The active protection net does not disrupt or alter the original topography and vegetation growth conditions of the slope, leaving the open characteristics to retain the conditions for implementing artificial slope greening at a later or future time, when conditions are met and necessary.
Key Points for Installing Active Protection Net
The length of anchor rods around the rockfall protection area must be installed at 2 meters during the installation of the active protective net within the rockfall protection zone.
Around the protection area, 2.5-meter-long anchor rods are now being installed to increase the force exerted on the unstable rock by the tension in the horizontal and vertical support ropes, thereby securing the unstable rock and enhancing its overall stability.
To achieve symmetry of the steel rope net at its four corners within the grid formed by the longitudinal and transverse support ropes, we typically use tension hooks.
A hook at one end secures the four corners and midpoints of the steel wire mesh, while the other end hooks onto the corresponding points of the grid formed by the supporting rope. Subsequently, stitching is performed. This method achieves an overall balanced and reasonable distribution of force.
Due to the fact that the active protective nets safeguard unstable rock falls, which are extremely irregular, careful selection of anchor bolt hole layout is essential. Not only does this pose significant construction challenges, but there is also poor fit between the steel rope net and the dangerous rocks.
Several anchor bolt hole placement plans must be formulated at the construction site, and then筛选 out the plans for hole boring to achieve overall load-bearing effects.
