The acceptance and monitoring part in the construction process is described in detail by taking fig. 2 as an example:
(1) and (4) acceptance:
after the construction is finished, in order to detect whether the waterproof structure at the structural joint 4 meets the design requirements, the construction quality of the waterproof reinforcing layer 2 can be judged by adopting a temporary vacuumizing mode (at the moment, a micro vacuum sensor does not need to be installed) for the reserved passage 5 corresponding to the left passage sealing plug 7A. If waterproof enhancement layer 2 has the seepage problem, then can take and carry out local restoration to waterproof enhancement layer 2 itself, perhaps repair (reverse construction method waterproof repair handles) through the mode of the port of left passageway sealing plug 7A department injects waterproof sealing material into corresponding reservation passageway 5, the flexible waterproof sealing material who injects this moment can get into reservation passageway 5 and further inject into structure seam 4 department through the port of left passageway sealing plug 7A department, reaches the effect of further sealing up structure seam 4.

And if the data meets the design requirements, the repair is finished.
(2) Monitoring:
the long-term monitoring of the structure is achieved by means of a miniature vacuum sensor through the passage sealing plug 7 c. In the later-period building use and maintenance process, once the data at the position of the micro vacuum sensor is found to be abnormal, the closed state in the reserved passage 5 corresponding to the middle passage sealing plug 7c is damaged, and a problem may occur in a waterproof system. 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.
Construction installation and later stage monitoring of the waterproof sealing structure of the structural joint 4 can be realized through the mode.
As an optional implementation manner, step S1 further includes:
the waterproof reinforcing layer 2 is not arranged between the structural layer 3 and the upstream surface base layer 1, and the upstream surface base layer 1 is directly contacted with the structural seam 4.
The structural joint 4 may be various construction joints intentionally set due to construction requirements such as a process and a construction method, for example, a post-cast strip construction joint of the embodiment, or various deformation joints intentionally set due to consideration of factors such as temperature change, ground settlement, and a quakeproof requirement, and the solution provided by the present invention is applicable.
