Semi reversed Construction Method in Full mechanized Excavation of Tianjin Hualian Commercial Building

介绍全机械挖土半逆施工技术利用地下连续墙、钢管柱、零层板构成完整的支撑体系，零层板浇筑后预留孔洞，挖土机采用接力运土方式实现全机械化率９５％以上。

The semi reversed construction method for full mechanized excavating introduced in this article relies on the underground continuous wall,steel tube column and the zero floor board to form the integral bracing system.Holes are preserved in the zero layer board.A relay style transport method is used by excavators and mechanization ratio is above 95 percent.
