METHOD TO ERECT COASTAL SUPPORT FROM FASCINES OF BIOPOSITIVE DESIGN

摘要

FIELD: construction.;SUBSTANCE: method includes laying of light and heavy fascines in layers along a bank slope 2. Heavy fascines 1 are laid in longitudinal and transverse strips to form square or rectangular cells of different size from 1 to 2.5 m. Heavy fascines 1 are connected to each other by means of metal stainless nets and wires. Inside the cells into the base they lay and attach a polymer net 4 to heavy fascines 1, on top of which in one layer they lay light fascines 3 in dense layers, tightened on top with a gabion net 5. Additionally in the base of the slope 2 at a certain distance from each other there are gabion mats 6 of prismatic form laid and attached to heavy fascines 1 of slope fixation. On top of gabion mats 6 they arrange a reinforced latticed frame 8 of segment shape and attach to rectangular rings 9, wrapped around gabion mats 6 at the distance from each other. The reinforced frame 8 with the help of ropes or reinforcement wires 10 are in some places fixed to anchors 11, which are arranged in the slope 2 above the fixture and at the distance from each other. The invention is designed for engineering and environmental protection of coastal areas of rivers in their piedmont and flat areas, where average speeds of flood flows do not exceed 2.5-3.0 m/s. This method may be most efficiently used in flat and hard-to-access areas of small rivers.;EFFECT: higher efficiency of operation and reduced material intensity of a slope fixture.;2 cl, 6 dwg
