20cm high plastic net sand-protecting barrier device and arranging method

Abstract

The invention discloses a 20cm high plastic net sand-protecting barrier device which comprises a plurality of sand fixing units, wherein each sand fixing unit comprises a 20cm high plastic net and a fixing drill rod; each plastic net is arranged as a V-shaped sand-protecting barrier and a straight sand-protecting barrier through the fixing drill rod; each straight sand-protecting barrier is arranged at an opening of the corresponding V-shaped sand-protecting barrier. The invention also discloses an arranging method for the device. The arranging method for the 20cm high plastic net sand-protecting barrier device and the construction structure are optimized by the invention; a large amount of material cost and labor cost for preventing and treating sand damage in unit area are saved; the construction environment of personnel is improved; the main work is changed into indoor processing from on-site construction; the treating cost for the sand damage in unit area is greatly reduced; the adaptation for the complex terrain of construction site is increased; the method is widely applied to the anticipatory measure for forestation in sand damage area or the independent measure for preventing and treating the sand damage.

Description

technical field [0001] The invention relates to the technical field of engineering sand control, in particular to a 20cm-high plastic net sand barrier device and a setting method. Background technique [0002] Desertification is the most serious ecological and environmental problem in the world today. The continuous expansion of desertification has a serious impact on the ecological security, food security and regional economic and social development in the sandy areas in northern my country and even the country. The annual direct economic loss caused by desertification is nearly 643 billion. The proportion of desertification area in the region is large, and the frequent occurrence of wind and sand disasters seriously affects the regional economic development and human survival. [0003] The control and governance of soil wind erosion and surface wind-sand movement are the main content of desertification control, and the formation and development of soil wind erosion and sur...

AI Technical Summary

Problems solved by technology

However, the construction of the traditional 20cm-high plastic grid sand barrier is based on the construction method of the wheat straw sand barrier, which requires construction personnel to lay it into a continuous 1m×1m grid at the construction site, while the traditional 20cm-high plastic grid Sand barriers are usually fixed with bamboo brazing and iron wires. Not only is the construction process cumbersome, but also because bamboo brazing and iron wires are easy to corrode and rust in the wild, often when the 20cm-high plastic net sand barrier is intact, the sand barriers are usually fixed. The problem makes the sand barrier lose its proper protective effect

The above reasons make the material cost and labor cost per unit area of ​​sand damage prevention and control very high, which seriously limits the implementation of large-scale sand prevention and control projects with 20cm high plastic grid sand barriers.
