Protection treatment method for expansive soil channel slope
The invention provides a protection treatment method for an expansive soil channel slope, which adopts slope surface closing and slope top seepage prevention according to expansive soil engineering characteristics, underground water seepage characteristics, an expansive soil channel slope damage type and an expansive soil slope deformation damage mechanism, and adopts a seepage prevention and slide-resistant pile supporting scheme for structural surface control type landslide. And with the assistance of slope drainage and slope riding track seepage prevention measures, external water is effectively prevented from entering the slope body, and the expansive soil canal slope is kept stable. The lining plate is directly arranged on the cement modified soil replacing and filling layer, a traditional geomembrane, gravel cushion and check valve combined structure is omitted, the anti-seepage function is achieved through cement modified soil, the defects that a saturated zone is formed in the gravel cushion during engineering operation, and uplift pressure is formed when canal water disappears due to water blocking of the geomembrane are overcome, and the construction efficiency is improved. The stability of the expansive soil channel side slope structure is greatly improved, and potential safety hazards of the expansive soil channel side slope are greatly reduced.
本发明提供一种膨胀土渠道边坡的保护处理方法，依据膨胀土工程特性、地下水渗流特性、膨胀土渠坡破坏型式及膨胀土边坡变形破坏机理，采取坡面封闭、坡顶防渗，针对结构面控制型滑坡采取防渗、抗滑桩支挡方案，辅以坡面排水、坡面马道防渗措施，有效控制外部水体进入坡体，维持膨胀土渠坡稳定。本发明将衬砌板直接置于水泥改性土换填层上，取消传统的“土工膜+砂砾垫层+逆止阀”组合结构，由水泥改性土实现防渗功能，规避了砂砾垫层在工程运行时形成饱水带、土工膜在渠水消退时阻水形成扬压力的弊端，大大提升了膨胀土渠道边坡结构的稳定性，大大降低了膨胀土渠道边坡的安全隐患。
