Abstract

PURPOSE: To prevent a collapse and a flood from a wall face by connecting and creating a long cylindrical hardened layer in sequence in the advancing direction along a pit section opening edge in the peripheral soil of the open cut object ground forming a canopy and an inner wall.
CONSTITUTION: An injection pipe 3 is arranged tiltably longitudinally and laterally via a position operation mechanism mounted on a self-propelled base 36. An excavation blade 31 and a side spray nozzle 32 are provided at the tip of an injection device 30, and the injection pipe 3 of a hardening agent or a lubricating water and a rotary drive mechanism 34 are provided at the rear end. The injection pipe 3 is rotated for excavation while water pressure is applied to an object ground wall face, then water is switched to the hardening agent, and the injection pipe 3 is retreated while the hardening agent is sprayed at a high pressure to form a cylindrical hardened layer. After the hardened layer is provided in parallel to form a lining body A in the ground, the ground is excavated to the length of the lining body A, then a similar lining body A' is formed, and these actions are repeated.
