  • the plates 27 and the rod sections 21a, 22a and 21b, 22b are preferably made of steel so that they can be connected by welding.

  • the rod sections 21a, 21b and 22a, 22b have a length in the direction of advance y which is slightly greater than the length of the tubular elements 18 used in the individual case. The function thus enabled results from the procedure described below for driving the tubular elements 18.

So that there is a stable and pressure-resistant arrangement, d. H. the push rods 21, 22 do not bend upwards or downwards when subjected to pressure, the guide and transport tube 10 on its outer jacket is expediently provided with pairs of guide and positioning means, e.g. B. attached by welding, L-shaped guide rails 28 which form between them guide gaps 29 which substantially correspond to the width of the push rods 21, 22 (Fig. 3).

This is explained in more detail below on the basis of the various method steps which are to be carried out when using the device according to the invention.
  • Sections of the conveyor device 5 and the tube 10, in the course of the continuously lengthening through-hole 3, are coupled to one another by means of the coupling elements 12 (FIG. 1) further sections of the conveyor device 5.
  • a single pipe element 18 is first pushed after the working pipe 6.
  • the jacking unit 14 can be used to act directly on the rear end of the tubular element 18 in the jacking direction y, the front end of which would lie against the rear end of the working tube 6 and would also drive it forward.
  • the first tubular element 18a shown on the left in FIG. 2, would then be inserted into the through-hole 3 such that the push rods 21, 22 or rod elements 21a, 22a assume the position shown in FIGS. 1 to 3.
  • the tubular element 18a is then z. B. as usual with the help of the propulsion unit 14 from the starting trench 2 until it is also entirely or predominantly arranged in the through hole 3.
  • the working tube 6 can be driven forward in that the propulsion unit 14 also acts on the rear ends of the rod elements 21a, 22a. This first phase of tunneling is not particularly critical.
  • the tube element 18a on the left in FIG. 2 is the first tube element pushed after the dismantling unit 1
  • a further portion is first coupled to the portion of the conveyor device 5 already located in the through bore 3.
  • the rod sections 21b, 22b are coupled to the rod sections 21a, 22a in the manner shown in FIGS. 2 and 4 and are axially fixedly connected to them by transverse pins inserted into the transverse holes 26.
  • the driver elements 23 come to rest on the front ends of the rod sections 21b, 22b and behind the rear end of the pipe section 18a which has already been inserted into the through-hole 3.
  • next tubular element, here 18b, is then pushed onto the preassembled rod sections 21b, 22b until its front side abuts the driver elements 23.
  • a force directed in the direction of advance y is now exerted on the rod sections 21b, 22b and the tubular element 18b with the aid of the propulsion device 14.
  • the driver elements 23 of the rod sections 21b, 22b therefore bear against the rear end of the tubular element 18a already in the through-hole 3, as a result of which this is coupled to the substructure 20 in the direction of propulsion and is then advanced solely by the latter.
  • tubular elements 18 can be used which are substantially less stable than the previously used tubular elements, as is the case, for example, for conventional concrete or stoneware pipes.
  • the excavation unit 1 and the conveying device 5 together with the guide and transport pipe 10 are first recovered from a target trench arranged at the other end. This releases the rod sections 21a, 21b and 22a, 22b, respectively, so that they can be pivoted inwards and then pulled out of the pipeline, the cross pins being pulled out of the associated cross holes 26 one after the other. If the driver elements 23, as shown in particular in FIG. 3, are arranged on the two sides of the guide and transport tube 10, the rod sections 21a, 21b, 22a, 22b etc. fall out automatically when the tube 10 is pulled out, even under the influence of gravity the bottom of the pipeline so that it only needs to be pulled out towards the target trench.
  • a still safe falling out of the driver elements 23 can be achieved in that the push rods 21, 22 in Fig. 3 are arranged slightly V-shaped to each other. Alternatively, however, it would also be possible to recover the conveyor sections as usual from the starting trench 2, since there is usually more space here. In this case, the rod sections 21a, 21b, 22a, 22b are also expediently pulled out of the tubular elements 18 toward the starting trench 2.
  • the thicknesses and the positions of the driving elements 23 are selected such that the clear distances between two driving elements 23 one behind the other in the driving direction are then if the substructure 20 is in the fully assembled state, ie the rod elements 21a, 21b or 22a, 22b are arranged in abutment, are somewhat larger than the distance between the end faces of the tubular elements 18. This ensures that while the driving elements 23 abut the rear ends of the tubular elements 18 leading them, the front ends of the tubular elements 18 come to lie with sufficient play in front of the driving elements 23 leading them and do not touch them. As clearly shown in FIG. 2, sufficiently wide butt joints or gaps 30 remain between the individual tube elements 18, which enables the driver elements 23 to be easily removed.
  • the pipe elements 18 are preferably provided at their rear ends with sleeves 31 which accommodate the front ends 32 of the subsequent pipe elements 18, which may be somewhat reduced in cross-section, and also sufficient space for an annular sealing element 33 to let.
  • the arrangement according to FIG. 2 is such that the pipe ends do not abut against one another during propulsion and the rear ends of the pipe elements 18 are protruded by the sleeves 31 with a sufficient axial length.
  • the invention is not restricted to the exemplary embodiment described, which can be modified in many ways. This applies primarily to the dismantling unit used in the individual case, which is designed differently than shown and instead of the screw conveyor some other conveyor, e.g. B. could have a hydraulic or provided with reciprocating lorries for the mined soil. It is clear that the conveyor 5 can be supported, if necessary, with suitable means on the bottoms of the tubular elements 18 so that it is automatically advanced with the tubular elements 18. Such means are e.g. For example, support feet 34 shown schematically in FIG. 3.
  • Subconstructions other than those shown can also be provided, in particular those which, instead of the push rods, surround the tube 10 closing Rohräb sections, lattice girders or other constructions and are statically sufficiently stable.
  • Other driver elements can also be provided, e.g. B. those that are driven out with the help of spring elements from the butt joints between the pipe elements as soon as the guide and transport pipe 10 is pulled out of the pipeline. It would also be possible to arrange the driver elements at the rear ends of the rod sections and in such a way that they do not hinder the insertion of the tubular elements, or to provide the driver elements in middle regions instead of at the ends of the rod sections, in which case the rod sections are in some cases assigned to two successive pipe elements would.
  • the driver elements by extrusion welding or the like to the inner sheaths of the tubular elements instead of to the rod elements, in particular if the tubular elements are made of plastic (e.g. PVC) or the like and have no sleeves and therefore have to be butt welded together.
  • the tubular elements not individually, but z. B. in pairs or in piles of three or more tubular elements to the substructure, in which case the tubular elements would have to be sufficiently stable to correspondingly push two or more tubular elements in front of them. If each of these groups is limited to just a few pipe elements, the forces to be transmitted by each individual pipe element are comparatively small in this case too.

Abstract

L'invention concerne un procédé et un dispositif permettant de réaliser une canalisation souterraine, en particulier dans les travaux publics. A partir d'une tranchée de départ (2), un forage souterrain (3) est réalisé, plusieurs éléments tubulaires (18) formant la canalisation étant poussés dans ledit forage. La poussée des éléments tubulaires (18) est réalisée par le fait que l'on fait avancer une infrastructure (20) s'étendant à travers les éléments tubulaires (18), ces derniers étant accouplés avec l'infrastructure (20), dans le sens d'avancement, individuellement ou de façon groupée.
