Wide graded soil impermeable soil material
The embodiment of the invention provides a wide graded soil impermeable soil material. The wide graded soil impermeable soil material has good compactibility and comprises the following grain groups of medium gravels with the grain diameter of 10 mm to 5 mm, fine gravels with the grain diameter of 5 mm to 2 mm, sand with the grain diameter of 2 mm to 0.075 mm and fine grains with the grain diameter less than 0.075 mm; and the value range of the mass percentage of each grain group is as follows, 25%-40% of the medium gravels, 14%-20% of the fine gravels, 25%-30% of the sands and 10%-37% of thefine grains. The wide graded soil impermeable soil material has the advantages of low cost, high filling density, high shear strength, small subsidence deformation, difficulty in shrinkage cracking, excellent impermeable performance, no piping risk and the like, and has obvious advantages compared with traditional impermeable materials such as clay and geotextile; and meanwhile, the requirements of good compactness and common impermeability standards can also be met.
本发明实施例提供了一种宽级配土防渗土料，具有良好压实性，包括以下粒组：中砾：颗粒直径10mm～5mm，细砾：颗粒直径5mm～2mm，砂：颗粒直径2mm～0.075mm，细粒：颗粒直径<0.075mm；各粒组质量百分比取值范围分为：中砾：25％～40％，细砾：14％～20％，砂：25％～30％，细粒：10％～37％。本发明实施例提供了一种宽级配土防渗土料具有成本低廉、填筑密度大、抗剪强度高、沉陷变形小、不易收缩开裂、防渗性能优异，没有管涌的风险等优点，相比粘土、土工布等传统防渗材料具有明显的优势，同时，还可以满足良好的压实性和普通防渗标准的要求。
