Method and device for connecting an watertight plastic membrane and a channel

摘要

The channel (1) for conducting water through a shaft (10) sunk into ground takes the form of a ready-made channel body (3) which is joined watertight to the water inlet and outlet pipes (5, 7), with its end zones (15, 16) fixed in the openings (19, 20) in the shaft wall and sealed against water.
