Sandy soil geological retaining dam solidified by using construction waste
The invention discloses a sandy soil geological retaining dam solidified by using construction waste. The sandy soil geological retaining dam solidified by using the construction waste comprises a dambody formed by tamping sandy soil and a cement concrete layer poured on the surface of the dam body, a water seepage prevention structure is arranged between the upstream face of the cement concretelayer and the dam body, the water seepage prevention structure comprises a first hydration isolation layer close to the upstream face and a second hydration isolation layer close to the dam body, anda reinforcing filling layer is formed between the first hydration isolation layer and the second hydration isolation layer. According to the sandy soil geological retaining dam solidified by using theconstruction waste, hydration isolation layers take the construction waste as aggregate, and quick lime and cement are mixed, so that a filling layer with high porosity relative to the middle reinforcing filling layer is formed, fault isolation with different porosities is formed at the junction of the reinforcing filling layer and the hydration isolation layers, and the permeation rate and the permeation amount of water in the water seepage prevention structure are greatly reduced; and quick lime and cement are selected and can be combined with seeped water to be coagulated and solidified, awaterproof interlayer with certain strength and density is formed, permeation of the water is prevented, and the construction waste is reused.
一种利用建筑垃圾固化的砂土地质拦水坝，包括由砂土夯筑而成的坝体和浇筑在其表面的水泥混凝土层，在水泥混凝土层的迎水面和坝体之间具有防渗水结构，防渗水结构包括与迎水面紧挨的第一水化隔离层和与坝体紧挨的第二水化隔离层，在第一水化隔离层和第二水化隔离层之间形成增强填充层。本发明的水化隔离层均是以建筑垃圾为骨料，混杂生石灰、水泥，从而形成相对中间的增强填充层较高孔隙率的填筑层，进而在增强填充层和水化隔离层交界处形成孔隙率不同的断层隔离，大幅度降低水在其内的渗透速率和渗透量；选用生石灰和水泥，能够与渗水结合凝结固化，形成具有一定强度和致密度的防水隔层，防止了水的渗透，而且使建筑垃圾得到再利用。
