METHOD OF ORGANIZATION OF DRAINAGE Russian patent published in 2018 - IPC E01F5/00 

FIELD: construction.

SUBSTANCE: invention relates to the construction of railways and highways and can be used to drain water from the roadbed and other bulk structures. Method of constructing a drainage structure includes the formation of a channel with the subsequent laying of a protective coating along the bed of a flexible material with the formation of projections of the bed bottom. Flat polyethylene flexible material is used, which is covered from above with resilient rods and/or fibers protruding in the form of a brush, fixed rigidly with a flexible polyethylene material. In this case, the latter with elastic rods and/or fibers is laid along the perimeter of the bottom and walls along the length of the channel alternating consistently equal separate bands. Moreover, the edges along the perimeter of the flexible polyethylene material, which are laid along the profile of the surface of the bottom and walls, are fixed with plates and made of metal group including aluminum and tin.

EFFECT: reduction of labour-intensity of the work.
