Description

Technical Field

[0001] The utility model relates to the technical field of pipe pushers, in particular to a large-slope pipe pusher. Background Art

[0002] In the reverse drilling work, most of the time, a drill bit is used to form a channel along a predetermined path underground. This channel often has a certain inclination angle to reserve a space suitable for installing pipelines. After the reverse drilling is completed, a pipe pusher is needed to introduce the pipeline into the channel. The pipe pusher uses the propulsion force provided by the hydraulic system to push the pipeline from one end to the other.

[0003] At present, when the existing pipe pushers are in use, during the directional drilling work of the reverse drilling, because the channel they open has a certain angle, in which some underground environments are relatively complex, the existing pipe pushers cannot better adapt to the specific underground environment during directional pipe pushing, which may cause the pipeline to fail to be smoothly pushed forward.
