Cast-in-situ reinforced concrete strobe for diversion tunnel

The utility model provides a cast-in-situ reinforced concrete strobe for a diversion tunnel, comprising a left pier, a right pier and a bottom plate for a water inlet; the upstream place of the reinforced concrete strobe is provided with a construction water-retaining diversion steel strobe; the reinforced concrete strobe is internally provided with at least one diversion pipe that is communicated with a diversion hole on the corresponding construction water-retaining diversion steel strobe; and a diversion hole plugging steel gate is arranged outside the diversion hole. The cast-in-situ reinforced concrete strobe has the advantages that the plugging engineering quantity is less, the construction period is short, the corresponding construction charge is far less than that of the steel strobe plugging construction, and the economical and practical purposes are achieved.
