Embodiment 1
[0040] An internal pressure-deformable lining pipe used for the lining of existing pipelines, including a hollow connecting pipe 1 and a fillet 2, such as figure 1 As shown, the specific structure is:
[0041] The outer wall of the connecting pipe 1 is provided with six slots 11 with an arc-shaped cross section, and the slots 11 are evenly distributed around the central axis of the connecting pipe 1;
[0042] The fillet 2 can be wire or optical fiber, the cross-section of the fillet 2 is circular, the radius of the cross-section of the fillet 2 is not greater than the radius of curvature of the cross-section of the fillet 11, and the diameter of the fillet 2 is greater than the depth of the cross-section of the fillet 11 , a fillet 2 is embedded in each caulking groove 11, the outermost part of the outer surface of the fillet 2 is higher than the outermost part of the outer side wall of the connecting pipe 1, and the two ends of the fillet 2 protrude from the front and rear si...
Embodiment 2
[0054] An internal pressure-deformable lining pipe used for the lining of existing pipelines, including a hollow connecting pipe 1 and a fillet 2, such as figure 2 As shown, the specific structure is:
[0055] The outer wall of the connecting pipe 1 is provided with four slots 11 with an arc-shaped cross section, and the slots 11 are evenly distributed around the central axis of the connecting pipe 1;
[0056] Nylon rope or steel wire rope can be used for the fillet 2. The cross section of the fillet 2 is circular. The radius of the cross section of the fillet 2 is not greater than the radius of curvature of the cross section of the fillet 11. Depth, a fillet 2 is embedded in each insert groove 11, and the outermost part of the outer surface of the fillet 2 is figure 2 The dotted line in the circle shows that it is higher than the outermost part of the outer wall of the connecting pipe 1. The two ends of the fillet 2 protrude from the front and rear ends of the connecting p...
