Description
Technical field
The invention belongs to construction material preparation technical fields, and in particular to a kind of tunnel water proofing layer material and its preparation
Method.
Background technique
Currently, more and more railways are repaired to remote mountains with the development of China railways, need to dig tunnel, it is some aqueous
The problem of mountain area abundant, the tunnel of cutting are frequently run onto leak, infiltration.At this stage, domestic railway tunnel waterproof/drainage structure is more
Number adds the form of splash guard using geotextiles, and no matter this structure type theoretically or in practical projects all exposes perhaps
More drawbacks, such as with just prop up the not high, technique of closely connected degree require it is high, disappear it is light it is big, waterproof weak spot is more, in its external spray waterproof membrane
It is a kind of improved procedure of optimization, waterproofing membrane material has neoprene, pitch, propylene hydrochlorate, polyurethane, polyureas etc..
Since mid-term the 1990s, spray-on tunnel film waterproof technique has obtained correlative study in China.1995
Year, the tunnel spray film waterproof technique based on propylene phosphate-gallate series have had research and development successfully to report, subsequent spray film waterproof filmogen,
The development of corollary equipment, construction technology, has reached its maturity, and it is two-component, double spray heads height that propylene hydrochlorate, which sprays film waterproof technique feature,
Airless spraying film forming is pressed, in the horizontal direction, spray film layer is divided into outlier and embeding layer, can regard impermeable stratum as；For
Non-woven geotextile layer, due to spraying the insertion of film layer, the part for losing drainability is colmatation zone, is included into spray film embeding layer,
Can regard impermeable stratum as, the unaffected part of drainage performance is intact layer, by equally distributed circular hole hole with it is waterproof
Fiber skeleton formed.
Propylene hydrochlorate spraying film waterproof itself flexibility height, good integrity, speed of application are fast, however showing by multiple engineerings
Field test discovery, spray film waterproof technique is applied to railway tunnel waterproof, and there is also some critical issues not yet to solve, many technologies
There is no specific index parameters, so that site operation is more random, there are certain randomnesss for spray film quality, spray the durable of film
Property is poor, needs to be formulated it further improvement.
