DRAINAGE ABSORBER-WELL FOR RECEIVING AND DISCHARGING SURFACE WATER Russian patent published in 2020 - IPC E02B11/00 

FIELD: agriculture.

SUBSTANCE: invention relates to devices for reception and treatment of surface water from suspensions and discharge of clarified waters and can be used in agriculture of non-chernozem zone during drying of heavy mineral soils for removal of surface water and draining of drain gullies, as well as in erosion control of surface runoff on catena. Drainage well-absorber is placed in the closed water catchment area reduction and includes receiving chamber 1 connected to the larger sediment precaution chamber 2. Collector 4 having gate valve 5 is connected to pit 3. Bottom of settling pre-chamber 2 has a slope towards formed in the bottom of nanoparticulate sump 3. Drainwell absorber comprises vertical partitions 9 and 10. In lower part of vertical partitions 9 and 10 are fixed L-shaped caps 11 and 12, shelf of which is directed towards settling pre-chamber 2. Partitions 9 and 10 divide well-absorber into receiving chamber 1 and settling sedimentation pre-chamber 2. Side wall of receiving chamber 1 in upper part has located outlet hole 13 for overflow of clean water into pipeline 14 (or consumer), which end is connected to manifold 4 from outside. Vertical partitions 9 and 10 are fixed so that between their lower edge with L-shaped aprons 11 and 12 to side of bottom 7 of slope 6 slit hole is formed for water passage from receiving chamber 1 into settling pre-chamber 2. Sediment of small deposits will be supplied to header 4 with gate valve 5, and clean water is poured into pipeline 14 and then enters collector 4 after gate valve 5. Protective coating in form of rigid metal grid 15 of dome shape is installed directly on cover 8 above receiving chamber 1. Dome-like shape of dome 15 is fixed by one end with hinge 16 to cover 8, and its free end has handle 18 serving to hold grate 15 in the vertical position when receiving chamber 1 is opened. Lattice 15 and covers 8 and 19 have black colour. Lattice 15 of dome-shaped shape is located slightly above cover 8, protects receiving chamber 1 from ingress of various large objects and debris, excludes blockage and clogging by soil, brought from incoming surface water. Structure of the construction is aimed at ensuring efficiency of operation and increasing crop capacity of agricultural crops.

EFFECT: provides maximum security of the structure, its reliability and durability.
