PIPE DRAINING HORIZONTAL SHARED FILTER WITH THE LARGE DUTY CYCLE Russian patent published in 2018 - IPC E03B3/18 E21B43/08 

FIELD: construction.

SUBSTANCE: invention relates to the field of reclamation, transport, housing and communal, hydraulic engineering for horizontal drainage equipment. Device includes a water intake frame made of basalt plastic or fiberglass rods, mounted along the generatrix along the axis of the filter and connected by set ring shaped stiffnesses, overlapped on the external surface of geotextile, which is based on basalt fiber. Connection of the links to the filter column is carried out with the aid of curly stiffening rings of a trapezoidal cross section with a doubled number of access openings, that allow the rods of the connecting links to pass through. Coating of the filter cork from the geotextile at the joint site is carried out lapping without the use of adhesive compositions with the formation of a continuous front for the intake of drainage water.

EFFECT: filtration efficiency is increased due to the increase in the reception front of drainage waters, the labor intensity of manufacturing is reduced.
