[0002] The winding tube is a new product that replaces the traditional metal spring guard used for hose protection. The winding tube is generally made of nylon or polypropylene. Compared with the traditional metal spring guard products, the winding tube has good wear resistance, anti-aging and strong corrosion resistance.

[0003] Most of the existing wall pipes need to be buried underground. The wall pipes need to withstand the pressure of the soil and road surface above, as well as the impact of the internal water flow. Therefore, most water pipes need to be equipped with winding reinforcement on the outside to enhance the strength of the overall wall pipe. However, the existing structure only has a layer of spiral reinforcement on the outer layer, and the reinforcement effect is not obvious enough to meet the compressive strength requirements.

[0006] Preferably, the docking mechanism includes a second tube body, a rubber ring, a docking cylinder and fastening holes. The outer side of the second tube body is provided with docking cylinders at equal intervals in a ring shape. Fastening holes are penetrated through the surface of the docking cylinder. The outer side of the second tube body is snap-connected with a rubber ring, and the other end of the second tube body is connected to the inside of an outward expansion connecting pipe.
