The jacking pipe is a construction technology for constructing underground space in a non-excavation mode, has the remarkable advantages of low comprehensive cost, low traffic interference and the like compared with construction methods such as shield, open excavation and the like, and plays an important role in municipal engineering crossing dense areas of pipelines and traffic trunks. In general, pipe jacking construction is mainly performed on straight pipe, namely, an originating end working well end wall and a receiving end working well end wall are perpendicular to the tunneling axis direction of the pipe jacking. However, with the continuous development of underground engineering, the urban underground space relationship becomes complex slowly, and as shown in fig. 1 and 2, the conditions of adjusting the well position of the receiving end working well 30 and the like sometimes exist due to the change of external environmental conditions, so that the pipe jacking axis is inclined with the end wall of the receiving end working well 30. When the oblique crossing condition exists, the redundant part of the pipe joint at the oblique crossing is often required to be cut and then connected and fixed with the post-cast ring beam. At present, the pipe joint is connected with the post-cast ring beam through connecting steel bars. Specifically, during connection, a hole is drilled on a section of a pipe joint, then a connecting steel bar which is connected with a post-poured ring beam is implanted, and finally glue is filled in the hole to realize stable connection of the connecting steel bar and the pipe joint. However, the operation is complex, the convenience of construction is not facilitated, and the structural strength of the pipe joint is reduced after the section of the pipe joint is drilled.

It should be noted that, post-cast ring beam is the ring beam that sets up around tube coupling circumference, and it can prevent that the muddy water in tube coupling and the tunnel hole space from getting into tube coupling or working well in, can also play the supporting role simultaneously.

To this, this application provides a push pipe section 10, and this push pipe section 10 has higher structural strength, and can also effectively improve the convenience of push pipe work progress.

In the pipe section 10, the retention segment 110 and the cutting segment 120 are surrounded to form an annular structure, so that the pipe section 10 can be ensured to perform the punching operation. In addition, since the retaining segment 110 and the cutting segment 120 are respectively connected to two sides of the first steel plate 130, that is, the retaining segment 110 and the cutting segment 120 are connected through the first steel plate 130, when the pipe section 10 of the pipe jacking pipe needs to be cut, the cutting segment 120 can be directly cut along the first steel plate 130 to be cut off from the first steel plate 130 and the first steel plate 130 is exposed, so that each connecting steel bar connected with the ring beam can be directly welded on the first steel plate 130 to realize the support of the ring beam to the pipe section, the connecting steel bars do not need to be implanted after holes are drilled one by one on the cutting surface of the pipe section 10 of the pipe jacking pipe, and the pipe section 10 of the pipe jacking pipe cannot be damaged, and the structural strength of the pipe jacking pipe is reduced.
