The utility model provides a technical scheme that its technical problem adopted is:
a self-reset waveform guardrail comprises an upright post and a waveform beam guardrail plate, wherein the lower end of the upright post is connected with the ground, the waveform beam guardrail plate is connected with the side surface of the upright post, a guardrail plate spring is arranged between the waveform beam guardrail plate and the upright post, and the waveform beam guardrail plate is connected with the upright post through the guardrail plate spring.
In the above scheme, the self-resetting waveform guardrail further comprises a flange plate, the flange plate is fixed on the ground, and the lower end of the stand column is fixedly connected with the flange plate.
In the scheme, the flange plate is fixed on the ground through the foundation bolts, and the foundation springs are sleeved on the screw rods between the nuts of the foundation bolts and the flange plate.
In the scheme, the self-resetting corrugated guardrail further comprises angle steel embedded underground, the lower end of each foundation bolt is fixedly connected with the horizontal plane of the angle steel, and the vertical plane of the angle steel is located on one side of the corrugated beam guardrail plate of the angle steel.
In the scheme, the flange plate is provided with a U-shaped hole, a screw rod of the foundation bolt penetrates through the U-shaped hole to be anchored underground, and a long shaft of the U-shaped hole is perpendicular to the corrugated beam guardrail plate.
In the scheme, the nut is arranged below the horizontal plane of the angle steel, and the lower end of the foundation bolt is fixedly connected with the angle steel through the nut.
The utility model discloses beneficial effect: compared with the prior art, the utility model discloses can the effective absorption vehicle collision guardrail the energy, simple structure, manufacturing cost is lower, suffers the self-recovery ability after the vehicle collision strong.

Detailed Description
In order to make the purpose and technical solution of the present invention clearer and clearer, the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2 the utility model discloses from waveform guardrail embodiment that restores to throne, it includes stand 3, 1 ring flange 7 of waveform beam guardrail board and angle steel 6, and the lower extreme and the ground of stand 3 are connected, and waveform beam guardrail board 1 is connected with 3 sides of stand, and be equipped with two or more guardrail plate spring 2 about being equipped with between waveform beam guardrail board 1 and the stand 3, and waveform beam guardrail board 1 passes through guardrail plate spring 2 and is connected with stand 3.
The flange 7 is fixed on the ground, and the lower end of the upright post 3 is connected with the flange 7 in a welding way. The flange plate 7 is fixed on the ground through four foundation bolts 5, and foundation springs 4 are sleeved on screw rods between nuts of the foundation bolts 5 and the flange plate 7.
The angle steel 6 is buried underground, a nut is arranged below the horizontal plane of the angle steel 6, and the lower end of the foundation bolt 5 is fixedly connected with the angle steel 6 through the nut.
The rigidity of the guardrail plate spring 2 is smaller than that of the foundation spring 4.
As shown in fig. 3, the flange 7 is provided with a U-shaped hole 8, the screw of the anchor bolt 5 passes through the U-shaped hole 8 and is anchored underground, and the long axis of the U-shaped hole 8 is perpendicular to the corrugated beam guardrail plate 1.
As shown in fig. 4, the lower end of the anchor bolt 5 is fixedly connected with the horizontal plane (long side) of the angle steel 6, and the vertical plane (short side) of the angle steel 6 is positioned on the side of the corrugated beam guardrail plate 1 of the angle steel.
When a vehicle collides with the embodiment of the utility model, the wave beam guardrail plate 1 firstly deforms under the action of the collision force, and meanwhile, the guardrail plate spring 2 also compresses and deforms under the action of the collision force to consume energy; then the upright post inclines along the U-shaped hole 8 on the flange 7 under the collision force, at the moment, the ground spring 4 is compressed and deformed to consume more collision energy, and in the process, the guardrail plate spring 2 and the ground spring 4 exert reverse acting force on the collided vehicle due to the super-elasticity performance so that the vehicle is restored to the correct running direction; finally, the collision force of the vehicle is transmitted to the angle steel 6 through the foundation bolt to deform the angle steel and consume energy; after the vehicle is recovered to a correct traffic lane, the guardrail plate spring 2 and the anchor spring 4 are automatically reset to the original positions due to the shape memory performance, and a certain protection effect is continuously exerted.
The embodiment of the utility model provides a be tertiary energy-absorbing structure, and simple structure is convenient for install, and manufacturing cost is lower. The spring that sets up can provide hyperelastic guiding force and guarantee to travel to the exact direction after the vehicle collides the guardrail, its shape memory performance can make the guardrail resume the position before the collision after the vehicle breaks away from the guardrail simultaneously, can also carry certain guard action after guaranteeing the guardrail collision to guardrail plate spring 2 and lower margin spring 4 are made for shape memory alloy, have fine corrosion resistance, but cyclic utilization satisfies resources are saved, green endless requirement.
It should be noted that the above description is only a preferred embodiment of the present invention, and that those skilled in the art can make various similar representations without departing from the spirit and the scope of the present invention.
