短斜钢支撑换撑施工技术

Construction Technology to Replace Short Angle Steel Support

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,实践证明短斜钢支撑作为换撑使用方法简便有效,收效明显,在工程中具有良好的适用性。

With the rapid development of city construction,the deep foundation pit engineering is more and more general.The support demolition in the engineering construction process of inner-supported deep foundation pit widely exists in a construction process.The support replacing technology is used to solve the stability problem of support caused by the demolition of inner support so as to make the support of foundation pit rebuild the balance under the new condition.At present,the short angle steel support as the support replacement is started to use in more and more projects of deep foundation pit.The practice has proved that the short angle steel support as the support replacement method is simple,convenient and efficient.Its effective effect is obvious.There is a good applicability in the projects.
