First, the installation structure of the present invention will be described with reference to FIGS.

The landscaping surface installation structure according to the present invention is installed on a flat, evenly grounded base surface, the non-woven fabric (1) and the reinforcement is installed on the upper side of the non-woven fabric (1) for absorbing the penetration water and reinforce the soft ground It is constructed in the form of a lattice, the reinforcement lattice (2) bent in the middle portion in accordance with the inclination angle of the construction surface to be constructed, the greening sheet (3) to prevent the landfill material 6 to flow down, and the bent of the reinforcement lattice (2) It is composed of a hook (5) for connecting the upper end and the lower end to prevent the structural reinforcement and bending due to earth pressure, and the reinforcing bar (2) to be maintained without distortion.

1 is an external perspective view of an installation structure of the present invention, in which a nonwoven fabric 1 is positioned at a lower portion thereof, and a reinforcement grating 2 is positioned at an upper side thereof, and a greening sheet 3 is adjacent to the reinforcement grating 2. Located. The new nonwoven fabric 1 is again located on the upper part of the rebar grating 2 and another rebar grating 2 is located on the upper side of the rebar grating 2 and at least one layer is formed in a repeating manner in which another greening sheet 3 is located. Are stacked. The lower end of each steel rebar lattice 2 is bent inward and can be distinguished using this.

This stacking form is determined to have an optimal strength depending on the height of the inclined surface to which the installation structure is applied. Although three layers are shown stacked in the figure, it is obvious that this is for illustration. According to the installation structure of the present invention, the construction can be performed at an inclination angle of 1: 1 to 1: 0.3.

Reinforcing bar grating 2 is composed of a plurality of reinforcing bars spaced apart vertically and horizontally to form a grid. The horizontally connected rebars form a straight line, and the lower side of the vertically connected rebars is horizontally bent toward one side. The reinforcing bars of the bent portion extend inwardly of the normal surface and consequently are located on the upper surface of the nonwoven fabric 1. The detailed coupling structure will be described later with reference to FIG.

The greening sheet 3 is placed inside the reinforcing bar grating 2. The greening sheet 3 prevents the soil from flowing down and helps the germination and growth of grass, woody plants sown on the green vegetation soil 7. It also prevents the fill material 6 from flowing down. Filling material (6) can reduce the material cost by using the general soil produced in the construction as the soil to be filled on the nonwoven fabric (1).

The greening sheet 3 is divided into roughly three parts, one side of which is placed on the horizontally bent inner surface of the reinforcing bar 2, and the middle part of the green sheet is extended to be in close contact with the inclined part of the reinforcing bar 2, The remaining part is located on the surface of another nonwoven fabric 1 located at the top. The detailed structure is also described later with reference to FIG.

Figure 2 is a rear perspective view of the installation structure of Figure 1; As shown, green vegetation (7) is located on the front, the reinforcement grating (2) arranged in the form inclined to the rear is located, connecting the upper end and the lower end of the reinforcement grating (2) forming a layer A plurality of hooks 4 are arranged while inclining. In the figure, the reinforcing bar lattice 2 forms three layers, and the hooks 4 also include three layers. The hook 4 is thus installed at the intersection of the rebar lattice 2 to reinforce the structure and prevent the bending due to earth pressure.

In addition, the pile 5 is embedded in the side of the hook (4). Pile 5 is installed on the lower side of the reinforcing bar (2) serves to prevent the reinforcing bar. For example, the pile 5 may be a 4.5 cm x 4.5 cm x 30 cm (or 30 cm or more) pillar that can easily dig the fill material 6 in the form of a sharply cut end of the material of the untransmitted material. The pile 5 is preferably fixed in close contact with the surface of the reinforcing bar in the direction that the rebar lattice does not move. The greening sheet 3 is also inclined along the inner surface of the rebar grid 2.

3 is a side cross-sectional view of the installation structure, including an enlarged view in which the connection state of the reinforcing bar grating 2 is enlarged. The part shown by the dotted line is nonwoven fabric (1) filled with the fill material (6) thereon, the steel rebar lattice (2) is bent with an inclination, and the greening sheet (3) is also the same as the rebar lattice (2) It can be seen that the shape is bent.

The enlarged part A-1 is a state in which the hook 4 is connected to the upper end of the rebar lattice 2, the end of the hook 4 is bent in a semicircular shape, and the end of the vertically extending rebar of the rebar lattice 2 is also It is also bent at an acute angle, which is the type that can be applied to the uppermost case.

The enlarged part A-2 shows the connection state of the reinforced steel lattice 2 laminated | stacked on the upper part and the lower part, respectively. As shown, the rebar end of the upper rebar lattice 2 is bent horizontally and the lower rebar end is straight. In this state, the overlapping portions are coupled to separate connection pins 2a.

The enlarged part A-3 is a reinforcing bar at the lower end of the reinforcing bar 2, in which the semicircular end of the hook 4 is coupled to the end of the reinforcing bar which is also horizontally bent. The opposite end is part of enlarged A-1.

A side sectional view of a normal surface formed by the installation structure according to the invention is shown in FIG. 4. As shown, the nonwoven fabric 1 is located at the lowermost part, and the reinforcement grating 2 bent at an acute angle is located at the upper part thereof, and the greening sheet 3 is formed along the inner side of the reinforcement grating 2 in the shape of a "c". Is inserted.

In addition, a plurality of hooks 4 are connected between the greening sheets 3 to form triangles with the rebars of the reinforcing bar 2. In such a state, the landfill material 6 recycled soil discharged from the construction site is laid out and firmly compacted by various means. By stacking a plurality of the reinforcement gratings 2 as described above, it is possible to construct the surface while obtaining a desired inclination angle stably up to the required height.

Construction of the facade is carried out in the following steps.

Referring to FIG. 5, after performing the preliminary investigation, the step S1 of flattening, leveling and compacting the ground of the foundation ground, and installing the nonwoven flat on the foundation ground ground in the step S1 (S2) and Step (S3) of installing a reinforcing bar grating, hook, and pile set to the angle of inclination of the non-woven fabric in accordance with the inclination angle of the non-woven fabric, and to assist the germination and growth of vegetation, and to prevent soil from flowing out Step (S4) for installing the sheet, and step (S5) for filling the top of the nonwoven fabric using the fill material (S5), and repeating the above steps (S2-S5) according to the landscaping height of the required surface (S5) S6), and stabilization and greening of the landscaping surface (S7).

First, survey the terrain for the installation of landscape plan, create accurate design drawings, check the foundation ground, check the soil quality, select the number of compaction and select construction machinery and equipment. At this time, clay, clay, etc. are not suitable as fill material and should be avoided. In addition, it is desirable not to use large stones larger than 20 cm and small stones. In addition, the range of 30 to 40cm from the surface is composed of vegetable soil for greening using grass or woody plants.

After the preliminary investigation in consideration of the above points, the ground is solidified by digging, covering, and compacting such as tree root removal, surface soil digging, drainage treatment, and foundation ground clearance. In the process of solidifying the ground, drainage treatment must be carried out. If there is insufficient ground support, reinforcement is required, and the surface must be horizontally and horizontally terminated (S1).

After the pre-irradiation and the ground chopped as described above, the nonwoven fabric 1 is provided as a reinforcing member. That is, after cutting the nonwoven fabric 1 to a predetermined length, it installs horizontally from the reinforcing side to the normal side. In this case, it is preferable that adjacent nonwoven fabrics 1 overlap each other, and at least 10 cm or more overlap. This overlap not only at the position parallel to each other, but also at a position such as a curved surface, so that more parts overlap, especially in parallel (S2). The arrangement of the nonwoven fabric 1 can be changed depending on the form of the surface of the place to be constructed.

After installing the nonwoven fabric 1, the reinforcing steel grating 2 is installed so as to meet the inclination angle. When the inner surface to be constructed, the outer curve is formed to change the installation position of the reinforcement grating (2) according to the terrain to respond flexibly.

After installing the reinforcing bar grating 2, the hook 4 is connected to the upper and lower ends of the rebar grating 2 so as to form a triangle with the reinforcing bar grating in a form that enables the skeleton to be stably viewed from the side. The connection point of the hook 4 is located at the point where the horizontal and vertical rebars intersect.

Upon completion of the hook 4 connection, the rebar grating 2 adjusts its position using stones so that it is well positioned with the normal surface at the time of final completion. At this time, the reinforcing bar grating 2 is preferably connected to be horizontal to the surface of the nonwoven fabric (1). After the installation of the reinforced steel grating 2 is completed, the pile 5 is installed in the designated position (S3).

After the installation of the pile 5 is completed, the greening sheet 3 is installed. Before installing the recording sheet 3, the hook 4, which was installed in the step S3, is temporarily removed for the convenience of installation. After removing the hook 4, the projections (parts where the recording sheet is temporarily covered) of the reinforcing lattice 2 are covered with a vinyl pipe which can prevent the greening sheet 3 from being damaged.

In this state, the greening sheet 3 is installed along the inner side of the rebar lattice 2 and is erected outward through the outer side of the rebar lattice 2, that is, the portion covered with the vinyl pipe. At this time, care should be taken not to misalign the front and back of the recording sheet (3).

When using a vegetation net in special cases, install the vegetation net inside the recording sheet. After installing the recording sheet, connect the hook (4) again (S4). A portion of the greening sheet 3 temporarily placed on the protruding portion of the reinforcing bar grating 2 is folded after the completion of filling the soil to maintain the "c" shape.

After the recording sheet 3 is installed as described above, the compaction process using the fill material is performed. The process of compacting landfill materials first selects and selects the landfill material, and then performs compaction.

In the case of crushing and compacting the fill material (6), at first, about half of the height of the reinforcing bar lattice (2) is filled with soil and compacted using a compact and a vibrating roller. Afterwards, repeat the work of filling up the remaining piece of land with the rest of the pile. For example, if the maximum height of the rebar lattice (2) is 50 cm, at first, fill the soil about 25 cm and fill the soil, and then fill the soil about 25 cm again to complete the fill.

In the process of crushing and selecting the fill material (6), a range of 10 to 20 cm from the surface is drawn by manpower, and the center part uses a machine. This fill process can be changed according to the terrain, the state of the ground, it is desirable to work to obtain the maximum strength (S5).

When the work using the fill material is completed, the above steps (S2-S5) are repeated as many as necessary. In other words, the process is to install one rebar grating (2) and to ground the ground is to repeat the operation of stacking a plurality of rebar lattice (2) to reach the desired height as planned by the initial pre-work.

The repetitive reinforcement grating (2) is to be noted during construction, the order of lamination of the greening sheet (3) and the nonwoven fabric (1), the first non-woven fabric (1) is located at the bottom, but laminated to the greening sheet (3) A part of) will be located (S6).

In addition, the protruding portion of the reinforcing bar grating 2, which is located on the uppermost layer, is bent in a hook shape so as to incline downward from the surface of the ground at a depth of about 200 to 300 m / m. This is shown in FIG. 4.

As described above, after all of the steel rebar lattice are installed, green vegetation work is performed on the surface of the legal surface to stabilize the slope of the landscaping method. Green vegetation is spraying compost and modified soil mixed with grass seed and woody plant seeds about 30 ~ 50mm thick on the surface of legal surface. This vegetation soil and greening method can be achieved using a conventional method.

According to the present invention as described above, since the landscaping method is completed with grass, wood plants, etc., since no traces of the construction have been made to the outside, the natural beauty can be retained as it is, and the soil of construction sites, etc. can be directly used as the soil material. It has an economic effect. In addition, since the work efficiency of the surface formation is high, it is possible to shorten the air, and can cope actively according to the form of the surface, so there is excellent workability.

The present invention does not use concrete walls, retaining walls, shotcrete, rock bolts, etc., to create a slope of the soil and Pungam area where the ground is soft, to preserve the natural landscape, for example, around the road, golf course, mountain, railway It can be used to provide a natural environment in many places such as riverbanks, riverbanks and parks.
