Novel method for stabilizing and controlling sand by multifunctional windbreak wall

Abstract

The invention provides a novel method for stabilizing and controlling sand by a multifunctional windbreak wall. Sandbag type windbreak walls or precast concrete beam column steel string structure cement composite plate walls are adopted at different positions of desert areas so as to break wind and stabilize sand, gypsum is used for stabilizing sand, the deserts are greened and beautified by combining dripping irrigation with sprinkling irrigation, and measures are adopted to suit local conditions. The method is low in cost, has one-time investment and long-time benefit, and contributes to controlling the sand in a large area and greening the deserts.

Description

technical field [0001] The patent of the present invention relates to a new method for sand-fixing and control of multifunctional windshield walls, which belongs to the field of desert control Background technique [0002] Existing methods of desert control include: traditional wheat-grass grids for sand control; tree planting; fences to keep out the wind and other technologies. Abroad, there are asphalt spraying adhesion method, chemical adhesive adhesion method, grass mat laying method, drip irrigation method, etc. There are cement-yellow-sand composite hard shell fully enclosed sand control methods, mobile sprinkler irrigation and other technologies. Among these methods, the traditional wheat straw grid sand control has a history of more than 50 years, and it is a very effective method for sand control within a certain range. , but did not solve the problem of surface flow, sand fixation, water retention and durability. Generally, it is replaced once every 1-2 years; affo...

[0002] Existing methods of desert control include: traditional wheat-grass grids for sand control; tree planting; fences to keep out the wind and other technologies. Abroad, there are asphalt spraying adhesion method, chemical adhesive adhesion method, grass mat laying method, drip irrigation method, etc. There are cement-yellow-sand composite hard shell fully enclosed sand control methods, mobile sprinkler irrigation and other technologies. Among these methods, the traditional wheat straw grid sand control has a history of more than 50 years, and it is a very effective method for sand control within a certain range. , but did not solve the problem of surface flow, sand fixation, water retention and durability. Generally, it is replaced once every 1-2 years; afforestation is a better way to control sand, but it cannot be realized in places where water is scarce; although fences can play a role in wind protection. It can play the role of local wind protection, but it cannot solve the problem permanently; asphalt spraying adhesion method and chemical adhesive adhesion method are not advisable methods to control deserts. Grass mat laying method is a better method, but it is not handled properly and is easy to It was blown by strong winds to form loopholes; drip irrigation is an advanced technology that has been successfully researched abroad, and mobile sprinkler irrigation is also an effective method, but there are some problems in desert control on a large scale, and the problems of sand control and greening have not been fundamentally solved
