预压试验技术在向家坝灌区渡槽工程施工中的应用

Application of Pre-pressure Test Technology in Construction of Aqueduct Project in Xiangjiaba Irrigation Area

“向家坝灌区北总干渠一期一步工程”是现阶段四川省在建最大水利工程,如何解决渡槽槽体混凝土浇筑施工中存在的技术风险,安全风险,质量难以保证等问题,是建设者们面临的最大挑战。为确保渡槽槽体各项指标符合设计要求,槽体浇筑混凝土前支撑系统预压试验尤为重要,对预压试验数据进行研究分析,能保证渡槽混凝土浇筑施工质量安全,杜绝事故发生。

North Main Channel Phase IProject of Xiangjiaba Irrigation Area is the largest hydraulic project under construction in Sichuan Province at this stage.The biggest challenge faced by constructors is how to solve the problems of technical risk,safety risk and quality difficulty in concrete placing of aqueduct body.In order to ensure that all indexes of the aqueduct body meet the design requirements,the preloading test of the front support system of concrete placing in the tank body is particularly important.The study and analysis of the preloading test data can ensure the quality and safety of concrete placing for the aqueduct and prevent accidents.
