METHOD FOR CONSTRUCTION OF LANDSLIDE PROTECTION STRUCTURE OF BIOPOSITIVE Russian patent published in 2016 - IPC E02B3/12 E02D17/20 

FIELD: construction.

SUBSTANCE: invention relates to hydrotechnical and nature protection construction and can be used for protection of roads, coastal areas and other objects from landslides and rockfalls ground arrays. Method involves placing retaining attachment of flexible and gabion revetments, interconnected and secured to anchors, and drain prism 2 of stone. Drain prism 2 is made of reinforced gabions 3 arranged in three layers and more with deepening below bottom slope and line of possible collapse of road slope massif. Gabions 3 have length of 2-2.5 m and width 0.5-1.0 m and height of 0.5-1.0 m of reinforcing carcass Al diameter 12-14 mm, zinc-plated grid 6 and stone aggregate 7. First and second layers gabions 3 is laid with deepening in base below bottom slope, normally to its line and road axis. Third layer of gabions 3 is laid on top and lower layers in the middle and along the line of bottom slope. High attachment above the drain of the prism is made from said gabion revetments laid stepwise 4 with drain devices and flexible reinforcing soil body screens 11 of fibre-glass materials. Gabion mattresses 4 is made of light fascines and perforated tubes laid alternating rows and wrapped in gabion sieve, to which at base 4 and revetments over the entire length is attached flexible reinforcing mesh 11 of fibre-glass materials, width in 3 times and more larger width revetments 4. Flexible reinforcing fiberglass mesh 11 gabion revetments 4 stepwise cut in demolished 1 slope soil body throughout its height, so that depth of indentations investigation reaches stable soil beyond the line of possible collapse of road slope massif. Higher stability of caved ground massif slope.

EFFECT: landslide protection structure biopositive design, raised to the disclosed method can be used for engineering protection and economic facilities against possible landslides and rockfalls Bank ground arrays on mine and submontane, hard-to-reach areas, when the height of the damaged soil mass does not exceed 12-15 metres.
