Bridge guardrails are important components of our bridge traffic. They not only decorate our bridges, but also play another important role in preventing vehicles or pedestrians from crossing the bridge deck due to accidents. This shows the important role of guardrails in daily life. Maintenance of guardrails is also very important after they are put into use, because guardrails may become loose over time or due to construction defects, which poses a hidden danger in our daily use. In addition, places where screws are used for installation may become loose over time.

So what should we do in post maintenance to eliminate security risks? What should I do if the guardrail is loose?

When the bridge guardrail becomes loose, we first connect the pier behind the bridge guardrail to a sturdy place, which will be very strong and provide excellent lateral pressure; To determine whether it is behind the pier or a railing, use tools to make the appearance appear as a backing. The most important thing is that the backing should be solid. If possible, check if it is a tripod or if the closure is installed behind the pier; Install a screw on the railing of the bridge guardrail to enter behind the pier, and first guide a hole on the small screw; When the pier needs to be fixed on the floor, leave a portion below and tie it up. Then, according to the application program, raise the drilled hole in a straight line to the bottom.
