After g, mixed alkaline residue, flyash are discharged into the absolute altitude of backfill, water discharging on the face is done, allowing it dewater naturally dries, when digging machine can start on the ground by the time, ditch with digging machine, the original place is dark more than 20 centimetres during the depth ratio backfill of ditch, and the water pump draining is installed in the ditch, and the distance between ditch and the ditch is 8 meters～15 meters.
After h, backfill soil were dried naturally, the face of the natural soil of ditch bottom being translated into after the backfill with digging machine came up, and the mixture of alkaline residue, flyash is filled out to be put in the ditch go.
I, the natural soil that digging machine is translated into the backfill soil surface cover on the good ground of backfill, and it is real to push away concora crush with dozer.Upper layer and natural earthen backfill difference after the backfill are reduced.
If j plants greening, add a cover mountain soil again above the greening place with the needs plantation.
