Description

Construction of the waterproof system of the hole through the wall of the comprehensive pipe gallery

technical field

The invention relates to the technical field of comprehensive pipe gallery, in particular to the waterproof system structure of the wall-penetrating hole of the comprehensive pipe gallery.

Background technique

The comprehensive pipe gallery is a structure and ancillary facilities built underground to accommodate more than two types of urban engineering pipelines. The comprehensive pipe gallery effectively solves the problem of "road zipper" on urban roads, ensures the smoothness of urban roads, and helps to alleviate urban road congestion; at the same time, it also eliminates various urban overhead network lines such as electricity, telecommunications, and video TV, and beautifies the environment. The overall environment of the city creates better conditions for the life of urban residents, and after the pipelines enter the corridor, it is convenient for unified and centralized management and operation, which improves management efficiency, reduces the failure rate of pipelines, and guarantees the lifeline of urban life more efficiently and safely. However, various pipelines (roads) branch out through the wall of the pipe gallery, and the waterproofing of the holes through the wall faces various problems.

At present, the traditional method of waterproofing the hole through the wall of the integrated pipe gallery is poor in waterproof effect, mainly in the operation and maintenance stage, the waterproof period is difficult to control, the operation of the pipeline unit is difficult, and the outlet pipes leak seriously, which is very inconvenient for the operation and maintenance of the pipe gallery and pipelines. .

For example, the method of "02S404 Waterproof Casing" is mainly used for the waterproofing of holes through walls commonly used in engineering, which has the following shortcomings:

1. In the later stage, sealing materials are used to seal between pipelines and pipelines, pipelines and embedded casings. The service life of sealing materials is low, and water seepage and leakage between embedded casings and wall-through pipelines are serious during operation and maintenance;

2. The casing is poorly combined with the concrete of the structural wall of the pipe gallery, and it expands and contracts for a long time, and the gap between the embedded casing and the structure is prone to water leakage;

3. Pipeline penetration is carried out in stages, and the thickness and number of single-hole pipelines may be different. Pipeline plugging is difficult to deal with, and water is easy to leak;

4. There is no plugging measure for the outlet pipeline directly into the outlet well, which is easy to cause backflow;

5. When high-voltage cables pass through steel pipes or cast iron pipes, eddy currents are likely to occur, posing potential safety hazards.

Those skilled in the art are devoting themselves to research and development of a waterproof system structure for through-wall holes in a comprehensive pipe gallery to solve the above-mentioned technical defects.

In order to achieve the above-mentioned technical purpose, the present invention provides a waterproof system structure for the holes through the wall of the comprehensive pipe gallery, including the structural wall of the pipe gallery, a number of holes opened on the structural wall of the pipe gallery, and waterproof casings respectively pierced in each hole. In that: several water-stop rings are provided on the outer periphery of the waterproof casing located in the hole, and sealing components for sealing the waterproof casing are respectively provided at positions close to both ends of the waterproof casing; There are a number of openings for passing pipelines on the sealing assembly;

The two ends of the waterproof casing are respectively connected with outlet pipes;

The outlet pipes located outside the pipe gallery structural wall are connected to the waterproof casing through a flexible connection; the other outlet pipes located inside the pipe gallery structural wall are connected with the waterproof casing The outlet well casings pierced on the outlet wells are connected; the two ends of the outlet well casings are also respectively provided with the sealing components.

Preferably, the sealing assembly includes a sealing plate and a temporary water stop plate, and the sealing plate and the temporary water stop plate are connected by a detachable connecting piece;

A plurality of openings for passing pipelines are opened on the sealing plate, and the temporary water stop plate can seal all the openings on the sealing plate.

Preferably, both the sealing plate and the waterproof sleeve are made of non-metal matrix composite material.

Preferably, both ends of the waterproof casing are respectively provided with detachable sealing end caps.

Preferably, the other outlet pipe located inside the structural wall of the pipe gallery is provided with a drain hole plug inside.

Beneficial effects of the present invention:

1. The present invention uses a sealing component to seal the waterproof casing, and can achieve good sealing of the waterproof casing in the state of piercing the pipeline or not piercing the pipeline. Compared with the sealing material sealing method in the prior art , to avoid water seepage and leakage between the embedded casing and the wall pipeline, and has a longer service life.

2. A water-stop ring is set between the waterproof casing and the structural wall of the pipe gallery, which enhances the combination between the waterproof casing and the structural wall of the pipe gallery, and further avoids capillary leakage between the waterproof casing and the structural wall of the pipe gallery.

3. Each sealing component operates independently. When the pipeline is pierced, it only needs to remove the temporary water stop plate in the sealing component. According to the diameter of the pipeline to be threaded, openings with corresponding diameters are set up, so as to further ensure the good waterproof performance of the waterproof casing and the structural wall of the pipe gallery, and adapt to the threading requirements of pipelines with different diameters.

4. Drain hole plugs are set in the outlet pipes to prevent the accumulated water in the outlet wells from pouring back into the pipe gallery structural wall.

5. The waterproof casing and the sealing plate in the sealing assembly are made of non-metal matrix composite materials to avoid eddy currents when high-voltage cables are passed through, thereby eliminating potential safety hazards.
