SLOPE PROTECTION METHOD AND A SET OF SOIL ANCHORS FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC E02D17/20 

FIELD: geology.

SUBSTANCE: protective method and device designed to prevent landslide and erosion processes, which include soil anchors. A method for protecting a slope from erosion and landslide processes is characterized in that protection is carried out by fixing the slope soil using a protective structure element, a set of connecting rods, including anchor rods and anchor bars, and a set of soil self-expanding anchors, consisting of at least two groups formed in advance. The element of the protective structure is installed on the slope and, by means of a set of connecting rods, is mechanically connected to the soil self-expanding anchors, which are immersed in the soil of the slope in its natural state. A set of soil self-expanding anchors and a set of connecting rods are formed based on in situ determined soil parameters in the solid of a fixed slope, where a set of soil self-expanding anchors is formed by selecting soil self-expanding anchors in at least two parameters, one of which reflects the permissible load capacity, the other reflects the constructive feature of self-expanding anchors included in the set, the number of self-expanding anchors in the set is determined from the condition of sufficiency for fixing the element of the protective structure. The composition of the set of connecting rods is adjusted depending on the type of protective structure and the mechanical connection of the set of connecting rods with a ground self-expanding anchor and a protective structure.

EFFECT: reducing the time spent on the installation of protective devices with a significant reduction in the volume of soil moved when arranging protective devices for slopes.
