Abstract
The utility model provides an anti-collision bridge guardrail capable of preventing a container from overturning. The anti-collision bridge guardrail capable of preventing the container from overturning comprises a substrate, a foundation which is arranged on the lower bottom face of the substrate and a guardrail which is fixedly connected with the substrate, the guardrail comprises a support which is in a strip shape in a longitudinal direction, a plurality of uprights are vertically arranged on the strip-shaped support, at least one horizontal beam is arranged on the uprights, and one side of each horizontal beam is connected with the uprights. Due to the fact that the height of the uprights is increased to enable the horizontal beams to prevent oversize vehicles from overturning out of a road, at the same time when high speed small vehicles come, the substrate can prevent the small vehicles from penetrating through below the horizontal beams, and impact force brought by vehicle collision is reduced by inclined surface of the substrate and a rubber strip which is arranged at one side of each horizontal beam when the guardrail is crushed by the vehicles. The anti-collision bridge guardrail capable of preventing the container from overturning has the advantages of being low in cost, easy to popularize and apply and particularly suitable for various dangerous roads such as bridges and mountain paths.
Description
Technical field
The utility model relates to Bridge guardrail, is specifically related to a kind of container that prevents and turns over Collison fence for bridge and the structure thereof that falls.
Background technology
Existing anticollision barrier generally adopts the regulation of " highway traffic safety facilities design detailed rules and regulations " (JTG/T D81-2006), rail height is generally about 80cm～10cm, be divided into B, A, SB, SA, five grades of SS, the anti-collision automobile quality that highest ranking SS determines is that 18t, speed are 80km/h.
Continuous increase along with the speedway mileage, communications and transportation also grows up thereupon, the bridge pier bump accident that highway bridge occurs is also progressively increasing, from present bridge pier bump accident, find, a lot of accidents the distortion that the bridge pier guardrail hit fully occurs or sever even have container to rout up the inferior accident of bridge, and these Frequent Accidents are born in the bend place of road.The accident origin cause of formation mainly is the guardrail strength deficiency.
At present, retrieve application number and be 200420004329.7 L-type concrete guardrail, it is the guardrail form with a kind of " L-type " in this utility model, by being connected the guardrail basis as a whole with road structure, improve the stability of guardrail, so that guardrail is when being subject to being sky vehicle bump, the structure on road surface can participate in stressed jointly, thereby reach the purpose that the protection errant vehicle runs off guardrail, if but in the face of the fast container car of the speed of a motor vehicle, because the quality of carrying on the container is large, container car and rail collision angle are large, and the problem such as guardrail height is lower, obviously this type of concrete guardrail can not stop that higher vehicle routs up road behind bump.
On the whole, original road guard can not stop container car behind the bump guardrail, routs up outside the road guard.Yet for small-sized vehicle, do not have the height of common guardrail of concrete bed higher, to such an extent as to sometimes clash into guardrail at dilly when the speed of a motor vehicle is too fast, the inertia of impact can cause dilly to be scurried out from guardrail bottom.
The utility model content
