Problems solved by technology

Due to the section size and self-heavyness of pipe joints, it is difficult to transport, hoist and store, especially in the central urban area, where the road width and construction site are limited, which greatly limits the application and development of large-section pipe jacking
Assembled pipe jacking technology is an effective measure to solve the above problems, but the existing domestic assembly technology has complicated assembly methods and low construction efficiency

Abstract

The invention discloses a slide-in assembled pipe jacking joint, comprising: an upper pipe joint, a lower pipe joint, and a joint assembly connecting the contact surfaces of the upper pipe joint and the lower pipe joint, and the joint assembly adopts Slide-in connection; the present invention also provides a construction method for slide-in assembled pipe jacking joints. The invention divides the integral prefabricated pipe jacking joint into upper and lower parts and adopts slide-in assembly, has a simple structure, reduces the transportation size and quality of the pipe joint, and has the beneficial effects of convenient transportation, storage and installation.

Description

technical field [0001] The invention relates to the field of pipe jacking engineering. More specifically, the present invention relates to a slide-in assembled pipe jacking joint and its construction method. Background technique [0002] With the acceleration of urbanization, urban underground space has been more and more developed and utilized. Due to its unique advantages in urban environment construction, pipe jacking method has been widely used in urban underground space engineering. In order to expand the use space of underground pipelines, underground traffic lanes, and comprehensive pipe galleries, the cross-sectional area of ​​pipe jacking pipe joints is getting larger and larger. Due to the cross-sectional size and self-heavy weight of pipe joints, transportation, hoisting and storage are difficult, especially in central urban areas, where road width and construction sites are limited, which greatly limits the use and development of large-section pipe jacking. As...
