Where by granular soils are encountered micropiles may be set up using simultaneous drilling and grouting with hollow reinforcing the place the grout is pumped from the reinforcing given that the micropile is Superior to depth.
To ensure that adequate depth is delivered, it is required to examine the consistency of spoil. Furthermore, it is needed to practice excellent cautions all through uninteresting and concrete placement to circumvent undesired consequences of these functions. 4.3 Operating Load Faults in Mechanically Augured Piles
