METHOD OF IMPROVING AND/OR REPAIRING POOL BOTTOM MADE OF METAL INCLUDING WATER DISCHARGING LINE

摘要

PURPOSE:To shorten the period of improvement and/or repair by removing an existing water discharging line in the vicinity of the end section of an existing pool bottom, advancing and positioning a synthetic resin pipe and penetrating the communicating hole of a pit bottom recessed to a synthetic-resin finishing panel to the pipe. CONSTITUTION:A section near the end section of an existing pool bottom (a) is drilled and an existing water discharging line C in the ground is cut, and a water discharging line on the downstream side is drawn. A pipe 6 made of a synthetic resin is inserted and positioned by utilizing a drilled port drilled through a removal process. A surface finishing panel 1 made of the synthetic resin such as FRP is laid onto the existing pool bottom (a) including a drainage pit 3' through a spacer 2, and the riser section 6' of the pipe 6 is penetrated automatically into the communicating port 8 of a new pit projected from the panel 1. A clearance between the mutual sections of the panels 1 is blocked and fixed by a lining material. Accordingly, the term of work is shortened, and cost can be reduced.
