EARTHEN STRUCTURE ON WEAK SOILS Russian patent published in 2018 - IPC E02D17/18 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction and can be used in the construction and reconstruction of linear structures on weak soils. Earthen structure on weak soils contains the body of the embankment and a reinforcing device, which is a top cloth made of synthetic nonwoven material (SNM) and two fastening devices, each of which includes an upper cylindrical steel roller with a pair of ropes made of steel ropes, the upper cylindrical steel roller of each mounting device is laid on the canvas of the body of the earthen structure of the embankment on each side of the deforming section, the lower ends of the foundation are fixed in strong soils of the earthen structure outside the deforming section, the upper panel of the SNM is stretched onto the above-mentioned upper rollers of each fastening device in the form of a closed tape. In the reinforcing device additionally introduced the bottom panel of synthetic non-woven material (SNM), each fastening device is additionally equipped with a lower cylindrical steel roller, with the lower cylindrical steel roller of said fastening device being laid at the base of the embankment body of the earthen structure on each side of the deforming section for its entire length. Axes of the upper and lower steel rollers of each fastening device are rigidly interconnected to form a frame. Upper ends of the braces are connected to the axis of the lower steel roller of each fixing device on its two sides. Bottom panel of the SNM is stretched on the lower rollers of each fixing device in the form of a closed tape.

EFFECT: technical result consists in increasing the stability of the earthen structure by increasing the carrying capacity of the foundation soils when exposed to a moving and constant static load by increasing the duration of the holding effect of the reinforcing device.
