ることを特徴とする立坑構築の先導体装置。 A pressure support beam is provided along the axial direction of the shaft in a part of the circumferential direction of the liner plate, and the support beam is fixed to the ground of the shaft wall by anchor means toward the outer circumference, and a pressure support beam is provided at the tip. The guide body is press-fitted into the bottom of the mine by receiving a reaction force from the pressure support beam, and the earth and sand inside the press-fit guide body is excavated to advance the shaft, while liner plates are sequentially added above the guide body and the mine wall is In the guide body device for a shaft that is being constructed, a partition plate with a parallel or tapered cross section is installed in a cross shape on the outer cylinder at the tip of the guide body.
Further, depending on the soil conditions, the inside of the partition plates are connected in a lattice shape with parallel or tapered auxiliary partition plates to divide the inside of the tip of the guide body into arbitrary sizes. body equipment.
