An inner conical cover 9 is provided inside the mouth of the outer conical cover 8, and a plurality of suction and discharge channels are formed between the outer surface of the inner conical cover 9 and the inner wall of the outer conical cover 8 through a plurality of distributed partitions 11. Each suction and discharge guide is communicated with the corresponding rectangular concave surface 910 on the outer surface of the inner conical cover 9;

[0024] When the mouth of the outer conical cover 8 is located inside the building concrete slurry, the second cylinder 3 is operated to be in a contracted state, and the piston 7 connected thereto moves along the suction and discharge pipe 6 from bottom to top, so that the building concrete slurry enters the space formed between the outer conical cover 8 and the inner conical cover 9 through the suction and discharge channels;

[0025] When the second cylinder 3 is in an orderly intermittent extended state, the piston 7 moves along the suction and discharge pipe 6 from top to bottom, so that the inhaled building concrete slurry is squeezed and discharged to the front of the rectangular concave surface 910;

[0037] Furthermore, the universal wheel 4 is in rolling contact with the external structure surface through the extension of the second cylinder 3.

[0038] Furthermore, the annular airbag sheet 17 is in contact with the external structure surface through inflation and expansion.

[0039] When in use, when the mouth of the outer conical cover 8 is inside the building concrete slurry, the second cylinder 3 is in a contracted state and the piston 7 connected thereto moves along the suction and discharge pipe 6 from bottom to top, so that the building concrete slurry enters the space formed between the outer conical cover 8 and the inner conical cover 9 through the suction and discharge channel;

[0040] When the second cylinder 3 is in an orderly intermittent extension state, the piston 7 moves along the suction and discharge pipe 6 from top to bottom, so that the sucked building concrete slurry is squeezed and discharged to the front of the rectangular concave surface 910;

[0042] When it is necessary to push and add the building concrete slurry in front of the rectangular concave surface 910 to the internal connection of the pipeline, the third cylinder 12 is in an extended state and pushes the connected push-pull material block 13 outward, so that the outwardly moving push-pull material block 13 pushes and adds the building concrete slurry in front to the internal connection of the pipeline. After the pushing and adding is completed, all structures are reset, and then the overall structure is rotated to adjust the horizontal position, so as to push and add building concrete slurry to other parts of the internal connection of the same pipeline wall;
