As a common traffic safety facility, the installation method of crowd barriers is of great significance to ensuring road safety and maintaining traffic order. The following is a detailed description of the installation method of crowd barriers:
Installation method of crowd barriers
I. Preliminary preparation
Determine the scope of construction:
Before installing crowd barriers, it is necessary to first clarify the specific scope of construction. This requires considering the safety requirements of vehicles and personnel, while also taking into account aesthetics and practicality.
According to factors such as road conditions, traffic flow and surrounding environment, the layout and number of crowd barriers should be reasonably planned.
Measure the elevation and design the foundation:
Use measuring tools to measure the elevation of the construction area to ensure that the installation height of the crowd barriers meets the standards.
Design the foundation according to the soil conditions and geographical environment, and choose the appropriate foundation type and depth. Generally, a hemispherical pit is a common foundation design type.
Purchase an appropriate amount of concrete materials to prepare for subsequent foundation pouring.
Clean up the construction area:
After digging the pit, clean up the construction area in time to ensure that the construction environment is clean and orderly.
Place construction tools and equipment in designated locations for subsequent operations.
2. Foundation pouring and fixing
Pouring concrete foundation:
According to the design requirements, pour concrete in the excavated pit. Ensure that the concrete quality is qualified, pay attention to vibrating and compacting during pouring to avoid voids and cracks.
After pouring, let the concrete foundation dry naturally for at least 72 hours to ensure its strength and stability.
Fix the guardrail posts:
After the concrete foundation is dry, start fixing the crowd barrier posts. Place the posts in the predetermined position according to the design requirements, and use tools such as a level to adjust their height and inclination.
Use bolts or other fixings to firmly fix the guardrail posts to the concrete foundation to ensure that they will not shake or tilt due to external forces.
3. Guardrail construction and reinforcement
Build guardrails:
After fixing the guardrail posts, start installing the guardrail panels. Insert the guardrail panels into the guardrail posts in order and fix them to the posts with bolts or other connectors.
Pay attention to check whether the guardrail panels are installed flat and firmly to avoid looseness or dislocation.
Installation accessories and reinforcement:
Install accessories of the iron horse guardrail as needed, such as screws, expansion tubes, clamps, etc. These accessories can enhance the stability and safety of the guardrail.
Use welding or bolting to reinforce the guardrail to ensure that it can remain stable when facing external force impact.
4. Subsequent inspection and maintenance
Performance and safety test:
After installation, perform performance and safety tests on the crowd barrier. Check its stability, durability and compliance with relevant standards and requirements.
If any problems or hidden dangers are found, deal with and repair them in time.
Regular inspection and maintenance:
During use, regularly inspect and maintain the crowd barrier. Check whether it is loose, damaged or rusted.
Clean the dirt and debris on the surface of the guardrail in time to keep it clean and beautiful.
Replace or repair damaged or aging parts to ensure that the crowd barrier is always in good use.
In summary, the installation method of the crowd barrier includes multiple links such as preliminary preparation, foundation pouring and fixing, guardrail construction and reinforcement, and subsequent inspection and maintenance. Each link needs to be operated strictly in accordance with specifications and requirements to ensure the installation quality and use effect of the crowd barriers.
