摘要
支护工程换撑时需考虑施工过程中对周边环境的影响及基坑支护安全等问题,由于项目地下室施工区域和内支撑区域的交叉较多,各区施工结束时,受相邻分区进度的干扰,无法拆除对应的内支撑,影响地下室结构流水施工,延长施工工期.以宝安区某项目为例,通过设置悬挑支撑结构,对未施工区进行提前支撑,解决了分区进度不一无法拆除内支撑的问题,后续无需拆除,达到了永临结合的效果.
Abstract
The impact on the surrounding environment and the safety of foundation pit support in the construction process should be considered when the support project is replaced.Because there are many crosses between the construction area and the inner support area of the project basement,the corresponding inner support cannot be removed at the end of the construction due to the interference of the progress of adjacent zones,which affects the flow construction of the basement structure and prolongates the construction period.Taking a project in Bao'an District as an example,by setting a cantilever support structure,the non-construction area is supported in advance,which solves the problem that the internal support cannot be removed due to the different progress of the zoning,and there is no need to remove it later,achieving the effect of combining permanent presence.
