Abstract
The utility model discloses an anti-collision guardrail comprising a guardrail wall body made of concrete, and an expansion type foundation. The guardrail wall body is fixed on the expansion type foundation, and the front end of the expansion type foundation extends out of the guardrail wall body. The anti-collision guardrail has the advantages of collision prevention, strong guiding property, capability of preventing the side turning or climbing of various vehicles, and high safety factor.
Description
Technical field
The utility model relates to the road and bridge anti-collision facility, relates in particular to anticollision barrier.
Background technology
At present; the anticollision barrier that is used for road and bridge has a variety of, and the existing speedway bridge crossing bridge pier protection semi-rigidity rails that adopt in the continuous increase along with the speedway mileage more; the ratio of the shared mileage of bridge crossing is increasing, and bridge crossing bridge pier bump accident is more and more.The bridge crossing traffic accident has its exclusive feature, from present bridge crossing traffic accident analysis, when accident vehicle was compact car, semi-rigidity rail can play the better protect effect, small-sized accident vehicle can not leap and pass through guardrail, and is limited to the harm of bridge crossing bridge pier; But for medium-sized, large-scale and outsized vehicle, the obvious scarce capacity of semi-rigidity rail, such accident vehicle is easy to pass through guardrail and direct head-on crash takes place the bridge crossing bridge pier, under the king-sized situation of accident vehicle tonnage, directly sever bridge pier, have a strong impact on traffic, the economic loss heaviness.As seen, do not having under the situation of reliable anti-collision facility, be difficult to guarantee the safety of road and bridge.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of crashworthiness and guidance quality strong, can stop the various types of vehicles rollover or cross, anticollision barrier that safety factor is high.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of anticollision barrier comprises the guardrail body of wall and the spread foundation of being made by concrete, and described guardrail body of wall is fixed on the spread foundation, and the front end of described spread foundation stretches out the guardrail body of wall.
Described guardrail body of wall front end is provided with the middle part and climbs the face of hitting of meeting to the anti-rollover resistance of lower recess.
The resistance of described anti-rollover is climbed and is met the face top of hitting and be provided with retaining bank to front protrusion, meets to hit the face middle part and be provided with plane perpendicular to the top, spread foundation, and the bottom is provided with a plurality of inclined-planes that turn forward.
Described retaining bank is provided with along the roadbed direction continuously in guardrail body of wall top.
Be equipped with arrangement of reinforcement in described guardrail body of wall and the spread foundation.
The back transverse plane of described guardrail body of wall is not concordant with the rear end face of spread foundation.
Compared with prior art, advantage of the present utility model is:
Anticollision barrier of the present utility model; combination by guardrail body of wall and spread foundation; the crashworthiness and the steering capability of anticollision barrier have been improved greatly; can effectively stop all types of accident vehicles to break through or turn on one's side, cross out guardrail; satisfy the requirement of safety evaluation standard; can reduce accident vehicle to the harm of road and bridge, the safety of protection exception vehicle reduces life and property loss.At guardrail body of wall front end meet the hit face of middle part to lower recess is set, can plays vehicle rollover, the effect that stops vehicle to ascend anticollision barrier of preventing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Each label is represented among the figure:
1, guardrail body of wall; 2, spread foundation; 3, meet the face of hitting; 4, back transverse plane; 5, arrangement of reinforcement; 6, basic retaining wall; 31, retaining bank; 32, plane; 33, inclined-plane.
The specific embodiment
Fig. 1 shows a kind of anticollision barrier embodiment of the present utility model; this anticollision barrier comprises the guardrail body of wall 1 and the spread foundation 2 of being made by concrete; spread foundation 2 is the shape of falling L; and be seated on the basic retaining wall 6; guardrail body of wall 1 is fixed on the spread foundation 2; the front end of spread foundation 2 stretches out guardrail body of wall 1; combination by guardrail body of wall 1 and spread foundation 2; the crashworthiness and the steering capability of anticollision barrier have been improved greatly; can effectively stop all types of accident vehicles to break through or turn on one's side; cross out guardrail; satisfy the requirement of safety evaluation standard; can reduce the harm of accident vehicle to road and bridge; the safety of protection exception vehicle reduces life and property loss.
In the present embodiment, guardrail body of wall 1 front end is provided with the middle part and climbs the face of hitting 3 of meeting to the anti-rollover resistance of lower recess, can play vehicle rollover, the effect that stops vehicle to ascend anticollision barrier of preventing.Anti-rollover resistance is climbed and is met the face of hitting 3 tops and be provided with retaining bank 31 to front protrusion, meet the face of hitting 3 middle parts and be provided with plane 32 perpendicular to 2 tops, spread foundation, the bottom is provided with a plurality of inclined-planes that turn forward 33, retaining bank 31 is provided with along the roadbed direction continuously in guardrail body of wall 1 top, this retaining bank 31 can stop the vehicle anticollision barrier of ascending, inclined-plane 33 can transfer the kinetic energy of vehicle to potential energy, helps to reduce to impact.Be equipped with arrangement of reinforcement 5 in guardrail body of wall 1 and the spread foundation 2, the back transverse plane 4 of guardrail body of wall 1 is not concordant with the rear end face of spread foundation 2, can improve the bulk strength of anticollision barrier.
Above-mentioned is preferred embodiment of the present utility model, is not the utility model is done any pro forma restriction.Though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model.Any those of ordinary skill in the art, under the situation that does not break away from the technical solutions of the utility model scope, all can utilize the technology contents of above-mentioned announcement that technical solutions of the utility model are made many possible changes and modification, or be revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not break away from technical solutions of the utility model, all should drop in the scope of technical solutions of the utility model protection any simple modification, equivalent variations and modification that above embodiment did according to the utility model technical spirit.
