Variable section type tunnel plugging device
The invention belongs to the technical field of water conservancy projects, and particularly discloses a variable-section tunnel plugging device. The variable-section tunnel plugging device comprises a supporting assembly and a plugging assembly. The supporting assembly comprises a supporting shaft, a first supporting part, a second supporting part and a third supporting part, the plugging assembly comprises a first plugging piece, a second plugging piece and a third plugging piece which are sequentially connected in the axial direction of the supporting shaft, the first plugging piece is arranged outside the first supporting component and is in a conical cylinder shape, and the end, away from the second plugging piece, of the first plugging piece is connected with the supporting shaft and sealed. The second plugging piece is arranged outside the second supporting component, the section shape of the second plugging piece is a first ring matched with the section shape of the first section, and the section shape of the third plugging piece is a second ring matched with the section shape of the second section. The tunnel plugging device can plug tunnels with different sections, the safety of tunnel plugging is improved, and the construction period is shortened.
本发明属于水利工程技术领域，具体公开了一种变断面型隧洞封堵装置。变断面型隧洞封堵装置包括支撑组件和封堵组件，支撑组件包括支撑轴和依次设置于支撑轴的第一支撑部件、第二支撑部件和第三支撑部件。封堵组件包括沿支撑轴的轴向依次相连的第一封堵件、第二封堵件和第三封堵件，第一封堵件设置于第一支撑部件的外部，第一封堵件呈锥筒形，且第一封堵件的背离第二封堵件的一端与支撑轴相连并封闭，第二封堵件设置于第二支撑部件的外部，第二封堵件的断面形状为与第一段的断面形状相匹配的第一环形，第三封堵件的断面形状为与第二段的断面形状相匹配的第二环形。本发明能够对不同断面的隧洞进行封堵，提高对隧洞封堵的安全性，降低施工周期。
