Description

Test area

The invention relates to a process for the installation of at least one conduit and / or one pipe in installed, inlet or waste medium-serving pipes, in particular in sewer pipe systems or sewers and the like, wherein the new laid conduits and / or empty pipes are introduced into the pipe and they are attached to its wall.

BACKGROUND OF THE INVENTION

The area of communication shows consistently high incremental rates, and the end of this increment cannot yet be seen. Even though telecommunications are developing largely through satellites, the transmission of data and information over cables stored in the ground has kept at least equivalent to satellite transmissions. In addition, cables and cables laid in the ground are becoming increasingly important with the introduction of glass fiber cables, which allow large amounts of data to be transmitted at high speeds.

Particularly with respect to fiberglass cables, it is desirable to provide a fast and cost-effective solution for the construction of overlapping communication networks. Such laying of cables or ducts, of course, requires costly earthwork unless we use the already existing empty pipes or other usable drainage pipelines.

One method of installing conduits and / or empty pipes, whereby conduits such as information transmission lines, such as currently practiced, can be passed into such empty pipes later, such that they are routed to existing sewer lines, e.g. sewage pipes, which may have a very richly dimensioned diameter, are mounted on the walls of such newly installed conduits or empty pipes, for example by using pipe or cable clips and clips anchored to the duct walls at regular intervals. Such a method of installation is obviously very laborious and costly, and can only be carried out on large-scale sewer lines accessible to the human figure, unless the installation work is not carried out by cameras guided and monitored by robots, thus allowing empty pipes and cable in wbavtt i oro channels unrestrained.

By means of anchoring clips which are fixed around the circumference of the entire cross-section of the cannula, it is possible to attach 1 more empty pipes or lines. Such anchorage clips can be deposited by robots I in existing sewer lines, such as waste water pipes with a smaller clear cross-section, which however must be sufficient for at least such robots, such pipe cross-sections must therefore be about 200 mm and above. It will be appreciated that such additionally installed pipes and cables, whether already fastened with pipe clips or cable anchors, are exposed to a harsh canal operating environment. These pipelines must be able to withstand the onslaught of wastewater at high water inflow, as well as high-pressure canal cleaning. Particularly on the finer clamps and sleeves, solid particles from the wastewater are deposited and settled, as experience shows, and they sooner or later will clog the channel, so it has to be assumed that even these fasteners of additionally installed lines and empty pipes will not be able to withstand such incursions. For this reason, it cannot be foreseen in the future that such procedures could be permanently applied in view of expected disturbances.

In addition, the normal operation of the duct itself is also made more difficult. Such ducts then closed the sky and pressure tested using inflatable sealing bags.

According to DE-U1 298 01 424, flat hollow profiles in the form of a cable duct made of metal or plastic, which are either glued to the inner wall of the canoid or fixedly anchored to its wall, are used for laying cables in a non-human sewage pipe. For this laying procedure, robots entering such pipeline routes are used in impassable gas, water or sewage channels.

The disadvantage of such robotized systems is that the channel must be remedied beforehand. If the lines were to be hung by robots without prior sanitation of the channel, then it is necessary in the future to take into account that such lines will have to be covered later by the lining, which is not usually possible to do professionally. This would entail not insignificant additional workflows associated with extra costs,

There are naturally known methods for the rehabilitation of channels, in which shape-stable sections are inserted into the old damaged channel and interconnected. The space between the newly drawn pipe and the old pipe can be filled with a suitable filler material, called "Pmermer" in such measures. In order to set up dimensionally stable liner pipes such as supplied by Hobas Rohre AG from Switzerland, a new pipe was also proposed. the old sewer pipe was inserted by conduits or empty pipes. It is obvious that such a solution is in principle costly and, if it is to be laid lines or empty pipes, for example for telecommunications, this is always associated with the foundation of such form-stable pipe liners made of plastic or steel.

- 3 The laying of additional lines or empty pipes is where the lining system was installed, i.e. where the inner lining of the old route was carried out, and the lining associated with the further lining of this lining. Where canals require remediation and have not yet been remediated, this does not matter, and even economically beneficial. Where these additional lines are to be installed in intact or even new laid channels which do not require remediation themselves, this means, however, accompanying remediation and damping associated with the work and cost.

SUMMARY OF THE INVENTION It is an object of the present invention to avoid the above-mentioned disadvantages of the prior art and to provide a process allowing additional and additional laying of pipes and / or empty pipes to existing routes in a competitive manner compared to traditional excavation laying. protected, it is possible to carry out professional rehabilitation before and after, but not necessarily, without limiting the operation of the channel. In addition, provision should also be made for the subsequent remediation of the liner to be removed, whereby these lines and / or channels can remain in place.

The object of the present invention is to provide a tubular or tubular inner liner for insertion and / or insertion into the pipe to be installed, wherein at least one (or more) flexible tube and / or guide is provided in the region of its outer surface. SUMMARY OF THE INVENTION The present invention is characterized in that a tubular inner liner is inserted or inserted into the existing already installed sewer pipes, in sewer pipe systems or networks, and the like, for example in ventilation pipes and between the outer wall of the inner liner and the inner wall existing! new ducts or empty pipes have been provided in the channel walls, in which later further ducts are introduced. Due to such a solution, no additional suspension or anchoring elements are required by which individual newly laid lines and / or empty pipes are fixed or held in the duct pipe. In addition, a new smooth lining of the pipe is led through the tubular inner lining, which leads the waste water so that no disturbing spots will occur, affecting the flow or flow in the duct pipe, or where due to settling solids entrained with the waste water create sources of clogging of the channel brightness. On the contrary, such a smooth inner surface of the new tubular lining could favorably influence the hydrodynamics of the pipeline. All newly laid empty pipes and ducts are separated from the medium flowing inside the duct and there is no risk of corrosion and abrasion for the newly installed ducts. channel routes. Obviously, this procedure creates practically unlimited possibilities of building a data communication system with relatively low construction costs, because virtually all households and other industrial

There may be situations in which existing conduits, sewage systems or networks already exist such that the tubular inner liner can only be drawn in when its outer diameter is substantially smaller than the inner diameter of the sewer pipe into which the tubular inner liner is to be inserted. or draw in. In particular, an irreversibly deformable hose with an outside diameter that can be easily drawn into the sewer pipe is drawn as a tubular inner lining. Then the hose is shaped by suitable action, such as high internal pressure, and in this way is pressed against the inner wall of the sewer pipe, so that said empty pipe guides C 1 are irreversibly clamped between the formed liner hose and the inner wall of the channel.

In such a formable hose, a flexible hose is preferably used which, in addition, can be folded in terms of its cross-sectional dimensions such that a flat track is formed which can be simply drawn into an existing duct or sewage system C1 network. Together with the insertion of such a hose, it is possible to place the necessary empty tubes and ducts on the outer surface. After the hose has been drawn into the duct, the hose is then closed at its ends and filled by liquid or gaseous media as compressed air is pressed against the inner wall of the duct and then firmly irreversibly solidified, for example by heat or ultraviolet radiation. , depending on whether the hose material is heat or UV curable. The pressure can be released from the interior after extraction. The hose remains pressed tightly against the inner wall of the duct and will hold the conduits and the empty tubes at the point of the tube.

In principle, the installed lines and / or empty tubes (for later insertion of the lines) can be installed at all points of the tubular lining and thus at all points of the existing duct. Preferably, however, such empty tubes and / or conduits are located on the upper portion of the outer surface of the tubular liner, so that when the tubular liner is installed, they will not always be located on the upper side of the channel tube. To facilitate the installation work at the site, i.e. on the construction site, it may be advantageous to use a tubular inner liner that has already integrated empty pipes and / or guides in its wall. With this in mind, the inner liner hose Jeko, such lines and empty tubes can be integrated into its wall.

However, it may also suffice to spot-mount the empty tubes and / or guides on the outside of the tubular linings being retracted or retracted along their length so that they then dowel the tubular liner installation firmly attached thereto. Such anchoring can be carried out by simple means on-site and at the time of installation tubular internal • 99999 · • 9 9 9 9 9

5 linings, so that the individual pipes to be applied or guided can be attached to the tubular liner directly during its drawing into the duct.

When a hose is drawn into the duct, it is to be a fabric-reinforced hose for strength reasons, and a fiberglass-reinforced hose is to be preferred. Furthermore, a textile fabric or reinforced hose impregnable with a curing resin may be used as a hose. For this purpose, resins which are cured by ultraviolet radiation or heat can be used as a resin to strengthen the hose, which is pressed against the inner wall of the duct by internal pressure. Since such resin is strongly tacky in the uncured state, a plastic foil hose must be threaded onto the outer and / or inner surface of such a hose so that the hose walls, especially when the hose is introduced into the duct in a folded state, do not stick together.

Especially in the case where a tubing is used as a tubular inner lining, which as such is stable in shape, i.e. in the form of a hose. it is advantageous to retract the tubular inner lining of the saws into the channel pipe with the dimensional stability spirally of the web material after being drawn into its definite shape and not consolidated therein. For this purpose, a suitable machine assembly is provided in one access shaft and the sheet material is fed to the machine as an endless belt. In the machine, this endless belt is spirally rolled up and adjacent to each other longitudinally! the edges of the material in this coiled state are joined to each other in a suitable manner, for example by sealing or welding. The spiral tube is then continuously inserted into the duct, while at the same time a guide tube or empty tube is placed on the outer wall. The strip material used in this case to form the spiral coiled tube may be a metal or plastic strip.

A further possibility, which may already be preferred in certain circumstances, is one in which a plastic tube is used as the tubular inner lining, the cross-section of the tubular wall into which the tubular wall loses itself. It draws the ducts in the form of a flatly folded profile, and then, by means of the heated medium, it is re-formed into its original shape by internal pressure.

In order to achieve a tight fit of the tubular liner forming the tubular inner liner to the inner wall of the duct, it may be advantageous to use a plastic tube as the tubular liner, the tube cross section of which is mechanically extruded before being drawn into the existing tubular tube. and, after being drawn in, the tensile stress is allowed to expand to the original dimension of the pipe diameter. By this measure it is achieved that the tubular inner lining abuts the inner wall of the duct and that a tight fit of the empty tubes and / or ducts drawn in between the outer wall of the plastic tube and the inner wall of the existing duct is ensured.

The retrofitting of conduits and / or empty pipes to existing sewer pipes, sewer pipe systems, sewage networks, etc. is preferably performed from access shafts or other easily accessible locations. In place of these Installation approaches It is possible to conduct and / or e φ · · · φ φ φ φ φ φ φ φ φ · · · φ φ φ φ φ φ φ φ

- connect the 6 empty tubes, inserted between the tubular liner and the existing conduit pipe, to their ends in the switchboard and / or busbar, to be later connected or connected to the existing communication network or to the electrical network inside these distribution blocks; the same applies to empty pipes, in which cables, such as data communication lines, can later be pulled in with the access blocks.

The assembly material used to impregnate the ducts and / or the empty pipes, and which glue together the individual ducts and / or the empty pipes and attaches them to the pipe wall, also constitutes a versatile protection. This is especially true when the conduits and / or empty tubes are completely embedded in the assembly material when they are practically potted.

In a further preferred embodiment, the laid lines and / or empty pipes are impregnated with the adhesive having a tacky effect, then introduced into the pipe with a mounting hose serving as a hose liner, the mounting hose is then expanded and the guide and / or empty pipes thereby. press the pipe against the wall and then up to a sufficient otter to allow the pipes and / or empty pipes to be attached to the wall, the pressure on the assembly hose is released. A particular advantage of this process is that only a single assembly hose is used, which after removal of the conduit or empty pipes in the previously installed pipe is removed and can be reused, so that only existing pipes remain in the existing pipe, e.g. empty pipes or lines. This procedure also provides the possibility of simultaneously installing the ducts and / or empty pipes side by side at specified distances apart and in a very diverse arrangement.

The assembly hose used is preferably removed from the pipe after assembly; if such an assembly hose of suitable material is used, the hose may be used multiple times to install such conduits or empty pipes in existing water lines or waste water channels.

The mounting position of these additionally laid ducts or empty pipes on the inner wall of the duct can be determined in advance; for this purpose, these lines are then placed appropriately on the assembly hose. However, the mounting position is mostly selected in the upper semicircle respectively. on the upper circular arc of the cross-section of the duct into which the ducts and the empty pipes are deposited.

Preferably, the ducts or empty tubes to be laid are laid over their entire length into a tacky adhesive, i.e. a correspondingly suitable adhesive paste, with which they can then be pressed against the damp inner wall of the channel pipe and adhered thereto. In such an epoxy resin, the clay may be a two-component epoxy resin which can be cured by the passage of time or to drink additional heat or radiation of a suitable wavelength.

As a carrier material for the assembly material or the substrate. mineral and / or synthetic fillers can be added to the adhesive material, for example in the form of a fabric, knitted fabric, laminate or plunger. The appropriate material is chosen with regard to the requirements.

Obviously, after bonding and curing, the additional ducts will be rigidly connected to the inner wall of the duct and will preferably grow into the assembly material and any filler material added, such that the ducts and / or empty tubes are combined with the assembly material in one mass. Against the inner space of the duct respectively. Waste water, if these pipes are sewage, these lines are covered and protected by a specified layer of this material. This material overlaps the conduit with smooth transitions to the conduit and connects it to the inner wall of the conduit by a positive fit. Alternatively, the outer cover layer, which is deposited in the form of an endless strip material, i.e. the lacquer strip material is first applied to the assembly hose, the empty tubes and guides laid on the strip material and embedded in the mass. This cover layer can also be firmly connected to the carrier material on one side and remains in the channel after gluing the empty tubes.

If the adhesive and carrier material used exhibits static strength material properties, it is even possible to additionally increase the static load-bearing capacity of the duct into which empty tubes or ducts are inserted using this method.

It is recommended to use a flat hose that fits into the pipe as a mounting hose. Such a flat hose may be considered to be flattened on a flat strip prior to introduction into the duct so that empty tubes or ducts can be placed on its upper side. And such hoses are then inflated with a suitable liquid, liquid or gaseous after being drawn into the nanal, so that preferably the homepositioned conduits and the empty tubes embedded in the material exhibiting adhesive properties are pressed against the inner wall of the channel. A gaseous or also a liquid medium can be used to inflate the hose, and in most cases a gaseous medium, such as air, is preferred. To inflate the hose, one end of the hose can be closed, unless inflation is from both sides.

In order to ensure optimum mounting mass pressure along with conduits or empty pipes, the flat hose should be circumferentially selected with respect to the pipe duct and be suitably extensible to accommodate the conditions inside the pipe. Preference is also given to hoses made of rubber or silicone and in themselves characterized by good separation from the assembly material.

In order to achieve optimum deflection of the assembly hose from the assembly material to its curing in the channel, anti-adhesive layers may also be inserted between the assembly hose and the assembly material, characterized by high tackiness or adhesive and / or carrier material, for example in the form of anti-adhesive separation paste. in the form of a strip material, for example of plastic foil.

Especially when the pipes and / or empty pipes to be laid are to be placed on the sides of the channel cross-section, it may be useful to attach this anti-adhesive layer to the mounting hose, with a dry-tape as a preferred option. This antiadhesive layer is then coated • · ····

The material with empty pipes and / or guides, so that they can then be brought into the correct position with respect to the channel cross-section.

A further possibility is to adhere the non-adhesive layer, for example in the form of a plastic foil, by bonding it to the outer carrier materials or to the substrate. with fillers which, after sealing the conduits and / or empty pipes, will remain firmly adhering to the channel wall when the assembly hose is pulled out.

There is also the possibility of attaching the non-adhesive layer in the form of a strip material by means of double-sided adhesive tape to the assembly hose. Such a tape can then be removed from the pipe after the assembly hose has been removed from the pipe.

DETAILED DESCRIPTION OF THE INVENTION

In order to install the guides and / or empty pipes in the existing state! As indicated in FIG. 2, the folded hose 4 is withdrawn from the container spool 4 at its cross section and is lowered via an insertion drum 4 into the access handling shaft 4, as is shown in FIG. vertically between the surface of the street / and the pipe 1, respectively. In this hose 3, the clay may be a cloth and / or layered hose impregnated with the resin, so that the hose 6 and the hose 7, respectively. the flattened strip allows easy handling because it is flexible. During the insertion of this hose 3, the supply drum 11 is removed. Directly from the supply on the delivery truck 2, they unwind the conduits or flexible empty tubes, run through the bending roller Ifi and duct together with the flattened hose. At the location of the insertion drum 4, these lines and / or empty tubes 2 can be attached to the upper surface of the flattened hose 3 so that the lines / empty tubes 2 cannot slip. The hose 4, together with the conduits / hollow tubes 2, are drawn into the duct 1 from the well 6 from which the duct 1 is easily accessible, for example by means of a pulling cable extending in the direction of arrow 12. The hose 3 is then ducted into the duct until further. 2 of an access point (not shown), for example to another shaft, so that the end is then accessible there. The hose 3 with the conduits / empty tubes 2 on its upper side then lies at the bottom of the conduit 1, as shown by the broken line 16 in FIG. as shown in a cross-sectional view of the ducts of Figure 1A. Then the hose 3 is cut off from the supply drum 4 and sealed at both open ends. Compressed air is then supplied from at least one of these closed ends from a compressor, for example installed on a lorry 2, the hose 6 is inflated and thereby pumped to the inner wall of the duct 11 to press the lead / empty tube 2 to the upper side of the duct. Thus, the conduit / empty tube 2 abuts the homf side of the conduit 1, as shown in Figure 1B. Depending on the type of hose used, this hose then becomes constricted in the inner wall of the duct 1 pressed against the position of the hose. for example, if the hose 6 is one that is impregnated with a thermosetting resin, the inside of the hose 6 is heated to cure the resin, or if the hose is impregnated with a UV-cured resin, the inside of the hose 6 is irradiated with a suitable source After the hose 6 has cured, the internal overpressure can be discharged. The conduits and / or the empty tubes 2 are then led to a transmission station 14, located with good accessibility on the wall of the shaft 6 and fixed. The ends of the hose 4 can then be suitably fastened at the point of entry of the duct 1 into the shaft 6 so that the space between the duct wall 1 and the outer wall of the hose 3 is sealed. The cannula 1, as shown in Figure 1B, is provided with a smooth inner lining while simultaneously protecting and sealing the conduits or the empty tubes 2 adjacent the inner wall of the cannon tube 1. In the empty tubes 2 installed between the channel tube 1 and the hose 6, it is possible later to draw the necessary lines, for example data communication cables in the form of fiber optic cables, away from the transmission station 14,

As can be seen from Figures 1 and 2, this method of retrofitting conduits and / or empty pipes into existing ducts, sewage piping systems or SFTIs is a highly adaptable and universally applicable process to construct communication sll using existing sewage piping systems.

While the method of installing conduits and / or empty pipes 2 into existing sewer pipe systems using a 1m flexible flexible flat folded hose 3 has been described above, Figure 3A shows a cross-sectional view of a duct 1 showing a longitudinally folded tubular profile of the plastic tube, which is folded inwards with its edges - in a sectional view, which means that both edges are folded downwards under the tube and facing towards each other. The tube formed in this way, for example of plastic material, exhibits a certain dimensional stability even in the folded state, as shown in Figure 3A. On the upper side of this composite hose 2, the guided tubes 2 are again arranged and attached so that they are inverted in the shift of the upper lining of the channel pipe. When the hose is then positioned appropriately in the duct 1, the hose is shaped by means of heated handles and again under internal overpressure back to the original tube cross section, so that it inserts the inner side of the duct 1 and at the same time of the pipe 1 as shown in Figure 3B. While the above method of using a hose as a tubular inner lining has been described, Figure 4A shows a schematic view of a duct 1 extending between two shafts. In contrast to the methods described above, in the drawing of Figure 4A, the individual sections of the pipe 16 are lowered into the duct 3, which are inserted in sections by means of the displacement device 17 into the duct pipe 1. The individual sections of the pipe 16 slide into each other. or screw together so that they are then connected together. At the same time, the conduits / empty tubes 2 settle on the upper side of these pipe sections 16 and move together with the pipe sections 16 together. These lines respectively. the empty tubes can be directly extended from the feeder vehicle as shown in Figure 2. Then, when the pipe sections 16 penetrate to the second shaft 3, the conduits / empty pipes are also introduced therein into the transfer station 14 and fixed therein. The required conduit / empty tube length may be lowered into the duct as soon as the first pipe section 16 is introduced, or the conduit or empty tube may be coated towards the transfer station 14. If desired, it may be possible to the possibly remaining intermediate space or an annulus to press the baffle material 15 as shown in Figure 4B.

Figure 5 shows a schematic construction of the field using the methods described above. For example, in order to build a new information transmission network, the existing installed main sewerage systems 1 of the sewerage network, for example, are used advantageously for the purpose of installing a large number of individual lines / empty pipes 2 between them. «• a a a a a a a a a a a a a a a a a a a a a a

11 by transmission stations 14 using a tubular inner lining, for example a hose 6 or folding from the pipe sections 6, as described in the latter example. Through the existing house connections, ie the house outlet of the sewer pipes which drain the waste water from the house 12 into the sewer pipe 1, also with the identification mark 1, the tubing of the inner tube lining is preferably pulled. In house 12, a transmission station 14 is then set up to connect this household to the newly installed network. At the point of transition from the conduit of the house connection 1 to the main (collecting) conduit 1, a separate connection station 12 can be provided to carry out the necessary conduits / empty pipes 2 ^{to the} house 12 according to the second embodiment as shown in Figure 2. to retrofit the ducts and / or empty pipes in the existing duct 1, for example in a ground water pipe, again at the manhole, extending vertically between the street surface 107 and the duct 121, the container 104 is flat. folded assembly hose IQ5. In addition, a storage drum 106 is placed on the handling shaft 103, on which the laying lines or windings to be laid are wound. empty tubes 122 These reservoir drums 106 can, for example, be supplied on a truck 108. The truck 108 runs a guide or a machine. the empty tubes 102 over the transfer roller 109 at the rear of the truck 108 vertically down into the handling shaft 123. Under the transfer roller 109, on the platform 100, there is a container 111 containing a mass 112, characterized by tackiness. Around the middle of the container 111, there is further provided a spreading device 113 with two guide and spreading rollers 114 between which a running guide / empty tube extends over the transfer roller 2. After rolling the pipes / empty tubes 102, these are then saturated with assembly material on the applicator 113 and on the guide and applicator rollers 114 on all sides, i.e. on both sides.

The mounting material 112 is preferably a bicloidal epoxy resin.

The saturated conduits / empty tubes 102 thus extend below the platform 100 from the platform 100 and meet the assembly hose 105 and are stored on the homf side thereof. For this purpose, the assembly hose 105 is guided from the multi-drum 104 via a first transfer shaft 115 and a second transmission pulley H2 located at the edge of the handling shaft 103, and this second transmission pulley 116 ensures that the assembly hose 105 lies at the point of contact with impregnated by running / empty pipes 2 flat as a lying strip.

The mounting hose 105 may be a silicone or rubber hose.

The assembly hose 105 with conduit 112 and / or empty tubes 122 saturated with assembly mass 112 and not placed therein is then introduced into the conduit 121 at the end of the handling shaft 103, during which the assembly of the hose 105 is coated in the direction of arrow HZ. To this end, a tow rope (not shown) can be attached to the (not shown) end of the mounting hose 105 (for more details see the description below). Β ······· · · ··

- a drawbar (not shown) that pulls the assembly hose 105 towards another ducting shaft 103 connected to the conduit.

As can be seen from Figure 6, two containers US of the carrier tape US, for example in the form of a fabric tape, can be additionally stored in the mounting material container 112, which are saturated with the mounting material 112 and then guided over the application and guide rollers 114. side to the laid pipes / empty pipes 102.

After insertion of the assembly hose 5 with guided / empty pipes 102 laid on its upper side or possibly with additional carrier straps 119 into the duct pipe 101, the hose is closed at the not shown end at the next, also not shown, manhole shaft 103 and at the manhole shaft 103 shown in Figure 6 is separated from the feed container drum 104. Then, the pumping means mounted on the truck 108 are connected to the interior of the assembly hose 105 and the assembly hose is inflated with a pressure medium, preferably air. An assembly hose assembly 5 with conduits / empty tubes 102 and both carrier strips US loaded onto the conduit 101 is drawn into the conduit 101. On the one hand between the assembly hose 105 and the conduits / empty tubes 102 and on top of the conduits / empty tubes 102 is shown in Figure 7A. . Starting from this position of Figure 7A, air is introduced into the interior of the mounting hose 105 by means of a pumping device so that the mounting hose 105 is inflated as shown in Figure 7B. As a result of the inflation hose 105 being inflated, the conduits / empty tubes 102 are compressed into the assembly mass by pressure and encircled by the carrier strips US. to the top of the duct 101.

The assembly hose 105 is then held in the inflated condition as shown in Figure 7B until the assembly mass 112 is cured and the conduit / tubing 102 is glued to each other and to the wall of the conduit in the upper semicircle of the cross-section of the conduit. 121- To cure the mounting mass 12, heat radiation or other radiation may be applied depending on the type of mounting mass.

After sufficient stamina, guaranteeing! to fully cure the assembly mass 112, the pressure is released from the interior of the assembly hose 105. As a result of the elastic contraction, the assembly hose 105 is peeled away from the assembly pit 112 so that it can be pulled out again from the duct 101 and out of the handling shaft 103. The conduits / empty tubes then remain as shown schematically in Figure 7C. It will be appreciated that the conduits / empty tubes 102 are squeezed into the carrier material 102 and overlapped by the outer carrier channel 101 facing the inner space of the duct 101 with the inverted carrier tape 119.

The mounting position of the ducts / empty tubes 102 at the inner wall of the duct can be predetermined, but is usually stored in the upper semicircle of the duct cross-section.

The assembly and the mass, preferably a two-seam epoxy resin, can also be cold-cured.

- 13 However, the curing process can be accelerated by additional heat support, ie the curing time can be shortened. This can be accomplished by heating water, air or a pen to inflate the mounting hose 105.

In addition, mineral or textile layers and laminated and / or woven materials may be used as carrier material for the adhesive component of the mass.
