In the refineries, it is becoming common to use the "hydrovac" technique for creating hole for a concrete pier construction. In essence it is water jetting method with high pressure water jet. As the hole excavation progresses, a vacuum hose removes the loosened debris. The method is preferred because it is fast, requires minimum labor, does not create a mess and the excavated material, which is usually defined hazardous, is removed in a compact way for suitable disposal.
Commonly used formulas for determining the vertical and lateral load bearing capacities for the concrete pier assume undisturbed soil. Are there any modified formulas for use with methods similar to "hydrovac"?
Any additional input from list members?
