Abstract

The utility model discloses a plastic net used for preventing the sand and snow from piling on the highways, relating to a traffic protection facility, aiming at eliminating the impact of wind blowing and sand or snow piling on the highway surface so that the situation of difficult traffic and frequent accident is avoided. The utility model is characterized in that: the utility model consists of two parts, namely, an upright bracket and a plastic net, wherein, the upright bracket is formed by the linear array of a plurality of upright poles with an equal distance between every two poles and a certain distance away from the windward side; the plastic net consists of a plurality of HDPE high-density polyethylene plastic net sheets which are formed through the combination of a plurality of parallel plastic belts and cross plastic belts, with a plurality of net holes formed and taking the shape of a triangle with a certain oblique angle; all the net sheets are fixed onto the upright bracket through a plurality of metal wires. The utility model is mainly arranged on the windward side of the road, which can well conduct the wind speed reduction and wind direction change when the wind is blowing, so that the sand and snow piling on the road surface is effectively prevented, and not only the smooth running of the vehicles is guaranteed, but also the accidents are reduced.

Description

The long-pending plastic wire of the husky snow drift of prevention high-grade highway

Technical field

The utility model relates to the traffic protective equipment, particularly relates to a kind of protective equipment that prevents high-grade highway wind sand, the long-pending road surface of snow drift.

Background technology

Long-pending sand in the road surface of high-grade highway and accumulated snow are key factors that influences vehicle smooth and cause traffic accident, the normal at present prevention wind sand that adopts, the major measure that snow gathers is masonry marshalling engineering construction thing and plant protection forest belt, dull stiff the having high input of masonry marshalling engineering construction thing, do not meet economic and practical, harmonious and the ecological friendly highway construction theory of environmental protection, though and the plant prevention forest belt is good, but because of taking effect slowly, be subjected to seasonal effect big higher with the construction maintenance cost, especially concerning the winter of northern area, then short-term effect is poor, normal influential unimpeded and accidents caused generation; In addition, through inquiring about, do not find the wind snow and the long-pending effective means of sand drift that can prevent the road surface again as yet.

The utility model content

The utility model proposes with regard to being based on this circumstances, a kind of high-grade highway prevention wind snow and the long-pending plastic wire of sand drift have been designed, its purpose just is to guarantee that the road surface is unimpeded and makes every effort to reduce the generation of traffic accident, the sand prevention snow defence measure ratio of described measure and present routine, the characteristics that have the harmonious instant effect of environmental protection again and can economize on resources.

Agent structure of the present utility model includes two parts: column support and plastic wire.

Described column support is the support of fixed plastics net, is arranged by many root post one lines to form, single post can adopt concrete precast element, timber or steel, according to identical distance, bury the weather side a distance that stands in highway, to terminal column fixed support in addition.

Described plastic wire, be to block to change the work plane of wind direction, form by some HDPE high-density polyethylene plastics net sheets, have low temperature resistant embrittlement, high temperature resistant aging characteristics, the net sheet is constituted by the plastic tape of some parallel plastic tapes and intersection, what its intersection effect was best is " people " font combination that can be formed with a fixed inclination between parallel plastic tape, constitutes leg-of-mutton oblique mesh, and whole net sheet is fixed on the column support by wire.

The utility model generally is installed in the other windward area of highway, can play the effect that reduces wind speed and change wind direction preferably when meeting strong wind and blowing, and then can effectively prevent the husky snow drift on road surface long-pending, and it is unimpeded both can to have guaranteed to drive a vehicle, and can the minimizing accident take place again.The utility model sees it is a kind ofly can effectively prevent and treat the long-pending measure of high-grade highway wind snow and sand drift at present.

Description of drawings

Fig. 1 schematic diagram of installing and using of the present utility model;

The mesh-structured schematic diagram of Fig. 2 the utility model plastic deeping;

Fig. 3 plastic wire schematic top plan view;

Fig. 4 the utility model general assembly schematic diagram.

Among the figure, 1 is column support, and 2 is plastic deeping, and 3 are fixedly backguy, and 3 ' for supporting batter post, and 4 is highway, and (1) is the plastic wire cross band, and (2) are the vertical band of plastic wire, and (3) are for being with the angle of cut in length and breadth.

The specific embodiment

The utility model is a kind of control high-grade highway, moves in big wind and forms the long-pending facility of the husky snow drift in road surface down, is illustrated in conjunction with the accompanying drawings with regard to the specific embodiment below.

1, determining of pre-sand prevention, the long-pending plastic wire installation site of snow drift:

Generally be the weather side that is installed in sand damage, snow injury highway section, vertical with prevailing wind usually, angular deviation is no more than 25 °, and the distance from the highway limit is 25～35 times of plastic wire height.。

2, column support is fixing:

The column height is generally about 2m, when selecting circular for use, diameter is 0.12m, when selecting square column for use, the length of side is buried underground according to 3m～5m spacing in 0.1m～0.15m scope, about ground level 1.5m, terminal column will suitably be supported, so that stablize stand, its way is: adopt the low anchor formula backguy of " people " font or the form of oblique column.

3, the installation of plastic deeping 2:

The high about 1.2m of plastic deeping, with wire from the top of column down, uniformly-spaced bundle, height off the ground is in 0.15m～0.3m scope, be that the prevention wire decreases drawing of plastic deeping, generally will with some soft dysgeogenous materials of contact surface place pad of plastic wire.

Embodiment: as Fig. 1～shown in Figure 4, column support 1 is a circular columns, and diameter selects 0.12m, and height is 2m, spacing with 4m, one line is arranged in apart from highway 4 and is the weather side of 40m, and an end selects for use fixedly backguy 3 fixing, and the other end adopts support batter post 3 ' fixing, plastic sheet 2 usefulness wires equally spaced are bundled on the column 1, height off the ground is 0.3m, and plastic sheet wherein is crisscross, and vertical sheet (2) is with herringbone mode and the combined triangularity grid that makes it of transverse sheet (1).

Claims

1. the long-pending plastic wire of the husky snow drift of prevention high-grade highway is characterized in that: be made of column support wherein column support and plastic wire two parts, form by many root post one lines arrangements, according to identical distance, bury the weather side a distance that stands in highway, to terminal column fixed support in addition; Plastic wire wherein is made up of some HDPE high-density polyethylene plastics net sheets, and the net sheet is combined by the some parallel plastic tapes and the plastic tape of intersection, and whole net sheet is fixed on the column support by wire.

2. the long-pending plastic wire of the husky snow drift of prevention high-grade highway according to claim 1 is characterized in that: between the plastic tape of intersection and the parallel plastic tape is that " people " font makes up, and the mesh of formation is the oblique mesh of triangle with a fixed inclination.
