防波堤箱筒型基础结构气浮拖运与负压下沉工艺

Technology for Towing of Pneumatically Floated Cylindrical Substructures and Installing with Negative Pressure for Breakwaters

以天津港箱筒型基础防波堤试验工程为例,介绍了防波堤箱筒型基础新结构及基础结构气浮拖运和负压下沉的新工艺,实践证明:这种国内首次开发的新工艺,安全可靠,耗能少,操作简单,适用于淤泥质地质条件下的防波堤、导堤及护岸工程。

Based on the pilot works for the breakwaters built on cylindrical steel structures for Tianjin Port, the paper presents an introduction to a new structure of breakwaters built on cylindrical structures and a new technology for towing pneumatically floated cylindrical structures and installing the cylindrical structures with negative pressure. The engineering practice proved that the new technology, which is the first that has been ever developed in China, is safe and reliable, low in energy consumption and easy to operate, thus applicable to breakwaters, levees and revetments built on mucky soils.
