Embodiment Construction
[0037] A jacket ice-breaking structure with a vacuum cavity: such as Figure 7 As shown, it includes ice-breaking element 1, jacket rod 2, and steel pipe pile 8. The outer side of jacket rod 2 is covered with ice-breaking element 1. Ice-breaking element 1 and jacket rod 2 are connected by welding. Jacket rod 2 and The steel pipe piles 8 are connected by grouting or welding. The upper part of the steel pipe pile 8 structure is the jacket rod 2, and the lower part goes deep into the seabed. The whole structure is supported by the steel pipe pile 8 foundation and fixed at sea.
[0038] Such as Figure 8-12 As shown, the ice breaking element 1 includes a cone ring 3, a ball plate 4, a round rod 5, a spring 6, a vacuum valve 7 and a cylinder 9, and the cylinder 9, the ball plate 4 and the round rod 5 are all made of stainless steel alloy materials, and the outer Coated with epoxy resin type heavy-duty anti-corrosion coating. The cone ring 3, the spring 6, and the vacuum valve 7 a...
