Description

The invention relates to the field of traffic management, and more specifically to devices for protecting hose pipelines, hoses, conduits, engineering pipelines or other communication pipelines (hereinafter referred to as hose pipelines) from damage caused by the passage of vehicles through such pipelines.

The invention can be used to quickly organize a road crossing through the laid temporary sleeve pipelines passing over the carriageway of roads with a hard pavement across the traffic with the protection of these sleeve pipelines from damage caused by the passage of vehicles.

Hose pipes, hoses, conduits, flexible engineering pipelines and other utilities (generally - hose pipes) have many applications, they can be pressurized, carry water, electricity, include a cable to enable signals from remote sensor locations and their use requires access to Maintenance. Often such pipelines must pass through roads subject to vehicular traffic. The protective device for crossing the pipeline must ensure its safety. At the same time, the crossing must reliably perform the function of the road itself, ensuring the accident-free passage of vehicles. The organization of a road crossing through hose pipelines must be efficient, fast and economical.

Various protective coatings are known in the art.

It is known from the prior art that on swampy sections of the route, when crossing natural obstacles, lay roads of various designs are used,

Known track collapsible cover for temporary roads on soft soils [patent RU 2013487 C1, publ. 05/30/1994, IPC E01C 9/08, E01C 5/14], which includes bars placed relative to each other with a gap, united by transverse articulated links to form sections and located along the axis of the route. The bars are provided with additional ties made in the form of hidden oval-shaped free-sliding locks, which are located at the ends of the bars with the possibility of assembling the cover into an accordion. Sections of adjacent tracks are interconnected by telescopic rods.

Known collapsible bearing cover [patent RU 2183701 C1, publ. 06/20/2002, IPC E01C 9/08], consisting of sections, including a frame made of pipes interconnected. The section is made by links, consisting of a row of pipes in the width of the road, forming a bearing coating-flooring, hinged to each other with the possibility of rotation around the longitudinal axis, ensuring their arrangement in rows during decomposition, stacking, loading and transportation.

Such crossings do not serve as a transport road and do not withstand long-term loads from the weight of construction vehicles. They do not have serial production and do not allow you to quickly and efficiently organize a car crossing.

A device for a technological crossing (TP) through main pipelines (RF patent No. 2221954) is known in which the trench with the pipeline laid in it is covered with a bridge, which is created by hanging onto the pipeline laid in the trench of a weighting agent - a polymer-container ballasting device (PCBU) or a group of weighting agents with filling their tanks with soil and backfilling the trench with soil at the site of mounting the PCBU on the pipeline. When constructing a TP through an obstacle - a ground or aboveground pipeline - a bridge is constructed that overlaps the obstacle with an entry and exit device, for which supports are installed on the sides of the obstacle on the soil surface and a plank flooring is supported on them, lined with panels of technical fabric and a layer is poured onto the panels sandy soil of estimated thickness.

Known protective structure of the intersection of the automobile pipeline, containing a pre-built road groove, which is internally provided with a support base (patent CN105088916). Such a protective structure for a road pipeline crossing point can be used for pipelines buried in a trench.

It is known to have a protective ramp having a central portion to provide a bridge over a buried pipeline or utility to prevent damage caused by heavy equipment passing through the pipeline. The ramp comprises a plurality of spaced beams extending from the leading to the trailing edge, a cover of parallel spaced tubes extends across the beams, and ramps are provided on the leading and trailing edges (CA 2366241).

Such structures require deepening of the pipeline, as a result of which they do not allow to quickly organize an effective car crossing.

A device and method for protecting a hose or other communication pipeline from damage caused by vehicles moving through such pipelines is known (US patent 5267367). The device is a single block of the safety lip, which has opposite lip plates forming its sides, a pipe channel formed between the inclined lip plates, a channel cover containing a horizontal plate at the level of the top of the lip and extending vertically down the channel to provide a protective cover for the channel . The block contains an element that protrudes outwards and upwards from the end of the block. The protection method includes blocking the ramps by inserting this element, which can be engaged with the inner surface of the neighboring block through the hole at the end of the neighboring block to form a chain of ramps across the roadway.

The known ramp device has one channel for laying one pipeline, which is closed by a stationary cover, as a result of which it cannot be used for a number of hose pipelines and operational access to the channel, which is necessary for control, repair and other work. The ramp is not collapsible, which creates problems during stacking, loading and transportation, it has fixed typical dimensions with a narrow crossing platform that cannot be expanded, which creates subsequent difficulties in the movement of the traffic through the crossing. Therefore, the invention is based on the problem of creating a safety collapsible structure, protecting a number of hose pipelines passing over the roadway, allowing for quick and economical transportation, installation and disassembly of the product, quick access to several hose pipelines.

The problem posed is solved and the technical result is ensured by the fact that the safety structure for the road crossing through hose pipelines passing over the roadway is a collapsible structure consisting of ready-made individual standard sections including a central channel section, a check-in section, a type-setting section, while the section the central channel is located between the stacking sections and contains internal compartments closed with a hinged lid, which serve to accommodate pipelines, and the stacking sections are connected to the drive-in sections for driving to the height of the central channel section and the exit on the opposite side, while the sections are equipped at the ends with pipes that are put on with a gap on each other, and pivotally connect the sections to each other.

The problem is solved and the technical result is ensured by the fact that the section of the central channel contains a steel base, partitions welded to the base, which create internal compartments, a cover that is mounted on supports on the axis on one side and is equipped with a latch on the side opposite from the axis, welded in pairs in at the opposite ends of the base, round connecting pipes inserted into the connection to the sections by inserting them into the counterpart.

It is advisable that the section of the central channel contains stiffeners welded to the base, steel sheets covering the compartments on the side, corners and a plurality of distributed expanded metal sheets welded to the corners, forming a horizontal driveway flooring.

The problem posed is solved and the technical result is ensured by the fact that the entrance or exit section contains a base made of steel sheet, the side edges of which are bent and obliquely protrude upward from the end to the maximum height of the central channel section, a stiffening rib made of steel sheet located in the center, welded to base, round connecting slip-on pipes, which are used to connect with sections by putting them on the counterpart, and welded to a plate built into the side edges of the base.

It is expedient that the entrance or exit section contains a plurality of steel expanded metal sheets welded into bends of a bent steel angle at the top of the base and forming an inclined road deck.

The problem posed is solved and the technical result is ensured by the fact that the stacking section contains a stacking section that includes a base made of steel sheet bent on the sides, a stiffening rib made of steel sheet placed in the center and welded to the base, round connecting slip-on pipes welded to the built-in plate, and inserted pipes welded in pairs at the opposite end from the plate at the bottom of the base.

It is advisable that the stacking section for the safety structure contains a steel corner, welded at the top to the edges of the base, a plurality of distributed steel expanded metal sheets, which are welded to the corner and form a horizontal driveway flooring.
