Novel three-proofing salt field and construction method thereof

Abstract

The invention discloses a novel three-proofing salt field and a construction method of the three-proofing salt field. The salt field is formed by the enclosing of a soil layer bottom plate and an earth dam. The novel three-proofing salt field is characterized in that anti-seepage cloths are paved inside and on the top of the soil field bottom plate and the earth dam; the anti-seepage cloths are closely welded; a rain-proof film is arranged on the top part of the salt field, and the rain-proof film is dragged by a steel wire rope; and a layer of KCl crystalline is covered on the anti-seepage cloth on the bottom part of the salt field as a strength layer. The invention further relates to a construction method for the novel three-proofing salt field. The salt field provided by the invention is not affected by device grinding, soil and weather, not only can be used in an arid region with less rainfall, but also can be used for evaporating a crystallization residue solution by a salt field technology in a region with more rainfall. According to the anti-seepage technology provided by the invention, the mother liquor can be prevented from leaking, and the environment protection is facilitated. According to an effective anti-pressure technology, a large device can be used for achieving a mechanical operation, so that the working efficiency is greatly improved, and the effects of preventing seepage, pressure and rainfall can be realized.

Description

technical field [0001] The invention relates to a salt field, in particular to a novel three-proof salt field which is leak-proof, pressure-proof and rain-proof; the invention also relates to a construction method of the new three-proof salt field. Background technique [0002] In the prior art, there are mainly two ways to process the mother liquor of salt mine processing. One is to use natural evaporation and crystallization in salt fields. This method is suitable for areas with very little rainfall and dry climate, and is often used in salt lakes such as Qinghai and Xinjiang in western my country. The second method is to use an evaporator to heat and evaporate strongly. This method is not affected by the climate and can be used in places with abundant rainfall. However, this method requires artificial heating to consume a large amount of energy, increases production costs, and reduces enterprise benefits.
