Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] refer to Figure 1 to Figure 4 , a combined structure for resisting high-energy rockfall on steep slopes according to the present invention, resisting units are arranged laterally at intervals on the steep slope below the rockfall running track, and a plurality of resisting units are combined to form a structural system for resisting high-energy rockfall. The resistance unit includes at least two wedge-shaped support piles 10 spaced apart, the lower part of each wedge-shaped support pile 10 is anchored in the stable rock and soil layer under the steep slope, and the upper part of the exposed slope has an oblique cut surface on the side of the mountain 11. Long-distance restorable energy-absorbing devices 20 are arranged at intervals on the beveled surface 11, and rigid bearing plates 30 are arranged between the wedge-shaped support piles 10 on bo...

Abstract

The invention discloses a combined structure for resisting steep slope high-energy rockfall, and aims to realize effective prevention, control and treatment of high-position and large-volume dangerousrocks in complex hard mountainous areas. Resistance units are transversely arranged on an abrupt slope below a rockfall moving track at intervals, and the multiple resistance units are combined to form a high-energy rockfall resistance structure system. Each resisting unit comprises at least two wedge-shaped supporting piles which are arranged at intervals. The lower part of each wedge-shaped supporting pile is anchored into a stable rock-soil layer below the slope surface of the abrupt slope; a diagonal plane is arranged on the side, close to the mountain, of the upper portion of an exposedslope, long-range recoverable energy absorption devices are arranged on the diagonal plane at intervals, a rigid bearing plate is arranged between wedge-shaped supporting piles on the two sides, the rigid bearing plate is fixedly connected with the long-range recoverable energy absorption devices behind a plate body, and an elastic buffer body is fixedly arranged on the front plate face of the rigid bearing plate.

Description

technical field [0001] The invention relates to civil engineering, in particular to a combined structure resistant to high-energy falling rocks on steep slopes, which is suitable for the prevention and control of high-position and large-volume dangerous rocks in complex and dangerous mountainous areas. Background technique [0002] Due to the steep terrain and strong tectonic activities in complex and dangerous mountainous areas, a large number of high-level and huge dangerous rock masses have been formed. Under the action of earthquake, long-term rainfall or heavy rain, they are easy to roll down along the steep slope, forming a high potential energy impact force far exceeding 5000KJ. Impact, burial and other hazards to downstream facilities. At present, the maximum energy level of domestic conventional passive protection nets for steep slopes is 3500KJ, which cannot meet the requirements for the prevention and control of such high-level and large-volume steep slopes. Con...
