Prefabricated splice pipe jacking system and construction method thereof

Abstract

A prefabricated splice pipe jacking system and a construction method thereof are provided. The prefabricated splice pipe jacking system comprises a main jacking mechanism and a spliced pipeline arranged along a design path of a designed pipeline; the inner diameter of the spliced pipeline is greater than the outer diameter of the designed pipeline; the spliced pipeline is formed by splicing splicepipes; the splice pipes are elongated plates, the front and rear edges of each splice pipe are correspondingly raised out to form axial lap edges respectively, and left and right edges of each splicepipe are correspondingly raised out to form peripheral lap edges respectively; the splice pipes that are coaxial are spliced in sequence through the axial lap edges along the axis of the spliced pipeline, and the splice pipes that are co-peripheral are spliced in sequence through the peripheral lap edges along the annular direction of the spliced pipeline; all the splice pipes are fastened via connectors. According to the construction method of the invention, a temporary spliced pipeline is spliced along a design path of a designed pipeline to provide powerful support for excavation and jacking processes; by using manual earth cutting to cooperate with pipe jacking construction, it is possible to meet the requirement for common construction conditions pipe jacking construction. The prefabricated splice pipe jacking system and the construction method thereof are widely applicable to pipe jacking construction.

Description

technical field [0001] The invention relates to the field of underground engineering, in particular to a pipe jacking construction system and a construction method. Background technique [0002] With the rapid development of science and technology, technological innovation plays an important role in all walks of life. For construction enterprises, it is undoubtedly an opportunity and a challenge. Among them, pipe jacking construction, as a relatively common non-excavation construction method, is a pipeline burying construction technology with no or less excavation. When open-cut construction is difficult and the excavation depth is greater than 5 meters, the groundwater level is high , suitable for non-excavation construction, that is, pipe jacking construction technology, mainly used in pipeline projects that are difficult to excavate, such as sewage pipeline projects, water supply and drainage pipelines, natural gas and oil pipelines, communication cables, etc. It can cro...
