Fabricated bulletproof and anti-explosion device suitable for entrance and exit of subway station
The invention relates to an assembly type bulletproof and anti-explosion device suitable for a subway station entrance and exit. The assembly type bulletproof and anti-explosion device comprises an embedded sleeve, a sleeve end plate, an embedded part stiffening rib, a prefabricated steel pipe stand column, an arc-shaped wall panel, a wall panel connecting piece, a rotating pulley, a handle and an arc-shaped porous filling building block. The device is divided into an overground part and an underground part, the overground part is formed by welding an embedded sleeve, a sleeve end plate and an embedded part stiffening rib, an upper prefabricated steel pipe stand column can be directly inserted into the embedded sleeve, a plurality of arc-shaped wall panels are connected through connecting pieces to form an assembly wall face capable of being freely folded and unfolded, and the middle of the assembly wall face can be filled with arc-shaped porous filling building blocks; the device can change the motion trail of the projectile body, the distance from the explosion center to the subway station entrance and exit is remarkably increased, the curved surface structure can accelerate dissipation of explosion shock waves, and damage of explosion loads to the subway station entrance and exit is weakened. The device is simple in structural design, low in manufacturing cost, capable of achieving assembly type construction, high in maneuverability and good in applicability.
本发明是一种适用于地铁站进出站口的装配式防弹抗爆装置，包括预埋套筒、套筒端板、预埋件加劲肋、预制钢管立柱、弧形墙面板、墙面板连接件、转动滑轮、把手、弧形多孔填充砌块；该装置分地上和地下两部分，地上部分由预埋套筒、套筒端板和预埋件加劲肋焊接而成，上部预制钢管立柱可直接插入预埋套筒内部，多页弧形墙面板通过连接件连接形成可自由折叠和展开的装配墙面，中间可填充弧形多孔填充砌块；本发明装置可改变弹体运动轨迹，显著增大爆心至地铁站进出站口的距离，曲面结构可加快爆炸冲击波消散，削弱爆炸荷载对地铁站进出站口的毁伤破坏。该装置结构设计简单，制作成本低，可装配式施工，机动性强，应用性好。
