carrying out reconstruction and extension on a sewage well on the south side of a seven-machine high plant, carrying out capacity expansion reconstruction on the well, wherein the depth of the original sewage well is 2.5m, the diameter of a drainage pipeline is 500mm, the area of an overflow well of a water injection tank after capacity expansion is 4.5m multiplied by 1.5m, the depth of the well is 2.0m, and the overflow water of the water injection tank is recovered;
the method comprises the following steps of (1) tapping a cable trench into a newly-built water collecting pit, additionally arranging a submersible pump in the water collecting pit, additionally arranging a float type liquid level meter, burying a pipeline for 0.6m, leading the pipeline into a water injection tank overflow well, recovering stored water in the cable trench, and solving the potential safety hazard of long-term stored water insulation aging of the cable trench;
and water in the overflow well of the water injection tank is led to a south industrial recovery water tank of the seventh locomotive, and the recovered water is led to a unit cooling water tower through a recovery pump and is used as cooling water of the unit for recycling.
