浅谈外海大潮差地区水下大型软体排铺设工艺的改进

Improvement on Laying Technology of Underwater Large-scale Soft Mattress within Open Sea Macro-tidal Range Area

以南通洋口港区人工岛围堤工程为例,介绍水下大型软体排的组成结构、材料选取和设计方法的要点,并重点探讨如何改进在复杂工况条件下铺设水下大型软体排的施工工艺和船机配备。实践证明,改进后的软体排铺设工艺与传统施工工艺相比,既提高了施工效率,又确保了工程质量。

The retaining dike project of man-made island in Nantong Yangkou Port Area is taken as an instance to introduce the structure,material selection and design method of underwater large-scale soft mattress.In addition,it is discussed as an important issue the method to improve the construction technology and ship machine allocation for laying underwater large-scale soft mattress under complicated work conditions.The practice shows that the improved soft mattress laying technology can raise construction efficiency and guaranteed project quality in comparison with the traditional technology.
