[0033] Working principle of this utility model:

[0034] The steel casing 1 in this structure is a connecting casing of the sandless concrete pipe at the raft position, and is an outer casing for sealing the well. Its height is determined according to the thickness of the foundation raft. The water stop ring 6 is a 60*6mm water stop steel plate ring set on the outside of the steel casing 1. The purpose is to isolate the vertical gap water leakage of the casing side wall. The steel cover plate 3 is used to seal the top of the steel casing 1 after the backfill is completed in the conventional well sealing method, and is welded to the steel casing 1 around it to stop water. In this structure, it also prevents debris from falling into the well during the construction process. The leg 4 is 20m m steel bars are welded to the four corners of the steel cover plate 3, which play the role of erecting the steel cover plate 3 during the construction process, so that there is a 10cm gap between the top of the steel casing 1 and the steel cover plate 3, and the water pump pipe 8 can pass through it. The reinforced support 5 is to connect two 18mm steel bars horizontally at the bottom of the cover plate legs 4 to ensure the rigidity and stability of the four legs 4. The inner support 2 is to weld four 25mm short steel bars around the inner wall of the steel casing 1, the purpose of which is to support the cover plate legs 4 during the construction process and support the steel cover plate 3 when sealing the well;

[0035] During the construction stage, the four legs 4 at the bottom of the steel cover plate 3 correspond to the inner support 2 positions of the inner wall of the steel casing 1, and the steel cover plate 3 is placed to ensure that there is a 10 cm gap between the top of the steel casing 1 and the steel cover plate 3. The water pump pipe 8 can extend out of the precipitation well in this gap and the interval position of the legs 4 to complete the precipitation work. At the same time, this structure can effectively prevent soil particles, stones, construction waste and other debris from falling into the precipitation well during construction, affecting the work of the precipitation well;

[0036] After the construction is completed, when sealing the precipitation well, remove the steel cover 3, pull out the water pump and water pump pipe 8, and after the lower part of the precipitation well is filled, immediately insert the steel cover 3 into the precipitation well. At this time, rotate the steel cover 3 so that the legs 4 at the bottom of the steel cover 3 and the inner support 2 are misaligned with each other, and insert the legs 4 at the bottom of the steel cover 3 into the filling material. The bottom of the steel cover 3 falls on the inner support 2, and the outer edge of the steel cover 3 is welded to the inner wall of the steel casing 1 to form a whole, completing the sealing work.
