Product Application
It is mainly applied to steep rocky slopes of open-pit mines, high-risk cliff scenic areas, steep banks of large water conservancy hubs, and high-risk cutting sections of mountain trunk roads. For protection scenarios with huge single falling rock mass, full-scale physical rock drop impact tests can be conducted separately to satisfy mandatory geological hazard control requirements of key transportation, mining and water conservancy projects. The installed system will not interfere with subsequent slope geological monitoring and rock reinforcement construction.
Customization Service
1.The quantity of energy dissipation rings per span can be adjusted according to the maximum rock weight and vertical fall height on site to raise the overall energy absorption limit.
2.Two high-end anti-corrosion options including zinc-aluminum-magnesium alloy coating and full 304 stainless steel are available for mining areas with long-term humidity and heavy acid rain.
3.Full sets of test reports with official qualification seals and original impact test data can be supplied as required to meet document review standards for government tenders.
4.The wall thickness of steel posts and anchoring depth of anchor bolts can be customized by thickening or deepening based on rock hardness and landslide risk grade of mountain slopes.
FAQ
Q: Can complete qualified test of Rockfall Barriers be provided for project bidding?
A: We can supply stamped national standard inspection reports, original full-scale rock impact test data and salt spray & tensile test records. All documents are traceable and meet the bidding review standards of key mining, water conservancy and highway projects.
Q: How to extend anti-corrosion service life of Rockfall Barriers for mines with heavy acid rain and high humidity?
A: Customized zinc-aluminum-magnesium alloy coating or full 304 stainless steel components are optional. Zinc-aluminum-magnesium coating provides far better rust resistance than ordinary hot-dip galvanization for long-term humid mining environments.
Q: How to improve energy absorption capacity if the rock mass exceeds standard weight?
A: We can increase the number of energy dissipation rings per span, thicken steel posts and deepen anchor bolt depth. Custom high-energy protection solutions are designed according to rock fall height and rock weight.
