Because the main material of the upper pipe pile body 100 is reinforced concrete, the mass is large, and the eccentric rotation or shaking is unavoidable during rotation, and the clamping and even the thread damage are easily caused during the rotation and screwing between the arc-shaped blocks 300. The arc-shaped block 300 is arranged to be slidable and buffered by the elastic piece 211, so that the situation that threads are blocked and damaged during installation is effectively avoided, and the connection reliability is effectively ensured. Meanwhile, the welding step is omitted, and the butt joint efficiency is improved.

Referring to fig. 2 to 7, it can be understood that the elastic member 211 is a spring, the spring is sleeved outside a cylinder formed by a plurality of arc blocks 300, and the elastic member 211 can be a spring formed integrally and wound into a plurality of circles, or a plurality of springs wound into a single circle.

Referring to fig. 3 to 8, it can be understood that the inner diameter of the cylinder formed by the plurality of arc blocks 300 is smaller than the outer diameter of the insert pin 410. After the inserted link 410 is screwed into the cylinder formed by the plurality of arc blocks 300, the elastic member 211 can push the arc blocks 300 to press the inserted link 410, so that the threads on the inner side of the arc blocks 300 and the threads on the side wall of the inserted link 410 can be tightly engaged, and the inserted link 410 is fixed in the cylinder formed by the plurality of arc blocks 300, thereby abutting the upper pipe pile body 100 with the lower pipe pile body 200.

Referring to fig. 1 to 9, it can be understood that the lower end of the insert pin 410 is provided with a chamfer, and the inner side of the upper end of the arc block 300 is also provided with a chamfer, so that the insert pin 410 can be accurately rotatably inserted into the cylinder formed by the arc blocks 300 through the guiding effect of the chamfer due to possible errors when the insert pin 410 is aligned with the cylinder formed by the arc blocks 300 in the vertical direction, thereby effectively improving the installation speed and locking the docking time.

Referring to fig. 1 to 9, it can be understood that 3 guide grooves 212 are symmetrically formed in the groove 210, and the extending direction of the guide grooves 212 is the radial direction of the lower tubular pile body 200.
