Description

Technical Field

[0001] This utility model relates to the field of PE spiral corrugated pipe technology, specifically a municipal-specific internally reinforced PE spiral corrugated pipe. Background Technology

[0002] The internally ribbed reinforced polyethylene spiral corrugated pipe features a rationally designed spiral corrugated structure, which facilitates a wider contact surface with the soil. This allows the backfill soil filling the pipe's troughs and the pipe itself to jointly withstand the pressure from the surrounding soil, creating a system of pipe-soil compressive strength. Internally ribbed reinforced polyethylene spiral corrugated pipe also boasts significant advantages such as lightweight, high strength, good toughness, good wear resistance, corrosion resistance, smooth inner wall, low flow resistance, convenient installation, and long service life.

[0003] Patent document CN222277843U discloses a PE internally ribbed reinforced corrugated pipe, "including a pipe body, which includes an outer pipe wall and an inner pipe wall. The pipe body is provided with a corrugated cavity formed by stacking the outer pipe walls. A concave trough is formed between the two corrugated cavities. A mesh belt is provided between the outer and inner pipe walls at the trough. The two sides of the mesh belt are fixedly connected to the inner and outer pipe walls respectively. The PE internally ribbed reinforced corrugated pipe described in this application uses a three-dimensional mesh support belt to open up the two pipe walls. By increasing the distance between the two pipe walls, pressure or weak tension is formed on the inner wall to prevent it from being torn. The mesh support belt increases the overall rigidity at the trough position." The corrugated pipe in this patent document increases the compressive strength of the corrugated pipe by installing ribs. However, the ribs are rectangular strips, which are easy to bend after being squeezed, resulting in a decrease in the compressive strength of the corrugated pipe.

[0004] In view of this, it is necessary to develop a special municipal-grade internally reinforced PE spiral corrugated pipe, which can enable the corrugated pipe to have good pressure resistance and impact resistance for a long time. Utility Model Content

[0007] Preferably, the inverted trapezoidal reinforcing inner rib assembly includes a reinforcing inner rib body and a through hole. The reinforcing inner rib body is installed inside the outer spiral body and has an inverted trapezoidal structure. The bottom of the reinforcing inner rib body is connected to the bottom inner wall of the outer spiral body, and the through hole is opened through the outer side of the reinforcing inner rib body.

[0008] Preferably, an arc-shaped connector is installed on the top of the reinforcing inner rib body.

[0009] Preferably, a protective gasket is installed on the inner wall of the outer spiral body, and the top inner wall of the protective gasket is connected to the top arc of the arc connector.

[0010] Preferably, the inverted trapezoidal structure of the reinforcing inner rib body is an isosceles trapezoid.

[0011] Preferably, the top arc surface of the arc connector matches the top inner arc of the protective pad.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0022] Please see Figures 1-4 A municipal-grade internally reinforced PE spiral corrugated pipe;

[0023] Includes: a spiral corrugated pipe body 1, which includes a pipe body 2 and an outer spiral body 3. The outer spiral body 3 is spirally wound around the outside of the pipe body 2 and has a hollow internal structure. An inverted trapezoidal reinforcing inner rib assembly 5 is installed inside the outer spiral body 3. The inverted trapezoidal reinforcing inner rib assembly 5 is used to increase the pressure resistance and impact resistance of the spiral corrugated pipe body 1.

[0024] The spiral corrugated pipe body 1 is a pipe formed by extrusion and concave winding of high-density polyethylene as the matrix. Its outer wall is spirally corrugated, and there are vertical ribs made of polyethylene material and two oblique support ribs with the vertical ribs as the plane of symmetry. In order to further improve the compressive strength of the spiral corrugated pipe body 1, an inverted trapezoidal reinforcing inner rib assembly 5 is installed inside the outer spiral body 3. The inverted trapezoidal reinforcing inner rib assembly 5 provides support inside the outer spiral body 3, thereby increasing the compressive and impact resistance of the spiral corrugated pipe body 1.

[0025] The inverted trapezoidal reinforcing inner rib assembly 5 includes a reinforcing inner rib body 6 and a through hole 7. The reinforcing inner rib body 6 is installed inside the outer spiral body 3 and has an inverted trapezoidal structure. The bottom of the reinforcing inner rib body 6 is connected to the bottom inner wall of the outer spiral body 3. The through hole 7 is opened through the outer side of the reinforcing inner rib body 6. The inverted trapezoidal structure of the reinforcing inner rib body 6 is an isosceles trapezoidal shape.

[0026] In the inverted trapezoidal reinforcing inner rib assembly 5, the reinforcing inner rib body 6 is an inverted isosceles trapezoidal structure. The top is tightly connected to the outer spiral body 3 through the arc connector 8. Since the reinforcing inner rib body 6 is an inverted isosceles trapezoidal structure, compared with the rectangular strip-shaped inner rib, the reinforcing inner rib body 6 has a better support effect and is not easy to bend. It can provide good support inside the outer spiral body 3. The through hole 7 is used to reduce the weight of the reinforcing inner rib body 6 and reduce the impact of the installation of the reinforcing inner rib body 6 on the weight of the bellows.

[0027] The top of the reinforcing inner rib body 6 is equipped with an arc-shaped connector 8, and the top arc surface of the arc-shaped connector 8 matches the top inner arc of the protective pad 4.

[0028] The installation of the arc connector 8 allows the top of the reinforcing inner rib body 6 to fit tightly against the inside of the outer spiral body 3, thereby improving the stability of the reinforcing inner rib body 6 installed inside the outer spiral body 3.

[0029] A protective gasket 4 is installed on the inner wall of the outer spiral body 3, and the top inner wall of the protective gasket 4 is connected to the top arc of the arc connector 8.

[0030] The protective pad 4 is made of cut-resistant and wear-resistant material and is used to protect the inverted trapezoidal reinforcing inner rib assembly 5 inside the outer spiral body 3, so that the inverted trapezoidal reinforcing inner rib assembly 5 can be used stably and safely inside.

[0031] Working principle: First, the spiral corrugated pipe body 1 serves as a transmission pipeline, providing space for the transmission of fluids and gases. In order to improve the pressure resistance of the spiral corrugated pipe body 1, an inverted trapezoidal reinforcing inner rib assembly 5 is installed inside the outer spiral body 3 to increase the ring stiffness of the spiral corrugated pipe body 1, thereby improving the pressure resistance and impact performance of the spiral corrugated pipe body 1. At the same time, a through hole 7 is provided in the reinforcing inner rib body 6 in the inverted trapezoidal reinforcing inner rib assembly 5, thereby reducing the weight of the reinforcing inner rib body 6.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
