[0004] After searching: (1) Application No. / Patent No. 202211168767.6 discloses a highway anti-collision guardrail, including a support column, a guardrail body is fixedly installed on the outer side of the support column near the top, the guardrail body includes two parallel arc-shaped plates, the outer side of the arc-shaped plates has three ridges, and the inner side of one of the arc-shaped plates is fixedly installed with two symmetrically arranged extension bars, and the extension bars are fixedly connected to the adjacent guardrail body by bolts. When working, when the guardrail body receives an impact, it can deform itself to absorb momentum, and the setting of the extension bar, during the installation of the guardrail, the extension bar is inserted into the inner side of the adjacent guardrail body, and the extension bar is fixed to the inner side of the guardrail body with bolts from the outside. Compared with the traditional method of fixing only at the end of the connection, the entire guardrail can remain intact under impact and will not break easily, so that the out-of-control vehicle can be restricted on the road instead of rushing out of the road and causing greater damage.

[0005] (2) Application No. / Patent No. 201910156972.2 discloses a central guardrail of a highway, including a base, a column, a guardrail assembly, a mounting block, a limit block, a clamping block, a buffer spring, a return spring and a pull rod; the base is buried in the middle of the highway, the upper side of the base is located at the same horizontal plane as the highway surface, and a plurality of slide grooves are opened on the base; a plurality of limit blocks are arranged at the bottom of the slide groove, and two columns are slidably arranged on the slide groove; through the cooperation between the column, the guardrail assembly, the buffer spring and the clamping block, the buffer spring gradually absorbs the impact force of the vehicle and converts it into its own elastic potential energy, and the buffer spring cannot release the elastic force, so as to prevent the column from bouncing the vehicle back to the lane and causing further damage, thereby effectively absorbing the impact force of the vehicle and effectively reducing the degree of damage to the vehicle.

[0006] (3) Application No. / Patent No. 202110400925.5 discloses a highway anti-collision guardrail, which includes a guardrail plate horizontally arranged beside the highway, and at least two columns for fixing the guardrail plate are arranged on the guardrail plate in the length direction; a base buried in the ground is arranged at the lower end of the column, and a fixing assembly for fixing the column is also arranged between the base and the column; a buffer groove is provided on the upper surface of the base, and the fixing assembly includes a buffer block arranged in the buffer groove, and a buffer gap is left between the side wall of the buffer block and the inner side wall of the buffer groove, and a plurality of tension springs are also arranged in the buffer gap, and the tension spring is located on the side of the buffer block facing the highway, one end of the tension spring is fixedly connected to the buffer block, and the other end is fixedly connected to the inner wall of the buffer groove, and the lower end of the column is fixedly connected to the buffer block, and a cover plate is provided at the opening of the buffer groove, and a through hole is provided on the cover plate to accommodate the column to pass through. This application has the effect of reducing the damage to the accompanying personnel when the vehicle hits the guardrail.

[0007] The applicant has analyzed and found that the above technical solution solves the problem of anti-collision protection of the guardrail. However, in the actual construction process, the installation of the columns will not be in the same plane due to the influence of the construction terrain, which will make the installation of the corrugated guardrail body inconvenient.
