WATER SUPPLY STRUCTURE Russian patent published in 2022 - IPC E01F5/00 E02D15/00 

FIELD: road construction.

SUBSTANCE: invention relates to the field of road construction and can be used in the construction of roads to ensure the passage of water through the body of the subgrade. The water supply structure contains a pipe, which in cross section has an ovoid profile, the smaller radius of which is located in the upper part of the pipe, and the lower part, which has a larger radius, is installed on a natural base with technogenic preparation. On the upper half ring of the ovoid pipe, along the entire perimeter from the outside, on both sides, symmetrically relative to each other and made of two-layer with an anti-friction coating of the inner contacting sides, cuts of film material are located. Each cut is formed from a single part, folded in half and has two free ends led to the adjacent half of the pipe to a length equal to the radius of the larger ovoid circumference. The bending point of the film material cuts is located in the upper layer of the natural base with technogenic preparation. The upper surface of the cuts of the film material, which is in contact with the backfill, has at least two folds located at an equal distance from each other and with a length equal to twice the calculated settlement of the backfill soil.

EFFECT: improving the reliability of the structure.
