Under-pressure plugging device and plugging method for gas leakage of underwater pipe gallery
The invention relates to an under-pressure plugging device for gas leakage of an underwater pipe gallery. The under-pressure plugging device comprises the underwater pipe gallery and a leakage channel, wherein a base is arranged in the underwater pipe gallery in the diagonal position of the leakage channel, and a jacking device is arranged on the base; a sleeve is arranged on the jacking device and is in threaded connection with a pressing rod piece; and the top end of the pressing rod piece is in threaded connection with an arc-shaped supporting plate, a flexible blocking plate is bonded to the supporting plate, a blocking strip is arranged on the edge of the blocking plate and surrounds the peripheral side of the leakage channel, and the peripheral side of the supporting plate is connected with the underwater pipe gallery through bolts. The invention further relates to an under-pressure plugging method for gas leakage of the underwater pipe gallery, which is used for the under-pressure plugging device for gas leakage of the underwater pipe gallery. According to the under-pressure plugging device, the jacking device is matched with the pressing rod piece to temporarily block the leakage channel, expansion bolts are connected with the supporting plate and an upper pipe piece, the leakage channel can be permanently blocked, blocking construction is convenient and fast, the blocking structure is stable, and rapid emergency treatment can be conducted on gas leakage of the pipe gallery.
本发明涉及用于水下管廊气体泄漏的带压封堵装置，包括水下管廊以及渗漏通道，渗漏通道对角位置的水下管廊内布设有底座，底座上设置有顶举设备；顶举设备上设置有套筒，套筒螺纹连接有压杆件；压杆件顶端螺纹连接有弧形撑板，撑板上粘接有柔性封堵板，封堵板边缘处设置有堵条，所述堵条围设在渗漏通道周侧，所述撑板周侧与水下管廊螺栓连接。本发明还涉及用于水下管廊气体泄漏的带压封堵装置的水下管廊气体泄漏带压封堵方法。本发明通过顶举设备配合压杆件可对渗漏通道进行临时封堵，膨胀螺栓连接撑板与上管片，可对渗漏通道进行永久封堵，封堵施工便捷，封堵结构稳固，可对管廊气体泄漏快速应急处治。
