Splicing construction method of corrugated steel pipe gallery

Abstract

The invention discloses a splicing construction method of a corrugated steel pipe gallery. The splicing construction of a plurality of splicing sections of the pipe gallery is conducted from back to front, the splicing construction method comprises the steps that A1, the splicing construction of the rear splicing section is conducted; A2, the splicing construction of the next splicing section is conducted; A3, the step A2 is repeated for many times until the splicing construction of all splicing sections of the pipe gallery behind the front connecting section is completed; and A4, the splicingconstruction of the front connecting section is conducted. According to the splicing construction method, the design is reasonable, the using effect is good, the splicing corrugated steel pipe gallery is integrally strengthened in sections by adopting a prestressed reinforcement structure, the structure and layout position of each prestressed reinforcement group in the prestressed reinforcement structure are limited, during the splicing process of the splicing sections of the pipe gallery, the prestressed reinforcement is conducted in synchronous sections, all the splicing sections of the pipe gallery in a pipe gallery body is integrally reinforced through the prestressed reinforcement structure, the integrity and mechanical performance of the constructed and formed pipe gallery can be effectively improved, and the durability of the pipe gallery can be effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of pipe gallery construction, and in particular relates to a splicing construction method of a corrugated steel pipe gallery. 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...

Problems solved by technology

[0004] However, in the actual use process, the corrugated steel structure pipe gallery has the following defects: First, the pipe diameter is too small: the pipe diameter is usually not greater than 3m, and the space provided is limited, which cannot meet the main line pipe gallery and the larger branch line pipe gallery Second, there is a lack of simple and effective splicing methods. At present, there are two main longitudinal splicing methods for corrugated steel pipe structures. The first is welding, and the second is flange and bolt connection, but the first method Th
