Embodiment 1

[0026] A kind of method for fixing sand based on magnesium phosphate cement as binder, is characterized in that, comprises the following steps:

[0027] S1, the NH 4 h 2 PO 4 : boric acid: magnesium oxide: fine sand is prepared in a ratio of 1:0.5:15:30 by weight and fully mixed;

[0028] S2. Stir the mixed material obtained in step s1 with water in a ratio of 3:1 by weight to obtain a magnesium phosphate cement semi-wet material;

[0029] S3. Pile the semi-moist material of magnesium phosphate cement obtained in S2 on the sand dunes to form sand ridges to play the role of sand prevention and sand fixation.

[0030] The sand ridge is as image 3 and 4 As shown, the setting of the sand ridge is as follows figure 2 shown.

Embodiment 2

[0032] A kind of method for fixing sand based on magnesium phosphate cement as binder, is characterized in that, comprises the following steps:

[0033] S1, the NH 4 h 2 PO 4 : boric acid: magnesium oxide: fine sand is prepared in a ratio of 1:0.1:1:10 by weight and fully mixed;

[0034] S2. Stir the mixed material obtained in step s1 and water evenly in a ratio of 2:1 by weight to obtain a semi-wet material of magnesium phosphate cement;

[0035] S3. Pile the semi-moist material of magnesium phosphate cement obtained in S2 on the sand dunes to form sand ridges to play the role of sand prevention and sand fixation.

[0036] The sand ridge is as image 3 and 4 As shown, the setting of the sand ridge is as follows figure 2 shown.

Embodiment 3

Abstract

The invention discloses a sand stabilizing method based on magnesium phosphate cement as a binder. The method comprises the following steps: adequately mixing soluble phosphate, a delayed coagulation material, magnesium oxide and filler according to the weight proportion of 1:(0.1-1):(1-30):(10-100); uniformly stirring a mixture obtained in the step S1 and water according to the weight proportion of (1-10):1, to obtain a magnesium phosphate cement half-wet material; and stacking the magnesium phosphate cement half-wet material obtained in the step S2 to form a sand barrier for preventing and stabilizing the sand. The method has the characteristics of cheap cost, environmental protection, stable performance, strong weather-proof ability, and simple and convenient construction, and has the extensive application prospect on the desertification control engineering.

Description

technical field [0001] The invention belongs to the technical field of desertification control, and in particular relates to a sand fixing method based on magnesium phosphate cement as a binder. Background technique [0002] my country is one of the countries with serious desertification hazards in the world. As an important national policy, desertification control has been highly valued. The key to desertification control is sand prevention and sand fixation. After several generations of unremitting efforts, our country has explored the method of combining plant sand fixation and mechanical sand fixation, which has alleviated the invasion of quicksand and the process of desertification to a certain extent. Among them, mechanical sand fixation generally uses materials such as wheat straw, stones or clay to make 1m×1m (dimensions vary) squares, forming a basic protection system against quicksand hazards. Then plant psammophytes (such as Artemisia oleifera, Artemisia annua, ...
