The Tianjin Trunk Line Project is a crucial component of the initial phase of the middle route of the South-to-North Water Diversion Project,which serves as a significant strategic initiative aimed at addressing water resource scarcity in Tianjin and ensuring sustainable development of the national economy.The main project of the Tianjin Trunk Line consists of a cast-in-place reinforced concrete box culverts,which adopts a water transmission scheme that utilizes the entire box culvert without any pressure connection or interruptions.In order to ensure the safety of the Tianjin Trunk Line operation,a box culvert test model is used and field production tests are conducted to analyze and investigate the internal treatment of water sealing materials and technologies for deformation joints leakage in box culverts.Two kinds of internal treatment methods for box culvert deformation joints,which are characterized by simple construction,strong adaptability and excellent water sealing effect hoping to provide some references for the internal treatment of deformation joint leakage in similar projects.
