Application of Cross River Inverted Siphon Structure in Baojiang Irrigation Area
Baojiang Irrigation District Canal System Building Upgrading Project aims to solve agricultural irrigation problems and improve the design standards of water conveyance structures in the irrigation district.There is currently no inverted siphon on the main canal.Through renovation,it is planned to convert the source crossing culvert on the main canal in Baojiang Irrigation District into a head crossing inverted siphon.Through comparison,it is selected to use lined cement mortar anti-corrosion ductile iron pipes and buried layout types.It is designed with segmented structures for the import and export section,the buried pipe section on farmland slopes,and the buried pipe section across the Zhenjiang River.The head crossing inverted siphon has a flow capacity of 5.1m3/s,which meets the requirements.
