Description

Technical Field

[0001] The utility model relates to the field of water-stop screws, in particular to a water-stop screw for reinforcing a box culvert side wall. Background Art

[0002] The water-stop screw used in the reinforcement of the box culvert side wall is an important component to ensure the stability and waterproof performance of the box culvert structure. It is mainly divided into two types: the old-style through-thread water-stop screw and the new three-stage water-stop screw. Taking the vertebral three-stage water-stop screw as an example, it consists of an inner rod, two vertebral connecting nuts, and two outer rods. The inner rod remains in the wall and is equipped with a water-stop sheet to play a water-stopping role; the outer rod has a thick wire at one end and a thin wire at the other end, and the thin wire is connected to the inner rod through the vertebral connecting nut, which has strong stability. The advantage of this screw is that the outer rod can be disassembled, and the template will automatically fall off after disassembly, saving time and labor, and the outer rod can be reused, reducing costs.

[0003] A Chinese patent document with authorization announcement number CN218815245U proposes a new type of water-stop tension screw, including a fixed inner rod, a water-stop mechanism is arranged in the middle part of the fixed inner rod, the water-stop mechanism includes a first water-stop plate and a second water-stop plate, the first water-stop plate and the second water-stop plate are both hemispherical, both ends of the fixed inner rod are symmetrically threaded with a movable inner rod, and a conical block is arranged near the outer end of the movable inner rod.

[0004] In the above application, although the fixed inner rod penetrates the center of the first water stop plate and the second water stop plate, and the intersection is tightly welded, which can effectively block the transfer of water and ensure the water stop effect, the installation and disassembly of the device is relatively complicated and time-consuming and labor-intensive.
