The uncertainty of winter highway guardrail installation

The installation of highway guardrail is generally chosen in the spring and autumn seasons, mainly because the temperature is suitable in the spring and autumn seasons, while providing favorable guarantees for the transportation and installation of highway guardrail. If the construction of highway guardrail is chosen to be carried out in winter, there will be many difficulties in installation and transportation.

In winter, because the temperature is very low, the soil freezes. It is very difficult to shovel the frozen soil even with a shovel, and because of the freezing of the soil, the moisture in the soil is difficult to volatilize. If the support frame of the highway guardrail is placed in such soil, it is very easy to cause the corrosion of the support frame. At the same time, since the support frame is installed in the frozen soil, it will be replaced seasonally later, When the temperature rises and the soil freezes, the phenomenon of soil loosening will occur, which will cause the fixed support frame to loosen, resulting in the instability of the entire guardrail system. Therefore, choosing to construct in winter faces a very big challenge.

In addition, if you choose to install highway guardrail in winter, due to the low temperature and prolonged harsh weather conditions, it requires human willpower to maintain agile thinking. Once the thinking of construction personnel is wrong, the consequence is the deviation of construction data, which ultimately leads to the insecurity of the entire highway guardrail project. Strict data is required for construction and no errors can occur. So when choosing the construction time for highway guardrail, it is important to avoid installing them in winter as much as possible.
