Detailed Description

The utility model will be described in further detail with reference to the drawings and the detailed description. The embodiments of the utility model have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the utility model in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments were chosen and described in order to best explain the principles of the utility model and the practical application, and to enable others of ordinary skill in the art to understand the utility model for various embodiments with various modifications as are suited to the particular use contemplated.

Referring to fig. 1-4, in this embodiment, a dewatering well sealing structure is provided, which includes: the cover plate 1 is arranged on the upper end surface of the water stop sleeve through a bolt, so that the purpose of disassembly is realized, and when the phenomenon of sedimentation water leakage occurs, the cover plate can be disassembled through the bolt, so that the operation of secondary grouting plugging is convenient, the practicability is high, and the operation is convenient; the water-stopping sleeve is placed in the well pipe to play a role in blocking underground water; in the embodiment, a reinforcing steel bar net pipe 5 is fixed on the end face of the bottom of the water stop sleeve; the reinforcing mesh pipes 5 are inserted into the concrete in the well pipe, and in this embodiment, the reinforcing mesh pipes 5 are provided in plurality and are inserted into the poured concrete, and at the same time, the socket pipes 2 are supported on the concrete, thereby increasing the compactness on the first grouting plugging structure and preventing sedimentation.

The cover plate 1 is provided with a plurality of first screw holes 6, the first screw holes 6 are uniformly distributed circumferentially around the axis of the water-stop sleeve, the water-stop sleeve comprises a joint pipe 2, the top of the joint pipe 2 is provided with a plurality of second screw holes 7 which are matched with the first screw holes 6, and a plurality of bolts fix the cover plate 1 and the joint pipe 2 through the first screw holes 6 and the second screw holes 7.

The water stop sleeve further comprises a second water stop ring 3 and a first water stop ring 4, in this embodiment, the outer diameter of the joint pipe 2 is smaller than the inner diameter of the well pipe, the second water stop ring 3 and the first water stop ring 4 are fixed on the outer wall of the joint pipe 2, the inner wall of the second water stop ring 3 and the inner wall of the first water stop ring 4 are fixed on the outer wall of the joint pipe 2, and after the water stop sleeve is placed inside the well pipe, the second water stop ring 3 and the first water stop ring 4 can block underground water.
