Abstract

The utility model relates to a concrete anti-collision guard bar. The concrete anti-collision guard bar of the utility model comprises a guard bar base and a guard bar wall, which is characterized in that the guard bar wall is poured by the concrete, the facing collision surface of the wall is single slope, and the wall is prefabricated and installed and is provided with holes. The guard bar base is anchoring reinforced bars or anchoring steel piles. The guard bar wall is connected with the base through the guard bar base. The concrete anti-collision guard bar has reasonable and compact structural design, high anti-collision capability and road maintenance cost saving.

Description

A kind of concrete anticollision barrier

Technical field

The utility model relates to highway anti-collision guardrail, especially a kind of novel concrete anticollision barrier.

Background technology

In China, etesian traffic accident is all in rapid increase, and especially highway accident more very.It is one of major reason that takes place highway accident that highway lacks good guardrail facility, especially for those road conditions relatively poor (as camber big and have the mountain road of the gradient) and the bigger oversize vehicle of load-carrying, its anti-collision facility is few, and protection effect produces little effect.So develop a kind of practicality, highway barrier that crashproof ability is strong becomes very urgent thing.

There is numerous highways in China, and a kind of crashproof ability height, structure is attractive in appearance, floor space is little, cost is low, speed of application is fast concrete guardrail are provided, and can satisfy safety, aesthetic property needs, has saved cost again.

The utility model content

The purpose of this utility model provides a kind of novel highway crashproof concrete guardrail, and this concrete guardrail can effectively stop errant vehicle to run off road.

For realizing this purpose, the utility model adopts following technical scheme: the crashproof concrete guardrail of this highway comprises guardrail basis and guardrail body of wall, it is characterized in that prefabricated on the ground installation guardrail body of wall; Prefabricated units are porose concrete slab; Reserved steel bar is left in the precast concrete plank both sides; Precast concrete plank is connected to become whole guardrail body of wall by cast-in-place section; The guardrail body of wall is met the face of hitting for single domatic.The guardrail body of wall is connected with the basis by the guardrail basis; The guardrail basis is an anchor bar, and the guardrail basis also can be the anchoring steel pipe pile.The bottom of anchor bar and anchoring steel pipe pile places in the basis, is connected with the basis.

Press the anticollision barrier that the utility model is implemented, the guardrail body of wall is connected with the basis by the guardrail basis.Among a kind of embodiment, the guardrail basis places the interior anchor bar in basis for the bottom, and the guardrail body of wall is that the bottom places the anchoring steel pipe pile in the basis among the another kind of embodiment, and two kinds of embodiment have strengthened the crashproof ability of guardrail and improved protection effect.

The utility model reasonable in design, simple and direct can reach and prevents that errant vehicle from running off the purpose of guardrail, and cost is low, speed of application fast, good looking appearance, and real be that the remarkable and useful improvement of a kind of effect designs.

Fig. 2 is the facade structures schematic diagram of another kind of embodiment;

Fig. 3 is a sectional view of the present utility model.

The specific embodiment

Now the utility model is described in further detail in conjunction with the accompanying drawings.

In embodiment as shown in Figure 1, form by cast-in-place section 1 and prefabricated section 2 by the body of wall 6 of concreting, prefabricated section is porose 4 concrete slab, and the guardrail body of wall is connected with basis 5 by anchor bar 3, and anchor bar 3 is called the guardrail basis.

In embodiment as shown in Figure 2, form by cast-in-place section 1 and prefabricated section 2 by the body of wall 6 of concreting, prefabricated section is porose 4 concrete slab, and the guardrail body of wall is connected with basis 5 by anchoring steel pipe pile 3, and anchoring steel pipe pile 3 is called the guardrail basis.

The body of wall section wherein, has to be that on one side vertical edges, vertical edges one side are non-ly should hit face as shown in Figure 3 among above-mentioned two kinds of embodiment.Meet the face of hitting and be made up of 1,2 and 3 three face for list is domatic, wherein 1 and 3 is nonessential, and 2 is essential.

The structure of whole guardrail preferably forms in the following manner: at first prefabricated concrete slab with holes, and in the basis, imbed anchor bar or anchoring steel pipe pile then as the guardrail basis, and the guardrail basis firmly is connected with the basis.At last build cast-in-place section, utilize cast-in-place section precast concrete block is connected to become whole guardrail in the position of anchor bar and anchoring steel pipe pile.

Claims

1, a kind of concrete anticollision barrier comprises guardrail basis and guardrail body of wall, it is characterized in that, the guardrail body of wall is made up of prefabricated section and cast-in-place section, and the guardrail body of wall is met the face of hitting for single domatic, and prefabricated section is porose, and the guardrail body of wall is by guardrail basis and basic the connection.

2, concrete anticollision barrier according to claim 1 is characterized in that, the guardrail basis places the interior anchor bar in basis for the bottom.

3, concrete anticollision barrier according to claim 1 is characterized in that, the guardrail basis places the interior anchoring steel pipe pile in basis for the bottom.
