Definitions

  • the invention relates to a device for sealing a rock wall, which device comprises an injection tube adapted to be introduced into a bore hole in the rock wall, into which bore hole a filling material is intended to be injected through the injection tube
  • the device may also comprise a reinforcement rod, e.g. a conventional reinforcement bar, so that both a sealing effect and a reinforcing effect is achieved through the use of the device.
  • a reinforcement rod e.g. a conventional reinforcement bar
  • the invention is utilized in the construction of tunnels and other rock cavities.
  • reinforcement of the rock wall is most often required to increase the strength, and sealing of cracks and the like to prevent damp and water from penetrating the tunnel or cavity.
  • Known methods of reinforcement consist in providing the rock wall with evenly dispersed bore holes, which can have a diameter of about half a decimetre and a depth of about 1-6 metres.
  • the rock must instead be sealed in a first stage, a rubber plug or tap normally being arranged in the bore hole opening and the hole being filled with concrete or cement which is then allowed to solidify. Following this, a hole is drilled in the concrete/cement which is reinforced in the same way as described above.
  • the method comprises several stages and it is nevertheless not entirely certain that the reinforcement remains in place
  • SE-A-509139 (WO 98/45576) shows a device for reinforcing and sealing a rock wall, which device comprises a reinforcement bar adapted to be introduced into a bore hole in the rock wall, into which bore hole a filling material is intended to be injected.
  • the device also comprises a non-return valve for the filling material.
  • the device requires several operational steps for the introduction into a bore hole and filling of the same. Accordingly, an injection nozzle must first be applied, where after the bolt itself is inserted via a hole in the injection nozzle.
  • the invention is mainly described in connection with a device which is adapted to both seal and reinforce a rock wall. It is however to be understood that the invention also relates to a device which is adapted to seal but not to reinforce the rock wall, in which case the device does not comprise a reinforcement rod or anchoring means.
  • the aim of the present invention is to offer a device for reinforcing and sealing a rock wall, by means of which device the aforementioned disadvantages are avoided or at least minimized, it being possible to carry out reinforcement and sealing of the rack wall in just a few stages, meaning that the reinforcement remains securely in place at the same time as sealing of water-bearing cracks leading into the bore holes is achieved and air bubbles in the cement are avoided.
  • a device for reinforcing and sealing a rock wall which device comprises a reinforcement rod, e.g. a conventional reinforcement bar intended to be introduced into a bore hole in the rock wall, into which bore hole a filling material is then injected, said device also comprising a non-return valve for the filling material.
  • the non-return valve is adapted to withstand a positive pressure of the filling material in the bore hole. The filling material is thus injected under positive pressure, at which any cracks in the rock leading into the bore hole are sealed.
  • Said non-return valve consists of a sleeve which encloses an injection tube provided with outlet openings, which injection tube is preferably joined to said reinforcement bar or equivalent.
  • a reinforcement bar which forms part of the device is described by the number 1.
  • the reinforcement bar in the figure is cut away at the top but in reality has a length of about 0.5-10 m, preferably 1-7 m and even more preferredly 2-5 m.
  • the device is shown as it is arranged in a vertical, upwardly directed bore hole in the roof of the tunnel or rock cavity, which position is used in the further description.
  • the device can just as well be used in a horizontal hole, an angled hole or in a vertical, downwardly directed hole.
  • the reinforcement bar 1 has a strongly profiled surface for fastening securely in the cement or concrete, henceforth termed filling material, which will enclose the same.
  • an injection tube 3 Joined as an extension of the reinforcement bar arranged at the bottom, via a coupling sleeve 2 welded firmly at both ends, is an injection tube 3 which accordingly has an inner longitudinal cavity and is open at the bottom for the connection of hosing for filling with the filling material.
  • the non-return valve 4 Arranged a distance below the coupling sleeve for the reinforcement bar 1 and the injection tube 3 is a non-return valve 4.
  • This non-return valve 4 is adapted to withstand a positive pressure of the filling material when this is injected under positive pressure into the bore hole via the non-return valve Thanks to this non-return valve, the filling material does not run out of the bore hole before it solidifies, in spite of the positive pressure.
  • the non-return valve 4 preferably comprises a rubber sleeve 5 which encloses a part of the injection tube 3. In the area of the rubber sleeve the injection tube has a number of outlet openings 6 for the filling material.
  • the rubber sleeve which can of course also be manufactured from another, to some extent elastic, strong material, is suitably formed as an envelope of a truncated cone, having a first diameter at the bottom and a second, smaller diameter at the top.
  • the rubber sleeve 5 is vulcanized firmly at an internally threaded eye nut 7, which in turn is screwed firmly on an externally threaded ring fastener 8.
  • the ring fastener 8 encloses the injection tube 3 and is welded firmly to the same.
  • the ring fastener 8 also has a flange 9 at the bottom, on the upper surface of which flange the eye nut 7 rests.
  • the upper, smaller diameter of the rubber sleeve 5 is adapted to end sealingly around the injection tube 3.
  • the nose is suitably provided with a few, e.g two, internal lip seals consisting of O-rings which are set into the rubber sleeve, or by a few continuous projections on the inside of the rubber sleeve in the tip part.
  • the injection tube is enclosed by a narrow tube 13 with an upper flange 14 which lies close to the lower surface of the flange 9. Resting against the lower surface of the flange 14 is the upper short end of a seal in the form of a sleeve 10 which suitably also consists of rubber.
  • This rubber sleeve 10 encloses a part ofthe lower section ofthe injection tube surrounded by the narrow tube 13, its lower short end resting against a washer 11 which in turn rests against a nut 12.
  • the injection tube 3 and/or the narrow tube 13 are threaded externally with the same thread size as the nut 12.
  • a top piece forming an expander Arranged in the upper part of the device, suitably at its top, is a top piece forming an expander.
  • the expander is shown in Fig. 2, which forms a continuation of the device shown in Fig. 1, a longer piece of the reinforcement bar 1 (only partly shown) connecting the part according to Fig. 1 to the part according to Fig. 2.
  • the expander is joined to the reinforcement bar by means of a sleeve-shaped spacing piece 21 which is welded firmly at the bottom on the end of the reinforcement bar and which at the top contains an internal thread. Screwed into this thread is a coupling pin 22 which consists of a straight pin provided with external thread at least a distance at the bottom and a distance at the top.
  • the coupling pin 22 is partly screwed - in the unexpanded state - into a hole provided with an internal thread in a core part 23.
  • the hole here is sufficiently long to permit further screwing in when anchoring of the device into the rock is to be executed, which will be described in greater detail.
  • the core part 23 tapers off at the top into a short conical piece 24 and is threaded externally above this conical piece, a top cone 25 enclosing the conical piece 24 and a part of the upper section of the core part 23.
  • the top cone 25 has an internal bevel at the bottom which is adapted according to the conical piece 24 of the core part 23.
  • a top nut 26 Arranged above the top cone is a top nut 26 to hold the top cone firmly.
  • lock washers 27 are fastened around the core part 23.
  • a lock washer of this kind is shown in its level state in Fig. 3 and consists of a washer provided with a number of slits 41, preferably 2-10, suitably 4-7
  • these lock washers are fastened over the conical piece 24 of the core part, they assume the form of an envelope of a truncated cone.
  • a loose sleeve 28 Arranged under these lock washers, surrounding the upper part of the coupling pin 22 and the lower part of the core part 23 is a loose sleeve 28 with an inwardly facing flange 29 arranged at the bottom. This flange 29 rests against the upper short end of the spacing piece 21.
  • cam steel which can be hot-galvanized or surface-protected in another way.
  • Fig. 3 shows as stated a lock washer 27 in its level state.
  • the slits start out from the washer's circumference, extending almost, but not completely, in towards the inner bore diameter of the washer and suitably having a certain, inwardly tapering width and a radius furthest in.
  • the inner bore diameter of the washer is suitably provided with a shorter straight piece 42, to prevent the washer from rotating when it sits on the core part 23.
  • the lock washers are suitably manufactured from cold-rolled, hardened steel of a thickness of 0.1 - 1 mm, preferably 0.2 - 0.7 mm and even more preferredly 0.3 - 0.45 mm.
  • the washer has an outer diameter of about 60 mm and an inner bore diameter of about 20 mm.
  • the function of the device is as follows. A hole 30, Fig. 4, is bored into the rock wall, of at least the same length as the length of the device. The device is introduced into the bore hole so far that the washer 11 and nut 12 will be located at the mouth of the bore hole. After this, the injection tube 3 is rotated a number of revolutions, suitably by means of a hydraulic device which grips the part of the injection tube sticking out of the bore. The rotation thereby extends to the reinforcement bar 1 and further to the sleeve-shaped spacing piece 21 which is joined to the upper part of the reinforcement bar.
  • the upper part of the coupling pin 22 is screwed further into the threaded hole in the core part, at which the upper short end of the spacing piece presses on the lower flange 29 of the sleeve 28 so that the sleeve is pressed upwards against the lock washers 27.
  • the sleeve 28 will then act as a pressing device on the lock washers so that their shape of an envelope of a truncated cone is at least flattened out somewhat.
  • the circumference of the lock washers will hereby be pressed firmly into the walls of the bore hole so that the entire device is anchored in the rock.
  • the next stage is to seal the bore hole with the device contained therein at the bottom by tightening the nut 12 so that the rubber sleeve 10 is compressed in an axial direction, at which it expands in a radial direction to seal between the injection tube 3 and the lower walls of the bore hole.
  • Fig. 4. A pipe (not shown) can now be connected to the injection tube and the filling material 31A is injected under positive pressure, at which the filling material flows out of the outlet openings 6 in the injection tube and penetrates into the bore hole at the upper diameter of the rubber sleeve 5.
  • the rubber sleeve 5 acts here as a non-return valve integrated into the device so that the filling material, in spite of being under positive pressure, cannot run back out of the bore hole before it manages to harden Beneficially, there is also arranged a small diameter conduit 35, e.g. of a hydraulic tube type, which mouths in the most distant region of the bore hole 30. Preferably it ends upstream of the spacing piece 21.
  • the conduit 35 is adapted to act as a degassing conduit which leads air and gasses out of the bore hole as the filling material is introduced. During introduction of the filling material, the open end, adjacent the entry of the bore hole, of the conduit 35 is sealed when filling material starts to continuously come out of the conduit, whereafter the introduction of filling material into the bore hole can proceed under a positive pressure.
  • filling material Due to the positive pressure, filling material is also caused to penetrate any cracks 32 leading into the bore hole, in spite of the fact that these cracks may be water-bearing.
  • desired positive pressure which may reach about 100 bar positive pressure or suitably about 50-80 bar positive pressure
  • the pipe connection can be detached, at which the filling material 31A can be left to harden under positive pressure, thanks to the non-return valve 4 and the rubber sleeve 10.
  • the nut 12 is unscrewed the washer 11 removed and the rubber sleeve 10 is taken out of the hole by means of the narrow tube 13 provided with a flange.
  • the space below the flange 9 is then filled with filling material 31B (Fig. 5) by providing the opening of the bore hole with a larger washer (not shown) with a hole in one side for filling with filling material an being made to evacuate the hole via an air pipe. If the risk of corrosion is not great however, the narrow tube 13 provided with a flange can be left out of the device, in which case the rubber sleeve 10, washer 11 and nut 12 can instead remain permanently in place after the device has been applied to the bore hole.
  • the opening of the bore hole and its immediate surroundings are then covered in a conventional manner with a plate disc or washer 33, which is pressed against the rock wall by means of a nut 34, which is screwed on to the protruding part of the injection tube.
  • a relatively simple and cheap construction is achieved for sealing and a non-return valve function which thus permits filling material to be injected into a bore hole and allowed to harden under a favourable positive pressure
  • the relatively simple and cheap construction also allows the seal, non-return valve and expander to be cast in the bore hole and thereby form an admittedly permanent but nevertheless disposable material without incurring costs which are too great Corrosion-promoting air bubbles close to the reinforcement bar are counteracted due to the positive pressure.
  • a further advantage of the device according to the invention is that it can be used for filling material of varying viscosity or dry content according to the circumstances and preference.
  • the embodiment of the invention which is a device for sealing the rock wall without reinforcing it, corresponds fully to the lower part of the device shown in figures 1, 4 and 5. Accordingly, the device of the embodiment in Fig. 6 does not comprise a reinforcement rod nor anchoring means. Instead, the injection tube 3 ends just downstream the non-return valve 4 with a blind end wall 3A.
  • filling material can be introduced into the bore hole under a positive pressure, and be allowed to harden under a retained positive pressure, thus achieving a good seal of cracks 32 that mouth in the bore hole.
  • This embodiment of the invention is preferably used in rocks that are relatively strong, but water leaking.
  • the invention is not restricted to the embodiment described above but can be varied within the scope of the following patent claims.
  • the expert thus easily perceives that e.g. the expander for anchoring the device in the rock can be executed in a number of different ways, some of which belong to the prior art.
  • the sealing and reinforcing device can possibly even be used entirely without anchoring.
  • the non-return valve 4 and the rubber sleeve 10 can also be conceived to be executed in other ways and in other materials
