Problems solved by technology

[0007] The windproof and sand-fixing greening planting method disclosed in this patent document can play a certain windproof effect by setting up multiple belt-shaped sand barriers in the mobile sand dune zone, but the windproof ability of the belt-shaped sand barriers is limited, and it is easy to be eroded by strong winds. Fundamentally, sand fixation cannot effectively prevent sandy desertification

Abstract

The invention discloses a preparation method of a curing agent applicable to sandy soil, and belongs to the technical field of environmental protection engineering. The preparation method is characterized by comprising the following steps that 1, sodium carboxy methylcellulose and water are subjected to stirring and dissolving according to the mass ratio of 1:20, and a sodium carboxy methylcellulose solution is obtained; 2, anionic polyacrylamide and water are subjected to stirring and dissolving according to the mass ratio of 1:100, and an anionic polyacrylamide solution is obtained; 3, ferrous chloride and water are subjected to stirring and dissolving according to the mass ratio of 1:50, and a ferrous chloride solution is obtained; 4, under the room temperature condition, the sodium carboxy methylcellulose solution, the anionic polyacrylamide solution and the ferrous chloride solution are sequentially added into water for mixing and prepared into the curing agent. The curing agent has the advantage of being high in adsorption and cementation, inner pores of soil particles can be filled with the curing agent mixed with the sandy soil, the mixture serves as natural cement of the soil, the cured sand particles are not prone to disperse, and the sand fixation and anti-wind capability are high.

Description

technical field [0001] The invention relates to the technical field of environmental protection engineering, in particular to a method for preparing a curing agent suitable for sandy soil. Background technique [0002] Land desertification is an ecological environment problem caused by land degradation caused by human activities. China is one of the countries most seriously affected by desertification. In 1999, the area of ​​desertified land in my country reached 267.4 square kilometers, accounting for 27.9% of the total land area of ​​the country. %, and is still expanding at a rate of 3140 square kilometers every year. Among them, the area of ​​wind-eroded desertification is 187.3 square kilometers, accounting for 70% of the total desertified land area, manifested as desertification of farmland and grassland, mainly located in the arid and semi-arid areas of Northwest China, such as Inner Mongolia, Xinjiang, Gansu, Ningxia, and northern Shaanxi. In the arid and semi-arid r...
