During the course of another route, it is about 20 days away from the river.

The purpose of the invention is to increase the efficiency of the drainage device.

FIG. 1 shows a drainage device, a cross-section; fig 2 is the same, top view.

Drena; (The device consists of a drainage trench 1, along the bottom of which a drainage 2 is laid. At the corners of trench 1 there are half-open mole 3, covered with rolls 4 made on the bottom of the trench. Semi-open mole 3 are connected by regular cross-section filtering

strips 5 with the drainage 2 located along the axis of the trench bottom,

Drainage device operates as follows.

Trenching is not always horizontally permeable. In most cases, especially in the initial peribd, drainage water flows into the closed trench 1 along the fine grooves formed on its walls. This path is made by both surface soil and ground water coming from the surrounding untouched soil through the walls of trench I. Poorly permeable trench is not damaged allows the drainage waters to penetrate directly to the drape 2, and they, down the walls, first fall into the half-open mole 3, located at the corners of the trench 1, and then along the transverse filter strips 5 from the filter conductive material - to Dren 2 and are withdrawn into receiving waters.
