随着城市建设的快速发展,深基坑工程越来越普遍。在内支撑型深基坑工程施工过程中支撑拆除是广泛存在的一个施工过程,即采用换撑技术解决支护由于内支撑拆除所导致的稳定问题,使基坑支护在新的条件下重新建立平衡。现在越来越多的深基坑工程开始使用短斜钢支撑作为换撑使用,经过实践证明短斜钢支撑作为换撑使用方法简单有效,效果显著,在工程中具有良好的适用性。
With the rapid development of urban construction, deep foundation pit projects are becoming more and more common. During the construction process of the deep foundation pit with internal support, the support and dismantlement is a widespread construction process, that is to say, the support technology is adopted to solve the stability problem caused by the support removal due to the inner support, so that the support of the foundation pit is restarted under the new conditions Build balance. Nowadays more and more deep foundation pit projects begin to use the short inclined steel support as a replacement support. The practice of using the short inclined steel support as a replacement support has been proved to be simple and effective with significant effects and has good applicability in engineering.
