Description
Technical field
The invention belongs to ground roof waterproof maintenance engineering, and in particular to one kind reconstruction construction of waterproof layer technique.
Background technology
At present, although basement roofing and side wall are coated with waterproof layer in work progress, but still it is susceptible to seepage
Serious problems, through analysis, its reason be broadly divided into it is following some：1st, roofing element is more, and lamp socket stationary nodes penetrate waterproof layer；2、
Node is more, and waterproof layer and top board have quality problems from impervious concrete；3rd, the construction method of waterproof layer is improper, major embodiment
In place where troops were originally stationed water layer, a little intake, everywhere channeling water, be not reaching to the antiseep requirement for closing completely；4th, roofing winter is cold, summer heat
Protective layer, waterproof layer and its waterproof efficacy from impervious concrete are destroyed after causing existing Stress Release Deng micro-strain；5、
Uneven resistance to plucking, resistance to compression and the temperature difference release etc. occurs in roofing causes former design waterproof layer to receive different degrees of heavy damage；
6th, after roofing floor tile adhesive, expanded with heat and contract with cold, stress extruding causes have peeling between waterproof layer；7th, under floor tile
Water enters, rainwater play everywhere inside waterproof layer, leaks down from weakness.
The waterproof object of Chinese architecture more than 90% is concrete structure, and waterproof layer can not be carried out effectively to concrete structure
Sealing, break a bit, leak a piece of, cause whole waterproof system to fail.The reason for concrete construction anti-shipwreck, also resides in concrete
Fire resistance characteristic is more complicated, is embodied in：1）Infiltration characteristic（Concrete structure has pore, porosity to account for 25% or so）；2）Cracking
Property, crack dynamic（The factors such as the temperature difference, load-bearing, vibration, dry and wet）；3）It is dampness, out-of-flatness, unclean（Concrete basal plane is because overworking
The reasons such as phase, weather）.
Therefore, a kind of construction of waterproof layer technique of reproducing is developed to prevent the ground of appearance, roofing in the existing construction building of solution
Water maintenance problem is very necessary.
The content of the invention
It is an object of the invention to provide one kind reconstruction construction of waterproof layer technique, existing construction is simply and quickly solved
Ground, the roof waterproof maintenance problem occurred in building.
To achieve the above object, the present invention uses following technical scheme：
Reconstruction construction of waterproof layer technique, comprises the following steps：
1）Injected hole is worn in construction surface, and Grouting Pipe is buried in hole；
2）By Grouting Pipe first to back side filler is injected in hole, waterproof material is reinjected；
3）After construction terminates, ascending pipe, plugging construction hole are removed.
Step 1）In, perforate to place where troops were originally stationed water depth, a diameter of 15~18mm of Grouting Pipe.
Step 2）In, the back side filler is waterborne polyurethane foaming grouting material；The waterproof material is uncured rubber
Glue asphalt waterproofing paint.
Step 3）In, using RE-PH mortars and non-woven fabrics plugging construction hole.
Each slip casting pitch of holes is worn in construction surface for 0.5~1.5m.
Step 2）In, during injection back side filler and/or waterproof material, until occur adverse current in surrounding injected hole can stop
Only.Step 2）In, the pressure for injecting waterproof material is 20~30bar, and speed is 25~75L/min.
Base plate underground can be expelled to by equipment using construction technology of the invention, one layer of waterproof layer is reproduced, and repair automatically
Multiple underplate concrete crack blocks water entry, seals channeling water passage；Channeling water layer becomes sealant, and existing so as to reach sealing purpose
There is technology to compare, beneficial effects of the present invention are：
1）Small perforation, reproduces Durable Water Repellant；
2）Water penetration is solved, destruction is no longer expanded from this；
3）Channeling water layer becomes sealant；
4）Unknown water entry is repaired automatically；
5）Distress in concrete leakage point automatic-sealed.
Specific embodiment
With specific embodiment, the present invention will be further described below.
Waterborne polyurethane foaming grouting material used is to be reacted by Hydrophilicrto polyether polyalcohol and isocyanates in embodiment 1-3
End contain a kind of polymeric grouting materialses of isocyanato.The material chemically reacts after meeting water,
Elasticity glue induration is formed, is a kind of new waterproof leak stopping high pressure pouring material so as to reach good sealing purpose；
Uncured rubber asphalt waterproof coating used is the flexible waterproof coating of a kind of high polymer and pitch mixing, can directly be smeared
Used in basic unit, treat that moisture evaporation forms one layer of fine and close waterproof membrane of sticky body of paste.
Above two material is provided without leakage waterproof Science and Technology Co., Ltd. all over the world by Henan.
