Semi-rigid assembly type comprehensive pipe gallery and construction method thereof

Abstract

The invention discloses a semi-rigid assembly type comprehensive pipe gallery. The semi-rigid assembly type comprehensive pipe gallery comprises a main pipe gallery body, the main pipe gallery body is formed by connecting a plurality of standard prefabricated sections in series, a water-swelling sealing rubber ring construction groove is reserved in the whole perimeter of the cross section of the standard prefabricated segments, an upper haunch corner and the a lower haunch corner of the pipe gallery are arranged in a non-full-length mode and are interrupted by 0.5 m in the middle of the prefabricated pipe gallery, a circular prestressed steel strand channel is reserved in the middle of the haunch corners in a full-length mode, and a drainage side ditch is reserved in the inner side, close to a pipe gallery cavity body, of the lower haunch corner of the pipe gallery. According to the semi-rigid assembly type comprehensive pipe gallery, the physical and mechanical properties of prestressed steel strands are utilized, the prefabricated pipe gallery forms a semi-rigid structure body, and therefore the problems of groundwater leakage and the like caused by differential settlement among different sections of a conventional rigid assembly type pipe gallery are effectively avoided.

Description

Technical field: [0001] The invention belongs to the technical field of urban underground building construction, and in particular relates to a semi-rigid assembled comprehensive pipe gallery and a construction method thereof. Background technique: [0002] The comprehensive pipe gallery refers to the structures and auxiliary facilities built underground in the city to accommodate two or more types of urban engineering pipelines. The prefabricated comprehensive pipe gallery refers to the integrated integrated pipe gallery that is cast in sections in the factory and assembled on site. pipe gallery. [0003] Because the traditional direct buried pipeline occupies a lot of underground space under the road, the laying of the pipeline is often not synchronized with the construction of the road, resulting in frequent excavation of the road, which not only affects the normal traffic of the road, but also brings environmental pollution such as noise and dust. At the same time, ther...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to overcome the closure deviation between the splicing segments of the prefabricated pipe gallery at the present stage and the leakage of groundwater caused by the large difference in foundation settlement in the later operation of the pipe gallery. Under the conditions of various requirements, develop a prefabricated comprehensive pipe gallery and its construction method that has a short construction period, is easy to construct accurately and can adapt to large differences in foundation settlement
