COMPOSITE STRUCTURE AVALANCHE BREAKER Russian patent published in 2014 - IPC E01F7/04 

FIELD: process engineering.

SUBSTANCE: proposed structure consists of converging walls making an acute angle at vertex and features flexible and combine design. It is made up of triangular soil embankment with side slopes. The latter are secured by gabion revetments over the entire length of breaker to bed. Reinforced concrete girder frame is arranged above said gabion revetments laid from breaker top to both sides. Said girder frame is made on bed boards and top boards interconnected by grillage arranged in slope line at define spacing. Channel or other metal section is laid on its rib in the line of breaker angle vortex to bed board and built in on both side the concrete to three fourth of its height. Metal girder frames composed by vertical grates and buttress rods rigidly secured to anchors are laid above the ridge reinforced concrete boards. Avalanche breaker is shaped to triangle with vortex angle of 80-90 degrees. Note here that reinforced concrete girder frame arranged above said gabion revetments features length making at least two thirds of slope sidewalls of the structure. Propose breakers can be efficiently used at the most dangerous zones of upland infrastructures.

EFFECT: higher efficiency and reliability.
