TEMPORARY SEWAGE RELAY PUMPING STATION/WELL CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a temporary sewage pumping station/well construction method with which a concrete wall buried underground of a sewage relay pumping station is thickened for seismic strengthening.;SOLUTION: A temporary sewage relay pumping station/well construction method includes a work stage 1, a work stage 2 and a work stage 3. On the work stage 1, downflow of sewage to a first water channel 16 and a second water channel 17 is shut off, a bypass pipe 18 is connected to and an assembly type water tank 19 is installed at a side of the second water channel 17 and then, thickening work at a side of the first water channel 16 is performed. On the work stage 2, after the thickening work of the first water channel 16 is completed, a bypass pipe 18 is connected to and an assembly type water tank 19 is installed at a side of the first water channel 16, the bypass pipe 18 and the assembly type water tank 19 at the side of the second water channel 17 are removed, and thickening work of the second water channel 17 is performed. On the work stage 3, after the thickening work of the second water channel 17 is completed, the bypass pipe 18 and the assembly type water tank 19 at the side of the first water channel 16 are removed.;COPYRIGHT: (C)2014,JPO&INPIT
