The Research of Navigation Flow Conditions and Improvement Measures on Entrance Area and Connecting Reach of Dahua Lock in Hongshui River
The ship facilities didn’t be constructed in step with the construction of Dahua Terminal in Hongshui River of Guangxi province, while the argumentation didn’t be carried out when navigation lock was built out. In the condition above, when the navigation lock was completed, the navigation flow conditions in the entrance area of downstream and the linkage section was bad, so ships were difficult to enter the approach channel. The research of navigation flow conditions and nay navigation mechanism in the entrance area of downstream and the linkage section in current condition was implemented through physical model combining ship model. The method of using traditional navigation wall and navigation pier to improve flow conditions didn’t be adopted in renovation research. The new renovation idea of changing inflow conditions was used innovatively and bad flow pattern problem was solved by using deep pools terrain in the entrance area of downstream. After the implementation of the engineering, nay navigation problem was solved effectively and ships could pass the terminal successfully. This engineering provides a new way to solve similar terminal navigation problem.
