The reasons for high highway slope protection include
and the foundation under the roadbed is an unstable natural sliding body
, The slopes on both sides of the highway are too steep
, The embankment is filled with the wrong method of sloping layers
, The soil is too wet, which reduces the cohesion and internal friction
, Slope Feet were washed by water.
It is caused by the destruction of the stability of individual rock sections after the construction of highways, especially when each rock layer tilts towards the direction of the road cutting and is subsequently damaged by water or earthquakes.
The rock structure and composition of the mountains on both sides of the highway are unstable.
, damage caused by mudslides.
Active Slope Protection Network
Active protection active protection system is based on Various types of flexible nets, mainly wire rope nets, are covered and wrapped on the required protective slopes or rocks to limit the weathering, peeling or damage of rock and soil on the slope and the collapse of dangerous rocks (reinforcement) or to control the movement of rockfall within a certain range (enclosure). protective effect).
Structure
The former two are fixed by wire rope anchors and/or support ropes, and the latter are fixed by steel bars (prestressing can be applied) and/or wire rope anchors (used when there are edge support ropes) ), special anchor pads and edge support ropes and other fixing methods when necessary.
Product Features
High flexibility, high protective strength and easy spreadability. The installation procedure is standardized and systematic to adapt to any slope terrain.
The system adopts die-cut installation method, which has short construction period and low construction cost.
The special manufacturing process of system materials and high anti-corrosion and anti-rust technology determine the ultra-long service life of the system. The system can minimize the impact of the engineering team on the environment. Its protective area can fully protect the stability of soil and rocks, facilitate artificial greening, and is beneficial to environmental protection.
The principle of action is similar to surface slope protection systems such as shotcrete anchors and soil nail walls, but due to its flexible characteristics, the system can distribute local concentrated loads to the surrounding areas. Materials include steel wire mesh and ordinary steel wire grids (often called wire grids). And the high-strength steel wire grating is evenly transmitted to give full play to the protective capability of the entire system, that is, the local load acts as a whole, so that the system can withstand larger loads and reduce the anchoring force requirements of a single anchor rod.
Product Usage
The openness of the system allows groundwater to be discharged freely, which avoids the slope instability problem caused by the increase in groundwater pressure. In addition to making a certain contribution to the stability of the slope, the system also contributes to the stability of the slope. It can also prevent the slope from further weathering and erosion, and there are no special requirements for the morphological characteristics of the slope. It will not destroy or change the original landform and vegetation growth conditions of the slope, and its open characteristics will allow artificial slope greening to be implemented later or in the future when conditions and needs arise. The necessary conditions are retained for green plants to grow freely in the open space. The soil-fixing effect of plant roots is integrated with the slope protection system to inhibit slope damage and soil erosion, which in turn protects the landform and slope vegetation to achieve the best results. Best slope protection and environmental protection purposes.
