CONSTRUCTION APPLICATION OF STEEL-MIXED INTERNAL BRACING IN DEEP FOUNDATION PIT SUPPORT ENGINEERING
In the construction of large-scale deep foundation pit support engineering,the internal support system usually adopts the concrete internal support system,but the concrete internal support has the disadvantages of large waste of resources,slow construction period and high support cost.Based on the comparison and selection of the design scheme of the internal support combined with concrete internal support and the application analysis of the construction technology of the internal support combined with steel concrete support for a certain project,this paper expounds the important role and advantages of the internal support combined with steel concrete support in deep foundation pit support engineering,in order to provide reference for the construction of relevant deep foundation pit support engineering.
