Abstract
Abstract In a method for compacting compactable soils by vibration while using a compacting apparatus comprising an elongate member having a vibrator mounted on one end thereof, and further having laterally projecting fins arranged along at least part of the length thereof, the elongate member is inserted to a given depth into soil to be compacted and there vibrated to densify and compact soil surrounding said elongate member while withdrawing the elongate member from a compacted location when the load required to lift the elongate member together with the vibrator from said location, while the member is vibrating, is at least equal to a previously established set-point value corresponding to a desired degree of compaction.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
144 words
A method for compacting compactable soils by vibration while using a compacting apparatus comprising an elongate member having a vibrator mounted on one end thereof, and further having laterally projecting fins arranged in use in substantially vertical planes along at least part of the elongate member, said method comprising: a. establishing a set-point value corresponding to a desired degree of compaction of said compactable soils and representing a load required to lift the elongate member from a compacted location while vibrating; b. inserting the elongate member substantially vertically to a given depth into soil to be compacted and vibrating the elongate member to densify and compact soil surrounding said elongate member; and c. withdrawing the elongate member from a compacted location when the load required to lift the elongate member from said location while vibrating is at least equal to said established set-point value.
Claim 2
Independent Claim
144 words
A method for compacting compactable soils by vibration while using a compacting apparatus comprising an elongate member having a vibrator mounted on one end thereof, and further having laterally projecting fins arranged in use in substantially vertical planes along at least part of the elongate member, said method comprising: a. establishing a set-point value corresponding to a desired degree of compaction of said compactable soils and representing a load required to lift the elongate member from a compacted location while vibrating; b. inserting the elongate member substantially vertically to a given depth into soil to be compacted and vibrating the elongate member to densify and compact soil surrounding said elongate member; and c. withdrawing the elongate member from a compacted location when the load required to lift the elongate member from said location while vibrating is at least equal to said established set-point value.
Claim 3
Dependent Claim
39 words
A method according to claim 1, wherein the laterally projecting fins are spaced axially along the elongate member over a length thereof at least substantially equal to the depth to which said member shall be inserted into said soil.
Claim 4
Dependent Claim
23 words
A method according to claim 2, wherein a major part of the compaction is effected as the elongate member is withdrawn while vibrating.
Claim 5
Independent Claim
135 words
A method for compacting compactable soil by vibration while using a compacting apparatus, the method comprising: a. establishing a set-point value for at least one soil location corresponding to a desired degree of compaction of said compactable soils and representing a load required to lift at a given rate the compacting apparatus from a given depth within a compacted location while vibrating; b. inserting the compacting apparatus to said given depth into soil to be compacted in another soil location and vibrating the apparatus to densify and compact soil surrounding the apparatus; and c. withdrawing the apparatus from the compacted location when the load required to lift the apparatus from said location while vibrating is at least equal to said established set-point thereby ensuring that the desired degree of compaction has been met or exceeded.
Claim 6
Independent Claim
135 words
A method for compacting compactable soil by vibration while using a compacting apparatus, the method comprising: a. establishing a set-point value for at least one soil location corresponding to a desired degree of compaction of said compactable soils and representing a load required to lift at a given rate the compacting apparatus from a given depth within a compacted location while vibrating; b. inserting the compacting apparatus to said given depth into soil to be compacted in another soil location and vibrating the apparatus to densify and compact soil surrounding the apparatus; and c. withdrawing the apparatus from the compacted location when the load required to lift the apparatus from said location while vibrating is at least equal to said established set-point thereby ensuring that the desired degree of compaction has been met or exceeded.
