余吾煤业南风井立井井筒冻结外壁快速施工技术

Vertical Shaft Freezing and Outside Wall Fast Construction Technology in SouthAirshaft of Yuwu Coal Industry

井筒掘砌、冻结外壁采用大吊桶、中心回转式抓岩机、自动配料系统、单缝式液压脱模整体金属(带刃脚)下行模板、强制式混凝土搅拌机等先进机械设备进行快速施工。采用中孔、光面、弱震、弱冲、抗杂导爆管等爆破先进的施工技术,组织优质快速施工,取得了良好的成绩。

Fast construction for digging shaft and freezing wall was implemented by using advanced equipment which contained skiphoist,center rotary grasp rock machine,automatic batching system,single-slotted hydraulic stripping overall metal template and forced concrete mixer.Advanced blasting technologies with hole,smooth,weak shock,weak rushed,anti-noise nonel were adopted.Rapid construction with high-quality organization achieved good results.
