CLEANING DEVICE AND CLEANING METHOD FOR WATER INTRODUCING GUTTER IN UNDERGROUND STRUCTURE

摘要

PROBLEM TO BE SOLVED: To easily remove a deposit inside of a water introducing gutter without requiring a cleaning scaffold by arranging a hollow strainer-like pipe formed with a large number of holes in a side surface in a leakage water draining water introducing gutter installed in a water leakage place of an underground structure, and cleaning the inside of the water introducing gutter with wash water blowing out of these holes. ;SOLUTION: A water introducing gutter 10 composed of vinyl chloride is arranged in a water introducing groove 8 formed in a construction joint part 11 of a concrete skeleton 1 of a tunnel, and both end parts are fixed to the concrete skeleton 1 by an anchor bolt 14 via a shock absorbing material 13 such as rubber. A hollow strainer- like pipe 20 being composed of a flexible resin material such as plastic and forming a large number of holes 18 in a side surface is arranged in the water introducing gutter 10. A pair of installing pieces 17 are arranged in this pipe 20 by an integral mold to constitute a pipe unit 16. High pressure wash water is supplied from a cleaning hole inserted into a hollow part 19 of the pipe 20 to be blown out of a large number of holes 18 in the side surface of the pipe 20 to clean the inside of the water introducing gutter 10.;COPYRIGHT: (C)2000,JPO
