The Yan Zhou power station bridge was built on the proposed structure site of the Yan Zhou hub project, which included construction of a new ship lock, power station, and spillway gate. Due to the progress of the engineering construction, the bridge was dismantled. The Yan Zhou power station bridge is a hyperbolic arch bridge with a total length of 180.0 m and a width of 8 m. It is located in the Pengshan tourist scenic area, surrounded by many famous historical sites and enterprise factories. The environment was complex, and the nearest distance from the bridge to the existing power station dam was 8 m. The reinforced concrete box girder bridge of the power station dam was adjacent and shared a bridge pier with it. Due to the working conditions on-site, blasting demolition was adopted. In order to ensure the reliable collapse and complete disassembly of the entire bridge, as well as the separation of steel bars and concrete, the components such as arch ribs, arch columns, and connecting beams were pulverized through throwing explosive devices, with a powder factor of 1.2~1.5 kg/m. Reinforced loose blasting was used to destroy the bridge piers, and the maximum explosive charge for a single pier was 480 kg. According to the principle of heavy left and light right, the entire bridge was collapsed toward the right bank direction like a domino. An inner-hole delay and out-hole relay initiation network was used. The MS12 detonator was used for the inner-hole delay, and the industrial electronic detonators were used in parallel out of the holes. The blasting order was from left bank to right bank, and then from pier to pier, to ensure that the bridge collapsed orderly and vertically, without causing crushing impact to the left bank bridge pier. A leaky PVC was pre-laid underwater along a 100m line near the left bank power station and water roller dam. An air compressor was used to press the air into the pipe to form an air bubble curtain, which effectively reduced the water shock wave overpressure, thereby reducing the impact of blasting vibration and water shock waves on surrounding buildings and structures.
