Description

Technical Field

[0001] This invention relates to the field of slope rock mass protection technology, and in particular to a prevention and control structure for dangerous rock masses on steep slopes. Background Technology

[0002] Unstable rock masses refer to rock formations that have not yet collapsed but show signs of imminent collapse. While their surface may appear stable, they actually contain numerous dangerous factors. If left untreated, a collapse would cause serious safety accidents, especially on steep slopes where the resistance to collapse is relatively small, leading to more severe damage. Therefore, during construction on steep slopes, it is crucial to prioritize the treatment of unstable rock masses to prevent collapse and ensure construction safety ("Discussion on Construction Technology for the Treatment of Unstable Rock Masses on Steep Slopes," Zhang Zhengyong, 2016).

[0003] Since unstable rock masses are primarily prone to toppling damage, their treatment should focus on preventing this damage. When managing unstable rock masses, it's crucial to avoid excessive disturbance (such as large-scale blasting) to prevent further damage to the mountain. Scholars like Cheng Kang proposed a flexible network locking method, which involves an anchor-pulled shotcrete locking system. This system uses vertical prestressed anchors to reinforce the rock columns, then interlocks these columns with prestressed inclined steel strands and a steel mesh to form a unified structure. Finally, shotcrete is applied to create a weather-resistant, closed, strong zone on the surface. This transforms the original statically determinate rock mass structure into a statically indeterminate one. This system possesses a degree of flexibility, allowing for moderate deformation of the rock mass. When deformation pressure acts near the locking zone, the stress is appropriately released, preventing excessive expansion of the plastic zone and preserving the original strength of the rock mass. This fully utilizes the rock mass's self-supporting capacity, allowing the rock mass and the locking system to jointly bear the forces exerted by the mountain.

[0004] However, the treatment of unstable rock formations is a highly targeted engineering measure, as the situation of each individual unstable rock is different, and the corresponding treatment plan will also vary. This necessitates the standardization of the safety factor for unstable rock formations and the stability assessment of the potential hazards of unstable rocks, providing practical and feasible operating procedures for unstable rock formation treatment.

[0005] For example, the design and application of material lifting frames in the prevention and control of unstable rock masses, proposed by Cheng Wenming et al., played a crucial role in vertical transportation under the special environmental conditions of the Lianziya unstable rock mass prevention and control project in the Three Gorges of the Yangtze River. Similarly, in the prevention and control of the Lianziya unstable rock mass in the Three Gorges of the Yangtze River, the anchored drilling technology proposed by Wang Yanshu et al. provided solutions to technical problems such as drilling rig positioning in cliff construction, prevention of borehole deviation and inclination measurement in complex strata, and drilling and plugging methods in fractured zones and large cracks.

[0006] Therefore, the prevention and control of unstable rock masses is a systematic approach that includes the identification, monitoring, removal, and reinforcement of unstable rock masses. The ultimate goal is to avoid or reduce the adverse consequences of unstable rock mass collapse on the safety of engineering projects or residents.

[0007] In the prior art, the invention patent (CN114438913A) of Shaanxi Nuclear Industry Engineering Survey and Design Institute Co., Ltd. discloses a collapse prevention device suitable for unstable rock masses on slopes. The device includes a base, a lifting component, a stabilizing component, and four telescopic rods. The bottom of the lifting component is welded to the top of the base. A sliding plate, which is rectangular in shape, is movably connected to one side of the lifting component. The bottom of the stabilizing component is welded to the middle end of the top of the sliding plate. The bottoms of the four telescopic rods are welded to the four corners of the sliding plate. By adjusting the height of the four screws and the stabilizing component, the four telescopic rods can be used to perform collapse prevention operations on rock masses of different sizes, making the device more adaptable. Anti-slip pads are provided on the top of the screws to increase the friction between the screws and the rock mass, ensuring a more reliable stabilization of the screws. The stabilizing component and the four telescopic rods ensure thorough contact between the device and the rock mass surface, making the device more robust in preventing rock collapses.

[0008] However, many existing protective measures cannot adjust the protection range of rock masses, are inconvenient to use, and current rockfall prevention structures typically use protective nets to block falling rocks. These structures are simplistic and ineffective in protecting pedestrians and equipment below, resulting in low safety performance. Technological innovation in rockfall prevention still requires significant effort from those skilled in the art. Summary of the Invention
