Embodiment 1

[0069] Example 1 (integrated sand-fixing board)

[0070] Such as figure 1 As shown, the integrated sand-fixing board includes a sand-fixing board body 1 and a plurality of magnesium bars 2 fixed on the sand-fixing board body 1, wherein the sand-fixing board body 1 is solidified by magnesium cement mortar, and the magnesium One end of the magnesia tendon 2 is solidified inside the sand-fixing board, and the other end is located outside the body of the sand-fixing board to form a fixed end. pulp.

[0071] The magnesium cement mortar can adopt one of the following examples 2.1-2.3 or any composition in any proportion, and the magnesium cement paste can use one of the following examples 2.1-2.3 or any composition in any proportion.

Embodiment 2

[0074] Embodiment 2 (preparation of magnesium cement clean slurry and magnesium cement mortar)

[0075] The water in the following embodiments is not limited, it can be tap water or river and lake water.

[0076] 2.1 Preparation of magnesium oxychloride cement paste and magnesium oxychloride cement mortar

[0077] Described magnesium oxychloride cement mortar is prepared by following method:

[0078] Step 1, dissolving magnesium chloride in water to obtain a magnesium salt solution with a concentration between 20-30Be °;

[0079] Step 2, active magnesia, sandy soil (sandy soil is sand and / or soil, obtained from sand control locality) and described magnesium salt solution by mass ratio 1:(5-15):(0.5-1.5) (optimum ratio 1:8:0.9, in addition, 1:5:1.5, 1:15:0.5, 1:5:0.5) can also be used to mix and stir evenly to obtain magnesium oxychloride cement mortar.

[0080] The magnesium oxychloride cement clean slurry is prepared by the following method:

[0081] Step 1, dissolving ma...

Embodiment 3

[0107] 3.1 Prepare the mold:

[0108] Made of stainless steel plate as figure 2 The rectangular sand-fixing plate mold shown in the figure includes a bottom plate and four side wall plates. The four corners of the side wall plates are connected by snap buttons, and a number of holes are opened on one of the side wall plates. Hole is provided with six in the present embodiment, and the internal dimension of mold is long (A) * wide (B) * thick (C)=(100cm-200cm) * (20cm-50cm) * (1.5cm-5cm), the hole The diameter is 1cm-2cm.

[0109] 3.2 Preparation of integrated sand-fixing board:

[0110] Step A. prepare magnesium cement clean slurry and magnesium cement mortar 6 according to the method of embodiment 2.1, 2.2 or 2.3:

[0111] Step B. Prepare magnesium bars:

[0112] Bind plant fibers (such as bamboo tendons, straw, reed stalks, etc. or other plant straw materials) into tendons with a diameter smaller than holes, the length of the tendons is 10-30cm, soak the tendons in the ...

Abstract

The invention discloses an integrated sand stabilization plate and a preparation method and sand stabilization method thereof. The integrated sand stabilization plate comprises a sand stabilization plate body and a plurality of magnesium reinforcing ribs fixed to the sand stabilization plate body, the sand stabilization plate body is formed by curing magnesium cement mortar, and one end of each magnesium reinforcing rib is cured in the sand stabilization plate. The other end of the magnesium reinforcing rib is located outside the sand stabilization plate body to form a fixing end, and the magnesium reinforcing rib comprises reinforcing rib bundles and magnesium cement paste solidified in gaps of the reinforcing rib bundles. According to the integrated sand stabilization plate and the preparation method and sand stabilization method thereof, the integrated sand stabilization plate is high in strength, can be continuously recycled during application, and is not influenced by terrains.

Description

technical field [0001] The invention relates to the technical field of desertification control, in particular to an integrated sand-fixing board, a preparation method thereof, and a sand-fixing method. Background technique [0002] my country is one of the countries most seriously harmed by desertification, and the losses caused by desertification are as high as hundreds of billions of yuan every year. In order to control desertification, the country has spent a lot of money and manpower for a long time, and has achieved considerable results. At present, hundreds of desert control technologies and sand prevention models have been explored. The sand fixation measures are to seal the sand source and inhibit the movement of quicksand, so as to reduce or eliminate the damage to roads, railways and other facilities in the desert. Among them, the relatively mature sand fixation methods are chemical sand fixation and physical sand fixation. [0003] Chemical sand fixation refers ...
