Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The following describes the implementation of the present invention in detail with reference to specific embodiments.
As shown in fig. 1, in the embodiment of the present invention, a novel dewatering well structure is provided, which comprises a sealed well casing 1, a gas pipe 2 connected with the well casing 1, a water outlet pipe 3 connected with the well casing, a central pipe 4 suspended in the well casing 1 and having an upper opening and a lower end sealed, and an annular air bag 5 arranged between the well casing 1 and the central pipe 4. The annular air bag 5 is provided with an air bag air pipe 6 extending out of the well casing 1 and used for inflating the annular air bag 5, so that the annular air bag 5 is expanded, pressure is applied to the central pipe 4 and the pipe wall of the well casing 1, the central pipe 4 is fixed and a gap between the well casing 1 and the central pipe 4 is sealed, and the central pipe 4 and the annular air bag 5 divide the well casing 1 into an upper cavity 11 of a dewatering well and a lower cavity 12 of a dewatering well.
As shown in fig. 2 and 3, the annular bladder 5 is annular, and an annular rib 7 for supporting is provided on an inner periphery thereof to maintain the shape of the annular bladder 5 when the annular bladder 5 is not inflated so as to fit over the central tube 4.
The well pipe 1 is sealed by a well lid 13. One end of the air pipe 2 penetrates through the central pipe 4 to be communicated with the lower cavity 12 of the dewatering well, and the other end of the air pipe is arranged outside the well pipe 1.
