Embodiment Construction

[0008] When the pipe jacking machine 1 approaches the receiving well 2, a door 3 is dug on the receiving well 2 relative to the pipe jacking machine 1 on the pipeline, and a receiving frame 4 is built in the receiving well 2, and then the front end of the pipe jacking machine 1 rests on the The power unit part at the rear end enters the receiving tire frame 4 in the narrow receiving shaft 2, and after properly reinforcing the outer steel shell of the front end of the pipe jacking machine 1, first remove the pipe jacking machine parts connected to the steel shell of the pipe jacking machine 1 And transported away from the receiving well 2, after confirming that there is no component of the pipe jacking machine 1 within the projection range of the receiving well 2, cut off the outer steel shell of the pipe jacking machine 1 in the receiving well 2, and lift it away from the receiving well 2, and then lift After the pipe jacking machine 1 again relies on the power unit at the rear...

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...
