Why is there a Rectangular planter box with guardrails on roads? Roads are divided into highways and streets. We can see that no matter it is a road or a street, there is generally a Rectangular planter box with guardrail.
The main purpose of installing a guardrail Rectangular planter box on the highway is to guide the vehicle to a certain extent and reduce the possibility of the vehicle rushing out of the road. Theoretically speaking, assuming that the vehicle is driving on a highway on the edge of a cliff, the Rectangular planter box with guardrail can give the driver a sense of psychological safety to a large extent. The experimental data shows that if there is no guiding function of the guardrail Rectangular planter box on the highway, there will be a high probability of vehicle collision, and the possibility of a secondary collision between the colliding vehicle and other normal driving vehicles will increase, resulting in more Serious road safety accident. Therefore, the state stipulates that a Rectangular planter box should be installed on both sides of the road to prevent the above situation.
Setting a reasonable guardrail Rectangular planter box on the highway can also reduce the severity of the accident as much as possible. For example, the common wave guardrail Rectangular planter box board on the highway uses the deformation of the soil foundation, pillars and beams to absorb the collision energy, and forces the out-of-control vehicle to change direction and return to the normal driving direction to prevent the vehicle from rushing out of the road to protect the vehicle And passengers to reduce the loss caused by the accident.
And another kind of guardrail Rectangular planter box, the road anti-collision rotating barrel pioneered a rotating structure, supporting the flexible and anti-collision and wear-resistant rotating barrel on the column, so that the rotating barrel can rotate freely on the column. This free rotation of the rotating bucket decomposes the impact force of the car, so that the impact force perpendicular to the direction of the guardrail Rectangular planter box is decomposed to a direction parallel to the direction of the guardrail Rectangular planter box, which is effectively absorbed and reduced by the rotating bucket, thereby effectively reducing traffic The consequences of the accident. The setting of the urban road guardrail Rectangular planter box is to a greater extent to effectively prevent pedestrians from crossing the road at will, and to prevent vehicles from driving on the sidewalk at will, so that vehicles and pedestrians are in the prescribed place, reducing the probability of traffic accidents and reducing The phenomenon of random parking of vehicles occurs.
