Immersed tube anchor block construction method
The invention discloses a construction method of an immersed tube anchor block. The construction method comprises the following steps: driving a steel sheet pile: driving and arranging the steel sheet pile on the shore to support a foundation pit; foundation pit excavation, wherein anchor block foundation pits are excavated according to design; a broken stone hardcore layer is laid, wherein the broken stone hardcore layer is thrown and filled after the foundation pit is excavated; cofferdam construction is conducted, specifically, membrane bag sand cofferdam construction is conducted; water pumping in the cofferdam: pumping out accumulated water in the cofferdam; reinforcing steel bars are bound, wherein anchor block reinforcing steel bars are bound after the pipe joint is installed and is in butt joint with a shore pipeline; formwork installation, wherein a formwork for anchor block pouring is installed; concrete pouring: pouring a concrete anchor block by using a template support; after the anchor blocks reach the strength, the formworks are dismantled; and backfilling the foundation pit and removing the cofferdam. And the immersed tube anchor block construction can be quickly and efficiently completed.
本发明公开了一种沉管镇墩施工方法，包括钢板桩施打：在岸上施打布置钢板桩进行基坑支护；基坑开挖：按照设计开挖镇墩基坑；碎石垫层铺设：基坑开挖好后抛填碎石垫层；围堰施工：进行膜袋砂围堰施工；围堰内抽水：抽出围堰内的积水；钢筋绑扎：待管节安装完成并与岸上管线对接完后，进行镇墩钢筋绑扎；模板安装：安装镇墩浇筑用的模板；混凝土浇筑：利用模板支撑浇筑混凝土镇墩；模板拆除：镇墩达到强度后，拆除模板；基坑回填并拆除围堰。能够快速高效的完成沉管镇墩施工。
