Definitions
- the invention relates to a method specified in the preamble of claim 1 Genus and a device according to the preamble of claim 4.
- the invention is based on the object, the method and the device of at the outset designated type in that the nachzuschiebenden the dismantling unit Pipe elements are exposed to significantly smaller loads and therefore much cheaper pipes can be used.
- the invention has the advantage that due to the drive coupling the tube elements to a arranged in its interior, gradually advanced Substructure each individual pipe element only to his own propulsion must absorb necessary forces.
- the main load is absorbed by the substructure, which comparatively inexpensively from push rods, pipes, lattice girders od. Like. Are assembled can and z. B. is made of steel.
- an apparatus for producing an underground pipe a removal unit 1, which is driven from a starting or Preßgrube 2 in a preselected, usually horizontal advancing direction v , so that a gradually longer, suitable for receiving the pipe through hole 3 arises.
- the dismantling unit 1 includes in the exemplary embodiment a cutting head 4, which can be rotated by means of a drive motor, not shown, in revolutions and has a substantially the inner diameter of the through hole 3 corresponding outer diameter. With the cutting head 4 a this in the direction of arrow v trailing and rotatable here with him conveyor 5 is connected in the form of a screw conveyor, which serves the purpose of transporting detached from the cutting head 4 soil in the start pit 2.
- the dismantling unit 1 usually has a working tube 6, at the front end of a control head 7 is pivotally mounted, which is adjustable by means of hydraulic or pneumatic cylinder / piston assemblies 8 within certain limits to correct the propulsion direction v as needed or influence to be able to.
- the control head 7 has a rearwardly tapered sliding surface 9, which creates a transition from the diameter of the through-hole 3 to the smaller inner diameter of a guide and transport tube 10 and forms a type of hopper for the mined material.
- the conveyor 5 is composed of individual sections, which are coupled in the direction of advance v or in the direction of a parallel axis 11 of the through hole 3 to each other, as indicated in Fig.
- the guide and transport tube 10 is composed of individual pipe sections, which are arranged in succession on impact.
- Fig. 1 schematically a hydraulic or pneumatic, acting on the guide and transport tube 10 and / or the conveyor 5 propulsion unit 14 indicated by means of which the cutting head 4, the conveyor 5 and the guide and transport tube 10 in the course of To be driven for a longer through hole 1.
- the actual pipeline is formed by means of tubular elements 18, which the Working tube 6 are pushed from the starting pit 2 and the outer diameter essentially correspond to the inner diameter of the perforation 3.
- the inner diameter of the Pipe elements 18 sufficiently larger than the outer diameter of the guide and Transport tube 10, so that between the two a hollow space 19 (Fig. 2 and 3) arises in the manner of a cylinder ring.
- the substructure 20 is formed by two push rods 21 and 22, preferably made of square tubes.
- Each push rod 21, 22 is, as shown in particular in FIGS. 2 and 4, composed of a plurality of rod sections 21a, 21b, or 22a, 22b arranged one behind the other in the direction of advance v .
- Each rod portion 21a, 22a and 21b, 22b is provided at one end as shown in FIG. 2 and 4 with a driver element 23 which projects radially outwardly from the respective rod member.
- the rod portions 21a, 22a and 21b, 22b have at their ends preferably axially cooperating plug connection elements, by means of which they are axially connectable to each other.
- the receiving openings 24 are formed using tubular rod portions 21a, 21b and 22a, 22b, respectively, by their hollow end portions, while the projections 25 suitably protrude from plates 27 fixed to the respective ends of the rod portions (here 21b, 22b) and with radial , Extensions projecting beyond the circumference of the rod sections 21b, 22b simultaneously form the driver elements 23.
- the plates 27 and the bar sections 21a, 22a and 21b, 22b are preferably made of steel so that they can be joined by welding. Alternatively, it would be possible to provide the plates 27 on both sides with projections 25 and transverse holes 26 and to connect in each case by transverse pins with the two abutting ends of the rod portions 21a, 21b and 22a, 22b.
- the rod sections 21a, 21b and 22a, 22b have a length in the direction of advance v which is slightly greater than the length of the tubular elements 18 used in the individual case.
- the function enabled thereby results from the procedure described below for the propulsion of the tubular elements 18.
- the substructure 20 each have two push rods 21, 22 and Rod sections 21a, 21b, 22a, 22b, the diametrically according to FIG. 1 to 3 on each other opposite sides of the guide and transport tube 10 are arranged.
- the rod sections expediently have a width which is approximately equal to the radial width of the Interspace 19 corresponds, so that they in the radial direction by the outer or Inner walls of the tube 10 and der Rohretti 18 out and against kinking are secured. This will be explained in more detail below with reference to the various method steps explained, which are to be executed when using the device according to the invention.
- tube elements 18 can be used, which is essential less stable than the previously used tube elements, e.g. for usual Concrete or vitrified clay pipes applies.
- a sure fall out of the Carrier elements 23 can be achieved in that the push rods 21, 22 in FIG. 3 slightly V-shaped to each other.
- the rod sections are useful 21a, 21b, 22a, 22b pulled out to the starting pit 2 out of the tubular elements 18.
- the driver elements 23 during the propulsion of the tubular elements 18 is not unintentional jam in the butt joints between two consecutive tubular elements 18, the thicknesses and the positions of the driver elements 23 are selected so that the clear Distances between two driving elements one behind the other in the direction of advance 23, when the substructure 20 in the assembled state located, d. H. the rod elements 21a, 21b or 22a, 22b are arranged in abutment, are slightly larger than the distance of the end-side end faces of the tubular elements 18th equivalent. This ensures that while driving the driver elements 23 at the rear ends of them run ahead pipe elements 18, the front ends the tubular elements 18 but with sufficient clearance in front of them ahead Driver elements 23 come to rest and do not touch them. As Fig. 2 clearly shows, remain between the individual tubular elements 18 sufficiently wide, the easy removal of the driver elements 23 enabling butt joints or column 30th
- Pipe elements 18 In order to lay the pipeline still liquid or gas tight, are the Pipe elements 18 preferably provided at their rear ends with sleeves 31, which in the Cross section optionally slightly reduced front end 32 of the subsequent tubular elements 18 in and also sufficient space for a ring-shaped Leave sealing element 33.
- the arrangement of FIG. 2 is such that the pipe ends when driving do not collide against each other and the rear ends of the pipe elements 18 are surmounted with sufficient axial length of the sleeves 31.
- the invention is not limited to the described embodiment, which can be modified in many ways. This applies primarily to those in individual cases used dismantling unit, which are designed differently than shown and instead of the screw conveyor any other conveyor, e.g. B. a hydraulic or with back and having driving loren provided conveyor for the excavated soil could. It is clear that the conveyor 5, if necessary, with appropriate means the bottoms of the tubular elements 18 may be supported so that they automatically with the Pipe elements 18 is driven. Such funds are for. B. in Fig. 3 schematically illustrated support legs 34. Further, other than the illustrated substructures be provided, in particular those which instead of the push rods, the tube 10 enclosing Pipe sections, lattice girder or other structures have and are statically sufficiently stable.
- driver elements can be provided be, for.
- those with the help of spring elements from the butt joints be driven out between the pipe elements as soon as the guide and transport pipe 10 is pulled out of the pipeline.
- the driver elements at the rear ends of the bar sections and arranged so that they Do not obstruct the insertion of the tube elements, or the driver elements in middle Instead of providing at the ends of the rod sections, in which case the Rod sections each partially associated with two consecutive pipe elements would.
- the driver elements by extruder welding od.
- the driver elements by extruder welding od.
