In the case of freezing, when the ice layer expands and produces ice pull force, the rubber strip 6 can absorb and disperse the ice pull force through its own deformation, thereby protecting the dam. In addition, when the ice layer is affected by its own expansion force, it will slide upward along the surface of the crushing plate 11 and break, thereby reducing the ice pull force on the dam.

[0026] In this embodiment, quartz sand or corundum is sprayed on the outer surface of the concrete pouring surface 4 in sequence from top to bottom.

[0027] Local working principle: The setting of quartz sand or corundum materials can effectively increase the friction on the dam surface and prevent the damage to the dam caused by ice pull force.

[0030] In this embodiment, the sealing member is a rubber sleeve 19 , which is fixed on the polyethylene film layer 3 , and the rivet 17 passes through the inside of the rubber sleeve 19 .

[0031] Partial working principle: During the installation process of the rivet 17 , it passes through the inside of the rubber sleeve 19 to ensure the waterproof effect of the polyethylene film layer 3 .

[0033] Partial working principle: During the installation of the rubber strip 6, first insert the lower positioning block 9 at the bottom into the interior of the mounting groove 7. Since the lower positioning block 9 is inserted into the interior of the mounting groove 7 at an angle, it can be positioned at the bottom of the mounting groove 7 when subjected to an upward pull. Then fix the upper positioning block 8 to the top of the mounting groove 7 and use the fastening screw 10 to fix the top.

[0034] In this embodiment, the lifting mechanism includes a guide groove 12, a slide 13, a slide 14, a screw 15 and an adjusting wheel 16. The slide 13 is vertically opened inside the concrete casting surface 4, and the slide 13 is evenly opened on the side of the concrete casting surface 4, and the slide 13 is connected to the guide groove 12.

The top of the screw 15 is fixed with an adjusting wheel 16.

[0035] Partial working principle: Due to the different depths of the water surface, during use, the rotation of the screw 15 can be used to control the lifting of the slide plate 14, and then the lifting of the breaking plate 11 on the surface of the dam to ensure the ice breaking effect.

[0036] In this embodiment, the crushing plate 11 is in the shape of a right-angled trapezoid, the bottom of the crushing plate 11 is a cone, and the end of the crushing plate 11 is provided with an arc chamfer.
