AI Technical Summary
In the use of existing steel-plastic composite pipes, the steel frame is prone to fall off and has poor corrosion resistance, resulting in a shortening of the service life of the pipe.
A buried MPVE high-strength steel-plastic composite pipe is designed, and the outer part of the pipe body is provided with a cladding layer and several Ω-type support structures. The bent parts on both sides of the support structure are engaged with the upper extension of the T-shaped winding strip, limiting the movement of the support structure, and at the same time, polyethylene cladding is used to protect the pipe body.
Through the engagement design of the support structure and the winding strip, the connection strength of the pipe is enhanced. The polyethylene cladding not only protects the pipe body from corrosion, but also further limits the movement of the support structure, improving the service life and simplicity of the pipe.

[0018] Embodiment 1
[0019] Refer to Figure 1 , an MPVE high-strength steel-plastic composite pipe for buried use, including an MPVE pipe body. An external coating layer 3 is provided on the MPVE pipe body. A plurality of support structures 2 are provided at intervals between the outer circumference of the MPVE pipe body and the coating layer 3. At least one winding strip 1 is provided between two adjacent support structures 2.
[0020] In this embodiment, the winding strip 1 is T-shaped, the support structure 2 is Ω-shaped, and its bending part 4 is smooth and the internal stress is uniform.
[0021] In this embodiment, the upper extension part 5 of the winding strip 1 abuts against the side bending part 4 of the support structure 2 close to the winding strip 1, and the bending part 4 is clamped to the upper extension part 5, restricting the support structure 2 and preventing it from sliding.
[0022] In this embodiment, the height of the support structure 2 is higher than the height of the winding strip 1. The support structure 2 first receives the pressure from the outside world and then transmits it to the winding strip 1, protecting the MPVE pipe body.
[0023] In this embodiment, the distance between adjacent winding strips 1 is adapted to the size of the support structure 2, increasing the connection strength.
[0024] In this embodiment, two winding strips 1 are provided between two adjacent support structures 2 to ensure that one winding strip 1 abuts against one support structure 2, increasing the connection strength. The winding strips 1 are integrally arranged to further enhance the connection strength and make the connection more firm.
[0025] In this embodiment, the winding strips 1 are evenly distributed along the circumferential direction of the MPVE pipe body, so that the MPVE pipe body is stressed evenly.
[0026] In this embodiment, the material of the coating layer 3 is polyethylene, which can protect the MPVE pipe body from corrosion and has a light overall weight.
[0027] In this embodiment, the outer shape of the coating layer 3 fits the winding strips 1 and the support structure 2. The coating layer 3 further restricts the movement of the support portion 2 and increases the connection strength.
[0028] The technical solution of the present utility model has been fully described above. It should be noted that the specific implementation manner of the present utility model is not limited by the above description. All technical solutions formed by equivalent transformation or equivalent transformation in terms of structure, method or function, etc. by those of ordinary skill in the art according to the spirit of the present utility model fall within the protection scope of the present utility model.
