Abstract
The utility model relates to a concrete guard fence for a central separation zone on a high-grade highway, which is composed of a concrete guard fence and a pillow block, wherein, the pillow block is arranged on the lower side of a seal layer, the concrete guard fence is arranged on the upper side of the pillow block, and the both sides of a cross section of the concrete guard fence are provided with a single slope rate. The utility model not only can effectively prevent accident vehicles from rolling over or rarely rolling over and reduce human body casualties but also can save engineering cost by 1-3%, and the investment of the utility model is saved by 3-10% compared with a steel guard fence.
Description
The utility model belongs to highway safety facility field, particularly the guardrail field on the high-grade highway median strip.
Present used high-grade highway median strip concrete guardrail is formed because its section is many slopes and curved surface, and insufficient height, and incompatible wagon flow based on Medium Truck is formed, so poor to the effect of blocking of this wagon flow composition, overturn accident is many, and loss is big.
Goal of the invention of the present utility model is the weak point that overcomes above-mentioned prior art, provides a kind of section reasonable, does not firmly sink, and blocking of vehicle made good use of, and overturn accident is few, and saves the high-grade highway median strip concrete guardrail of construction investment.
The utility model is realized goal of the invention by following measure: 1. the both sides of concrete guardrail section are single slope, and are reasonable to guarantee section configuration; 2. the concrete guardrail basis is a bolster, to guarantee that guardrail is firm, prevents its sinking; 3. the former guardrail of the aspect ratio of concrete guardrail is high 10～30 centimetres, overturns to reduce.
Structure of the present utility model is made up of concrete guardrail and bolster, bolster place seal below, concrete guardrail place bolster above, the both sides of concrete guardrail section are single slope.Said single slope refers to that promptly the section of concrete guardrail is an isosceles trapezoid, and two trapezoidal waists of these isosceles are straight line, and the side of concrete guardrail and the angle of bottom surface are unique, and the tangent value of this angle is unique.The bottom of concrete guardrail is provided with the cavity, and concrete guardrail inside is positioned at and is provided with drain hole on the seal, and the former concrete guardrail of its aspect ratio is high 10～30 centimetres.
Description of drawings:
Fig. 1: structure chart of the present utility model
Fig. 2: the utility model vertical view
Below in conjunction with figure and embodiment in detail detailed construction of the present utility model is described in detail.
A kind of high-grade highway median strip concrete guardrail, as shown in Figure 1, it is made up of concrete guardrail 1 and bolster 6, bolster 6 place seal 4 below.Concrete guardrail 1 place bolster 6 above, the both sides of its section are single slope, the bottom is provided with cavity 2, inside is positioned at and is provided with drain hole 3 on the seal 4, the former concrete guardrail of its aspect ratio is high 20 centimetres, or 30 centimetres, or 10 centimetres.
Be provided with expansion joint (E.J.) 7 as shown in Figure 2 between the concrete guardrail.
Use the utility model can block effectively not only that accident vehicle does not overturn or few the overturning, reduce personal injury, and can save construction costs 1～3%, reduce investment outlay 3～10% than steel guard rail.
