Plugging structure of dewatering well for high-pressure-bearing water-rich stratum

The utility model discloses a dewatering well plugging structure for a high-pressure-bearing water-rich stratum, which is characterized by comprising a plugging pipe connected with a well mouth of a dewatering well, a water stop ring annularly sleeved on the outer wall of the plugging pipe, a plugging cover, rotary support pieces symmetrically arranged on the inner wall of the plugging pipe, and a rotary shaft with two ends rotatably connected with the rotary support pieces, and a plugging ring. The method not only can solve the problems of high water inflow of the high-pressure-bearing water-rich stratum precipitation well and plugging of the precipitation well under the condition of high pressure-bearing water head after the construction of the main body structure is completed, but also can prevent and cope with the blockage of the precipitation well during the construction precipitation period of the main body structure. And the construction of a main body structure is influenced by a large amount of gushi
