217, 222 of the two screw joint sections 216, 221, and then locked with a nut 224. In this embodiment, the upper saddle body 215 is the base of the most basic type of the guide 2, and the (base) 215 is recessed close to the wall of the pipe to form a bottom surface 215. The = different surface is-the top surface passes through ... Put on the saddle body: between the surface 215G and the bottom surface 2152 and corresponding to the through hole 112, for the border line to enter and exit the through hole 112 of the pipe alcove. The opening end of H ^ 215G is formed on the outer periphery of the open end—the upper surface of the body 215 is 2152 ta, which is an annular groove 219 for _ oak_ μ ° extension, and this groove 219 214, when the saddle group 21 is locked 20 5 10 15 20 1240053 94.05, it is fixed on the pipe wall 111, only the door can be opened, and the vent 脰 214 can provide the saddle group 21 and the pipe wall. The stop function of the engineering team. The operation is to pass through its Hongren Putian Saddle Group 21 and install it in a fluid-free month. The pain on the spring is slightly higher than that of the stop ring ring 21 and it does not affect the basic function of this device. m9 'In the preferred lean embodiment,' the two corresponding and lockable culprits' are used as the components connected to the low-a gas pipe 10, and also some ring-shaped bases, etc. This base can be preset on the tube Force on the wall nl: The position is fixed. The reserved parts, such as the flip type buckle seat or the buckle, etc., can be fixed as long as the base can be fixed on the pipe wall 1 n. In addition, the transport pipelines that can be set up in this device are not limited to F 1, low & gas officials, but also water pipes, electric pipes, thunder equipment pipes, etc., and the pipe's shelter can also be cast iron, PVC, FRP, and mixed temples, and the size of the official path can vary according to actual conditions. "In addition, the upper saddle 211 is provided-the observation tube 31 can provide light environment 9 square, g The poor information entered in the line increases the convenience of deployment. This observation tube is located on the upper surface of the upper «215, which extends vertically upward from the outer periphery of the channel 218 'and is located away from the inner periphery of the upper saddle 211- On the surface-the inside of the main arm of the accumulator 314 may be non-simultaneously corresponding to the external threaded portions 315, 316 of the main body plug 312 and the window plug 313 (see Figure 4). The main body plug 312 is a non-through The plug of the hole is used between the setting of the light seat group 21 and the layout, and can be used to seal the nozzle of the observation tube 311, and the window plug 313 = for waterline and gauge routing. In the process, there is a bolt body 317 penetrating through the center, and a transparent portion 318 provided in the bolt body 317. When the screw body 317 and After the inspector 311 is connected, the outside of the observation tube 311 can be corrected through the transparent part 10 1240053 94.05 to correct the situation where the optical cable 9 in the low-pressure gas tube is installed by Benkawa. The material of the claw of the transparent part: glass, acrylic, etc. When inside the tube When there is no fluid circulation, the main body base 3 12 and the window plug 3 13 can be omitted. As the light _ 9 is -semi-rigid body material f, in order to prevent the seam 9 from being too private during casting, the angle of f fold is too large, resulting in damage. The positive port that affects the transmission of data packets is connected with a penetrating pipe 411 for cable entry and exit. The penetrating pipe 411 extends outward and upward from the bottom end of the outer peripheral surface of the observation pipe 311: in the direction of the axis of the official line At an angle, it is used for the installation of the optical tube 9 and has a side arm female thread portion 413 on the inner peripheral surface far from the gas tube, and has a hole groove 414 and a hole groove located in the center and communicating with the observation tube 311. 414 has a large-aperture portion 415 located above, a small-aperture portion 416 located below, and a shoulder portion 间 located between the large-aperture portion 415 and the small-aperture portion 416. In addition, the airtight Effect, there is no more on the wear pipe 411: ¾ unit 412 The stop & unit 412 has two side arm sealing ring bodies 418 and two metal ring gaskets 419 installed in the through pipe 411, and a perforated plug 42 which can be connected to the through pipe 411. The side arm sealing ring The body 418 and the metal annular gasket 419 are staggered from bottom to top and are placed in the hole groove 414 and abut against the shoulder 417. The holed plug 42 has a holed external threaded portion 422 at one end, which can be screwed It is connected to the internal thread part 413 of the side arm, so that the holed plug 42 and the insertion pipe 411 are connected. When the holed plug 42 is locked, the ring seal body 4 can be squeezed through the metal ring gasket 419 , So that it expands toward the center of the diameter of the pipe 4 丨 丨, so that it is in close contact with the optical cable 9 through the pipe, increasing the anti-leak effect. Furthermore, after the saddle group is erected to the delivery room of the optical cable 9, a non-perforated plug 421 can be connected to the perforating pipe 411 to seal the hole groove 414 to prevent gas from leaking. On the other hand, when 1240053 — π. Repaired the optical cable 9 through the pipe, it can be opened with a hole plug 42, one end of the low-pressure gas officer, and the space between the hole plug 42G and the difficulty is filled with oil, which can prevent The role of gas knitting lubricating domain 9. Here, the angle between the axis of the pipe shaft passing through the tube and the axis of the gas pipe is 45 degrees for description, but this is not the case. In this embodiment, the main body plug 312 and the non-porous plug 421 have the same shape and size, but in different implementations, the two plugs 312 and 421 ° are different helical bodies. In addition, when there is no fluid circulation in the conveying pipe and it does not affect the basic function of 10 15 20, the stopper element 412 and the non-hole plug 421 can be used to save the province. In addition, the main arm official unit 31 is mainly used for In the process of observing the light around the wiring, the information of the light moving in the low-pressure gas pipe due to wiring is obtained. When the main arm tube unit 31 is omitted, the pipe 4U of the side arm tube unit will extend outward and upward from the outer periphery of the channel 218, and the hole 414 communicates with the channel 218. / See Figure 10, in order to ensure that the completed optical cable 9 is installed so that the optical cable 9 exposed in the saddle group is not damaged due to excessive bending caused by external forces, a protection unit 51 can be added between the wearing sigh b 411 and the optical cable 9 . The protection unit η includes a wave & 511 and two cold-shrinkable tubes η respectively set at two ends of the wave tube 511]. The wave tube 511 is sleeved on the penetrating tube 411 and the optical cable 9 exposed on the penetrating tube 4 to prevent the exposed optical cable 9 from being excessively bent and damaged. The cold-shrinking tube 512 close to the through-tube 411 is covered on the through-tube 411 and the wave tube 511. After pulling out the supporting material provided in the cold-shrink tube 512, the cold-shrink tube 512 can be hermetically covered by the through-tube. 々Η and Wave & 5 11 provide the function of anti-leakage on the interface, and away from the cold shrink tube 512 of the pipe 4 ″, for air-tightly covering the wave tube 511 and the optical cable 9. When the optical cable 12 5 10 15 20 1240053 a ^ 94.05 amended this 9 without excessive bending and damage, and in the case of fluid η spirit, the captive 51 can be omitted 'without affecting the basic function of the device. The present invention, the cable " in and out device are drilled on the transport officer of a section and set at the _ π 0a retreat point and the -exit point respectively. The relevant anti-leakage elements are used in the clothes to reduce Bao Xi shake Α π low ^ the internal fluid and the external fluid cause danger. The mechanism f allows the optical cable 9 to move in smoothly under the condition of milk π ^. The cable is installed between the "occupation and exit points" to achieve the purpose of cabling. . Referring to FIG. 5 ′, the method for laying cables in a pipeline according to the present invention is preferably implemented. The main implementation steps shown in FIG. 5 are included to lay the optical cable 9 in both the mouth and the official line. In the present embodiment, the light τ is hypercardia, and see the layout. It is described with a saddle group 21 for the cable to enter and exit, and a low waste gas pipe with gas circulation. But not limited to this. Two things that must be explained before beginning to describe the implementation steps, the preparation of the pre-construction plan, the start of construction, pre-employment labor safety and health training, the excavation and installation of work wells, safety maintenance, and The known procedures and operations such as the placement of manholes and handholes are not important to this method: and the features are not repeated here. Refer to Figure 6. After excavation at the selected site, the saddle group 2! Can be set on the exposed watt tube. Before setting, it is necessary to drill through the wall of the low-pressure gas tube at a certain position. Operation of hole 112 (step 61). The drilling of the through-hole 112 is performed according to the gas electric drilling machine work and safety operation standards. Only drilling does not require tapping, and the hole diameter of the through-hole 112 is based on the principle of not exceeding a quarter of the gas pipe diameter. When drilling, you can set up a closed-type punching machine, such as a special type I method with a closed-type punching machine No. 3 produced by Japan Daiken Precision Co., Ltd. and a motor No. 8 and 13 1240053. On the gas pipe, the key pipe is used to circle the gas pipe and the puncher is tightly fixed on the gas pipe. The blade of the puncher is driven by the respectful motive, and the steel pipe is operated by grinding. Sparks ignite the danger of gas. 10 15 20 Referring to Figure 1 and Figure 7, immediately after drilling, the upper and lower saddles 211 and 211 should be installed at the position of the through hole 112, and its channel 218 corresponds to the through hole U2. Sub-uniformly The two saddles 211 and 212 are fastened with the bolt set 213 (step 62). At this time, the Zhimao ring body located on the bottom surface of the upper saddle 211 is called to be wound around the outer periphery of the through hole m, and it is tightly pressed against the pipe wall 1U by the screw inspection group 213 Prevent gas leakage on the upper saddle 2m and the pipe wall m_. In order to confirm the correctness of the setting of the seat block 21, a three-quarters of a PVC pipe or a small section of light environment can be extended through the through pipe 411, and the relative position of the through hole m and the channel 218 can be checked to check the two Whether the installation position of saddle 2ii '212 is correct, if there is deviation, it should be adjusted or reinstalled. Of course, 4 moxibustions are Wu Xi L Sha ^ Bean Page 421 and Φ Love. ί 1, Tu Zhi and Wang Yue Chou Jishuo 312 are respectively connected to the gates of the penetrating pipe 411 and the observation g 3 11 to prevent gas from being observed by the observation pipe 3H and the penetrating pipe 411 before the light environment 9 is cast. Because the gas tube in this embodiment is a low-pressure tube and the saddle group 21 is placed for a short time, so the amount of gas outside the process of construction is still in line with the requirements of relevant regulations, and no bad Shadow plastic. The light environment 9 can then be cast from the-end of the channel 218 (step 63). The optical cable 9 can be divided into two types: direct and indirect. The direct method is to extend the light 9 directly from the pipe opening f 411 into the 'lay in the gas tube; the indirect method is First, a waterline is installed in the gas tube between the σ end and the 14 5 10 15 20 1240053, and then the optical cable 9 is placed in the gas tube through the water line pull. The former is usually used when the cable can be directly connected to the client along the gas line or only for a certain section of cable, while the latter is required to pass through the pipeline midway or because of multiple sections ^ & Arrangements for convenience and convenience are taken into consideration. The direct release method of Guan 2 is to first remove the non-porous base 421 locked on the installation pipe 411, and pass the planned optical cable 9 through the two metal ring-shaped cymbals 419 and the sealing ring in order. The body 418, the metal ring-shaped cymbal 419, and the ring-shaped body 418, and then the light environment 9 is penetrated into the penetrating pipe 411 so as to be arranged in the gas pipe. During the installation of the optical cable 9, two sets of sealing ring bodies 418 and ring-shaped cymbals 419 must be sequentially inserted into the wearing pipe 411, and the holed plug head must be connected to the wearing pipe without locking. Do not make the gas material principle, after the completion of the installation of the light delay 9 and then the hole plug 42 is locked. At this time, the poorly-sealed ring body 4 向 is exposed to the penetrating pipe by the dust force in the axial direction of the penetrating pipe 411: it expands in the direction of official control to make it close to the outer peripheral surface of the light winding 9 and increase the anti-moisturizing effect. The New 9 can travel along the gas pipe in the pipe and reach the user end directly. > Referring to Figures ^ Figures 8 and 9, in the indirect casting method, the waterline is laid out by replacing the through-pipe 411 on the inlet side with a plug with a hole on the observation tube 311 on the outlet side. Instead, set the window plug 313, wear M 411 to be replaced with a hole base 420, and f set the tube within 4m | set a rope supplement device with a hook. Then use the soap and water head at the setting points of the inlet and outlet] 420 and 313 to ensure safety. Secondly, using FRP material: Second, to prevent gas material < through & strips or a section of optical cable 9 mouth end through the pipe 411 enter 'to the direction of the u-end to move through the pipe 15 1240053 94.05 correction In the 10th industry, the piping strips stand upright and the sleeve 5 has a loop and elastically shrinkable waterline. When the piping strips travel to the exit end from the view of the exit end® base j 13 When the tube 411 is used, the hook of the rope repair device can be used to pick the loop of the waterline and pull the waterline out of the pipe 411 at the exit end. At this time, the waterline intended to be laid is connected to it, and then The inlet pipe 411 draws back the pipe strip and brings out the water line intended to be laid out. After the waterline is pulled out to the required length, a long metal rod is added at the front end so that it can be placed in the dental tube 411 and abut against the shoulder 417 of the penetrating tube. The same method is adopted at the exit end. At this point, the waterline is set up. After the waterline installation is completed, remove the holed plug 420 and the window plug 3 13 on the inlet pipe and the outlet pipe 411 and the observation pipe 3 ι, and change to the non-hole plug 421 and the main body plug 312. Tighten the nozzles of the feed pipe 411 and the observation pipe 311. Leak test with soap and water to ensure safety. 15 20 The receiver then casts the optical cable 9. The cabling work will be carried out using the waterline drawn in the foregoing. First, the optical cable 9 is sequentially passed through the plug 420 'metal ring gasket 419, sealing ring body 418, metal ring gasket 419 and sealing ring body 418' at the entrance end, and a ring with The pull-out net cover 'is followed by loosening the non-porous base 421 connected to the inlet of the t4u at the inlet end, taking out the end of the reserved waterline, connecting the waterline to the ring of the pull-net cover, and The two sets of sealing ring bodies 418 and metal ring gaskets 419 that are sleeved on the drill 9 are placed in the penetrating officer 411, and the holed plugs G are locked to the mouth of the penetrating pipe 411 without locking. The hole plug 42Q is locked on the principle of not letting gas out, then loosen the hole-free plug of the outlet pipe 4m at the outlet end, and take out the other-end of the waterline. Then, start to pull back the waterline from the exit end, and the light line 9 connected to the inlet π end of the waterline will pass through the inlet end through 16 10 15 20 1240053 舛 .05 to modify the 2 pipes and exit the exit end. Thread the tube 411. At this time, remove the pull-net cover / set the sealing ring body 418, the metal ring-shaped cymbal 419, the sealing ring body 418, the Month% gasket 4 丨 9, and the hole plug 42G in order. On the light environment 9, the two sets of sealing ring bodies 418 and metal ring-shaped cymbals placed on the money 9 are placed in the insertion pipe 411 and the hole plug 42 is locked, and the entrance end is worn through the sigh Kawakami's holed plug was also tightened. After completing the entrance and exit ends of the mirror, use soapy water to test whether there is any leakage of the tile f 411 and the hole plug 420. If there is gas or no leakage, the hole plug 42 should be re-locked. Urgent or take other remedial measures. Usually after the light release 9 is released, a part of the light release 9 will be extended from the wear pipe 411 for subsequent other guards or maintenance use. These exposed reserved lines can be accommodated in μ and 彳 m. Therefore, 'this method can be changed Contains-Step 64 of accommodating and protecting the cables exposed to the guide. In order to perform Step 64, you must make some cooperative measures in the process of Step 63: In Step 63, insert the optical cable 9 into the duct 411 Before the metal ring gasket 419 and the sealing ring body 418 are installed on the optical cable 9, the cold-shrink tube 512, the wave tube 511 and the cold-shrink tube 512 must be installed on the light guide 9 in order, and the light After the guide tube 411 is passed through the outlet tube 411 at the exit end, the metal ring gasket 419 and the sealing ring body 418 must be installed on the optical tube 9 and then set. Referring to FIG. 10 and FIG. 11, first, after the installation of the optical cable 9 is completed, a section of the exposed optical cable 9 is reserved at the entrance end and another adjacent exit end for future construction use, or the optical cable 9 is connected to the point box and used. The optical fiber fusion splicer is connected to other clients according to customer requirements and design cores. The reserved optical fiber 9 must be organized and rolled into the optical cable storage rack, and then this 17 5 10 15 20 1240053, 94.05 amended The optical cable 9 is put away for convenience. Secondly, in order to make the connection between the optical cable 9 and the pipe pipe more airtight, and damage caused by the solidity f, and must be handed over: :: 511 to protect the light, € 9 to prevent from passing through the river respectively in the waves The tube 511 ^ shrinks the tube 512, and makes the cold-shrink wave tube 511 and the light environment 9 and: "" tightly attached to the wearing pipe-, after the cold-shrinking operation is completed, it must be directed to :: Probability. When there are no safety concerns, make a quality test—test, and it will surely form the entire process of laying the optical fiber cable 9. In summary, the present invention discloses an E-in and out device and its construction method, regarding the convenience of its optical routing. A „And use an easy method to achieve the purpose of cloth, spring, and do not need to avoid, to meet the convenience of construction. No need to stop the gas during the Taifeng period. In terms of economic benefits, you can easily reach out in your long life, and the materials used are all synthesized without external jaws. Moreover, the cost of construction is not high, which is in line with the economy. ^ Yu + by n / general requirements on the other hand ′ due to not directly buried rate. * This does not affect the H f component, and reduces the replacement and maintenance of the fighters.
