[0026] It should be noted that by utilizing two engineering piles 1 on the already cast engineering foundation and subsequently adding two bored piles 2 distributed side by side, the cast concrete casting layer 3 is cast as one with the engineering foundation, which not only meets the bearing capacity requirements of the tower crane for the foundation, but also reduces the number of bored piles. The concrete casting layer 3 is combined with the already cast engineering foundation, which also reduces the construction area of ​​the concrete casting layer 3.

[0027] In the embodiments of the present invention, please refer to Figure 1 , Figure 3 and Figure 4The pile heads of the engineering pile 1 and the cast-in-place pile 2 extend out of the casting layer and are both provided with a central joint assembly 4, the central joint assembly 4 comprising a sleeve pipe 41, a plurality of connecting plates 42 distributed in an annular manner and used for connecting to the foundation are fixedly installed at the bottom of the sleeve pipe 41, and a plurality of mounting holes 42a are provided on the connecting plate 42 and fixedly connected to the ground through long screws, and a fixing plate 43 is fixedly installed on the top of the sleeve pipe 41, a standard joint column 44 for connecting the standard section of the tower crane is fixedly welded on the fixing plate 43, and a bolt hole 44a is provided on the standard joint column 44, two side seats 45 distributed at 90° are fixedly welded on the side wall of the sleeve pipe 41, and a carrying groove 45a is provided on the side seat 45, and side holes 45b are provided on both side walls of the carrying groove 45a, and a reinforcing steel plate 5 is also installed between adjacent sleeve pipes 41;

[0029] It should be noted that after the engineering piles 1 and the bored piles 2 are set up, the middle link assembly 4 is installed in turn. Specifically, the sleeve 41 is sleeved on the pile head extending out of the foundation surface, and then the long screws are passed through the mounting holes 42a opened in the connecting plate 42 to fix it to the foundation (the connecting plate 42 on the engineering pile 1 is fixed on the already cast engineering foundation, and the connecting plate 42 on the bored pile 2 is fixed on the later cast concrete casting layer 3). The side seats 45 on the adjacent pile bodies are kept relatively arranged, and the reinforcing steel plates 5 are installed on the side seats 45 on the adjacent pile bodies by bolts.
