[0009] By adopting the above technical solution, the first lifting hole is opened on the main board and is reinforced by the first reinforcing rib, so that the strength of the overall outer lifting ear is improved and the occurrence of breakage during the lifting process is reduced.

[0010] Preferably, first reinforcing plates are installed on both sides of the main board and at positions corresponding to the first hanging holes, and the first reinforcing plates are provided with first openings connected to the first hanging holes.

[0011] By adopting the above technical solution, the first reinforcing plate thickens the main board at the position corresponding to the first hanging hole, thereby improving the strength of the hanging position.

[0012] Preferably, reinforcement plates are fixedly installed on both sides of the main board, and connecting screws are preset on the pile barrel composite structure basis. The connecting screws are passed through the reinforcement plates, and connecting nuts are threadedly installed on the connecting screws.

[0015] By adopting the above technical solution, the second hanging hole is directly opened on the second reinforcing rib plate, and the second reinforcing rib plate is in a right-angle trapezoid shape, thereby improving the overall stability.

[0016] Preferably, a second reinforcing plate is installed at a position of the second reinforcing rib corresponding to the second hanging hole, and the second reinforcing plate is provided with a second opening connected to the second hanging hole.

[0017] By adopting the above technical solution, the second reinforcing plate makes the second reinforcing rib plate thicker at the position corresponding to the second lifting hole, thereby improving the strength of the lifting position.

[0018] Preferably, spare hooks are provided between adjacent inner lifting ears.

[0019] By adopting the above technical solution, when special circumstances arise during the lifting process and the lifting stability needs to be enhanced, the lifting can be directly carried out through the spare hook, thereby improving practicality.

[0021] By adopting the above technical solution, not only can the overall lifting strength meet the lifting requirements of the pile-bucket composite structure foundation, but the overall cost can also be reduced.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When the pile-bucket composite structure foundation is hoisted, each hoisting rope is connected to the corresponding outer hoisting lug or inner hoisting lug respectively, so that after all connections are completed, an angle is formed between the hoisting ropes on a corresponding outer hoisting lug and an inner hoisting lug. The stability of the triangle greatly improves the hoisting stability of the pile-bucket composite structure foundation;

[0024] 2. First stabilize the mainboard at the corresponding position of the pile bucket composite structure foundation, and then perform welding; after welding, the overall stability can also be improved;

The first reinforcing plates 13 are provided with a first opening 131 connected to the first hanging holes 111, so that the main board 11 is thickened at positions corresponding to the first hanging holes 111 to improve the overall strength.
