Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] See also Figure 1-4 A high-bearing capacity concrete pipe pile in this embodiment includes a lower pipe pile 1, an upper pipe pile 2, a conical mounting seat 3 and a bearing reinforcement mechanism installed between the lower pipe pile 1 and the upper pipe pile 2.
[0032] The upper pipe pile 2 is movably mounted on the top of the lower pipe pile 1 , and the conical mounting seat 3 is fixedly mounted on the bottom of the lower pipe pile 1 .
[0033] The load-bearing reinforcement mechanism includes four reinforcement support rods 4 fixedly mounted on the outer peripheral wall of the conical mounting seat 3. The reinforcement support rods 4 include a rod body and a conical head. The reinforcement support rods 4 are installed at a downward inclination angle, and the conical head is installed at the bottom of the rod body. By inserting the reinforcement support rods 4 into the ground, the stability of the lower pipe pile 1 installed inside the ground is improved, thereby improving the bearing capacity.
[0034] See also Figure 1 The load-bearing reinforcement mechanism also includes a mounting ring 5 fixedly mounted on the inner circumferential wall of the upper pipe pile 2, two mounting rods 6 fixedly mounted on the bottom of the mounting ring 5, and a connecting pile 7 fixedly mounted on the bottom of the mounting rod 6. The diameter of the connecting pile 7 is the same as the inner diameter of the lower pipe pile 1. The connecting pile 7 is slidably mounted on the inner circumferential wall of the lower pipe pile 1. The inner diameter of the connecting pile 7 is the same as the inner diameter of the mounting ring 5, thereby improving the stability of the connection between the lower pipe pile 1 and the upper pipe pile 2.
[0035] Four reinforcement rods 8 are fixedly installed at the bottom of the upper pipe pile 2, and four reinforcement slots 15 are opened on the top of the lower pipe pile 1. The reinforcement rods 8 are inserted into the reinforcement slots 15 and are of suitable size, which is convenient for positioning and installing the reinforcement rods 8, thereby improving the stability and bearing capacity between the lower pipe pile 1 and the upper pipe pile 2.
[0036] The load-bearing reinforcement mechanism also includes two arc-shaped reinforcement connecting plates 9 movably installed on the outer peripheral walls of the lower pipe pile 1 and the upper pipe pile 2. The outer peripheral walls of the lower pipe pile 1 and the upper pipe pile 2 are each provided with two reinforcement positioning grooves 16. The reinforcement positioning seat 10 is clamped in the interior of the reinforcement positioning groove 16 and is adapted in size, so as to facilitate the clamping and installation of the arc-shaped reinforcement connecting plates 9 on the outer peripheral walls of the lower pipe pile 1 and the upper pipe pile 2.

High-strength fastening screws 12 pass through the internal threads of the mounting seats 11 and are connected to the inside of the thread grooves 17 and are of matching size, so as to facilitate fixing the arc-shaped reinforcement connecting plate 9 to the outer peripheral walls of the lower pipe pile 1 and the upper pipe pile 2, thereby improving the stability and bearing capacity of the connection between the lower pipe pile 1 and the upper pipe pile 2.
[0038] See also Figure 1-3 The load-bearing reinforcement mechanism also includes a high-strength fastening screw 12 movably installed inside the mounting seat 11, two I-shaped reinforcement frames 13 slidably connected to the inside of the two arc-shaped reinforcement connecting plates 9, and a push plate 14 fixedly installed on the top of the I-shaped reinforcement frame 13. T-shaped slots 18 are provided at both ends of the arc-shaped reinforcement connecting plate 9. The I-shaped reinforcement frame 13 is slidably connected to the inside of the T-shaped slot 18 and is of a suitable size.

The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.
[0042] The working principle of the above embodiment is:
[0043] First, the bottom of the lower pipe pile 1 and the conical mounting seat 3 are driven into the ground, and then the upper pipe pile 2 is moved to the top of the lower pipe pile 1 by the crane, and then the upper pipe pile 2 is moved downward to make the connecting pile 7 slide to the inner wall of the lower pipe pile 1, and at the same time, the reinforcing clamping rod 8 will be stuck in the interior of the lower pipe pile 1. At this time, the staff will fit the arc-shaped reinforcing connecting plate 9 to the outer wall of the lower pipe pile 1 and the upper pipe pile 2. At the same time, the reinforcing positioning seat 10 will be stuck in the reinforcing positioning groove 16 opened in the lower pipe pile 1 and the upper pipe pile 2. Then, four high-strength fastening screws 12 are passed through the interior of the mounting seat 11 and are threadedly connected to the top and bottom of the arc-shaped reinforcing connecting plate 9 respectively, and finally the I-shaped reinforcement frame 13 is slid from top to bottom to the interior of the arc-shaped reinforcement connecting plate 9. At this time, the positioning and installation work between the lower pipe pile 1 and the upper pipe pile 2 is completed, which improves the stability and bearing capacity of the connection between the lower pipe pile 1 and the upper pipe pile 2.
