Definitions

  • the invention relates to a method for anchoring a pipe feed device, which is used in particular in the trenchless laying of pipelines.
  • a tubing string of jacking pipes is trenchlessly led to a target side, with the tubing string being progressively extended by adding a respective rearmost jacking pipe.
  • a pipe feed device pipe thruster
  • arranged in the starting pit engages on the respectively rearmost driving pipe and presses the pipe string in the direction of the target side.
  • a tunneling machine e.g. having a drill head.
  • a product pipe string can be pushed by means of the pipe feed apparatus.
  • the tube feeder is designed to exert tensile forces as well, and is used to retract a tubing string, e.g. to retract the jacking pipe string into the starting pit after coupling a product pipe string thereto at the target side.
  • the pipe feed device engages, for example via a collar on the side of a pipe to be pushed or pulled, the cuff can be moved back and forth by means of hydraulic cylinders.
  • Typical forces exerted by the tube feeder are on the order of 5 MN or 7.5 MN. These forces must be dissipated via a base into the ground. This requires a stable anchoring.
  • the inventive method for anchoring a pipe feed device in particular in the trenchless installation of pipelines, is suitable when the application area of the pipe feed device is surrounded in the field by an arrangement of vertical stabilizers from which steel support sections project.
  • Such vertical stabilizations eg in the area of excavations, are common. For example, they can be prepared by placing them in a hole made with a snail-like drill a steel beam is rammed. The borehole can additionally be stabilized eg with concrete.
  • the steel beams eg double T-beams
  • the steel beams are not completely rammed into the ground, but it projects in each case a steel beam portion above the ground.
  • further vertical stabilizations can be arranged between reinforced by steel beams vertical stabilizations that do not contain steel beams and in which, for example, only concrete is introduced into the drill hole.
  • the uprising steel beam sections define a boundary line that defines the area in which the base of the pipe feeder is located, thus defining a surface.
  • a steel structure is used in this surface, which is secured by the steel beam sections against lateral deflection, in particular against dodging under the counter forces occurring during operation of the pipe feed device.
  • the base of the pipe feeder is attached to the steel structure.
  • the use of a steel construction for anchoring the pipe feeder has several advantages over a concrete slab.
  • the steel structure is in principle reusable and ready for use after a short time. It does not have to wait until a concrete slab has hardened. Securing the steel structure on towering steel girder sections, which are present anyway, is very stable. Therefore, additional safeguards may be eliminated, such as the oblique introduction of piles, which is expensive. After completion of the work, the steel structure can be quickly removed, in contrast to a heavy concrete slab.
  • the steel construction preferably has a substantially rectangular base. Other geometric shapes are coming However, also considered, in particular, if the surface defined by the boundary line of the steel beam sections is not rectangular.
  • a steel structure having a substantially rectangular base is preferably reinforced on its narrow sides, i. on the sides at which the forces act during operation of the pipe feed device. If the pipe feeder is designed only for exerting compressive forces or only compressive forces are exerted on a given site, the reinforcement of the steel structure can be provided only on the claimed narrow side.
  • the vertical stabilizers can only be introduced into the subsoil with limited accuracy and therefore the boundary line defined by the steel girder sections shows typical deviations of approximately 10 cm from its nominal course, it is advantageous to plan the size of the steel structure so that after the steel construction has begun Gaps between the towering steel girder sections and the steel structure remain.
  • These gaps are preferably keyed (e.g., with steel wedges) and / or welded. If necessary, additional parts may also be used, e.g. Remnants of steel beams to reduce gaps before welding or before inserting steel wedges.
  • the steel structure has a plate construction.
  • the plate construction may, for example, contain juxtaposed double T-beams which are welded together at their flanges. Such a construction can be made from readily available starting material and is very stable.
  • the steel structure comprises a plurality of individual parts which are connected to each other before using the steel structure.
  • the individual parts may already be prepared for connection with one another, e.g. by a tab welded to one of the individual parts, which is welded or screwed to a counterpart.
  • the attachment may e.g. done with vertically aligned bolts. If these are present in sufficient numbers and sufficiently dimensioned, they can easily transfer the forces occurring from the base to the steel structure. It is also conceivable to apply the base of the pipe feed device to a reinforcement of the steel construction, so that the forces occurring during operation of the pipe feed device act on the steel construction via this reinforcement.
  • FIG. 1 is an embodiment of a pipe feed device 1 is shown in three-dimensional view.
  • the pipe feed device 1 has a base 2 with a total of four feet 3.
  • two hydraulic cylinders 4 are mounted, which can be retracted and extended in the embodiment not only can exert pressure forces for advancing pipes, but also tensile forces for pulling on a pipe.
  • the free ends of the hydraulic cylinders 4 carry a sleeve device 6, into which a pipe or an end of a pipeline can be inserted, so that the sleeve device acts on the lateral surface of the pipe or the pipe.
  • the sleeve device 6 is guided on a track 8.
  • the inclination angle of the track 8 can be adjusted to adapt the pipe feed device 1 to the conditions of a construction site.
  • FIG. 2 an open excavation 10 a construction site is shown in plan view.
  • the pipe feed device 1 is mounted in the excavation 10 to advance from there a pipeline, which is composed for example of feed pipes, in a pipe jacking process in the ground.
  • the area of use of the pipe feed device 1, i. the area where its base 2 is located and anchored is surrounded by an array of vertical stabilizers 14.
  • These are preferably deep-soil stabilizers according to DIN 14679, which are e.g. can be created with a screw auger and by filling concrete and overlap each other in the embodiment.
  • a steel beam 15 double T-beam
  • the upper portion of a steel beam 15 projects in each case as a steel support section 16 on the ground.
  • the steel beam sections 16 define with their inner flange in the view according to FIG. 2 a boundary line, by which a rectangular area in the embodiment is defined.
  • the vertical stabilizers 14 of the excavation 10 are comprised of an array of outer vertical stabilizers 18 which also surround the area of action of the sleeve means 6 of the tube feeder device 1. There, where the pipeline is introduced into the soil, there is a border 19 of other vertical stabilizers.
  • a steel structure 20 is inserted in the surface defined by the above-defined boundary line defined by the steel beam sections 16.
  • An embodiment of the steel structure 20 is based on FIGS. 4, 5 and 6 explained.
  • FIG. 4 shows the steel structure 20 in plan view. It can be seen that the steel structure 20 is dimensioned so that it can still be used in said surface, but there are only small gaps to the towering steel beam sections 16. These gaps can be against the steel beam sections 16 wedged (preferably with steel wedges) and / or welded, it is advantageous for larger gaps that may occur due to unavoidable tolerances in the arrangement of the steel beams 15, still introduce additional material (eg steel support pieces) in the gaps.
  • additional material eg steel support pieces
  • the steel structure 20 has a plate construction 22 containing juxtaposed double T-beams 24 welded together at their flanges, see FIG. 6 .
  • reinforcements in the form of double T-beams are welded to the top of the plate construction, see FIG. 4 and FIG. 5 .
  • the reinforcements 26 effect better transmission of force to the steel beam sections 16 on the particularly stressed sides of the steel structure 20.
  • FIG. 4 are the feet 3 of the base 2 of the pipe feed device 1 located. In the exemplary embodiment, they practically abut against the reinforcements 26.
  • the feet 3 are each provided with four holes 28 are guided by the bolts for attachment to the plate structure 22.
  • the steel structure 20 makes it possible to anchor the pipe feed device 1 quickly and safely in the excavation 10.
