Design And Application Analyses Of Assembled Diversion Pile Dam

At present,the work of the river course of the lower reaches of the Yellow River has been basically completed.In recent years,according to the situation of the existing projects,the river regulation works planned by the Yellow River Conservancy Commission are mostly extended and delayed Continued construction.In fact,many of the continued construction of the layout of the location has gone beyond the original water treatment program layout range.In order to reduce the adverse effect of this part of the dam on the flood and the water and sediment exchange of the beach.Therefore,the study at the same time to meet their own stability,does not affect the beach water and sediment exchange and drainage,but also control the river,and the removal of simple,easy to move,economically reasonable structure of the structure of the dam-Assembled diversion pile the dam.Therefore,under the guidance of the tutor,the author carried out an analysis and research on the design and application of the downstream construction-type diversion pile dam of the Yellow River.The main work and results are as follows:(1)The structural form of grouted diversion pile dam is determined from the performance comparison and analysis of different types of dam structures.(2)Combined with the practical application of dike condition,to determine the pile packaged diversion dam crest elevation plane layout scheme,design flow and,using the formula of scour depth are commonly used to scour depth are calculated and determined,and the dam body pipe pile using the force analysis and calculation,according to the calculation results and the relevant specification to determine the structure of the dike design,and the reinforcement for the pipe pile is calculated.(3)According to the verification results of different scour depth and the comparative analysis of the observation results of the test project,the calculation formulas for the reasonable pile length and scour depth of pile-dam pile-dam pipe piles of packaged diversion piles are recommended.
