三峡垂直升船机高精度混凝土施工测量技术实践

Measurement Technology of Precision Concrete Construction Practice in the Three Gorges Vertical Ship Lift

针对三峡垂直升船机高薄壁塔柱结构混凝土施工精度要求,选择合适的测量仪器设备,经过实践摸索,总结出了一套适合高精度混凝土施工的测量技术方案,重点阐述了平面及高程施工控制网的垂直传递、混凝土施工放样及模板验收等技术方案。

The requirements for structural concrete construction accuracy of thin -walled tower of the Three Gorges vertical ship lift, select a suitable measuring equipment, through practice and exploration, summed up a suitable measure- ment of precision concrete construction technology program, focusing on the plane and elevation construction of vertical transmission of the control network, construction of concrete lofting and template and acceptance of technical solutions, ltn＇ concrete form of ultra - high - rise building and precision engineering control with a certain reference.
