を防止する第３工程[Scope of Claims] 1) A method for stopping water from cracks in a concrete structure, comprising steps 1 to 3 of the following a) to c). b) The first step is to plant a large number of anchor bolts along the crack lines on the surface of the concrete structure. b) A large number of thick packing drills with the required opening area are laid across the crack lines. Place a flat plate or a lid plate with a curved center on the top surface of the thick packing rill,
The lid plate is fastened with the anchor bolt, and the thick packing drill is brought into pressure contact with the cracked concrete wall, and a water sealing agent sealing space of the required volume is formed between the cracked concrete wall, the packing drill, and the cover plate. 2nd step c) Inject a water stop agent such as urethane foaming agent or epoxin resin from the water stop agent inlet provided on the fastened lid plate, fill the water stop agent sealing space with the water stop agent, and stop water. The third step is to inject the agent into the cracks using foaming pressure or injection pressure, and the water sealing agent hardens as an adhesive, sealing the cracks and preventing water leakage and infiltration. 2) The packing drill has a square-shaped wall thickness. A method for water stopping cracks in a concrete structure according to claim 1, which is an integrally molded rubber body. 3) The packing drill consists of multiple types of thick plate rubber members having fitting grooves or fitting protrusions at predetermined positions, and grills the rubber members by fitting the fitting grooves and the fitting protrusions. A method for stopping water from cracks in a concrete structure according to claim 1, wherein the method is used by connecting and integrating the structure. 4) A method for stopping water from cracks in a concrete structure, comprising steps 1 to 3 of steps a, b, and c below. a) First step of planting a large number of anchor bolts along the crack lines on the surface of the concrete structure b) A hard grill made of metal, plastic, etc. with a packing attached to the lower end and the required opening area is placed across the crack line. A large number of hard grilles are arranged in a row, and the hard grilles are fastened with the anchor bolts and fixed in pressure contact with the cracked concrete wall surface, and a flat plate or a lid plate with a curved center is attached to the upper end of the hard grilles through a packing. A second step in which a water sealing agent sealing space of the required volume is formed between the solidified and cracked concrete wall surface, the hard grille, and the lid plate c) A urethane foaming agent,
Injecting a water-stopping agent such as epoxy resin, filling the sealing space with the water-stopping agent, and injecting the water-stopping agent into the crack using foaming pressure or injection pressure, so that the water-stopping agent adheres and hardens. The third step is to close the cracks and prevent water leakage and intrusion from them.
