净径5.5m立井凿井设备的配套与优化布置

摘要

较大直径的井筒,施工设备选型和平面布置相对比较容易;而对于较小直径井筒,由于受平面尺寸限制,施工设备选型和平面布置有一定难度。笔者结合净径5.5 m的立井井筒施工实际,提出了平面设备布置优化方案,取得较好效果。%Compared to large-diameter shaft,the construction equipment selection and the layout for small-diameter shaft is more difficult due to its restrictions of plane dimension.Combining with the construction case of 5.5m-net-diameter vertical shaft,the author
