Abstract

The utility model discloses a concrete crashproofing guardrail of a road central separation area, including a guardrail foundation and a guardrail wall body, the guardrail wall body is in a single-sheet concrete structure, namely, the left side and the right side of the guardrail are respectively the collision surfaces of the vehicles on the lanes in two directions, and the collision surfaces have a single slope respectively. The foundation of the guardrail is embedded in the pavement of the road central separation area or is connected to bridge flanges via steel bars. The concrete guardrail can be prefabricated or cast on site. The concrete guardrail structure is narrower in wall body, less in occupied area, convenient in installation, and high in crashproofing capability.

Description

Highway median strip concrete anticollision barrier

Technical field

The utility model relates to a kind of highway concrete guardrail, particularly a kind of median strip concrete anticollision barrier that is applied to high-grade highway.

Background technology

In China, etesian traffic accident is all in rapid increase, and especially highway accident more very.The highway particularly good guardrail facility of high-grade highway shortage is one of major reason that takes place highway accident, and especially for the central strip region, vehicle passes through guardrail easily, invades the subtend track, causes second accident.And for the highway in some special complicated locations, because steric requirements limits to the construction of median barrier and make troubles, so develop a kind of practicality, area occupied is little and crashproof ability is strong median strip concrete guardrail becomes very urgent thing.

There is numerous high-grade highways in China, and the median strip concrete guardrail that a kind of crashproof ability is high, structure is attractive in appearance, floor space is little, cost is low, speed of application is fast is provided, and can satisfy safety, aesthetic property needs, has practiced thrift cost again.

The utility model content

The purpose of the utility model provides a kind of novel crashproof concrete guardrail in highway median strip, and this concrete guardrail can effectively stop errant vehicle to pass through and can normally lead to vehicle.

For realizing this purpose; The utility model adopts following technical scheme: this highway median strip concrete anticollision barrier; Comprise guardrail basis and guardrail body of wall; The revetment body is as a whole with the basis, domatic two faces of hitting of meeting to the track vehicle that are respectively in the wherein said concrete guardrail body of wall left and right sides.

Said meeting hit face bottom and be that the straightway on vertical road surface, top are singly domatic, and the domatic gradient is 9 °～11 ° '.

Said guardrail basis embeds road surface, highway median strip or is connected with bridge flange plate through reinforcing bar.

Said guardrail foundation bottom is provided with the concrete bolster or is directly embedded into below the road surface.

Guardrail top width and bottom width can be adjusted according to actual needs; Guardrail body of wall toe can be right angle or acute angle; The guardrail body of wall is connected with the basis through the build-in connection or directly is mounted in below the road surface.

The utility model reasonable in design, simple and direct can reach the purpose that prevents that errant vehicle from passing through guardrail and vehicle is normally led, and cost is low, speed of application is fast, good looking appearance, can install and use in narrower central strip region.Real is the remarkable and useful improvement design of a kind of effect.

The specific embodiment

Combine accompanying drawing that the utility model is further described at present.

As shown in Figure 1, this is the domatic median strip of an a kind of list concrete guardrail.Mainly form by protecting wall 1.

In Fig. 1, the embodiment shown in 2, by the body of wall 1 of concreting, the face of hitting of meeting that is guardrail of body of wall wherein; Two side slopes all are single domatic 2 and 3; Slope angle is an acute angle, and top, slope and sloping bottom width degree can be adjusted according to actual conditions, and the domatic gradient can be 9 degree-11 degree.

As shown in Figure 3, the guardrail body of wall is connected to build-in with the basis and is connected, and the bottom of guardrail body of wall is provided with guardrail basis 4, and this basis 4 is arranged in the concrete water shutoff layer 5 of highway median strip, but also can bolster 6 be set at the basis of guardrail body of wall 14 downsides.

As shown in Figure 4, the guardrail basis also can directly be mounted in below the road surface.

Claims

1. highway median strip concrete anticollision barrier; Comprise guardrail body of wall and guardrail basis; It is characterized in that: domatic two faces of hitting of meeting to the track vehicle that are respectively in the said concrete guardrail body of wall left and right sides, guardrail basis embed road surface, highway median strip or are connected with bridge flange plate through reinforcing bar.

2. highway as claimed in claim 1 median strip concrete anticollision barrier is characterized in that: said meeting hit the straightway that there is vertical road surface in the face bottom, and top is single domatic.
