Embodiment 1

[0040] Embodiment one: this chemical method of changing the fragile ecological environment in the loess area and increasing arable land, the method operation steps are as follows in turn:

[0041] ① Bulldoze and level the mounds, plateaus, beams, etc. that need to be improved;

[0042] ② Measure the compactness, permeability coefficient and water content of the loess before improvement;

[0043] ③Spray the polymer liquid grouting material 2 on the site to be improved, and the grouting material 2 has water resistance after solidification. According to the grouting material 2, it takes 2 minutes to seep to the predetermined position. The grouting material 2 is selected as cement slurry, and the water-cement ratio of the cement slurry is determined. 2, the cement slurry seeps down along the vertical columnar joints 1 of the loess, and when it penetrates into the predetermined position under the surface, the cement slurry expands and solidifies rapidly, thus blocking the vertical ...

Embodiment 2

[0047] Embodiment two: this chemical method of changing the fragile ecological environment in the loess area and increasing arable land, the method operation steps are as follows in turn:

[0048] ① Bulldoze and level the mounds, plateaus, beams, etc. that need to be improved;

[0049] ② Measure the compactness, permeability coefficient and water content of the loess before improvement;

[0050]③Spray the polymer liquid grouting material 2 on the site to be improved, and the grouting material has water resistance after solidification. According to the grouting material 2, it takes 1 min to penetrate to the predetermined position. The grouting material 2 is selected as cement slurry, and the water ash of the cement slurry is determined. When the ratio is 4, the cement slurry seeps down along the vertical columnar joints 1 of the loess. When it penetrates into the predetermined position under the surface, the cement slurry expands and solidifies rapidly, thus blocking the vertic...

Embodiment 3

[0054] Embodiment three: this chemical method of changing the fragile ecological environment in the loess area and increasing arable land, the method operation steps are as follows in turn:

[0055] ① Bulldoze and level the mounds, plateaus, beams, etc. that need to be improved;

[0056] ② Measure the compactness, permeability coefficient and water content of the loess before improvement;

[0057] ③The polymer liquid grouting material 2 is sprayed on the site to be improved, and the grouting material has water resistance after solidification. According to the grouting material 2, it takes 30 seconds to penetrate to the predetermined position. The grouting material 2 is selected as cement slurry, and the water ash of the cement slurry is determined. When the ratio is 5, the cement slurry seeps down along the vertical columnar joints of the loess. When it penetrates into the predetermined position under the surface, the cement slurry expands and solidifies rapidly, thus blocking...

Abstract

The invention discloses a chemical method for changing the weak ecological environment of a loess area and increasing the arable land. The method includes the steps of firstly, bulldozing and leveling loess hills, table lands, ridges and other places needing to be improved; secondly, measuring the before-improvement compactness, permeability coefficient and water content of loess; thirdly, conducting sprinkling-irrigation of a grouting material on the places needing to be improved, wherein the grouting material infiltrates downwards along perpendicular columnar jointing of loess, and when reaching a preset underground position, the grouting material rapidly expands and cures so as to block the perpendicular columnar jointing so that the effect of a water-resisting layer can be achieved; fourthly, the water content of improved soil is increased, so the water molecules of the soil can infiltrate and break the microstructure and perpendicular columnar jointing of loess, and the permeability or permeability coefficient of the improved soil is tested; fifthly, the water content of the improved soil is detected, and plantable plants are determined. The method has the advantages that the microstructure of soil is changed, water can infiltrate the structure of the soil, and the weak ecological environment of the loess area is effectively improved.

Description

technical field [0001] The invention relates to a method for changing the fragile ecological environment in the loess area and increasing arable land, in particular to a chemical method for changing the fragile ecological environment in the loess area and increasing the arable land. Background technique [0002] In northern China, the Loess Plateau starts from the Taihang Mountains in the east, extends to the Wushao Mountains in the west, connects to the Qinling Mountains in the south, and reaches the Great Wall in the north. It mainly includes Shanxi, Shaanxi, and parts of Gansu, Qinghai, Ningxia, Henan and other provinces. The world's largest loess accumulation area. The loess is 50-180 meters thick, the climate is relatively dry, the precipitation is concentrated, the vegetation is sparse, and the soil erosion is serious. [0003] The three major landform types of mountain, plain and Sichuan are the main body of the Loess Plateau. The original (or plateau) refers to the...
