A splicing construction method of corrugated steel pipe gallery

Abstract

The invention discloses a splicing construction method of a corrugated steel pipe gallery, in which a plurality of splicing sections of the pipe gallery are respectively spliced ​​and constructed from back to front, comprising steps: A1, splicing construction of the splicing section at the rear end; A2, next splicing section Splicing construction; A3. Repeat step A2 several times until the splicing construction process of all pipe gallery splicing sections on the rear side of the front connecting section is completed; A4. Splicing construction of the front connecting section. The present invention is reasonable in design, simple in construction, and good in use effect. It uses a prestressed reinforcement structure to carry out segmental overall reinforcement of the spliced ​​corrugated steel pipe gallery, and limits the structure and layout position of each prestressed tendon group in the prestressed reinforcement structure. , during the splicing process of the pipe gallery splicing section, the prestressed reinforcement is carried out synchronously and segmentally, and all the pipe gallery splicing sections in the pipe gallery body are integrally reinforced by the prestressed reinforcement structure, which can effectively improve the integrity and mechanical performance of the constructed pipe gallery , and can effectively prolong the durability of the pipe gallery.

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...

AI Technical Summary

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 The construction speed is slow and the labor cost is high. Although the second method is faster in construction, it does not give full play to the structural characteristics and advantages of corrugated steel, and damage and leakage are prone to occur in the longitudinal connection parts; third, corrugated steel Poor structural durability and poor mechanical performance, especially the long-distance large-diameter spliced ​​pipe gallery, poor integrity and poor mechanical performance, there will inevitably be many damaged parts, and the later maintenance workload will be large
