Description
Technical field
The utility model relates to a kind of intermediate anchoring structure of long slope seepage control layer, and this structure is particularly useful for the long side slope of super large liquid storage tank.
Background technology
The volume of super large liquid storage tank reaches millions of cubic meter, generally deposit the strong brine of recirculated water, demineralized water and the various medicament added in industrial processes and generation, its composition is main based on organic matter and inorganic salts, and these pollutants have larger pollution risk to underground water.Liquid storage tank pond body is laid the impervious materials such as HDPE geomembrane can block strong brine and permeate downwards, but due to impervious material self and strong brine additional Action of Gravity Field for a long time, only establish on top, slope single-stage anchoring to be not enough to resist the stretching of impervious material in side slope and slippage, thus affect the anti-seepage effect of whole liquid storage tank.
In order to prevent the generation of above-mentioned situation, conventional design is the gradient to 1 reducing side slope: 3, increases the frictional force of impervious material and side slope basal plane, thus prevent the displacement of impervious barrier by slowing down side slope, but the method increase civil engineering and seepage control project amount, be unfavorable for cost-saving.According to the liquid storage tank gradient, length of grade and execution conditions, adopt the design of setting up intermediate anchor platform and increasing long grade of side slope, both the stability of impervious material in the long side slope of liquid storage tank and the reliabilities of antiseepage function such as HDPE geomembrane can be strengthened, the volume of liquid storage tank can be increased again, reduce construction costs.
Summary of the invention
The utility model has set forth a kind of intermediate anchoring structure for the long slope seepage control layer of super large liquid storage tank, and this structure, on the basis of single-stage anchoring, sets up one-level anchored platform in long side slope centre position, increases the gradient of the upper and lower side slope of intermediate anchor platform simultaneously.
