Example 3
As shown in fig. 2 and 4 to 8, since the two water stop half rings 3 encase the steel casing 10 and form a water stop structure. There is a risk of leakage at the seam of the two water stop half rings 3. Therefore, on the basis of embodiment 2, the water stop semi-ring 3 comprises an arc-shaped block 31, the arc-shaped block 31 is fixedly connected with a supporting rod 43, the upper side of the arc-shaped block 31 is fixedly connected with a round rod 32, the outer side of the upper end part of the round rod 32 is fixedly connected with a rubber plate 33, the outer arc surface of the rubber plate 33 is in sliding connection with an inner frame 34, an avoidance through groove 341 is formed in the upper side of the inner frame 34, and the radian of the avoidance through groove 341 is identical to that of the upper surface of the inner frame 34. The upper end of the round rod 32 passes through the avoidance through groove 341, and the inner frame 34 can rotate by taking the circle center of the rubber plate 33 as a reference. In this embodiment, the rubber plate 33 is fixedly connected to the supporting frame inside for maintaining the shape of the rubber plate 33. When the round bar 32 is connected with the rubber plate 33, the upper end part of the round bar 32 stretches into the rubber plate 33 and is fixedly connected with the supporting framework, so that the structural strength of connection is improved.
The cross section of the rubber plate 33 is U-shaped, and the U-shaped notch of the rubber plate 33 is located on the outer arc surface, and the inner frame 34 is slidably arranged in the U-shaped notch of the rubber plate 33.

In this embodiment, the inner frame 34 is rotated relative to the rubber plate 33 by using the arc-shaped block 31 and the rubber plate 33 as references and keeping the same. In the process of rotating, the end of the inner frame 34 is inserted into the opposite rubber plate 33 from the original rubber plate 33, and the joint of the two combined rubber plates 33 is additionally supplemented with water to avoid incomplete sealing caused by the joint of the two rubber plates 33, so that the stability of water stopping is improved.
The rubber slab 33 both ends set up arc protruding 331, and inside casing 34 corresponds the position of arc protruding 331 and sets up arc recess 332, and arc protruding 331 can get into in the arc recess 332 after inside casing 34 rotates.
