Abstract

The invention belongs to the technical field of soil improvement, particularly relates to an improvement system for severely salinized soil, and provides the following scheme aiming at the technical problems of long prevention and treatment period, low soil improvement efficiency and salt waste caused by incapability of effectively collecting and utilizing salt in soil in an existing vertical shaft drainage mode. The system comprises a solid pipe vertical shaft and a floral pipe vertical shaft, an inner circulation mechanism is arranged at the floral pipe vertical shaft, an outer circulation mechanism is arranged at an upper port of the solid pipe vertical shaft, the outer circulation mechanism comprises a filtering tank, a mixing tank and an evaporating tank which are sequentially connected, and the inner circulation mechanism comprises a water pump. Water in a saline water layer can be pumped into the outer circulation mechanism by the water pump to react, finally generated steam is guided into the floral tube vertical shaft to dilute the saline water layer at the position, and in addition, high-temperature steam heats the water in the saline water layer to accelerate diffusion of saline water in surrounding soil, so that salt in the soil is rapidly separated out, and the soil improvement efficiency is improved.

Description

Technical field[0001]The present invention relates to soil improvement techniques, and more particularly to a modified system for severe saline soil.Background technique[0002]Soil salinization means that the salt of the soil underdee or groundwater is rising from the hair pipe to the surface, and after evaporation of water, the salt accumulates in the surface soil. It means the phenomenon or process of easy-to-soluble salts in the soil surface accumulation, also known as the salt basis. China's saline soil or a wide range of saline is widely distributed, large, and has more type, with a total area of ​​about 100 million hm2. It mainly occurs in drought, semi-arid and semi-moist. The soluble salts of saline soil mainly include sulfates, chlorides, carbonates, and heavy carbonates such as sodium, potassium, calcium, magnesium. Sulfates and chlorides are generally neutral salts, carbonates, and heavy carbonates for basic salts.[0003]Shaft drains, is a well-formed well, pumping groundwa...
