[0002] Currently, underground construction in low-lying areas with abundant groundwater requires the use of deep foundation pit dewatering wells, which must then be sealed. Because the water pressure in these wells is high and the water level rises rapidly, rapid sealing of these wells is crucial. Traditional methods of sealing these wells suffer from lengthy construction times, high costs, and disruptions to project performance.

[0003] In actual use, the existing structure is an integrally formed structure of the well casing, outer water stop ring, inner water stop ring and well cover base. When the water stop plate and well cover are subsequently installed, they need to be inserted from the upper end of the well casing and then sealed and installed. Since such a structure is not provided with a positioning device, it takes some time to position it during installation. Improper positioning may result in poor sealing effect. If the positioning time is long, groundwater may seep out, resulting in sealing failure. For this reason, a rapid sealing device for deep foundation pit dewatering wells is proposed.
