METHOD OF PLASTIC DRAINAGE CONSTRUCTION AND DEVICE FOR METHOD IMPLEMENTATION Russian patent published in 2009 - IPC E02B11/00 E02F5/10 

FIELD: construction.

SUBSTANCE: invention concerns drainage construction and can be applied in obtaining drain and collection network mainly for ground water level above drainage laying line. Method of plastic drainage construction involves trench development by reverse-rotation flail of narrow-trench ditching machine moving between walls of trench and ditching machine tank for developed soil collection for covering of drain pipe inserted into the trench over guide line. Drain pipe with synthetic filter is inserted into guide line with plastic-elastic screen wrap not wider and the pipe perimetre and attached to absorbing well along tangent line to the well axis. Absorbing well is laid onto trench bottom with a screen unfolded above it in bed with width equal to diametre of drain pipe with synthetic filter and depth not exceeding pipe diametre. Device for plastic drainage construction includes basic machine, active tool mounted on a frame, drain pipe chute with guide line of alternate cross-section, drain pipe supply tank in the form of box formed by two transverse and two lengthwise vertical walls, with front cutting edge and ploughshare. Additional frame connected by upper part to active tool frame and by bottom part to tank and profiled cutter and featuring deflector extensions mounted along its height at 3÷4° angle to horizon is mounted between active tool and tank, parallel to ascending chain of active tool. Top part of drain pipe guide features constant diametre for passage of drain pipe with filter and screen and is coupled with profiled ploughshare through mouth part.

EFFECT: enhanced efficiency and quality of brickwork, reliability of drain operation, eliminated necessity of using drain fill.
