Receiving method for pipe pusher obliquely entering narrow receiving well in underground pipe pushing construction

Abstract

The invention relates to a receiving method for a pipe pusher obliquely entering a narrow receiving well in underground pipe pushing construction, which is characterized by comprising the following steps: after the pipe pusher is close to the receiving well, digging a hole door on the receiving well; making the front end of the pipe pusher partially enter the narrow receiving well by means of a power device at the rear end; and properly reinforcing an outer steel shell at the front end of the pipe pusher, detaching pipe pusher components connected with the steel shell of the pipe pusher and transporting the pipe pusher components away the receiving well; cutting off the outer steel shell of the pipe pusher in the receiving well, and hoisting the outer steel shell away the receiving well; and later, continuing the operations till the rest part of the pipe pusher fully enters the receiving well so as to finish the entering and receiving operation of the pipe pusher in the narrow receiving well. The receiving method has the advantage of solving the problem of narrow construction field; and meanwhile, only the steel shell of the pipe pusher is cut off section by section, but the core components inside the pipe pusher are completely reserved, and the components are reassembled after the steel shell is manufactured later to form the complete pipe pusher, so the method is economic.

Description

technical field [0001] The invention relates to a receiving method in which a pipe jacking machine obliquely enters a narrow receiving well during underground pipe jacking construction. Background technique [0002] At present, in order to use the underground space as much as possible in the construction of the city, there are a large number of pipe jacking constructions for underground tunnels. Now the construction technology of underground pipe jacking is generally used. It uses a pipe jacking machine to jack pipes from one working well to another. Wells are used to complete the construction of underground pipelines, which avoids the excavation of the ground and maintains the normal progress of ground traffic to the greatest extent. Usually, after the underground pipe jacking construction is completed, the pipe jacking machine should enter the receiving well, so as to complete the disassembly work of the pipe jacking machine in this space and take it out. Usually, the spa...

Problems solved by technology

The advantage of the present invention is to solve the problem that the construction site is narrow and small. At the same time, only the steel shell of the pipe jacking machine is cut off in sections, but the core components inside the pipe jacking machine are still completely preserved, and the steel shell will be reassembled later. parts to form a complete pipe jacking machine, thus saving money
