摘要

The collector tub for polluting chemicals has bottom plates of metal, pref. refined steel secured, e.g. by gluing, to a solid base, such as concrete, and welded together on abutments. Perforated test pipes are mounted at the joints. A further sealing cover layer is mounted mon the one glued to the base, and comprises metal plates (2), typically of refined steel, welded together along their butting edges (6). Bosses (100) on the bottom (1) and/or cover plates protrude towardsma each other, forming a hollow space (9) in between. The two layers are welded together along their peripheral edges to form a sealed jOinl. ADVANTAGE - Improved safety and monitoring for leaks.
