Corrugated steel pipe gallery based on prestressed tendons

Abstract

The invention discloses a corrugated steel pipe gallery based on prestressed tendons. The corrugated steel pipe gallery comprises a pipe gallery body and a concrete base layer, wherein the pipe gallery body is formed in a way that a plurality of unit pipe galleries which are arranged in sequence are combined, a group of outer protection plates and inner protection plates are arranged between every two adjacent unit pipe galleries, the concrete base layer is laid on the bottom surface of the pipe gallery body, and first embedded parts and second embedded parts are embedded in the concrete base layer. The corrugated steel pipe gallery has the beneficial effects that the plurality of unit pipe galleries with the sections of arc-shaped structures are arranged in sequence, so that the mounting edges on both sides of the plurality of unit pipe galleries are connected with the first embedded parts of the concrete base layer in an inserted mode through first mounting holes, then fixed plates on the inner side surfaces of the plurality of unit pipe galleries are connected with the second embedded parts of the concrete base layer in the inserted mode through third mounting holes, and second nuts which are in threaded connection with the ends of the first embedded parts and the second embedded parts are matched, so that the assembly type installation of the corrugated steel pipe gallery is realized, and compared with a traditional corrugated steel plate splicing installation mode, the installation efficiency of the pipe gallery is effectively improved.

Description

technical field [0001] The invention relates to the field of corrugated steel pipe galleries, in particular to a corrugated steel pipe gallery based on prestressed tendons. Background technique [0002] Pipe gallery, that is, the corridor of pipelines. In recent years, my country's urbanization process has been accelerating, the city's comprehensive strength has been continuously enhanced, urban underground spaces have been continuously developed, and the importance of comprehensive utility corridors has been increasingly recognized by people. The comprehensive pipe gallery refers to the structures and auxiliary facilities built underground to accommodate two or more types of urban engineering pipelines. Various engineering pipelines such as heating, water supply and drainage are integrated into one body, with special inspection ports, hoisting ports and monitoring systems, and the implementation of unified planning, unified design, unified construction and management is an...

AI Technical Summary

Problems solved by technology

[0003] At present, the corrugated steel structure pipe gallery has been widely used in municipal engineering and highway engineering due to its advantages of high cross-section rigidity, industrial processing and easy on-site assembly, low cost, strong adaptability, and environmental protection. Limited by its own material factors, the overall durability of the pipe gallery is not high, and there are problems such as easy leakage inside the pipe gallery and frequent maintenance in the later stage
