AI Technical Summary
During slope excavation in mountainous areas, the scattering of slag and the resulting slag buildup make timely transportation difficult, impacting the ecological environment and encroaching on land acquisition boundaries. Existing technologies are insufficient to effectively prevent slag from flying out of the construction area.
The combination of a detachable composite support frame, an inner elastic barrier net, and an outer rigid slag barrier net consists of several inner elastic barrier nets and an outer rigid slag barrier net. The inner elastic barrier nets use their own elasticity to resist the impact of falling rocks, while the outer rigid slag barrier nets intercept falling rocks, preventing them from flying out of the construction area.
It effectively prevents rocks from being thrown out of the construction area by the muck-hauling aircraft, ensures the safety of vertically intersecting work sections, reduces costs and improves reliability and stability, and saves disassembly and assembly time.
