摘要
金融街(南开)中心工程,其基坑面积及土方开挖量大,施工场地狭小,施工周边环境复杂,降水及土方开挖施工困难。通过在第1道内支撑上设置栈桥作施工道路,解决土方开挖及地下结构施工的交通运输问题;分区分段进行降水、土方开挖,降低了施工难度、加快了施工进度;基坑施工过程中实行全方位的基坑监测,保证了超大面积深基坑施工安全。
Combined with actual project, the construction of foundation excavation is difficult because of large area and soil excavation, narrow construction site, complex environment, et al. By setting trestle on the first inner support as the construction road, the problems for soil excavation and transportation are resolved, the dewatering and soil excavation by zoning and segmentation reduced the construction difficulty and quicken construction pace. By the omnidirectional monitoring on foundation excavation, the safety of foundation excavation is ensured.
