LANDSLIDE PROTECTION STRUCTURE OF BIOPOSITIVE DESIGN 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. Landslide protection structure contains attachment panels of flexible and gabion revetments joined to each other and attached to the reinforced concrete anchors, and drain prism of stone, arranged along the bottom of slope. 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 the length of 2-2, 5 m and width 0.5 -1.0 m and height of 0.5 m -1.0 of reinforcing carcass A1 diameter 12-14 mm, zinc-plated grid 6 and stone aggregate 7. First and second layers gabions 3 are laid with deepening in base below bottom slope, normally to its line and road axis. Third layer 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 prism 2 is made of stepwise laid gabion revetments 4 with drain devices and flexible reinforcing soil body screens 11 of fibre-glass materials. Gabion mattresses 4 are 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 are attached flexible reinforcing mesh 11, width in 3 times and more larger width revetments 4. Flexible reinforcing mesh 11 gabion revetments 4 in steps are embedded 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. High fixation of stepwise laid gabion revetments 4 with drain devices and flexible reinforcing soil body 1 screens 11 of fibre-glass materials forms reinforced ground design providing high stability of caved ground massif slope.

EFFECT: landslide protection structure biopositive structure 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.
