[0002] In the field of engineering construction, hot-melt welding of flexible pipes is often encountered, and it is often necessary to hot-melt weld pipe fittings and pipe openings, and between pipe openings. Since flexible pipes often need to undergo long-term transportation and on-site construction hoisting, the pipe openings are prone to deformation. The deformation of the pipe openings needs to be adjusted before hot-melt welding, and the pipe openings to be hot-melt welded need to be in a stable state during construction. At present, there is no dedicated adjustment device in the prior art, and the two sides of the pipe openings are only adjusted by hoisting at the joints, which is not ideal, and it is very easy for the hot-melt welding quality to fail to meet the standards due to the instability of the pipe openings.

[0027] Specifically: the first arched supporting curved panel 1 and the first panel fixing rod 3 are welded firmly, and the second arched supporting curved panel 8 and the second panel fixing rod 7 are welded firmly, so as to form a stable force-bearing system with simple structure and remarkable effect.

[0028] Furthermore, the first arched supporting curved panel 1 and the second arched supporting curved panel 8 are both made of Q235 ordinary carbon steel, which is easy to obtain on site and simple to manufacture; the curvature of the first arched supporting curved panel 1 and the second arched supporting curved panel 8 are consistent; the first arched supporting curved panel 1 is welded downward with an arc opening on the upper end of the supporting screw 2; the second arched supporting curved panel 8 is welded upward with an arc opening on the lower end of the supporting steel casing 4.
