[0031] Further, as Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, on the outer side of the edge of the precast pipe square pile 3, a semi-open installation groove 17 adapted to the plugging block plate 4 is provided. A sealing gasket 18 is arranged in the semi-open installation groove 17. A rotating groove 19 adapted to the rotating shaft of the rotating handle wheel 11 is provided on the outer side of the plugging block plate 4. An internal hexagonal groove 20 is provided on the nut of the butterfly fixing bolt 12. A spacer 21 is arranged between the first group of rack bars 8 and the second group of rack bars 9 for the gear 7. The semi-open installation groove 17 is convenient for the plugging block plate 4 to be clamped and installed on the side of the precast pipe square pile 3, so that the plugging block plate 4 is flush with the side of the precast pipe square pile 3 after installation, thus not affecting the plugging block plate 4. The sealing gasket 18 is convenient for increasing the sealing performance of the contact surface between the plugging block plate 4 and the precast pipe square pile 3. The rotating groove 19 ensures that the rotating handle wheel 11 and the plugging block plate 4 are rotationally connected. The internal hexagonal groove 20 is convenient for tightening the butterfly fixing bolt 12 again by an internal hexagonal wrench. The spacer 21 is convenient for limiting and supporting the first group of rack bars 8 and the second group of rack bars 8 which are not in the same plane and for spacing.

[0032] As Figures 1 - 5 shown, the principle of the air defense project wall hole plugging structure provided in this embodiment is as follows: When the device is used, the slot holes 2 should be reserved in advance before pouring the air defense wall 1, and the precast pipe square piles 3 should be fixedly poured and installed in the reserved slot holes 2 when pouring the air defense wall 1. Then, after the precast pipe square piles 3 are installed in the reserved slot holes 2 where ventilation openings or pipes need to be installed, the ventilation openings or pipes are directly installed on the side of the precast pipe square piles 3, and the gaps of the installed pipes are sealed;

[0033] When facing some temporarily idle reserved slots 2, temporary plugging is required. At this time, the plugging block plate 4 can be clamped in the semi-open installation groove 17. However, it is necessary to ensure that a gasket 18 is placed between the plugging block plate 4 and the semi-open installation groove 17. Then, the butterfly fixing bolt 12 at the end corner of the plugging block plate 4 can be manually tightened and pre-fixed on the precast pipe pile 3 in advance. Then, an inner hexagon wrench is aligned with the inner hexagon groove 20, and the butterfly fixing bolt 12 is tightened and fixed. Subsequently, the turning handle 11 can be rotated. At this time, the turning handle 11 will drive the second rotating connection block, the gear 7, and the first rotating connection block to rotate synchronously and in the same direction in the plugging block plate. At this time, the first set of racks 8 and the second set of racks 9 meshing with the gear 7 start to extend synchronously until the first rack 801 pushes the first insertion block 803 into the first slot 101, the second rack 802 pushes the second insertion block 804 into the second slot 102, the third rack 901 pushes the third insertion block 903 into the third slot 103, and the fourth rack 902 pushes the fourth insertion block 904 into the fourth slot 104. Ensure that the plugging block plate 4 is completely inserted and fixed on the precast pipe pile 3.
