CS229201B1 - Pilot driving - Google Patents

Abstract

"Driven pile" is used in construction and is a pile with retractable blades and an anchor pile, allowing to transfer considerable loads on light foundation soil. The pile consists of a hollow shaft with holes in all walls, located one above the other, of retractable blades, which are located in the holes, have a bevel on the lower walls and are hingedly attached to the shell by one rib with the possibility of rotation in a horizontal plane, and also of a removable rod with a horizontal outlet at the lower end, which is inserted into the cavity of the shaft during the work. The blades are removed from the shaft hole by turning around the axis of the rod, which is inserted through a horizontal outlet at the lower end into a groove-like cavity between the side walls of the retractable blades. The driven pile is used for the construction of foundations of buildings and various structures in light soils using piles. The essence of the invention is best explained in item 1 of the drawing.

Driven pilot

The stowed pile is used in the construction industry and is a pilot with retractable blades and an anchor pile, allowing to carry a considerable load on light ground. The pilot consists of a hollow shank with openings in all superimposed walls, sliding blades which are located in the openings, have chamfers on the bottom walls and are articulated to the shell by one rib with the possibility of rotation in a horizontal plane, as well as a removable rod with a horizontal outlet at the lower end, which is introduced into the shaft cavity for a period of time. The blades are ejected from the shaft bore by pivoting about a pivot axis which is introduced by a horizontal outlet at the lower end into a groove cavity between the side walls of the retractable blades.

The pile pilot is used to build the foundations of buildings and various structures in light soils using piles.

The essence of the invention is best explained in Figure 1 of the drawing.
