The cylinder is the main part of the tank truck which is damaged. Aiming at the barrel leakage accident of the tank truck with the pressure tank, a fireman generally adopts a binding type plugging tool to carry out emergency plugging. The binding type plugging tool mainly comprises a plugging block (or a plugging module), a rope (a steel wire rope and a binding belt), a rope tensioning-locking device, a power source and accessories thereof and the like, and the using method comprises the following steps: firstly, the plugging block is tightly pressed on a leakage part; secondly, binding a rope to the barrel, wherein one end of the rope is placed in a groove on the outer side of the leakage blocking sheet, and the other end of the rope is arranged on a rope tensioning-locking device; secondly, connecting the power source and accessories thereof with the rope tightening-locking device, and then driving the power source to tighten the rope until the leakage is avoided; finally, the harness cord-lock is operated to define the position of the harness and the power source and its accessories are removed.
