Abstract

Disclosed is a giant position type arrangement for checking the wind and fixing the shifting sand. A belt-shaped checking the wind and fixing the shifting sand wall with width 30m to 80m and height of 1.4 m is composed of thousands of press sand tables and wind cylinders which are arranged and combined. The utility model covers and tightly surrounds farmlands, grasslands, railways, highways, oilfield pipelines, aerospace facilities, water conservancy facilities, wet lands, river sources, and the periphery of the desert or sand dunes which lies to the protection building of the antique buildings of the cultural relics. The front row and the back row are mutually staggered into the shape of the labyrinth, and the circumference of the components are left the gaps from 10 cm to 20 cm where trees and grasses are planted; a certain spaces are left under the tables, which is good to store water and to preserve moisture and to perch and to multiply for animals, and which is good to rebuild to ecosystem. Then, the utility model gradually moves to the center of the desert or the sand dune, and ultimately overwhelms desertification. The giant position type arrangement for checking the wind and fixing the shifting sand adopts dies formed by multitudinous pouring concrete, which can defend various natural disasters and man-induced destroy, which can be used for multiple times, and which obtains benefits for multiple years with an investment.

Description

The VLA formula device of checking winds and fixing drifting sand

Affiliated technical field

This is suitable for the novel a kind of ecological environmental protection and technology that prevents and controls desertification of relating to, and refers to the VLA formula device of checking winds and fixing drifting sand especially.

Background technology

Soil and grassland desertification, it is the ecological disaster that the whole world faces, China also is that desertification endangers one of serious area the most, blast that the desert district wreaks havoc and billowing yellow sand, annual oasis, grassland and the farmland wetland that all will eat and fall into oblivion sheet, and approaching to villages and small towns and city step by step, become the biggest threat of industrial and agricultural production and people existence, and seriously restricted the sustainable development of national economy.For many years, people adopt planting trees and grass, build the husky wall of retaining, sediment trapping net and plant engineering measures such as burying straw checkerboard barrier, dust storm is prevented and treated, but because the desert district is extremely arid, the adverse circumstances of the extremely hot severe cold of extreme again, planting trees and grass is difficult to survive, it is very slow to grow, produce little effect in a short time, and construction keeps off husky wall and sediment trapping net and plants and bury straw checkerboard barrier, both needed to expend a large amount of time, the man power and material, but also can only control and stop local drift sand, but be difficult to stop the invasion and attack of billowing sandstorm, more be difficult to stop and control the rapid expansion of desertification and stretch rapidly.

Summary of the invention

This is suitable for novel purpose and provides a kind of VLA formula device of checking winds and fixing drifting sand, the dust storm interception and the compacting in Gobi desert desert district are fixed within the VLA, promote the ramp of vegetation in the zone and the restoration and reconstruction of the ecosystem, thereby effectively stop walking crosswise of drift sand and sandstorm to be wreaked havoc, and thoroughly effect a radical cure the desertification in Wind-sandy Area grassland, forest land, wetland and arable land.

This technical scheme that is suitable for novel technical solution problem is: the VLA formula device of checking winds and fixing drifting sand is by after pressing the husky table and the post two parts that keep out the wind to be assembled into one group one group primary structural component, become tens meters wide by no array primary structural component assembled arrangement again, the several kilometers long VLA formula of the being continuous band of checking winds and fixing drifting sand, tightly surround and cover and withhold around Gobi desert desert and sand dune, the interlaced labyrinth-like that is in front and rear row position, press husky table to leave the slit of 10 20cm all around, but planting trees and grass therebetween, table also leaves the space of 8-16cm down, help retaining and conserveing soil moisture and beneficial organism perch procreation, the post that keeps out the wind vertically inserts in the mortise of pressing husky table, formation is as the rugged windbreak of forest, the effectively invasion and attack of catch blowing sand, promote plant growing, treat that ecosystem restoration in the VLA is rebuild after, the device of can will checking winds and fixing drifting sand moves to Gobi desert desert depth gradually, and drift sand is fixed the most at last, and dust storm and sandstorm are subdued.

This is suitable for novel beneficial effect: the VLA formula checks winds and fixes drifting sand that device has catch blowing sand, reduces wind speed, compacting and regularly surface low sand, retain and conserve soil moisture, regulate ground temperature, promote the function of plant growing, ecology recovering system, for protect the fields, the safe operation of grassland, wetland, forest land and railway, highway, oil field, Aero-Space facility and historical relic ancient building all will bring into play huge benefit.

Description of drawings

Below in conjunction with drawings and Examples this is suitable for novel further specifying.

Fig. 1 is this work schematic diagram that is suitable for novel first embodiment.

Fig. 2 is the husky table structure figure of the pressure of second embodiment.

Fig. 3 is the rod structure figure that keeps out the wind of the 3rd embodiment.

Among the figure 1, press husky table, 2, the post that keeps out the wind, 3, mortise, 4, the heat radiation awl, 5, the sand dune, 6, table leg, 7, tenon.

In first embodiment shown in Figure 1, after pressing the husky table (1) and the post (2) that keeps out the wind to be transported to the operation place and to be assembled into primary structural component, lining up huge array covers around Gobi desert desert or the sand dune, the front and rear row position is interlaced, leave 10 to 20cm slit around pressing husky table, table also leaves 8 to 16cm space down, constitutes one with pressing husky table after the post that keeps out the wind vertically inserts and rotates 90 ° in the mortise.

In second embodiment shown in Figure 2, press husky table (1) to be rectangle or square, desktop raises up, there is heat radiation awl (4) on the surface, caused the coarse and uneven of the face of land on from the macroscopic view to the microcosmic, having keeps out the wind fixes the sand, the effect that astigmatism is dispelled the heat and prevented to trample, the centre has mortise (3) to be used for installing and the post (2) that fixedly keeps out the wind, dome is upwards caved in in the bottom surface, has retaining and conserveing soil moisture and reduces the effect of materials, and four very short table legs (6) are distributed in four jiaos, table leaves 8 to 16cm space down, help the vegeto-animal procreation of living, the desktop painted white has astigmatism and regulates the effect of temperature.

In the 3rd embodiment shown in Figure 3, the post (2) that keeps out the wind is for cylindrical, highly be respectively 80,100,120 and four kinds of specifications of 140cm respectively account for 25%, the lower end has tenon (7) can vertically insert in the mortise (3), forming height differs, uneven forest shape windbreak, cylinder upper surface are painted red, green, blue, Bai Si kind color, have the toning effect.
