近岸深水联排灌注桩施工工艺优化

采用传统的冲孔灌注桩施工工艺进行海上灌注桩施工时,往往会面临适用条件限制、环境污染、施工成本增加等问题。针对三亚凤凰岛项目海上冲孔灌注桩施工特点,介绍通过优化钢平台结构形式及布局设计、泥浆循环系统优化设计、结构稳定性计算、"四新设备"创新应用等措施,有效降低施工成本、提高施工效率、减少环境污染、提高施工质量。结果表明采取的工艺优化和平台改进措施效果良好、实用性强。

Optimization of construction technology on ultra-deepwater nearshore continuous cast-in-place pile

If traditional technology of punched cast-in-place piles is used on water,we will meet some difficulties,such as limitations of applicable conditions,environmental pollution and cost increment.Depending on the characteristics of Sanya Phoenix Island project,we expound measures of reducing production cost,reducing pollution,improving the construction efficiency,improving construction quality by optimizing the structure type and layout design of steel platform,optimizing design of mud circulation system,structural stability calculation and application of new equipment.The results show that the measures of technology optimization and platform improvement are effective and practical.
