Guardrail plate is commonly used on the highway guardrail plate, highway guardrail plate is the use of wave-forms for the main anti-collision components, it is steel and flexible can reduce the vehicle in the collision caused by the damage caused by the guardrail plate, which is produce by the Metal Guardrail Roll Forming Machine.
Principle of highway guardrail plate: highway guardrail plate is a corrugated steel guardrail plate spliced and supported by the main column of the continuous structure. It uses the deformation of the soil base, columns, beams to absorb the collision energy, and force the out-of-control vehicle to change direction, return to the normal direction of travel history, to prevent the vehicle from running out of the road to protect the vehicle and passengers, reduce the loss of ocarina caused by the accident.
In order to maintain the integrity of all parts of the roadbed, to the extent that the integrity of the roadbed to ensure the stability of the guardrail plate, so that the roadbed is often in good condition, at the time shall check the entire section of the roadbed. Check the work is located in the face of the wall, interceptor ditch, drainage ditch, hanging ditch, hole, side ditch outside 4m ~ 5m position, serious fill road condition record. In order to repair the problem in time, only in this way can effectively ensure that there is no damage to the guardrail plate columns on both sides of the highway, and at the same time to ensure the integrity of the entire guardrail plate system. Then how to carry out the maintenance of the roadbed?
The thickness and uniformity of the galvanized layer then directly affects the service life of the waveform beam. If any serious situation is found, the processing procedure of the manufacturer must be checked immediately; for the sign board, first check whether the base plate material is in accordance with the relevant regulations, and then test its chromaticity performance, luminosity performance, retro-reflection coefficient, luminous intensity coefficient, maroon resistance, bending resistance, and anti-corrosive treatment, etc.. The main check on the marking line marking material reflective properties, adhesion, etc., the main check on the appearance of the grille size and anti-corrosion treatment, etc..
Strengthen the control of the process flow to the quality of the guardrail plate, eliminating the occurrence of unqualified processes implied in the project, such as waveform beam steel guardrail construction process for: sampling - piling - guardrail installation - guardrail line adjustment.
