| titleOfInvention | A kind of super waterproof capacity concrete pipe pile and its production process |
| abstract | The invention discloses a concrete pipe pile with super waterproof capacity and a manufacturing process thereof, and belongs to the technical field of pipe pile manufacturing technology. Including: a concrete pile body and several hourglass-shaped small holes opened on the concrete pile body; the concrete ratio in the concrete pile body is: cement, silica fume, fly ash, sand, stone, limestone powder , sepiolite fibers and titanium dioxide. According to the invention, a number of hourglass-shaped small holes are punched on the existing pipe pile, so that when there is water flow in the ground, it is convenient for water to enter the pipe pile from the hourglass-shaped small holes, which plays a role of drainage and prevents the accumulation of water flow to the pipe. The pressure of the pile increases, and the small hole is hourglass type and there is no gap in the middle, that is, there is a supporting force inside the small hole, which reduces the damage to the pipe pile at the opening when the water flow passes through the small hole, and there is no gap in the middle. The gap reduces the possibility of sand and mud entering the pipe pile; and water reducing agent and waterproofing agent are added to the concrete, which can effectively increase the prestressing and waterproofing ability of the concrete. |
