Problems solved by technology

[0002] Irrigation facilities are indispensable for irrigation and drainage when improving saline-alkali soil. In building irrigation facilities, the foundation of the building area needs to be treated first, such as using special mixed soil for foundation hardening treatment to support the facilities. , and the mixed soil will use various materials such as cement, sandstone and filling soil, etc., but due to the saline-alkali characteristics of saline-alkali soil, the above-mentioned building materials are vulnerable to erosion and weakened very seriously, which cannot meet the requirements for facilities. Supporting effect, over time, the irrigation facilities will sink, causing cracks or fractures in the irrigation facilities

Abstract

The invention discloses irrigation facility composite soil prepared by using saline alkali soil. A raw material saline-alkali soil, coal ash, and slag cements are fully mixed in proportion, and waterand an additive are added with stirring in order to prepare the product. The weight ratio of the saline-alkali soil to the coal ash to the slag cements is 3-5:0.2-0.5:0.8-1.2, and the amount of wateris as follows: one cubic meter of a mixture of the saline-alkali soil, the coal ash and the slag cements employs 200-500 kg water. The additive is an emulsion shaped calcium stearate fluid suspension,wherein based on the slag cements, the weight of calcium stearate is 0.1-1.5%. The product is adapted to saline-alkaline characteristics of the saline-alkaline soil, and performance is not easy to weaken by corrosion, and supporting and holding effects for the facility are guaranteed.
