Therefore, in the detection of the leakage, the local position of the rigid waterproof layer 16 at one end of the groove 151 may be broken, and then all the tampons 2 may be pulled out by the first connecting string 3 through the broken position, and then the water absorption condition of the tampons 2 may be checked to determine the guiding groove 152 (having rainwater flowing therethrough) at the corresponding position, which is the first dimension determination.
Then, a second dimension judgment is performed, namely, the part of the rigid waterproof layer 16 corresponding to one end of the guide groove 152 is broken (the whole guide groove 152 corresponding to the rigid waterproof layer 16 is not required to be broken), then all the absorbent cotton balls 4 are pulled out through the broken opening by using the second connecting rope 5, and then the water absorption condition of the absorbent cotton balls 4 is checked to judge the leakage condition of the corresponding position of the guide groove 152, namely, the leakage condition is specific to the specific position on the guide groove 152, then the part of the rigid waterproof layer 16 corresponding to the specific position is accurately repaired according to the specific position, and then the damaged leakage area is repaired again by using a new rigid waterproof material, so that the method is convenient and quick.
When the damaged leakage area of the rigid waterproof layer 16 is repaired, the rubber air bag column can be pushed into the guide groove 152 through the second broken opening (at one end of the guide groove 152), and is in an uninflated state or a small air charging state, so that the rubber air bag column is softer and is easier to enter the guide groove 152, and when the rubber air bag column completely enters the guide groove 152, the rubber air bag column is filled with air, at the moment, the outer peripheral surface of the absorbent cotton ball 4 is tangent to the bottom surface of the rigid waterproof layer 16 and the groove surface of the guide groove 152 respectively, so that the absorbent cotton ball 4 is limited by friction force, and the position stability of the absorbent cotton ball 4 is ensured.
Then, the first connecting rope 3 is pushed into the groove 151 through the first opening (at one end of the groove 151), and the first connecting rope 3 is placed quickly and accurately under the guiding action of the guide ball 21.
And finally, repairing the first broken opening and the second broken opening.
Namely, the above arrangement can quickly and accurately find out the damaged and leaked part on the rigid waterproof layer 16, and the cost is low.
In embodiment 2, on the basis of embodiment 1, as shown in fig. 6, a plurality of air suction nozzles 7 are communicated with the rubber air bag column, the air suction nozzles 7 are equidistantly arranged along the length direction of the rubber air bag column, and the air suction nozzles 7 are attached to the bottom surface of the rigid waterproof layer 16.
As shown in fig. 7, the air suction nozzle 7 is internally provided with a one-way air valve 6 which only allows external fluid to enter the inner cavity of the rubber air bag column, the one-way air valve 6 is used for ensuring that air in the rubber air bag column cannot overflow through the air suction nozzle 7 when the rubber air bag column is inflated, the one-way air valve 6 can adopt a conventional one-way valve structure, in the embodiment, the one-way air valve 6 comprises two fixing rings 61 fixed on the inner wall of the air suction nozzle 7, a spring 63 and a valve plate 62 are arranged between the two fixing rings 61, one end of the spring 63 is abutted on one of the fixing rings 61, the other end of the spring 63 is arranged along the inner cavity far away from the rubber air bag column, and the valve plate 62 is abutted and blocked on the other fixing ring 61.
Therefore, when the damaged leakage position of the rigid waterproof layer 16 is found and repaired, the damaged opening (which can be properly sealed) of the rigid waterproof layer 16 for the water-absorbing cotton ball 4 and the rubber air bag column to enter is temporarily reserved, a new water-absorbing cotton ball 4 and the rubber air bag column are installed, then spray water is sprayed on the repaired position of the rigid waterproof layer 16 to perform a leakage experiment, at the moment, a negative pressure device is utilized to extract air in the rubber air bag column and realize a negative pressure state of the bottom surface of the rigid waterproof layer 16 through the air suction nozzle 7, if the condition of incomplete repair still exists at the repaired position, the negative pressure can accelerate the leakage of the spray water, so that the repair condition can be rapidly judged, and the leakage condition can be conveniently ensured to be stopped as far as possible.
Embodiment 3 is different from embodiment 2 in that, as shown in fig. 8, the second connecting rope 5 includes an air bag film column 51 and a rubber belt 52, wherein the air bag film column 51 is a columnar structure made of plastic film, the rubber belt 52 is spirally wound on the outer surface of the air bag film column 51 and fixedly connected by bonding, and the spiral gap of the rubber belt 52 is a deformation gap; the absorbent cotton ball 4 is fixed on a rubber belt 52 (not shown), the air suction nozzle 7 is arranged on the rubber belt 52, and the air suction nozzle 7 is communicated with the inside of the air bag membrane column 51 (not shown).
When the second connecting rope 5 completely enters the guide groove 152, the air bag film column 51 is in a shrinking state, then the air bag film column 51 is inflated, the rubber belt 52 is driven to stretch along the spiral axis of the air bag film column, so that the water absorbent cotton ball 4 on the rubber belt is driven to perform circumferential and axial compound displacement, and in the displacement process, the outer peripheral surface of the water absorbent cotton ball 4 is tangent to the bottom surface of the rigid waterproof layer 16 and/or the groove surface of the guide groove 152 respectively, namely, the bottom surface of the rigid waterproof layer 16 and/or the groove surface of the guide groove 152 are utilized for position calibration, so that the position accuracy of the water absorbent cotton ball 4 is ensured to be improved.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
