Description

Be used at least one cable and/or hollow pipe are installed on the supply of having laid or discharge line, especially are installed to the method for buried pipe system or pipe network and analog

The present invention relates to a kind of installation method, be used at least one cable and/or hollow pipe are installed in the pipeline that is used as service or discharge tube that has laid, especially be installed in buried pipe system or grid and the similar object.Cable wherein to be laid and/or hollow pipe are presented to pipe interior and are fixed in Qi Bishang.

Communication field demonstrates lasting high growth rate, and its end is also can't see in this growth so far.When particularly centering on the satellite development aspect the territory communication of long-range, big face, data and information by cable underground is transmitted have kept equal importance at least with this mode of transmitting via satellite.In addition, be positioned at the use of underground cable and cable, seem more and more important again along with glass fiber cables.Because this cable can at full speed transmit lot of data.

Especially utilize glass fiber cables, people expect rapidly fast, set up low cost the extensive communication network of coverage rate.The laying of this cable or lead needs a large amount of earth works naturally, has only had mounted hollow pipe or other underground piping to utilize.

With cable and/or hollow pipe install a kind of now practicability method, wherein can be with the information conveyance cable of cable-for example-draw in this hollow pipe, be in existing buried pipe, for example in the drainage pipe that may have very big cross section, on underground tube wall, hammer into staple with fixing spacing by means of cable clamp or pipe clamp, thereby cable that will newly be mounted or hollow pipe are fixed on the wall.This mode is that labour intensity is very high, expense is also very high naturally, and only can be very big at cross section thereby buried pipe that the staff can enter in just can carry out.Only use to have that video camera leads and the robot that monitors carries out this installment work, like that, need not to be under the situation about can be maked an inspection tour, also cable or hollow pipe can be installed at buried pipe.

Also many hollow pipes or cable can be fixed by means of the tensioning snap ring, the latter is tauted on the whole circumference of channel cross-section.Such tensioning snap ring also can be laid by means of robot, the place of installing also comprises the existing buried pipe with smaller cross-sectional area, drainage pipe for example, but this cross section is still enough big for these robots, promptly the diameter of these pipes must be not less than 200mm.This shows that this hollow pipe and the cable of installing afterwards no matter be to utilize pipe clamp or cable clamp, perhaps utilizes above-mentioned tensioning snap ring to fix, and all will stand the test of abominable pipeline service conditions.Waste water stream when such pipe line must bear high discharge washes away and high pressure--and passage cleans.Particularly, rule of thumb want the solid matter in the settled wastewater, thereby want early or late passage at wire card and tightening hoop place.Thereby must consider that these retaining elements of cable of An Zhuaning or hollow pipe possibly can't sustain consequent blockage pressure afterwards.For this cause, if consider the contingent disturbing factor of expectation, the possibility that this method can access enforcement future is little.

In addition, the difficulty of normal passage operation strengthens.Corresponding passage can not seal or carry out pressure check again with the air blast shutoff.

According to DE-U1 298 01 424,, used smooth hollow profile in order to settle cable in the waste pipe that can not make an inspection tour at one, as a cable channel shape, it is made by metal or plastics, perhaps is fixed to be pasted on the inwall of buried pipe, and perhaps staple thereon.For this instrumentation, in the gas pipeline that can not make an inspection tour, water pipe and waste pipe, people need use robot to enter in the corresponding pipeline.

The weak point of this robot system is that passage must be rebuild before this.If passage is not rebuild before this, after robot has hung up properly cable, also need subsequently cable is hidden with covering in the pipe, and this is impossible in most cases technically.And this be crucial, additionally increase the processing step of cost.

The passage repair method has also been arranged, the pipeline section of dimensionally stable of wherein in an old or damaged pipeline, packing into, and be joined to one another.In this measure, the interval between pipe of newly packing into and the old pipe can utilize suitable perfusion material, and promptly a kind of so-called " plugging agent " squeezes and fill in.In the method for this pipe of straightening again of inserting fixed in shape, for example propose by the Hobas Rohre AG company of Switzerland, also advise inserting cable or hollow pipe in the space between new pipe and old buried pipe.This shows, very complicated on this methodological principle, and settle cable or the hollow pipe that is used for telecommunication if desired, always need connect together with installation pipe cover element these dimensionally stables, that make by metal or plastics.

A gut line has been installed, has been that is to say, when the covering of an inside had been arranged, additional cable or hollow pipe were always laid and are interrelated with the trimming of further interior lines.Where passage need be rebuild but also rebuild, and is inessential, even also brings the advantage of economic aspect.

But, this means that when settling this extra cable in the passage that promptly need not to rebuild, relevant trimming causes extra work and extra-pay if in the intact or even brand-new passage of laying.

The objective of the invention is, avoid the above-mentioned shortcoming that exists in the prior art, and a kind of method is provided.Utilize it can in existing passage, additionally lay or settle afterwards cable and/or hollow pipe, and have direct competitiveness with respect to the traditional formula that excavates construction method.Wherein can provide reliable protection for cable and the pipe of settling afterwards, as required can be before or carry out technical feasible trimming subsequently, but be not the task of belonging to essential, and the not operation of limiting channel.In addition, can also cancel follow-up interior lines trimming, wherein, cable in the passage and/or hollow pipe can remain unchanged.

Realize this purpose, rely on a kind of method that begins to mention type.Being characterized as of it pushes the liner of a tubulose or hose-like and/or be pulled in the pipe of having laid, wherein, is mounted with blank pipe and/or cable of a flexibility at least in its outer surface region.

The preferred embodiments of the present invention are provided by dependent claims.

Basic imagination of the present invention is, at existing, buried pipe, underground piping system or the network and the analog that lay, also comprise in the air pipe, advance or draw in the liner of a tubulose, and between the inwall of the outer wall of this liner and existing buried pipe, settle new cable or hollow pipe, so that pack cable subsequently more therein into.Utilize this mode, need not to use extra hanging element or fixed component, just cable and/or hollow pipe single, that will newly lay can be fixed and remained in the buried pipe.In addition, utilize tubular liner to obtain a new level and smooth tube wall, waste water passes it and flows, thereby can not form and stop that it flows through the interference place of buried pipe, perhaps in these zones, forms obstruction because of deposition takes place solid matter entrained in the waste water.On the contrary, the smooth interior surface of so new tubular liner also can promote liquid fluidity.The hollow pipe of all new layings and cable and in buried pipe flowing liquid separate, do not have the corrosion relevant or the danger of wearing and tearing with the new cable of settling.Simultaneously, utilize this method can also make existing buried pipe obtain extra sealing or trimming.Can see, by this method, in fact can obtain unlimited multiple possibility, set up or the enlarging data transmission network with quite simple structure, this be since in the reality facility of all family or other industry and community all link to each other and follow with the waste water underground piping, the latter can access utilization, even those have the buried pipe of relatively little diameter, for example the buried pipe diameter is between 80 to 150mm.This is owing to also can use method of the present invention in these buried pipes.

Following situation may appear, existing mounted buried pipe, buried pipe system or network, if make and to want tubular liner is drawn in, its external diameter must will push or draw in tubular liner less than the internal diameter of buried pipe in this underground piping.Particularly below in the situation, as tubular liner be the flexible pipe of an irreversible transformation, its external diameter should make it be drawn in the buried pipe at an easy rate and go.Next, this flexible pipe passes through adequate measures, as is subjected to a high internal pressure effect, deform, and press to the inwall of buried pipe here, thereby between flexible pipe after the distortion and underground tube wall, cable and/or hollow pipe is squeezed and can not moves.

As such flexible hoses, preferentially select flexible flexible pipe for use.In addition, its cross section should be folded up, thereby forms a flat band.Can simply it be drawn in existing buried pipe or buried pipe system or the network and go.By drawing in this flexible pipe, can simultaneously necessary cable and hollow pipe be placed on its outer surface.When flexible pipe be pulled into go in the underground piping after, hose end can be sealed, and by filling liquid medium or gas medium,, its inwall that is pressed onto buried pipe be got on as compressed air.Hardenable or be subjected to ultraviolet ray-radiation-cured material when if the manufactured materials of flexible pipe is a kind of being heated, then make flexible pipe nestle against the irreversibly fixing sclerosis of inwall by heating or ultraviolet radiation.After flexible pipe is fixed sclerosis, just can get rid of the pressure that in the flexible pipe inner space, acts on.Then, flexible pipe just clings on the inwall of buried pipe tightly, and cable and hollow pipe are maintained fixed.

In principle, cable and/or the hollow pipe (for cable is introduced) that is placed can be placed on any side of tubular liner, thereby make on its any side that is placed in existing buried pipe.But, these hollow pipes and/or cable preferably are placed in the upper area of the obducent outer surface of tubulose, thereby make them after tubular liner installs, and are positioned at the top of buried pipe.

On-the-spot in order to make, be that installment work on the construction site is carried out easily, the tubular liner of use is if collection dress thereby comprised hollow pipe and/or cable in its wall can be favourable.Because deformable flexible pipe as liner, can be integrated in these cables and hollow pipe in the wall.

For the configuration status that hollow pipe to be mounted and/or cable are maintained fixed with it in the installation process of tubular liner, as long as on the lateral surface of the tubular liner that is drawn into or is pushed into, on lateral surface, fix just enough with point mode them along its length.Such point type is fixing also can directly to utilize simple tools to finish in the installation process of tubular liner at the scene.Thereby single pipe that is mounted or cable can directly be fixed on above it when tubular liner is drawn into as required.

If one bar flexible pipe will be drawn in the buried pipe, from the intensity angle, it should be the weaving flexible pipe, wherein, and the preferred glass fibers flexible pipe.In addition, can be used as also useful hardenable resin impregnation that flexible pipe uses, weave flexible pipe and/or flexible hose.Here can select for use as resin to be subjected to a ultraviolet radiation or to be heated those of sclerosis take place, be pressed against the fixedly sclerosis of flexible pipe on the conduit wall so that make the effect of being stressed.Because resin had viscosity before it hardens, on the outer surface of flexible pipe and/or inner surface, should lay one deck hose-like film, make hose wall be unlikely to adhered to one another to together, particularly when flexible pipe is in folded state and is drawn in the buried pipe.

If employed as the liner of tubulose be dimensionally stable, promptly be not that the effect of being stressed becomes under its net shape and the situation with the material of after-hardening after being drawn into, the liner of tubulose is in being placed into buried pipe the time, be curled into the form of helical form, dimensionally stable by band (Bahnenmaterial), will have peculiar advantage.For this reason, a corresponding mechanical structure is placed in one enters in the vertical shaft, and band is sent in this machine as being with continuously.In this machine, should be with (Bahn) to be curled into helical form subsequently, each vertical limit that longitudinally nestles mutually each other that this is spiral-shaped is connected to each other by suitable method, for example by crimping or welding method.Helix tube constantly is pushed in the buried pipe subsequently, and cable that simultaneously will be to be mounted on its outer wall and/or hollow pipe to be mounted are sent into.In order to form the pipe of helical form structure, it can be a metal tape or a plastic tape that employed band draws material.

Another kind of possibility is, under the condition of determining, the preferred liner that uses a kind of plastic tube as tubulose, its wall cross-section, be drawn in the existing buried pipe with folding profile, and next by means of a kind of heated medium under the effect of internal pressure again distortion become its original tube cross section shape.

In order to make pipe dimensionally stable, that constitute tubular liner rest on tightly on the inwall of buried pipe, following method has advantage, wherein, use plastic tube as tubular liner, its pipe cross section mechanically reduced by the drawing pressing method before it is drawn into existing buried pipe, and after being drawn into, by canceling tensile stress, recover original pipe cross section size again.By such measure, the liner of tubulose is closely nestled on underground tube wall, and thereby the hollow pipe and/or the cable that are drawn between the inwall of the outer wall of plastic tube and existing buried pipe are held closely by putting tube wall.

When being placed in cable and/or hollow pipe in existing buried pipe, buried pipe system, grid or the similar object afterwards, preferentially select so-called passage well or other position that is easy to enter to begin.Be fit in the port area at these, can lead in a distributor disk and/or the connecting box being placed in the cable between tubular liner and the existing buried pipe and/or the end of hollow pipe, so that they can be connected to each other to net afterwards in these connecting boxes, perhaps be connected to an existing communication network and get on, perhaps be connected on the electrical network; For hollow pipe same so, can be by connecting box near hollow pipe, cable, can be drawn in the hollow pipe subsequently as data transfer cable.

Be used for constituting the protection on each face simultaneously with the sticking profit of cable and/or hollow pipe and with cable and/or hollow pipe is bonding to each other and be bonded together employed fabricated material with tube wall.When cable and/or hollow pipe fully are embedded among the fabricated material, promptly be similar under the situation of being got up by cast, all the more so.

In another preferred form of implementation, cable to be laid and/or hollow pipe are used the sticking profit of the fabricated material with viscosity.Subsequently, with a assembled hose they are brought in the pipeline and go as the hose-like liner.Therefore assembled hose is expanded out subsequently, and cable and/or hollow pipe are pressed against tube wall and get on, and through the sufficiently long retention time, thereby cable and/or hollow pipe adhere on the wall, and the pressure that acts on the assembled hose is removed.The special advantage of this method is, only use an assembled hose, after cable or hollow pipe are placed in the pipeline that has laid, this flexible pipe can be removed again, and can be used again, thus stay existing pipeline, as only being cable or the hollow pipe that is placed in the buried pipe.Thereby, utilize this method, can be at the same time, with cable and/or hollow pipe abreast, install, and install with other various modes with the spacing of determining.

Employed assembled hose as already mentioned above, after assembling is finished, is preferably taken out from pipe; Under the situation of using this assembled hose of being made by suitable material, assembled hose can repeatedly be used, and cable or hollow pipe are installed in existing supply or the discharge tube/system.

This installation site that cable or hollow pipe are installed on vias inner walls of carrying out afterwards can pre-determine, and correspondingly positioning instant can on assembled hose with these cables for this reason.But, this rigging position in most cases is positioned at the semicircle district, cross section top or the top circular arc district of the pipeline of settling cable and hollow pipe.

Cable to be mounted or hollow pipe are preferably on its entire length scope and embed fabricated material with viscosity, are in a kind of corresponding suitable binder.Subsequently, they are pressed against on the moist vias inner walls with this binding agent, and can be bonded in the there.A kind of epoxy resin like this can be a kind of two components-epoxy resin, and it can be through certain hour or the heat additionally provide is provided or hardens by the radiation of suitable wavelength.

In addition, the loading material that is used for fabricated material or binding agent can use insert layer mineral matter and/or Composite, for example forms such as yarn fabric, knit goods even felt.As required, use suitable material.

Obviously, after bonding and sclerosis, additional cable and underground tube wall link together securely, and preferably be connected in the fabricated material like this, in case of necessity in additional loading material, make cable and/or hollow pipe and fabricated material formation one.If pipeline is a waste pipe, then with respect to the inner space and the waste water of pipeline, cable is by a definite layer of material covers and protect.This material that envelopes cable has to coincide to the smooth transition of buried pipe and with them and vias inner walls shape and is connected with transmission power ground.In case of necessity, an outer cover can be set also, it is used with ribbon form, and promptly a kind of like this band at first is placed on the assembled hose, among laying the cable that will be placed and hollow pipe on this band and being embedded in material.This cover layer also can externally be fixedlyed connected from a side with loading material, and remains after hollow pipe is bonded in the passage.

If employed binding material and loading material have the static materials characteristic value, even may utilize the method for being given to improve the static bearing capacity of the passage of settling cable or hollow pipe.

As being drawn into the assembled hose of going in the pipeline, should preferentially select flat hose for use.The flat hose here, be meant that it is admitted to before the passage, at first can be stacked into flat band, thereby can place cable or hollow pipe in the above, such flexible pipe utilizes suitable fluid after it is drawn into passage, gaseous state or liquid, expand, be embedded in the material with viscosity and go, be pressed against vias inner walls and get on thereby riding position preferentially is selected in cable above it and hollow pipe.For flexible pipe is expanded, can use a kind of gaseous state or also can be liquid medium.Wherein, in most of the cases, the preferred gas medium is as air.For flexible pipe being blown afloat come, the one end can be closed, unless flexible pipe is blown afloat from two ends.

In order to guarantee that fabricated material and cable or hollow pipe can press together best, the girth of flat hose should be smaller slightly with comparing of buried pipe, and should have expansivity, thereby can mate ducted situation.Also comprise the flexible pipe of being made by rubber or silicone in the preferred row, they itself have good separation property with respect to fabricated material.

For assembled hose after guaranteeing hardened material can be thrown off with this material in passage best, in assembled hose and have between the fabricated material or binding agent and/or loading material of viscosity, also can lay separating layer, as paste separate substance or suitable band, as the separating layer of plastic film form.

If the cable that will install in passage and/or hollow pipe should be placed in the side edge (" arch heap (Kaempfer) ") of channel cross-section, it will be very useful that separating layer is fixed on the assembled hose.For this reason, a kind of preferred possibility is brought realization by a clasp joint connection.On separating layer, lay material and cable and/or hollow pipe then, they can be located exactly with respect to channel cross-section like this.

Another kind of possibility is, the separating layer of separating layer, for example form of film is coupled together with one of external bearer material or insert layer by bonding, and it is retained in the passage to secure adhesion when assembled hose is removed in cable and/or the bonding back of hollow pipe.

Exist such possibility, that is, the separating layer of ribbon form is fixed on the assembled hose by means of the two sides adhesive tape.Such adhesive tape can be got rid of from pipeline when assembled hose is removed or thereafter.

Other details of the present invention and feature are providing in the explanation about embodiment subsequently by means of legend.Legend is depicted as:

The schematic diagram of Fig. 6 assembling process, according to second form of implementation, in input vertical shaft zone, cable that will be mounted and/or hollow pipe be placed with an assembled hose and

Fig. 7 A, 7B and 7C have provided the cross section of buried pipe respectively, and assembled hose wherein, the cable that is mounted and/or hollow pipe are under the different laying states.

For in the existing underground piping that has laid 1, in underground sewer, settle cable and/or hollow pipe 2, as shown in Figure 2, is to be pulled out by a feed volume 4 with reference to the flexible pipe 3 that is folded into flat band one with the cross section, be lowered in the vertical shaft 6 by a draw roll 5, the latter is in vertical direction between surface 7, street and underground piping 1 or raceway groove 8.This flexible pipe 3 can be weaving flexible pipe and/or a flexible hose, and it is by resin impregnation, thus this flexible pipe 3 or roll over thus the flat band that obtains light, flexibility, easy to use arranged.In the process that this flexible pipe 3 is sent into, send down cable or flexible hollow pipe by the roller 11 of getting the raw materials ready, the unreel that for example are placed on the delivery truck 9, walk around a deflecting roller 10, send down with the flat flexible pipe of folding.In draw roll 5 regions, this cable and/or hollow pipe 2 can be relatively with point mode be fixed in the flat flexible pipe 3 of folding above, thereby these cable/hollow pipes 2 can not be relatively moved.Flexible pipe 3 can be drawn in the passage 1 by means of the drawing rope along direction tractive shown in the arrow 12 in vertical shaft 6 with cable/hollow pipe 2.By vertical shaft 6 easily in the admission passage 1.Flexible pipe 3 is drawn in the passage subsequently, and is pulled to another place, unshowned gateway in Fig. 2 always, as another vertical shaft place, thus can be there near this end.Flexible pipe 3 is on the bottom surface of underground piping 1 with the cable/hollow pipe 2 that is positioned at above it, shown in dashed lines among Fig. 2 13 or among Figure 1A shown in the cross sectional representation of underground piping.Next flexible pipe 3 is cut and sealed in two opened end portions from feed volume 4 and reach air-tightness.By one of these two ends that are closed at least, blast compressed air by the compressor of installing on the truck 9, flexible pipe 3 is blown stick out, and thereby press against on the inwall of underground piping 1.Like this, cable/hollow pipe 2 is pressed against on the top of underground piping 1, shown in Figure 1B.Be in this nestling on the position on the inwall of underground piping 1 at flexible pipe 3, the difference according to flexible pipe 3 kinds of using makes its curing with distinct methods respectively.For example, if flexible pipe 3 flooded the resin that a kind of effect of being heated can be hardened, just heat, so that hardening of resin in the inside of flexible pipe 3.For the hardenable situation of using of the resin hard to bear ultraviolet ray-radiation of energy, carry out irradiation by suitable radiation appliance with Infrared in the inside of flexible pipe 3.After flexible pipe 3 hardens, just internal pressure can be got rid of.Cable and/or hollow pipe 2 are sent to a transmission station 14 and fixing subsequently, and this transmission station is fixed on the wall of vertical shaft 6, is easy to approaching.The end of flexible pipe 3 subsequently just can be fixing suitably in the transitional region of vertical shaft 6 at underground piping 1, makes that the intermediate space between the outside of the wall of underground piping 1 and flexible pipe 3 is sealed.Shown in Figure 1B like that, passage 1 thereby be provided with a smooth liner, it is protected simultaneously and seals with the cable or the hollow pipe 2 that nestle on the inwall of underground piping 1.Can with the cable of necessity, as the data transfer cable of fibre optics cable form, draw among the hollow pipe 2 that is placed between tube 1 and the flexible pipe 3 from passing on station 14 later on.

What go out as depicted in figs. 1 and 2 is such, this in existing underground piping, underground piping system or underground pipeline network, settle the method for cable and/or hollow pipe afterwards, but be a kind of method in common very flexibly, and can utilize existing underground piping system to extend communication network.

Described above is a kind of method that the flat flexible pipe 3 of folding of application flexibility is installed cable and/or hollow pipe 2 in existing buried pipe system.What provide among Fig. 3 A is the cross section of a underground piping 1.Wherein provided the pipe profile that is folded to form by a deformable plastic tube.See that on cross section this plastic tube is inwardly folding from its edge, promptly two edges are folding downwards, and toward each other.Article one, the pipe that is out of shape like this as making with plastic material, demonstrates certain shape stability, as shown in Fig. 3 A under folded state.Above the flexible pipe 3 under this folded state, lay and fixing cable/hollow pipe 2 again, thereby they are towards the wall on underground piping top.After this flexible pipe 3 is positioned properly in underground piping 1, flexible pipe is out of shape by means of heated medium and under the effect of internal pressure, again return to original pipe cross section, thereby it has spread an inner surface for underground piping 1, and simultaneously cable/hollow pipe 2 is pressed against on the inwall of underground piping 1, shown in Fig. 3 B.

The above is to have used the method for flexible pipe as the liner of tubulose.And Fig. 4 A schematically provides is underground piping 1, and it extends between two vertical shafts.Be that with ways and means difference described above in shown in Fig. 4 A, single pipeline section 16 is put down from a vertical shaft 3, by means of a push unit 17 by section be pushed in the underground piping 1.Here, single pipeline section 16 is pegged graft mutually, is welded to one another, and perhaps utilizes screw thread to be screwed in together each other, thereby is connected to each other.Simultaneously, lay cable/hollow pipe 2 at these on above the pipeline section 16, and push ahead with pipeline section 16.These cable/hollow pipes 2 can directly be transported by a deposit automobile according to shown in Figure 2.After pipeline section 16 was delivered to second vertical shaft 3 forward, cable/hollow pipe 2 was admitted to a transmission station 14 again and is fixed there.The Len req of cable/hollow pipe 2 just can be retained down when first pipeline section 16 is admitted to underground piping 1, and these cables or hollow pipe can be extended to changes 14 places, station.If wish, next can in intermediate gaps that may leave or annulus, clamp-on sealing material 15, such shown in Fig. 4 B.

In Fig. 5, schematically provided the net structure of using said method to carry out.For example, set up a new information transmission network, preferably select the main underground piping 1 that has laid of a underground pipeline network, discharge of wastewater pipeline for example, be used, so as between per two adjacent transmission stations 14 liner of a tubulose of use as described above, for example flexible pipe 3 or a plurality of pipeline section 16 are installed many single cable/hollow pipes 2.By existing house joint, be house connection-underground piping, it enters the waste water in a house 18 in the underground piping 1, here also indicate with 1, liner by drawing in a tubulose, preferably select flexible pipe 3 for use in this case, lead/hollow pipe is brought into and they are stuck between this flexible pipe and the buried pipe 1.In house 18, settle a transmission station 14, so that being connected to newly-established network, this resident family gets on.In the transitional region between the main underground piping 1, a special link position 19 can be set at house connection-buried pipe 1, feed house 18 so that there cable/hollow pipe 2 is carried out necessary branch process.

Second embodiment as shown in Figure 6 also is at existing underground piping 101, as a underground piping lay cables and/or hollow pipe 102 to be installed subsequently again.For this reason, still in the zone at vertical shaft 103 places between surface 107, street and underground piping 101 on the vertical direction, prepare the supply material 104 of what a flat assembled hose 105 that stacks.In addition, 103 places get the roller 106 of getting the raw materials ready ready at the supply vertical shaft, are twining the cable/hollow pipe 102 that will lay on it.This roller 106 of getting the raw materials ready for example can carried by truck 108.From truck 108, cable or hollow pipe 102 are broadcasted in the vertical shaft 103 vertically downward by a deflecting roller 109 that is equipped on truck 108 afterbodys.Below deflecting roller 109, on a platform 100, be mounted with a container 111, wherein holding fabricated material 112 with viscosity.On the approximate centre position of container 111, also be mounted with a coating unit 113, it has two guiding and applicator roll 114.Cable/the hollow pipe 102 that gets off from deflecting roller 109 is worn between them and was sent.When cable/hollow pipe 102 is fallen, they at coating unit 113, guiding and applicator roll 114 places by fabricated material 112 from each face, promptly be stained with profit from the two sides.

The fabricated material 112 is here preferably selected two components-epoxy resin for use.

Cable/hollow pipe 102 of being stained with profit like this hangs down below platform 100, with assembled hose 105 and together, and be placed in it above.For this reason, assembled hose 105 unclasps from feed volume 104, through first deflecting roller 115 and second deflecting roller 116 that is erected in vertical shaft 103 edges, wherein particularly second deflecting roller 116 guaranteed, assembled hose 105 is flat band at it in the zone that cable/hollow pipe 2 moves.

Assembled hose 105 can be silicone tubing or rubber hose.

Assembled hose 105 is admitted in the underground piping 101 in the bottom of vertical shaft 103 subsequently with cable and/or hollow pipe 102 placed on it, that be stained with profit with fabricated material 112.In this process of deployment, assembled hose 105 is drawn into along the direction of arrow 117.For this reason, can fix a pull rope in the end of unshowned assembled hose 105, it belongs to a draw-gear not shown further, and this draw-gear is drawn to vertical shaft 103 places that another is connected with underground piping 101 with assembled hose 105.

As seeing among Fig. 6, in the container 111 of fabricated material 112, additionally be placed with two bundles 118 of carrying band 119, for example form is a braid over braid.They are assembled material 112 dippings, and coated subsequently and guide roller 114 guides and is placed on the cable/hollow pipe 102 that will lay from the two sides.

When assembled hose 105 and the cable/hollow pipe 102 that is positioned at above it, also comprise in case of necessity extra carrying band 119 be admitted to go in the underground piping 101 after, the end at another vertical shaft that is not illustrated 103 places that is not illustrated on the assembled hose 105 is closed, and separates with feed volume 104 at vertical shaft shown in Figure 6 103 places.Next the pump on the truck 108 being linked to each other with the inner chamber of assembled hose 105, blast fluid to the flexible pipe inner chamber, is good with air.

The assembled hose 105 and its cable/hollow pipe of laying above 102 and two carrying band 119 residing states that are pulled in the underground piping 101 have been shown among Fig. 7 A, a band wherein is between assembled hose 105 and cable/hollow pipe 102, and another is then on the upper surface of cable/hollow pipe 102.This position from shown in Fig. 7 A blasts air in the inner space of assembled hose 105 by pump, sticks out thereby assembled hose 105 is blown, shown in Fig. 7 B.Along with assembled hose 105 is blown and sticked out, under the effect of pressure, cable/hollow pipe 102, and between carrying band 119, is pressed against on the upper surface of underground piping 101 in fabricated material 112 by potting.
