Definitions

  • the invention relates to a foundation system for the excavating in the ground of a pit to be filled with a hardenable mass for the forming after hardening of a foundation pile.
  • a foundation system in which a bucket with a scoop base is screwed into the base, which bucket is then filled with soil, after which the bucket is raised out of the ground in order to discharge the soil. This process is repeated until a desired depth has been reached.
  • the pit is filled during excavation with a bentonite-containing suspension which serves as a support liquid.
  • the bucket should be moved once downwards and upwards through the support liquid. A pit is thus gradually excavated in the ground.
  • the pit is subsequently filled with concrete which in this case expels the support liquid, so after hardening a concrete foundation pile is formed.
  • a drawback of the prior-art system is that this gradual excavation and subsequent forming of a foundation pile is a time-consuming process, soil being excavated effectively for less than 10 percent of the required time.
  • a further drawback is that the excavated soil can become contaminated with the support liquid.
  • EP 00160736 discloses a foundation system in which a bucket is provided at the lower end of a telescopically extendable tube assembly for the excavating of soil.
  • a drawback of this prior art method is that relatively high forces are necessary to excavate the pit, especially if foundation piles having large cross sections or lengths have to be formed.
  • there is a risk of premature collapsing of the excavated pit whereas temporary filling of the previously excavated pit portion with a support liquid will lead to marked contamination of the excavated soil with the support liquid.
  • the object of the present invention is to overcome at least some of the above-mentioned drawbacks or else to provide a usable alternative.
  • the object of the invention is to provide an environmentally-friendly foundation system allowing in a broad range of soil types reliable, rapid and efficient excavation of a pit which can subsequently be filled with a hardenable mass for the forming of a foundation pile.
  • the system comprises in this case a rod-like drive-in member having a drill head connected to the underside thereof.
  • the drill head comprises a housing having a drive shaft which is rotatable with respect to this housing.
  • a drive unit for the driving in rotation via the drive shaft of the at least one digging member is provided in the housing.
  • the drive unit is provided with energy by means of a power supply extending from an energy source above ground to the drive unit in the housing of the drill head.
  • Also provided is an installation for the lowering into the ground, during driving of the digging member, of the drive-in member together with the drill head.
  • a pit can thus be formed in the ground in a continuous excavating process, while the forces required to do this are relatively low.
  • the rod-like drive-in member and a large portion of the drill head do not have to be driven in rotation.
  • WO 03/085208 has previously disclosed a system for the forming of a foundation element in the ground, using a drill head provided with its own drive unit.
  • the drive unit is located within a housing and is powered from an energy source located above ground.
  • the drill head is in this case not connected to the lower end of a rod-like drive-in member and is not lowered into the ground by a drive-in member.
  • the drill head itself digs down into the ground.
  • tube segments are pressed into the ground with the aid of a press installation in the pit excavated by the drill head.
  • these tube segments are not intended to drive the drill head forward into the ground but rather are, if necessary, drawn into the ground along with the drill head.
  • these tube segments are intended to be left behind in the ground where they form the pit wall of the foundation element. Once the desired depth has been reached, the drill head is then removed, through the tube segments which are left behind, up out of the pit thus formed, for which purpose the drill head is configured with smaller radial dimensions than the tube segments.
  • the drill head comprises a flushing chamber which is positioned above the digging member in the housing and has a supply and discharge extending from the drill head to a position above ground.
  • the supply is used in this case for the pressurized introduction during drilling of a flushing liquid into the flushing chamber.
  • the discharge is used to discharge during drilling the supplied flushing liquid mixed with soil removed by the digging member out of the flushing chamber. Soil which is removed by the digging member passes directly into the flushing chamber. The removed soil is in this case pressed continuously into the flushing chamber by the digging member and the drill head which advances downwards together with the rod- like drive-in member. The soil which is released can mix in the flushing chamber with the flushing liquid and easily be discharged via the discharge.
  • the pressure of the flushing liquid supplied in the flushing chamber is preferably set to an excess pressure slightly higher than the prevailing groundwater pressure in the surrounding soil.
  • the excess pressure is in this case approx. 0.1 - 0.3 bar. This excess pressure ensures that the soil at the site of the digging member can be discharged in a controlled manner. This reduces the risk of undesirable disturbances in the surrounding soil and thus the risk of scouring and subsidence.
  • the use of the flushing chamber at a slight excess pressure allows the discharge rate of the soil mixture to be precisely adapted to the desired drilling speed.
  • the underside of the flushing chamber is delimited in the housing by a base plate provided with inlets. This increases the efficiency with which the flushing liquid mixes with the removed soil particles.
  • the invention also relates to a method according to claims 26 - 28, to an assembly consisting of a drive-in member and a drilling head according to claim 29 and also to a foundation pile according to claim 30.

  • Figure 2 is a schematic view in cross section of a variation of the drilling head in Figure 1;
  • Figures 3a, b, c and d show successive steps of a method according to the invention using a foundation system according to Figure 2;
  • Figure 4 is a view corresponding to Figure 2 containing different types of drilling members.
