Abstract
The utility model relates to a highway guard-rail, which is a highway guard-rail with L-shaped structure suitable for the reconstruction of old highways. The utility model comprises a guard-rail base (12), a guard-rail wall (11) which is connected with the guard-rail base (12) through steel bars, and also comprises a plurality of connecting steel bars (14). The connecting steel bars (14) are poured in the interior of the guard-rail base (12), penetrating through the surface of one side of the guard-rail base (12) adjacent to the pavement (13) and extending into the interior of the pavement (13), and thus the guard-rail base and the pavement are connected together. The L-shaped concrete guard-rail has the advantages that the stressed steel bars in the guard-rail base extend to the pavement and form an L-shaped integral structure with the guard-rail wall, making use of the structure of the pavement to obtain the stability of the guard-rail base.
Description
Technical field
The utility model relates to a kind of highway barrier, and particularly a kind of road structure that is suitable for is the highway barrier rigid pavement, mountain highway cliff cliff highway section.
Background technology
In China, year traffic death by accident people ordered series of numbers the first in the world.Along with the increase of road, vehicle, population, China's traffic accident quantity and death toll are also increasing, and particularly in recent years, road accident rate and causality loss were sharply risen, and wherein mountain highway vehicle bob precipice causality loss accounts for suitable proportion.The reason that vehicle bob precipice accident takes place is many-sided, as hypervelocity overload, fatigue driving, mechanical breakdown or the like, is one of them major reason but road lacks necessary traffic safety protective equipment or protective equipment scarce capacity.Along with China's development of the West Regions implementation, western road haulage development is accelerated, and highway construction begins to extend to mountain ridge hilling terrain.And guardrail can effectively stop vehicle to go out highway as most important safety device on the highway, reduces causality loss, thereby comes into one's own day by day.
At present, China's mountain area ordinary highway is not provided with guardrail substantially, and most of highway section is without any fender, and in a single day vehicle takes place out of control, is easy to go out road, causes car crash.The highway section that has utilizes the trackside landscape tree to protect, and its protective capacities is limited, and bigger for occupant's impact acceleration.The bend place of some highway is provided with crash bearer, crashproof wall, but these facilities all are footless masonries, and its protective capacities is relatively poor, is difficult to stop oversize vehicle.
Have many at present about designing and developing the technology of highway barrier, for example existing a kind of chair type highway barrier (referring to accompanying drawing 1) that is used for the precipitous highway section of mountain highway.It comprises that retaining bank 5 is climbed in guardrail body of wall 1, guardrail basis 2, guardrail leg 3, arrangement of reinforcement 4, resistance and the guardrail body of wall is met the face of hitting 7, wherein guardrail body of wall 1 is cemented on the guardrail basis 2, the guardrail basis has down L shaped guardrail leg 3, be the seat form, be located on the subgrade retaining wall 6, guardrail leg 3 is in the side that the guardrail body of wall is met the face of hitting 7, pastes mutually with subgrade retaining wall 6 inboards.By this structure, basic shank is embedded sub-surface, utilize sub-surface the drag of basic shank to be strengthened the stability of guardrail.This structure can adapt to well and has the highway section that the retaining wall width is narrower and top width is consistent, or earth roadbed highway section, but for the highway section that retaining wall width differs, width is bigger, or the highway section of adopting non-gravity formula retaining wall, its structure can not be suitable for.Thereby need a kind of guardrail that can be applicable to that old road is transformed, particularly can utilize road structure to solve the guardrail of guardrail stability of foundation.
Summary of the invention
The technical problems to be solved in the utility model is the shortcomings and deficiencies that exist in the above-mentioned existing highway guardrail technology in order to overcome, at the old road transformation of China's mountain area existing highway and research and design goes out a kind ofly can effectively stop errant vehicle to run off road, satisfy " L type " highway barrier of safety evaluation standard-required.
The technical solution of the utility model is to adopt a kind of concrete highway barrier of L shaped structure, comprise the guardrail basis, the guardrail body of wall is cemented on the guardrail basis, it is characterized in that, also comprise a plurality of connecting reinforcements, described a plurality of connecting reinforcement is cast in the inside on guardrail basis, and pass the surface of close road surface one side on guardrail basis, extend to the inside on road surface, both are tightly linked together, guardrail is met the face that hits and is adopted single domaticly, and the angle of cut that guardrail is met the face of hitting and vertical plane is 11 degree, can be provided with a resistance of outwards giving prominence at the top that guardrail is met the face of hitting and climb the retaining bank.
The utility model beneficial effect compared with prior art is, it is by the guardrail form of a kind of " L type ", promptly by being connected the guardrail basis as a whole with road structure, improve the stability of guardrail, make guardrail when being subjected to the errant vehicle bump, road structure is can fellowship stressed, thereby reaches the purpose that the protection errant vehicle runs off guardrail, for the mountain highway improvement project provides a kind of feasible guardrail form.Be characterized in the steel bar stress in the guardrail basis is extended in the road surface, form L shaped overall structure, utilize road structure to solve the stability on guardrail basis with the barrier wall body.
Description of drawings
Fig. 1 is the structural representation of the embodiment of background technology;
Fig. 2 is the structural representation of embodiment of the present utility model.
The specific embodiment
As shown in Figure 2, the utility model adopts the integrally-built concrete guardrail of a kind of L type, wherein guardrail body of wall 11 is cemented on the guardrail basis 12, paste mutually with the outside on road surface 13 inboard on guardrail basis 12, a plurality of connecting reinforcements 14 are cast in the inside on guardrail basis 12, and pass the surface of close road surface 13 1 sides on guardrail basis 12, and extend to the inside on road surface 13, both are tightly linked together.Other structure of guardrail can be same as the prior art, as the guardrail body of wall meet the face of hitting 15 can adopt single domatic, with vertical plane at an angle, for example 11 degree can be provided with an outwards outstanding resistance at its top and climb retaining bank 16.The guardrail top is approximately 1000 millimeters far from the height on road surface, and the guardrail top width is approximately 170 millimeters, low roomyly is about 388 millimeters.Adopt and the same arrangement of reinforcement of guardrail body of wall on guardrail basis 12, and its main muscle diameter is 12 millimeters.
Top embodiment just makes for the ease of understanding, should not be considered to limitation of the invention, and the present invention also can adopt other form to realize.For example the guardrail body of wall can not be provided with resistance and climb the retaining bank, and each size of guardrail body of wall and the size of arrangement of reinforcement all can change, and connecting reinforcement can be changed according to actual conditions with the quantity and the density of vertical direction in the horizontal direction.In addition, the diameter of connecting reinforcement and the length of going deep in guardrail basis and the road surface also can change, as long as its intensity enough.
