In recent years, it has been widely used in the stable protection of mountain slopes, the reinforcement and protection of road and bridge construction tunnel openings, the greening protection of scenic mountain slopes, and the weatherproof slope reinforcement and protection of slopes along the roadbed slope. The flexible active protective nets produced by Silop are made of high-quality hot-dip galvanized AB-grade anti-corrosion steel wire ropes and steel wires, which are woven and used with steel rope anchors, support ropes and suture ropes, so as to effectively protect the mountain from collapse and plant grass and green on this basis, which can not only purify the air and beautify the environment, but also prevent soil erosion, weathering of soil and rock slopes.
Slope mountain weatherproof active protection flexible net, active protection net, is a flexible protective net that has been gradually widely used in recent years, can be used in highways, railways along the slope slope, tunnel mouth slope, scenic mountain, natural village slope mountain protection, etc. This system can effectively stabilize the slope of the mountain, and this system can use the plant root system of the system to combine with the active protection system, so as to restore the ecological environment, consolidate the stability of the slope, promote the degradation of organic pollution, purify the atmosphere, prevent and reduce natural disasters such as landslides and dangerous rock collapses.
The ultimate purpose of slope geological disaster prevention and control is to prevent the injury of disaster materials and the loss of various property, that is to say, the purpose of prevention and control is not necessarily to prevent the occurrence of natural phenomena such as disasters, but to prevent the corresponding harm caused by disasters on the day of disasters. Therefore, the prevention and control idea can be considered from two aspects: preventing disasters and avoiding harm. Based on this guiding ideology, the SNS protection system distinguishes different protection principles and protection purposes, and can be divided into three categories: slope stabilization system, enclosure system and rockfall interception system.
When the slope mountain weatherproof active protection flexible net is installed, the support rope is crossed vertically and horizontally, penetrates in the anchor hole below the ground surface, and is tightly attached to the slope surface after tensioning, forming a wave-shaped force transmission system. When the protection of dangerous rock movement or has a movement trend, the protective net on a certain protective cell in the system can be subjected to the load cutting pointing to the slope surface, this force is transmitted to the support rope and the anchor rod of the four corners through the suture rope, the anchor rod transmits a part of the force to the rock and soil mass, and the other part of the force acts on the support rope to make it pull and tighten, so that the support rope on both sides of the protection cell then produces a linear motion trend, these support rope segments are constrained by a plurality of anchors, thus a mechanical balance system can be formed at each anchor rod, and the tensile force that the support rope is subjected to is partially decomposed and transmitted to the rock and soil mass through the anchor rod; And the support rope is tensioned in advance and close to the slope surface during installation, and any movement of the support rope will be subjected to the huge friction force from the surface, so that the load generated by the movement of the dangerous rock mass forms a new mechanical balance with the surrounding bolt pull-out force and the friction force that the support rope receives, so as to achieve a stable state. In addition, because the system adopts a flexible anchor, the flexible anchor head can be disposed of in a certain space around the mortar anchorage point in a certain space after being stressed, and the connection between the support rope and the anchor head adopts the mode of wearing the sleeve, and the support rope can effectively slide in any anchor sleeve, so that it is conducive to mobilizing other bolts to participate in the force through the tensioning of the support rope, and effectively avoids the stress concentration at the anchor head, reduces the stress of the anchor around the dangerous rock, thereby realizes the apportionment of the load, and achieves the "local force, overall effect" effect.
The vertical root system of the plants of the slope protection net can pass through the loose weathering layer of the shallow layer of the slope and anchor to the more stable rock and soil layer at depth, which plays the role of prestressed anchor. Grasses, legumes and small shrubs are 07~1.5m has a significant soil strengthening effect, and the anchoring effect of the tree root system can affect the deeper underground rock and soil layers. The shallow-rooted herbaceous plants, their roots are intertwined in the soil, so that the slope soil becomes a composite material of soil and grass roots, and the grass roots are like three-dimensional reinforced materials with prestress, which greatly improves the strength of the soil. The instability of the slope is closely related to the water pressure of the slope, and rainfall is one of the important factors that induce gravity erosion. By absorbing and transpiring the water in the slope, the plant can reduce the pore water pressure of the soil, improve the shear strength of the soil, and then promote the stability of the slope. On the slope with vegetation cover, the rainfall is intercepted by the vegetation before it reaches the slope surface, and the vegetation stems and leaves have an obvious pin energy effect on the raindrops and concentrated streams, which can effectively prevent the water erosion of the slope surface. Vegetation cover is also effective in preventing wind-blown sand disasters.
The flexible characteristics of the slope mountain weatherproof active protection flexible net, SNS active protection net (active net, active protection net, slope protection net) can enable the system to evenly transmit the local concentrated load to the surroundings to give full play to the protection ability of the whole system, that is, the local load, the overall effect, so that the system can bear a large load and reduce the anchoring force requirements of a single anchor. In addition, due to the openness of the system, groundwater can be discharged freely, avoiding slope instability caused by the increase in groundwater pressureIn addition to stabilizing the slope, the active protection net can also inhibit the slope from further weathering and denudation, and there is no special requirement for the slope morphological characteristics, and does not destroy and change the original landform and vegetation growth conditions of the slope, and its open characteristics retain the necessary conditions for the subsequent or future conditions and when necessary to implement artificial slope greening, green plants can grow freely in its open space, and the soil fixing effect of plant roots is integrated with the slope protection system, so as to inhibit slope damage and soil erosion
Slope mountain weatherproof active protection flexible net, Silop not only produces active and passive protection nets, equipped with professional construction personnel and advanced machinery and equipment, to undertake slope protection and greening projects across the country, perennial with common specifications and models of active protection nets passive protection nets in the spot, long-term cooperation with China Railway, China Construction, hydropower and water conservancy, road and bridge construction and other companies, and has been trusted by new and old customers. The common models of active slope protection net are GPS1 type, GPS2 type, GTC-65A type, the user needs to choose the model configuration according to the actual conditions of the mountain slope that needs to be protected, in general, the configuration drawings of the flexible active protective net are issued by the professional design institute, the protective network is customized according to the drawings and specifications provided by the customer, if the user does not have drawings, the active network of the corresponding specifications and models can be recommended according to the production and construction experience of many years and the specific situation of the field investigation。
