Abstract

A pair of webs each extending over a large area and disposed in a vertical orientation in a suspension are interconnected by a pair of telescoping tubes attached to juxtaposed edges of the respective barrier webs. Material of the suspension is removed from the space within the inner tube to provide a hydraulic trap for liquid entering the connection or coupling between the two tubes. A device is provided for inspecting the level of the liquid collected in the hydraulic trap or for removing the collected liquid. The barrier webs are advantageously made of synthetic resin material such as high-density polyethylene.
