UHPC prefabricated assembled comprehensive pipe gallery horizontal curve connecting segment structure and construction method

Abstract

The invention discloses a UHPC prefabricated assembled comprehensive pipe gallery horizontal curve connecting segment structure and a construction method. The structure is composed of side plates, a bottom plate, a top plate, short partition plates, an inlet and through openings; a connecting segment is connected with a prefabricated pipe gallery segment through the inlet or the through openings;tensioning hole channels are reserved in the connecting segment, and the connecting segment is connected with the prefabricated pipe gallery segment through prestressed tendons; and the UHPC connecting segment has a reasonable structure and a firm and reliable connecting mode so that the angle adjustment and curve transformation of a prefabricated pipe gallery segment laying route can be achieved,the UHPC connecting segment is suitable for zones where the geological condition of foundations is poor, a joint is good in waterproof performance and high in durability, and the flexibility of the prefabricated assembled pipe gallery laying route is improved. According to the UHPC prefabricated assembled comprehensive pipe gallery horizontal curve connecting segment structure and the construction method, the development of the full-prefabricated assembled comprehensive pipe gallery technology is promoted, the durability, rigidity and waterproof performance of a pipe gallery are greatly improved, and the good engineering significance is achieved.

Description

technical field [0001] The invention relates to the field of municipal facilities construction, in particular to a UHPC prefabricated and assembled comprehensive pipe gallery flat curve connection segment structure and construction method. Background technique [0002] Comprehensive pipe gallery refers to the construction of a tunnel space under the municipal road, which integrates various engineering pipelines such as drainage, heat, gas, electricity, communication, radio and television, etc., and sets up special inspection ports, feeding ports and other facilities for unified construction management. Eliminating the independent structures and earthwork excavation of the pipeline itself can effectively and intensively utilize urban space resources. The urban underground comprehensive pipe gallery is one of the symbols of modernization, technology and intensification of urban construction, and it is the infrastructure for making full use of urban underground space and ensuri...

AI Technical Summary

Problems solved by technology

[0004] However, in the construction of the prefabricated integrated pipe gallery, factors such as section size standard prefabrication and section tension connection are taken into account. The laying route of the prefabricated pipe gallery section can only be a straight line. If factors such as important buildings or unfavorable locations need to change the laying direction, only cast-in-place construction technology can be used to construct the turning section, which greatly slows down the construction speed. In combination, the construction of fully prefabricated integrated utility corridors has not yet begun to be popularized
