Low-degree-of-coverage wing bag sand barrier

Abstract

The invention discloses a low-degree-of-coverage wing bag sand barrier. The low-degree-of-coverage wing bag sand barrier comprises a sand bearing base film. The inner wall of the sand bearing base film is provided with an elastic cross strip array composed of elastic cross strips. One ends of the elastic cross strips are provided with a first lock catch array composed of first lock catches, and the other ends of the elastic cross strips are provided with a second lock catch array composed of second lock catches. The second lock catches are connected with the first lock catches in a buckle-press manner. The low-degree-of-coverage wing bag sand barrier has the following beneficial effects that a user can adjust the height of the sand barrier autonomously according to the terrain, the wind power and wind speed conditions of construction sites, the purposes of changing the profile of the wind speed of sand-driving wind and reducing the grounding wind speed are achieved, and accordingly the purpose of fixing sand dunes is achieved more effectively; and the sand barrier is buried 3-5 years later, it is indicated by the sand dunes that stable soil crusts and vegetation are formed, the sand barrier is degraded gradually, and the pollution and damage to the environment are avoided.

Description

technical field [0001] The invention relates to a sand damage control device, more precisely, a low-coverage wing bag sand barrier. Background technique [0002] In the long-term practice of controlling sand damage in my country, we have invented engineering sand-fixing measures that use various materials (wheat straw, reeds, clay and gravel, etc.) to make barriers on the sand surface to fix the surface of quicksand. shape. Ribbon sand barriers are mainly used to prevent and control sand damage caused by relatively single wind direction, while lattice sand barriers are mostly used to prevent and control sand damage caused by multi-directional winds. Its main principle is to change the sand movement conditions by changing the properties of the underlying surface and increasing the surface roughness. [0003] Large-area sand barriers have remarkable sand-fixing effects, but usually require the cooperation of sand-blocking measures. Generally, sand-blocking fences are used to ...

AI Technical Summary

Problems solved by technology

However, due to the different conditions such as terrain, wind speed and sand material composition in the sandy area, and the passage of time for setting up sand barriers, some problems and defects have also been exposed in the existing sand barriers: ①The existing vertical sand barrier protection materials are relatively hard, and the test It is proved that sand barriers with flexible and elastic materials are more effective, but suitable materials are expensive and inconvenient to process and transport. For example, commonly used materials such as wheat straw, reeds, clay, gravel, etc. are not suitable for raising in sandy areas and cannot be made. ②The existing sand barriers will be affected by factors such as sand burial and material decay and damage over time, which will reduce their sand-fixing effectiveness; ③The technical system of the existing sand barrier deployment is relatively chaotic, and there is no unified Material and corresponding geological and climatic conditions layout technical regulations; for example, the height of the sand barrier layout is fixed, and the effect of changing the wind speed profile of sand-emission wind at different wind speeds and weakening the wind speed near the ground is different
