堤防の漏水抑止装置及び方法

Abstract

<P>PROBLEM TO BE SOLVED: To almost completely prevent the leakage of water from piping caused by the pressure of water stored in a bag body 8 since a pipe 20 blocks an erosion groove even if the erosion groove is formed at the ground 7 due to an effect that the pipe 20 is driven into the ground 7 by being wound around a water leakage portion 6, and the water leaking from the water leakage portion 6 an surely be guided into the bag body 8. <P>SOLUTION: This water leakage preventing device has the flexible, watertight, and flat bag body 8 having an intake 10 at a bottom 9 and an openable and closable opening 12 in an upper part 11, an annular packing 14 provided on an upper face of the intake 10 and around it at the bottom 9, and the pipe 20 driven into the ground 7 by passing through the packing 14 and the intake 10 of the bag body 8. The packing 14 is brought into pressure-contact with the bottom 9 of the bag body 8 by a pressing means. <P>COPYRIGHT: (C)2011,JPO&amp;INPIT
