后增塔吊在已施工完成结构的基础、附墙施工技术

Construction Technology of Post Added Tower Crane on the Foundation and Attached Wall of the Completed Structure

地下室结构已施工完成,主体已部分施工,项目为保障进度需额外新增塔吊的情况下,通过采用定位于地下室顶板已施工完成结构的钢结构塔吊基础及抱柱附墙的施工技术,避免了传统的钢筋混凝土基础及墙柱打孔附墙等需破拆已施工完成结构的施工方式,可最大限度地保护已施工完成的结构并提高后增塔吊的安装效率。

The basement structure of the project has been completed,the main body has been partially constructed,and the project needs to add additional tower cranes to ensure the progress,this project uses the construction technology of steel structure tower crane foundation and holding column attached wall positioned on the completed structure ofthe basement roof to avoid the traditional reinforced concrete foundation,wall column drilling attached wall and other construction methods that need to demolish the completed structure.It can protect the completed structure to the greatest extent and improve the installation efficiency ofthe later added tower crane.
