Expansive soil slope ecological protection structure and method
The invention discloses an expansive soil side slope ecological prevention and control structure and method. The expansive soil side slope ecological prevention and control structure comprises a plain expansive soil layer, an ecological protection layer and a water-resisting layer. The ecological protection layer comprises a biological matrix improvement layer, lateral root type plants and main straight root type plants, and the water-resisting layer comprises an MICP technology solidification layer and gravel holes; the biological matrix improvement layer, the MICP technology solidification layer and the element expansive soil layer are sequentially intersected in a step shape from the surface to the inside, the lateral root type plants and the main straight root type plants are alternately planted in a delta shape, and the gravel holes are connected with the biological matrix improvement layer and the element expansive soil layer. The invention further provides an expansive soil slope ecological prevention and control method. The method can effectively prevent seepage and preserve moisture, improve the reinforcement anchoring capability of vegetation roots, inhibit the surface cracking and strength attenuation of the expansive soil side slope after alternation of sunny and rainy days, guarantee the long-term stability of the expansive soil side slope, provide a reasonable way for treating agricultural wastes, and have important significance on ecological environment protection.
一种膨胀土边坡生态防治结构及方法，所述膨胀土边坡生态防治结构包括素膨胀土层、生态防护层和隔水层；所述生态防护层包括生物基质改良层、侧向根型植物以及主直根型植物，所述隔水层包括MICP技术固化层和砂石孔洞；所述生物基质改良层、MICP技术固化层和素膨胀土层由表往里以阶梯状依次相交，侧向根型植物和主直根型植物以品字形交替种植，砂石孔洞连接生物基质改良层和素膨胀土层。本发明还包括一种膨胀土边坡生态防治方法。本发明能够有效防渗保湿，提高植被根系加筋锚固能力，抑制晴雨交替后膨胀土边坡表层开裂及其强度衰减，保障膨胀土边坡的长期稳定性，同时提供一种处理农业废弃物的合理途径，对生态环境保护具有重要意义。
