Temporary blocking wall structure of comprehensive pipe rack and construction method

Abstract

The invention discloses a temporary blocking wall structure of a comprehensive pipe rack and a construction method. The structure comprises H1 structural steel, H2 structural steel, H3 structural steel, H4 structural steel and a sealing plate; the H1 structural steel, the H2 structural steel and the H3 structural steel are welded and connected to form a plugging framework; the bottom of the plugging framework is provided with a waterproof mortar cushion layer; the joint of the plugging framework and the comprehensive pipe rack is provided with a polysulfide sealing paste layer; the plugging framework is connected with the upper face and the lower face of the comprehensive pipe rack in a sealed manner through the waterproof mortar cushion layer and the polysulfide sealing paste layer; the sealing plate is arranged on the plugging framework in a welded manner; the H4 structural steel is fixedly arranged on the inner side of the sealing plate; the two ends of the H4 structural steel are both fixed in a comprehensive pipe rack wall body through bolts; and a temporary blocking wall is fixed. The temporary blocking wall structure of the comprehensive pipe rack is simple, the construction process is mature, safe and reliable, the polysulfide sealing paste and the waterproof mortar cushion layer are adopted, the sealing performance is good, the safety performance is high, the waterproof performance is good, the safety of an original structure cannot be affected after disassembling, and thus the temporary blocking wall structure of the comprehensive pipe rack is suitable for application and popularization.

Description

technical field [0001] The invention belongs to the technical field of construction of a comprehensive utility gallery, and in particular relates to a brand-new temporary sealing wall structure and a construction method of a comprehensive utility gallery for the connection between a completed comprehensive utility gallery at an intersection and a comprehensive utility gallery to be constructed in the next stage. Background technique [0002] The comprehensive pipe corridor is a new type of municipal pipeline tunnel. In recent years, with the advancement of domestic urbanization, more and more new urban areas are planning to build comprehensive pipe corridors. The pipelines contained in the comprehensive pipeline gallery include power cables, communication and control optical cables, water supply pipes, hot water pipes, etc., which can reduce the trouble of repeated excavation of the road surface caused by burying or repairing pipelines, delay the life of pipelines, and save v...
