摘要： PROBLEM TO BE SOLVED: To positively crush an existing conduit even if it is a long or curved one, by following the conduit, and to replace the existing conduit by a new one. SOLUTION: In implementation of replacement, a propeller 4 arranged in a starting shaft 1 has the plurality of new pipes 7 connected thereto in a manner being foldable with respect to each other, and a large-diameter cutting bit 9 is rotatively mounted on the tip of the new pipes 7. Then a plurality of clevis augers 10 connected to the propeller 4 are foldably connected to the interior of the new pipes 7, and an inner cutting bit 11 arranged on the periphery of the tip of the clevis augers 10 and the large-diameter cutting bit 9 are rotated together in one body, followed by attaching one end of a towing wire 12 penetrated from an arrival shaft 2 into the existing Hume pipe 3, to the tip of the clevis augers 10, to thereby tow the clevis augers 10 by the towing wire 12. Further while the tip of the clevis augers 10 is pinched by an opening at one end of the existing Hume pipe 3, the inner cutting bit 11 etc. are rotated to crush the existing Hume pipe 3, and thus the new pipes 7 are laid in the ground.

摘要： PROBLEM TO BE SOLVED: To provide a water stop material capable of maintaining a cut-off function excellent over a long period of time at a low cost.
SOLUTION: The water stop material for stopping water by providing it in a void in an underground structure is formed by compounding bentonite, a thermoplastic resin, a plasticizer and a water absorptive resin as main ingredients. The bentonite of 30 to 40 wt.%, the thermoplastic resin of 30 to 35 wt.%, the water absorptive resin of 5 to 15 wt.% and the plasticizer of 15 to 20 wt.% are respectively compounded to mold the water stop material. It is heated at a high temperature after the mixture of the thermoplastic resin and the plasticizer, and the thermoplastic resin heated at the high temperature is compounded with other main ingredients to mold the water stop material.
