What is the application of the guardrail forming machine?

Guardrails are commonly used guardrails on highways. Highway guardrails use waveforms as the main anti-collision components. Its steel and soft phases can reduce the loss caused by vehicles when they hit the guardrail.

The principle of the highway guardrail board: The highway guardrail board is a continuous structure with corrugated steel guardrail boards spliced with each other and supported by the main column. It uses the deformation of soil foundations, columns, and beams to absorb collision energy, and forces out-of-control vehicles to change directions and return to their normal travel directions, preventing vehicles from rushing out of the road, protecting vehicles and passengers, and reducing loss caused by accidents.

In order to maintain the integrity of each part of the roadbed, to a certain extent, the integrity of the roadbed ensures the stability of the guardrail, so that the roadbed is always in good condition, and the entire section of the roadbed must be inspected in time. The inspection work is located at a position 4m～5m outside of the face wall, intercepting ditch, drainage ditch, hanging ditch, hole, and side ditch, and the condition of the severely filled pavement is recorded. In order to fix the problem in time, only in this way can it effectively ensure that the guardrail posts on both sides of the highway are not damaged, and at the same time ensure the integrity of the entire guardrail system. So how to maintain the roadbed?

The thickness and uniformity of the galvanized layer directly affect the service life of the corrugated beam. If a serious situation is found, the manufacturer's processing procedures must be checked immediately; for the sign board, first check whether the bottom plate material meets the relevant regulations, and then test its chromaticity performance, luminosity performance, retroreflective coefficient, luminous intensity coefficient, weather resistance, and durability. Bending performance and anti-corrosion treatment, etc. For markings, the reflective performance and adhesion of the marking materials are mainly checked, and for the isolation barriers, the appearance dimensions and anti-corrosion treatments are mainly checked. Strengthen the control of the process flow to control the quality of the guardrail board and eliminate the occurrence of unqualified processes implicit in the project. For example, the construction process of the corrugated beam steel guardrail is: lofting-piling-guardrail installation-guardrail alignment adjustment.
