Construction Technology of Integral Steel Mold in the Deep Shaft Lining Wall
Vertical shaft is a common structure of hydraulic engineering.With the rapid development of industry,the depth and diameter of vertical shaft are becoming larger and larger.The inner lining wall is a permanent exposed structure of vertical shaft.The concrete construction mostly adopts the reverse construction method.The formwork is generally an assembled steel formwork,which has high installation standards and high installation difficulty.Each use requires one disassembly and assembly,which takes a long time.The concrete construction of the inner lining wall of the working well in the Yuedong Water Supply Project adopts an electric integral steel formwork.The lifting system is pre-set around the working well,and an adjustable support rod is set outside the steel formwork as a support system.The lifting system is used to lift and lower the steel formwork as a whole,so that the steel formwork does not need to be removed,transported,or assembled during each cycle of construction.The construction efficiency will be effectively improved.The construction period will be shortened.It will obtain good economic and social benefits.
