<p>#CMT# #/CMT# The foundation pile involves a compact machine with an open drill motor (5). Hollow cylindrical steel pipes or pipe segments (1) to which an end part (2) is welded are used, with or without a weighted foot with a point and screwlines (3). A pipe segment (4) with the aid of the hydraulic rotary motor (5) and the pull-down (6) is inserted into the ground. #CMT# : #/CMT# During the rotation of the pipe or pipe segments (1,4), a hydraulic clamp (10) is set in action and the machine via plunger arms (7,8) is anchored to the concrete floor in order to guarantee the rotating torque. During the rotation, concrete/grout is applied (9), ensuring that the shaft formed in the ground accommodates the diameter of the pipe or of the weighted foot with point and screw lines. #CMT#USE : #/CMT# For the insertion of a foundation pile into the ground. #CMT#ADVANTAGE : #/CMT# The invention fulfils the requirement in areas where space is limited for ground drillling to be effected with a compact machine, so that the risk of damage to foundations and adjacent areas does not occur. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure displays a phase of the process of the installation of a foundation pile in the ground. 1 : pipe or pipe segments 2 : pipe or segment end part 3 : point or screwlines 4 : pipe segment 5 : hydraulic rotary motor 6 : pull-down 7,8 : plunger arms 9 : concrete/grout 10 : hydraulic clamp.</p> |
