Multiple shaft support frames are stacked in the vertical direction and fixed together between each pair of adjacent shaft support frames. After securing the upper shaft support frame, continue excavating the shaft downwards. After excavating to a certain depth, continue installing shaft support frames on the inner wall of the excavated shaft. The newly installed shaft support frames are then secured to the upper shaft support frame. The above steps are repeated cyclically to excavate the shaft section by section and install the shaft support frame; After the shaft is excavated, the starting hole for the pipe jacking machine and the installation hole for the integrated pusher are excavated on both sides of the shaft near the bottom. The integrated pusher is then installed in the installation hole.

[0005] Furthermore, in some embodiments of the present invention, each shaft support frame includes multiple steel templates connected end to end, and adjacent steel templates are fixedly connected by bolts and nuts.

[0006] Furthermore, in some embodiments of the present invention, along the vertical direction, every two adjacent shaft support frames are fixedly connected by bolts and nuts.
