Large-scale tunnel plugging device
The invention belongs to the technical field of tunnel plugging, and particularly relates to a large-scale tunnel plugging device which comprises a rigid inner core, an elastic bag, a first electromagnetic switch valve, a second electromagnetic switch valve, a pump and a third electromagnetic switch valve, the rigid inner core is integrally in a bowl shape or a cup shape, an opening faces the upstream of a tunnel, namely the high-pressure side, and the rigid inner core is mainly used for reducing the weight of the whole body; the rigid inner core comprises a plurality of cabins, the cabins are in a centrosymmetric grid shape and distributed in the circumferential direction, and the cabins are divided into closed water cabins, water passing cabins and dry cabins. According to the device, the bowl-shaped or cup-shaped rigid inner core is adopted, cabins of various specifications and functions are arranged in the inner core, the overall weight is reduced, and the posture of the device in water can be adjusted easily; the corrugated variable-diameter hollow elastomer bag is designed, the shearing force of the elastic bag is effectively reduced, in combination with the design of a hydraulic loop, the large-scale tunnel can enter and exit, and the technical problem that plugging operation cannot be executed on the large-scale tunnel at present is solved.
本申请属于隧道封堵技术领域，尤其是涉及一种大尺度隧道封堵装置，包括刚性内核、弹性囊、第一电磁开关阀、第二电磁开关阀、泵和第三电磁开关阀，所述刚性内核整体呈碗型或杯型，开口朝向隧洞上游，即高压侧，主要作用是减轻整体的重量，所述刚性内核包括多个舱室，舱室呈中心对称的网格状，沿周向分布，所述舱室划分为密闭水舱、通水舱及干舱。本发明中，采用了碗型或杯型的刚性内核，内部设置多种规格和功能的舱室，降低了整体重量，有利于调节装置在水中的姿态；设计了波纹状变径的中空弹性体囊，有效降低了弹性囊的剪切力，结合液压回路的设计，实现了出入大尺度隧洞，解决了目前大尺度隧洞无法执行封堵作业的技术难点。
