Description

Technical Field

[0001] The utility model relates to a pipeline, in particular to a reinforced pipe. Background Art

[0002] In recent years, with the huge demand for municipal pipes, many plastic pipes have emerged, such as PVC pipes, straight water pipes and winding corrugated pipes with ribs. The high-ribbed winding corrugated pipe with ribs is a high-ribbed ribbed pipe with a spiral wound around the pipe wall, and the strength of the pipe wall is strengthened by setting the high-ribbed ribbed pipe. However, the current high-ribbed winding corrugated pipe is usually only equipped with one hollow high-ribbed ribbed pipe. When the high-ribbed winding corrugated pipe is buried underground, the high-ribbed ribbed pipe will be subjected to pressure from all directions of the soil layer. Therefore, the high-ribbed winding corrugated pipe is easily deformed by compression. When the high-ribbed winding corrugated pipe is buried in a location with dense vehicle traffic or frequent earthquakes, the vibration of the ground is also easy to cause the winding corrugated pipe to break, and its compressive and seismic resistance is poor. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a reinforced pipe, which has better pressure resistance and shock resistance, is not easy to deform after being buried, and is not easy to break due to vibration.

[0004] In order to solve the above technical problems, the technical solutions adopted are as follows:

[0005] A reinforced tube comprises a tube body and a rib tube, wherein the rib tube is spirally wound on the outer wall of the tube body along the length direction of the tube body, the inner tube wall of the rib tube is fused with the outer wall of the tube body, and the interior of the rib tube is hollow, characterized in that: the rib tube comprises an outer tube layer and an inner tube layer, the outer tube layer is coated on the outside of the inner tube layer and fused with the inner tube layer, the inner tube layer has a plurality of corrugated strips protruding inwardly and arranged side by side, the corrugated strips are perpendicular to the extension direction of the rib tube, and the cross section of the corrugated strips is trapezoidal or square.

[0006] In the above-mentioned reinforced pipe, the rib pipe is composed of an outer pipe layer and an inner pipe layer, and the inner pipe layer can play a supporting role. At the same time, since the inner pipe layer has a plurality of corrugated strips arranged side by side, and the corrugated strips are perpendicular to the extension direction of the rib pipe, and the cross-section of the corrugated strips is trapezoidal or square, the supporting force of the corrugated strips on the rib pipe can be further improved, thereby effectively enhancing the strength, compression resistance and earthquake resistance of the entire reinforced pipe, so that after the reinforced pipe is buried underground, the rib pipe is not easy to deform, and even if it is affected by ground vibration, it is not easy to break due to vibration.

[0007] Between the rib tube and the tube body, when the tube body and the rib tube are extruded separately, the rib tube can be wrapped around the outside of the tube body, and a certain pressure is applied and the residual heat is used to weld the tube body and the rib tube together.

[0008] The above inner and outer directions are determined according to the axis of the pipe body. The position close to the axis of the pipe body is the inner side, and the position far from the axis of the pipe body is the outer side.

[0009] In a preferred solution, the inner pipe layer is a corrugated pipe. The inner pipe layer can directly adopt a corrugated pipe. The corrugated strips are the corrugations in the corrugated pipe.

[0010] In another preferred solution, the inner pipe layer is formed by folding a corrugated board, and the part that protrudes inward after the corrugated board is folded forms the corrugated strip.

[0011] In a further preferred solution, the corrugated board is provided with undulations arranged along the length direction, and the undulations gradually decrease from the middle to both sides. When the corrugated board is folded, it is folded along the width direction, and both sides are welded together. With this setting of the corrugated board, it can be smoothly folded and welded, and it is convenient for the subsequent formation of the ribbed pipe and the welding of the ribbed pipe to the pipe body; at the same time, after the corrugated board forms the inner pipe layer, the protruding positions in each undulation can form corrugated strips that gradually decrease towards the weld seam.

[0012] In a preferred solution, the longitudinal section of the ribbed pipe is trapezoidal or square. Generally, when the longitudinal section of the ribbed pipe is trapezoidal, the cross-section of the corrugated strip also corresponds to a trapezoid; when the longitudinal section of the ribbed pipe is square, the cross-section of the corrugated strip also corresponds to a square. These two shapes can make the ribbed pipe have stronger compressive resistance.

[0013] The beneficial effects of the present utility model are as follows: This enhanced pipe has better compressive and seismic resistance, and is not easily deformed after being buried, nor is it easily fractured due to vibration. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0021] Embodiment 1

[0022] As Figures 1-3 shown, a kind of reinforcing pipe includes a pipe body 1 and a ribbed pipe 2. The ribbed pipe 2 is spirally wound around the outer wall of the pipe body 1 along the length direction of the pipe body 1. The inner wall of the ribbed pipe 2 is welded to the outer wall of the pipe body 1, and the inside of the ribbed pipe 2 is hollow. The ribbed pipe 2 includes an outer pipe layer 201 and an inner pipe layer 202. The outer pipe layer 201 is wrapped outside the inner pipe layer 202 and welded to the inner pipe layer 202. The inner pipe layer 202 has a plurality of inwardly protruding and side-by-side corrugated strips 2021. The corrugated strips 2021 are perpendicular to the extending direction of the ribbed pipe 2. The cross-section of the corrugated strip 2021 and the longitudinal section of the ribbed pipe 2 are both trapezoidal.

[0023] In the above-mentioned reinforcing pipe, the ribbed pipe 2 is composed of an outer pipe layer 201 and an inner pipe layer 202. The inner pipe layer 202 can play a supporting role. At the same time, since the inner pipe layer 202 has a plurality of side-by-side corrugated strips 2021, and the corrugated strips 2021 are perpendicular to the extending direction of the ribbed pipe 2, and the cross-section of the corrugated strip 2021 is trapezoidal or square, therefore, the supporting force of the corrugated strip 2021 on the ribbed pipe 2 can be further improved, thereby effectively enhancing the strength, compressive resistance and seismic resistance of the entire reinforcing pipe. After the reinforcing pipe is buried underground, the ribbed pipe 2 is not easily deformed and is not easily broken due to vibration even under the influence of ground vibration.

[0024] Between the above-mentioned ribbed pipe 2 and the pipe body 1, when the pipe body 1 and the ribbed pipe 2 are extruded respectively, the ribbed pipe 2 can be wound around the outside of the pipe body 1, and a certain pressure is applied and the pipe body 1 and the ribbed pipe 2 are welded together by using the remaining heat.

[0025] The above-mentioned inner and outer directions are determined according to the axis of the pipe body 1. The position close to the axis of the pipe body 1 is the inner, and the position far from the axis of the pipe body 1 is the outer.

[0026] The inner pipe layer 202 is a corrugated pipe. The inner pipe layer 202 can directly adopt a corrugated pipe.

[0027] Embodiment 2

[0028] The difference between this embodiment and Embodiment 1 is that: as Figures 4-6 shown, the inner pipe layer 202' is formed by folding a corrugated sheet 3', and the inwardly protruding part after folding the corrugated sheet 3' forms a corrugated strip 2021'.

[0029] The corrugated sheet 3' is provided with a wavy undulation 301' arranged along the length direction, and the wavy undulation 301' gradually decreases from the middle to both sides. When the corrugated sheet 3' is folded, it is folded along the width direction, and both sides are welded together. With this setting, the corrugated sheet 3' can be folded and welded smoothly, and it is convenient for the subsequent formation of the rib tube 2' and the welding of the rib tube 2' to the tube body 1'; at the same time, after the inner tube layer 202' is formed on the corrugated sheet 3', the position of the protrusion in each undulation can form a corrugated strip 2021' that gradually decreases towards the weld seam 302'.

[0030] Example 3

[0031] The difference between this example and Example 1 is that: the cross-section of the corrugated strip and the longitudinal section of the rib tube are both square.

[0032] Example 4

[0033] The difference between this example and Example 2 is that: the cross-section of the corrugated strip and the longitudinal section of the rib tube are both square.
