To provide a low-pressure injection device capable of using both an injection hole for injecting an injection material and an anchor hole for supporting a reinforcing material such as a steel plate, and a method for repairing a reinforced concrete structure using the same.SOLUTION: A low-pressure injection device 1 that injects injection material into a reinforced concrete structure at low pressure without using power includes an injection portion 3 that accommodates and injects the injection material, and an anchor portion 2 that is fixed to a hole drilled in the reinforced concrete structure. An injection hole for injecting the injection material is bored in the anchor portion 2, and the injection portion 3 and the injection hole are provided in communication with each other.SELECTED DRAWING: Figure 1 【課題】注入材を注入するための注入孔と鋼板などの補強材を支持するためのアンカー孔とを兼用することができる低圧注入器具及びそれを用いた鉄筋コンクリート構造物の補修方法を提供する。【解決手段】鉄筋コンクリート構造物に注入する注入材を動力を用いずに低圧で注入する低圧注入器具１において、前記注入材を収容して注入する注入部３と、鉄筋コンクリート構造物に削孔した孔に固定するアンカー部２と、を備え、前記アンカー部２に、前記注入材注入用の注入孔を穿設し、注入部３と前記注入孔とを連通して設ける。【選択図】図１
