Description

Technical Field

[0001] The utility model belongs to the technical field of municipal roads, and more specifically, particularly relates to a municipal road and bridge engineering guardrail. Background Art

[0002] There are pavements and bridges in municipal roads. Bridges need to be equipped with guardrails when in use. Bridge guardrails prevent vehicles and pedestrians from falling from the bridge into the river. Bridge guardrails are installed on the edge of the bridge. The guardrails are inspected and maintained regularly to ensure long-term use of the guardrails.

[0003] According to 202120171394.2, the utility model discloses a road bridge safety anti-collision guardrail, including two guardrail beams and multiple anti-collision columns, the two guardrail beams are arranged in parallel up and down; multiple anti-collision columns are arranged between the two guardrail beams at intervals from left to right, and anti-collision buffer mechanisms are arranged at both ends of the anti-collision columns, and the anti-collision buffer mechanism includes a buffer inner ring sleeve connected to the anti-collision column, a buffer outer ring sleeve fixed on the guardrail beam, and multiple elastic buffers, the buffer outer ring sleeve is coaxially arranged with the buffer inner ring sleeve, and the buffer outer ring sleeve is arranged on the periphery of the buffer inner ring sleeve, and multiple elastic buffers are radially annularly spaced between the buffer inner ring sleeve and the buffer outer ring sleeve. When the anti-collision column is hit in different directions horizontally, the impact force can be buffered, so that the vehicle impact force can be buffered in multiple directions, improving the effect of anti-collision buffering. The utility model can be applied to municipal road and bridge projects.

[0004] Based on the above, the existing bridge guardrails are generally installed on the edge of the bridge, and the height between the bridge and the river is relatively high.

The impact force of jumping from the bridge into the river is relatively large, which can easily cause physical injuries to the rescue personnel, and running from the bridge to the river wastes a long time for rescue.
