Summary:The invention discloses a water injectable tunnel hydraulic blasting charging device. The water injectable tunnel hydraulic blasting charging device comprises a cylindrical PVC tube for axial placement in a blast hole, two water injecting pipes, a plurality of water injecting bags, exhaust pipes and explosives. The two water injecting pipes are arranged on the left side and the right side of the highest part of a first semicircular arc shell; and a plurality of water injecting through holes communicating with the PVC pipe are formed at intervals in each water injecting pipe and the positions attaching the PVC pipe in the length direction of the PVC pipe. The water injecting bags are arranged in the PVC pipe and are arranged at intervals in the length direction of the PVC pipe. The exhaustpipes are arranged axially on the outer wall of the first semicircular arc shell; and a plurality of exhaust through holes communicating with the water injecting bags are formed at intervals in an airpipe and the positions at
