Abstract

The utility model belongs to the screen technology field and discloses a sand fixing network which is formed by overlapping at least two layers of screens which are formed from organzine and weft. The orifice of the screen is between 0.5cm and 1.0cm. Provided with small net holes, the sand fixing network covers and is fixed on ground which is planted with vegetations. Plants and grasses can escape from the net holes to form a fixed grass cover. Therefore, the using of the sand fixing network structure is beneficial to the formation of the ground grass cover and can promote the conservation of both moisture and soil. And the sand fixing network also has the characteristic of low using cost.

Description

A kind of Sand-fixation net

Technical field

The utility model belongs to silk screen technique field, relates in particular to a kind of Sand-fixation net that is used for prevention soil and water loss, protection vegetation.

Background technology

Control desertification and soil erosion promote that desert afforestation and water and soil conservation are two key subjects in the present environmental protection, and country will drop into huge fund every year and implement.Carry out desert afforestation at present and prevent erosion the measures of adopting more for the various shrubs of plantation, plant or grass on desert or exposed soil by etc., but the shrub of being planted, plant or grass are washed out by as easy as rolling off a log being blown away with big flood by strong wind, and the grass on the grassland of environment fragility and the exposed soil is connected root by cattle and sheep easily again and gnaws and desertification.

The utility model content

The purpose of this utility model has Sand-fixation net simple in structure, as can be carried out effective protection to the grass on the soil with regard to providing.

To achieve these goals, the technical solution adopted in the utility model is:

A kind of Sand-fixation net is connected the net stack by the two-layer at least silk that is formed by organizine and tram and constitutes.

Its additional technical feature comprises:

The organizine of described formation silk screen is vertical mutually with tram;

The organizine of described adjacent layer silk screen and tram non-overlapping copies;

Vertical mutually between the organizine of described adjacent layer silk screen one deck and tram, be acute angle-shaped between organizine of another layer and the tram;

The aperture of described silk screen is between 0.5-1.0 centimetre.

Sand-fixation net provided by the utility model compared with prior art, have the following advantages: because this net is made of the two-layer at least silk screen stack that is formed by organizine and tram, formed this Sand-fixation net has less mesh, be covered in it large tracts of land on the ground that kind is implanted with vegetation and fix, plant, little grass can get out from mesh, after growing certain root system, seedling just can form immobilized careless quilt, therefore the use of this structure Sand-fixation net helps the formation of ground grass quilt, and promotes the maintenance of water and soil; This Sand-fixation net in use not only can not influence the growth of careless quilt, even if cattle and sheep are gnawed, because the effect of mesh also can avoid grass to be uprooped, thereby grass has been played the effect of protection.

Description of drawings

Fig. 1 provides the structural representation of Sand-fixation net for the utility model;

Fig. 2 is the structural representation of second kind of Sand-fixation net.

The specific embodiment

The structure of the Sand-fixation net that the utility model is provided below in conjunction with accompanying drawing is described in further details.

As shown in Figure 1, the structural representation of the first kind of Sand-fixation net that provides for the utility model.Promptly this Sand-fixation net is connected and fixed the silk screen 1,2 and 3 that is superimposed by three layers by anchoring filament 10 and constitutes, and each layer silk screen formed by orthogonal organizine 4 and tram 5.In order further to reduce to make the organizine and the tram non-overlapping copies of adjacent layer silk screen by organizine and the formed mesh of tram.

The silk screen number of plies that constitutes Sand-fixation net is generally selected according to the field of employment and the application target of this Sand-fixation net: when being used in desert area for fixing the sand the time spent, then can select between three layers to four layers, the mesh of the feasible Sand-fixation net that constitutes is smaller as far as possible, thereby can effectively stop flowing of the grains of sand, promote the formation of careless quilt; When being used to stop soil erosion,, therefore can use silk screen fixed overlay two-layer or three layers to constitute Sand-fixation net because the viscosity of soil is bigger when being used in non-desert region.

The mesh aperture 9 of above-mentioned formation Sand-fixation net silk screen generally designs between 0.5-1.0 centimetre, can make the formation best results of careless quilt: the growth that had both helped careless quilt forms, and helps fixing to the grains of sand again, and preparation and use cost are also minimum.

In order to reduce the silk screen number of plies that constitutes Sand-fixation net, as shown in Figure 2, the

organizine

4 and 5 of the trams of adjacent layer silk screen one deck 6 can be designed to mutual vertical stratification, the mesh 7 that organizine of another layer 8 and tram constitute is designed to be the diamond shaped of acute angle.

Claims

1, a kind of Sand-fixation net is characterized in that: be connected stack by the two-layer at least silk screen that is formed by organizine and tram and constitute.

2, a kind of Sand-fixation net according to claim 1 is characterized in that: the organizine of described formation silk screen is vertical mutually with tram.

3, a kind of Sand-fixation net according to claim 2 is characterized in that: the organizine of described adjacent layer silk screen and tram non-overlapping copies.

4, a kind of Sand-fixation net according to claim 1 is characterized in that: vertical mutually between the organizine of described adjacent layer silk screen one deck and tram, be acute angle-shaped between organizine of another layer and the tram.

5, according to claim 1,2,3 or 4 described a kind of Sand-fixation nets, it is characterized in that: the aperture of described silk screen is between 0.5-1.0 centimetre.
