Abstract
A foundation structure using a micro pile and a method of forming the same. A cover steel plate is disposed at an upper end of the micro pile, and has a micro pile hole. The micro pile is connected with others in series thanks to the use of two through eight protrusions formed on a lower end thereof. Grout or concrete is injected into a hollow channel of the micro pile, and enhances a conglomerating force between the micro pile and the ground abutting the micro pile to thereby strengthen the force supporting the ground in the vertical and horizontal directions.
Claims6
A foundation structure using a micro pile, in which:
- a cover steel plate including a micro pile hole is fitted around an upper end of the micro pile;
- bolt holes formed in the cover steel plate are spaced apart from the micro pile hole by a predetermined distance, into which bolt holes are inserted bolts via and through washers, wherein each bolt has a length equal to a distance from the upper end of the micro pile to intermediate discharge holes of the micro pile;
- an upper joint is formed with two through eight cylinders on the upper end of the micro pile, and a lower joint is formed with two through eight protrusions on a lower end of the micro pile so as to be engaged with the upper joint;
- the lower joint has half a length of the upper joint, and the micro pile is connected with others in series so as to reinforce ground;
- and
- grout or concrete is injected into a hollow channel of the micro pile, discharged through the intermediate discharge holes and joint discharge holes, and penetrates into the ground abutting the micro pile such that the micro pile becomes conglomerated with the ground.
A foundation structure using a micro pile, in which:
- a cover steel plate including a micro pile hole is fitted around an upper end of the micro pile;
- nut holes are formed in the cover steel plate spaced apart from the micro pile hole by a predetermined distance, and T-shaped nuts are screwed onto protrusions of an upper joint inserted into the nut holes of the cover steel plate;
- the upper joint is formed with two through eight cylinders on the upper end of the micro pile, and a lower joint is formed with two through eight protrusions on a lower end of the micro pile so as to be engaged with the upper joint;
- the lower joint has half a length of the upper joint, and the micro pile is connected with others in series so as to reinforce ground;
- and
- grout or concrete is injected into a hollow channel of the micro pile, discharged through the intermediate discharge holes and joint discharge holes, and penetrates into the ground abutting the micro pile such that the micro pile becomes conglomerated with the ground.
