Construction Method of Prestressed Reinforced Concrete Sewage Interceptor Pipe Jacking

Abstract

The invention discloses a method for constructing a top pipe of a prestressed reinforced concrete sewage intercepting pipe. The method comprises the following steps: 1, conducting exploration on the engineering geology condition below the pipe location of the sewage intercepting pipe, and conducting preliminary plane design on a pipe network; 2, conducting supporting and excavation on work pits; 3, installing a process platform of the top pipe and special facilities of the top pipe; 4, constructing the top pipe. According to the method, in medium or small size engineering, the mode of combining mechanical jacking and manual excavation is adopted, construction cost is low, operation is simple, influence on the surrounding environment is small, construction can be conducted day and night, and construction quality is stable.

Description

technical field [0001] The invention relates to a pipe jacking construction method, in particular to a pipe jacking construction method of a prestressed reinforced concrete sewage intercepting pipe. Background technique [0002] At present, in the construction of underground pipelines, it is often necessary to dig trenches underground to lay pipelines and repair pipelines. The construction period of excavation is very long, especially the underground pipelines in the urban center section are very dense, and the pipelines overlap and overlap. The laying of new pipelines cannot be carried out through traditional excavation methods, and if there are buildings on the surface, excavation will not be possible. Excavating roads in busy cities will bring great inconvenience to traffic and people’s lives. Usually It is necessary to set up special roadblocks and then close the construction to prevent safety accidents. However, due to the traffic pressure or the flow of people and traf...

[0002] At present, in the construction of underground pipelines, it is often necessary to dig trenches underground to lay pipelines and repair pipelines. The construction period of excavation is very long, especially the underground pipelines in the urban center section are very dense, and the pipelines overlap and overlap. The laying of new pipelines cannot be carried out through traditional excavation methods, and if there are buildings on the surface, excavation will not be possible. Excavating roads in busy cities will bring great inconvenience to traffic and people’s lives. Usually It is necessary to set up special roadblocks and then close the construction to prevent safety accidents. However, due to the traffic pressure or the flow of people and traffic on some major traffic arteries, it is not convenient to close the construction, which has caused difficulties for the traditional construction method; using long distance Fully mechanical jacking technology and equipment, high cost and great damage to surrounding structures
