9. The fire protection sealing system for plugging a water supply and drainage pipeline after passing through a wall according to claim 1, wherein: the diameter of the wall penetrating hole (10) is larger than that of the water supply and drainage pipeline (2).
10. The construction method of a fire-proof sealing system for blocking a water supply and drainage pipeline after passing through a wall according to any one of claims 1 to 9, comprising the steps of:
step one, a wall through hole (10) is formed, and if the building wall (1) is formed by pouring reinforced concrete, the wall through hole (10) is formed in the building wall (1); if the building wall (1) is formed by combining assembled wall boards, the wall through holes (10) are preset in advance when the assembled wall boards are manufactured;
installing a waterproof sleeve (3), fixedly installing the waterproof sleeve (3) in the through-wall hole (10), and attaching the outer side wall of the waterproof sleeve (3) to the through-wall hole (10);
step three, installing the rubber sealing rings (42), sleeving the two rubber sealing rings (42) at corresponding positions of the water supply and drainage pipeline (2), wherein after sleeving, the rubber sealing rings (42) and the water supply and drainage pipeline (2) are ensured not to move relatively, and one end of each rubber sealing ring (42) does not extend out of a port of the wall penetrating hole (10);
fourthly, the water supply and drainage pipeline (2) penetrates through the wall, one end of the water supply and drainage pipeline (2) penetrates out of the wall penetrating hole (10) and then is pulled until the position where the two rubber sealing rings (42) are sleeved is remained in the wall penetrating hole (10);
fifthly, plugging the wall through hole (10), firstly filling fireproof rock wool in a gap between the water supply and drainage pipeline (2) and the waterproof sleeve (3), and then respectively installing a group of fireproof sealing structures (4) at two ends of the water supply and drainage pipeline (2) to plug two ports of the wall through hole (10), wherein the compression part (41) is in a contracted state before the fireproof sealing structures (4) are installed;
step six, the fireproof sealing structure (4) is adjusted, a screw cap of a rotating screw rod (4112) in the pressing part (41) is screwed, the pressing part (41) is in an extending state, the upper pressing piece (410) is supported in the waterproof sleeve (3), and the lower pressing piece presses the rubber sealing ring (42) to seal the water supply and drainage pipeline (2) and the wall penetrating hole (10).
