Recently, many people are more interested in the installation methods of bridge metal guardrails, in order to meet everyone's needs, let's talk about it, if you are interested, you can learn about it.
The main installation methods of bridge metal guardrails are as follows:
1. Anchor installation: fix the foundation of the guardrail on the bridge with anchors to ensure the stability and firmness of the guardrail. This installation method is suitable for tall bridges, which require the use of mechanical equipment for construction.
Process flow: determine the location and type of guardrail;
Beat to determine the anchorage position;
install anchors;
fixed columns and beams;
adjust the horizontality and verticality of the guardrail;
welded or bolted guardrail panels;
Acceptance, check the installation quality of the guardrail.
Acceptance criteria: the guardrail is firmly connected with the foundation, and there can be no obvious loosening;
The gaps between the guardrail panels should meet the specified standards;
The surface of the guardrail should be flat, without obvious concave and convex and deformed;
The protective layer should be evenly brushed, without blistering and peeling.
2.Roadside installation: Install the guardrail directly on the roadside of the bridge without the need for anchoring. This type of installation is suitable for low bridge heights.
Process flow: determine the location and type of guardrail;
installation of columns and beams;
adjust the horizontality and verticality of the guardrail;
welded or bolted guardrail panels;
Acceptance, check the installation quality of the guardrail.
The acceptance criteria are similar to those for anchored installations.
3.Suspended installation: The guardrail is suspended on the beam of the bridge, and the construction is carried out using hoisting equipment. This installation method is suitable for situations where the bridge height is too high to be anchored.
Process flow: determine the location and type of guardrail;
installation of hoisting equipment;
Lifting guardrails; adjust the horizontality and verticality of the guardrail;
welded or bolted guardrail panels;
Acceptance, check the installation quality of the guardrail.
The acceptance criteria are similar to those for anchored installations.
Different bridge metal guardrail installation methods have differences in process flow and acceptance criteria, but they should ensure the stability, firmness and compliance of the guardrail with the installation requirements.
