Definitions

  • the present invention relates to a method for lining a well or a pipe, in which a lining comprising a number of panels with means at their side edges for mutual assembly in not assembled state is introduced into the well or the pipe, whereafter the panels are assembled to a self- supporting cylinder which is placed in the well or the pipe, following which the gap between the well or the wall of the pipe and the cylinder is filled with a hardenable material, like for instance concrete.
  • WO-A-911563 describes a method, in which a lining is built up by a number of small, rigid, semi- circular ring elements which are stacked by pairs on top of each other to a desired height.
  • the object of the invention is to provide a method, by which a well or a pipe may be quickly and effectively provided with a lining.
  • the panels used are flexible profile-panels with longitudinal ribs on one side face, said ribs extending in the assembled state of the cylinder in the longitudinal direction of the well or the pipe, and in that the assemblies run parallel to the ribs.
  • the non-assembled panels may contrary to a complete cylinder be introduced through an opening, which is substantially smaller than the cross-section of the well or the pipe to be lined, for which reason it is not necessary for the access to be the size of a full cross-section.
  • the panels are assembled prior to introduction into the well or the pipe to form a flat object which is rolled around a longitudinal axis to a diameter smaller than the diameter of the entrance of the well or the pipe.
  • This possibility does not exist with the method according to WO-A-9115634 because the elements used there are rigid.
  • Spacers are preferably provided between the cylinder and the wall of the well or the pipe prior to the filling with hardenable material, and the cylinder is preferably supported in the interior by provision of foldable, extendable support rings along the interior face of the cylinder prior to the filling of the gap between the cylinder and the wall of the well or the pipe.
  • the invention relates to a support ring for use when carrying out the method, which support ring comprises at least two curved, rigid bracket members which by means of joints are mutually connected to form an open ring, and which at their free ends comprise a means for pressing these two ends apart and fixing them relative to each other.
  • a support ring may like the lining workpiece be introduced through an opening which is substantially smaller than the cross-section of the well or the pipe in order to be extended to abut the inner face of the cylinder and to support the latter and create an abutment against the pressure from the hardenable material. After the at least partial hardening of the hardenable material, the support ring may be made to collapse and can be removed without damaging the lining.
  • Fig. 1 is a section through a well which has been provided with a lining
  • Fig. 2 the profile of a panel which is suitable for use in the method according to the invention
  • Fig. 3 is a support ring for use in practising the invention.
  • Figs. 4-8 is a device for keeping the two free ends of the support ring apart and for fixing them.
  • Fig. 2 shows the profile of a lining panel 1, which is suitable for use when carrying out the method according to the invention.
  • the lining panel 1 shown ' is marketed under the name CON-PLAST and is made from PVC.
  • the lining panel may have a thickness of for instance 2-2.5 mm.
  • the lining panel 1 is provided with Y-shaped ribs 2 which may protrude for instance 12-15 mm from the surface of the panel and which may be embedded in for instance concrete to bond the lining 1 thereto.
  • the lining panel 1 is provided with a bead 3 which may be pressed into a corresponding slot 4 at the opposite side of an adjacent lining panel to assemble two lining panels.
  • Fig. 1 shows a well which consists of three well rings 5 and which ends in a cone 6 and a manhole 7. At the bottom the well ends in a banquette 8 with a groove 9 connected with a pipe 10.
  • a cylinder 11 is inserted into the well, which cylinder consists of lining panels 1, the number of which depends on the diameter of the well and the width of the panels, which for instance may be 30 cm. This width has, however, no importance as such for the invention.
  • concrete 12 has been cast, and in Fig. 1 support rings 13 are shown which support the cylinder 11 against the pressure from the concrete 12.
  • the upper one of the support rings 13 is provided with hooks and is suspended in the upper edge of the cylinder 11.
  • the remaining support rings 13 are suspended in the uppermost support ring by means of chains 14.
  • the support rings 13 may for instance be designed as shown in Figs. 3-8, where Fig. 3 shows the entire support ring 13, which consists of two rigid, curved bracket parts 15 which are mutually connected by means of a joint 16. This should make it possible to fold the two bracket parts towards each other and to prevent the two ends at the joint 16 in the shown position cannot be moved towards each other. It is, however, not a requirement that the two ends cannot be drawn apart.
  • Figs. 4 and 5 shows from the side and from above, respectively, a wedge 19 which is adapted to be inserted between the obliquely cut ends 17 to press them apart, thereby expanding the support ring 13.
  • the wedge is provided with a threaded spigot 20 for fastening onto the fish plates 18 by means of a disc 21 and a nut 22.
  • Fig. 8 shows the ends 17 of the bracket parts 15 with the wedge 19 in position.
  • Fig. 1 Prior to the situation in Fig. 1 the lining panels 1 were assembled to a plane, coherent workpiece.
  • the profile of the banquette 8 along the wall of the well was recorded, and the workpiece made from the lining panels was cut correspondingly at one end and in such a way that a desired height was obtained.
  • the workpiece was rolled into a roll with smaller diameter than that of the manhole 7.
  • the roll was then lowered into the well and unrolled, following which the vertical sides of the workpiece were pressed together to form the cylinder 11.
  • Spacers not shown are used for centring the cylinder 11 in the well. These spacers may easily be fastened to the Y-shaped ribs 2 of the lining panel, and they are for instance placed at the top and at the bottom of the cylinder 11.
  • spacers may also be placed at the centre of the cylinder 11.
  • Very deep wells (for instance more than 3 m) are renovated by means of several cylinders which are placed on top of each other in a corresponding number of working steps, i.e. one cylinder is placed and then casting takes place, following which the next cylinder is placed on top thereof, when the concrete behind the first cylinder has hardened.
  • one cylinder is placed and then casting takes place, following which the next cylinder is placed on top thereof, when the concrete behind the first cylinder has hardened.
  • an undesirable high hydraulic pressure at the lower end of the cylinder is avoided.
  • Collapsed support rings 13 were then taken down the manhole 7, positioned, unfolded and expanded to the position shown in Fig. 3, in which they abut the inner wall of the cylinder 11 to keep the cylinder 11 expanded during the subsequent pouring of concrete 12 in the gap between the well rings 5 and the cylinder 11. Vibration against the support rings 13 and the inner surface of the cylinder 11 is carried out. When the concrete 12 has at least partially hardened, the support rings 13 is removed, and the lining is finished.
