A METHOD FOR HIGH CAPACITY STONE DELIVERY WITH CONCENTRIC FLOW AND ENHANCED NOSECONE FOR SOIL IMPROVEMENT

摘要

A method for measuring the volume of a material discharged and the depth over which the material is discharged into a soil to create a column. Wherein the system comprised of the hopper, the stone chamber, the stone feed pipe, the transition splitter pipe, and the vibratory probe mechanism are all connected and suspended from a main winch of a crane; wherein the stone chamber is pressurized, the operator begins to lowering the vibratory probe mechanism into the soil to the design depth to create a cavity; wherein the pressurized stone is transported to the outlet chutes at the tip of the vibratory probe mechanisms; wherein the vibratory probe mechanism is raised to a predetermined height to allow the material to fall into the previously created cavity; wherein a sensor in the stone chamber measures the quantity of material released into the cavity; wherein the amount of re-penetration into the previously placed soil is determined either by reaching a pre-determined diameter of a column or by reaching a predetermined density as measured by the amount of energy applied to the vibratory probe mechanism; and whether the diameter or energy is controlling the process, the controlling parameter is calculated in real time and displayed on the operators screen in the cab of the crane.
