Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete irregular-shaped pipe pile technology, specifically a composite reinforced prestressed concrete irregular-shaped pipe pile. Background Technology
[0002] Concrete irregular-shaped pipe piles generally include ordinary reinforced concrete and prestressed concrete. However, the obvious disadvantages of ordinary concrete pipe piles are their poor crack resistance, low stiffness, poor deformation performance, and limited application range. Therefore, prestressed concrete is widely used in the foundation engineering of hydraulic structures, industrial buildings, civil buildings, and bridges. However, existing composite reinforced prestressed concrete irregular-shaped pipe piles still have some disadvantages. For example, they do not have a protective function when used and transported over short distances. If a collision occurs, it is easy to cause damage or even cracking, which will render them unusable. At the same time, their overall structural strength is low. Therefore, we propose a composite reinforced prestressed concrete irregular-shaped pipe pile. Utility Model Content
[0003] The purpose of this utility model is to provide a composite reinforced prestressed concrete irregular pipe pile to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A composite reinforced prestressed concrete irregular pipe pile includes a concrete pile body, end caps on both the left and right sides of the concrete pile body, multiple sets of prestressed steel reinforcement hoops on the ends of the end caps away from the concrete pile body, multiple sets of transverse ribs evenly spaced around the outer wall of the concrete pile body, a rigid rubber layer on the ends of the transverse ribs away from the concrete pile body, a centrally reinforced concrete pile transversely arranged at the center of the inner cavity of the concrete pile body, internal prestressed steel reinforcements evenly spaced around the outer wall of the centrally reinforced concrete pile, reinforcing ribs connected together at the ends of the internal prestressed steel reinforcements away from the centrally reinforced concrete pile, and the reinforcing ribs are located at the center between the outer wall of the centrally reinforced concrete pile and the inner wall of the concrete pile body, external prestressed steel reinforcements evenly spaced around the outer wall of the reinforcing ribs.
[0006] Furthermore: the inner cavity of the rigid rubber layer is set as a hollow cavity, and screws are set at the top periphery of the rigid rubber layer and the transverse ridges away from the concrete pile body at the far end.
[0007] Furthermore: the internal prestressed steel bars and the external prestressed steel bars are staggered, and both the internal and external prestressed steel bars are fixedly welded to the reinforcing rib ring.
[0008] Furthermore, multiple sets of prestressed steel reinforcement hoops are arranged in a rectangular array at the end of the end cap away from the concrete pile body.
[0009] Furthermore: the concrete pile body, the reinforcing ring, and the central reinforced concrete pile are concentrically arranged.
[0010] Furthermore, the length of the transverse ridges from left to right is greater than four-fifths of the length of the concrete pile body from left to right.
[0011] Furthermore, the outer perimeter of all transverse convex ribs is designed as a sloping edge.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This composite reinforced prestressed concrete irregular-shaped pipe pile first has transverse ribs evenly spaced on the outer periphery of the concrete pile body, which provides initial reinforcement. Inside the concrete pile body, from the inside out, are arranged a central reinforced concrete pile, internal prestressed steel bars and reinforcing rings, and external prestressed steel bars. These four structures effectively increase the overall structural strength of the concrete irregular-shaped pipe pile, making it more stable and extending its service life. A rigid rubber layer is installed at the end of each transverse rib away from the concrete pile body. This rigid rubber layer provides effective cushioning protection. During handling and short-distance transportation, if a collision occurs, the rigid rubber layer effectively cushions the concrete pile body, preventing direct impact that could lead to damage or cracking.

[0017] 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.
[0018] Example 1:
[0019] Please see Figure 1-2This utility model provides a technical solution: a composite reinforced prestressed concrete irregular pipe pile, including a concrete pile body 1, end caps 2 on both the left and right sides of the concrete pile body 1, and multiple sets of prestressed steel reinforcement hoops 3 at the ends of the end caps 2 away from the concrete pile body 1. The above-mentioned contents are all common prior art in this field, and therefore will not be described in detail here. Multiple sets of transverse ribs 4 are equidistantly arranged around the outer wall of the concrete pile body 1. The transverse ribs 4 not only increase the overall structural strength but also increase friction. A hard rubber layer 5 is provided at the ends of the transverse ribs 4 away from the concrete pile body 1. The hard rubber layer 5 can play a buffering and protective role, preventing damage during transportation. In the event of a collision, the concrete pile body 1 can be effectively protected. A centrally reinforced concrete pile 6 is horizontally arranged at the center of the inner cavity of the concrete pile body 1. The outer wall of the centrally reinforced concrete pile 6 is surrounded by internal prestressed steel bars 7 at equal intervals. The end of the internal prestressed steel bars 7 away from the centrally reinforced concrete pile 6 is connected to a reinforcing ring 8, and the reinforcing ring 8 is located at the center between the outer wall of the centrally reinforced concrete pile 6 and the inner wall of the concrete pile body 1. The outer wall of the reinforcing ring 8 is surrounded by external prestressed steel bars 9 at equal intervals. The centrally reinforced concrete pile 6, the internal prestressed steel bars 7, the reinforcing ring 8 and the external prestressed steel bars 9 can effectively increase the overall strength of the concrete irregular pipe pile.
[0020] Preferably, the inner cavity of the rigid rubber layer 5 is set as a hollow cavity, which can increase the buffer protection effect. Screws are provided on the top periphery of the rigid rubber layer 5 and the end of the transverse rib 4 away from the concrete pile body 1. The rigid rubber layer 5 can be stably installed on the transverse rib 4 by means of screws.
[0021] Preferably, the internal prestressed steel bars 7 and the external prestressed steel bars 9 are staggered. The staggered arrangement can reduce the number of internal prestressed steel bars 7 and external prestressed steel bars 9 without affecting the overall performance. Both the internal prestressed steel bars 7 and the external prestressed steel bars 9 are fixedly welded to the reinforcing ring 8. Welding can increase the stability of the connection between the internal prestressed steel bars 7 and the external prestressed steel bars 9 and the reinforcing ring 8.
[0022] Preferably, multiple sets of prestressed steel reinforcement hoops 3 are arranged in a rectangular array at the end of the end cap 2 away from the concrete pile body 1. This arrangement facilitates the connection and installation of the end cap 2.
[0023] Example 2:
[0024] Reference Figure 1-2This embodiment differs from the first embodiment in that: the concrete pile body 1, the reinforcing ring 8, and the central reinforced concrete pile 6 are concentrically arranged; the length of the transverse ribs 4 from left to right is greater than four-fifths of the length of the concrete pile body 1 from left to right, which can increase the external structural strength of the overall concrete irregular pipe pile; the outer periphery of the transverse ribs 4 is set as a sloping edge, which can increase the external contact area and thus increase the friction.
[0025] All electrical appliances mentioned in this article are connected to an external power source via wires.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
