Definitions

  • the invention relates to a jacking pipe for the production of a substantially horizontally extending pipe whose wall consists of polymer concrete.
  • Such jacking pipes are used for example for the production of sewers, with a significant advantage is that the lines can be laid without the need to dug a trench.
  • the propulsion technique uses the pipeline as a means of transmitting the forces required for propulsion. This allows a significantly more cost-effective production of the line, although the design of the jacking pipes must take into account the propulsive forces to be transmitted. Due to the use of polymer concrete pipes, the finished pipe in operation also satisfies all practical requirements in terms of resistance to aggressive liquids and thus the service life.
  • the post-published EP 1 002 906 A1 describes a well pipe with the same longitudinally within its wall extending and spaced over the circumference of the tube spaced rods, wherein the well pipe may consist of polymer concrete and designed as glass fiber rods rods transmit the axial tensile loads.
  • the DE 72 06 442 describes a self-supporting tube well filter with a granular filter casing, which is assembled without the use of support elements only by plastic adhesive and plastic contact strengthening.
  • the DE 36 16 445 C1 describes a corrosion resistant pipe made of polymer concrete, wherein embedded in the tubular body in the longitudinal and annular direction continuous reinforcing elements such as rods, wires or bands are embedded.
  • the tube should have the smallest possible wall thickness and at the same time be biased to produce a compressive bias.
  • the invention has for its object to design a propulsion tube of the type described in the introduction so that it can also be used as a filter tube or drainage tube, z. B. for receiving leachate, is usable.
  • the wall of the jacking pipe is provided with at least one opening, which is filled in each case with a liquid-permeable filter material, which filter material is formed by binder-bound gravel-like grains.
  • a Polymer concrete thus consist of a liquid-permeable filter material which is formed by bound with binder, in particular with polymer, gravel-like grains.
  • the wall of the polymer concrete pipe may be provided with a plurality of openings, which are each filled with the liquid-permeable filter material.
  • These openings may be holes, but also, for example, strip-shaped, extending in the longitudinal direction of the tube openings, which are each filled with appropriately strip-shaped trained filter material.
  • the jacking pipe may consist predominantly or completely of polymer concrete.
  • the polymer concrete portion of the pipe may be a continuous structure that substantially determines the shape of the pipe.
  • the structure may be for this purpose e.g. be net or substantially barrel-shaped, without being limited thereto.
  • the area of the pipe made of polymer concrete can form the force-absorbing structure of the pipe.
  • propulsion tube 10 is provided with round holes 12, which are each closed by a plug 14 made of filter gravel.
  • This plug 14 can as
  • Kiesklebefilter be formed and consist of filter kies and, for example, polyester or vinyl ester resin. These resins can also be used as binders for the polymer concrete. This also applies to the following embodiments.
  • the filter plugs 14 have a pore volume which has the desired permeability to the liquid to be taken up by the tube 10.
  • the compressive strength of the plugs 14 is significantly less than that of the polymer concrete of the surrounding wall.
  • this is not disadvantageous because the wall 16 as a whole is dimensioned so that it is able to absorb the load which is effective at maximum propelling force.
  • the jacking pipe according to the Fig. 1 and 2 with an inner diameter of 400 mm and an outer diameter of 550 mm, ie a wall thickness of 75 mm be provided with holes whose largest diameter is 2.54 cm.
  • holes are arranged along the longitudinal extent of the tube at intervals of, for example, 10.0 cm, wherein the individual rows in the circumferential direction also a distance of 10.0 cm.
  • the arrangement is made such that the holes of two adjacent rows of holes are offset from each other, as this Fig. 1 shows.
  • the front ends 18 of the jacking pipe 16 are formed in the usual way for jacking pipes. This also applies to the connecting elements for connecting two adjacent tubes and seals located between the two tubes, etc.
  • the embodiments and elements can be provided or used, which are common and known for connecting jacking pipes for producing a pipe string. This also applies to the other embodiments, which are described below.
  • Fig. 3 is essentially consistent with that of Fig. 1 and 2 match, so that the same or corresponding parts are also provided with the same reference numerals, in Fig. 3 are each 100 higher.
  • the openings 112 of the tube 110 of the Fig. 3 are formed as extending in the longitudinal direction of the tube 110 strips which are closed by correspondingly shaped strip-shaped body 114 made of filter material.
  • the drawing shows that the openings 112 are narrower inwardly from the outer surface, so that consequently the filter body 114 have approximately the shape of a blunt wedge.
  • the apertures in the tube wall closing filter body can be preformed and z. B. be attached using an adhesive to the pipe wall.
  • Fig. 4 are parts that comply with those of the embodiment according to Fig. 1 match or correspond to the same, but provided by 200 higher reference numerals.
  • the arrangement is such that the recess 212 occupies a contiguous larger surface, which extends for example over two-thirds of the length of the tube 210 and over about 180 ° of the circumference of the tube 210. Accordingly, this also forms the recess 212 filling Filter material a contiguous body 214, which forms a substantial part of the shell of the tube 210.
  • An advantage of this embodiment may be that when installing the tube 210 in the in Fig.
  • the lower portion of the inner tube cross-section forms a channel for the outflowing liquid, which is not interrupted by filter areas through which, if necessary, liquid could escape from the tube 210.
  • the teaching according to the invention is applicable in many ways, since it has been found that the use of perforated pipes as jacking pipes, the holes are filled through plugs of filter material, and / or of pipes with differently shaped, possibly also large openings are provided, which are filled with filter material, in any case is possible if the dimensioning of the tubes and / or the arrangement of the apertures take into account the need for the transmission of the feed forces.
  • the jacking pipes according to the invention are suitable for example for the production of seepage pipes in landfills, but also for the production of essentially horizontally arranged filter wells.
