The present application belongs to the technical field of sealing well of precipitation well, and discloses a sealing well method of precipitation well, which utilizes a sealing member to isolate the upper and lower well pipes, realizes feeding and filling in the lower well pipe of the sealing member, pressure cement slurry filling in the upper well pipe of the sealing member, and waterproof material is used to strengthen waterproof, and then fine stone concrete or grouting material is poured, and after the sealing plate is closed, a rigid water stop wing ring is arranged inside, and fine stone concrete is poured to form multiple waterproof measures; the sealing member is used to feed and fill the well pipe, which can weaken the effect of groundwater to the greatest extent, and avoids the problems of cement and fine material return caused by groundwater flushing in the prior art. The present application is suitable for sealing well of precipitation well under complex conditions of rich groundwater and high water pressure, and has the advantages of fast sealing well effect, small work load, short cycle, no influence on the surrounding environment, no influence on the safety of underground building structure, flexible and convenient operation, and saved construction period and cost.
