Description

Flood control dike suitable for salt lake area Technical Field The utility model relates to the field of water conservancy flood control, in particular to a flood control dike suitable for a salt lake region. Background In recent years, the surface of a land salt lake in China is affected by various factors (such as increase of glacier water melting and soil degradation) to show an expansion trend. The expansion of the lake surface of the salt lake easily causes the flood disasters of the salt lake, and the salt pan and the production equipment facilities of salt lake enterprises can be destroyed, so that larger economic loss is brought. For this reason, it is necessary to construct a flood dike in a salt lake region. The existing flood control dike is mainly built by clay, but the clay material is relatively short and needs to be transported, the building cost is high, and if the excavated saline soil is used as a dike building material, the flood control dike can be subjected to water dissolution, dike base leakage, instability and damage and the like. Therefore, improvement of the anti-seepage performance of the saline soil flood dike is urgent. Disclosure of Invention In view of the above, the utility model provides a flood control dike suitable for salt lake areas, which utilizes an impermeable layer and an impermeable wall to perform impermeable treatment, thereby solving the problem that the saline soil flood control dike is dissolved in water and leaks out of a foundation. In order to achieve the above purpose, the utility model adopts the following technical scheme: The utility model relates to a flood control dike suitable for a salt lake region, which comprises a flood control dike main body filled with saline soil, a clay layer, an impermeable layer and an impermeable wall, wherein the impermeable layer is provided with an inclined impermeable part paved on the water surface of the flood control dike main body and a horizontal impermeable part extending from the bottom of the water surface of the flood control dike main body; The clay layer is paved on the impermeable layer, the banquette height of the clay layer is lower than the top elevation of the main body, the free end part of the inclined impermeable part extends out of banquette of the clay layer and is buried in the flood control dike main body, the free end part of the inclined impermeable part is of a U-shaped structure with an upper opening, the impermeable wall is inserted into the soil body at the bottom of the impermeable layer, which is close to the water surface, and the free end part of the horizontal impermeable part extends out of the bottom of the clay layer and is coated on the upper part of the impermeable wall. The anti-seepage dam has the beneficial effects that the upper part of the anti-seepage layer is buried in the main body of the anti-seepage dam, and the lower part of the anti-seepage layer extends to the anti-seepage wall and is connected with the anti-seepage wall, so that the anti-seepage layer and the anti-seepage wall are connected to form an integral anti-seepage system, and water flow can be prevented from immersing into the main body of the anti-seepage dam, thereby solving the problem that the saline soil anti-seepage dam is dissolved in water and the foundation is leaked. In addition, the utility model has good seepage-proofing performance, can realize large-scale application of the saline soil, solves the technical problems of shortage of construction materials and high transportation cost of the flood control dike in the salt lake area, and further reduces engineering investment.
