At the beginning of the construction of the underlying corridor, a foundation pit needs to be constructed on the ground, the foundation pit needs to be hardened, and the hardened foundation pit is put into a pipe jacking machine and then the construction of the underground corridor is carried out.
The construction of the underground corridor requires embedding an embedded part on the wall of a foundation pit;
and then, a pipe jacking machine is adopted to start to beat soil from the preparation opening surface 4, and the pipe jacking machine is adopted to continuously extrude the prefabricated annular concrete body unit in while continuously homogenizing the soil, so that the rapid construction of the lower pipe gallery is realized.
In the actual construction process, the foundation pit is generally selected to be in a standard shape such as a rectangle.
However, in essence, urban terrain is very complex, and sometimes only a special-shaped foundation pit can be prepared, and the intersecting surfaces of the underground gallery to be excavated and the foundation pit surface of the special-shaped foundation pit are inclined.

Therefore, in order to adapt to various terrains, the damage of an initial cutter head in the special-shaped foundation pit is avoided, and the condition that part of concrete bodies are suspended is avoided. A new structure is urgently needed.
