Definitions
- the invention relates to a method for laying installation objects, in particular at least one line and / or an empty pipe, on the inner wall of a laid sewer pipe according to the preamble of patent claim 1 and to a device for carrying out such a method with the features of patent claim 12.
- inliners namely inner linings in the form of a flexible plastic hose
- a ready-made, resin-impregnated carrier material in the form of a tube for example a woven or laid tube, is pressed against the inner wall under pressure.
- Insituform process a flexible needle felt hose soaked with synthetic resin is introduced into the sewer to be renovated with water or compressed air using the inversion process, also called the inversion process, and pressed against the inner wall of the sewer. After being turned inside out, the resin is on the outside of the hose, where it bonds to the inside wall of the duct when it hardens.
- the inliner or the lining must be cut open to ensure that Fluidically reconnect the branch pipe to the sewer pipe.
- WO 99/65129 proposes to insert a tubular or tubular liner into the installed sewer pipe, at least one flexible empty pipe and / or a pipe being arranged on the outer surface thereof.
- the inliner is drawn into the sewer pipe together with the installation object in the folded state, the installation object being located on the top of the folded hose.
- the disadvantage of this is that when the hose is expanded there is no possibility of guiding the installation object to a specific point on the inner wall of the sewer pipe. Therefore, in cases in which the inner lining in the region of the junction parts of branch pipes has to be cut open subsequently, there is a risk that the empty pipe and / or the line will also be cut.
- a protective tube receiving data cable is either inserted into a protective strip or into a lining liner, the protective strip or the liner is impregnated with a resin forming a matrix and then inserted into the sewer pipe.
- the inliner or an expansion hose is stretched to the full contact with the inner wall. After the matrix has hardened, the expansion hose is removed.
- the disadvantage of inserting the installation object in the inliner is that the position of the installation object can only be checked with difficulty or not at all.
- the other variant has that
- a method according to the preamble of claim 1 is known from DE-A 198 61 090.
- a laying object for example all types of cables, in particular electrical and / or optical waveguide cables, or empty pipes for such cables, is laid in a sewer pipe with a laying robot which can be moved in the sewer and fastened to the inside wall of the sewer.
- the operator can determine the optimal laying line at the control station and control the robot so that the laying object is fastened to the wall along this line in a custom-made bed, for example by gluing, anchoring or bracket fastening.
- the method is relatively complex since, in addition to a controllable guiding device, the laying robot must also have devices for fastening the laying object.
- the laying robot has, for example, a pretreatment tool for pretreating the wall, an adhesive bed application device and a pressing device.
- the invention is therefore based on the object of providing a method of the type specified at the outset, with which the installation object can be fitted in the sewer pipe with reduced outlay on equipment.
- the invention is also based on the object of specifying a device for carrying out such a method. On the process side, this object is achieved by a method having the features of patent claim 1 and on the device side by a device having the features of patent claim 12.
- Advantageous further developments are the subject of the respective subclaims.
- the installation object in particular at least one line and / or an empty pipe or a carrier tape with at least one integrated line and / or an empty pipe, is guided to the inner wall in a controlled manner in the longitudinal and transverse directions of the sewer pipe.
- the attachment and fastening of the at least one line or the empty pipe is therefore no longer almost arbitrary, but can be influenced in a targeted manner and can therefore be brought about in a controlled manner.
- the attachment of the installation object is considerably simplified according to the invention by inserting a lining inliner into the channel.
- This process takes place continuously and / or in accordance with the inversion process. It is thus advantageously possible to dispense with an adhesive bed to be prepared beforehand and the pressing of the laying object into the adhesive bed.
- the laying device or guiding device which is preferably used solely for guiding the laying object, does not require any corresponding adhesive and pressing devices. It is advantageous in the sense of a double effect that the inliner on one side for lining the sewer pipe and on the other hand also serves to attach the installation object to the inner wall of the sewer pipe.
- the inliner is located outside the inliner, i.e. between the inliner and the inner wall of the sewer pipe, and is therefore protected by the inliner.
- an adjustable guide device is provided, by means of which the laying of the at least one line and / or the empty pipe in the longitudinal and transverse directions of the sewer pipe can be controlled in a targeted manner.
- the guide device With the aid of the guide device according to the invention, it is possible to attach the at least one line or the empty pipe to the desired location of the sewer pipe or the branch pipe.
- the guiding device which, in addition to guiding the installation object, does not have to perform any other functions and can therefore be of a light and mechanically simple construction, there are no further components, e.g. Pressing or gluing device, necessary.
- the guide device is preferably located directly in front of the inliner in the working direction.
- the inliner preferably moves through the sewer pipe by turning it inside out in the working direction by means of a pressure medium, taking new sections of the installation object to be laid from its front and pressing them against the inner wall of the sewer pipe.
- the guide device is moved in particular in the channel direction such that it maintains a defined minimum distance from the inliner during installation.
- the minimum distance is preferably a few centimeters, but can also Be zero, ie both components touch. It is also preferred that a certain maximum distance is not exceeded.
- the distance between the tip of the guide device and the lateral surface of the inliner or the distance between an assembly carriage and the front end of the inliner is used as the measurement variable.
- the controlled forward movement of the guide device ensures that only the installation object, but not the guide device itself, is enclosed between the inliner and the wall, since the guide device could be damaged, for example, by the adhesive on the outside of the inliner. It is also achieved that the installation object is actually positioned along the intended installation line.
- the minimum distance is maintained passively, for example, mechanically, in that the assembly carriage has a spacer against which the inliner abuts when it moves in the working direction and thus moves the assembly carriage forward. It is advantageous that the assembly cart does not need its own drive.
- a control device can be provided that measures the distance to the inliner or gives a signal when the distance limit is exceeded or undershot and initiates a corresponding movement of the guide device. For example, optical monitoring or a contactless sensor can be considered. A drive of the assembly vehicle is controlled by the control device.
- the installation object comprises a carrier tape in which at least one line and / or an empty pipe is integrated.
- the carrier tape is preferably a woven one Felt ribbon or a circular sewn knitted fabric. This ensures sufficient flexibility of the carrier tape until the adhesive has cured, so that it can be moved or rotated to the right or left without the spaced-apart inner lines and / or empty tubes kinking or crossing.
- the flexibility of the carrier tape also ensures that there is no overthreading of the lines even where it cannot be guided in a straight line.
- the carrier tape is only indirectly attached to the inner wall in that the liner is glued to the inner wall and solidifies when the adhesive mass hardens.
- mechanical overloading of the installation object due to different thermal expansion of the wall and the carrier tape or the installation object is avoided. This can occur if both components are firmly connected.
- This can be achieved by suitable selection of the process parameters, e.g. Type and amount of the adhesive, pressure when the liner is inflated, nature of the carrier tape, such that the carrier tape is largely completely impregnated with adhesive, but there is no adhesive connection to the inner wall.
- a carrier tape which is impermeable to the adhesive at least on its side facing the inner wall, e.g. by having an impermeable layer there.
- the laying object is advantageously led up a little along the branch pipe, along the circumference along the branch pipe and again led back or down to the sewer pipe.
- the installation object is constantly in contact with an inner wall, with the inner wall of the sewer pipe or with 'the inner wall of the branch pipe. Damage or even tearing off of the installation object as a result of the flowing medium and / or entrained solids is thus largely ruled out.
- the installation object is preferably guided to the right or left of the branch pipe.
- the installation object is thus located completely outside the flow cross section of the branch pipe and is therefore largely protected with respect to the medium flowing into the sewer pipe from the branch pipe. Otherwise, in this case, as in the former case, it is not necessary to provide a larger length of the line or of the empty pipe to bridge the branch pipe.
- the guide device can preferably be remotely controlled by means of a monitoring device in the form of at least one camera, for example a video camera.
- the device according to the invention can therefore be used particularly advantageously in non-accessible pipelines, such as sewer pipes.
- the position and the formation of branches can be determined in advance and the guide device can be controlled as a function of the determined result.
- the monitoring device preferably has one camera each in the working direction and counter to the working direction. This makes it possible to channel the sewer pipe on the one hand in the feed direction with regard to any branches that may occur and on the other hand against the working or feed direction, in particular with respect to that by means of the Observe the guide device for the specifically attached line or the empty pipe and / or the distance to the inliner. This enables you to react to junctions in good time and to lay the installation object in such a way that there is constant, intimate contact with the inner wall.
- the guide device has a rotatable or pivotable guide element, which guides the installation object like a slide tangentially to the inner wall of the sewer pipe or a branch pipe.
- the guide element preferably runs from the center of the channel to the inner wall, wherein it approaches the inner wall tangentially. It is preferably designed in such a way that it protrudes beyond the direction of advance of the assembly carriage. For example, it has a gooseneck shape.
- the guide device is optionally attached together with the monitoring device to an assembly carriage that can be moved in the sewer pipe.
- a sewer robot for example, as described in WO 99/43063, which is equipped with a suitable guide device, can be used as the assembly carriage.
- the assembly carriage preferably has a central passage for the installation object. This enables a wide range
- constructions without a central implementation are also conceivable, e.g. with a slide-like guide running above the car.
- An assembly trolley can easily be moved along the sewer pipe, this movement of the assembly trolley being able to take place automatically by means of its own drive or indirectly, for example by pushing.
- the guide device is securely positioned in the sewer pipe by the assembly carriage and can be moved in the longitudinal direction of the sewer pipe.
- the central bushing enables the line or the empty pipe, which is already in the sewer pipe in the working direction, to be guided to the guide device in a space-saving manner.
- a spacer is fastened to the assembly carriage, for example, below the guide device, against which the front of the inliner abuts.
- the guide device protrudes about as far as the spacer on the back of the assembly, which is directed against the working direction.
- the inliner can also be used to move the assembly trolley, so that it is not necessary to drive the assembly trolley by itself or an existing drive can be switched off.
- the assembly carriage with the guide device with its own drive motor.
- the spacer serves to ensure the necessary freedom of movement for the guide device so that it cannot come into direct contact with the inliner.
- the inliner can only exert a force indirectly on the guide device, namely via the assembly carriage.
- the adhesive is a wastewater-resistant synthetic resin, preferably an epoxy, polyester or vinyl ester resin.
- synthetic resins are readily available on the market and are sufficiently chemically stable.
- the adhesive is on the outside of the liner. This makes it possible to soak the carrier tape so that it then adheres to the outer wall of the liner. It is also advantageous that the carrier tape is only provided with the adhesive shortly before it comes into contact with the inner wall of the sewer pipe. It is thus possible to easily wind and unwind the carrier tape. In addition, it is automatically impregnated with the adhesive on the outside of the inliner during installation, so that a separate device for applying the adhesive to the carrier tape and / or prior impregnation of the carrier tape is not necessary.

- the guide device 5 and the monitoring device 8 are fastened to an assembly carriage 11, which can be moved in the sewer pipe 4 by means of a plurality of wheels 12, which can be located on the bottom side of the assembly carriage but also on its upper side.
- the assembly carriage 11 can have more than two wheels 12 on its base and more than one wheel 12 on its upper side or even no wheel 12 at all. It is possible to press the wheels 12 provided on the upper side of the assembly carriage 11 by means of springs against the inner wall 3 of the sewer pipe 4 in order to uniformize the running of the assembly carriage 11.
- the assembly carriage 11 can be designed with its own drive device, not shown, or, according to a preferred embodiment of the invention, also without its own drive device.
- the assembly carriage 11 has a central feedthrough 13 for the installation object 2.
- the central feedthrough 13 is shown greatly enlarged in FIG. 1 for the sake of a better overview and, according to another embodiment, can also be inclined or with rounded, front ends and rear sections.
- the front section of the assembly carriage in the working direction can, for example, be curved downward or rounded, and the opposite rear section of the assembly carriage can be curved upward.
- the guide device 5 is in the working direction
- an inliner 14 which is designed as an inner lining for the sewer pipe 4 in the form of a flexible plastic hose.
- the inliner 14 moves by means of a pressure medium, not shown in more detail, such as by water pressure or air pressure, by inverting in the working direction A through the sewer pipe 4.
- the inwardly drawn side 15 of the inliner 14 progressively moves outwards and ultimately forms the outside 16 of the inliner 14.
- the outside 16 then lies completely against the inner wall 3 of the sewer pipe 4.
- the inliner 14 receives new sections to be installed from the front 17 of the installation object 2 and, as shown in the area 18 in FIG. 1, presses them against the inner wall 3 of the sewer pipe 4. In the area 18 there is thus the installation object 2 in the annular gap between the liner 14 and the inner wall 3 of the sewer pipe 4, in FIG. 1 near the upper apex of the sewer pipe 4.
- the guide device 5 projects with its guide element 6 against the assembly carriage 11 on the opposite side thereof
- Working direction facing rear 19, i.e. in the direction of the inliner 14.
- a preferably basket-like spacer 20 is fastened to the assembly carriage 11, against which the front face of the inliner 14 abuts.
- the assembly trolley is moved in working direction A.
- the length of the spacer 20 measured in the channel direction essentially corresponds to the length by which the guide element 6 projects beyond the assembly carriage 11.

- targeted control of the laying object 2 in the longitudinal and transverse directions of the sewer pipe is possible by pivoting or rotating the guide element 6.
- the rotary movement of the guide element 6 is indicated by the double arrow C.
- the laying object 2 comprises a flexible carrier tape 23 that is receivable for an adhesive 22, which is, for example, a woven felt tape or a circular-stitched knitted fabric. At least one line or an empty pipe 2 'is integrated into this. 5 shows a cross section through such a laying object 2 schematically with five lines and / or guided parallel to one another
- the carrier tape 23 can be impregnated with the adhesive 22. Preferably, however, there is no permanent connection of the carrier tape 23 to the inner wall 3. As shown in FIG. 7, the carrier tape 23 can be provided with a layer 30 impermeable to the adhesive 22 on its side intended for contact with the inner wall 3, e.g. a slide.
- the adhesive 22 is, for example, a water-repellent synthetic resin, preferably an epoxy, polyester or
- the adhesive 22 is on the outside 16 of the inverted inliner 4, so that the carrier tape 23 only comes into contact with the adhesive 22 when it enters the gap between the inliner 14 and the inner wall 3 of the Sewer pipe 4 enters. Conversely, this means that the carrier tape 23 is not provided with the adhesive 22 in the area of the guide device 5 and the assembly carriage 11.

- the installation object 2 is introduced into the sewer pipe 4, provided with an adhesive 22 by the inliner 14, pressed radially against the inner wall 3 of the sewer pipe 4 and fastened there in this way. Before being enclosed between the inner wall 3 and the inliner 14, the installation object becomes 2 guided in the longitudinal and transverse directions of the sewer pipe 4 to the inner wall 3 in a controlled manner.
- FIG. 2 shows a plurality of branches 25 which open into the sewer pipe 4, the inliner 14 being located in the sewer pipe 4. This is indicated schematically in FIGS. 3 and 4.
- the installation object 2 or the carrier tape 23 with the integrated installation object 2 is located in the region of the upper apex on the inner wall of the sewer pipe 4, as is shown in the left part of FIG. 3, that is, before the branch 25.

- the dashed course 27 of the carrier tape 23 shown to the left of the branch pipe 7 in the plan view according to FIG. 4 corresponds to the left part of FIG. 3, that is to say that section of the carrier tape 23 which is still in front of the branch pipe 7.
- the right-hand dashed curve 28 in FIG. 4 corresponds to the right-hand area in FIG. 3, in which the carrier tape 23 is again in the sewer pipe 4 after it has passed through the branch pipe 7.
- the part of the carrier tape 23 which is guided along the circumference along the inner wall of the branch pipe 4 is shown in solid lines in FIG. 4.
- a branch box 29 is provided in the branch pipe 7 and attached to the inner wall of the branch pipe 7.
- the installation object 2 can be guided past a branch 25 to the right or left of the branch pipe 7. This is shown in broken lines in FIG. 4.
- the carrier tape 23 or laying object 2 guided in this way is thus fastened to the sewer pipe 4 outside the region of the junction parts 26. With all installations, care should be taken that the installation object 2 is not kinked.
- the inliner 14 loaded with a pressure medium (not shown in detail) abuts against the spacer of the assembly carriage 11, so that the latter moves continuously or in sections in the working direction A.
- the carrier tape 23 or the at least one line and / or the empty pipe 2 is gradually passed through the central passage 13 of the assembly carriage 11 via the gooseneck-shaped, rotatable guide element 6 of the guide device 5 to the radially outer region of the sewer pipe 4, i.e. in the area of
- the guide element 6 is controlled in a targeted manner in the region of the junction parts 26 such that the carrier tape or the laying object 2 is preferably guided around the branch 25 as shown in FIG. 4. To avoid the permissible bending radius _ .., V J £ ,
- the gooseneck-shaped guide element 6 is pivoted in the direction of the double arrow D, wherein the guide element 6 can have a U-profile which is not shown in FIG. 1 and is open radially outwards for better guidance of the carrier tape or installation object.
- the carrier tape or installation object is therefore not under any operating conditions within the cross section of the branch pipe and is thus securely fastened to the inner wall of the sewer pipe or to the inner wall of the branch pipe.
- the carrier tape 23 or installation object 2 can also be installed at a different location than in the region of the upper apex of the sewer pipe 4. Such an attachment is also easily possible by means of the adjustable guide device 5.
- Inliners 14 for sewer pipes in particular for sewers, have a diameter of between 100 and 1500 mm, for example.
- the standard length of such an inliner is around 200 - 400 m.
- the spacer 20 serves to avoid direct contact between the inliner 14 and the guide device 5. If the assembly carriage 11 is not moved by means of an inliner 14, the spacer 20 can also be omitted.
- a distance setting is preferably carried out by means of a suitable control device 32, which comprises, for example, a sensor 32 '.
- the carrier tape 23 is held vertically upwards by means of the gooseneck-shaped guide element 6 of the guide device 5, so that it can be securely attached to the inner wall 3 of the sewer pipe 4 in the dry zone.
- Carrier tape 23 is then guided so that it is not pressed by the inliner 14 into the free cross section of the branch pipe in question.
- the gooseneck-shaped guide element 6 will make a small swivel.
- the laying and fastening of the laying object 2 makes it possible to control the angle of rotation of the guide element 6 during the laying such that the laying object 2 is guided past the branch pipes. This can be done, for example, at the push of a button via a remote control, by entering exactly how many degrees the guide element 5 has to turn. It is also possible to lay the installation object 2 laterally, for example at the level of the lateral bulge of the sewer pipe or below in the sewer pipe. Furthermore, part of the assembly carriage 11 together with the guide device 5 can also be designed to be rotatable, e.g. in that an inner part or head of the assembly carriage can be rotated so that the carrier tape can also be laid down in the sewer pipe.
- this rotation takes place simultaneously with the computer registered in the land registry plan, so that it will be determined at a later point in time exactly where the carrier tape is located in the main channel. If a sewage connection for an additional house is then to be installed at a later time, the sewer is not milled exactly at the point where the carrier tape was previously laid. This largely prevents the carrier tape from being destroyed by sewer work.
- the carrier tape is also suitable, for example, for holding fiber optic cables.
- a so-called robot vehicle known from the prior art can also be used as the assembly carriage, this being provided with the guide device according to the invention instead of the conventional working head.
