The grouting auxiliary mechanism 6 is used to inject concrete into the concrete filling mechanism 5 and the plain concrete pile 1. Two position determining mechanisms 7 are arranged outside the plain concrete pile 1 and the reinforced concrete pile 3. The position determining mechanism 7 is used to predetermine the installation positions of the plain concrete pile 1 and the reinforced concrete pile 3. Under the action of the position determining mechanism 7, after the holes are drilled in the ground, the two plain concrete piles 1 are first placed in the multiple holes, and a hole is left between the two plain concrete piles 1. After the two plain concrete piles 1 are placed, the combined slide bars 4 on both sides are aligned with the combined slide grooves 2 on both sides, and then the reinforced concrete pile 3 is placed in the hole between the two plain concrete piles 1. At the same time, the combined slide bar 4 slides into the interior of the combined slide groove 2. At this time, the installation of the bite pile is completed.

[0018] In this embodiment, a concrete injection groove 501 is provided in the plain concrete pile 1, and a concrete filling mechanism 5 is used to be movably inserted in the concrete injection groove 501. The concrete filling mechanism 5 includes a movable plug 502, a hollow rod 505 and a fixed top plate 506. The concrete injection groove 501 provides a space for containing concrete. The top of the movable plug 502 is fixedly connected to the hollow rod 505. The movable plug 502 is connected to the inside of the hollow rod 505. The top of the hollow rod 505 is fixedly connected to the fixed top plate 506. The outer diameter of the fixed top plate 506 is greater than the outer diameter of the hollow rod 505. The hollow rod 505 plays a connecting role. The movable plug 502 can squeeze the unsolidified concrete in the concrete injection groove 501. The bottom of the movable plug 502 is provided with a fitting groove 503. The fitting groove 503 can provide a receiving position, and the fitting groove 503 is rotatably connected to a rotating sealing plate 504 inside, and the rotating sealing plate 504 can achieve a blocking effect. The fixed top plate 506 can provide an installation position, and a plurality of through holes 507 are provided inside the outer edge of the fixed top plate 506, and the through holes 507 can flow through concrete. A rotating groove 508 is provided inside the top of the fixed top plate 506, and a rotating plate 509 is rotatably connected inside the rotating groove 508. The rotating plate 509 can rotate inside the rotating groove 508. The top of the rotating plate 509 is fixedly connected to a combined blocking cylinder 510, and the combined blocking cylinder 510 can provide an installation position for the grouting auxiliary mechanism 6, and a plurality of connecting holes 510 are provided inside the bottom end of the combined blocking cylinder 510. 1. After the connecting hole 511 and the through hole 507 are aligned, concrete can be passed into the interior of the concrete injection groove 501. The interior of the plain concrete pile 1 is provided with a plurality of first splicing semicircular grooves 512 at the outer edge of the combined slide 2, and a plurality of second splicing semicircular grooves 514 are provided at the outer edge of the combined slide 4. The first splicing semicircular grooves 512 and the second splicing semicircular grooves 514 can form a cylindrical groove after cooperation. The lower part of the plain concrete pile 1 is provided with a plurality of outlet holes 513 on one side of the combined slide 2. The outlet holes 513 can connect the concrete injection groove 501 and the cylindrical groove. The outlet holes 513 are connected to the concrete injection groove 501. The connecting hole 511 is the same size as the through hole 507. After the bite pile is installed, The combined blocking cylinder 510 in the concrete injection groove 501 is pulled out upward, so that the rotating plate 509 can be used to drive the fixed top plate 506 to move upward, thereby driving the hollow rod 505 to move upward, and then driving the movable plug 502 to move upward. When the movable plug 502 moves to the inner top of the concrete injection groove 501, the rotating grouting auxiliary mechanism 6 drives the combined blocking cylinder 510 to rotate, thereby driving the connecting hole 511 to rotate, so that the connecting hole 511 and the through hole 507 on the fixed top plate 506 are staggered, and then concrete is injected into the grouting auxiliary mechanism 6. At this time, concrete will be injected into the interior of the hollow rod 505. Since the movable plug 502 moves to the inner top of the concrete injection groove 501,Therefore, the rotating sealing plate 504 rotates downward under the action of gravity, and the concrete injected into the hollow rod 505 is injected into the concrete injection groove 501 through the movable plug 502. When the concrete injection groove 501 is filled with concrete, the blocking cylinder 510 is pushed downward, thereby driving the hollow rod 505 to move downward and driving the movable plug 502 to move downward. After the rotating sealing plate 504 moves downward, the reaction force of the concrete inside the concrete injection groove 501 can force the rotating sealing plate 504 to rotate into the inside of the fitting groove 503, thereby blocking the bottom of the movable plug 502. At this time, after the hollow rod 505 moves downward, it can drive the movable plug 502 to move downward, and then the movable plug 502 can be used to squeeze the concrete from the concrete injection groove 501 into the outlet hole 51. 3, and enter the cylindrical groove composed of the first splicing semicircular groove 512 and the second splicing semicircular groove 514 through the outlet hole 513, and fill the gap between the combined slide groove 2 and the combined slide bar 4 with concrete, thereby increasing the sealing and stability of the splicing between the plain concrete pile 1 and the reinforced concrete pile 3, and then rotating the grouting auxiliary mechanism 6 so that the grouting auxiliary mechanism 6 drives the combined blocking cylinder 510 to rotate, so that the connecting hole 511 can be aligned with the through hole 507 on the fixed top plate 506. Since the hollow rod 505 is already filled with concrete, after injecting concrete into the grouting auxiliary mechanism 6, the concrete will enter the space between the fixed top plate 506, the hollow rod 505, the movable plug 502 and the concrete injection groove 501 through the connecting hole 511 and the through hole 507, thereby enhancing the strength of the plain concrete pile 1.
