Definitions

  • the invention relates to a method for searching under foundations in the form of floor panels, single or strip foundations.
  • the starting point of such processes are subsidence phenomena on already completed structures, which must be compensated.
  • the invention further relates to a drilling and mixing tool in conjunction with a rotationally drivable drill string, wherein the drilling and mixing tool comprises a coaxial with the drill string aligned central part and at least two individually on the central part beiklappbar movably arranged folding cutters.
  • a method for undertaking a groundwater standing structure in which a borehole is sunk into the ground beneath the structure by breaking through the structure floor and a soil composite column of suspension and soil, the diameter of which is larger, is produced by means of a tillage device in the manner of an injection nozzle carrier. than that of the borehole.
  • the diameter of the harrow remains unchanged.
  • a method of making concrete piles in the ground which first drills a wellbore of lesser diameter than the pile diameter and drills the wellbore to a larger diameter in the backward direction prior to extruding concrete from the bottom of the wellbore.
  • a corresponding drilling tool comprises an inner drill string and an outer drill string with radially aus tone Schneidkörpem having at the back to the hole opening towards cutting members.
  • An expandable separating screen serves to separate a rinsing zone, from which the cuttings are carried away, from an injection zone, which is filled with concrete.
  • the present invention has for its object to provide a method for securing the foundation of the type mentioned.
  • the above-mentioned method steps are subsequently performed with a drilling and mixing tool fastened to a drill pipe without intermediate pulling of the drill pipe.
  • the drilling and mixing tool used is increased in diameter, with a binder is fed and mortared with the ground.
  • This causes a subsequent foundation of the foundation, which can serve to increase the carrying capacity or the settlement of settlement phenomena.
  • the process can be distributed on individual foundations distributed according to a grid.
  • the said at least one larger diameter in the area of Bodenvermörtelung can be adjusted as needed. It can also be varied by the height of the mortar column.
  • the deep Bodenvermörtelung can already be started the first drilling of the drilling and mixing tool and if necessary continue with its pulling or only when pulling the drilling and mixing tool after the drilling to the lowest point to be started.
  • the present invention has for its object to provide a drilling and mixing tool that can be used in the aforementioned method.
  • the solution to this consists in a drilling and mixing tool in conjunction with a rotating drivable drill pipe, wherein the drilling and mixing tool comprises a coaxial with the drill string aligned central part and at least two individually arranged on the central part hinged cutters which are beiklappbar to the central part and on different diameters are hinged and fixable, and wherein outlet nozzles are provided on the drilling and mixing tool, which are supplied via the drill pipe with liquid medium, wherein folding blades are each firmly connected to steering levers, which lie in two different levels and can cross, and on the steering lever acting on the steering arms, which are connected via a first pivot point with the lower end of an actuating rod and via second pivot points with the steering levers.
  • the setting up Different diameters can be constructively designed as a continuous adjustment or as adjustment in individual stages.
  • liquid medium water can be used during the drilling process with the folding flaps folded in, while after unfolding the folding cutters to the desired diameter, it is possible instead to supply binders in order to bring about soil softening.
  • the folding cutters are formed so that they comprise transverse to the longitudinal axis of the drill string pivot axes. This allows for an improved storage and support, on the other hand higher specific cutting forces on the folding blades for a given torque of the drill string.

  • the two folding trimmers are each fixedly connected to and actuatable by steering levers, these steering levers lying in two different planes and moving in them, so that they can cross each other in side view.
  • An actuating rod for the folding cutters or the steering levers can be arranged longitudinally movable in the drill string.
  • handlebar arms act, which are connected on the one hand with the operating rod and on the other hand with the steering levers articulated.
  • the folding cutters can each form an angle of attack to radial or conical planes of rotation, in the sense that they cause a screwing into the ground when sinking in the unfolded state.
  • the angle of attack can amount to about 30 ° with respect to a radial plane to the longitudinal axis of the drill string in a right angle unfolded state.
  • the folding cutters have in particular large width in the the folding blades disturbed floor areas. For the rest, this does not hinder the escape of liquid medium when folded folding cutters.
  • the outlet nozzle for liquid medium can be arranged above the articulation of the folding cutters and / or below the articulation of the folding cutters. This makes it possible that, depending on the process control and direction of movement of the mixing tool, the outlet of drilling fluid follows the folding blades and / or the outlet of binder suspension leads the folding blades.
