Understanding the Debris flow Protection Nets
This product is a flexible barrier structure, mainly consisting of a tension anchor system, energy dissipation device, steel columns, upper and lower support ropes, anti-sedimentation device, and flexible metal net. It is installed in the gully and is used to intercept the materials carried by debris flows.
Component Description
- Anti-erosion device, 12# channel steel, galvanized layer weight > 600g/m2.
- High-strength steel wire rope, with a diameter of 22 mm, tensile strength > 1770 MPa, minimum breaking force > 284 KN, layer weight > 130 g/m2.
- Circular steel wire mesh: Each ring is formed by winding 7 loops of 0.3mm hot-dip galvanized steel wire. The overlapping length at the ends should be no less than 10cm. It should be evenly distributed at (at least three) locations.

Main construction requirements
- The Debris flow Protection Nets is set according to the gullies on the mountain, and the specific spacing depends on the actual situation on site.
- The anchor rods are marked with instructions. The spacing of the anchoring points can be found in the floor plan of the protection system.
- Both the upper and lower support ropes are arranged in a double-strand configuration. The remaining parts are directly connected to form a whole. The ends of the support ropes are all securely fastened using 6 corresponding rope clamps.
- The ring net is sewn to the upper and lower supporting ropes using corresponding shackles. The seams between the ring nets, between the ring net and the longitudinal rope, and between the ring net and the transverse rope are sewn using sewing ropes or 3.25T shackles.
