Title:
SLIME SUCKING AND HARDENING MATERIAL INJECTING METHOD AND DEVICE
Document Type and Number:
Japanese Patent JP3904568
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To solve the problems of producing waste that a specially injected hardening material is discharged as slime, and thinning a built-up hardening material layer, since excessive suction may be caused, when ground internal pressure of the object ground exceeds a predetermined value, though conventionally an arrival distance of a hardening material jet is extended and the ground internal pressure is adjusted by sucking the generating slime when injecting a ground hardening material.
SOLUTION: An adjustably opening-closing shutter 55 is attached to a slime suction hole 5. A ground internal pressure measuring sensor 54 is arranged in a rod tip part. Slime suction corresponding to an internal pressure variation in the object ground by injection pressure of the hardening material, is performed by adjusting opening and closing of the shutter, and the excessive suction is prevented, and proper slime suction force is held.
