At GeoStabilization International®, we are leading excavation shoring contractors in Commerce City, CO, and operate throughout the United States, Canada, and Australasia. Our cutting edge SuperMicropiles™ foundations allow economic shoring wall construction and provide optimal support in any subsurface environment.
A micropile is a reinforced non-displacement pile with a relatively small diameter of less than 12 inches. The construction of a micropile involves:
Micropiles can withstand moderate lateral and significant axial loads and are a viable alternative to conventional drilled shafts or driven piles. These temporary supports are ideal for improving shoring wall stability for excavation, especially in suboptimal soil conditions. Micropiles provide superior open-cut face or soil nail wall support, ensuring optimal deflection control.
Reinforced concrete provides the structural load resistance of conventionally drilled piles. Increasing the structural capacity of these piles involves increasing their cross-sections and surface areas. On the other hand, high-capacity steel components provide a micropile’s structural load resistance, and these elements only occupy up to 50% of the drill hole cross-section.
Due to micropiles’ lower space requirements, designers can use them to construct shoring systems in narrow corridors or shoring zones that provide limited access to large drilling equipment. Micropile installation causes minimal disturbance to the surrounding environment, soil, and structures, and the drilling screws and installation process don’t cause excessive noise or vibrations.
At GeoStabilization International®, we use micropiles to reinforce soil masses utilizing reticulated micropiles. These micropiles are layout in the form of secure networks of micropiles. During a reservoir expansion project in Saskatchewan, our engineers developed a reticulated SuperMicropile™ foundation to establish a reinforced soil composite as temporary shoring. This reticulated micropile network provided optimal support and stabilization during the construction of a reservoir and pump house.
In the case of a reticulated micropile network, the structural load applies evenly to the entire solid mass or surcharge. In conventional arrangements, each micropile carries the lateral or vertical load directly. Consequently, the micropiles in an individual arrangement have a relatively high capacity with a steel rod or casing reinforcement. A reticulated network consists of lower-capacity micropiles to internally reinforce and delineate soil volumes.
Self-drilling micropiles are the ideal components of a reticulated micropile network. Unlike conventional piles, self-drilling micropiles allow for optimal installation flexibility.
Since a micropile installation doesn’t disturb the surrounding environment, reticulated micropile networks retain the soil to form one composite gravity structure. In other words, the soil provides the weight, and the micropiles provide the reinforcing elements.
This soil-micropile interaction optimally supports compression, shear stress, and tension. The applications of a reticulated micropile network include:
