Description

Multi-adaptability spliced fixed organic fiber protection net sheet Technical Field The invention belongs to the technical field of protection engineering, and particularly relates to a multi-adaptability spliced fixed organic fiber protection net sheet. Background Traditional flexible protective nets (such as slope protection SNS systems) rely on steel rope nets/annular nets to 'passively bear' to intercept falling rocks, and the strength and energy consumption of a focusing structure are designed. But the problems of heavy weight, stiff deployment, poor corrosion resistance, poor maneuverability, lack of real-time perception and intelligent response are exposed to threat diversification (small-sized rapid unmanned aerial vehicle) and scene complicacy (temporary deployment of urban security). The traditional flexible protective net adopts a single-layer steel rope net or an annular net to intercept falling rocks in a passive bearing mode, and the design core only focuses on single structural strength and basic energy consumption. However, the traditional protective net has a plurality of defects that a single-layer structure is difficult to simultaneously cope with high-speed impact and energy buffering and the edge of the net surface is easy to tear due to stress concentration when facing to diversified threats (such as high-speed collision of an unmanned aerial vehicle, explosion shock waves and explosion fragments) and complicated scenes (such as high-altitude falling objects of a building and temporary military area protection).
