Plugging system and plugging method suitable for deeply-buried pipeline
The plugging system comprises a rigid lowering device and a plugging air bag, a rotary connecting rod is arranged at the lower end of the rigid lowering device, the length of the rotary connecting rod is larger than the radius of an inspection well, and when the end of the rotary connecting rod is lowered to the rear portion of the inspection well or close to the well bottom, the plugging air bag can be plugged into the rigid lowering device. Upward rotation is performed until the end part enters a blocked pipeline; a pneumatic telescopic arm is arranged on the rotating connecting rod, the plugging air bag is fixed on the pneumatic telescopic arm, and after the end part of the rotating connecting rod is rotated into the plugging pipeline, when the pipeline needs to be plugged, the pneumatic telescopic arm is extended, and the plugging air bag is fed into the plugging pipeline. Unmanned well-descending plugging can be achieved for the deeply-buried pipeline, an operator only needs to operate plugging equipment above an inspection well, the safety risk is effectively reduced, and the method can be suitable for the high-water-level operation working condition of a sewage pipe network system.
本发明公开了一种适用深埋管道的封堵系统及封堵方法，该封堵系统包括刚性下放装置和封堵气囊，所述刚性下放装置的下端设置转动连杆，所述转动连杆的长度大于检查井的半径，而能在其端部下放到检查井底后或接近井底时，向上转动至其端部进入被封堵管道中；在所述转动连杆上设置气动伸缩臂，所述封堵气囊固定在气动伸缩臂上，而在转动连杆的端部转入所述封堵管道后，在需封堵管道时，伸长气动伸缩臂，将封堵气囊送入封堵管道内部。本发明针对深埋管道可能够实现无人下井封堵，操作人员只需在检查井上方即操作封堵设备，有效降低安全风险，并且可适用污水管网系统的高水位运行工况。
