Abstract: Slotted channels with coverings (10) are known for discharging surface water into a channel. The covering has at least one horizontal sheet-metal portion (13) and two vertical sheet-metal portions (11, 12) which are connected to one another via connection devices and have a slot (14) between one another for discharging liquid, for example surface water, into the channel body. In order to allow a particularly complete discharge of water, it is proposed that the horizontal sheet-metal portion (13) comprises drip devices (15) which are mounted and designed in such a way that water running along on an underside of the horizontal sheet-metal portion (13) drips into the channel body.

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.

Abstract: Rails for drainage channels or manholes are known on which a cover of a channel or of a manhole can be placed. The rail has a horizontal bearing surface (10) extending in a longitudinal direction of the drainage channel or of the manhole and, substantially perpendicular to this bearing face, a rail edge (11) on the inner surface (12) of which the cover can be placed and on the outer surface (13) of which a surface covering can be applied. To increase the strength, it is proposed that the bearing surface (10) and/or the inner surface (12) and/or the outer surface (13) is/are provided with beads (20, 22, 23) over the entire length of the rail (1).

Abstract: A stable and variable design of a drainage structure includes a drainage body (11) and a cover (20). The cover (20) has engagement devices (13, 13?; 14, 14?; 23, 23?) when seen in a longitudinal direction of the drainage body (11), whereby the cover connects upper edges (12, 12?) of the drainage body (11) to one another transversely to the longitudinal direction in a tension-resistant manner over the entire length of the drainage body. In order to allow the use of different covers (20) for different loads, for example while using the same drainage body (11), two types of engagement devices (13, 13?; 14, 14?) are provided on the drainage body.

Abstract: The aim of the invention is to allow a simultaneously stable and variable design of a drainage structure consisting of a drainage body (11) and a cover (20). This is achieved in that the drainage body (11) and the cover (20) continuously have engagement devices (13, 13?; 14, 14?; 23, 23?) when seen in a longitudinal direction of the drainage body (11), whereby the cover connects upper edges (12, 12?) of the drainage body (11) to one another transversely to the longitudinal direction in a tension-resistant manner over the entire length of the drainage body. In order to allow the use of different covers (20) for different loads for example while using the same drainage body (11), two types of engagement devices (13, 13?; 14, 14?) are provided on the drainage body.
