人字闸工程技术应用与实践

The Application and Practice of Miter Gate Engineering Technology

对人字闸的适用条件及特点进行了分析,详细阐述了人字闸规划设计、施工以及运行管理的方法,并介绍了人字闸的各方面效益。人字闸是一种适用于浅山丘陵地区小型河道之中的蓄水工程,其特点是安装拆卸方便灵活,投资小、设计施工简单易行、运行管理方式多样。规划设计阶段利用相关来用水资料计算库容和闸前水深,确定人字闸的结构形式,计算闸板和支架的配筋。施工过程中应重点注意清基和防渗处理,运行管理时要做好汛前检查中的相关问题。人字闸同时具有经济、防洪和生态效益。结合已建的工程实例,详细介绍了人字闸的规划设计过程。

Applicable conditions and characteristics of miter gates are analyzed while planning and design, construction, operation management, the benefits of miter gates are elaborated. The miter gate is suitable for small river water storage projects in hilly re- gions, whose characteristics are flexible and convenient for installation and disassembly, small investments, simple to design and op- erate, and various operation management modes. In the planning and design stage, water storage capacity and depth before gates are calculated by using relevant water data, the structure of miter gate is determined, and reinforcement of gates and supports is also cal- culated. In the construction process clearing base and anti-seepage treatment, as well as the related issues of the pre-flood inspections should be focused on. Miter gates could provide the benefits of economy, flood control and ecology. The design process of miter gates is introduced in detail according to the constructed project.
