Abstract
The utility model relates to a flexible dust-suppression net wind-shield wall, which comprises dust suppression nets, a steel frame and a concrete substrate, wherein the steel frame is fixed on the concrete substrate, the steel frame consists of steel frame stable supports, a stable horizontal support frame and a horizontal rigid connection piece, top ends of every two adjacent steel frame stable supports are connected with each other through the horizontal rigid connection piece, the lower parts of every two adjacent steel frame stable supports are connected with each other through the stable horizontal support frame, the horizontal rigid connection piece is provided with a hook, the top end of the dust suppression net is hung on the hook, the bottom part of the dust suppression net is fixed by wire cable roll hem, the middle part of the dust suppression net is fixed on the steel frame through a steel cable, the quantity of the dust suppression nets is two, and the two dust suppression nets are arranged on the front surface of the steel frame. The flexible dust-suppression net wind-shield wall can absorb partial wind energy and wind pressure, and a majority of the wind load on the net body is directly transferred onto the steel structure and the foundation, so that better impact resistance can be realized. The wind speed can be reduced by more than 80 to 90 percent, and the concentration distribution of the flying dust can be reduced by 85 to 98 percent.
Description
Technical field
The utility model relates to a kind of flexible dust-suppression net windbreak.
Background technology
The industry of air storage, raw material and the solid waste that contains particle for building, its wind primary decisive factor that causes moving is a wind speed.Less solid particle mainly contains three kinds of motion states under wind action: the maximum down moving particles of certain wind speed (diameter>1000 micron) becomes spiral shell along ground surface and moves; Fine particle (diameter < 100 microns) is then carried with the wind by turbulent flow, and motion is called suspension; Diameter leapt in the atmosphere between the particle (100 microns-1000 microns) of centre before this, then fell ground after rise along regular track again and was referred to as to quiver.The suspension of particle is the main forms of motion of wind erosion phenomenon with quivering; And what atmospheric environment was worked the mischief mainly is suspended particulate, and particularly to be suspended in atmosphere be that harmfulness is arranged most to the particle below 10 microns and 10 microns, and in a single day this part particle is suspended in the air; Because velocity perturbation in vertical direction; Be difficult to fall back to ground again, but other local diffusions of box haul, and then cause serious air pollution and other environmental problems; Also caused simultaneously the loss of raw material, the storing cost is improved.But also there is not very good solution at present.
The utility model content
The technical problem that the utility model will solve provides a kind of flexible dust-suppression net windbreak, and this windbreak has the effect that reduces wind speed, control airborne dust.
In order to solve the problem that prior art exists, the technical scheme that the utility model adopts is:
Flexible dust-suppression net windbreak includes dust-suppression net, steelframe and concrete pedestal, and described steelframe is fixed on the concrete pedestal; Steelframe is made up of steelframe stable support, maintenance level bracing frame and horizontal rigidity connector, and the top of adjacent two steelframe stable support connects through horizontal rigidity connector, and the bottom of adjacent two steelframe stable support links to each other through the maintenance level bracing frame; Horizontal rigidity connector is provided with hook; The top of dust-suppression net hangs on the hook, and the bottom of dust-suppression net is fixed through the wire rope crimping, and the mid portion of dust-suppression net is fixed on the steelframe through cable wire; The quantity of dust-suppression net is two, is arranged on the front of steelframe.
The mesh of described dust-suppression net is a rhombus, screen frequency be 1260 holes/square metre.
Advantage and effect that the utility model had are:
The flexible dust-suppression net windbreak of the utility model is owing to have following structure: steelframe is fixed on the concrete pedestal; The top of adjacent two steelframe stable support connects through horizontal rigidity connector; The bottom of adjacent two steelframe stable support links to each other through the maintenance level bracing frame, and the top of dust-suppression net hangs on the hook, and the bottom of dust-suppression net is fixed through the wire rope crimping; The mid portion of dust-suppression net is fixed on the steelframe through cable wire; Therefore but absorption portion wind energy, blast, the major part with the suffered wind load of dictyosome is directly delivered on steel work and the basis simultaneously, and is more shock-resistant.Because the mesh of dust-suppression net is a rhombus, screen frequency be 1260 holes/square metre, percent opening is that 40% o'clock quick-acting fruit of checking is best; Reduce more than the wind speed 80-90%, the airborne dust CONCENTRATION DISTRIBUTION reduces 85-98%, and double-layer drilling is the kinetic energy that 40% flexible wind-proof dust-suppression net can more effectively reduce wind; Reduce the leeway of stockpile both sides, pusher field, the possibility that reduction produces eddy current wind; Stack simultaneously the area size of stockpile according to rickyard, double-layer drilling is that effective protection horizontal range of 40% flexible wind-proof dust-suppression net is 30 times of height, and net height should be controlled at the 1-1.3 scope doubly of dump height; When air communication is crossed dictyosome; Air force reduces, and net is inboard through air-flow wind, the inboard calm effect of the little wind in the outside a little less than forming disturbing flow on the dictyosome to reach high wind inboard, the outside, prevents dust from flying.Lose the kinetic energy of incoming flow wind to greatest extent, avoid incoming flow wind to form eddy current, reduced the dirt purpose thereby reach.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model.
Dust-suppression net 1, steelframe 2, concrete pedestal 3, steelframe stable support 21, maintenance level bracing frame 22, horizontal rigidity connector 23, cable wire 5.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to detail:
As shown in Figure 1, the flexible dust-suppression net windbreak of the utility model includes dust-suppression net 1, steelframe 2 and concrete pedestal 3, and described dust-suppression net 1 is polyethylene silk spinning knitmesh, and the ultimate strength of screen cloth is 400N.Described steelframe 2 is fixed on the concrete pedestal 3; Steelframe 2 is made up of steelframe stable support 21, maintenance level bracing frame 22 and horizontal rigidity connector 23; The top of adjacent two steelframe stable support 21 connects through horizontal rigidity connector 23; 1/3 place, bottom of adjacent two steelframe stable support 21 links to each other through maintenance level bracing frame 22, and horizontal rigidity connector 23 is provided with several anticorrosion, antirust hooks.The top of dust-suppression net 1 hangs on the hook, and the bottom of dust-suppression net 1 is fixed through the wire rope crimping, and the both sides of dust-suppression net 1 are fixed on the steelframe 2 with U type card and cable wire 5, and laterally clamp for per 1-1.2 meters with cable wire the dictyosome inside and outside, uses the about cable wire of 2.5MM copper cash colligation at last.The quantity of dust-suppression net 1 is two, two nets smooth, vertical, tight front that is installed in steelframe 2 that is superimposed.The mesh of dust-suppression net 1 is a rhombus, long limit 10mm minor face 7mm.Screen frequency be 1260 holes/square metre, percent opening is 40%.2.6 meters of monolithic dust-suppression net fabric widths, length customize 3 meters to 50 meters as required.Cross the nettle connection to monolithic Netcom and become wide 50 meters high 50 meters dictyosomes.
