摘要
The invention relates to an arrangement for damming water and also for draining away the volume of water above a certain level in a vegetation-bearing stratum. Arrangements of this type normally have on the base consisting, for example, of concrete, a sealing layer and on top of this a root protection sheet. In addition, the base has an inlet channel for the water. The primary purpose of the arrangement is to ensure that the water located between the sealing layer and the root protection sheet is carried away into the inlet channel. The arrangement also consists of a pipe socket set with clearance in the inlet channel and which is provided externally with a plate-like flange next to its upper edge and, additionally, with a water-damming pipe arranged at an adjustable height in the pipe socket, the exterior of this pipe being sealed in respect of the interior of the pipe socket. The plate-like flange of the pipe socket is joined so as to be sealed in respect of the roots to the edge region of the root protection sheet surrounding a drainage hole in the root protection sheet.
