Installation sequence and steps of high-speed guardrail board
The installation of high-speed guardrail panels is not a simple task, and the protective effect of guardrail panels cannot be exerted if the installation effect is not up to the standard. Therefore, it is very important to control the installation quality of the guardrail, so what aspects should be paid attention to in the acceptance standard of the guardrail? How can the installation effect be guaranteed?
We need to pay attention to the following aspects and ensure the installation steps of the guardrail board in the following aspects
1. The installation sequence of the guardrail must be correct. Only the correct installation steps can ensure the perfect splicing and installation progress of the guardrail. The preparation work before installation should be done well, check whether the type of guardrail is three-wave guardrail or two-wave guardrail, because the columns required are different. Preparations for various installation tools must be in place. Otherwise, it would be very time-consuming to find tools temporarily.
2. Construction stakeout
The work of installing the guardrail foundation is to fix the position of the column. We need to measure and determine the position of the column before piling. The location of piling needs to avoid public facilities such as underground optical cables.
3. Piling work of guardrail board column
Before piling, it is necessary to determine whether the soil quality of the piling site is suitable for the pouring conditions, otherwise it will affect the protective effect of the guardrail. It is also necessary to check whether the piling position is parallel to the roadbed.
4. Installation of bracket and anti-blocking block
After the column is fixed, you can install the bracket and the anti-blocking block. When you need to pay attention to whether the anti-blocking block, the bracket and the column match, because the model and the different one cannot be installed. The three-wave guardrail board and the two-wave guardrail board column, guardrail board, anti-blocking block, and bracket models are different.
5. Splicing of guardrail board
Then we can install the guardrail board, the splicing of the guardrail board needs to be seamlessly spliced. It is forbidden to drag the guardrail when transporting it, because its surface has a sprayed or galvanized layer, which will damage the surface and lose its anti-corrosion effect.
