Underground comprehensive pipe rack segment waterproof splicing structure and installation method thereof

Abstract

The invention provides an underground comprehensive pipe rack segment waterproof splicing structure and an installation method thereof. The underground comprehensive pipe rack segment waterproof splicing structure comprises splicing grooves, wherein two steel angle cushion layers are arranged in the splicing grooves, and additional waterproof rubber layers are arranged on the steel angle cushion layers; a detachable water stop piece is arranged on the upper sides of the two steel angle cushion layers in the splicing grooves, and the detachable water stop piece, the waterproof rubber layers and the steel angle cushion layers are in screwing fastening connection with threads in one ends of fixing steel feet through nuts and are fixed into the splicing grooves; and a glue injecting conduit is placed on the lower side of the detachable water stop piece, and a blocking plate is placed on the upper side of the detachable water stop piece. According to the underground comprehensive pipe rack segment waterproof splicing structure, the waterproof performance is good, the force performance is good, the maintenance is convenient, and timely replacement when a waterproof structure at a splicing position is aged can be ensured due to the fact that the detachable water stop piece is installed at a splicing seam position; and by pre-burying the glue injecting conduit in the splicing seam position, the splicing seam position can be blocked effectively and rapidly, the repairing quality is effectively ensured, and the waterproof performance at the splicing position of a segment is enhanced.

Description

technical field [0001] The invention relates to an underground comprehensive utility gallery, in particular to an underground comprehensive utility gallery segment waterproof splicing structure and an installation method thereof. Background technique [0002] With the large-scale investment in infrastructure and the improvement of requirements for the environment, national defense, traffic volume and other conditions, the construction of subway tunnel pipe gallery has become the first choice for urban construction foundation. In order to prevent itself from cracking or damage, the underground pipe gallery segments are spliced The joint is a very important part; in case of deformation joint damage or water leakage, it may be necessary to destroy a large piece of rigid protective layer. The maintenance cost is high, the construction period is long, and the construction is very difficult. How to ensure that the pipe gallery is durable, waterproof, easy to construct, and conveni...
