施工中トンネルの発電方法および施工中トンネルの発電システム

摘要

PROBLEM TO BE SOLVED: To provide a power generation method for a tunnel under construction and a power generation system for the same capable of saving power consumption of equipment in the tunnel under construction.

SOLUTION: Turbid water discharged in association with construction of a tunnel 12 is treated with a turbid water treatment facility 18 and stored in a discharge tank 1806 as treatment water. The treatment water in the discharge tank 1806 is transferred to a pipe conduit 24 with a second submerged pump 25. The treatment water transferred to the pipe conduit 24 flows through the pipe conduit 24 toward a discharge port 2404 by pressure of the second submerged pump 25 as well as a water head difference of the pipe conduit 24. A waterwheel 2602 of a power generation unit 26 is rotationally driven by the treatment water sprayed through the discharge port 2404 (a spray nozzle 2404A) to enable a generator 2606 to generate power. The generated power is supplied to respective lighting equipment 32 from a distribution board 28 through a cable 38 and thereby activating the lighting equipment 32 to illuminate the turbid water treatment facility 18.
