Hole forming method in construction of filling, grouting and reinforcing soil layer around traction pipe

The invention relates to a hole forming method in construction of filling, grouting and reinforcing a soil layer around a traction pipe. The hole forming method in the construction of filling, grouting and reinforcing the soil layer around the traction pipe comprises the following steps that S1, guide hole drilling is started from a soil entering side until a drill rod drills out of the soil exiting side, and one-time guide hole drilling is completed; S2, a reamer is connected to the drill rod on a soil existing side, the reamer conducts reaming and drilling continuously from the soil existingside to the soil entering side, and finally the reamer drills out from the soil entering side; in the process, a pipeline locator is used on the ground along the track of a guide hole, the vertical distance between the ground and the reamer is measured at intervals of a certain distance and marking is carried out; S3, grouting holes are formed in all the mark positions, and the length of the grouting holes in all the mar
