Abstract

Limited by the complexity of the mechanism of the pumping pipeline and the construction environment in the pumping pipeline during the process of pumping out the shore, it is impossible to allow precise measuring instruments to measure internally. In the past, domestic and foreign scholars only used key equipment such as mud pumps. Work characteristics are studied and related mechanism models are established. In view of this situation, the mechanism analysis of the trailing suction dredger and the calculation method of the mechanism model are carried out, combined with the existing research results and engineering experience, the water layer model and empirical formula are used to obtain this working condition. Under the mechanism model of the extraction of the cabin pipeline, the key parameters of the extraction of the cabin obtained by the mechanism model are verified by the CFD (Computational Fluid Dynamics) software. The results show that the key parameters of bank extraction and bank blowing calculated based on the mathematical model obtained from the mechanism analysis are put into the CFD software and the results obtained are generally in line with reality. It provides a way for future research on the mechanism of the pumping and bank blowing of the trailing suction dredger. Mathematical model reference.
