Abstract

The utility model relates to a plastic sand-preventing net, which is a wind-proof sand-fixing device for improving regional economy and preventing sand to protect the ecologic environment. The utility model is characterized in that the net is a high rigidity plastic net comprising meshes and net diameters. The meshes are in random arrangement and shaped in ellipses, or circle, or polygon. The net diameters are entities with flattened or round shape, and the upper portions of the net diameters are equipped with reinforced ribs. The utility model is used to make continuous aperture sediment barrier or wind barrier, can carry out stabilizing treatment to the dune zone, and lower the wind speed, thereby the sands fall off from the suspended state, and stack on the leeward side of the wind barrier to form a second barrier layer. The high rigidity sand-proof net not only can be employed to make sand-preventing multi-stage dividing strips on the highway and the railway, thereby preventing the highways and the railways in the desert from inundating by the floating sands, but also can prevent sand from moving in the zone where sands can rise easily. Desert vegetation can be planted on the sands to fix the sands, and oasis can be built in the desert, thereby having more operation significance to prevent and control sand.

Description

Plastic sand preventing net

Technical field the utility model relates to a kind of to improving regional economy, the facility of checking winds and fixing drifting sand---the Plastic sand preventing net of defending and controlling sand and preserving the ecological environment.

The background technology desertification and the deterioration of the ecological environment that is caused thereof constitute a serious threat to China's ecological safety and economic development.Desertification is as global great environmental problem, will become one of 21 century the severeest problem of being faced with development of human survival.Defend and control sand to ecological, environmental protective, improve regional economy and be significant.The conventional method of checking winds and fixing drifting sand is to go up windproof hedge with the wicker folder, establishes straw checkerboard barrier with straw at surface, sand dune bundle then in hedge, spreads grass seeds at last in straw checkerboard barrier.This method cannot stand the dust storm etch because of material therefor, and all will repeatedly repeat to press from both sides hedge, water caltrop grid every year, takes a lot of work, takes material, and vegetation recovery is very undesirable.

Summary of the invention the utility model provides a kind of alternative wicker hedge, straw checkerboard barrier, reduce labour cost, improve the effect of checking winds and fixing drifting sand, have fixedly moving dunes, can reduce effects such as wind erosion desertification and the vegetation recovery of promotion sand ground, and can reusable Plastic sand preventing net.

The utility model Plastic sand preventing net content Description:

The utility model Plastic sand preventing net is characterized in that: be a kind of highstrenghtpiston's net, be made of mesh and net footpath; Mesh is irregular alignment, is shaped as ellipse, circle or polygon-shaped hole; The net footpath is to be flat and circular entity, and reinforcing rib is arranged in the above.

The utility model Plastic sand preventing net is used to build a continuous porous sediment trapping barrier or blocks air partition, can stablize processing to the area, sand dune.The sediment trapping barrier can resist wind speed, and the grains of sand are fallen from suspended state, and is deposited in sediment trapping barrier leeward side, forms the second road obstacle.Adopt high strength sand proof net construction sand prevention multistage at highway, railway, can also prevent effectively that blown sand from flooding the highway of desert region, railway every band.The utility model Plastic sand preventing net can given birth to easily slack and play a husky area, prevents that the sand dune from moving, and plants desert plant on the sand dune, as sand sagebrush (Artemisia filifolia), leaflet golden pheasant, mangosteen etc., vegetation is fixed the sand, in the desert, build the oasis, have very realistic meanings to defending and controlling sand.In the utility model Plastic sand preventing net product, added age resister, had characteristics such as corrosion-resistant, anti-aging, broad application temperature range, used-60～+ 100 ℃ the time applicable to temperature.

Description of drawings Fig. 1 is the Plastic sand preventing net structural representation

Among Fig. 1: 1 is that mesh, 2 is the net footpath

Specific embodiment the utility model Plastic sand preventing net is achieved in that sees Fig. 1, and highstrenghtpiston's net is to be made of mesh 1 and net footpath 2; Mesh 1 is irregular alignment, is shaped as oval and polygon-shaped hole: net footpath 2 is entities of circular and flat, and reinforcing rib is arranged in the above.Be the characteristics such as corrosion-resistant, anti-aging, broad application temperature range that improve the high strength sand proof net; in raw materials for production, added age resister; this product is used for vegetation and fixes the sand and be used to defend and control sand to preserve the ecological environment applicable to the area of temperature at-60～+ 100 ℃.
