Benefits of Cased Micropiles for Soil Stabilization
Enhanced Load Transfer: Utilizing the combination of casing, grout, and reinforcement to enhance load transfer capabilities. The steel casing provides additional strength and stability, while the grout and reinforcement contribute to the load-bearing capacity. This enhanced load transfer allows cased micropiles to effectively transmit loads through weak soils to stronger underlying strata.
Mechanisms for Transferring Axial, Tensile, and Shear Loads: Designed to transfer different types of loads, including axial, tensile, and shear loads. The steel casing, filled with grout and reinforcement, acts as a column element with significant axial capacity. It provides resistance against compressive forces and ensures the stability of the micropile. Additionally, the grout-filled steel casing offers greater shear capacity compared to other micropiles, making it suitable for resisting lateral forces and shear loads.
Increased Depth Capabilities: Depending on various factors such as soil stiffness, casing diameter, wall thickness, and steel strength, cased micropiles can extend to depths of up to 250 feet. This increased depth capability allows for the installation of cased micropiles in deeper soil layers or when encountering challenging soil conditions. It provides flexibility in designing foundations for projects that require deeper support.
