The invention relates to a method for quick recovery of vertical water stoppage of a water gate. The method for quick recovery of vertical water stoppage of the water gate comprises the following steps that (1) a hole position is set; (2) a hole is drilled in a junction, and the drilled hole and a grouting hole are sealed; (3) water-swelling waterstops are installed; (4) a water injection test is conducted; (5) a grouting pipe is installed; (6) water in the holes are drained; (7) an exhaust pipe or a water draining pipe is placed downwards; (8) the surface is sealed along a seam; and (9) grout preparation, grouting and grout sealing are conducted, and the whole process is ended. According to the method for quick recovery of vertical water stoppage of the water gate, the loss of grout can be prevented, and the grouting quality is guaranteed; the round water-swelling rubber waterstops provided with inner pipes are arranged on the two sides to stop grout, a hole-sealed pure-pressure grouting way is used for grouting, and grouting materials are flexible polyurethane materials so that water can be stopped, and the tensile deformation resistance is achieved; the device is simple, and the structure is simple and low in cost; and compared with other treatment methods, operation is convenient, faster and economical.
