For flood control embankment guardrails, reversible steps are set at the bottom. They are retracted in normal times and put down during the flood season to form an emergency rescue passage. The aluminum alloy steps are 60 cm wide and can bear a load of 300 kg per square meter. Quick-disassembly sections are set at key nodes, and 10 meters can be removed in 5 minutes. The river guardrail beside the ancient city wall ruins needs to be coordinated with the style of the city wall. City-brick-colored clay railings are used, and the surface is aged to imitate the texture of the ancient city wall. The firing temperature of the clay railings is 1200 degrees Celsius, the compressive strength is 50 MPa, and the water absorption rate is ≤ 8%. The shape of the railings imitates the stone railings of the Ming Dynasty. The balustrades are carved with scroll grass patterns, and the capitals of the balusters are lotus seats. During installation, the traditional mortise and tenon structure is used, and tung oil mortar is used for caulking. The guardrail foundation is hidden underground without destroying the style of the ruins. Each clay railing has an antique mark, which blends in with the ancient city wall.

For cable-stayed bridge guardrails, an annular rubber sealing sleeve is set at the cable duct, and a lap joint transition section with a length of 2 meters is used at the disconnection. The height near the cable tower gradually changes to 1.5 meters. CNC cutting ensures a smooth arc, and the white coating is unified with the cables to reduce visual fatigue. For emergency escape bridge guardrails, quickly openable escape doors are set at specific sections. The door is 1 meter wide and 1.8 meters high. It is locked in normal times and flush with the guardrail without affecting the anti-collision function. In an emergency, pressing the handle can trigger the pneumatic device, and the door will be popped open 30 degrees within 0.5 seconds. A slow-down slide or a folding staircase is connected behind the door for people to evacuate to the safe area under the bridge. An escape door is set every 200 meters, and there are reflective signs for indication. The control system is linked with the bridge fire alarm. Once the detector is triggered, all escape doors will be automatically unlocked. A functional test is carried out once a month to ensure that the mechanical components are flexible and reliable.
