随着我国经济建设的不断发展,跨越大江大河甚至海湾的桥梁也越来越多。水中墩系梁施工,在航道不允许进行筑岛施工时,还可以选择的施工方法有钢板桩围堰、混凝土围堰、钢套箱围堰、钢-混凝土组合结构围堰。每种围堰都有自己的特点和适用条件,因此需要根据各自的水文、地质、材料价格以及设备情况等必选而定。本文以丹东港临港产业园区1#公路桥工程水中系梁钢套箱施工为例,介绍异型钢套箱围堰施工,为类似工程的施工提供有益经验。
With the continuous development of our country’s economic construction, more and more bridges span great rivers and even the gulf. In the water pier girder construction, in the channel is not allowed to build the island construction, you can also choose the construction methods are steel sheet cofferdam, concrete cofferdam, steel box cofferdam, steel-concrete composite structure cofferdam. Each type of cofferdam has its own characteristics and conditions, and therefore needs to be based on the respective hydrology, geology, material prices and equipment requirements. In this paper, the construction of beam steel box for water system of No.1 # highway bridge in Dangang Port Lingang Industrial Park is taken as an example to introduce the construction of cofferdam of special-shaped steel box cofferdam and to provide useful experience for the construction of similar projects.
