PLASTIC DRAIN SETTLING WELL Russian patent published in 2015 - IPC E02B11/00 

FIELD: agriculture.

SUBSTANCE: invention relates to reclamation of lands and can be used for land drainage with closed drainage and maintenance of constructed drainage systems. At first the plastic drainage wells can be used on small drainage systems of plastic (farms, garden plots, in the setting of near-wall drainage, drainage of urban territories and territories of rural settlements). The plastic drainage settling well comprises a mine 7, a hatch cover 8, a bottom settler 1, water supply pipes 9, and a water removal pipe 10, located above the bottom of the drain well. The well bottom is provided with an annular projection 2 formed on its inner surface at a height of not less than 30 cm from the bottom with the ability of mounting on it of a removable plastic tray 3 with a rim, on which a handle 5 is hingedly attached with the ability to pick it up with the rod hook to lift the tray with sediment on soil surface 12. The tray 3 in its upper part is provided with holes 6 evenly distributed on the lateral surface for discharging the clarified settled water. The pipes entering in the well 9 and a pipe 10 exiting from it are connected to the mine 7 at differential levels of the pipe top of 5 cm.

EFFECT: proposed plastic drainage settling well with little labour intensity can be cleared of sediment, which ensures its reliable operation and regulatory effective period of the drainage system of the plastic materials.
