【摘要】：由于大空港地区现状地势较低洼,河流水系发达且均受潮水影响,现水利工程设施不完善,导致旧城区洪涝灾害频发,河流生态环境恶化,现需要将大空港新区的水系进行重新规划,将大空港拟在截留河北出口修建一节制闸,该水闸集挡潮、排洪、景观蓄水等功能为一体,设计流量为246 m3/s。本文以截留河北闸为工程实例,在综合考虑整体工程布局,对北闸进行了详细的设计计算,本文的主要工作是为:(1)根据水文资料、地质资料和水闸设计规范,确定了水闸的等级和洪水标准,对水闸进行了两种不同方案的选比,综合考虑了水流条件、地质条件、水闸结构功能和经济方案等,最终确定了比较经济合理的水闸类型和布置方案。(2)对水闸进行过流能力复核和消能防冲设施设计计算,对消力池等消能设施进行了布置。(3)对于完建情况、挡水情况、挡潮情况、检修情况和地震情况五种不同的工况下进行了闸室安全稳定计算,计算结果满足抗滑稳定要求。(4)对水闸底板和闸墩结构进行了配筋计算,配筋满足结构要求。(5)进行了截留河北节制闸的总体布置并绘制了北闸总平面图、北闸横剖面图、底板及闸墩钢筋图。
[Abstract]:Because the present situation of the big airport area is relatively low-lying, the river system is developed and affected by the tide, and the facilities of the water conservancy project are not perfect, resulting in frequent flood and waterlogging disasters in the old urban area and deterioration of the river ecological environment. It is necessary to replan the water system of the new area of Da Airport, and to build a sluice at the exit of Hebei Province. The sluice integrates the functions of tide blocking, flood discharge and landscape water storage, and the designed flow rate is 246 m3. In this paper, taking the intercepted Hebei sluice as an example, the detailed design and calculation of the north sluice are carried out after 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 code, The grade of sluice and flood standard are determined, and the ratio of two different schemes is carried out, and the flow conditions, geological conditions, sluice structure, function and economic scheme are considered comprehensively. Finally, the more economical and reasonable sluice types and arrangement schemes are determined. (2) the overcurrent capacity review and energy dissipation and anti-scour facilities design and calculation are carried out, and the energy dissipation facilities such as stilling pool are arranged. (3) for the completion of the construction, The safety and stability calculation of gate chamber is carried out under five different working conditions: water retaining condition, moisture blocking condition, maintenance condition and seismic condition, and the calculated results meet the requirements of anti-skid stability. (4) the reinforcement calculation of sluice floor and pier structure is carried out. The reinforcement meets the structural requirements. (5) the general layout of the intercepted Hebei sluice is carried out and the general plan of the north gate, the cross section diagram of the north gate, the steel bar diagram of the bottom plate and the pier are drawn.
