Q235 material GPS2 active protective net for landslide rockfall slope reinforcement

Description :

  GPS2 active protection net is a slope treatment product with high-strength steel wire rope flexible protection system as the core, mainly solving the safety threats of landslides, collapses, and rockfalls to the roads, buildings, or personnel below. The system is installed in a covered manner to fix potential unstable rock masses on the slope, utilizing its high flexibility and strength to absorb and disperse impact energy. Typical working conditions include steep rock slopes, easily weathered and fragmented mountains, and both sides of traffic arteries with sporadic rockfall risks. As the mainstream selection in slope protection engineering, GPS2 active protection net can effectively limit the deformation of surrounding rock, prevent disasters caused by shallow surface damage, and is suitable for various mountainous environments with complex geological conditions, ensuring the long-term stable operation of infrastructure.

  The main material of GPS2 active protective net is usually made of Q235 steel wire rope net and support rope, which has excellent tensile strength and corrosion resistance. In standard configuration, the diameter of the wire rope mesh is generally 300mm × 300mm or 400mm × 400mm, with a wire diameter of 8mm or more, used in conjunction with boundary support ropes with diameters of 16mm-20mm and suture ropes with diameters of 12mm-16mm. Surface treatment processes often use hot-dip galvanizing or zinc aluminum alloy coatings, and some high-end requirements can add PVC protective layers to enhance weather resistance in harsh climates such as humidity and acid rain. The implementation standard refers to TB/T 3089-2004 "Design Specification for Railway Roadbed Support Structure" and relevant technical guidelines for slope protection engineering, ensuring that every meter of GPS2 active protection net can withstand the specified kinetic energy impact test, meeting the strict quality requirements of the country for geological disaster prevention and control engineering.

  In the selection stage, it is necessary to clearly distinguish between the application scenarios of active protection and passive protection. GPS2 active protective net is suitable for areas with relatively intact slopes and main risks from loose rock blocks or small landslides on the surface, emphasizing "reinforcement" and "restraint"; If there is a risk of large-scale collapse or significant displacement of the slope, rigid support measures such as anchor rod frame beams should be combined, or passive interception nets should be used for bottom protection. When purchasing GPS2 active protective nets, it is important to check the breaking force of the steel wire rope, the matching size of the mesh, and the material grade of accessories such as buckles and shackles. For highly corrosive high-altitude or coastal areas, it is recommended to prioritize the selection of high anti-corrosion coating specifications to avoid high maintenance costs in the later stage and ensure the reliability of the protective system throughout its entire life cycle.

  The installation of GPS2 active protective net requires strict construction process flow. Firstly, slope cleaning is carried out to remove floating stones and vegetation, and then the anchor bolt hole position is determined by measuring and setting out. The drilling depth is usually not less than 2.5 meters, and after injecting cement mortar, anchor rods are inserted and support ropes are fixed. During the process of hanging the net, it is necessary to ensure that the overlap width between the net pieces is not less than 10cm, and to tightly connect them with sewing ropes to ensure uniform overall force distribution. In daily maintenance, it is necessary to regularly inspect the slope for any new cracks, deformation or corrosion of the mesh, and looseness of the anchor head. Once local damage is found, the damaged mesh should be repaired or replaced in a timely manner to prevent the disease from expanding. Proper installation and regular maintenance are key factors in extending the service life of GPS2 active protective net and ensuring the effectiveness of slope protection.
