Abstract

The invention discloses a two-way jacking pipe and a use method thereof in jacking pipe construction. The two-way jacking pipe comprises two jacks which are arranged in a jacking pipe well with one ends connected with a jacking block, tracks are arranged on two sides of the bottom of the jacking block, the other ends of the jacks are connected with a shaped steel backrest, and a jacking pipe pipeline is arranged on one side of the shaped steel backrest against the jacking block. The jacking pipe well can be excavated and jacked simultaneously on both sides, and time for jacking pipe construction is reduced; the jacking backrest of the jacking pipe pipeline is the prefabricated shaped steel backrest, reinforced concrete backrest construction carried out after completion of jacking pipe wellconstruction is not needed, time for construction can be reduced, the shaped steel backrest can be recycled, and the utilization rate of materials is increased.

Description

technical field

[0001] The invention relates to the technical field of municipal highway construction, in particular to a two-way pipe jacking used in pipe jacking construction and a method for using the same. Background technique

[0002] Pipe jacking construction is a non-excavation construction method. It is a pipeline burying construction technology without excavation or less excavation. It is mainly used in the current municipal highway engineering. The jacking force generated by the equipment overcomes the friction between the pipe and the surrounding soil, pushes the pipe into the soil according to the designed slope, and transports the earth away. After one section of pipe is pushed into the soil layer, the second section of pipe continues to be jacked. , the principle is to push the tool pipe or roadheader from the working pit through the soil layer to the receiving pit with the help of the thrust of the main top cylinder, the pipeline, and the relay room. Pipeline...
