直立式防波堤桶式结构浮运安装
|
摘要
连云港徐圩港区直立式防波堤工程采用一种新型桶式结构,为了解决该结构的海上运输与安装,节省施工费用,施工中采用水上气浮拖带运输,通过排气、排水实现负压下沉,保证了新型桶式结构的顺利实施。在桶式基础结构气浮拖运和负压下沉过程中,通过自动控制系统控制桶式基础结构的姿态和沉放精度,保证了工程质量。
A novel bucket-based structure is used in the construction of the Xuwei upright breakwater in Lianyungang. In order to resolve the marine transportation and installation problem and save construction cost, the pneumatically floated bucketbased structure is towed by tugboats and installed with negative pressure, thus ensuring the smooth transportation and installation of the bucket-based structure. According to process requirements, the automatic control system is used to control the rise and lowering of the bucket type structure with correct positioning and accuracy during the towing of the pneumatically floated bucket-based structure and the installing of the bucket-based structure with negative pressure to ensure the quality of the works.
