船户周民常年驾船往返于张家港与靖江之间，新枢纽的投用带来切实利好。"我的船比较宽，以前 老闸过不去，只能绕行，一绕就要多走几十公里。赶上船多的时候，走一趟花个两三天也不稀奇，时间 和油钱都耗不起。现在的新闸够宽，可以直接过，当天就能把货送到，效率高多了。" 十一圩江边枢纽是张家港水利建设史上单体投资规模最大的水利枢纽，工程总投资约4.7亿元， 2022年5月启动改建，不久前正式建成投用。 该枢纽主要由节制闸、泵站和套闸三部分组成。其中，节制闸共三孔，总净宽28米，具备挡潮、排 涝、引水及通航功能；泵站设计排涝流量达60立方米/秒，可在强降雨时启动强排；套闸的闸室规模显 著扩大。"新套闸有效改善通航条件，"张家港市长防处十一圩所所长施江峰介绍，"闸室长度从原来的 160米增至180米，宽度从18米增至23米，单次过闸船只由4艘增加到6艘，通行效率大幅提升。节制闸目 前已投入日常运行，每天根据潮位排水1至2次，汛期能有力缓解内河涝情。" 昨天（12月12日），记者来到张家港市十一圩江边枢纽。随着绿灯亮起，在闸外等候的多艘货轮缓 缓启动，按照指令有序进闸，现场繁忙而有序。 据了解，十一圩江边枢纽在完善功能的同时，还 ...
