Bridge Highway cast steel bearing pedestrian River railing support cast iron welded guardrail support

  Guardrail support is a facility to close both sides along the line, and it is also a facility for people and other vehicles to break into the highway
It can reduce the destructive resistance, change the direction of the out of control vehicles, restore the original driving direction, and prevent them from falling under the bridge
Guardrail anti-collision can be divided into rigid guardrail and flexible guardrail
Anti collision guardrail is also a necessary facility of the expressway, which has an impact on the safety, comfort and project cost of the expressway
When constructing the expressway, it is necessary to fully understand various anti-collision mechanisms and costs, as well as the degree of construction simplicity and maintenance costs
The choice of which kind of anti-collision guardrail to use for the expressway should be made in combination with the specific engineering conditions
During the construction of the bridge guardrail, the steel pipe support with full bowl mouth shall be used as the support, the concrete cushion block shall be laid at the bottom of the steel pipe, and the square timber shall be laid at the top of the support
At the same time, a detailed erection and dismantling design and construction scheme shall be made for the whole bridge support, and the structural mechanics calculation shall be carried out
The construction scheme shall be reported to the supervising engineer for approval
It is also necessary to check whether the technical indicators, specifications and dimensions of the products meet the requirements of the drawings
Please indicate the main functions of the bridge for reprint
1 Bridge guardrail refers to the guardrail set on the bridge
Its purpose is to prevent out of control vehicles from crossing the bridge
It has the function of preventing vehicles from breaking through, crossing, crossing the bridge and beautifying the bridge building

2
for the selection of the form of bridge guardrail, the anti-collision grade shall be determined by comprehensively considering the safety, coordination, characteristics of the objects to be protected, site geometric conditions and other factors according to the highway grade, and then the structural form shall be selected according to its own structure, economy, construction, maintenance and repair and other factors

3
The embedment methods include column direct embedment, flange connection and casting the bridge guardrail and bridge deck into a whole through force transfer reinforcement
If conditions permit, the replacement guardrail can be used
