Plug-in and pull-out guardrail (sheet) Plug-in and pull-out guardrail net is a kind of highway steel guardrail. Its structure is to divide the original guardrail column into upper and lower parts, and the lower end of the steel pipe of the upper column is covered with the lower one. There are bolts crossing the upper end of the steel pipe of the column to connect the upper and lower column steel pipes together. It prevents the deformation of the lower guardrail column by strengthening the lower column, that is, using casing or other processes, and at the same time partially weakens the upper column. Or completely weakened to control the deformation position of the guardrail column. In this way, although the moment arm is reduced, the cross-section bending modulus is also reduced at the same time, thereby ensuring that the anti-collision level is not lower than the original standard design. This guardrail is easy to construct, and after a vehicle collision It can be easily replaced and is not only suitable for soil shoulders, retaining walls and bridges, but also for various forms of steel guardrails
