E02B11/00—Drainage of soil, e.g. for agricultural purposes
Abstract
Side walls (9, 10) extend to the vicinity of a top side of a pipe. Evenly spaced plugs (2) are inserted in the bottom of the pipe and grip the pipe at the lower end of a rise space. At the upper end is a perforating component (7) which can pass through the top side of the pipe (6). - Under the perforating component is a seal (8). The perforator is pressed through the pipe and then springs backwards and is sealed, with the plugs in position. This ensures that the two halves of the pipe are not pressed against one another and that the rise space does not bend to one side or the other. The plugs prevent water flow in the rise space longitudinal direction, which is essential for the long-time function of the drain pipe. (Dwg.No.2)
