Problems solved by technology

[0004] Chinese patent CN 1159499c discloses that physical-chemical-plant sand control is effective, but the comprehensive labor cost is high, especially the use of grass grids, the comprehensive labor cost is high, and the efficiency is low, which is not conducive to large-scale promotion
[0005] In addition, people also adopt chemical methods to fix sand, such as spreading a layer of protective film with a certain strength on the sand surface with cementing materials, so as to isolate the direct effect of airflow on the sand layer. Until the early 1970s, the Ministry of Railways of my country scientifically studied The Northwest Research Institute of the Academy carried out emulsified asphalt sand fixation along the Baolan Railway. It sprayed emulsified asphalt on a large area and cooperated with the experimental research of planting sand-fixing plants. Crispy and soft in summer, not practical
[0006] At present, in terms of sand fixation and sand control, to be precise, it still stays on surface treatment. It cannot prevent sand, fix sand, and make deserts grow vegetation to form a good ecological environment. In addition, the cost of sand control has not been widely promoted. application

Embodiment 1

[0028] Get 246 grams of clean water, add 3 grams of RC-YSFRHJ805 type anionic emulsifier (commercially available product) in water, 0.25 grams of MgCl , 0.3 grams of fatty acid polyoxyethylene ether sodium sulfate, 0.25 grams of acrylic acid gelatin, 0.2 grams of urea, Stir evenly in the agent tank, then raise the temperature of the emulsifier aqueous solution to 65°C, and keep the temperature of the emulsifier aqueous solution at 65°C, while heating 250 grams of straight asphalt A (its properties are shown in Table 1) to 135°C, Add the prepared emulsifier aqueous solution into the colloid mill (rotation number 4900 rev / min) at the same time, process through the colloid mill for 2 minutes, add 50 grams of anion chloroprene latex and 100 grams of anion SBR latex in the configuration tank and stir evenly to obtain The results of the quick-spraying quick-setting polymer water-based asphalt nutrient solution are shown in Table 2. As can be seen from Table 2, the polymer water-base...

Embodiment 2

[0036] Add 213.25 grams of clean water into the preparation tank, first add 6 grams of medium cracking emulsifier RC-MFRHJ802 into the water, and add 0.25 grams of NH 4 Cl, 0.3 gram of carboxymethyl cellulose, 0.2 gram of desugared sodium lignosulfonate (M-9), heat the emulsifier aqueous solution to 65°C, then add 10 grams of SBS latex, mix well and set aside.

[0037] Take 270 grams of solvent-deoiled asphalt B, heat it to about 135 ° C, and completely melt it into a liquid state, then add it to the colloid mill at the same time as the prepared emulsifier aqueous solution (rotation number 4900 rpm), and after 2 minutes, a polymerization Water-based asphalt nutrient solution. The results are shown in Table 3.

[0038] It can be seen from Table 3 that the storage stability of the modified asphalt nutrient solution is very ideal, the softening point, viscosity and toughness are much higher than the raw asphalt, and the service life of the polymer water-based asphalt is improved...

Embodiment 3

[0040] Add 199 grams of clean water into the preparation tank, first add 7.5 grams of medium slow cracking and fast setting emulsifier (RC-SFRHJ802) into the water, and add FeCl while stirring 3 0.2 grams, 0.45 grams of polyvinyl alcohol, 0.25 grams of DDA-881 dispersant, 0.1 grams of ammonium bicarbonate, heat the emulsifier aqueous solution to 65 ° C, then add 12.5 grams of EVA latex and stir evenly before use.

[0041] Take 280 grams of oxidized asphalt C, and heat it to 135°C at the same time. After the hot asphalt is completely melted, add it to the colloid mill together with the above mixed solution (rotation number: 4900 rpm), and process for 2 minutes to obtain polymer water-based asphalt nutrient solution. The results are shown in Table 3.

[0042] It can be seen from Table 3 that the stability of polymer water-based asphalt nutrient solution is still good, and its viscosity and toughness are much higher than that of raw asphalt, which is conducive to the formation o...

Abstract

The invention relates to a gridding cloth-asphalt film-ecological comprehensive sand prevention and control method. The method comprises: planting plant seeds which have been soaked in a nutrition liquid in sandy land or desertified land, mechanically covering a gridding cloth on the land and fixing the gridding cloth, using a fast-spraying-fast-drying polymer waterborne asphalt nutrition liquid to mechanically spray on the covered gridding cloth, to form a 0.2-2 mm protection film, to play a role of soil moisture conservation, and form a good ecological environment which is suitable for the plants to grow. Thus, a desert becomes an oasis. All process of the method can apply fully-automated operation, comprehensive cost is low, and efficiency is high. The method is a fast, efficient, and brand new ecological sand prevention and control method.

Description

technical field [0001] The invention relates to a new technical field of sand prevention and control, in particular to a grid cloth-asphalt film-ecological comprehensive sand control method. technical background [0002] With the warming of the earth's climate, frequent human activities and increasingly serious damage, the desertification of the earth is increasingly affecting people's living environment. In 2014, the total area of ​​desertified land in the country was 1.7397 million square kilometers, accounting for 18.12% of the total land area, distributed in 498 counties (banners, cities) in 18 provinces and cities including Inner Mongolia, Tibet, Shaanxi, Gansu, Qinghai, and Ningxia. The environment in a larger area will cause disasters, and the complete eradication of sand disasters has become an urgent problem for countries all over the world to solve. [0003] Large-scale land desertification is the cause of sandstorms, and it is an important factor for soil erosion...
