CLOGGING PREVENTION APPARATUS FOR WATER COLLECTING PIPE FOR GROUND WATER REMOVAL FACILITY

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive apparatus for preventing the clogging of a water collecting pipe for a groundwater removal facility which can quickly remove clogging substances generated in the water collecting pipe to the land surface and prevent clogging of the water collecting pipe without using a complicated mechanical structure or power.;SOLUTION: The clogging prevention apparatus comprises a water collecting pipe 2 whose one end is closed and the other end is opened and which is downward slantingly buried at a position lower than the groundwater surface of a ground 1 while the opened end being projected out of the soil wall face 3. The strainers 4 are bored on the water collecting pipe, an approximately S-shaped extension pipe 7 is connected to the projected opened end in such a manner that once stored groundwater from the water collecting pipe 2 can be discharged by function of a siphon, and a ventilation pipe 10 is installed toward the extension pipe from the vicinity of the connection part of the extension pipe and the water collecting pipe.;COPYRIGHT: (C)2004,JPO
