Flexible protection device for weakening underwater explosion shock wave load
The invention belongs to the technical field of engineering safety, and discloses a flexible protection device for weakening an underwater explosion shock wave load. The flexible protection device for weakening the underwater explosion shock wave load is provided with a floating cylinder capable of floating in water; the floating cylinder is wound with bubble films; the bubble films are wound on the floating cylinder by multiple layers; the bubble film on the innermost layer is fixedly connected with the floating cylinder; the end of the bubble film on the innermost layer is connected with a counterweight clamping plate; and the bubble films are arranged in vertical water by using the gravity of the counterweight clamping plate and the buoyancy of the floating cylinder in water, and form an air separation layer for attenuating underwater explosion shock waves. The flexible protection device can protect surrounding structures during underwater blasting removal, and reduces the damage of such structures as high-pile wharfs, caisson wharfs, cross-sea bridges and river-crossing tunnels in water under accidental or intentional explosion loads.
本发明属于工程安全技术领域，公开一种用于削弱水中爆炸冲击波载荷的柔性防护装置。公开的一种用于削弱水中爆炸冲击波载荷的柔性防护装置具有可在水中漂浮的漂浮圆筒；所述的漂浮圆筒上缠绕有气泡膜；所述的气泡膜为缠绕在漂浮圆筒的多层，且最内层所述的气泡膜与所述的漂浮圆筒固联；最内层所述气泡膜的端头连接有配重夹板；多层所述的气泡膜在水中利用的配重夹板重力与漂浮圆筒的浮力设置在竖直水中，并形成用以对水中爆炸冲击波进行衰减的空气隔层。本发明可对水下爆破拆除时的周围结构进行防护，以及降低高桩码头、沉箱码头、跨海大桥、过江隧道等结构的水中构件，在意外或蓄意爆炸载荷下的损伤破坏。
