[0027] like Figure 3 As shown, the clamping plate assembly 11 includes a positioning base plate 110, a support plate 111, and a movable plate 112 forming a U-shape. The positioning base plate 110 is perpendicular to the support plate 111 and is formed by bending. The movable plate 112 is parallel to the positioning base plate 110 and is movably connected to the support plate 111. The rubber waterstop 3 is clamped between the positioning base plate 110 and the movable plate 112.

[0028] like Figures 3-4 As shown, the support plate 111 has a built-in double slide rail, and the movable plate 112 is movably connected to the slide rail via the slider 113; the slide rail is T-shaped, and the slider 113 matches the slide rail and is welded to fix the movable plate 112; the positioning base plate 110 and the movable plate 112 are equipped with reinforcement parts; the reinforcement parts include a screw part 114 and a nut 115, one end of the screw part 114 is welded to the positioning base plate 110, and the other end passes through the movable plate 112, the nut 115 is threaded to the screw part 114 and pressed against the surface of the movable plate 112; the nut 115 is symmetrically welded with a handle part.

[0030] The working principle of the waterstop fixing device for water conservancy projects according to this utility model is as follows:

[0031] Before installation, the concrete surfaces on both sides of the joint are cleaned and leveled to ensure the bonding quality between the rubber waterstop 3 and the concrete. The reinforcing bar assembly 12 is fixedly connected to the outer surface of the support plate 111, thus pre-setting the positioning brackets 1 on both sides of the joint. The opening diameter of the clamping plate assembly 11 is adjusted according to the size of the rubber waterstop 3. Then, the rubber waterstop 3 is embedded between the symmetrically arranged positioning brackets 11, and the rubber waterstop 3 is firmly fixed to both sides of the joint using reinforcement components. The length of both ends of the rubber waterstop 3 extends beyond the joint, leaving sufficient space for installing the positioning brackets 2. The two ends of the rubber waterstop 3 are then bidirectionally fixed using the positioning brackets 2. Finally, a sealing layer is filled in the joint area, and a protective layer is applied on-site using a flexible membrane material to cover the sealing layer and the outer ends of the rubber waterstop 3. An activator and adhesive are applied between the protective layer and the rubber waterstop 3 to enhance the connection strength. After installation, the entire joint and the rubber waterstop 3 are inspected for quality, and the sealing performance of the rubber waterstop 3 is evaluated using non-destructive testing methods.
