Active protection net introduction: The active protection net system is covered with various types of flexible nets mainly made of steel wire rope nets and wrapped on the required protective slopes or rocks, so as to limit the weathering, peeling or damage of rocky soil on the slope surface and the collapse of dangerous rocks (reinforcement effect) ), or control the movement of falling rocks within a certain range (containment effect). The active protection net is a protection technology for dangerous rocks and falling rocks. The advantages of the active protection net are short construction period, strong adaptability to the terrain, relatively sensitive construction and installation, and the active protection net can be installed in any required position on the slope. Active protection The net can withstand the influence of bad weather. The active protection net makes full use of the easy spreadability and high impact resistance of flexible materials. Through this system and a large number of on-site tests, a geological disaster protection technology suitable for various slopes and natural slopes has been formed, so as to facilitate engineering quality control and Accurate measurement of engineering quantities. The active protective net makes full use of the lightweight and easy-to-process characteristics of high-strength metal materials to achieve the intention of lightweight. The construction period of the active protective net is short. Moreover, the installation and maintenance are simple, and it handles the complex terrain conditions in mountainous areas. Traditional protection methods Problems that are difficult to deal with for a long time. The openness of the active protective net use system allows the groundwater to drain freely, avoiding the problem of slope instability caused by the increase of groundwater pressure; the system not only contributes to the stability of the slope, but also inhibits the slope from being damaged. Further weathering and denudation, and there is no special requirement on the slope surface features, without destroying or changing the original landform and vegetation growth conditions on the slope surface, and its open features are necessary for the subsequent or future artificial slope greening when conditions and needs are met. Green plants can grow freely in its open space, and the soil-fixing effect of plant roots is integrated with the slope protection system, thereby inhibiting slope damage and soil erosion, which in turn protects the landform and slope vegetation. Realize the purpose of slope protection and environmental protection.
