Abstract

Trench drains are hollow or grid-like bodies which can be installed in the ground and are intended to receive precipitated surface water and slowly dissipate it into the ground or to store the water. These hollow or grid-like bodies are constructed from individual drainage bodies which must be firmly connected together. Drainage body connecting elements are proposed for connecting drainage bodies, which comprise two pegs which are connected via a web and can each be inserted in a receiving orifice of a drainage body so the two drainage bodies can be connected together via the web.
