The support assembly includes a support bracket 30 and a suspension hook 40 suspended on the support bracket 30, and the suspension hook 40 is adjusted up and down by a hand-cranked hoist 50. The support bracket 30 is adjusted to the embedded position and kept stable, and then the waterproof sleeve 10 is suspended above the embedded position by the suspension hook 40, and then the suspension hook 40 is controlled and the waterproof sleeve 10 connected to the water-stop steel plate 20 is unloaded to the embedded position by the hand-cranked hoist 50, ready for embedding.

[0039] like Figure 2 As shown, the axis of the waterproof sleeve 10 is arranged to intersect perpendicularly with the length of the water-stopping steel plate 20; and an arc-shaped groove for fixing the outer wall of the waterproof sleeve 10 is constructed on one end face of the length direction of the water-stopping steel plate 20, and the outer wall of the waterproof sleeve 10 is welded and fixed to the groove.

[0040] like Figure 1 As shown, the water stop steel plate 20 is arranged below the waterproof casing 10; or, as shown Figure 3 As shown, the water stop steel plate 20 is arranged above the waterproof casing 10. The two welding structures are often encountered in the commonly used pre-embedded treatment, and can be selected based on the actual working conditions.

[0041] like Figure 4 As shown, the water stop steel plate 20 is a steel plate with a special fold line structure, and its cross section is as follows Figure 5 As shown, it includes a straight section 21 in the middle and a folded section 22 at both ends. The folded section 22 is symmetrically arranged relative to the straight section 21, and the folded section 22 is tilted relative to the straight section 21, and the angle between them is an obtuse angle. Preferably, the angle between the straight section and the folded section is 135°, in order to prevent water from flowing through. A connecting curved surface of a semicircular arc surface 23 is provided at the center of the straight section 21, in order to improve the strength of the straight section at this position, and at the same time reduce the stress concentration at this position. Preferably, the opening of the semicircular arc surface 23 is arranged toward the inclined side of the folded section 22, and this structure is not only convenient for processing, but also easy to place.
