Abstract: Disclosed is a drainage system (1) comprising: at least one water receiving unit (20) having: a water receptacle (22) for receiving water from an adjoining surface of an upper stratum; and at least one drainage unit comprising: a body; wherein: the water receptacle (22) can be integrated into the upper stratum; the drainage unit can be provided and oriented, at least in part, in a central stratum at a distance under the surface, with respect to its uppermost face, such that water flowing out of the water receiving unit (20) can flow into the drainage unit through a connection between the water receptacle (22) and the body; and the connection can be maintained irrespective of a change in this distance. Also disclosed are drainage units and methods.

Abstract: According to different embodiments, a channel-retaining device (200) can comprise: a retaining holder (102), which has a first coupling region (102k) and a retaining region (102a) for retaining a drainage channel extending in a direction; a retaining socket (104), which has a second coupling region (104k); wherein the first coupling region (102k) and the second coupling region (104k) form, when joined together, a joint (106), which provides the retaining holder (102) and the retaining socket (104) with a rotational degree of freedom (111) relative to each other in the direction; a locking device (108), which is designed to block the rotational degree freedom (111) when the locking device is placed in a first state, so that the retaining holder (102) and the retaining socket (104) are locked to each other, and designed to release the rotational degree freedom (111) when the locking device is placed in a second state, so that the retaining holder (102) and the retaining socket (104) can be moved relative to eac

Abstract: A drainage system (1) comprising: at least one water receiving unit (20) having: a water receptacle (22) for receiving water from an adjoining surface; a first neck piece (24) which can be connected to the water receptacle (22) and provided such that water can flow out of the water receiving unit (20) through an opening (26) of the first neck piece (24); and at least one water drainage unit (40) for draining the water, comprising: a pipe body (42); and a first opening (46b), provided on the pipe body (42), for receiving the water in said pipe body (42); wherein: the water drainage unit (40) can be provided and oriented under the surface such j that the opening (26) of the first neck piece (24) and the first opening (46b) of the pipe body (42) can be connected and the water flowing out of the water receiving unit (20) can flow into the water drainage unit (40). Also disclosed are drainage units and methods.

Abstract: The invention relates to a drain trench body having base plates (11, 12), between which columns (13) are arranged vertically. The drain trench body comprises side walls (14) which are connected to the base plates (11, 12). The side walls (14) and the base plates (11, 12) have first and second locking elements (15, 16) which are in engagement with each other. The locking elements (15, 16) are movable relative to one another in the height direction along the longitudinal axis of the columns (13). The invention further relates to a center plate (20) for a drain trench 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.
