Geogrid reverse wrapping modified expansive soil flexible ecological slope protection structure and construction method
The invention provides a flexible ecological slope protection structure with geogrids reversely wrapped with modified expansive soil and a construction method. The flexible ecological slope protection structure comprises a foundation, a waterproof layer, an inverted filter layer and a flexible protection face composed of the geogrids and the modified expansive soil. The waterproof layer is tightly attached to the slope surface and is provided with the inverted filter layer; modified expansive soil is arranged on the inverted filter layer, is reversely wrapped by geogrids and is stacked in layers in a stepped manner to form a flexible protective surface; the inverted filter covers a foundation on the riding track platform part, the platform part is provided with a water filtering ditch, a water filtering pipe is arranged in the water filtering ditch, and the inverted filter extends and fills the water filtering ditch; and the drip irrigation pipes are horizontally arranged between two adjacent layers of geogrids. According to the method, the excavated expansive soil is reasonably utilized and modified, the expansive soil and the geogrid form the flexible protection face, the expansive soil slope can be effectively treated, and the purposes of being stable in structure, economical, reasonable and capable of restoring a slope vegetation ecological system are achieved.
本发明提供了一种土工格栅反包改性膨胀土柔性生态护坡结构与施工方法，它包括基础，防水层，反滤层，土工格栅与改性膨胀土构成的柔性护面。防水层紧贴坡面，其上为反滤层；反滤层上有改性膨胀土，改性膨胀土由土工格栅反包，呈台阶式成层码放，构成柔性护面；反滤层在马道平台部分覆盖有基础，平台部分有滤水沟，滤水沟中有滤水管，反滤层延伸并充填滤水沟；滴灌管水平布置在相邻两层土工格栅之间。本发明合理利用开挖后的膨胀土，对其进行改性，与土工格栅一起构成柔性护面，能够有效治理膨胀土边坡，达到结构稳定，经济合理，恢复坡面植被生态系统的目的。
