Soil densification system and method

摘要

A soil densification system and method is disclosed. The presently disclosed soil densification system includes an air delivery probe or pipe that can be driven or otherwise installed into a soil mass. An inlet of the air delivery probe is supplied by an air compressor and an air storage tank, which are used for the rapid delivery of air impulses or bursts into the air delivery probe, whereas the air impulses or bursts are expelled out of an outlet of the air delivery probe and into the soil mass. The method of using the presently disclosed soil densification system includes the steps of inserting the end of the air delivery probe into the soil mass to any desired depth and then releasing an impulse or burst of air into the soil mass, thereby forming a densified region in the soil mass via the forces of the air impulse.

主权项

1. A method of densification of a soil mass, comprising:
a. providing an apparatus for controlled air soil densification, comprising:
1) a primary tube having an upper portion and a lower end portion;2) one or more ports formed in the primary tube at the lower end portion; and3) a pressurized air system connected to the primary tube, wherein the pressurized air system further comprises a stored volume of air connected to an air source, the pressurized air system configured to deliver controlled air bursts into the primary tube and configured to deliver controlled air bursts into the soil mass; b. inserting the end portion of the primary tube to a desired soil treatment level depth in the soil mass; c. releasing an air impulse at the one or more ports to form a void surrounded by a zone of densification; d. maintaining the lower end portion of the primary tube at the desired soil treatment level depth in the soil mass while releasing the air impulse; e. filling the void in the soil mass created by the air impulse at the one or more ports with flowable media via the primary tube.
