The Design Of Bei Sluice In Shenzhen Jieliu River

Due to the Dakonggang area of low-lying and a lot of river,it was influenced by the tide,now its water system is imperfect,which leads to the old city river flood disaster prone and the deterioration of the river ecological environmen,It is necessary to re-plan the water system of the new airport,will be large air port to be cut in the north of river exports to build a sluice,the sluice set tide,flood discharge,landscape water and other functions as a whole,the design flow is 246 m3/s.In this paper,the author has carried on the detailed design calculation to the north gate,taking the Bei sluice as the engineering example,and considering the overall engineering layout.The main work of this paper is as follows:(1)According to the hydrological data,geological data and sluice design specifications,the grade and flood standard of the sluice are determined,and the selection of the two schemes is carried out.The water conditions,geological conditions,structure and economic scheme of the sluice And so on,and finally determine the more economical and reasonable type of sluice and layout program.(2)On the sluice over-current capacity review and energy-saving anti-Chong facilities design calculation,the power of the pool and other energy-saving facilities were arranged.(3)The safety and stability calculation of the sluice chamber is carried out under five different working conditions for the completion condition,retaining condition,tidal condition,maintenance situation and earthquake condition.The calculation results meet the requirements of anti-sliding stability.(4)Reinforcement calculation of the sluice slab and the pier structure,and the reinforcement satisfies the structural requirements.(5)The general layout of the Hebei dike was intercepted and the general plan of the north gate,the cross section and the vertical section of the north gate were drawn.
