Receiving-free well pipe jacking machine and complete recycling method thereof

Abstract

The invention relates to the technical field of pipe jacking construction and in particular relates to a receiving-free well pipe jacking machine and a complete recycling method thereof. A jacking direction of the pipe jacking machine is set to be a front side and a recycling direction of the pipe jacking machine is set to be a rear side; the pipe jacking machine is provided with a machine body ofthe pipe jacking machine and a supporting beam which is fixedly connected to the rear part of the machine body of the pipe jacking machine; the supporting beam is provided with a slippage oil cylinder; the slippage oil cylinder is provided with a slippage seat; the slippage seat moves in a front-rear direction along the supporting beam along the action of the slippage oil cylinder; the slippage seat is provided with a spreading shoe oil cylinder; the spreading boot supporting oil cylinder is provided with a spreading shoe; the spreading shoe is supported or gets far away from a pipeline underthe action of the spreading boot supporting oil cylinder. According to the receiving-free well pipe jacking machine and the complete recycling method thereof, provided by the invention, the pipe jacking machine can be completely recycled and the recycled pipe jacking machine can be used again; furthermore, when obstacles, which cannot be removed, are met at the front side in a pipe jacking and tunneling process, a vertical shaft does not need to be dug in front of the pipe jacking machine and the pipe jacking machine can be recycled firstly; after the obstacles at the front side are removed,jacking work is carried out again.

Description

technical field [0001] The invention relates to the technical field of pipe jacking construction, in particular to a pipe jacking machine without a receiving well and a complete recovery method thereof. Background technique [0002] As a trenchless pipeline burying construction method, pipe jacking construction is widely used in the trenchless laying of various pipelines such as urban underground water supply and drainage pipelines, natural gas and oil pipelines, and communication cables. Usually, an originating shaft and a receiving shaft are set up in the pipe jacking construction. The originating shaft is used for the downhole excavation operation of the pipe jacking machine and supporting mechanical parts and the downhole jacking operation of the pipeline, and the receiving shaft is used for the pipe jacking machine crane after the pipe jacking operation is completed. out recycling. [0003] However, in pipe jacking construction, it is usually encountered that the end o...

Problems solved by technology

[0003] However, in pipe jacking construction, it is usually encountered that the end of the pipeline is a river or ocean, or that the end of the pipeline is a hillside or a cliff, or that there are buildings on the road at the end of the pipeline, or there are existing buildings on the road at the end of the pipeline. Situations where receiving wells cannot be installed in the case of pipeline connections
