The present invention relates to a liquid flow spraying body with a spraying nozzle having the structure of a microtube and a method of waterproof construction for microleakage cracks using the same liquid flow spraying body which can not only conduct waterproof construction conveniently without digging earth around a leakage, as to cracks and specifically microcracks generated around a leakage but also provide a clean exterior surface after the waterproof construction. The liquid flow spraying body with a spraying nozzle having the structure of a microtube comprises: a cylinder (110) filled with a waterproof solution including foamed urethane resin or silicone being used for leakage construction, and integrated, at the end of one side, with a plate-shaped mounting pad (111) to facilitate combination with a shooting body (200); a piston (120) for preventing the waterproof solution filled into the cylinder from flowing outside; a spraying body (130) formed at the end of one side of the cylinder (110) to guide the waterproof solution to be sprayed and having, on an outer circumference surface, a spiral (131) formed to enable screw-coupling with a housing (150) for injecting a waterproof solution while having an end closed instead of being penetrated; a spraying nozzle (140) integrated with the spraying body (130) and including a spraying tube (141) having the structure of a microtube in a lengthwise direction; and a housing (150) for injecting a waterproof solution, having an elastic part (151) formed so that sealing pads (152) for preventing the injected waterproof solution from being discharged outside while arranged at the outer side of the spraying nozzle (140) can move forward and backward easily via elasticity in a certain section, and having one or more sealing pads (152) formed in front of and behind the elastic part (151). |
