With the constant change of scale and application form of water resources and Hydropower projects, circular tunnel design has been widely used in construction. The main channel of Jiayan Water Control Project is a circular tunnel. The circular tunnel can save excavation and concrete lining and make full use of tunnel space. However, excavation and concrete lining construction are relatively difficult, especially the construction quality of concrete lining using needle beam formwork trolley needs strict process control. In order to improve the quality of concrete lining and speed up the construction of concrete, the selection and installation of needle beam trolley are strictly controlled during the implementation process. The concrete lining is constructed by pipeline. After the implementation of the project site, the quality and construction progress control of concrete lining has achieved good results.
