A structure in which pipe section connectors are fitted and installed between two pipe gallery pipe sections by straight line connection

Abstract

A pipe segment connecting component for a comprehensive bamboo composite pipe gallery. The pipe segment connecting component is integrally embedded into an annular insertion opening at each end part of adjacent two pipe segments in a pipe gallery, and the cross section of a coupling part of the connecting component is a wedge-shaped structure; the wedge-shaped structure is constituted of a horizontally extended flat upper surface, a left side surface and a right side surface that vertically extend and are parallel to each other, and a ridge-shaped lower surface that is left-right symmetric; two sides of the ridge-shaped lower surface each have a slope gradient of 5-10 degrees along a center line.

Description

technical field [0001] The invention belongs to the related field of supporting equipment of a pipe gallery, and more specifically relates to a structure in which pipe section connectors are fitted and installed between two pipe gallery pipe sections by linear connection. Background technique [0002] The comprehensive pipe gallery is a public tunnel laid underground in the city for the centralized laying of municipal pipelines such as electricity, communications, water supply, drainage, heat and gas. my country is in a period of rapid development of urbanization, but in contrast, the construction of underground infrastructure is seriously lagging behind. In 2013, the State Council issued the "Opinions on Strengthening Urban Infrastructure Construction" (Guo Fa (2013) No. 36), which proposed for the first time that it plans to carry out pilot projects for urban underground comprehensive pipe corridors, and comprehensively launch underground construction in many large and med...

The search found that CN20161061389.2 proposed a structure that uses mortises and wedge heads to match, and preset waterproof sealing gaskets between the contact surfaces; CN20161054494.0 proposed a welding method to connect the connector A method for performing welding of parts, CN20161008215.0 proposes a method of inserting a pair of pull connectors into adjacent segments to reserve a lifting point; however, the above-mentioned prior art is designed for the connection of pipe sections in reinforced concrete structures , usually need to perform welding and other operations or must process embedded parts for the pipe section, which not only easily increases the complexity and difficulty of the overall construction, greatly reduces the construction efficiency, but also often cannot provide good pipe section sealing performance in actual use
