Design and execution of retaining-walls using the reinforced jet-grouting technique
This article presents a solution for the design and construction of reinforced jet-grouting structures. In particular, it discusses the application of reinforced jet-grouting for retaining walls in excavations for basement construction. The use of jet-grouting as a structural element with flexural work is not common, as this product is typically used almost exclusively under pure compression. Flexural forces require the reinforcement of this material with steel bars, and the use of a finite element model is presented as a possible design tool for this purpose. The work described was successfully completed using the concept of reinforced jet-grouting with corrugated steel bars. Additionally, the article outlines the specific procedure for performing jet-grouting in a complex colluvial geology with large, embedded rock blocks in a heterogeneous granular matrix, making it challenging to create ideal intersecting cylindrical jet-grouting columns.
