[0028] Exemplary embodiments of the present disclosure will be described in greater detail below with reference to the accompanying drawings.

[0029] EMBODIMENT

[0030] As mentioned in the background, the corrugated pipe has a wide range of uses, but in actual manufacturing and use, the inventor found that the existing corrugated pipe has many defects, and the annular protrusion 2 on the outer end surface is very easy to deform, mainly because of the structure of the annular protrusion 2 itself, which has an annular cavity and is not easy to withstand a large load. Therefore, the inventor has made innovative improvements and designed a new type of corrugated pipe to improve the load-bearing strength. The specific description will be expanded below in conjunction with the drawings.

[0031] The embodiment provides a double-ladder high-rib reinforced corrugated pipe, which is shown in Figure 1 and Figure 2 , comprising a pipe body 1, the pipe body 1 is circular in cross-sectional shape and is made of an oxidation-resistant material, the outer edge surface of the pipe body 1 is connected with a plurality of annular protrusions 2, the annular protrusions 2 are arranged along the length direction of the pipe body 1, specifically, in combination with Figure 3 , the outer end surface of the pipe body 1 is adhesively fixed with a plurality of annular bottom plates 6, and the plurality of annular protrusions 2 are respectively adhesively fixed with the plurality of annular bottom plates 6, by arranging the annular bottom plates 6, the connection of the annular protrusions 2 and the pipe body 1 is facilitated, and the annular bottom plates 6 and the annular protrusions 2 are both made of an oxidation-resistant material, in the present scheme, a rubber material is used, which can improve the service life.

[0032] On the basis of the above structure, one end of the annular bottom plate 6 is provided with a limiting strip 7 close to the end surface of the annular protrusion 2, and the limiting strip 7 is abuttingly fixed with the bottom of the annular protrusion 2, by arranging the limiting strip 7, one side of the annular protrusion 2 can be limited, so as to ensure the stability of the annular protrusion 2.

[0033] In this embodiment, the annular protrusion 2 has an annular cavity 3, which means that a circle is opened around the annular protrusion, and in order to improve the strength and anti-deformation effect of the annular protrusion 2, the cross-sectional shape of the annular protrusion 2 and the annular cavity is trapezoidal or rectangular. In this scheme, the cross-sectional shape of both is trapezoidal.

[0034] On the basis of the above-mentioned mechanism, the annular cavity 3 is filled with a reinforcing frame 4, which is annular as a whole. Specifically, in combination with Figure 3 , the reinforcing frame 4 includes a hollow outer skeleton 41, the cross-sectional shape of the outer skeleton 41 is consistent with the cross-sectional shape of the annular cavity 3, which ensures that the outer skeleton 41 abuts against the inner wall of the annular cavity 3, and in order to improve the connection stability of the outer skeleton 41 and the annular cavity 3, the outer end surface of the outer skeleton 41 is provided with a limiting groove 44, and the inner wall of the annular cavity 3 is provided with an integrally formed limiting protrusion 5, which can be clamped with the limiting groove 44. Moreover, the limiting groove 44 is provided with two limiting grooves, which are opposite to the two end surfaces of the outer skeleton 41 close to and away from the pipeline body 1, and the limiting protrusion 5 is provided with two limiting protrusions at the corresponding position. Through the mutual adaptation of the two limiting protrusions 5 and the two limiting grooves 44, the reinforcing skeleton can be limited, which ensures its stability.

[0035] In addition, in combination with Figure 4 , the reinforcing frame 4 further includes a reinforcing rib 42 located in the outer skeleton 41, and the reinforcing rib 42 is integrally formed with the outer skeleton 41. The vertical plane where the reinforcing rib 42 is located is perpendicular to the extension direction of the pipeline body 1, that is, the cross-sectional extension direction of the reinforcing rib 42 is consistent with the high extension direction of the trapezoidal cross-sectional annular cavity 3. Specifically, one side of the reinforcing rib 42 is set to be wavy along the length direction of its cross-section, that is, the wavy extension direction is consistent with the radial direction of the pipeline body 1, and the other side is set to be planar. Through this setting, the deformation amplitude of the reinforcing rib 42 under stress can be effectively reduced, and the reinforcing rib 42 can release stress when the reinforcing frame 4 is stressed in the radial direction, which effectively relieves the deformation of the reinforcing rib 42.
