Abstract
A method for lowering a basement structure includes forming several upright pile holes in the ground, providing each of the pile holes with a pile, providing several vertical guide holes and an excavation passage which are formed through the basement structure in such a manner that the guide holes are aligned with the pile holes, equipping each of the guide holes with an impelling device which is coupled with one of the piles, excavating soil below the basement structure, and activating the impelling devices to lower the basement structure into the ground in such a manner that the piles extend through the guide holes. Several vertical steel rods are embedded in each of the piles. Each of the impelling devices includes an upright cylinder body fixed on the top end of the basement structure, a piston rod extending through the cylinder body, and a piston carried on the piston rod. An internally threaded engaging member is engaged with the externally threaded lower portion of the piston rod. Several coupling bar units interconnect securely the engaging member and the upper ends of the steel rods. Each of the coupling bar units includes several bar sections arranged in a line and several collars detachably interconnecting the bar sections. A rotary lever unit is secured to the piston rod.
