Definitions
- the invention relates to a pipe section made of reinforced steel concrete according to the preamble of claim 1.
- Such pipe sections are pushed into the ground by means of pressure presses, the presses being retracted after insertion of a first pipe section, a second pipe section being placed in the press shaft on the first pipe section and then being pushed in by means of the press.
- a steel sleeve For the liquid-tight joining of the successive pipe sections, it is known to arrange a steel sleeve on the rear end of a pipe section, based on the feed direction, which overlaps the axial end of the pipe section.
- the outer diameter of the steel sleeve is slightly smaller than the outer diameter of the pipe section and is fixed in the overlapping area by means of anchors in the pipe wall.
- a plurality of radially projecting anchors are provided, preferably with equidistant distances from one another.
- a pipe section to be attached engages with its reduced diameter end in the steel sleeve, wherein an elastic sealing ring, a joint tape or the like is arranged in a circumferential groove or on a step fold of the connection end in order to ensure a liquid-tight connection.
- This pipe connection generally has sufficient tightness up to pressures of 0.5 bar. At higher pressures, leaks occur between the pipe section and the steel sleeve anchored to it. An elastic seal is therefore arranged between the steel sleeve and the pipe anchored to it, or a joint tape is provided on the butt joint of successive pipe sections. Nevertheless, it had to be determined that leaks at higher pressures could not be ruled out with certainty. A permissible maximum pressure of 1.5 bar is therefore often given for pressurized lines manufactured using the pre-compression process. If a line is laid in the pre-compression process in nature or water protection areas under water or other increased requirements, higher pressure tightness must be guaranteed; the same applies to pressure lines to be manufactured using the jacking method.
- the invention has for its object to develop prepress tube sections of the generic type such that a high pressure resistant connection of the steel sleeve to the tube wall is guaranteed.
- the circumferential profile arranged radially on the inside in the region of the end of the sleeve facing the pipe section represents a highly effective circumferential seal based on the principle of a labyrinth seal, whereby at the same time a mechanically intimate connection with the pipe wall is achieved.
- This combination of pipe section and steel sleeve can have a water pressure resistance of 5 bar and more.
- the arrangement of the circumferential profile which is preferably made of steel and is welded to the inner wall of the steel sleeve, enables high-pressure-resistant connections which can also withstand pressures, in particular alternating pressure loads of up to 5 bar and more.
- the inner profile preferably ends axially at the plane determined by the end face of the inner end of the sleeve, which ensures that the prefabricated sleeves are easy to handle, since no parts projecting beyond the axial end face of the sleeve sleeve occur.
- a first pipe section 1 is extended by attaching a second pipe section 2 and pressed in the feed direction 3 by applying an axial force.
- Each pipe section 1, 2 consists of reinforced reinforced concrete, the ends 1a, 1b and 2a, 2b of the pipe sections being designed as connecting ends.
- the - in relation to the feed direction 3 - rear connection ends 1b, 2b have a steel sleeve 5 anchored in the pipe wall 4, which overlaps the connection end 2a of a pipe section 2 to be attached.
- the outer diameter d of the steel sleeve 5 is slightly smaller than the outer diameter D of the pipe section 1 or 2.
- the steel sleeve 5 is thus within the envelope curve determined by the outer pipe surface.
- the steel sleeve 5 overlaps the end section 4a of the pipe 1 with a reduced diameter, the sleeve 5 overlapping the pipe section 1 over approximately 40 to 50% of its length.
- the steel sleeve 5 is fixed in the tube wall 4 by means of anchors 6, in particular head anchors. 3 and 4 show, a plurality of anchors 6 are provided over the circumference of the steel sleeve 5, which preferably have equidistant distances from one another. From Fig.
- the armatures 6 have a first approximately radially projecting section 6a, to which a section 6b projecting radially inward and axially to the inner end 5a of the sleeve 5 connects, the free end of which has an anchoring head 6c.
- the sections are made of round material. It may be appropriate to arrange the anchors 6 at an incline or to use flat steel concrete anchors.
- the reduced diameter connecting section 2a of the pipe section 2 to be attached lies with radial play within the sleeve 5, a seal 7 being arranged inside the sleeve 5 to seal the connecting end 2a.
- the seal 7 lies in an outer circumferential groove 7a (FIG. 2) of the connection end 2a and can also be formed by an elastic joint tape or the like. Instead of a circumferential groove 7a, a step fold is also expedient, as indicated in FIG. 1.
- the sleeve 5 is provided in the region of its inner end 5a facing the tube section 1 with a radially inner circumferential profile 10, which is made of steel and welded to the inside of the sleeve 5 is.
- the welded connection 11 is preferably made liquid-tight.
- the circumferential profile 10 is cast in the reinforced concrete of the tube wall 4, whereby a type of labyrinth seal is formed, which ensures a watertight connection between the steel sleeve 5 and the tube 1 carrying it. Even with strong temperature fluctuations, which are not unproblematic due to the different thermal expansion coefficients of the steel sleeve 5 and the pipe sections 1, the tightness is not impaired. Both an internal water pressure and an external water pressure of 5 bar and more are possible.
- the circumferential profile 10 defines a radial plane 9 on which the tube axis 19 is perpendicular.
- the profile 10 also has a radial height, which preferably corresponds to approximately 25% of the thickness of the tube wall 4. In particular, the profile extends over a radial depth of approximately 60 mm.
- both the inner profile 10 and the head anchors 6 end axially at the plane 8 determined by the end face of the inner end 5a of the sleeve. So there are no parts above the frontal plane 8 of the cuff which could interfere with the transportation or handling of the prefabricated cuff 8.
- the circumferential profile 10 is preferably close to the inner end 5a of the sleeve 5, while the head anchors 6 lie adjacent to the axial end of the tube wall 4 within the sleeve 5.
- the profile can be a radial, circumferential web or an I-profile.
- the profile is preferably an angle profile, in particular an L profile, as shown in the exemplary embodiment.
- the longer leg 10a of the L-profile projects radially into the tube wall 4, the leg 10a being fixed vertically on the inner surface of the sleeve 5.
- the short profile leg 10b is arranged at the free end of the vertical leg 10a and projects in the direction of the inner end 5a of the cuff; the shorter leg preferably runs parallel to the tube axis 19 and ends at the plane 8 defined by the end face of the inner end 5a. If an even more pressure-resistant circumferential seal is to be ensured, this can be done Profile 10 radially extended or expediently in the form of a T-shaped profile.
- the pipe sections can be laid in the open trench as well as in the jacking or pre-pressing process.
- a compensating disk in particular a softwood disk 15, is expedient between successive pipe sections 1, 2.
