As a further optimization of the above scheme, the part of the outer side of the first type strip material, which is higher than the outer side of the second type strip material, is arc-shaped.
As a further optimization of the scheme, a first type cavity with the same trend is formed in the first type strip, and a supporting piece is arranged in the first type cavity to support the outer side surface of the first type strip to form an arc surface.
As a further refinement of the above solution, the support is a corbel arranged perpendicular to the inner wall of the main pipe body, and the corbel extends along the run of the first type of strip.
As a further optimization of the scheme, the abutting portions extend out of the two ends of the top and the bottom of the supporting beam, and the abutting portions located at the top ends of the supporting beam are provided with arc-shaped peripheries to jack up the outer side surfaces of the first type of strip.
As a further refinement of the above solution, the support is integrally formed with the first type of strip.
1. According to the HDPE hollow wall winding pipe provided by the utility model, the main pipe body of the winding pipe is formed by alternately and spirally winding the first type belt material and the second type belt material, so that the main pipe body has certain relative independence, and when a certain part is subjected to pressure, the influence of the part transmitted to other areas on the periphery of the main pipe body is small, so that the winding pipe can be prevented from being broken due to uneven stress.
2. According to the HDPE hollow wall winding pipe provided by the utility model, the first type belt material is wound on itself to form the external thread structure of the winding pipe, so that the compression resistance of the winding pipe is improved to a certain extent, and the compression resistance of the winding pipe is further improved by reinforcing the supporting piece.

Detailed Description
The HDPE hollow wall winding pipe according to this embodiment, referring to fig. 1, comprises a main pipe body 1 and an insulation fabric 2, wherein the main pipe body 1 is formed by alternately and spirally winding a first type strip 11 and a second type strip 12, the first type strip 11 is flush with and tightly jointed with the inner side of the second type strip 12 to form the inner wall of the main pipe body 1, and the insulation fabric 2 is attached to the outer side of the main pipe body 1 to cover the first type strip 11 and the second type strip 12.
In the present embodiment, the thickness of the first type strip 11 is greater than that of the second type strip 12 so that a spiral rib is formed outside the main pipe body 1 as an external thread structure to improve the compression resistance of the wound pipe.
As a further embodiment, the outer side of the first type strip 11 is higher than the outer side of the second type strip 12 in an arc shape, the first type cavity 100 with the same trend is formed inside the first type strip 11, and the supporting piece 3 is arranged in the first type cavity 100 to support the outer side of the first type strip 11 to form an arc surface.
The support 3 is a supporting beam 31 which is arranged perpendicular to the inner wall of the main pipe body 1, the supporting beam 31 extends along the trend of the first type strip 11, the abutting portions 32 extend from the top end and the bottom end of the supporting beam 31, and the abutting portions 32 at the top end of the supporting beam 31 are provided with arc-shaped peripheries to jack up the outer side surface of the first type strip 11 to form an arc surface.
In the above embodiment, the support 3 is integrally formed with the first type strip 11.
According to the HDPE hollow wall winding pipe provided by the embodiment, the main pipe body of the winding pipe is formed by alternately and spirally winding the first type belt materials 11 and the second type belt materials 12, so that certain relative independence is achieved, when a certain part is stressed, the influence of other areas on the periphery of the main pipe body is small, and therefore breakage of the winding pipe caused by uneven stress can be avoided, meanwhile, the first type belt materials 11 are wound on themselves to form an external thread structure of the winding pipe, the compression resistance of the winding pipe is improved to a certain extent, and the compression resistance of the winding pipe is further improved through reinforcement of the supporting piece 3.
