PURPOSE: A waterproofing method by a waterproof tube of an underground structure is provided to reduce the cost required for maintenance and to improve durability and safety of a main structure body. CONSTITUTION: The waterproofing method by a waterproof tube of an underground structure comprises the steps of: placing footing concrete(1) by excavating the surface of the earth in the required depth; installing waterproof tubes(5,7,9) provided with a waterproofing inspection space(11) on the footing concrete(1); installing a main structure body(3) on the waterproof tubes(5,7,9); connecting other waterproof tubes(7,9) continuously to the waterproof tube(5) to adhere closely to an outer wall or a slab of the main structure body(3), then covering up the main structure body; checking waterproofing efficiency by injecting compressive air to the waterproofing inspection space(11) of the waterproof tubes(5,7,9); deflating the inspected waterproof tubes(5,7,9) and injecting epoxy resins; and refilling up the main structure body(3).
