Abstract
The utility model discloses a collision-prevention device for a middle pier of a highway overpass bridge. The collision-prevention device comprises collision-prevention frameworks which are arranged at the two sides of the middle pier along the direction of a highway; each collision-prevention framework comprises four main posts arranged in a 2*2 matrix manner, the main posts are vertically arranged, the lower ends of the main posts are embedded in a foundation, and connecting rods are fixedly arranged between the main posts being adjacent along the periphery direction; the vehicle collision is prevented from damaging the middle pier of the feed overpass bridge by arranging the collision-prevention frameworks, thereby the occurrence of secondary accidents is avoided; simultaneously, the collision energy can be effectively reduced, deformed guardrails can timely recover, the residual deformation is small, and the damage on vehicles and guardrail facilities is smaller; and when the vehicles with the larger tonnage collide with the middle pier, the plastic deformation of a steel framework and the self weight of concrete can be used for stopping the vehicles so as to prevent the damage on the middle pier of the highway overpass bridge.
Description
Technical field
The utility model relates to the traffic safety field, particularly a kind of crashproof well word steel framework device of highway bridge crossing pier that is used for.
Background technology
At present domesticly only can consider that in design highway bridge crossing (for example pedestrian overcrossing) the bump ability to bear of bridge pier can not will consider the central partition anticollision barrier is installed at most in limit of consideration from the main function of use of object.But a large amount of traffic accidents show that the bump that rigidity that central partition anticollision barrier shortage is enough and intensity are resisted truck and passenger vehicle is easy to strike bridge pier, do not have the effect of interception car bump bridge pier preferably at all.Therefore, demand urgently developing and be fit in the highway bridge crossing pier anticollision device, collision-prevention device and come effectively to avoid that pier is collapsed by bump in the highway bridge crossing, and then avoid heavy casualties and enormous economic loss.
The utility model content
In view of this; The purpose of the utility model provides the anticollision device, collision-prevention device of pier in a kind of highway bridge crossing; Can take into account crashproof and guide function, can effectively reduce pier collision accident in the highway bridge crossing, casualties and property loss that second accident such as reduce that the highway bridge crossing collapses causes; Simultaneously offset the impact of automobile effectively, prevent or reduce the damage of vehicle guardrail.
The purpose of the utility model realizes through following technical scheme: the anticollision device, collision-prevention device of pier in a kind of highway bridge crossing; Comprise the crashproof framework that is arranged on the Zhong Dun both sides along the highway direction; Said crashproof framework comprises four principal posts that are 2 * 2 arranged; Principal post vertically is provided with, and the lower end is fixedly imbedded in the ground, between circumferentially adjacent principal post, fixedly installs connecting rod.
Further, it is closely knit that said principal post is all used the C30 concrete casting;
Further, said principal post is 3.6 meters long, the seamless steel pipe of Ф 273,1.6 meters of principal post buried depths, 2 meters above ground level;
Further, said connecting rod adopts the seamless steel pipe of Ф 133;
Further, said middle pier is 0.5 meter apart from the minimum distance of crashproof framework;
Further, said principal post and connecting rod external coating polyurethane top coat layer;
Further, on the said crashproof framework reflective membrane is set.
The beneficial effect of the utility model: 1. the utility model can prevent effectively that through crashproof framework is set vehicle collision from damaging pier in the feed bridge crossing, avoids the generation of second accident.2. the utility model can effectively reduce collision energy through crashproof framework is set, and the guardrail deformation energy is in time recovered, and permanent set is little simultaneously, and is less to the damage of vehicle and guardrail facility.3. this anticollision device, collision-prevention device can utilize the plastic strain of steel framework and concrete deadweight to stop vehicle when more large-tonnage vehicle collision is arranged, and prevents pier in the highway bridge crossing is damaged.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the vertical view of the utility model location layout;
Fig. 2 is the structural representation of the utility model.
The specific embodiment
Fig. 1 is the vertical view of the utility model location layout; Fig. 2 is the structural representation of the utility model.As shown in the figure: the anticollision device, collision-prevention device of pier in a kind of highway bridge crossing, comprise the crashproof framework that is arranged on middle pier 3 both sides along the highway direction, said middle pier is 0.5 meter apart from the minimum distance of crashproof framework; Said crashproof framework comprises four principal posts 1 that are 2 * 2 arranged, and principal post vertically is provided with, and the lower end is fixedly imbedded in the ground, and in the present embodiment, said principal post is 3.6 meters long, the seamless steel pipe of Ф 273,1.6 meters of principal post buried depths, 2 meters above ground level; Between circumferentially adjacent principal post, fixedly install connecting rod 2; Said connecting rod adopts the seamless steel pipe of Ф 133.This anticollision device, collision-prevention device can prevent effectively that through crashproof framework is set vehicle collision from damaging pier in the feed bridge crossing, avoids the generation of second accident; Simultaneously can effectively reduce collision energy, the guardrail deformation energy is in time recovered, and permanent set is little simultaneously, and is less to the damage of vehicle and guardrail facility; When more large-tonnage vehicle collision is arranged, can utilize the plastic strain of steel framework and concrete deadweight to stop vehicle, prevent pier in the highway bridge crossing is damaged.
As the further improvement to the foregoing description, said principal post all uses the C30 concrete casting closely knit.Further improve the rigidity of principal post, help to improve the crashproof ability of principal post.
As further improvement to the foregoing description, said principal post and connecting rod external coating polyurethane top coat layer.Brushing polyurethane top coat layer prevents the rainwater corrosion, the application life that helps to improve anticollision device, collision-prevention device.
As further improvement, on the said crashproof framework reflective membrane is set to the foregoing description.Reflective membrane is set points out the driver at any time, especially improve driving at night safety.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
