Active protection systems are various flexible nets, mainly steel wire mesh, that wrap around the required protective slope or rock to limit the weathering, peeling, or destruction of rock and soil on the slope surface, as well as dangerous rock collapse (reinforcement), or to control the movement of falling rocks within a certain range.

Product characteristics: High flexibility, high protective strength, and easy spreading. Adapt to any slope terrain, with standardized and systematic installation procedures. Adopt die cutting installation method, with short construction period and low construction cost. The special manufacturing process of system materials and high anti-corrosion and rust prevention technology determine the ultra-high lifespan of the system. The system can minimize the impact of the engineering team on the environment, and its protective area can fully protect the stability of soil and rock, facilitate artificial greening, and is conducive to environmental protection.

Construction: The first two are fixed by means of steel wire rope pole laying and support rope, while the latter are fixed by means of steel bars (which can be prestressed), steel wire rope anchor rods (which are used when there are edge support ropes), special bedding plates, and edge support ropes.

Passive protection is composed of four main parts: a steel wire mesh, an annular mesh (with a layer of iron wire grille added when intercepting small pieces of falling rock), a fixing system (pole laying, anchor rope pulling, base, and support rope), a pressure relief ring, and a steel column. The connection and combination of steel column and wire rope net form a whole to form a surface protection for the protected area, so as to prevent the falling of collapsed rock and soil mass and play the role of slope protection.

Product characteristics: The flexibility and interception strength of the system are sufficient to absorb and disperse the expected kinetic energy of rockfall impact, and the design and adoption of energy dissipation rings further enhance the system's impact resistance. Compared with rigid interception and masonry retaining walls, the original construction process has been changed, resulting in a reduction in construction period and funds.
