摘要： PROBLEM TO BE SOLVED: To collect crushed pieces of an existing embedded pipe, without requiring open-cut and using a screw auger. SOLUTION: A start pit 2 and an arrival pit 3 are drilled at a start end position of the existing embedded pipe 1 requiring renewal and at a finish end position thereof, respectively. A crushing cutter 11 is connected to a propelling device 4, set up in the start pit 2 for crushing the existing embedded pipe 1 pressed to the direction of reducing its diameter by propulsion, in contact with the pipe end outer periphery of the existing embedded pipe 1. The crushed pieces 1a are collected out of the arrival pit 3 by using the crushing cutter 11 propelled by the propelling device 4, and the old embedded pipe is replaced with new one, by using the propelling device 4 for pushing and embedding a renewal pipe 1A in a propulsion track of the crushing cutter 11.

摘要： PROBLEM TO BE SOLVED: To provide a recycling method for a surplus liquid hardener, which is very easy and economical and for use in the soil cement mixing method. SOLUTION: The soil cement mixing method for use in constructing an underground wall, etc., is carried out by mixing the liquid hardener discharged from an auger head and in-site soil excavated by an auger with each other, and agitating the resultant mixture. The recycling method for the surplus liquid hardener is adopted in the soil cement mixing method, and comprised of the following steps. That is, in the first step, the surplus mixed soil of the excavated in-site soil and the liquid hardener, which is discharged during excavation and agitation, is recovered by an surplus liquid sucking vehicle 10. In the second step, the recovered surplus mixed soil is separated into the soil and the surplus liquid hardener, by a separator 20 comprised of a mud screen and a cyclone. In the subsequent step, the separated surplus liquid hardener is supplied to the auger head 41 again.

摘要： PROBLEM TO BE SOLVED: To carry out gripping surely without damaging a casing by a chuck spacer when biassed collision against the casing of the chuck spacer is generated due to the variation of the accuracy of manufacture. SOLUTION: The chuck is constituted so that one of the three chuck arms 16, 17 of a one-third arc mutually having arcuate inner circumferential surfaces having the same curvature is fixed onto a support frame, one end sections of the other chuck arms 17 are connected at both end sections of the fixed chuck arm 16 in a rockable manner on the same surface and the outer circumferential surface of the casing C is gripped by the inner circumferential surfaces of the three chuck arms 16, 17. The chuck spacer 32 of an approximately one- third arc, in which the radius of curvature of an outer circumferential surface is made slightly smaller than those of the inner circumferential surfaces of the chuck arms 16, 17 and the radius of curvature of an inner circumferential surface is equalized to that of the outer circumferential surface of the casing C to be gropped, is coupled with the chuck arms 16, 17 respectively so as to be able to be slightly rolled on the inner circumferential surface of the chuck arm 16 by the outer circumferential surface.
