Embodiment
Embodiment 1：As shown in Figure 1, the present embodiment is a kind of concrete joint resistant abrasion for being arranged at movement joint sealing
Joint seal leakage preventing structure, at seam sealing cutting have along seam arrangement a, regular 2cm wide 4cm depths slot 1, in slot 1 according to
It is secondary that compressible hollow rubber sealing strip 2 and deformation joint resistant abrasion protective layer 3 are set.
Compressible hollow rubber sealing strip 2, can using the barbed distracted hollow rubber sealing strip of 2.5cm wide 2cm thickness in this example
2 width of compression hollow rubber sealing strip is more than 1 width of slot, and extruding is placed in 1 bottom of slot, becomes seam seepage control main body.It can press
Compressible hollow rubber of 2 both sides of the contracting hollow rubber sealing strip paste in 1 both sides cell wall of slot, operational process in slot 1 is close
Strip of paper used for sealing 2 is suitable for two-way pulsation hydraulic pressure antiseepage in stable compression antiseepage state, hollow balloon all the time.
To ensure the being sealing adhesive property of compressible hollow rubber sealing strip 2 and 1 both sides cell wall concrete of slot, this example is being stitched
Twice HK-G-4 environment-friendly epoxy resin primers are painted with 1 both sides cell wall concrete of groove.
In the slot 1, compressible hollow rubber sealing strip 2 to 1 notch section of slot embed the sealing of raising strong elasticity HK polyureas
Glue or HK elastic epoxies mortar form deformation joint resistant abrasion protective layer 3, and section is dumbbell shape, increase and 1 concrete binding of slot
Area, realizes and plays effective anti-aging, resistant abrasion protective effect to compressible 2 seepage prevention system of hollow rubber sealing strip.
High-strength elastic HK polyureas fluid sealants, are divided to two kinds of the type of pouring and thixotropic, with Concrete Bond Strength>3MPa, tension
