[0033] Furthermore, the diameter of the middle tube groove 101 is consistent with the diameter of the inner cavity 300;

[0034] The second filling slots 103 are distributed in a linear array outside the middle tube slot 101, and the closer the second filling slots 103 are to the end of the middle tube slot 101, the smaller the diameter;

[0035] Preferably, four second filling slots 103 are provided, and thus four second filling ports 301 corresponding to the second filling slots 103 are also provided on the inner cavity 300 . On the same plane, the four second filling ports 301 are distributed in a circular array on the inner cavity 300 .

[0036] The first filling slots 102 have a trapezoidal cross section, and a plurality of first filling slots 102 are distributed in a ring array on the bottom surface of the filling shell 100 , and a positioning slot 104 is provided between every two first filling slots 102 ;

[0037] A pre-embedded layer 500 is disposed below the filling shell 100 .

[0038] Preferably, the material of the embedded layer 500 is cement, which is a embedded cement layer.

[0039] Furthermore, the interior of the column 200 is connected, and the interior of the column 200 is provided with an inner cavity 300;

[0040] The cross section of the first filling ports 201 is also trapezoidal, and a positioning head 202 is disposed between every two first filling ports 201 .

[0041] Furthermore, a stress steel plate 303 is provided at one end of the inner cavity 300 , and a lower sealing plate 302 is provided at the other end.
