INSTITUTION STRUCTURE OF SILT PROTECTOR OF INTAKE TOWER FOR TAP PIPED WATER

摘要

An installation structure of a silt protector of an intake tower for the waterworks is provided to prevent the inflow of floating materials fundamentally. Inside and outside slip pipes(10,10a) are fixed erectly from every direction between a lower basic block(13) and an intake tower(100). An inside net sieve(20) is moved up and down by a control member at the inside slip pipe and prevents the inflow of foreign substances toward an absorbing pipe(101). An outside protection cover(30) is moved up and down by the control member at the outside slip pipe. The control member ascends and descends the inside net sieve and the outside protection cover according to the height of the water level.
