Longitudinal dynamic waterproof structure of underground pipe gallery and construction method thereof

Abstract

The invention discloses a longitudinal dynamic waterproof structure of an underground pipe gallery and a construction method thereof. The longitudinal dynamic waterproof structure comprises a first elastic adjusting assembly, a second water stop protection part and a V-shaped rubber filling part, the section, in the horizontal direction, of a longitudinal expansion joint between every two adjacent underground pipe gallery sections is in a V shape, and a V-shaped opening of each longitudinal expansion joint faces the outer side of the corresponding underground pipe gallery section; and the first elastic adjusting assembly comprises a first protective supporting plate, a first fastening screw rod, a first fastening pressure spring and a first fastening nut, and a first connecting hole matched with the first fastening screw rod is formed in each underground pipe gallery section. Dynamic sealing of the longitudinal expansion joints of the underground pipe gallery can be achieved, the possibility of water seepage of the longitudinal expansion joints can be greatly reduced or avoided through multi-stage sealing and dynamic compensation, and the service life requirement of long-period use of the underground pipe gallery can be met. According to the dynamic waterproof structure, materials are easy to obtain, the structure is stable and reliable, the waterproof effect is remarkable, and the dynamic waterproof structure has high application value and good application prospects.

Description

technical field [0001] The application relates to the field of building facilities, especially the field of waterproof construction of urban underground pipe galleries, and specifically relates to a longitudinal dynamic waterproof structure of underground pipe galleries and a construction method thereof. Background technique [0002] Urban underground pipeline construction is one of the safety line projects for urban operation, and plays a key role in the normal operation of the city. Urban underground pipeline construction generally has two methods: traditional pipeline laying and underground pipe gallery. The underground pipe corridor is to build a tunnel space underground in the city. It integrates various engineering pipelines, sets up special inspection ports, hoisting ports and monitoring systems, and implements unified planning, design, construction and management. It is an important basis for ensuring urban operation. facility. Compared with traditional pipeline la...
