Method and device to create a foundation as well as a foundation

Abstract

A method and a device to create a foundation in which a foundation pipe is driven into the soil. At least one bore is created into the soil in the perimeter area of the foundation pipe to insert before ramming by means of a drilling tool the diameter of which is significantly smaller than a diameter of the foundation pile. The soil material removed during drilling remains essentially within the bore. Furthermore, a foundation with a foundation pipe which is created accordingly.

         16 . Method to create a foundation in which a foundation pipe is driven into a soil,
 wherein   that before the driving-in by means of a drilling tool the diameter of which is significantly smaller than a diameter of the foundation pipe at least one bore is created into the soil in the perimeter area of the foundation pipe to insert, and that the soil material removed during drilling remains essentially in the bore.   
     
     
         17 . Method according to  claim 16 ,
 wherein   that several bores are created which are arranged circularly in the soil along the perimeter area of the foundation pipe to insert.   
     
     
         18 . Method according to  claim 17 ,
 wherein   that the bores are arranged in a touching or overlapping manner.   
     
     
         19 . Method according to  claim 17 ,
 wherein   that adjacent bores are created with a distance to each other whereby a soil segment remains between the adjacent bores.   
     
     
         20 . Method according to  claim 16 ,
 wherein   that the at least one bore is deepened up to a drill depth which is less than or is the same as the ramming depth of the foundation pipe.   
     
     
         21 . Method according to  claim 16 ,
 wherein   that the foundation pipe is driven into the soil by means of a ramming device which is designed either as percussive drive hammer or an oscillating vibrator.   
     
     
         22 . Method according to  claim 16 ,
 wherein   that the foundation pipe is driven into the soil of a body of water to create an underwater foundation.   
     
     
         23 . Method according to  claim 22 ,
 wherein   that the drilling tool is driven rotationally by a drilling device which can be moved on the working platform along the perimeter of the foundation pipe to insert.   
     
     
         24 . Method according  claim 23 ,
 wherein   that the work platform floats on the surface of the body of water or is lowered to the ground of the body of water.   
     
     
         25 . Method according to  claim 23 ,
 wherein   that at the work platform is provided at least one circular drill guide which has guidance devices for the drilling tool according to the positions of the bores to insert.   
     
     
         26 . Method according to  claim 16 ,
 wherein   that during the drawing back of the drilling tool from the soil fill material, in particular a hardenable material, is fed to the bore.   
     
     
         27 . Foundation with a foundation pipe which is driven into a soil, in particularly according to a method according to  claim 16 ,
 wherein   that at least one bore is inserted into the soil in the perimeter area of the foundation pipe before the driving-in, the bore diameter of which is significantly smaller than a diameter of the foundation pipe and   that the at least one bore is filled with soil material which accumulates during creating the bore.   
     
     
         28 . Device to create a foundation with a foundation pipe into the soil, in particularly to carry out a method according to  claim 16  with a working platform including a ramming device to drive the foundation pipe into the soil,
 wherein 
 that on the work platform is provided a drilling device with drilling tool, the drill diameter of which is significantly smaller than a diameter of the foundation pipe to install, and 
 that the drilling device can be moved along a perimeter area of the foundation pipe to drive in. 
 
     
     
         29 . Device according to  claim 28 ,
 wherein   that the working platform to create an underwater foundation is designed floatable and/or lowerable.   
     
     
         30 . Device according to  claim 28 ,
 wherein
 that the drill device has a pipe-shaped drilling tool via which pipe interior fill material can be introduced into the bore.
