Abstract
The utility model relates to a central separation band separation type concrete guard fence for high-grade highways. The utility model is composed of a left and a right concrete guard fences and a concrete water sealing layer, wherein, the concrete water sealing layer is positioned on both sides of the left and the right concrete guard fences, and an intersection angle between the cross section of one side facing a roadway of the left and the right concrete guard fences and the bottom surface is single in slope. The utility model can not only effectively prevent a vehicle to which an accident occurs from being overturned but also can reduce human body casualties.
Description
The utility model belongs to highway safety facility field, particularly the guardrail field on the high-grade highway median strip.
Disclosed a kind of median strip separate type concrete guardrail among the JTJ074-94 " expressway traffic safety facilities design and construction technical specification ", because its section is many slopes and curved surface shaped, and highly have only 81 centimetres, incompatible speedway based on Medium Truck, the effect of blocking to this type of highway wagon flow is poor, overturn accident is many, and loss is serious.
Goal of the invention of the present utility model is to provide a kind of section reasonable, does not firmly sink, and blocking of vehicle made good use of, and overturn accident is few, and reduces the high-grade highway median strip separate type concrete guardrail of highway investment.
The utility model is realized goal of the invention by following measure:
1. to meet the hypotenuse of roadway one side section be single slope to concrete guardrail, and the back side is upright, reasonable to guarantee the guardrail section configuration;
2. 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 left and right sides concrete guardrail and concrete water shutoff layer, the concrete water shutoff is placed on the both sides of left and right sides concrete guardrail, left and right sides concrete guardrail and concrete water shutoff are placed on above the roadbed, the hypotenuse that left and right sides concrete guardrail is met roadway one side section is single slope, and the back side is upright.Banket between the concrete guardrail of the left and right sides.Said single slope refers to that promptly the section of a side concrete guardrail is that a right angle is trapezoidal, and concrete guardrail is met the side of car direction and the angle of bottom surface is unique, and the tangent value of this angle is unique.Concrete guardrail inside, the left and right sides is positioned on the concrete water shutoff layer and is provided with drain hole; The left and right sides former concrete guardrail of concrete guardrail aspect ratio is high 10～30 centimetres.
Description of drawings:
Fig. 1: structure diagram of the present utility model
Below in conjunction with drawings and Examples in detail detailed construction of the present utility model is described in detail.
A kind of high-grade highway median strip separate type concrete guardrail, as shown in Figure 1, it is made up of left concrete guardrail 1, right concrete guardrail 2 and concrete water shutoff layer 3,4, and concrete water shutoff layer 3,4 places the both sides of left concrete guardrail 1 and right concrete guardrail 2 respectively.A left side concrete guardrail 1 and right concrete guardrail 2 are positioned on the roadbed 6, between banket 7, it meets a side section of roadway and the angle of bottom surface is unique, and the tangent value of this angle is unique, inside is positioned at concrete water shutoff layer 3,4 and is provided with drain hole 5, the former concrete guardrail of their aspect ratio is high 20 centimetres, or 30 centimetres, or 10 centimetres.
Invention of the present utility model can block effectively not only that accident vehicle does not overturn or few the overturning, reduces personal injury, and can reduce construction costs.
