The Slope Protection Mesh is a primary technological system for rockfall protection. The Slope Protection Mesh simplifies the structure and foundation form of practical application systems, continuously arranged in units between two steel columns, making it highly adaptable to various complex terrains. To accommodate the industrialization trend in the construction industry, all system components are produced in a standardized factory environment. On-site construction primarily involves modular assembly, with only a small amount of basic construction focused on anchor bolt installation. Construction and maintenance personnel can install, repair, and replace components with minimal conventional simple tools.
The slope protection net effectively utilizes the flexibility and high impact resistance of the material, adapting to various geological disasters on slopes. The main difference from traditional barrier structures lies in the system's flexibility and strength, which are sufficient to absorb and dissipate the kinetic energy of expected falling rocks, effectively transforming the traditional rigid or low-strength, low-flexibility structures into high-strength and flexible ones to achieve the system's protective function.
The slope protection net makes full use of the system's flexibility and the flexibility of construction layout, adapting to various complex terrains and landforms, thus avoiding environmental damage and the harm to the stability of the slope caused by excavation. It takes the comprehensive parameter of the impact kinetic energy of falling rocks as the primary design parameter, avoiding the issue of difficulty in determining the impact dynamic load in traditional structural design, where the load is the primary design parameter. This has achieved quantitative design of the structure and has developed and perfected standardized forms that are capable of adapting to various common types and scales of rockfall.
The slope protection net optimally utilizes the openness of the system to minimize visual disturbances and protect the original vegetation and its growing conditions. It also provides possibilities for green workers to implement greening, fully utilizing the slope-stabilizing effect of plant root systems and the environmental protection and beautification functions of green plants, integrating project management with environmental protection. The development and standardization of the slope protection net products are based on a large number of field tests, and this has resulted in a standardized and balanced design of the system's components. It can safely absorb the kinetic energy of falling rocks within the system's design capabilities and convert it into deformation energy for dissipation. This function is essentially unrelated to the impact point of falling rocks on the net, greatly facilitating the design selection and standardization of the system.
The slope protection net utilizes advanced metal coating technology, employing galvanized steel wire rope and steel or zinc-aluminum alloy coated steel to significantly extend the system's lifespan. In cases of necessity, merely replacing a few components can extend its service life. The design not only considers ease of installation but also ensures feasibility in challenging terrains like cliffs, achieving a quick and simple construction process with minimal anchoring and excavation.
