Ecological protection method for expansive soil slope
The invention provides an ecological protection method for an expansive soil slope. A plurality of modified anchoring columns and a plurality of plant planting anchoring units are distributed on the slope surface of the expansive soil slope, plants with developed root systems are planted in the plant planting anchoring units, each modified anchoring column comprises an anchoring pipe, wherein permeation holes with the diameter of 2mm are densely distributed in the surface of the anchoring pipe, and the anchoring pipe is filled with collapsible loess and a construction waste inverted filter layer from bottom to top. According to the ecological protection method, holes are drilled and conical holes are dug in the slope surface of expansive soil, then the drilled holes are filled with the collapsible loess and construction waste, and therefore the modified anchoring columns for improving the surrounding expansive soil are formed; meanwhile, an anchoring structure is arranged in each conical hole, the anchoring structures can anchor and improve soil near the conical holes to form anchoring joints, and therefore shallow landslide is prevented; and the plants with the developed root systems are planted in the anchoring structures, the root systems of the plants are used for preventing water and soil loss, and therefore the effect of protecting the ecological environment and system ofthe expansive soil slope is achieved.
一种膨胀土斜坡生态保护方法，在膨胀土斜坡的坡面上分布有若干改性锚固柱和若干植物种植锚固单元，植物种植锚固单元内种植有根系发达植物，改性锚固柱包括表面密布有直径为2mm渗透孔的锚固管，在锚固管内自下而上填充有湿陷性黄土和建筑垃圾反滤层。本发明通过在膨胀土坡面上钻孔和挖设锥形孔，之后在钻孔内填充湿陷性黄土和建筑垃圾，从而形成对周边膨胀土改良的改性锚固柱，同时在每个锥形孔内设置锚固结构，锚固结构能够将锥形孔附近的土体进行锚固和改良，形成锚固节点，防止出现浅层滑坡，在锚固结构内种植根系发达的植物，利用其根系来防止水土流失，从而起到了保护膨胀土坡生态环境和体系的作用。
