Considering that micropiles are bonded into the rock socket wall, they do not depend upon end-bearing capability and there is no will need to establish competency of rock further than bond-depth. They can be set up promptly in pretty much each kind of ground working with highly adaptable cell drilling equipment. These metal ความแตกต่างระหว่างเสาเข็มไมโครไพล์กับเสาเข็มอื่นๆ piles typically have working capacities as much as 250 tons.

When challenging site situation and style standards exist, micropiles tend to be Utilized in conjunction with other floor modification methods.

For the softening and collapse of soil caused by solid rainfall while in the rainy period, the self-drilling anchor bolt design work area is small and there is no have to excavate and take away the soil utilized for counter-pressure.
