When installing, it is necessary to pass through sleeves, tie rods, and fastening nuts, and there are certain potential safety hazards in the connection of tie rods. In addition, the residual holes after the removal of tie rods need to be plugged twice, which is likely to cause quality problems such as slurry leakage, root rot, water seepage, and steel bar corrosion. The secondary repair also affects the appearance of the overall anti - collision guardrail.
