LANDSLIDE PROTECTION STRUCTURE OF COMBINED DESIGN Russian patent published in 2014 - IPC E02B3/12 E02D17/20 

FIELD: construction.

SUBSTANCE: in a landslide protection structure on the basis of a collapsed slope there is a bed of flexible mats, which are made of tight rows of light fascines laid normally to the line of slope inclination. On top of flexible mats there is a fixture of gabion mats with drainage devices made of light fascines and perforated pipes laid by alternating rows and wrapped into a gabion net. Flexible mats in the base and gabion mats on top of them are connected to each other by a galvanised metal wire with diameter of 2.5-3 mm. A drainage prism from rock filling is arranged along the foot of the collapsed slope. Above the slope fixture from flexible and gabion mats there is an additional fixture with low inclination from similar gabion mats with drainage devices. Gabion mats of slope and additional fixtures are tightly tied with the help of reinforcement wire and are fixed to reinforced concrete anchors arranged at a certain distance from each other in stable soil behind collapsed massif of the slope.

EFFECT: reliable protection of different objects located under slopes, where landslides and collapses of soil massifs are possible.
