Drilling method is an important support in large diameter steel wall shaft construction for small state-run enterprise, township enterprise, collective enterprise, collective enterprise, private enterprise and individual enterprise with its advantages of short construction period, low cost and high safety. But to now, the study on the construction technology of drilling method for large diameter steel wall of shaft obviously lags behind the market development requirement, the paper introduces the construction technology in wellhead positioning tube burying, wellhead locking, slurry circulation system, equipment installation, hole drilling, hole reaming, well washing, shaft casing, sealing by grouting (cementing), slurry discharging and cementing examination.
