At this time, the temporary vacuum detection (at this time, the micro vacuum sensor does not need to be installed) can be performed on the reserved passage 5 corresponding to the right passage sealing plug 7b to detect the sealing state at the structural joint 4. If this reservation passageway 5 can keep the vacuum state, then explain that waterproof system still normally works, if this reservation passageway 5 can't keep the vacuum state, explain that waterproof system suffers destruction, at this moment, can select to inject flexible waterproof sealing material through the port that right side passageway sealing plug 7b corresponds into in corresponding reservation passageway 5 and realize restoreing again to waterproof system.
If the data at the position of the miniature vacuum sensor is recovered to be normal after the repairing step, the repairing is successful; if the abnormality still remains, the flexible sealing waterproof sealing material can be injected through the port corresponding to the middle passage sealing plug 7c, so as to repair the waterproof structure.
The construction method can be applied to a building waterproof system by utilizing the existing monitoring means in combination with a specially designed waterproof structure, thereby realizing the monitoring of the building waterproof system.
