(54)	Method and pile-driving device for inserting foundation piles into the ground

(57) Method for inserting foundation piles into the ground, comprising the steps of positioning at least two telescopically connected pipe segments above a base plate, moving a pile-driving hammer up with a pile-driving device, moving the pile-driving hammer down through the pipe segments, and letting the pile-driving hammer ram the base plate and at least one of the pipe segments.
The invention is characterized in that the method furthermore comprises the steps of withdrawing the pipe segments from the ground using a withdrawal element, so that a hole is left in the ground; leaving the base plate behind in the hole that is left; and introducing a setting substance on top of the base plate in the hole that is left. After the substance has set, a foundation pile is obtained in the ground.
