摘要
地连墙加钢筋混凝土支撑的基坑,支撑结构与主体结构冲突,底板施工时进行立柱桩托换。因无法按原设计方案进行新增立柱桩施工,通过在承台底部位置增加条形基础,基础顶部进行钢管吊装回顶,底部灌浆浇筑密实,支撑梁底搭设钢管吊架供施工人员进行钢柱固定等操作,成功地解决了新增立柱桩无法按原设计用旋挖钻机施工等问题,从而为类似工程提供借鉴。
The foundation pit with reinforced concrete braces and the supporting structure are in conflict with the main structure. The new column pile construction can not be carried out according to the original design scheme. By adding the strip foundation at the bottom of the cap, the steel pipe is hoisted back to the top at the top of the foundation, the bottom grouting is dense, the steel pipe hanger is set up for the construction personnel to fix the steel column, and the new column pile can not be designed according to the original design. Some problems such as the construction of rotary drilling rig and so on, thus providing reference for similar proiects.
