[0021] Further, a connecting plate 9 is provided at one end of the concrete pile body 1 away from the pile cap 3, the top of the connecting plate 9 is located on the outside of the concrete pile body 1 and is fixedly connected to a second outer steel cylinder 10, the top of the connecting plate 9 is located on the inside of the concrete pile body 1 and is fixedly connected to a second inner steel cylinder 11, a circular plate 12 is provided on the side of the connecting plate 9 away from the pile cap 3, the top of the circular plate 12 is fixedly connected to a vertical rod 13, the vertical rod 13 is cooperatively connected to the second inner steel cylinder 11, the bottom of the circular plate 12 is equidistantly fixedly connected to an inclined plate 14, the sides of two adjacent inclined plates 14 close to each other are fixedly connected to a reinforcing plate 15, and the reinforcing plate 15 is fixedly connected to the circular plate 12;
[0022] In the specific implementation process, it is worth pointing out that, through the cooperation among the concrete pile body 1, the connecting plate 9, the second outer steel cylinder 10 and the second inner steel cylinder 11, and through the fixing between the second outer steel cylinder 10 and the second inner steel cylinder 11 inside and outside the bottom of the concrete pile body 1 and the concrete pile body 1, the concrete pile body 1 is strengthened at the pile tip position to prevent the concrete near the pile tip from being separated from the pile body after being broken. The pile tip of the concrete pile body 1 is made of metal material and is welded and fixed to the connecting plate 9 through the cooperation between the second outer steel cylinder 10 and the vertical rod 13. The stability between the high pile tip and the concrete pile body 1, the reinforcement plate 15 is used to improve the strength of the inclined plate 14, so that the inclined plate 14 can be stably rammed in, through the cooperation between the concrete pile body 1, the connecting plate 9, the second outer steel cylinder 10, the second inner steel cylinder 11, the circular plate 12, the vertical rod 13, the inclined plate 14 and the reinforcement plate 15, by stably fixing the pile tip of the metal material to the reinforced concrete pipe pile, the strength of the pile tip is strengthened, the ground-breaking ability of the reinforced concrete pipe pile is improved, and the friction between the pile tip of the reinforced concrete pipe pile and the soil is reduced, thereby reducing the number of tamping times on the reinforced concrete pipe pile and reducing the probability of damage to the pile cap;
[0023] Furthermore, the top of the connecting plate 9 is equidistantly fixedly connected with a fixing pipe 16, and the fixing pipe 16 is fixedly connected to the main reinforcement 2;
[0024] In the specific implementation process, it is worth pointing out that through the cooperation between the concrete pile body 1, the main reinforcement 2, the connecting plate 9 and the fixing pipe 16, the fixing pipe 16 is inserted into the main reinforcement 2 for fixing, thereby improving the connection stability between the concrete pile body 1 and the connecting plate 9;

[0026] In the specific implementation process, it is worth pointing out that through the cooperation between the main reinforcement 2, the outer stirrup 17 and the reinforcing rib 18, the position of the main reinforcement 2 is fixed by supporting and limiting the inside and outside of the main reinforcement 2 by the reinforcing rib 18 and the outer stirrup 17, so that the main reinforcement 2 forms a stable steel bar component, and at the same time, the development of cracks inside the concrete can be limited, and the bonding strength can be improved;

[0029] Specifically, when the reinforced reinforced concrete pipe pile structure is used, the pile driver lifts the reinforced concrete pipe pile and uses hydraulic power to accelerate the hammer head to hit the pile cap 3 of the reinforced concrete pipe pile. After the pile cap 3 is impacted, the impact force is transmitted to the concrete pile body 1, so that the pile tip of the reinforced concrete is inserted into the soil layer. During the pile driving process, the inclined plate 14 squeezes the soil to both sides so that the pipe pile can be rammed into the soil more smoothly. After the pile driver hammers the reinforced concrete pipe pile many times, the impact of the hammer head causes the concrete in contact with the pile cap 3 to break. The broken concrete is retained in the first outer steel cylinder 4 and the first inner steel cylinder 5 under the action of the prestressed steel wire 6, so as to prevent the formation of a gap at the bottom of the pile cap 3. At the same time, the first outer steel cylinder 4 and the first inner steel cylinder 5 are connected by the connecting rod 8. The fixing of the steel cylinder 5 can prevent the first outer steel cylinder 4 and the first inner steel cylinder 5 from being deformed, so that the crushed concrete can still transmit the impact force, thereby improving the strength and stability of the pile cap 3 of the reinforced concrete pipe pile, and preventing the pile cap 3 from being skewed after multiple hammering. Through the cooperation among the concrete pile body 1, the main reinforcement 2, the pile cap 3, the first outer steel cylinder 4, the first inner steel cylinder 5, the prestressed steel wire 6, the casing 7 and the connecting rod 8, the first outer steel cylinder 4 and the first inner steel cylinder 5 are arranged at the bottom of the pile cap 3 to form a coating on the top of the concrete pile body 1, thereby improving the impact resistance of the pile cap 3, preventing the concrete close to the pile cap 3 from being separated from the pile body after being crushed, and avoiding the formation of a gap between the bottom of the pile cap 3 and the concrete pile body 1, thereby enhancing the stability of the pile cap of the pipe pile, and ensuring the stable tamping of the reinforced concrete pipe pile.
