The invention discloses an air vent with a diversion tunnel reconstructed into arc-shaped gate control and an arrangement method. The air vent comprises a water inlet tower (1) which is arranged at the upstream of a to-be-modified diversion tunnel (2), wherein an air vent (1.1) is pre-arranged in the water inlet tower (1); an inlet gradual-changing section (3) is arranged between the water inlet tower (1) and the to-be-modified diversion tunnel (2); an ecological dewatering tunnel section (2.2) is sequentially divided into a section M and a section N, wherein the section M is a concrete reconstructed body A (4) which is formed by pouring concrete to the ecological dewatering tunnel section (2.2); and a water release channel (2.2.1) is reserved in the bottom of the concrete reconstructed body A (4). The air vent overcomes the defect that a gate and other drainage facilities are damaged by a negative pressure region behind the gate as air is taken away by outflow sluice during full-flow aerial drainage, and has
