Special concrete grouting grouting methods of crack repair process material manufacturer for you

grouting grouting material manufacturer grouting material manufacturers know grouting material crack repair 1, direct penetration method: apply to the construction of concrete grouting material shrinkage crack. Before is not open to traffic, once found cracks in concrete grouting material, high performance grouting material available materials such as direct infusion. 2, the nozzle penetration method; Apply to traffic road repair cracks in winter. Perfusion process for; The crack-cleaning - embedding grouting mouth closed fracture - preparation - grouting - heating enhance irrigation sewing materials. Crack-cleaning; Using compressed air special nozzle with fine lead wire hook gap of mud and debris. Buried in henan grouting material which is strong mouth closed fracture grouting; Grouting mouth set a general about 30 cm, with the 2:1 ratio of rosin and paraffin wax stick heating melt fracture, reoccupy adhesive will stick good seam, and coated with rosin and paraffin. With filling and sewing materials; According to the request of irrigation seam width and open to traffic time to choose the suitable grouting material and the mixture ratio, evenly blended to pour in a small aluminum pan. Grouting; Will be configured grouting material into the organic glass syringes or other special grouting machine, general appropriate in 30 ~ 40 min with pressure drop irrigation sewing the material by the grouting in the mouth into the slot, until the filling is going to move the tape so far above. The appropriate on the add a layer of plaster and cement or mortar spraying curing the seam an agent, the surface color. Heat enhancement; General appropriate USES infrared lamp or elongated with 60 ~ 100 w bulb lamp shade in the filling and sew on heating and temperature control in 50 ~ 60 ℃, 1 ~ 2 h, heating can be open to traffic. 3, borehole grouting method; To repair the cracks can be used for the winter. Along the fissures with a impact electric drill a row of 15 mm diameter hole groove, in order to form a strip groove; Using compressed air spray gun into slots to remove concrete grouting material debris; To the little hole groove filling clean gravel along the hole CaoGuan slurry; Decorated with latex mixing cement cover slot; With infrared heating such as 1 ~ 2 h, and promote the grouting grouting material manufacturer 13521188 after 220 to strength of polyurethane grouting material, can be open to traffic. 4, syringes injections; Since this method is suitable for short cracks small debris, clean, dry and crack width in pavement repair so about 3 mm.
