溪洛渡水电站出线竖井整体式滑模混凝土施工技术

The Integral Sliding Form Concrete Construction Technology for Outgoing Shaft of XIluodu Hydropower Station

本出线竖井类属于大直径开挖断面,其衬砌结构体型复杂,大井内被中隔墙分隔为7个小井,通过整体式滑模施工技术的设计与运用,实现了多个联体仓位同步滑升,确保了结构的整体性,具有施工速度快、机械化运用程度高、省掉支模和搭设脚手架施工工序等优势,大幅度降低了施工难度,显著提高了施工工效。

This outgoing shaft has the excavation section with large diameter and the lining structure with complex shape, the big shaft was separated by mid-partition into seven small shafts, and the design and application of integral sliding form construction technology realize the synchronously sliding of multiple conjoined storage bin, guarantee the structural integrity, gave the superiorities of quick high speed of construction, high degree of mechanization, and eliminating the formwork and scaffold erection process, etc., greatly reduce the construction difficulty, and obviously improve the construction efficiency.
