REMOVING METHOD FOR CONTAMINANTS FORM TILED SURFACE OF TUNNEL CONCRETE STRUCTURE AND SURFACE PROTECTIVE CONSTRUCTION METHOD TO STRENGTHEN DURABILITY OF CONCRETE STRUCTURE USING ECO-FRIENDLY SODA-BLASTING PRE-TREATMENT EQUIPMENT

摘要

The present invention, (a) spraying an abrasive containing soda on the deteriorated surface of the concrete structure to remove the coating or foreign matter remaining in the concrete structure; (b) A section that usually applies the subject including Portland cement, alumina cement, silica sand, filler, Basalt fiber, PVA fiber, and re-emulsifying resin, and a section repair material made of a fluidizing agent to the surface of a concrete structure from which a coating film or foreign matter has been removed. Maintenance phase; (c) applying a base adjustment material comprising a modified epoxy resin, adhesion-reinforced cement, and barzal fibers to the section repair layer formed in the section repair step; (d) applying a mixture containing an organoalkoxysilane, a reactive synthetic resin, an inorganic material, and a filler to the base adjustment layer to form a neutrality; (e) applying a transparent resin mixture comprising a ceramic resin, cellulose acetate butyrate, and a phase transfer material to the middle to form a top coat, wherein the step (a) comprises water or glass beads and soda stored A tank body provided with a first inlet, a second inlet, and a discharge hole so as to react; An air injection assembly installed in the second injection port to supply air into the tank body to react with soda to generate expansion pressure; Soda, water or glass beads are inserted, and the stopper assembly is installed to be opened and closed at the first injection port to seal the tank body; An adjusting member installed in the discharge hole portion and connected to the output assembly to control whether or not the soda mixture is discharged from the tank body; An output pressure regulating valve which is operated by the regulating member and adjusts the discharge pressure of the soda mixture discharged through the discharge hole portion; And installed in the tank body, the output pressure control valve, the air injection assembly and the air hose provided as the outlet assembly is installed, the output pressure control valve, the air injection assembly and the pressure by the pressure provided through the air hose It is characterized by being made by a soda blasting surface treatment device including a control box for controlling the operation of the outlet assembly.
