In the pipe there is a conduit (5) connected to a liquid mortar supply and coupled with a shut-off valve (8) fitted to the end of the pipe. Once the bearing layer is reached, the pipe is withdrawn from the earth as the shut-off valve is opened and the liquid mortar is fed in. A reinforcement may then be introduced.</p> |
