DRAINAGE CONSTRUCTION METHOD ON BUSHY WATERLOGGED LANDS Russian patent published in 2022 - IPC E02B11/00 A01B79/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture and will find application when unused waterlogged lands overgrown with shrubs are returned to agricultural circulation. The method consists in the fact that before laying the drainage along the route of the design trench and the edged support strips, the ground shrub vegetation is cut and crushed together with the soil layer of 5-7 cm, the drained support strips are leveled for the passage of equipment, while simultaneously filling the surfaces of the design trench and the edges with the crushed mass, further along the backfill, the root wood, plant and root residues are crushed along with the soil. A trench is torn off along a loosened track and a mixture of crushed ground and root wood is used as a structure former of the soil extracted during trench excavation. The laid drainage pipe is sprinkled with a filter layer of crushed ground wood, plant and root residues with soil inclusions, after which the trench is covered with previously excavated structured soil and the root wood of the stripped strips is crushed. Application of the proposed method makes it possible to use shredded shrub vegetation cut off when clearing the drain route, together with plant and root residues and soil inclusions, for structuring the soil of the drainage pipe powder and backfilling the trench, which significantly increases the water intake capacity of the drainage.

EFFECT: sequential processing of the drainage strips ensures the passage of equipment on waterlogged soils with low bearing capacity, which improves the productivity and quality of drainage laying.
