METHOD TO INSTALL WIRE ANCHORS Russian patent published in 2015 - IPC E02D17/20 

FIELD: construction.

SUBSTANCE: invention relates to nature conservation arrangement of mountain and foothills landscapes and may be used as anchors for anti-erosion and anti-landslide structures, and also in case of emergencies. The method to install wire anchors is characterised by the fact that a device is screwed into soil for the required depth, and the device comprises doubled hollow pipes, the outer of which comprises evenly arranged ledges of permanent rectangular cross section, rigidly fixed along the side cylindrical surface along the helical line with permanent pitch. After the device reaches the required depth, the inner pipe together with cohesive soil is withdrawn from the outer pipe to form hollow space, and soil is removed from it. Then a wire anchor is inserted into the produced hollow space of the outer pipe, with a cylindrical head, and backfilling is done with soil for height h with subsequent putting of cylindrical attachments onto the anchor wire, and the outer pipe is screwed out with the help of a handle as the anchor is grown.

EFFECT: increased efficiency and reliability of installation of wire anchors on slopes and ravines.
