Ultra-high-performance concrete prefabricating and splicing integration pipe gallery system and construction method

Abstract

The invention provides an ultra-high-performance concrete prefabricating and splicing integration pipe gallery system which is formed by splicing a plurality of prefabricated sections. Each prefabricated section is prepared through ultra-high-performance concrete. Each prefabricated section is composed of a side plate, a bottom plate, a top plate and a partition plate. Each partition plate is fixed between the corresponding bottom plate and the corresponding top plate. The adjacent prefabricated sections are overlapped through ultra-high-performance concrete patches. The invention further discloses a construction method of the pipe gallery system. According to the integration pipe gallery system, the prefabricated sections of the integration pipe gallery system are made of materials like the ultra-high-performance concrete with high strength, high tenacity and high durability, the structure of the ultra-high-performance concrete patches and the like is combined, rigidity, bearing capacity and waterproof performance of a pipe gallery are improved, the wall thickness of the prefabricated sections is reduced compared with that of a traditional pipe gallery system, the dead weight of the pipe gallery is reduced remarkably, and transporting and hoisting are convenient. The material use amount of the pipe gallery is low to be 50% of that of the traditional pipe gallery system, the comprehensive production cost is reduced by 10-50% correspondingly, rigidity is large, the system is suitable for regions with poor foundation geologic conditions, the construction period of the pipe gallery system is short, and the influence on the construction environment is small.

Description

technical field [0001] The invention relates to equipment for construction of municipal facilities, in particular to an ultra-high-performance concrete prefabricated and assembled comprehensive pipe gallery system and a construction method. Background technique [0002] The comprehensive pipe gallery is to build a tunnel space under the municipal road, which integrates various engineering pipelines such as water supply and drainage, heat, gas, electricity, communication, radio and television, etc., and sets up special facilities such as inspection ports and feeding ports for unified construction management. Eliminating the independent structures and earthwork excavation of the pipeline itself can effectively and intensively utilize urban space resources. Its advantages are: one-time excavation, centralized construction, avoiding repeated excavation of the same road section; it greatly facilitates the maintenance and repair of municipal pipelines such as electricity, communic...
