Professional installation is the lifeline that ensures a rockfall protection net system performs as designed. Even a seemingly minor oversight can lead to complete system failure. This guide outlines the key installation steps and safety fundamentals, providing a blueprint for ensuring project quality.
Using a passive protection system (RXI type) as our example, we will demonstrate a typical professional installation process.
Step 1: Site Survey & Marking
Precisely measure and mark the locations of steel post foundations and anchor foundations according to the design drawings.
Clear the site to ensure the work area is unobstructed.
Step 2: Foundation Excavation & Pouring
Excavate foundation pits to the specified dimensions and depth.
Pour reinforced concrete and embed foundation bolts/plates. This is the “footing” of the entire system and must guarantee strength.
Step 3: Steel Post & Support Structure Installation
Once the concrete reaches the required strength, install and vertically fix the steel posts.
Install the upper and lower support ropes and tension them to the design specifications, forming the main load-bearing framework.
Step 4: Net Installation & Connection
Unroll the ring nets or wire rope nets panel by panel, securely connecting them to the support ropes and adjacent net panels using shackles and other connectors.
Key Point: Ensure the net panels are flat and taut, and all connection points must be secure and reliable.
Step 5: Final Inspection & Commissioning
Systematically check the tightness of all bolts, shackles, and anchors.
Check that the tension in the nets and support ropes is uniform and meets standards.
Clear the site and prepare for final inspection.
Core Safety Protocols:
Personal Protective Equipment (PPE):
All personnel must wear hard hats, anti – slip gloves, safety boots, and a safety harness for work at height.
Area Isolation:
During installation, hazard zones at the slope toe should be cordoned off with warning lines and monitored by dedicated personnel.
Equipment Inspection:
Hoisting equipment and tensioning tools must be inspected daily before use.
Adherence to Design:
Any design changes or material substitutions not approved by an engineerare strictly prohibited.
