    • A method for driving a pile (1) into the ground to a position below the ground level by means of a lengthening piece (2) which is pulled out of the ground after the pile has been driven to the desired depth. The pile is provided with at least one pipe which is open at its ends, said pipe extending at least substantially along the length of the pile and being fixed to said pile. A lower end of a flexible pipe (11) accommodated within the extension piece is connected to the upper end of the pipe that is fixed to the pile, and an upper end of the flexible pipe that freely extends within the lengthening piece is connected to a grout pump via a lead-through extending through the wall of the lengthening piece. Grout is forced into the ground through the open lower end of the pipe (4), via the flexible pipe (11) and the pipe (14) fixed to the pile, by means of the grout pump during the pile-driving operation. Once the pile has been inserted, the lengthening piece is pulled out of the ground.
    • 一种用于通过在桩被驱动到所需深度之后被拉出地面的延长件(2)将桩(1)驱动到地面中到地平面下方的位置的方法。 该桩设置有至少一个在其端部开口的管道,所述管道至少基本上沿着桩的长度延伸并固定到所述桩上。 容纳在延伸片内的柔性管(11)的下端连接到固定到桩的管的上端,并且在延长件内自由延伸的柔性管的上端连接到 通过延伸穿过延长件的壁的引导件进行灌浆泵。 在打桩操作期间,灌浆通过柔性管(11)和固定到堆的管(14)通过管(4)的敞开的下端被迫进入地面。 一旦插入桩,将延长件从地面拉出。
