A sand-based sand-fixing barrier and its preparation method

Abstract

The invention provides a sand base sand solidification barrier and a preparation method thereof and belongs to the field of sand controlling. The sand base sand solidification barrier is prepared from desert sand, light burning powder, polyacrylate and a first solution, wherein the first solution refers to a magnesium sulfate aqueous solution, a monopotassium phosphate aqueous solution or a magnesium phosphate aqueous solution. The preparation method includes the steps that the desert sand, the light burning powder, the polyacrylate and the first solution are mixed by weight part for a reaction at 25-60 DEG C for 10-20 min to form reaction materials, and a sealing reaction of the sealing materials is conducted at 20-30 DEG C for 20-24 hours. The preparation method is simple in process, mild in reaction condition and low in cost. The sand base sand solidification barrier is applied to a sand prevention and sand controlling project, and the constructional difficulty and the construction cost can be effectively reduced. Moreover, the degradation resistance of the sand base sand solidification barrier is good and long in service life and can effectively prevent the movement of quicksand.

Description

technical field [0001] The invention relates to the field of sand control, in particular to a sand-based sand control barrier and a preparation method thereof. Background technique [0002] Sandy desertification (desertification for short) is a process of land degradation caused by the combination of irrational human activities and changes in natural conditions. During this process, land productivity is greatly reduced, and even becomes unusable land, causing sandstorms, sandstorms and other disasters, seriously endangering industrial and agricultural production, and reducing people's quality of life. [0003] At present, in order to prevent and control sand, the most widely used method is to set up sand barriers. Traditional sand barriers are mainly made of grass squares and stone squares. However, the degradation resistance of the grass grid is poor, and often after 2 to 3 years of use, the grass grid sand barrier will rot and other phenomena, which cannot effectively bl...

AI Technical Summary

Problems solved by technology

However, the degradation resistance of the grass grid is poor, and often after 2 to 3 years of use, the grass grid sand barrier will rot and other phenomena, which cannot effectively block the movement of wind and sand; The deterioration resistance of the grid is better, but the construction cost of the stone grid is high. For example, in the sand control along the railway or highway, the vertical protection range is often required to be as long as hundreds of meters, which makes the laying area of ​​the stone grid huge. high cost
