Introduction of active protective net: The active protective net system is a kind of flexible net mainly composed of steel wire rope net, which covers and wraps on the required protective slope or rock to limit the weathering, spalling or destruction of rock and soil on the slope and the collapse of dangerous rock (reinforcement function) or control the falling rock to move within a certain range (enclosure function)

The open groundwater of the active protective net system can be discharged freely to avoid the slope instability caused by the increase of groundwater pressure; The system not only contributes to the stability of slope, but also can restrain the slope from further weathering and denudation, and has no special requirements for the slope morphological characteristics, does not destroy or change the original landform and vegetation growth conditions, and its open characteristics reserve the necessary conditions for the implementation of artificial slope greening later or when conditions are available and necessary in the future. Green plants can grow freely in their open space, and the soil fixation of plant roots is integrated with the slope protection system, thus inhibiting slope damage and soil erosion, and in turn protecting landform and slope vegetation to achieve the purpose of slope protection and environmental protection

Active protective net is more and more widely used in slope treatment. Now many highway slope treatments think it is suitable to use active protective system. Active protective net has high maintenance strength, high elasticity, easy dispersion, and is suitable for any slope topography. Standardization and systematization of device program

Active protective net system is suitable for using die-cutting device, with short construction period and low cost The special manufacturing skills of active protective net system materials and high anti-corrosion and anti-rust skills can fully consider the stability of soil and extruded rock, which is easy to be artificially beautified and beneficial to environmental maintenance

Active protective net makes full use of the lightweight and easy-to-process characteristics of high-strength metal materials to achieve lightweight intention of active protective net construction cycle. It is short and simple to install and maintain, which solves the problem that the traditional protection method is difficult to deal with for a long time under the complex terrain conditions in mountainous areas

Make full use of the sensitivity of active protective net and the sensitivity of construction layout to adapt to various complex environments to a great extent. Make full use of the openness of slope protective net system to protect the original vegetation and its growth conditions and combine project management with environmental transformation
