Abstract
Xiangjiaba Irrigation District North Main Canal Phase I Project is located in the middle and low mountain areas of southwest Sichuan and northeast Yunnan.It is a super large water conservancy project second only to"Dujiangyan Irrigation Project Irrigation District"in the history of water conservancy construction in Sichuan Province,and also an important backbone project for the strategic allocation of water resources of"rebuilding a Dujiangyan Irrigation Project Irrigation District"in Sichuan Province.It has a total length of 108.25km and passes through four cities,seven districts and counties including Zigong,Neijiang,Luzhou,and Yibin.Muqiaogou aqueduct is one of the more complex and high-risk control projects in construction technology,and its structural safety,appearance quality,and leakage are particularly critical.After the completion of the project,conduct a water test on the aqueduct to check whether the bearing capacity,stress,deformation,linearity,expansion joint anti-seepage and other indicators of the aqueduct meet the design requirements.This paper provides technical support for the smooth water filling of the first phase of the North Main Canal in Xiangjiaba Irrigation District,and also provides reference for the construction of large-span prestressed hydraulic aqueducts in subsequent water conservancy projects.关键词
