Net covering structure for slowing down burying of sand blocking net by moving dune

Abstract

The invention relates to the field of road protection, in particular to a covering net structure for slowing down burying of sand blocking nets by a moving dune, the covering net adopts an anti-aging nylon woven net with the porosity of 55%, the aperture of 1.5 mm * 1.5 mm and the wire diameter of 0.5 mm, the covering net is arranged between two sand blocking nets and extends to a windward side slope toe of the sand dune in front of the sand blocking nets, and the edge is fixed by a No.1 bamboo drill rod with the length of 1 m; the fixing range is 9 m away from the edge of the covering net, the middle of the covering net is densified through a second bamboo drill rod with the length of 0.5 m, different covering nets are connected by 20 cm in an overlapped mode, and the overlapped portion is fixed through a first bamboo drill rod. The sand dunes in front of the sand blocking nets are covered with the covering nets, contact between sand grains and air flow is reduced, the effect of preventing the moving sand dunes from moving to bury the sand blocking nets is achieved, the covering nets cover the space between the first sand blocking net and the second sand blocking net, and the moving sand dunes can be further prevented from moving to bury the sand blocking nets.

Description

Technical field [0001] The present invention relates to the field of road protection, specifically to a networked structure that slows down the flow of sand dunes to bury and obstruct sand mesh. Background [0002] At present, the road protection system is usually based on sand obstruction, sand fixation, sand transport and sand conduction measures, using a multi-belt integrated protection mode, composed of various sand barriers, the first measure is usually HDPE grid plate or high vertical sand barrier based on sand obstruction measures, the second measure is usually grass square and low vertical sand barrier based on sand fixation measures, and then plant sand fixation based on sand fixation system, in different areas correspondingly use sand transport, sand diversion and other different measures; the operation of the road sand disaster statistics can be found, The protection system can prevent the desert road sand damage phenomenon to a large extent, but in the actual applica...

Problems solved by technology

[0003] In the patent of mobile desert area with publication number CN204919521U, three measures are used to control the mobile desert, which can effectively prevent sand dunes from moving, but the three methods are used at the same time, the cost is high, and the feasibility needs to be further discussed
