| description | The utility model provides a foundation pit inrush rescue self-balancing dewatering well device which comprises an outer sleeve pressed into soil, a water filter pipe exposed in the soil body is arranged at the bottom of the outer sleeve, the water filter pipe is communicated with a center hole of the outer sleeve, and the water filter pipe is communicated with a water inlet of the outer sleeve. A double water stop device is connected between the outer wall of the water filter pipe and the inner wall of the outer sleeve, and a bottom opening of the water filter pipe is connected with a sealing device. Compared with the conventional well completion, the construction period can be shortened by 2/3, the precipitation operation can be quickly completed, and precious time is won for rescue work; after the outer sleeve is pulled upwards, on one hand, the water filtering pipe is exposed in the soil body, the contact area with underground water is increased, and the precipitation speed is increased; on the other hand |
