Anti-corrosion steel wire gabion ecological invisible revetment and construction method thereof
The invention provides an anti-corrosion steel wire gabion ecological invisible revetment and a construction method thereof. According to the revetment, a gravel inverted filter layer, inverted filter geotechnical cloth, an anti-corrosion steel wire gabion filled with stone, a cultivated soil layer and a vegetation layer are arranged on the surface of foundation soil of a bank slope from bottom to top, a protection foot is arranged at the bottom of the bank slope, and a protection apron is arranged on a near-bank riverbed on the outer side of the protection foot; the softening coefficient of the stone is not smaller than 0.7, the saturated compressive strength is not smaller than 50MPa, the block density is not smaller than 2400kg/m< 3 >, the maximum water absorption rate is not larger than 10%, the median particle size ranges from 1.5D to 2.0D, and D is the size of gabion meshes; the particle size of 85% or above of the stone is larger than 1.0D; and the porosity of the filled anti-corrosion steel wire gabion is not larger than 35%. According to the anti-corrosion steel wire gabion ecological invisible revetment and the construction method thereof, the anti-corrosion steel wire gabion is used as a framework, the anti-corrosion steel wire gabion is filled with the proper stone, the stability of the revetment is improved, the anti-scouring and anti-abrasion performance is enhanced, the stability of the bank slope under the flood condition can be guaranteed, and flood prevention and impact resistance are achieved; and meanwhile, the ecological environment of the revetment is improved.
本发明提供一种防腐蚀钢丝石笼生态隐形护坡及其施工方法，所述护坡在岸坡的基土表面由下而上设置有碎石反滤层、反滤土工布、填充有石料的防腐蚀钢丝石笼、耕作土层和植被层，在岸坡底部设置有护脚，护脚外侧近岸河床上设置有护坦；所述石料的软化系数不小于0.7，饱和抗压强度不小于50MPa，块体密度不小于2400kg/m3，最大吸水率不大于10％，中值粒径介于1.5D～2.0D之间，其中D为石笼网孔尺寸；85％以上石料的粒径应大于1.0D；填充后的防腐蚀钢丝石笼的空隙率不大于35％。本发明通过以防腐蚀钢丝石笼为骨架，并在防腐蚀钢丝石笼内填充合适的石料，提高了护坡的稳固性，增强抗冲刷、抗磨损性能，能够保证洪水条件下岸坡稳固，防洪抗冲；同时改善了护坡生态环境。
