Method for producing a foundation element in the ground and foundation element

Abstract

The invention relates to a method for producing a foundation element in the ground, in which a hole is produced in the ground and a hardenable mass is introduced into the hole, which hardens to form the foundation element. According to the invention provision is made in that an insert body is inserted approximately centrally into the hole, the insert body being spaced apart from a circumferential wall of the hole, wherein a ring-shaped intermediate space is formed between the circumferential wall of the hole and the insert body, and in that a hardenable mass is introduced into the ring-shaped intermediate space, which hardens to form a ring-shaped foundation element.

1 .- 13 . (canceled) 
     
     
         14 . The method for producing a foundation element in the ground, in which
 a hole is produced in the ground and   a hardenable mass is introduced into the hole, which hardens to the foundation element,   wherein an insert body is inserted approximately centrally into the hole, the insert body being spaced apart from a circumferential wall of the hole, wherein a ring-shaped intermediate space is formed between the circumferential wall of the hole and the insert body, and   wherein the hardenable mass is introduced into the ring-shaped intermediate space, which hardens to form a ring-shaped foundation element,   wherein   the insert body is surrounded on its outer side by a sheathing element and   after hardening of the mass to the ring-shaped foundation element the insert body is withdrawn from the foundation element, wherein the sheathing element remains on the ring-shaped foundation element.   
     
     
         15 . A method according to  claim 14 ,
 wherein   the insert body is of tubular design.   
     
     
         16 . A method according to  claim 14 ,
 wherein   prior to the hardening of the mass one or several reinforcement elements are inserted into the ring-shaped intermediate space.   
     
     
         17 . A method according to  claim 14 ,
 wherein   the ring-shaped foundation element is designed to absorb a desired foundation load.   
     
     
         18 . A method according to  claim 14 ,
 wherein   the insert body is constructed of ring-shaped segments.   
     
     
         19 . A method according to  claim 14 ,
 wherein   a central cavity is surrounded by the ring-shaped foundation element.   
     
     
         20 . A method according to  claim 19 ,
 wherein   during the production of the hole ground material is removed and conveyed as excavated material out of the hole and   at least a part of the excavated material is returned into the central cavity of the ring-shaped foundation element.   
     
     
         21 . A method according to  claim 14 ,
 wherein   the hole is produced through drilling with a circular cross-section or through cutting with an angular cross-section.   
     
     
         22 . A method according to  claim 20 ,
 wherein   the ground material is mixed with a concrete mass.   
     
     
         23 . The foundation element produced pursuant to a method according to  claim 14 ,
 wherein the foundation element is produced in a ring-shaped manner from a hardenable mass in the ground,   wherein   the sheathing element remains on the ring-shaped foundation element.   
     
     
         24 . A foundation element according to  claim 23 ,
 wherein   a central cavity is designed in the ring-shaped foundation element.   
     
     
         25 . A foundation element according to  claim 24 ,
 wherein   the central cavity in the ring-shaped foundation element is filled with a non-hardenable material, in particular removed ground material.
