DETAILED DESCRIPTION

[0027] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0028] Embodiments

[0029] As mentioned in the background, the existing corrugated pipe has the problem of poor strength and easy deformation in actual use. Especially in the fields of municipal drainage, farmland irrigation and power communication, the corrugated pipe needs to withstand large external pressure and foundation settlement and the like. The traditional corrugated pipe usually adopts a hollow design with a circular or square cross section, and the strength is improved by increasing the pipe wall thickness, but this way has limited effect and cannot effectively solve the deformation problem, which will be described in detail below with reference to the drawings.

[0030] The present embodiment provides a multi-shaped double-resistant multi-reinforced pipe, as shown in Figure 1 The reinforcing pipe includes a main body section 1 and a plurality of corrugated sections 3. The main body section 1 is a tubular structure, and the corrugated sections 3 are usually designed in a wave shape or a ring-shaped corrugated shape to improve the flexibility and pressure resistance of the pipe. The corrugated sections 3 are uniformly arranged along the length direction of the main body section 1, and the corrugated sections 3 are made of an anti-oxidation and anti-static material, for example, a high-strength polyethylene and glass fiber mixed material (glass fiber 20%-30%), and 2%-5% of double-resistant master batch can be added during production, or other anti-oxidation and anti-static materials of the prior art can be used. The corrugated sections 3 are provided with a cavity 2 and a reinforcing structure 4, for example, the reinforcing structure 4 can be made of high-density polyethylene (HDPE) material.

[0031] Moreover, the cross section of the corrugated section 3 is rectangular or trapezoidal, and in this embodiment, the trapezoidal structure is designed, which provides a new selection of the cross section shape of the corrugated section 3, and can improve the structural strength and stability of the corrugated pipe. By changing the cross section shape of the corrugated section 3, the external pressure can be better dispersed and borne, thereby improving the pressure resistance and deformation resistance of the corrugated pipe. In addition, the bottom plate layer 7 is arranged between the corrugated section 3 and the main body section 1, and the bottom plate layer 7 is adhesively fixed with the corrugated section 3 and the main body section 1, respectively. The connection stability between the corrugated section 3 and the main body section 1 is realized by arranging the bottom plate layer 7. The bottom plate layer 7 not only adhesively fixes the corrugated section 3 and the main body section 1 together, but also enhances the stability of the overall structure.

[0032] On the basis of the above structure, the upper end surface of the bottom plate layer 7 is designed as a U-shaped structure, and the bottom of the corrugated section 3 abuts against the two sides of the U-shaped structure. By designing the upper end surface of the bottom plate layer 7 as a U-shaped structure and making the bottom of the corrugated section 3 abut against the two sides of the U-shaped structure, the contact area between the corrugated pipe and the main body section 1 can be increased, and the corrugated section 3 can be limited, thereby improving the stability and pressure bearing capacity of the connection, and avoiding the problems of deformation or falling off of the corrugated pipe due to insecure connection during use.

[0033] In this embodiment, the reinforcing structure 4 includes an outer reinforcing frame 41 and an inner reinforcing frame 42. The outer reinforcing frame 41 is connected to the inner reinforcing frame 42 and the inner wall of the cavity 2. The inner reinforcing frame 42 is a polygonal structure and is connected to the side wall of the cavity 2 and the inner wall close to the main body section 1. Through this design, the reinforcing structure 4 provides additional support, improves the pressure resistance and structural stability of the corrugated pipe, and thus improves the service life and performance of the corrugated pipe. The cross section of the outer reinforcing frame 41 is rectangular as a whole and is perpendicular to the outer wall of the corrugated section 3, which can support the stress direction of the corrugated section 3 and improve the stability. In addition, the side of the outer reinforcing frame 41 close to the inner wall of the cavity 2 is formed with a limiting protrusion 43, and the inner wall of the cavity 2 is formed with a limiting groove 5 matched with the limiting protrusion 43. The limiting protrusion 43 can enter the limiting groove 5, and the two are limited to each other to ensure the fastening of the installation of the outer reinforcing frame 41. In addition, a plurality of release holes 44 are formed in the outer reinforcing frame 41 in the vertical direction. By arranging the release holes 44, when the corrugated section 3 is extruded, the release holes 44 can release the stress causing the deformation of the outer reinforcing frame 41.

[0034] On the basis of the above structure, the cross section of the inner reinforcing frame 42 is a hollow triangular structure, and the three corners are respectively connected with the two side walls of the cavity 2 and the inner wall close to the main body section 1. This connection mode ensures the stability of the inner reinforcing frame 42 in the cavity 2 and is not easy to displace and deform. By adopting the hollow triangular structure of the inner reinforcing frame 42 and connecting its three corners with the two side walls of the cavity 2 and the inner wall close to the main body section 1, the problem of stable connection of the inner reinforcing frame 42 in the reinforcing pipe is solved. This design not only improves the stability of the reinforcing frame, but also enhances the overall strength and pressure resistance of the pipe.

[0035] In addition, the two side walls of the cavity 2 and the inner wall close to the main body section 1 are formed with accommodating grooves 6, and the three corners of the inner reinforcing frame 42 are respectively matched with the corresponding accommodating grooves 6. The three corners of the inner reinforcing frame 42 can enter the accommodating grooves 6 to limit the inner reinforcing frame 42, ensuring the stability of the connection between the inner reinforcing frame 42 and the cavity 2. In addition, the cross-sectional height of the inner reinforcing frame 42 can be designed to be between 1 / 2 and 2 / 3 of the cross-sectional height of the cavity 2, so as to ensure that it provides sufficient supporting force while not occupying too much internal space of the cavity 2.
