What are the steel reinforcement methods?
Nail method When the tensile strength of the main fracture section must be restored, it is appropriate to use the nail method. Especially in the case of not damage the surrounding structure is used to lock the active cracks. With a relatively thin and long metal "stitched U-shaped nail" across the cracks embedded in the well to open a good groove, with no shrink mortar or epoxy-based adhesive to fix. 4. Surface closure method This is the easiest and most common method of crack repair
Polymer immersion method 2.1 gravity infiltration method Low viscosity liquid resin can be used to seal the road surface, the bridge is not less than 0.1 mm cracks. Brush the resin onto the surface, or build a temporary embankment along the crack on a horizontal surface, causing the resin to spill over the surface of the crack. 2.2 Vacuum infiltration method is more suitable for closed multiple irregular surface cracks. First seal the surface of the crack, pumping a vacuum, so that cracks and pores in the air all excluded. And then under the atmospheric pressure with pure epoxy resin slurry into the crack surface.
Resin infusion Epoxy resin is the most common crack infusion material. It has a high mechanical strength, and can resist most of the chemical erosion encountered by concrete, resin can be poured into the 0.05 mm cracks. In addition to some special epoxy resin, when the cracks are active, there is leakage, can not dry or a large number of cracks, usually easy to use resin infusion method. OKorder Metallurgical Engineering Crack Treatment Center developed with the international leading level of engineers Automatic low pressure grouting technology is one of the best method of resin infusion method.
