Assembled type jacking pipe piece structure and assembling method thereof

Abstract

The invention discloses an assembled type jacking pipe piece structure and an assembling method thereof. The assembled type jacking pipe piece structure is characterized in that pre-buried steel plates for connection are arranged inside a pipe piece; a reservation grouting device is arranged inside the pipe piece; a slurry outlet of the reservation grouting device is formed in the assembled surface of the pipe piece. The assembled type jacking pipe piece structure has the following advantages: (1) the pipe piece is integrally formed by virtue of the effective connection between the pre-buried steel plates on the inner arc surface and the outer arc surface of the pipe piece, so that the stress and deformation requirements of the jacking pipe in pipeline construction and usage stages can be met; (2) the gap of the pipe piece is filled by pressure grouting by virtue of a pre-buried grouting device, so that the problem of water leakage at joints of the pipe piece can be effectively solved; (3) epoxy anticorrosive paint is coated to the inner side and the outer side of the pipeline, so that the pipeline durability can be improved; (4) by virtue of the connection manner, large-diameter jacking pipe joints can be transported by a manner of dividing the pipe joints into pieces, so that the problem that the large-diameter jacking pipe joints are difficultly transported can be solved.

Description

technical field [0001] The invention belongs to the technical field of pipe jacking connections, and in particular relates to an assembled pipe jacking segment structure and an assembling method thereof. Background technique [0002] With the development of social economy, the acceleration of urbanization process and the continuous increase of urban population, the problems of infrastructure construction and maintenance have become increasingly prominent, seriously restricting the development of urban economy and affecting the quality of life of urban residents. Laying new gas, heat, electricity, water supply and drainage and other underground pipelines and underground passages has become more and more difficult and even difficult to implement. As one of the trenchless construction techniques for underground pipelines, pipe jacking is very suitable for urban areas with heavy traffic, dense population, numerous ground buildings, complex underground structures and pipelines. ...

AI Technical Summary

Problems solved by technology

[0003] From the point of view of stress and pipe jacking construction capacity, there is no technical problem in large-diameter pipe jacking, but when using the pipe jacking method to construct large-diameter pipes (pipelines with a diameter of 3.50m-5.00m), the transportation of pipe joints becomes a major problem during construction. big problem

Since the pipe jacking uses the whole section of pipe jacking, and the length of each pipe section is 2m or 2.5m, there is a problem of super-wide or super-high pipe section transportation, which is an important factor restricting the development of large-diameter pipe jacking
