First, the pipe pile body is connected to the pile driving machine through a connecting component. The pile driving machine is started to apply downward pressure to the pipe pile body to carry out the pile driving work. By gradually tilting the third, second, and first gradually changing pile bodies at the bottom end of the pipe pile body, the soil can be diverted in sections to reduce the reaction force. At the same time, multiple pile driving cutters on the surface of the third gradually changing pile body can break hard soil or stone.

Description

Technical Field

[0001] This utility model relates to the field of concrete pipe pile technology, and in particular to a concrete pipe pile. Background Technology

[0002] Concrete pipe piles are precast hollow concrete components using centrifugal technology, characterized by high strength, high load-bearing capacity, and high construction efficiency. Standard sections are 10 meters long and 300–1200 mm in diameter, suitable for high-rise buildings, bridges, and other engineering projects.

[0003] When driving concrete pipe piles, pile driving machinery is needed to drive the concrete pipe piles into the foundation. However, the existing concrete pipe pile structure is relatively simple and lacks stress distribution mechanism and reinforcement mechanism. When the pressure on the concrete pipe pile is offset or too large, it is easy to cause problems such as cracking on the surface of the pipe pile, which greatly reduces the stability of the concrete pipe pile in use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a concrete pipe pile to solve the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A concrete pipe pile includes a pipe pile body, a first gradually changing pile body at the bottom end of the pipe pile body, a second gradually changing pile body at the bottom end of the first gradually changing pile body, a third gradually changing pile body at the bottom end of the second gradually changing pile body, a pile driving tool fixedly connected to the surface of the third gradually changing pile body, a pressure-distributing mechanism on the surface of the pipe pile body, a connecting component inside the pipe pile body, and a reinforcing mechanism inside the pipe pile body.

[0006] Preferably, the pressure-distributing mechanism consists of a pressure-distributing ring and a pressure-distributing plate. The inner wall of the pressure-distributing ring is fixedly connected to the surface of the pipe pile body, and the pressure-distributing plate is fixedly connected to the top surface of the pressure-distributing ring, with the inner wall of the pressure-distributing plate also fixedly connected to the surface of the pipe pile body.

[0007] Preferably, the connecting assembly consists of a steel reinforcement cage and a connecting hole, wherein the steel reinforcement cage is fixedly connected to the inner wall of the pipe pile body, and the connecting hole is opened through at the top of the pipe pile body.

[0008] Preferably, the reinforcing mechanism consists of a fixed ring, a reinforcing rod, and a reinforcing ring. The fixed ring is fixedly connected to the inner wall of the pipe pile body, the reinforcing rod is fixedly connected to the bottom surface of the fixed ring, the inner wall of the reinforcing ring is fixedly connected to the surface of the reinforcing rod, and the surface of the reinforcing ring is fixedly connected to the inner wall of the pipe pile body.

[0009] Preferably, there are multiple pressure-distributing plates, and all multiple pressure-distributing plates are located on the surface of the pipe pile body.

[0010] Preferably, the reinforcing ring is circular in shape and is made of metal.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This concrete pipe pile first connects the pipe pile body to the pile driving machinery through a connecting component. The pile driving machinery is then activated to apply downward pressure to the pipe pile body for pile driving. The gradually tilting of the third, second, and first gradually tilting pile bodies at the bottom of the pipe pile body allows for segmented distribution of soil, reducing reaction force. Simultaneously, multiple pile driving cutters on the surface of the third gradually tilting pile body break up hard soil or stone. The pressure-distributing mechanism evenly transmits stress, preventing damage to the pipe pile body. The reinforcing mechanism enhances the load-bearing strength of the pipe pile body during pile driving. This achieves the goal of facilitating uniform pressure distribution on the concrete pipe pile during the pile driving process, avoiding the problem of existing concrete pipe piles easily breaking due to excessive stress or displacement, thus greatly reducing their stability.

[0014] 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.

[0015] Example: Refer to Figure 1-3A concrete pipe pile includes a pipe pile body 1, a first gradually changing pile body 2 at the bottom end of the pipe pile body 1, a second gradually changing pile body 3 at the bottom end of the first gradually changing pile body 2, a third gradually changing pile body 4 at the bottom end of the second gradually changing pile body 3, a pile driving tool 5 fixedly connected to the surface of the third gradually changing pile body 4, a pressure-distributing mechanism on the surface of the pipe pile body 1, the pressure-distributing mechanism consisting of a pressure-distributing ring 6 and a pressure-distributing plate 7, the number of pressure-distributing plates 7 being multiple, and all the pressure-distributing plates 7 being located on the surface of the pipe pile body 1, used to transmit reaction force, improving the uniformity of pressure distribution, the inner wall of the pressure-distributing ring 6 being fixedly connected to the surface of the pipe pile body 1, the pressure-distributing plate 7 being fixedly connected to the top surface of the pressure-distributing ring 6, and the inner wall of the pressure-distributing plate 7 being fixedly connected to the surface of the pipe pile body 1, used to transmit stress, improving the stability of pile driving, a connecting component and a reinforcing mechanism are provided inside the pipe pile body 1.

[0016] Specifically, the connecting component consists of a steel reinforcement cage 8 and a connecting hole 9. The steel reinforcement cage 8 is fixedly connected to the inner wall of the pipe pile body 1, and the connecting hole 9 is opened through the top of the pipe pile body 1 for connecting the pile driving machinery, while improving the overall strength of the pipe pile body 1.

[0017] Specifically, the reinforcing mechanism consists of a fixed ring 10, a reinforcing rod 11, and a reinforcing ring 12. The reinforcing ring 12 is circular and made of metal. The metal reinforcing ring 12 has higher strength, is less prone to deformation and damage under stress, and is more durable. The fixed ring 10 is fixedly connected to the inner wall of the pipe pile body 1, the reinforcing rod 11 is fixedly connected to the bottom surface of the fixed ring 10, and the inner wall of the reinforcing ring 12 is fixedly connected to the surface of the reinforcing rod 11. The surface of the reinforcing ring 12 is also fixedly connected to the inner wall of the pipe pile body 1.

[0018] In use: First, connect the pipe pile body 1 to the pile driving machine through the connecting hole 9. Start the pile driving machine to apply downward pressure to the pipe pile body 1 for pile driving. Through the separate gradual tilt of the third gradual pile body 4, the second gradual pile body 3 and the first gradual pile body 2 set at the bottom of the pipe pile body 1, the soil can be divided and diverted in sections when the pipe pile body 1 enters the soil, so as to reduce the reaction force on the pipe pile body 1 during the pile driving. At the same time, through the multiple pile driving cutters 5 set on the surface of the third gradual pile body 4, hard soil or stone can be quickly crushed during the pile driving process. When the pressure dividing ring 6 is subjected to the reaction force, the pile driving stress can be evenly transmitted to the pipe pile body 1 through multiple pressure dividing plates 7 to avoid the problem of pressure deviation leading to damage to the pipe pile body 1. At the same time, through the reinforcing rod 11 and reinforcing ring 12 set inside the pipe pile body 1, the stress strength of the pipe pile body 1 during pile driving can be improved.

[0019] 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.
