Problems solved by technology

This material has poor permeability and water resistance, and some organic polymer materials are toxic, which limits its use
Using water glass slurry to fix sand is easy to gel and solidify, and the curing reaction is incomplete, easy to be damaged by external force and cause the second alkali pollution. In addition, plants cannot grow in an alkaline environment with a large amount of water glass.
Cement slurry sand fixation only utilizes the cement slurry sprayed on the sand surface to condense and solidify and then cover it. However, the climate in desert areas is hot and dry, and the temperature of the sand surface is high. Can form a low-strength and thin solidified layer, easy to crack, unable to retain water and fix sand for a long time

experiment approach 1

[0019] Configure a certain mass percentage of 19% gypsum powder, 8% bentonite, 60% sheep manure, 12% sawdust powder, and 1% urea. Stir the above ingredients evenly by mechanical stirring, and select appropriate grass species to mix with the above materials. Spread evenly on the sand surface to form a 1-2 cm thick layer, and finally sprinkle water to penetrate the sand-fixing composite layer.

experiment approach 2

[0021] Configure a certain mass percentage of 25% gypsum powder, 10% bentonite, 50% sheep manure, 10% sawdust powder, and 5% urea. Mix the above ingredients evenly by mechanical stirring, and select appropriate grass species to mix with the above materials. Spread evenly on the sand surface to form a 1-2 cm thick layer, and finally sprinkle water to penetrate the sand-fixing composite layer.

experiment approach 3

[0023] Configure a certain mass percentage of 30% gypsum powder, 8% bentonite, 45% sheep manure, 15% sawdust powder, and 2% urea. Mix the above ingredients evenly by mechanical stirring, and select appropriate grass species to mix with the above materials. Spread evenly on the sand surface to form a 1-2 cm thick layer, and finally sprinkle water to penetrate the sand-fixing composite layer.

Abstract

The invention relates to a method to sand solidification and planting method by using semi-hydrated gypsum and anhydrous gypsum compouonding material. It includes the following steps: mixing coagulant from 10-40wt% semi-hydrated gypsum or anhydrous gypsum, 8-20wt% bentonite, 30-60wt% ordure of herbivore, 10-20wt% saw dust powder, and 1-5wt% urea; whisking to equal; paving the material onto the surface of sand for 1-2cm thickness and solidifying. The invention could obviously improve the survival rate of sand plant and is benefit to improve the efficiency of sand solidification and planting.

Description

technical field [0001] The invention relates to a method for fixing sand and planting with hemihydrate gypsum and anhydrous gypsum composite materials. Background technique [0002] The traditional and existing sand fixation methods mainly use the wheat straw grid method, which cannot solve the problem in essence. The petroleum asphalt sand control technology uses crude oil residue, asphalt and emulsified asphalt to spray on the surface of the desert sand to form a continuous consolidation layer. . Decomposition of petroleum may pollute the environment. Polymer synthetic chemical materials can use cohesive or viscous polymer materials to form huge networks or active groups by using their huge molecular chains to bond dispersed non-cohesive sand together. Form a certain rigid or elastic stability that is not easy to be crushed, so as to achieve the purpose of stable sand fixation. This material has poor permeability and water resistance, and some organic polymer materials ...
