Abstract:
A method and a mandrel for forming a cavity at a target location. The mandrel may include a main drilling shaft, a plurality of T-shaped elements, a hollow-cylindrical-shaped element, and a plurality of parallelepiped-shaped stiffener plates. The main drilling shaft may include a hammer insertion part positioned at a first end of the main drilling shaft, a bore head positioned at a second end of the main drilling shaft, and a medium part positioned between the hammer insertion part and the bore head. The plurality of T-shaped elements may be mounted adjacently around the medium part in a way such that forming a closed octagonal from a top-view of the mandrel. A first size of a first cross-section at a first location from a top-view of the plurality of T-shaped elements around the medium part may be larger than a second size of a second cross-section at a second location from the top-view.

Claim (Index 1):
1 - A mandrel for forming a cavity at a target location, the mandrel comprising:\n a main drilling shaft comprising a cylindrical-shaped structure, the main drilling shaft comprising:\n a hammer insertion part positioned at a first end of the main drilling shaft; \n a bore head positioned at a second end of the main drilling shaft, the bore head being configured to tamper through hard rock surfaces; and \n a medium part positioned between the hammer insertion part and the bore head; \n a plurality of T-shaped elements mounted adjacently around the medium part, the plurality of T-shaped elements forming a closed octagonal from a top-view of the mandrel, wherein:\n a first size of a first cross-section at a first location from a top-view of the plurality of T-shaped elements around the medium part is larger than a second size of a second cross-section at a second location from the top-view, the first location closer to the hammer insertion part and the second location closer to the bore head; and \n each respective T-shaped element of the plurality of T-shaped elements comprising:\n a first trapezoid-shaped plate comprising a trapezoid face; and \n a second trapezoid-shaped plate comprising a first edge and a second edge, the second trapezoid-shaped plate attached at the first edge of the second trapezoid-shaped plate to the trapezoid face of the first trapezoid-shaped plate; \n \n a hollow cylindrical-shaped element mounted onto the main drilling shaft, the hollow cylindrical-shaped element comprising:\n a main drilling shaft insertion hole; \n a hollow-cylindrical section comprising a top surface and a bottom surface; and \n a hollow-beveled section comprising a large-diameter circular surface and an outer beveled surface, the hollow-beveled section attached at the large-diameter circular surface to the bottom surface of the hollow cylindrical section; and \n a plurality of parallelepiped-shaped stiffener plates mounted around the medium part of the main drilling shaft, each respective parallelepiped-shaped stiffener plate of the plurality of parallelepiped-shaped stiffener plates comprising a third edge and a fourth edge, each parallelepiped-shaped stiffener plate of the plurality of parallelepiped-shaped stiffener plates attached at the respective third edge to the outer beveled surface of the hollow-beveled section and attached at the respective fourth edge to the medium part of the main drilling shaft.
