Description
Technical field
The present invention relates to a kind of detection methods of the leakage-proof performance of waterproof roll.
Background technique
It is well known that China's leakage of building rate is high, one of problem is exactly to exist to alter between waterproof layer and structure sheaf
Water layer.Once waterproof roll has a point to destroy, water can be leaked by breakdown point to base, if the waterproof roll
There is preferable anti-channeling aqueous, that, which need to be repaired, can be solved leakage problems at breakdown point；And if waterproof roll and base bond
Bad, then water can spread infiltration by breakdown point between coiled material and base, cause the infiltration of large area, needed at this time to entire
It is repaired or is re-started waterproof construction just and can solve leakage in face.It is only improved water-proof coiled material product and construction quality, makes to prevent
Water layer and structure sheaf tight bond eliminate channeling water channel, could improve the reliability of waterproof system.
Therefore, waterproof roll is widely used in roof, construction wall and underground engineering as a kind of flexible building material product,
It is the first barrier of entire engineering waterproofing, entire engineering is played a crucial role.Therefore the anti-channeling of waterproof roll is aqueous
It can be an important indicator of the product.
However, overlaying class waterproof roll is the unique prefabricated waterproof roll being bonded on casting concrete.Overlay waterproof
The development of coiled material solves in the waterproofing protection construction of underground engineering structure bottom plate, the bonding of structure and waterproof roll and
The problems such as engineering site laying water-proof coiled material and integrated cast structure concrete.The maximum attraction of class waterproof roll is overlay to be and structure
Concrete, which is realized, completely to be glued, and is formed skin-type waterproof, is effectively prevented channeling water phenomenon, improve the reliability of waterproofing work.Therefore, in advance
The leakage-proof performance for spreading class waterproof roll is the Key Performance Indicator of such material.
Currently, the detection method for overlaying class waterproof roll leakage-proof performance is " pre- according to product standard GB/T 23457-2009
Paving/wet-laying waterproof roll " it requires to carry out, detailed process are as follows: through-hole is offered on coiled material test specimen, concrete is cast in coiled material examination
On the bonding plane of part, impervious test piece is then packed into concrete impervious instrument, is used among impervious test piece and concrete impervious instrument mold
Paraffin is sealed, and is forced into concrete water-permeating or is reached defined test pressure, test result is observed by throwing off coiled material
Whether there is or not the exudations of bright water on waterproof roll bonding plane.
However, being fully sealed between impervious test piece and impervious mold, at concrete sample and coiled material test specimen adhesive surface each point
Suffered pressure be all from Anti-leakage instrument to unified pressure value, nothing between waterproof roll through hole and the other positions of adhesive surface
Method generates pressure difference and is all difficult channeling water phenomenon occur regardless of the bonding of waterproof roll and concrete block.Therefore the mark is used
Quasi- method can not detect the leakage-proof performance of waterproof roll.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a kind of improved waterproof roll
The detection method of leakage-proof performance, also solves that sample preparation is cumbersome, test specimen under the premise of generating pressure difference during guarantee test
