Guide suction type expansive soil slope shallow water control covering system based on capillary retardation mechanism
The invention discloses a guide suction type expansive soil slope shallow water control covering system based on a capillary retardation mechanism. The system sequentially comprises a vegetation layer, a fine-grained layer, a guide suction layer, a coarse-grained layer and a water retention fine-grained layer from top to bottom, and a drainage ditch is arranged at the slope toe of a slope, whereinthe guide suction layer comprises a central retarding layer and a silt belt, and geotechnical cloth layers are laid on the contact faces between the silt belt and the central retarding layer, the contact faces between the silt belt and the coarse-grained layer and the contact faces between the central retarding layer and the fine-grained layer respectively. On the basis of the capillary retardation principle, infiltration rainfall is dredged in a retardation, guide drainage and absorption mode during rainfall, the water content of an expansive soil slope can be effectively kept stable, the influence of rainfall infiltration on the slope stability is reduced, the overall stability of the slope is enhanced, the influence of dry-wet circulation on the expansive soil slope can be reduced, andthe characteristics of convenient material taking, good durability, low manufacturing cost and the like are achieved.
本发明公开了一种基于毛细阻滞机理的导吸式膨胀土边坡浅层控水覆盖系统，该系统由上至下依次为植被层、细粒层、导吸层、粗粒层和保水细粒层，边坡的坡脚处设有排水沟。其中导吸层包括中心阻滞层和粉土带。所述粉土带与中心阻滞层、粉土带与粗粒层、中心阻滞层与细粒层的接触面上分别铺设了一层土工布。本发明基于毛细阻滞原理，在降水时采用阻滞、导排、吸收的方式对入渗的降水进行疏导，能够有效保持膨胀土边坡的含水量稳定，减小降水入渗对边坡稳定性的影响，增强边坡整体稳定性并能减小干湿循环对膨胀土边坡的影响，且具有取材方便、耐久性好、造价低等特点。
