Waterproof construction method outside cross pipe gallery

Abstract

The invention discloses a waterproof construction method for the exterior of a crossing pipe gallery. The side walls of the main pipe gallery and the secondary pipe gallery are located at a certain distance above the top surface of the bottom plate, and a concrete cushion is laid on the bottom of the foundation pit. Build the guide wall, tamp and level the soil outside the guide wall to below the top surface of the guide wall, then lay a concrete cushion to be flush with the top surface of the guide wall, and place the concrete cushion on the bottom plate of the secondary pipe gallery on both sides of the side wall of the secondary pipe gallery Build the guide wall, pre-lay the waterproof coiled material on the bottom plate and side wall of the main corridor and the bottom plate of the secondary corridor, and pre-lay a waterproof reinforcement layer on the sun corner of the roof of the secondary corridor to waterproof the intersection of the side wall of the secondary corridor and the roof of the main corridor , Waterproof the side wall above the bottom plate of the secondary pipe gallery, and protect the waterproof membrane. The method realizes seamless laying of the waterproof membrane at the intersection pipe gallery, reduces stress concentration of the membrane and damage to the waterproof membrane, has good waterproof effect, simple construction, and saves construction period.

Description

technical field [0001] The invention belongs to the field of construction of a comprehensive pipe gallery, and in particular relates to a waterproof construction method outside a cross pipe gallery. Background technique [0002] Such as figure 1 As shown, the cross pipe gallery is at the junction of the main and secondary pipe galleries. Once there is a leak, it will affect the normal use of other pipe galleries. The roof of the main corridor at the junction of the main and secondary corridors is shared with the bottom plate of the secondary corridor. It is difficult to lay waterproof rolls at the corners of the junction between the bottom plate of the secondary conduit corridor and the side wall of the main corridor. If waterproof measures are not in place, it is easy to cause water leakage at this place , and leak-trapping measures are difficult to implement. Contents of the invention [0003] The purpose of the present invention is to provide a waterproof construction...

AI Technical Summary

Problems solved by technology

[0002] like figure 1 As shown, the cross pipe gallery is at the junction of the main and secondary pipe galleries. Once there is a leak, it will affect the normal use of other pipe galleries

The roof of the main corridor at the junction of the main and secondary corridors is shared with the floor of the secondary corridor. It is difficult to lay waterproof rolls at the junction of the bottom plate of the secondary conduit corridor and the side wall of the main corridor. If the waterproof measures are not in place, it is easy to cause water leakage at this place , and leak-trapping measures are difficult to implement
