With the breakwater construction to the extension of the deep-water segment of soft soil foundation for poor physical and mechanical indexes of the seabed surface and shallow soil , domestic and foreign construction box cylinder breakwater , the structure itself is not a pouring from sealing is not easy to achieve , the need to install large-scale construction equipment , construction efficiency lower cylinder by its own weight and imposed loads sink to the design elevation appears cylinder deviation and difficult correction . This article describes a plug-in box bucket foundation breakwater structure construction technology, the single cylinder prefabricated precast plant , the concrete pouring once in place, not facilities industrial sewing , and then splicing assembly . Inflatable float infrastructure tugboat towed to the construction site , the use of its own structure through the headstock setting in the underlying roof structure in different parts of the drain pump to adjust its sink rate , can be effectively leveling corrective control (elevation , tilt, deviation ) sink, easy operation . Then floating crane lifting the the tank barrel member upper cylinder and infrastructure connected . Box bucket foundation breakwater structure take full advantage of the soft soil cohesion and frictional resistance to ensure that the structure of the anti-slide and anti - roll stability , improve the insertion depth of the bearing capacity and overall stability of the base . The large amount of data obtained during the observation period , by the construction of this technology , the structure is stable . In China's coastal areas , there are plenty of soft soil seabed ground , such as the Tianjin Port waters near the estuary of the Yangtze River , the Pearl River Estuary , these estuarine waters is a large hub port is located , with the further development of the national economy , Minato there will be a lot of deep breakwater will be constructed using plug-in box barrel infrastructure construction deepwater breakwater obvious economic benefits , the construction process is simple , with strong market competitiveness , has a broad application prospects .
