Method for increasing the end-bearing capacity of open-ended piles
Patent
·
OSTI ID:7191484
This patent describes a method for insuring fill mobilization of the end-bearing capacity of an open-ended pile, the pile being substantially vertical and being driven into the earth such that a soil column is formed in the lower end of the pile. It comprises determining the quantity of a loose, unagglutinated, granular material which will lock-up, without cementation, within the pile during loading of the pile and thereby insure full mobilization of the available capacity of the soil at the tip of the pile, and inserting at least the quantity of the granular material into the pile on top of the soil column.
