Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite pipe technology, and in particular to a PEPRP porous reinforced composite pipe. Background Technology
[0002] In the field of modern pipeline engineering, PEPRP porous reinforced composite pipe uses polyethylene as the base material and combines it with reinforced polypropylene reinforcement structure. Through composite process, it forms a new type of pipe with multiple advantages and is mainly used in municipal construction and water conservancy irrigation.
[0003] However, traditional PEPRP porous reinforced composite pipes suffer from long-term and large-volume soil compression after backfilling construction, which causes the hollow ribs to collapse under pressure, thereby reducing the reinforcing effect of the reinforcing ribs on the pipe. For example, during the rainy season, the moisture content of the backfill soil increases due to rainwater infiltration, which increases the soil's self-weight and lateral pressure. This causes the hollow ribs of the composite pipe in this section to be crushed, and cracks appear at the corners where the rib walls connect to the main body of the pipe. In some areas, the cavity structure completely loses its supporting function, resulting in obvious radial depressions. Utility Model Content
[0004] This utility model discloses a PEPRP porous reinforced composite pipe, which aims to solve the technical problem that in traditional PEPRP porous reinforced composite pipes, the reinforcing bars may be squeezed by the soil and tilt during construction such as backfilling, affecting the ring stiffness of the wound pipe and thus reducing the reinforcing effect of the reinforcing bars on the pipe.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A PEPRP porous reinforced composite pipe includes a pipe and further includes: a support mechanism: the support mechanism includes reinforcing ribs disposed on the outer wall of the pipe, vertical ribs fixed inside the reinforcing ribs, support strips connected to the outer walls on both sides of the vertical ribs, a plurality of equally spaced through holes on one side of the outer wall of the vertical ribs, and two symmetrically distributed cavities inside the reinforcing ribs; and a connection mechanism: the connection mechanism is located on one side of the outer wall of the reinforcing ribs.
[0006] By adopting the above technical solution, the support mechanism includes reinforcing ribs set on the outer wall of the pipe. The reinforcing ribs are used to improve the overall structural strength of the pipe. At this time, vertical ribs fixedly connected inside the reinforcing ribs provide longitudinal stiffness for the reinforcing ribs. At the same time, support bars are connected to the outer walls on both sides of the vertical ribs. The support bars can transfer the force borne by the vertical ribs to the cavity, thereby dispersing local stress. At this time, multiple equally spaced through holes are opened on one side of the outer wall of the vertical ribs to reduce the weight of the vertical ribs themselves. At the same time, stress is released when under force to avoid stress concentration. At this time, two symmetrically distributed cavities are provided inside the reinforcing ribs. The cavities can reduce the overall weight while ensuring the structural strength of the reinforcing ribs, and can buffer external pressure through their own deformation.
[0007] As a further embodiment of this utility model: the connecting mechanism includes a connecting plate connected to the outer wall of one side of the reinforcing rib, a plurality of teeth are equidistantly connected to the outer wall of the connecting plate away from the reinforcing rib, a plurality of protrusions are equidistantly connected to the outer wall of the teeth, two connecting strips are symmetrically connected to one side of the outer wall of the connecting plate, and a plurality of fixing strips are connected between the two supporting strips.
[0008] By adopting the above technical solution, the connecting mechanism includes a connecting plate connected to the outer wall of one side of the reinforcing rib. The connecting plate is used to connect the reinforcing rib and the pipe together. At this time, multiple teeth connected to the outer wall of one side of the connecting plate increase the contact area between the connecting plate and the pipe, thereby improving the connection stability. At this time, multiple equidistant protrusions connected to the outer wall of the teeth enhance the friction between the teeth and the pipe, thereby preventing relative slippage. At the same time, two connecting strips connected to the outer wall of one side of the connecting plate help fix the position of the connecting plate and enhance the overall rigidity of the connecting mechanism. At this time, multiple fixing strips are connected between the two support strips. The fixing strips can strengthen the connection strength between the support strips and improve the stability of the support structure.
[0009] In summary, this application includes at least one of the following beneficial technical effects: 1. Improve the compressive stability of the reinforcing ribs. The vertical ribs provide longitudinal stiffness as the core support, and the support bars on both sides transfer the force to the cavity to achieve local stress dispersion. The through holes on the vertical ribs release stress while reducing weight and avoid stress concentration. With the help of the symmetrically distributed cavities inside the reinforcing ribs, the weight is reduced while ensuring structural strength, and the external pressure is buffered by its own deformation, thereby improving the compressive stability of the reinforcing ribs and effectively resisting external compressive loads.
[0010] 2. Improve the connection stability between the pipe and the reinforcing rib. A stable connection between the reinforcing rib and the pipe is achieved through a connecting plate. At this time, multiple teeth are used to increase the contact area and improve the connection stability. The convex strips on the outer wall of the teeth enhance the friction and prevent relative slippage. Then, two connecting strips are used to help fix the position of the connecting plate to enhance the overall rigidity. Finally, the fixing strips between the support strips are used to strengthen the stability of the support structure, thereby improving the connection stability between the pipe and the reinforcing rib and effectively preventing the connection from loosening or separating.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Reference Figure 1 and Figure 2 A PEPRP porous reinforced composite pipe includes a pipe 1 and further includes: a support mechanism: the support mechanism includes reinforcing ribs 2 disposed on the outer wall of the pipe 1, vertical ribs 11 fixed inside the reinforcing ribs 2, support strips 4 connected to the outer walls on both sides of the vertical ribs 11, a plurality of through holes 5 evenly distributed on one side of the outer wall of the vertical ribs 11, and two symmetrically distributed cavities 3 inside the reinforcing ribs 2; a connection mechanism: the connection mechanism is located on one side of the outer wall of the reinforcing ribs 2.
[0018] Specifically, the support mechanism includes reinforcing ribs 2 set on the outer wall of the pipe 1. The reinforcing ribs 2 are used to improve the overall structural strength of the pipe 1. At this time, the vertical ribs 11 fixedly connected inside the reinforcing ribs 2 provide longitudinal stiffness for the reinforcing ribs 2. At the same time, the outer walls on both sides of the vertical ribs 11 are connected to support bars 4. The support bars 4 can transfer the force borne by the vertical ribs 11 to the cavity 3, thereby dispersing local stress. At this time, the weight of the vertical ribs 11 is reduced by multiple equally spaced through holes 5 opened on one side of the outer wall of the vertical ribs 11. At the same time, stress is released when under force to avoid stress concentration. At this time, the reinforcing ribs 2 are provided with two symmetrically distributed cavities 3. The cavities 3 can reduce the overall weight while ensuring the structural strength of the reinforcing ribs 2, and can buffer external pressure through their own deformation.
[0019] Among them, the outer wall of the side of the multiple support bars 4 away from the vertical rib 11 is connected to the inner wall of the same cavity 3. By fixing the support bars 4 and the cavity 3 together, the pressure transmission efficiency of the reinforcing rib 2 is improved.
[0020] Specifically, the outer walls of the vertical rib 11 are at a gradually decreasing angle of 60 degrees. The vertical rib 11 with the gradually decreasing angle of 60 degrees is used to reduce the compressive stress on the reinforcing rib 2.
[0021] Reference Figure 2 and Figure 3 In a preferred embodiment, the connecting mechanism includes a connecting plate 6 connected to the outer wall of one side of the reinforcing rib 2. A plurality of teeth 8 are connected at equal intervals on the outer wall of the connecting plate 6 away from the reinforcing rib 2. A plurality of protrusions 10 are connected at equal intervals on the outer wall of the teeth 8. Two connecting strips 9 are symmetrically connected to one side of the outer wall of the connecting plate 6. A plurality of fixing strips 7 are connected between the two supporting strips 4.
[0022] Specifically, the connecting mechanism includes a connecting plate 6 connected to the outer wall of one side of the reinforcing rib 2. The connecting plate 6 is used to connect the reinforcing rib 2 and the pipe 1 together. At this time, multiple teeth 8 connected to the outer wall of one side of the connecting plate 6 increase the contact area between the connecting plate 6 and the pipe 1, thereby improving the connection stability. At this time, multiple equidistant protrusions 10 connected to the outer wall of the teeth 8 enhance the friction between the teeth 8 and the pipe 1, thereby preventing relative slippage. At the same time, two connecting strips 9 connected to the outer wall of one side of the connecting plate 6 help fix the position of the connecting plate 6 and enhance the overall rigidity of the connecting mechanism. At this time, multiple fixing strips 7 are connected between the two support strips 4. The fixing strips 7 can strengthen the connection strength between the support strips 4 and improve the stability of the support structure.
[0023] The angle between the fixing strip 7 and the cavity 3 is 30 degrees, which is used to disperse the local extrusion pressure into surface contact force.
[0024] Specifically, multiple equally spaced teeth 8 are connected to the outer wall of the pipe 1 to improve the firmness of the connection between the connecting plate 6 and the pipe 1.
[0025] Reference Figure 1 and Figure 2 In a preferred embodiment, the reinforcing rib 2 has a spiral structure.
[0026] Specifically, by forming a continuous ring support along the outer wall of the pipe 1 with the reinforcing rib 2, the radial pressure on the pipe 1 is evenly distributed, thereby improving the overall ring stiffness of the pipe 1.
[0027] Working Principle: During use, the spiral reinforcing ribs 2 connected to the outer wall of the pipe 1 form a supporting frame, thereby evenly distributing the radial pressure on the pipe 1 along the spiral direction, thus improving the overall ring stiffness of the pipe 1. At this time, the vertical ribs 11 inside the reinforcing ribs 2 bear the longitudinal pressure, and the gradually decreasing 60-degree bevel angle on both sides of their outer walls can reduce the compressive stress between them and the surrounding structure. At this time, the longitudinal force is transmitted to the symmetrically distributed cavities 3 through the multiple support bars 4 connected to both sides of the vertical ribs 11. The multiple support bars 4 are all connected to the inner wall of the same cavity 3, thereby achieving the dispersion of local stress. At this time, the through holes 5 on the vertical ribs 11 reduce their own weight and can release stress through deformation when subjected to force, avoiding local damage caused by stress concentration. This improves the compressive stability of the reinforcing rib 2. Secondly, the reinforcing rib 2 is connected to the pipe 1 by the connecting plate 6. At this time, multiple teeth 8 on the outer wall of one side of the connecting plate 6 are embedded in the outer wall of the pipe 1, which increases the contact area and improves the connection stability. The multiple protrusions 10 connected to the outer wall of the teeth 8 enhance the friction between the tooth and the pipe 1, thereby effectively preventing relative sliding. At this time, the two connecting strips 9 on the connecting plate 6 are used for side fixation, which enhances the overall rigidity of the connection mechanism. The fixing strips 7 between the support strips 4 form a 30-degree angle with the cavity 3, which can disperse the local extrusion pressure into surface contact force, which strengthens the connection strength between the support strips 4 and improves the overall stability of the support structure.
