Abstract

A safety valve (4) enables the draining conduit to be pressurised forwards. The other side of the draining conduit is plugged with a pipe-plugging balloon so that the conduit can be pressurised with compressed air, causing its pores to open to the ground, so that it can against drain the area with open pores.
