Description
Technical field:
The utility model is relevant with highway barrier, and is especially relevant with cable guard railing.
Background technology:
At present, domestic highway barrier form is varied, is divided into rigidity, semi-rigidity rail and flexible safety fence substantially.
Stiff safety fence adopts reinforced concrete structure more, its intensity height, and rigidity is big, when vehicle and its collision, vehicle and driver and crew is injured seriously, and cause second accident easily, has the accident rate of wound very high.
Semi-rigidity rail adopts steel structure, and its strength and stiffness is higher.At present, China is extensive use of, but has price height, installation, dismounting inconvenience, and shortcomings such as maintenance cost height are also higher to accident vehicle and personnel's injury in practice, the accident of wound arranged also than higher.
The principal mode of flexible safety fence is the cable guardrail, it is a kind of toughness guardrail with big buffer capacity, be fixed in structure on the column with several cables that apply initial tension, it mainly is the collision of resisting vehicle by the tensile stress of cable, absorbs collision energy, and cable is fixedlyed connected with column, injure all, the layout of cable makes resistance hurdle power single, stops the power point-load on the minority supporting member, damages supporting member easily.Exist to install, safeguard inconvenience, the expense height of installing, safeguarding, shortcoming such as the scope of application is little, and side-play amount is excessive.
In sum, all there is deficiency in above guardrail form, can not well satisfy the function and the requirement of highway barrier.
The content of utility model:
The purpose of this utility model has provided a kind of simple in structure, use, installation, easy to maintenance, and with low cost, security performance is good, the highway safety cable guard railing that repairing performance is good.
The utility model is achieved in that
The highway safety cable guard railing, constitute with some cable wires that are supported on the column 1 by some columns 1, the top of column 1 is supported with the cable wire 2 of at least one tensioning at least, column 1 towards with the side of highway dorsad on supporting arrangement 3 is arranged, at least one pair of cable wire 4 detours between column 1 along tensioning of guardrail direction and intersection, is bearing in respectively on the supporting arrangement 3 of a root post 1 two sides.
The cross section of column 1 is that S type Z type or I shape are circular or square, and groove 5 supporting top cable wires 2 are arranged at the top of column 1, and supporting arrangement 3 is alignment pin or positioning hanger.
A pair of cable wire 4 intersects or vertical direction intersects and detours on the supporting arrangement 3 that is supported on column in horizontal direction between the two adjacent upright 1.
The end of cable wire is fixed on terminal anchor post 6 or the middle anchor post 12.
Be connected with corrugated beam barrier 10 or parallel, the end of cable wire is fixed on the wave beams.
Cable wire between two columns 1 that automobile passes through disconnects, and is connected by rigging screw 7.
Column 1 is fixed with concrete lower margin 8 or is connected with slot 11 insertions of concrete lower margin 8, and there is reflective guard shield 9 on column 1 top.
Column top cable wire 2 is apart from ground 555mm-615mm, and the cable wire 4 in the column upper support device 3 is apart from ground 460-520mm.
Column top cable wire 2 is apart from ground 585mm, and the cable wire 4 in the supporting arrangement 3 is apart from ground 490mm.
The utlity model has following advantage:
1, speedway is carried out shunting and isolation, stop the outer vehicle of speedway, pedestrian, livestock etc. to pass through the road surface, the safety that the Dangerous Area of ordinary highway is improved vehicle ' is to avoid taking place traffic accident.
2, the impact of accident vehicle in the absorption road in that vehicle and driver and crew are being damaged under the minimum situation, stops accident vehicle to pass through outside isolation strip or the road, to avoid causing the great traffic story of car crash.
3, safety is good, and adopting the utility model to reduce greatly has the accident rate of wound.When accident vehicle bump the utility model, because different flexible cable that is provided with and the pulling force between column are formed a powerful elastic network(s), the crash energy of accident vehicle in it can absorb.Simultaneously, because pulling force increases between cable wire distortion column, and pulling force passed to adjacent a plurality of column, whole process is cumulative to the resistance of vehicle, the Impact energy of vehicle is reduced, cause vehicle to be got back to slowly on the track, allow possible car turn over people's accident of dying and be converted into less injury or do not have the injury minor accident.
4, reparation property is good, and the rehabilitation expense of the back guardrail that has an accident is low, and repairing efficiency is short, generally only damages column, does not damage wirerope.
5, indicate effectively, column, wirerope, upper shield all can be coated the coating of different colours, satisfy different requirements, and be all fine to the sign effect of the attractive in appearance and outline line of road.
6, price is low, and the utility model is simple in structure, makes, constructs and all can adopt mechanized to reduce cost, so overall cost is lower than the steel guardrail.
7, maintenance cost is low, only wirerope is carried out regular preservative treatment and gets final product.
In sum, use the utility model can improve the safety that road traffic vehicle travels greatly.Reduce highway construction cost, reduce and safeguard and cost of use, the increase road is attractive in appearance and indicate effect, accelerates highway construction.

The specific embodiment:
The utility model guardrail has many root posts 1 and four flexible cables 2,4 to install by the mode among Fig. 1 to be connected, and the spacing distance of column and the length of cable wire are decided according to the highway ground shape, and column item end guard shield 9 plays reflective board effect.
Two tensionings than high wire 2, it is by fluting 5 supportings on a lot of columns 1 top; The cross section of each column is S type or Z type, and the fillet of column is sailed next direction towards automobile like this; A pair of low cable wire 4 is tensioning along the guardrail direction, and they intersect detours between column; There is alignment pin 3 to be used for supporting this to low cable wire on the column at the height of regulation; Above-mentioned two than high wire and a pair of low cable wire can effectively postpone column 1 under automobile impacting distortion and collapse.
Disconnect at two cable wires that leave between the column 1 that automobile passes through, they are connected by the rigging screw that can untie fast 7, so just can provide automobile passage by guardrail.One end of cable wire is connected with corrugated beam barrier 10.Each column 1 has a concrete lower margin 8, and it allows column bending when being subjected to clashing into.Concrete lower margin 8 is prefabricated or cast-in-place, and the inside has slot 11 to be used for inserting column 1, the height of column in the time of so just guaranteeing to install, and maintenance is just fast very convenient.
The utility model can with corrugated beam barrier 10 parallel uses, like this, the highway safety cable guard railing is as the first road guardrail, corrugated beam barrier 10 is as the second road guardrail.The utility model than the height of high wire at 555mm between the 615mm, low cable wire at 460mm between the 520mm.Height than high wire preferably is set to 585mm, and the height of low cable wire preferably is set to 490mm.All cable wires are all with the 1000 power tensionings of arriving 5000KgF.Alignment pin 3 usefulness that all have each column decide the height of low cable wire.The end of cable wire is fixed on terminal anchoring pile 6 or the middle anchoring pile 12.
