Sprayed corrugated guardrail panel is a common road safety facility, and its specifications and standards are of great significance for ensuring road traffic safety. This article will introduce in detail the specifications and standards of sprayed corrugated guardrail panels from the aspects of materials, manufacturing processes, installation and construction, and acceptance standards.
First, the material standard.
The main material of sprayed corrugated guardrail board is high-quality steel plate, and its thickness, strength, corrosion resistance and other performance indicators should meet the relevant standards. The surface of the steel plate should be flat and smooth, without obvious concave and convex, cracks and other defects. At the same time, the coatings used should meet environmental protection requirements and have good weather resistance, corrosion resistance and adhesion.
Second, the manufacturing process standard.
The manufacturing process of spraying corrugated guardrail board includes cutting, forming, welding, grinding, spraying and other processes. In the manufacturing process, it should be ensured that the steel plate is cut accurately, the forming is beautiful, the welding is firm, and the grinding is smooth. The spraying process should use high-quality coatings to ensure that the coating is uniform and smooth, and there are no defects such as bubbles and cracks.
3. Installation and construction standards.
The installation and construction of sprayed corrugated guardrail panels should follow the following standards:
1.According to the road width and design requirements, determine the length and spacing of the guardrail plate to ensure that the installation is firm and beautiful.
2.Before installation, the foundation should be leveled and tamped to ensure the stability of the foundation and prevent the guardrail board from shaking or tilting after installation.
3.Attention should be paid to adjusting the angle and height of the guardrail plate during installation to ensure that it is consistent with the road alignment and has no obvious twisting or deformation.
4.After the installation is completed, the guardrail board should be checked to check whether it meets the design requirements and whether there is any damage or deformation.
Fourth, the acceptance criteria.
The acceptance criteria for sprayed corrugated guardrail panels mainly include the following aspects:
1.Appearance quality: The surface of the guardrail board should be flat and smooth, with uniform coating and no bubbles, cracks and other defects.
2.Dimensional deviation: The dimensional deviation of the guardrail board should comply with relevant standards, including length, width, height, etc.
3.Installation quality: The installation of the guardrail plate should be firm and stable, consistent with the road alignment, without obvious distortion or deformation.
4.Anti-corrosion performance: The guardrail board should have good corrosion resistance and be able to maintain its appearance and quality for a long time.
5. Other precautions.
In the manufacturing and installation process of spray corrugated guardrail panels, the following points should also be noted:
1.Manufacturing and installation personnel should have the appropriate skills and knowledge to ensure product quality and construction safety.
2.In the process of manufacturing and installation, relevant laws, regulations and standards should be complied with to ensure product quality and construction safety.
3.During use, the guardrail board should be regularly inspected and maintained to ensure that it is always in good condition and effective.
In short, the specification standard of sprayed corrugated guardrail board is of great significance for ensuring road traffic safety. In the process of manufacturing and installation, relevant standards and requirements should be strictly adhered to to ensure product quality and construction safety. During use, it should be checked and maintained regularly to ensure that it is always in good condition and effective.
