| description | The invention relates to the field of civil engineering, in particular to a whirling well cone-bottom sealing method and an application thereof. The bottom sealing work of a whirling well cone-bottomis finished by arranging a precipitation well; the main body of the precipitation well is a steel pipe; the length of the steel pipe is as same as the depth of the precipitation well; the precipitation well comprises an upper opening and a lower opening; a flange is connected to the upper opening; gaps are uniformly formed at the lower opening along the surrounding of the bottom of the steel pipe;and a water outlet and a water pumping opening for a vacuum pump are formed in the middle part of the precipitation well. According to the whirling well cone-bottom sealing method, by using a methodof burying the precipitation well and using a blind plate and a flange to plug, the concrete bottom sealing work of the whirling well cone-bottom can be safely and rapidly finished so that the cost ofa dewatering and drainage m |
