REINFORCED RUBBLE CONCRETE FIXING Russian patent published in 2003 - IPC

FIELD: water-development works, bank fixing structures in washed-out beds of rivers, canals and other objects. SUBSTANCE: reinforced rubble concrete fixing is made up of reinforced rubble concrete blocks divided in plan by structural-functional joints into squares or rectangles intercoupled on all four sides with heavily deformed net and formed by layer-by-layer alternation of densely laid stones and high-strength mortar into which this net is laid. Dimensions of fractions of stones grow from lower layer to upper layer and dimensions of cells of net do not exceed dimensions of fractions of stones and these dimensions also grow from lower layer to upper layer. Number of layers of stones can be more than 2 and number of layers of net is more than one. Reinforced rubble concrete fixing can come in the form of invariable reinforced rubble concrete frame divided by length and possessing rectangular or square cells on which bottom antisuffosion arrangement in the form of filter on which cobble stones are laid is put. Rectangular or square cells of reinforced rubble concrete frame are joined in corners by means of braces and have triangular shape in plan along diagonal in plane of arrangement of net. EFFECT: reliable operation of fixing under action of vibration- oscillatory loads and loads with alternating directions. 3 cl, 9 dwg
