Definitions

  • the invention relates to a pressure-tight pipe connection for a pipe made of a number of steel pipe sections, manufactured in the pre-pressing process with a primarily no longer accessible cross-section, in which the pipe sections, each a spigot end and a sleeve end formed by a steel ring connected to the pipe with an angular cross-section have, can be connected to each other in a pressure-tight manner by plugging into one another, the longer leg of the sleeve extending in the pipe axis protruding beyond the pipe end and the shorter leg running at right angles to the pipe axis and the outer diameter of the sleeve being smaller than the inner diameter of the jacking pipe.
  • underground pre-compression processes can be used, which work either on the soil displacement or the soil extraction principle.
  • Protective or product pipes are pressed or retracted into the cavity, either by displacing the floor or by removing the floor, immediately or after completion of the cavity.
  • thin-walled jacking pipes usually made of steel, must first be pressed into which the product pipes are then pulled or pressed. The annular space between the jacking pipes and the product pipes is filled in subsequently. The jacking pipes cannot be recovered; You are lost.
  • jacking pipes that have been lost must be designed and connected to one another in such a way that they are pressed correctly and can follow the opened cavity as an articulated chain.
  • a pipe connection that is tight against pressurized water and that enables the safe absorption of any transverse forces that may occur is necessary above all below the groundwater table.
  • the shorter leg of the angular steel ring continues the cross section of the pipe section with which it is butt-connected; the longer leg forms the sleeve (special print from "Civil Engineering - Civil Engineering - Road Construction", No. 2 + 3, 1983, pp. 3 to 10).
  • the spigot end of the subsequent pipe section is supported directly against the steel ring, so that the driving force is passed through the steel ring and its connection to the pipe section.
  • the steel ring must therefore have a fit, which requires a correspondingly complex manufacture.
  • the tip end of a pipe section is formed on a steel ring welded to the inside of the pipe wall and can be inserted into an end groove on the socket end of the subsequent pipe section (DE-A 3 222 880).
  • An intermediate sleeve of this type consists of two annular, telescopically displaceable parts, one of which is detachably connected to the jacking pipe and the other to the product pipe.
  • a sealing ring is arranged between the mutually displaceable areas of these parts (DE-A 2 720 039).
  • the invention has for its object to provide a socket connection for a pipeline of the type specified, in which the individual pipe sections have the possibility during propulsion to follow the opened cavity as a pressure-resistant articulated chain, but the socket connection itself should remain unloaded by longitudinal forces, which furthermore is pressure-tight against water and also ensures the required positive locking.
  • this object is achieved in that the shorter leg forming a flange is attached to the inner wall of the pipe section shortly before the actual end of the pipe section, e.g. is welded, and that the longer leg forms with its outer surface a sealing surface for a sealing ring which is arranged on the inner surface of the tip end of the pipe section to be connected and is supported against a shoulder of an abutment arranged on the inner surface and that in the region of the pipe joint a radial guide for Prevention of transverse displacements of the pipe ends is provided.
  • the longer leg of the steel ring expediently has a wedge-shaped run-up at its outer end.
  • the radial guide to prevent transverse displacements of the pipe ends expediently consists of guide blocks which are attached to the outer surface of the longer leg of the steel ring and distributed evenly over the circumference.
  • the guide blocks can have a wedge-shaped run-up at their outer end.
  • the tip end of a pipe weft can be chamfered on the outer surface.
  • the shoulder for supporting the sealing ring is expediently formed on a flat iron ring which is attached to the inner surface of the pipe end at the tip end at a distance from its end, e.g. is welded on.
  • the advantage of the invention is seen essentially in the fact that a simple possibility has been created with economic means, a pipe pipeline while maintaining an immediate pressure-resistant butt joint of the pipe sections with transmission of the jacking force within the cross-section of the pipe wall when jacking as jacking pipe in the event of deviations from the jacking axis to allow certain angular changes to follow in the manner of an articulated chain - while maintaining the seal and the positive locking.
  • the sleeve connection is not loaded by axial forces and, since the sealing ring acts between sealing surfaces parallel to the pipe wall, offers sufficient freedom of movement.
  • Both the approach shaft A and the target shaft Z can be produced in a manner known per se by installing sheet pile, slotted or pile walls or the like and excavating the ground.
  • the shaft bottom is below the groundwater level 2.
  • Both the approach shaft A and the target shaft Z each consist of a shaft wall 3 and a base plate 4. In the wall 3 of the start shaft A there is an opening 5 for the passage of the jacking pipe 6, which is provided with a sliding seal.
  • the advance pipe 6 is pressed by means of a drilling device 7 with a drilling head 8 which is pressed against the face in the direction of arrow 9 and which causes the soil to be broken down in a rotating movement and / or by rinsing with water.
  • the driving force required for the pre-pressing of the jacking pipe 6 is generated in the approach shaft A by hydraulic presses, the effect of which is indicated by an arrow 10.
  • FIG. 2 and 3 each show in a detail from a longitudinal section through one of the pipe joints 11 (Fig. 1) on a larger scale the formation of a pipe connection according to the invention.
  • the connection of two pipe sections 6a and 6b is shown, only the socket end 12 of the pipe section 6a and the spigot end 13 of the pipe section 6b being shown.
  • an angular steel ring 15 is fastened to the inside of the pipe section 6a shortly before its actual end 14, which consists of an axially extending longer leg 16 and a shorter leg 17 extending at right angles to it. With the end of this shorter leg 17, the steel ring 15 is welded to the inner wall 18 of the pipe section 6a.
  • the longer leg 16 has a wedge-shaped run-up 20 on its outer surface 19, which also acts as a sealing surface.
  • a flat iron ring 23 is welded to the inner wall 21 of the pipe section 6b at a distance from its end 22, the outer, radially extending end face 24 of which forms a shoulder for a sealing ring 25.
  • the sealing ring 25 itself consists of a lower contact part 26, with which it rests on the inner wall 21 of the pipe section 6b and is supported against the shoulder 24, and an upstanding bead 27, which in the pre-pressing direction (arrow 9) has an oblique contact surface 28 and on the Back has a recess 29.
  • the pipe connection is created when two pipe sections are pushed together when a new pipe section is placed in approach shaft A.
  • the sealing ring 25 with the inclined contact surface 28 initially slides onto the wedge-shaped section 20 of the steel ring 15, as a result of which the pipe section 6b is roughly centered.
  • the bead 27 of the sealing ring 25 onto the contact surface 20 of the bead 27 it is folded against the pre-pressing direction.
  • the bead 27 rests on the contact part 26, that is to say the recess 29 is closed.
  • the sealing ring 25 acts like a one-piece, compact profile.
  • Guide blocks 30, which are arranged as evenly as possible on the outer surface 19 of the steel ring 15 directly between the end faces of the pipe sections 6a, 6b (FIG. 6a, 6b) serve to center the tip end 13 when the pipes are pushed together and to secure the transverse connection 3 and 4).
  • the guide blocks 30 are expediently welded to the steel ring 15.
  • the guide blocks 30 also have a wedge-shaped run-up 32 at the outer end, onto which the front end 22 of the tip end 13 of the pipe section 6b can slide when the pipes are pushed together.
  • the tip end 13 of the pipe section 6b is provided with a chamfer 33 at the outer end so that, when further transverse movements should occur during the course of the advance, the sliding resistance of the jacking pipe in the ground is not by a shoulder, albeit a low one.
