Abstract
The invention discloses a collision-resistant anti-rollover-crash expressway guardrail structure, which comprises expressway frames (1) and guiderails (3), wherein heel posts of the expressway frames (1) are made by piling and casting cement reinforced concrete in situ; the upper ends of the heel posts are provided with longitudinal beams and transverse beams; the longitudinal beams and the transverse beams are made by erecting and casting cement reinforced concrete in situ; the longitudinal beams on both sides are provided with the guiderails (3); the longitudinal beams and the transverse beams are made by erecting cement reinforced concrete cast-in-place floors, or are cast into a whole in situ by using cement concrete; the inner sides of the guiderails (3) on both sides are vertical, so that rollover crash caused by slippage of vehicle wheels is prevented; the outer sides of the guiderails (3) on both sides are semi-triangular, so that a reinforcing effect is achieved; and smart lines (4) are arranged at the upper ends of the guiderails (3) on both sides, so that drivers suffering from mental fatigue are prompted at any time.
Description
(1) technical field
The present invention relates to the improvement invention of freeway guardrail structure.
(2) background technology
Along with the demand of social development, popularize the developing speedway imperative.But, the lower overhead Frequent Accidents of the oversize vehicle that the overhead reinforced concrete ten guardrail sections of existing speedway are travelled, particularly motor bus rollover pendant, cause the group to die pernicious traffic accident that the group hinders.The crooked road of speedway, the gradient that the oversize vehicle rollover pendant car traffic accident majority of running on expressway occurs in the mountain area are many, and rainy season increased the driver under the condition such as sky weather and held the difficulty of the speed of a motor vehicle and direction in the process of driving, but at the oversize vehicle that the overhead reinforced concrete fence section in high speed main road, plains region runs the traffic accident of rollover pendant car occurs often.Although freeway guardrail is designed to arc toroidal, intuitively attractive in appearance, generous, can avoid again vehicle enclosure to be built by factors such as guardrail scratches.For this reason, the inventor is according to thought in rule and the characteristics of the traffic accident of the overhead reinforced concrete ten guardrail section generation oversize vehicles rollover of high speed pendant car in the past: the inboard hypomere of speedway guardrails of both sides is designed to the arc toroidal, and cutting flat several centimeters height that stay of formula at the guardrail root, this class formation moulding is enough to the hidden danger that causes traffic accident to occur.Reason: a. vehicle travels at highways in mountain areas and often often can run into crooked road Ackermann steer angle to comply with the guardrail side current, if do not cause car body to the right or left side-turning falls the car traffic accident in case the driver does not know well partially according to pasting that guardrail causes right side or left side wheel to be climbed up being slided on the circular foot washing basin of guardrail arc and guardrail sidecar wheel being pressed in the car to this location.B. vehicle when speedway overhead concrete guardrail section in plains region is travelled to the right or the left side surpass near guardrail, or the driver long-distance drive to make affect mental fatigue and make vehicle rely on that guardrail is current to be caused right side or left side wheel to be climbed up being skidded continuously on the circular foot washing basin of guardrail arc getting off to cause vehicle body acutely to rock, but left side or right side wheels are still before guardrail and then produced left and right sides wheel operation contradiction cause the turning on one's side major traffic accidents of pendant car.
(3) summary of the invention
In view of the defective that prior art exists, the present invention aims to provide a kind of crashworthiness anti-rollover pendant overall height speed highway barrier structure, and it is anti-skidding that this technology efficiently solves freeway guardrail, guarantees that the safety of all kinds of oversize vehicles on the speedway is exercised.
The present invention finishes as follows: a kind of crashworthiness anti-rollover pendant overall height speed highway barrier structure, comprise speedway frame, guardrail, described speedway trestle pin adopts the cement concrete pavement cast-in-place building of driving piles, the suspension column upper end arranges in length and breadth beam, beam adopts the cement concrete pavement frame to take cast-in-place building in length and breadth, two side girders arrange guardrail, and the cast-in-place grillage of beam employing cement concrete pavement is built and built in length and breadth, or use the cast-in-place one-tenth of screw-thread steel cement concrete whole.
Described guardrails of both sides is inboard vertical, and the outside becomes half triangle, prevents that wheel-slip from causing the vehicle-falling over accident of turning on one's side.
Smart wire is established in described guardrails of both sides upper end, reminds at any time driver's effect of mental fatigue.
A kind of crashworthiness anti-rollover pendant overall height speed highway barrier structure by theme design of the present invention, rational in infrastructure, be convenient to the practice building, improve the inboard anti-skidding arc toroidal of guardrail, improve driving safety, effectively control and reduce the major traffic accidents generation of oversize vehicle rollover pendant car.
(4) description of drawings
The present invention has following accompanying drawing
Fig. 1 crashworthiness anti-rollover pendant of the present invention overall height speed highway barrier structure positive view
(5) specific embodiment
Accompanying drawing discloses the technology of the present invention structure, the below describes in further detail embodiment more by reference to the accompanying drawings: comprise speedway frame (1), guardrail (3), described speedway frame (1) suspension column adopts the cement concrete pavement cast-in-place building of driving piles, the suspension column upper end arranges longitudinal and cross beam, adopt the cement concrete pavement frame to take cast-in-place building on the longitudinal and cross beam, two side girders arrange guardrail (3), guardrail (3) skeleton uses coarse-pitch thread steel bending forming, gradient in the coarse-pitch thread steel lateral, improve the effect of strong push rod support, guardrail (3) coarse-pitch thread steel frame is inboard vertical, play the pulling force effect, can prevent wheel-slip again, in the coarse-pitch thread steel frame, lower end, the outside is connected on the coarse-pitch thread steel that exposes on two side girders and is welded and fixed with electric welding, cross with middle frame with the screw-thread steel built again and be connected on the firm integral body of formation on guardrail (3) the coarse-pitch thread steel frame, then use electric welding to fix, adopting the cast-in-place grillage of cement concrete pavement to build on the longitudinal and cross beam builds, outside Bars In Poured Concrete Slab is laid screw-thread steel and is connected in guardrails of both sides (3) the coarse-pitch thread steel frame and with electric welding, be welded and fixed again, improve whole pulling force, or be welded and fixed outside using first the screw-thread steel laying and being connected in guardrails of both sides (3) the coarse-pitch thread steel frame and with electric welding, improve whole pulling force, then whole with the cast-in-place one-tenth of cement concrete; Described guardrails of both sides (3) shape is designed to inboard vertical, play and prevent that wheel of vehicle from skidding and cause the effect of rollover pendant car, guardrails of both sides (3) outside becomes half triangle, play and strengthen the crashworthiness effect, guardrails of both sides (3) upper end arranges smart wire (4), smart wire (4) is arranged on inboard, guardrails of both sides (3) upper end and slightly protrudes round frame, plays driver's effect of reminding at any time mental fatigue.
