Structure Connections and Wall Tie-Ins for Cutoff Wall Construction
In the framework of the Herbert Hoover Dike Rehabilitation project, BAUER Foundation Corp. has been tasked with the installation of 17.6 mi (28.3 km) of seepage cutoff wall distributed over three task orders. The cement deep soil mixing method of cutter soil mixing (CSM) is being used to install the wall. Challenging ground conditions such as organic soils and limestone and sandstone layers found in large portions of the project require a pretreatment of the foundation soils. This is performed via replacement borings applying cased Kelly drilling techniques or via pre-drilling using continuous flight augers (CFA). A special focus is put on tie-ins of new wall into existing cutoff wall segments and connections of new wall to existing structures via jet grouting.
