Method for rapidly building anti-seepage salt pond

Abstract

The invention relates to a method for rapidly building an anti-seepage salt pond, which comprises the steps of constructing a pond dam, carrying out leveling and film laying on the bottom of the pond, injecting water and filling loess slurry, and finishing a loess slurry pool plate, and the like. In the method disclosed by the invention, the step of constructing a pond dam can be implemented by using underground loess locally produced in Laizhou Bay, but in traditional processes, clay must be used in the construction of pond dams, the application of clay has more and more obvious shortcomings, one shortcoming is shown in the aspects of trouble transportation and high cost, and another shortcoming is that the clay can be subjected to water seepage, thereby causing the waste of brine; due to the application of a polyethylene plastic film, in the process of salt manufacturing, brine is separated from the bottom of the pond through the plastic film, so that a water seepage phenomenon can be prevented; and through adopting the way, in the process of salt manufacturing, the application amount of brine is reduced by 50%. The method is simple in operation, and compared with traditional processes, the cost is reduced by 20%, and the beach building time is reduced by about 75%.

Description

technical field [0001] The invention relates to a method of constructing a salt pan. Background technique [0002] There are vast salt fields along the coast of China, and the salt field method is still the most important one in the current salt production technology. In the old-fashioned method of building salt pans, the material used for the beach fields mainly relies on clay, and clay is used to protect the dam and lay the bottom of the salt pan. Pull the clay at the bottom into the pond and soak it in brine of 10-12°Bé, soak the mud in the clay thoroughly and remove the brine, then turn the clay up and down to mix the clay into a thin mud and spread it evenly At the bottom of the pool, when the load capacity of the mud can bear people, press the mud in a "ten" style with a small rock ark. After pressing the "ten" twice, soak it in brine at 13-14°Bé, and remove the water after soaking. Press twice with a medium-sized pot in a "ten" shape, then soak in brine at 17-18°Bé,...

AI Technical Summary

Problems solved by technology

[0003] In the entire old method of building salt pans, one is that there is no anti-seepage treatment; the other is that there is a large demand for clay, and the clay must be clay with high ion content and must contain a certain amount of sand to achieve its quantity optimization. Only when the particle size is equipped can the strength, hardness, and pressure meet the standards for salt collection and fishing; the third is that the personnel load is increased; the fourth is that it takes a long time to build a beach; During the salt drying or brine making operation, the pool plate will be seriously damaged, resulting in the increase of insoluble matter in the original salt, and the hardness of the upper and lower layers of the pool bottom is different, which will also accelerate the leakage of the pool plate and waste precious brine resources

Therefore, the raw salt produced by the old beach building process looks black, has high insoluble impurities, and is not easy to collect by mechanical operations.
