Difference changes the influence of the various internal and external factors such as big, and concrete structure inevitably has some cracks.These cracks are also
Cause concrete structure bearing capacity, durability, especially the main cause of water proofing property reduction.
Mainly there are resin infusion, surface-closed, grouting, caulked, stickup, steel currently for the restorative procedure of distress in concrete
Muscle reinforcement, self-closing legal, sealant and coating surface impregnating method, wherein resin infusion, grouting and caulked method are mainly led to
Cross and realize the reparation in crack to the material such as perfusion resin or concrete in distress in concrete, or the suitable material of caulked；Surface is sealed
Close, paste, sealant and coating surface dipping method mainly use the materials such as band, sealant, coating to concrete structure
Surface is sealed, and so as to prevent steam, chemical substance and carbon dioxide etc. from invading crack, reaches repairing purpose；Reinforcing bar is strengthened
The continuation for mainly preventing crack by mechanical means expands, and realizes repairing；Self-closing rule is there is moisture and do not having
Under conditions of action of pulling stress, there is series of chemical by moisture and carbon dioxide in concrete itself and air etc.
After close up crack, and then reach the purpose of crack reparation.Although above method can realize coagulation soil cracking to a certain extent
The reparation of seam, but these methods are mainly for the reparation of exposed concrete structural surface, for having carried out waterproof construction, being incubated and apply
The crack of the concrete structure of work or facing is repaired and stills need again to be repaired the constructing structure destruction of concrete structural surface,
Not only construct cumbersome difficulty, waste time and energy, the outward appearance of building, the globality of building structure and security are also subject to serious shadow
Ring.
The content of the invention
The utility model repairs difficult problem for the purpose of solving the above problems mainly for concrete structure crack,
A kind of polymer compound film that protection and repair are played to concrete structure is designed and developed out, the composite membrane is embedded in building in advance
Concrete structural surface, can not only repair the space and crack of concrete structural surface, prevent steam, chemical substance and titanium dioxide
Carbon etc. further invades crack, also self-regeneration can be carried out to the self-protection layer breakage caused by construction wrong, while mixed
Xtah Crude Clay structure surface constitutes one layer of waterproof, impervious protecting film, and alternative traditional building waterproof layer improves concrete structure
Water proofing property and the long-term water permeability resistance of building structure.
To achieve the above object, the utility model uses following technical proposals：A kind of concrete with self-repair function
Structural shielding and reparation polymer compound film, the composite membrane are mutually composited by repair layer with main overcoat.
The repair layer is made up of the high water-absorption fiber non-woven fabrics of water-swellable.

Material is made.
Further, the high water-absorption fiber non-woven fabrics of the water-swellable impregnates high-hydroscopicity tree by general fibre non-woven fabrics
Fat is made, or is made up with high water-absorption fiber blending of general fibre.
The general fibre is cotton fiber, viscose rayon, polyethylene fibre, polyster fibre, polypropylene fiber or continuous synthetic fibre fiber.
Further the main overcoat passes through film technique or heat pressing process or adhesive bonding mode and repair layer
It is mutually compound.
A kind of concrete structure protection and reparation polymer compound film with self-repair function, its application process is such as
Under：
1. when being applied to the protection of precast concrete, tunnel, side and superstructure existing concrete structure：Anti-
Before the construction such as water, insulation, facing, by the polymer compound film repair layer towards concrete, make repair layer and mix
Xtah Crude Clay structure surface is in contact, by being mechanically fixed or polymer compound film is fixed on concrete structure by adhesive bonding mode
Surface, then carries out heat preservation construction or Decorative Construction in main protection layer surface.
2. when being applied to inferior rear pouring concrete structural shielding：By the polymer compound film overcoat towards basis
Layer, repair layer is laid in basic layer surface or by being mechanically fixed or adhesive bonding mode is fixed towards rear pouring concrete layer
In basic layer surface, then repairing clad surface carries out rear pouring concrete construction.
3. when being applied to the precast concrete preparation with safeguard function：The polymer compound film is placed in mould
Inside, overcoat is laid in mould inner surface or by being mechanically fixed or adhesive bonding mode is fixed towards mould inner surface
In mould inner surface, concrete is then injected in the mould for fixed polymer compound film, concrete is combined with macromolecule
Film repair layer is contacted, and the precast concrete with safeguard function is formed conserve on schedule after.
The beneficial effects of the utility model and feature：
Compared with existing repair materials, its feature is the utility model：When in work progress or construction the later stage building
During thing use, when there is crack or polymer compound film itself breakage and moisture-inhibiting or infiltration because of concrete structure, macromolecule
Water swelling is formed gel by the repair layer of composite membrane, and the pressure blockage crack produced during by water swelling, and then to mixed
Solidifying soil cracking seam or itself breakage are filled reparation.Additionally, the pressure that repair layer is produced when expanding will further prevent coagulation
The occurrence of moisture-inhibiting, infiltration of soil structure.The space of concrete structural surface can be not only repaired after its repair layer water-swellable
And crack, prevent steam, chemical substance and carbon dioxide etc. from further invading crack, moreover it is possible to the protection to causing by construction wrong
Layer breakage carries out self-regeneration, and composite membrane plays more preferable overcoat effect after making reparation.Additionally, overcoat of the present utility model
One layer of waterproof, impervious protecting film, alternative traditional building waterproof layer can be constituted in concrete structural surface.The utility model
Application be conducive to the integral protection of building concrete structure, can further improve water proofing property and the building structure of concrete structure
Long-term water permeability resistance.
