BACKGROUND

[0002] In a floodable bridge engineering, the design and installation of the guardrail need to ensure the division of the passing area and the good flood discharge performance under extreme conditions such as flood. The floodable bridge guardrail needs to be removed when the flood comes so as to discharge the flood and avoid blocking the floating objects.

[0003] The existing floodable bridge guardrail adopts the bolt connection between the guardrail bottom steel plate and the base embedded steel plate. Before the flood comes, the bridge workers use tools to remove the connecting bolts between the guardrail bottom steel plate and the base embedded steel plate, separate the guardrail from the base embedded steel plate, move the guardrail to a safe position in sections for storage, and then pull back and install the guardrail at the original position after the flood recedes. The removal mode of the floodable bridge guardrail with the above structure has many problems, such as the long and heavy single section of the guardrail, the difficulty of manual lifting, the need for hoisting machinery, the long time for moving the guardrail after being removed, the inability to complete the removal in time due to the rapid flood, the need for finding a spacious and safe place for storing the guardrail, the occupation of space and the risk of loss, and the time-consuming and labor-consuming and resource-wasting for reinstalling the guardrail after the flood period.
