Stick is pressed into bottom or press-in side wall, once this phenomenon occurs, percolating water phenomenon is more prone to often in practice of construction
Occur.In fact, foam rods are filled in fluid sealant, originally in order to reduce the modulus of fluid sealant, but due to its structure still
Or single track sealing, there is no the safety coefficients for fundamentally improving water-proof function.
The waterproof of some seams, especially underground engineering, the method that some uses grouting stop leakage temporarily, but practical
Shorter using effective time, after a period of time, seam is easy to that leakage problems occur again.
It is used in combination using tire base fabric with the water-proof film of coating with fluid sealant, if covering fluid sealant is with tire base fabric
Bridge technology for coating and in seam using the waterproof coating of U-shaped tire base fabric and the spill bridging technology of fluid sealant, Ke Yi great
Big raising water resistance and durability.This is a kind of solution style of seam, still, snaps into seam outer ledge, has
Appearance requirement is just not suitable for.It has no idea to put up a bridge or be impermissible for connecing for bridging technology using grid cloth film for some
Seam waterproof and using put up a bridge occur problem of appearance or have no idea operation the problems such as, it is necessary to using innovate method come
It solves.

Matter applies oil product in film material and is migrated by substrate surface to porous material 5.High intensity, high compact are employed in the utility model
The base treatment agent of degree handles the inner wall surface of seam base material.To reach the mesh for the steam buffer brake for resisting porous material
's.In general concrete, saturation aqueous vapor is adsorbed, has been exposed to the sun under the outdoor sun, but when temperature reaches 70-80 °C, buffer brake
Reach 5-6kgf/cm2.Common fluid sealant, silane coupling agent, adhesive adhesive strength are provisional can also to reach 5-6kgf//CM2.
But that is the endurance on an average value, that is, unit area, since concrete is porous, each unit spot
Bonding may not be attained by more than average value, in weak place, defect can be slowly increasing, is finally reversely pressing for a long time
Under power effect, effective cementability is lost.Therefore, the utility model uses the base treatment agent of high intensity, thoroughly closes base
Layer, makes its anti-buffer brake reach more than 5kgf/cm2.The effect that this base treatment agent reaches:A, Defect Base is repaired;B、
Closed pore;C, closed allround base;D, anti-buffer brake.And it can reach in soaking water, alternation of wetting and drying, high/low temperature
Basic requirement, finally, it is ensured that reverse water pressure cannot destroy seam base, and the possibility oil product of fluid sealant and thick matter film is difficult to lead to
