Semi-prefabricated comprehensive pipe rack and construction method thereof

Abstract

The invention relates to a semi-prefabricated comprehensive pipe rack and a method. The comprehensive pipe rack comprises a cast-in-situ bottom plate, prefabricated pipe rack segments, asphalt masticlayers and waterproof concrete structures, annular grooves are formed in the bottom plate and corresponds to wall plates, each prefabricated pipe rack segment comprises an integrally formed top plateand a plurality of wall plates vertically connected with the top plate, the wall plates are inserted into the corresponding annular grooves, two adjacent pipe rack segments are fixedly connected by acast-in-situ connection section, the annular grooves are filled with the asphalt mastic layers, a set distance is reserved between the top of each asphalt mastic layer and a notch of each annular groove, the waterproof concrete structures are poured in the annular grooves and positioned on the asphalt mastic layers, and the notches of the annular grooves are sealed by the waterproof concrete structures. The cast-in-situ bottom plate is connected with the prefabricated wall plates by cup groove joint structures, reinforcement lapping and binding construction of prefabricated parts and cast-in-situ parts are avoided, construction is simple, and construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of construction engineering of a comprehensive pipe gallery, in particular to a semi-prefabricated comprehensive pipe gallery and a construction method thereof. Background technique [0002] With the continuous advancement of modern urban construction, the construction of comprehensive pipe corridors in my country is also developing. In 2015, the construction scale of underground comprehensive pipe corridors in 69 cities across the country was about 1,000km. The construction of urban underground comprehensive pipe gallery has become one of the important contents of my country's urban infrastructure construction in the future. There are two ways to construct the traditional underground comprehensive pipe gallery: 1. On-site casting, 2. Factory prefabrication. [0003] The construction of the cast-in-place integrated pipe gallery is simple and the technology is mature. However, since all operations are completed on si...
