小郭巨二期围垦工程临时河道浮运式箱涵水闸设计

Floating Sluice Box Culvert Design of Temporary River in Xiaoguoju Phase II Reclamation Engineering

小郭巨二期围垦工程,因围垦初期内陆养殖需要,需在临时河道上新建3座养殖排水闸。结合工程点实际情况,设计采用浮运式水闸结构形式。由于在施工中采用浮运、沉放等水中施工技术,对防渗、抗滑要求高。因此在设计过程中,针对地基基础处理、闸门结构等进行了重点设计。浮运式水闸作为一种新闸型,由于不设围堰,节约了工程投资,在沿海地区具有一定的推广、应用价值。

Due to the initial inland aquicuhure needs, Xiaoguoju phase II reclamation project needs to build three new breeding drainage sluices on the temporary river. Combining with the practical situation of engineering point, the design adopted floating sluice structure form. As water floating, sinking and other construction technologies were used, the project demanded high standard for seepage control, and sliding resistance. Therefore, in the design process, we focused on the design of foundation treatment and gate structure. As a new type gate, floating sluice gate doesn＇t set cofferdam, thus saving the project investment.
