Utilizing "Grout Columns" for Soil Nail Wall Construction
It is well known that earth retention incorporating soil nail construction is unfavorable in soil conditions consisting of sand, gravels, cobbles, and boulders; soils typically encountered in Colorado mountain regions. With the use of "grout columns", a soil nail earth retention system can be utilized in these soil conditions providing a safe method of earth retention while maintaining an efficient construction schedule. Construction, rationale, and benefits of incorporating grout columns in soil nail wall construction are discussed. Specific focus is on "arching" of the soil between grout columns to reduce the loss of soil, enhanced vertical support of the shotcrete face provided by the grout columns while excavating to the next level, and wall movements from a soil nail earth retention project from the Colorado mountain region incorporating grout columns.
