Abstract
Device is fixed sand in three -dimensional sand prevention, mainly constitute by a plurality of geonet boards and a plurality of quarter bend stand, the quarter bend stand includes underground portion and ground top, the underground portion is fixed at the below ground, ground top sets up a plurality of accesses, the quarter bend stand is with vertical and horizontal align to grid, every geonet board sets up a plurality of squares form space, geonet board both ends are fixed on the quarter bend stand through the clamping piece respectively with the bolt, geonet board and quarter bend stand are constituteed portraitlandscape vertical cross and are formed a plurality of check that fix the sand. The utility model discloses have portraitlandscape vertical cross's square form sand -protecting barrier structure, otter board intensity is big, can resist the sand blown by the wind load effectively, and dismountable back used repeatedly sparingly fixes the sand the material, does benefit to the environmental protection, can effectively stablize the ground grains of sand, forms relatively stable vegetation growing environment. The wide application is in railway, highway, municipal administration, sand blown by the wind prevention and cure project such as trees have been planted to fix the sand.
Description
Technical field
The utility model relates to Feng Shagu woods technical field, is specifically related to a kind of three-dimensional preventing and fixing sand device.
Background technology
In highway, railway, municipal administration in the area such as desert, Gobi desert, oasis edge, trees have been planted to fix the sand projects such as engineering, traditional sand fixation material mainly adopts net, tree branches, lath, crop tangerine bar, faggot, reed, the stem or leaf of cattail, shrub branch, sandbag etc., deposit the restriction of its transport of material by objective condition, application life be short, environment pollution is serious, fireproof performance is poor, engineering cost is high, can not reusable shortcoming.
Utility model content
The utility model provides a kind of three-dimensional preventing and fixing sand device, with solve the application life that prior art exists short, can not reuse, fire line difference and the problem of inefficiency.
The utility model solves the technical scheme that its technical problem adopts:
A kind of three-dimensional preventing and fixing sand device, primarily of some geotechnological web plates and some quarter bend columns composition, quarter bend column comprises under ground portion and overground part, under ground portion is fixed on below ground, overground part arranges some adjusting holes, and quarter bend column is evenly distributed with vertical and horizontal, and each geotechnological web plate arranges some grid-like spaces, geotechnique web plate two ends are fixed on quarter bend column with bolt respectively by intermediate plate, and geotechnological web plate and the square crossing of quarter bend column composition portraitlandscape form some lattice that fix the sand.
The utility model geotechnique web plate take HDPE as raw material, extruded by rotation film head after melting, again through traction, cooling, a kind of screen cloth plate body that sizing is formed, geotechnique's web plate is by quarter bend column, intermediate plate and bolt composition are indulged, the grid-like sand blocking net of horizontal square crossing, the motion state of dust storm air-flow is changed by grid-like space, the separation of boundary-layer, recirculating zone size etc. affects Structure of wind-Sand Flow, along with the increase in grid-like space, eddy airstream after sand-protecting barrier will be restricted, the direct ride-through capability affecting the grains of sand, but also the Turbulent characteristics of air-flow before and after the sand-protecting barrier web plate changing grid-like distribution, finally vital impact is produced on its protection benefit, quarter bend column arranges some adjusting holes, when in three-dimensional preventing and fixing sand web plate grid, sand acquires a certain degree, by regulating setting height(from bottom), make dustproof effect optimum, and operate simple and easy.
The utility model has the grid-like sand-protecting barrier structure of portraitlandscape square crossing, and web plate intensity is large, can effectively resist dust storm load; reuse after dismountable, save sand fixation material, be beneficial to environmental protection; can effectively stablize the ground grains of sand, form metastable vegetation growth environment.In the dust storm prevention and cure project such as be widely used in railway, highway, municipal administration, trees have been planted to fix the sand.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model quarter bend column;
Fig. 3 is the structural representation of the utility model intermediate plate.
1 geotechnological web plate in figure, 2 quarter bend columns, 3 intermediate plates, 4 fix the sand lattice, 11 grid-like spaces, 21 under ground portions, 22 overground parts, 23 adjusting holes, 31 fixing holes.
Detailed description of the invention
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of three-dimensional preventing and fixing sand device, form primarily of some geotechnological web plates 1 and some quarter bend columns 2, quarter bend column 2 comprises under ground portion 21 and overground part 22, under ground portion 21 is fixed on below ground, overground part 22 arranges some adjusting holes 23, quarter bend column 2 is evenly distributed with vertical and horizontal, each geotechnological web plate 1 arranges some grid-like spaces 11, geotechnique web plate 1 two ends are fixed in the adjusting hole 23 of quarter bend column with the fixing hole 31 that bolt is each passed through intermediate plate 3, geotechnique's web plate 1 and quarter bend column 2 form portraitlandscape square crossing and form some lattice 4 that fix the sand.
The utility model geotechnique web plate take HDPE as raw material, extruded by rotation film head after melting, again through traction, cooling, a kind of screen cloth plate body that sizing is formed, geotechnique's web plate is by quarter bend column, intermediate plate and bolt composition are indulged, the grid-like sand blocking net of horizontal square crossing, the motion state of dust storm air-flow is changed by grid-like space, the separation of boundary-layer, recirculating zone size etc. affects Structure of wind-Sand Flow, along with the increase in grid-like space, eddy airstream after sand-protecting barrier will be restricted, the direct ride-through capability affecting the grains of sand, but also the Turbulent characteristics of air-flow before and after the sand-protecting barrier web plate changing grid-like distribution, finally vital impact is produced on its protection benefit, quarter bend column arranges some adjusting holes, when in three-dimensional preventing and fixing sand web plate grid, sand acquires a certain degree, by regulating setting height(from bottom), make dustproof effect optimum, and operate simple and easy.Three-dimensional preventing and fixing sand web plate intensity is large, is more than 10 times of common sand proof net intensity, can effectively resists dust storm load.Ageing resistace and application life are more than 3 times of common sand proof net, and once construct, Long-Time Service, comprehensive cost is better than all kinds of common Sand-fixation net material.Three-dimensional preventing and fixing sand web plate, with vertical, horizontal arrangement mode, is vertically assembled formation by connection fastener and is fixed the sand lattice, easy to assembly, saves productivity.The every 10-15 rice of three-dimensional preventing and fixing sand web plate vertical, horizontal is fixed on ground, and fixed point is few, saves immobilization material and duration, and expense reduces; Speed of application is fast, and erecting tools is simple and easy, easy to maintenance, saves maintenance cost.Reuse after three-dimensional preventing and fixing sand web plate is dismountable, save sand fixation material, be beneficial to environmental protection.Geotechnological web plate adjusting hole reserved by the quarter bend column adopted, and when sand acquires a certain degree in three-dimensional preventing and fixing sand web plate grid, by regulating setting height(from bottom), making dustproof effect optimum, and operating simple and easy.Particular design bolt mounting holes can insert easily and take out, and bolt is installed, and dismounting is convenient.
