Description

Waterproof system structure for wall through hole of comprehensive pipe rack

Technical Field

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

Background

The utility tunnel is a structure and accessory facilities built under the city for accommodating more than two types of city engineering pipelines. The comprehensive pipe gallery effectively solves the problem of 'road zippers' of urban roads, guarantees the smoothness of the urban roads and is beneficial to relieving the problem of urban road congestion; meanwhile, various urban overhead network cables such as electric power, telecommunication, video television and the like are eliminated, the urban overall environment is beautified, better conditions are created for the life of urban residents, and unified centralized management and operation are facilitated after all the pipelines are arranged in a corridor, so that the management efficiency is improved, the pipeline failure rate is reduced, and the life line of urban life is guaranteed more efficiently and safely. But various pipelines (channels) are branched through the wall body of the pipe gallery and are led out, and the water prevention of the through-wall holes of the pipelines faces various problems.

At present, the traditional method for preventing the wall-through holes of the comprehensive pipe gallery from being waterproof is poor in waterproof effect, and mainly shows that the waterproof life is difficult to control, the operation of a pipeline unit is difficult, outlet pipelines leak water seriously, and the operation management and maintenance of the pipe gallery and the pipelines are very inconvenient in the operation and maintenance stage.

For example, the wall-through hole waterproofing commonly used in engineering mainly adopts the method of 02S404 waterproof casing, and the method has the following defects:

1. sealing materials are adopted between the pipelines and the pipeline and between the pipelines and the embedded sleeve in the later period for plugging, the service life of the sealing materials is low, and water seepage and water leakage between the embedded sleeve and the wall-penetrating pipeline are serious in the operation and maintenance period;

2. the sleeve is poorly combined with the concrete of the pipe gallery structure wall, expands and contracts for a long time, and a gap between the embedded sleeve and the structure is easy to have a water leakage phenomenon;

3. the pipeline penetration is carried out in stages, the thickness and the number of single-hole pipelines are possibly different, the pipeline plugging is difficult to process, and water leakage is easy to occur;

4. the corridor pipeline is directly led into the outlet well without a plugging measure, so that the backflow phenomenon is easy to generate;

5. the high-voltage cable is easy to generate eddy current when passing through a steel pipe or a cast iron pipe, and potential safety hazards exist.

Technical personnel in this technical field are dedicated to research and develop a utility tunnel wall hole waterproof system structure for solving the above technical defects.
