Anti-floating system for underwater steel pipe encapsulation

The utility model discloses an anti-floating system for underwater steel pipe encapsulation. The anti-floating system comprises an embedded steel pipe, anti-floating underwater concrete, anti-floating I-shaped steel, an anti-floating steel wire rope and a template for pouring, the anti-floating steel wire rope is located on the top of the embedded steel pipe, the two ends of the anti-floating steel wire rope face downwards and connected with the anti-floating I-shaped steel located at the bottom of the foundation trench, and the anti-floating underwater concrete is supported by the formwork to be poured, further encapsulates the bottom of the embedded steel pipe and is formed. According to the utility model, the plurality of stressed anti-floating steel wire ropes and the anti-floating I-shaped steel are combined to form integral tension with the anti-floating underwater concrete of the foundation trench, so that the buoyancy of the underwater steel pipe and the upward friction force to the steel pipe during
