METHOD FOR ERECTION OF SLOPE SUPPORT FROM FASCINES OF BIOPOSITIVE DESIGN

摘要

FIELD: construction. ^ SUBSTANCE: method for erection of slop support of biopositive design includes layering light and heavy fascines onto foundation along coasts of riverbed. In the beginning light fascines are laid in solid rows in foundation along slope line, and metal wires are tightened above to form coarse net. Heavy fascines are arranged in tight rows above net and light fascines normally to their rows along line of slope inclination. The second coarse metal net is tightened above layer of heavy fascines and is fixed to metal wires in foundation. Light and heavy fascines are prepared in advance. Light fascines are made of dry ripe cane with diametre of 0.15 - 0.2 m and length of 1.7 - 2.5 m. Heavy fascines are made with diametre of 0.3-0.7 m and length of 2-2.5 m from soil filler and flexible shell. Filler is made of bags filled with fertile soil and added seeds of permanent grasses and bushes with developed root system. Shell of heavy fascines are made of tight layers of dry cane and flexible gabion net tightened around cane layers. Coarse nets in foundation and on top are bound to each other and fixed to anchors, which are arranged in slope above support and at the distance from each other. ^ EFFECT: increased efficiency of structure operation, its biopositive effect and prolonged service life. ^ 2 cl, 4 dwg
