[0021] Reinforcing mechanism 4 includes spiral strip 501, the cavity 502 in the inside of spiral strip 501 is extruded and deformed to rebound, and the reinforcing wire 504 of iron in the inside of fixed strip 503 buffers the impact force, to improve the use strength of the outside of outer layer 1, the lower end of spiral strip 501 is fixedly connected with outer layer 1, the inner wall of spiral strip 501 is processed with cavity 502, the inner wall of spiral strip 501 is fixedly connected with fixed strip 503, the inner wall of fixed strip 503 is fixedly connected with reinforcing wire 504;

[0022] In the case where the thickness of outer layer 1 and inner layer 2 is unchanged, the cavity 502 in the inside of spiral strip 501 is extruded and deformed to rebound, and the reinforcing wire 504 of iron in the inside of fixed strip 503 buffers the impact force, to reduce the direct contact of external force with outer layer 1, and the high-strength overmolding steel wire net 4 is added in the inside of high-strength adhesive 3, so that the high-strength overmolding steel wire net 4 enhances the pulling force of outer layer 1 and inner layer 2, reduces the tearing damage of outer layer 1 and inner layer 2, and improves the use strength and use environment.

[0023] The inner wall of inner layer 2 is processed with first recess 6, the inner wall of first recess 6 is connected with connecting mechanism 7, connecting mechanism 7 includes left half ring 701, through the same structure second recess 8 on the surface of fixed cylinder 704, the outer wall of left half ring 701 and right half ring 702 can be tightly contacted, to realize the effect that multiple HDPE reinforced hollow winding pipes are connected with each other, the outer wall of left half ring 701 is tightly contacted with recess 6, the end of left half ring 701 is tightly contacted with right half ring 702, the inner wall of right half ring 702 is threadedly connected with fixed screw 703, the end of fixed screw 703 is tightly contacted with left half ring 701, the outer wall of left half ring 701 is tightly contacted with fixed cylinder 704, and the inner wall of fixed cylinder 704 is processed with second recess 8.
