Abstract (en)

The chamber consists of a hollow body (1) designed to be installed with its axis set vertically, open at the top and having a base (6) with a connecting channel for the pipes and shoulders on either side joined to the body (1), at least one of the shoulders having a supporting leg (8) beneath it. The supporting legs have holes through them, are hollow when viewed from the inside of the chamber and are designed to keep the chamber upright while it is standing on a horizontal surface. The holes are designed to allow concrete to pass through when the chamber is fixed in place on a foundation (23) before the excavation for it is back-filled with soil.
