南水北调中线工程节制闸大开度检验调度方案
|
摘要
南水北调中线沿线设有64座节制闸,为确保金结机电设备运行安全,按照设施设备规范要求各节制闸应在动水条件下进行零开度至全开度检验。中线工程现处于通水初期,沿线各分水口门尚未达到设计流量,如需完成大开度检验,势必需要通过采取一定的调度措施来实现。结合中线工程运行实际,选取典型试点分析大开度检验的可行性;同时在充分考虑目前全线小流量、高水位的运行状态下,比对分析几种特定条件下的运行调度方案,初步研究选取了"控制闸调整局部渠段水位"的调度方案。通过对试点节制闸上下游控制建筑物的运行水力条件进行调整,保持试点节制闸目标过闸流量及其上下游渠段水位的相对稳定,进而实现节制闸大开度检验。
The Middle Route Project(MRP)of South-to-North Water Diversion(SNWD)has 64 check gates.The check gates need to be tested under the flowing water from zero to the maximum opening to ensure the safe operation of the SNWD project.Certain operation measures need to be taken in order to complete the maximum opening test when the dividing gates have not yet met the design discharge.This article analyzed the feasibility of a maximum opening test based on a typical check gate,and compared the operation scheme across several specific conditions.After preliminary study,it selected the scheme of " adjusting the water level of local canal reaches with control gates",where the hydraulic conditions of upstream and downstream control structures of the piloting check gate were adjusted to ensure relatively stable water supply and water level at the piloting check gate and the upstream and downstream canal reaches,thus realizing the maximum opening test.
