Pipe jacking construction vertical shaft opening grouting structure and using method thereof

The invention discloses a grouting structure for a vertical shaft opening in pipe jacking construction. An annular space is formed between a hole formed by jacking when a machine head of a jacking pipe advances and a pipe joint of the jacking pipe; a grouting pump is arranged on the ground outside the vertical shaft, and an outlet of the grouting pump is connected with a grouting hose; a soil body reinforcing area is arranged at the rear part of the annular space around the annular space; an annular pipe is pre-embedded in the front end of the soil well wall area around the annular space and provided with a slurry outlet, and the slurry outlet communicates with the annular space. The annular pipe is connected with a grouting connector through a connecting pipe, the grouting connector is fixed to the shaft wall of the vertical shaft and connected with a grouting hose, and a hole annular sealing device is arranged at the hole around the annular space. By arranging the soil body reinforcing ...
