摘要： PURPOSE: To assuredly prevent leakage of water from a juncture side of a water-barrier sheet by using, as an adhesive, a water absorbing adhesive which contains a water absorbing resin. CONSTITUTION: A water absorbing adhesive which contains a water absorbing resin is used as an adhesive. For the adhesive, a water absorbing adhesive comprising the water absorbing resin and a rubber adhesive or a thermoplastic resin adhesive is used. The water absorbing resin of 20-200 pts.wt. is preferable based on 100 pts.wt. of rubber component or thermoplastic resin component. For the rubber adhesive, a self-vulcanizing rubber adhesive is preferable. For the thermoplastic resin adhesive, a polypropylene, a polyethylene, and an EVA are preferable. That is, edge parts of water-barrier sheets 10A and 10B consisting of fiber sheet layers 12 and water-barrier outside face layers 11 layered on top and bottom faces of the fiber sheet layers 12 are superposed. In between the water-barrier sheets, a sheet formed of the adhesive is inserted so as to be an adhesive layer 13, and it is pressed by a roller. Next, the adhering parts are stitched together by a sewing thread 14.

CONSTITUTION:A directional neutron moisture meter 4 is contained in cylindrical strut 6 for linking upper and lower air packers 5a and 5b, and the directivity is controlled with a directivity controller 15. Air is sent and discharged with a packer operating device 7 into and out of the packers 5a and 5b. The packers are brought into contact with a strainer pipe 2 with pressure, and the moisture meter 4 is fixed. The moisture meter 4 can be moved by the contraction with the pipe 2. The moisture meter 4 is connected to a digital count-rate meter 8, and the concentration analysis of tracer 9 in the moisture meter 4 is performed. A hole for discharging the tracer 9 is provided at the lower part of the packer 5a and coupled with a tracer injecting device 10. A T pipe line 11 is provided at the outlet port of the device 10 and connected to a vacuum pump 13 through an underground-water sampling bottle 12. At the time of the sampling of the underground water and the time of the flow measurement, the pipe line is changed to the side of the pump 13 and the side of the device with a directional control valve.
