船闸扩建工程的施工导流标准和围堰方案
|
摘要
针对已建枢纽扩建船闸工程施工围堰标准的问题,结合株洲二线船闸工程对围堰的双重使用功能进行分析,其施工围堰应分区确定围堰标准,并在充分权衡导流设施建设成本与降低标准造成损失的基础上,妥善安排度汛、排水措施,将对工期的影响降到最低。同时总结了船闸扩建工程施工导流特点、围堰设计目标、过水围堰度汛时的主要工程措施,为航电枢纽船闸改扩建工程的布置和围堰设计提供参考。
Aiming at the construction cofferdam standard of ship lock expansion project,we analyze double functions of the cofferdam based on Zhuzhou second ship lock project. The standard of cofferdam should be determined for different regions. Based on fully balancing the construction cost of diversion facilities and the loss caused by reducing standards,the flood control and storm water drainage are appropriately implemented to minimize the impact on the duration of the project.Meanwhile,we summarize the characteristics of construction diversion,the design targets of the cofferdam and the flood control measures,which can provide references to new arrangement schemes and cofferdam design for ship lock expansion project.
