The main weighing steel bar 7 penetrates through the inside of the limiting ring 9. The limiting ring 9 is circular and is located in the middle section of the main weighing steel bar 7.

[0023] The main function of placing the installation base 3 at the bottom of the foundation pit 2 is to make the bottom of the foundation pit 2 flat, so that the main weighing steel bar 7 can always remain vertical upward after installation. After pouring, the main weighing steel bars 7 will be evenly distributed inside the concrete, enabling the pile foundation after pouring to reach the maximum bearing capacity.

[0024] Among them, an installation hole 10 is opened inside the limit ring 9, an auxiliary steel bar 11 is inserted inside the installation hole 10, a connecting sleeve 12 is sleeved outside the auxiliary steel bar 11, and the auxiliary steel bar 11 is perpendicular to the main weighing steel bar 7.

[0025] The main function of the installation hole 10 is that after the installation is completed, the auxiliary steel bar 11 can be directly inserted into the installation hole 10, so as to achieve the effect of convenient installation, and at the same time, it also has a strong supporting effect on the horizontally poured concrete.

[0026] Among them, an installation sleeve 13 is sleeved outside the main weighing steel bar 7, a reinforcing steel bar 14 is fixedly installed on one side of the installation sleeve 13 away from the main weighing steel bar 7, a fixing sleeve 15 is sleeved outside the reinforcing steel bar 14, and a steel nail 16 is fixedly installed inside the fixing sleeve 15.

[0027] The steel nail 16 is fixedly installed with the ground 1. After the reinforcing steel bar 14 is sleeved outside the main weighing steel bar 7 through the installation sleeve 13 and the installation is completed, the angle of the reinforcing steel bar 14 is adjusted, so that the fixing sleeve 15 fixes the reinforcing steel bar 14 to prevent the situation of uneven force caused by deviation during pouring.

[0028] Among them, a card slot 17 is opened at the top end of the ground 1, a card block 18 is inserted inside the card slot 17, a baffle 19 is fixedly installed above the card block 18, and a sealing ring 20 is sleeved outside the baffle 19.

[0029] The connecting sleeve 12 is circular and is located at the junction of the baffle 19 and the ground 1. Its main function is to seal the junction of the baffle 19 and the ground 1 to prevent the concrete from flowing out through the gap during pouring.

[0030] Among them, a positioning hole 21 is opened inside the installation base 3. The positioning hole 21 is located at the center of the installation base 3. A fixing steel bar 22 is fixedly installed at the bottom of the installation base 3. There are multiple fixing steel bars 22, and all the multiple fixing steel bars 22 are conical.

[0031] The main function of the multiple fixing steel bars 22 is that after the installation base 3 is placed inside the ground 1, the multiple fixing steel bars 22 are inserted into the soil, so that the installation base 3 can be stably placed inside the foundation pit 2 and will not shake easily, ensuring the overall stability of the installation base 3 during installation and pouring.

[0032] Among them, a reinforcing groove 23 is opened inside the ground 1. The reinforcing groove 23 is located in the middle of the ground 1 and is outside the limit ring 9. The diameter of the reinforcing groove 23 is larger than the diameter value of the foundation pit 2 and the reinforcing groove 23 is coaxial with the foundation pit 2.

[0033] There are multiple auxiliary steel bars 11, and all of the multiple auxiliary steel bars 11 are located inside the reinforcement groove 23. When pouring is carried out after installation is completed, the interior of the reinforcement groove 23 will be filled with concrete. At the same time, the auxiliary steel bars 11 filled inside the reinforcement groove 23 will improve the overall firmness, so that when an earthquake or other situations occur, the pile foundation will not easily shake or collapse.

[0034] Among them, there are multiple sliding grooves 4 and multiple sliders 5. All of the multiple sliding grooves 4 and multiple sliders 5 are located inside the installation base 3, and the multiple sliding grooves 4 and multiple sliders 5 are evenly and equally angularly distributed inside the installation base 3.

[0035] The multiple sliders 5 make it convenient to install the positioning sleeve 6 above the installation base 3 through the sliding action with the multiple sliding grooves 4. Thus, when the main weighing steel bar 7 is installed, it has the effect of quick positioning. At the same time, the force generated by the main weighing steel bar 7 above the installation base 3 is more uniform.

[0036] Among them, there are multiple main weighing steel bars 7. All of the multiple main weighing steel bars 7 are located inside the foundation pit 2, and all of the multiple main weighing steel bars 7 pass through the inside of the limiting ring 9. There are multiple limiting sleeves 8, and the multiple limiting sleeves 8 are respectively sleeved above the multiple main weighing steel bars 7.

[0037] The main function of the multiple limiting sleeves 8 is to limit the limiting ring 9 to prevent the limiting ring 9 from possibly slipping down after installation is completed. At the same time, the multiple main weighing steel bars 7 are limited by the limiting ring 9, so that after pouring is completed, the force borne reaches the maximum, improving the pouring quality.

[0038] The working principle and usage process of the present utility model:

[0039] First, a foundation pit 2 is dug inside the ground 1, so that the diameter value of the foundation pit 2 is equal to that of the installation base 3.

At the same time, the fixing steel bars 22 are inserted into the bottom of the ground 1 to fix the installation base 3 and keep it stable. At this time, the auxiliary steel bars 11 are inserted into the installation holes 10 so that the auxiliary steel bars 11 are located inside the reinforcement grooves 23. Then, the installation sleeve 13 is sleeved on the outside of the main weighing steel bar 7 and above the limit ring 9, and then the fixing sleeve 15 is fixed by steel nails 16;

[0042] Finally, the baffle 19 is inserted into the card slot 17 through the card block 18, so that the bottom of the baffle 19 contacts the ground 1. At the same time, the sealing ring 20 is sleeved on the outside of the baffle 19 to achieve a sealing effect, and the overall installation of the device is completed. Finally, concrete is poured into the foundation pit 2 until it is poured into the baffle 19, thus completing the pouring of a pile foundation.
