经过近一年的紧张建设,东河水利枢纽主体工程之一的船闸工程于日前顺利通过初步验收,7月23日举行了简朴、隆重的技术性试通航仪式,标志着这座总投资2亿元的全市最大水利工程开始发挥防洪和通航作用,同时为整个工程特别是泵站的顺利建设奠定了坚实基础。船闸工程是东河水利枢纽的一个主要组成部分,按内河Ⅳ级航道、通航500吨级设计,闸首净宽16m,船闸长120m,设计年通航量1000万t。工程自1998年8月5日动工以来,克服了深层淤泥施工、钢板围堰防渗、大规格沉井、水下深层淤泥钻桩和施工场地工作面少等诸多难题,于1999年6月30日竣工,历时325天,共完成土方
After nearly a year of intense construction, the Lock Project, one of the main projects of Donghe River Water Control Project, successfully passed the preliminary acceptance and acceptance recently. On July 23, a simple and solemn technical trial pilot ceremony was held, marking a total investment of 200 million yuan The city’s largest water conservancy project began to play a flood and navigation role, at the same time for the entire project, especially the smooth construction of the pumping station has laid a solid foundation. The ship lock project is a major component of Donghe River Water Control Project. According to the Grade IV navigation channel of the inland river, it is designed to be 500-ton navigable and has a net opening width of 16m and a lock of 120m. The designed annual navigation volume is 10 million tons. Since the construction started on August 5, 1998, it has overcome many difficulties such as deep silt construction, seepage prevention of steel cofferdam, large size caisson, deep submerged silt drilling pile and less working face of construction site. Since June 30, 1999, Completed on the day, which lasted 325 days, completed a total of earth
