Abstract

The utility model relates to a plastic warp knitting grid net for soil and water conservation, which adopts that double warp knitting machines heat, cut and stretch to form thin film warp woof flat yarns which are knitted into a plastic warp knitting grid net. The utility model is characterized in that the warp direction is provided with a warp flat yarn coiling (1), and the woof direction is composed of roots of film flat yarn weft insertions (2); the warp direction and the woof direction form a plurality of square holes or ladder-shaped holes (4) which are knitted and chained into a double layers of net bodies (3) structure. The coverage of porosity is from 40 to 60 present, and the plastic warp knitting grid net with a plurality of square holes or ladder-shaped holes (4) is favorable to soil and water detention, wild plant seed persistence, natural vegetation growth restoration and soil and water conservation. The utility model has the advantages of convenient and simple construction, long service life, low cost and favorable effect of soil and water conservation and is favorable to application and extension of large areas of bare grounds of soil and water loss.

Description

A kind of plastic warp knitted grid

One, technical field

The utility model relates to the plastic warp knitted grid that a kind of water and soil conservation is used.

Two, background technology

Prevention and control of soil erosion at present is to extrude through melting with thermal resin to be bonded to net, and the attached artificial grass planting product of planting living band, filling up made from nonwoven fabric, grass seeds, base-material, fertilizer carries out the grass planting recovery, though this plantation production product effect is good, but production, construction, maintenance project sword are big, production use cost height can't be in the river, the applying of river, reservoir middle and upper reaches small watershed and Chinese and Western area large tracts of land soil erosion open ground.

Three, summary of the invention

The technical problems to be solved in the utility model provides and a kind ofly implements water and soil conservation with river, River Reservoir middle and upper reaches area small watershed and central and west regions large tracts of land soil erosion open ground and be resumed low-cost low, the easy construction of usefulness, the plastic warp knitted grid of long service life with natural plants.

The technical scheme of the utility model plastic warp knitted grid is to mix with age resister to extrude with high polymer to blow out the film volume, adopting the double rib warp loom of extraordinary ISO configuration to add thermal cutting draws and stretches into film warp, latitude flat filament, is woven into plastic warp knitted grid, it is characterized in that warp-wise is film flat filament lopping (1), broadwise is that many flat filament inlaid thread (2) constitute, constitute several square openings or trapezoidal hole (4) by warp-wise and broadwise, and become double-deck dictyosome (3) structure.This bilayer dictyosome (3) structure, upper wire with lower net by forming through flat filament lopping (1) and many inlaid thread of film flat filament (2) chaining.The thin coverage rate of this bilayer dictyosome is 40---60%, helping water and soil is detained with the wild plant seed and retains several water and soil conservation warp knitted grids square or trapezoidal hole (4) with the natural vegetation growth recovery, advantage of the present utility model, be to construct simple and convenient, use cost is low, the life-span is long, fixing of soil and conservation of water is effective, the large-area applications of favourable soil erosion open ground is promoted.

Four, Figure of description

Fig. 1 the utility model embodiment schematic diagram

Among the figure: 1, film is through the flat filament rolling; 2, many inlaid thread of film flat filament; 3, double-deck dictyosome; 4, square or trapezoidal hole.

Five, the specific embodiment

Referring to Fig. 1, the utility model embodiment is that a kind of water and soil conservation uses " plastic warp knitted grid " by the longitude and latitude film flat filament that cuts into, adopt the double rib warp loom chaining to become through flat filament lopping (1), many film flat filament inlaid thread (2), levels chaining together becomes double-deck dictyosome (3), it dredges saturating coverage rate is 40---60%, is woven with delay water and soil and wild plant seed and retains and a plurality of square openings of natural vegetation growth recovery and trapezoidal hole.

Claims

1, a kind of plastic warp knitted grid, adopt the double rib warp loom of extraordinary ISO preparation, add thermal cutting and be drawn into film longitude and latitude flat filament, be woven into plastic warp knitted grid, it is characterized in that warp-wise is through flat filament rolling (1), broadwise is that many film flat filament inlaid thread (2) constitute, and constitute several square openings or trapezoidal hole (4) by warp-wise and broadwise, and chaining becomes upper and lower double-deck dictyosome (3) structure together.

2, by the described plastic warp knitted grid of claim 1, it is characterized in that described double-deck dictyosome (3) structure, upper wire with lower net by forming through flat filament chaining lopping (1) and many film flat filament inlaid thread (2) chaining.
