A煤矿采用一对主副立井方式开拓,该主副井井筒均在同一工业广场内,某施工单位承担了该主井井筒施工项目。主井井筒净直径5m,深度650m,表土段采用冻结法施工;某项目经理计划采用JKZ-2.8专用凿井提升机配一3m3吊桶提升和1台JK-2.5提升机配2m3吊桶提升,以加大提升能力,并配2台HZ-6型中心回转抓岩机出渣;该井筒在基岩段共穿过两个含水层,厚度分别为15m和30m,相隔30m,两个含水层最大涌水量均为40m3/h。在施工到第2层含水层发现井筒上段漏水量较大,脱模后蜂窝麻面较为严重。该井筒竣工后井筒涌水量达15m3/h,其中冻结表土段井壁有较为明显的漏水现象,遂决定对表土段进行壁后注浆堵水。
该项目的施工方案有何不妥?为什么?

Voice{{/B}} Often speakers at a meeting experience dry mouths and ask for a glass of water. You can solve the problem by activating the saliva in your mouth.
