CONSTRUCTION METHOD FOR PREVENTING A LEAK THROUGH CRACK OF CONCRETE STRUCTURE

摘要

The present invention relates to a leak crack repair method for repairing cracks in concrete spheres by injecting a repair material, and more particularly, by repairing a filling part filled with repair material in a T-shape to expand the repair area that meets an irregular crack surface to improve repair performance. In addition, the present invention relates to a leak crack repair method that improves field applicability and repair performance by adopting rubberized asphalt waterproofing material containing bentonite as a repair material.;Leakage crack repair method of the concrete sphere of the present invention is to repair and strengthen the concrete sphere in which the crack occurred, (a) a vertical drilling step to form a vertical inlet by drilling along the crack vertically from one surface of the concrete sphere; (b) a horizontal perforation step of forming a horizontal space by perforating horizontally from the vertical inlet in the state of securing the other surface coating thickness of the concrete sphere; And (c) an injection step of filling the repair material through the vertical inlet to fill the repair material with the vertical inlet and the horizontal space.;Mat base, water leakage, crack repair, water jet, repair material
