摘要
深中通道因沉管隧道具有“超宽、深埋、变宽”等特点,首次大规模应用钢壳高流动性混凝土结构,采用工厂法预制。依托深中通道,通过大量试验确定了混凝土配合比和性能指标,研发的智能浇筑设备实现了各项浇筑参数的智能控制。基于足尺模型试验的成果,从混凝土过程控制、浇筑顺序设置、混凝土布料、设备布置和浇筑过程等方面形成了一套自密实混凝土浇筑成套施工技术。
Because of the characteristics of immersed tube tunnel,such as super wide,deep buried and widened,ShenzhenZhongshan Link is the first large-scale application of steel shell and high fluidity concrete structure,which is prefabricated by factory method.Relying on Shenzhen-Zhongshan Link,the concrete mix proportion and performance indexes are determined through a large number of tests,and developed intelligent pouring equipment has realized the intelligent control of various pouring parameters.Based on the results of full scale model experiment,a complete set of construction technology for self-compacting concrete pouring is formed from the aspects of concrete process control,pouring sequence setting,concrete materials,equipment layout and pouring process and so on.
