Embodiment Construction
[0009] A leak-proof process for sealing the wall of the suspended cold water pool of Ouyeel furnace by expanding holes and piercing pipes, such as figure 1 , figure 2 As shown, the following steps are included: ① First, the original pipe hole on the pool wall 4 is continued to be reamed, so that when the pipe 1 passes through, there is a grouting distance of 40-70mm between the pipe wall and the hole wall, and the pipe 1 is in contact with the pool wall. Vertical, the surface of the waterproof layer inside the pool wall 4 is roughened; ② After the hole is expanded, the inner flange piece 2 is set on the pipe 1 in advance, or the inner flange piece 2 is put on the pipe 1 after passing through the pool wall 4 Split and welded on the pipe 1, the inner ring of the inner flange 2 is provided with a chamfer, the size of the chamfer is at least 45 degrees; It is fully welded with the outer wall of the pipe 1, and the weld seam 7 is relatively uniform due to the large chamfer of the...
