AB  - The prediction of sediment deposition in the foundation trench is mainly for the construction of deep and medium channels. Based on the numerical simulation prediction system, the prediction value of sediment deposition thickness in the foundation trench is given during the construction of E1-E9, a total of 9 pipe joints. The prediction provides an important support for the decision-making and construction organization of the pipe sinking construction. From the actual results, it can be seen that the prediction value can accurately determine whether the design requirements are met, providing an accurate basis for construction. The data time range is from June 2020 to April 2021, the prediction data of sediment deposition during the construction of E1-E9 pipe joint sedimentation. Each prediction is based on the construction organization arrangement, predicting the daily and cumulative sediment deposition thickness between the beginning of gravel leveling and the completion of pipe sinking construction.
