Definitions
- the invention relates to a method for laying an elongated structure (s) suitable for conveying a flow, as well as a vehicle for laying such structure (s).
- a preferred application of the invention relates to the laying of telecommunication cable (s) and in particular of optical fibers.
- the object of the invention is to make quick, easy and at a lower cost price, the laying of a (or a series) of said (s) structure (s) on a "hard” track, that is to say an elongated infrastructure covered with a coating of bitumen, asphalt, tarmac, concrete, or equivalent products, made from an agglomerate.
- a notch of a depth can vary between about 10 mm and 200 mm and width can vary between about 5 mm and 50 mm, - to extend longitudinally ent the notch in the way so that one has there (the) elongated structure (s) ( s),
- a filling product such as a resin, compatible with the agglomerate
- the speed of advance of the machine provided for making the cuts will also be able to be high (one must be able to reach the three kilometers per day fairly easily and one hopes for five kilometers per day).
- the width and the depth of the notch can be further reduced to a depth and a width less than approximately 50 mm and 25 mm respectively (the numerical data of this description being all provided at most to the nearest 20%).
- One of the advantages of the invention is, as already indicated, to be able to work quickly and well, without having to carry out heavy earthworks on a track, such as a roadway or a track, already built .
- an important additional characteristic of the invention provides that the notch is made from the outer (or upper) surface of the rolling bearing.
- the notch will therefore be directly exposed to the displacement on it of possible heavy vehicles, without the interposition of intermediate layer (s) of coating between them and the vehicle.
- the invention has provided that in at least one intermediate place of its length, the notch can be interrupted, then restarted again at a few distances, a box being produced near this interruption, out of the way in order to contain a reserve of length of the envisaged structure and / or a connection block.
- an additional characteristic provides for making this notch preferably at the edge of the lane, for example in the stop lane d 'emergency of a motorway, away from the part of the lane where at least most of the traffic takes place (it should be remembered that the notch is preferably intended to be produced substantially parallel to the longitudinal direction in which stretches the way).
- the structure to be laid in the notch is a (or a series of) electric cable (s), such as telecommunication cables or optical fibers
- another characteristic of the invention advise to interpose a heat shield between the structure and the filling product. This will improve a possible temperature sensitivity of at least part of the structure (freezing, excessive heat, resulting in particular physical changes to the coating, etc.).
- the laying machine it is provided in the invention that, to satisfy the conditions already set out, it includes:
- the filling product will be a resin, and in particular a "bituminous" resin compatible with the existing bituminous coatings for roadways.
- the laying vehicle of the invention will advantageously include:
- Figure 1 is a partial schematic perspective view of a section of roadway or track in which a notch receiving a cable has been shown
- Figure 2 is a local view on a larger scale of the front of the area marked II in Figure 1, once the installation is finished;
- Figure 3 is a partial top view of a highway area showing more particularly the emergency stop strip and the cradle, with a connection box;
- Figure 4 is a sectional view along the line IV-IV of Figure 3;
- Figures 5 and 6 are two views, respectively in perspective and from above (on an enlarged scale) of a laying machine according to the invention;
- FIG. 7 schematically shows how the notch will be able to be produced;
- FIG. 8 also schematically shows the principle of laying the elongated structure to be put in place in the notch, assuming that it is a cable such as an optical fiber to be covered with a continuous strip of thermal protection;
- FIG. 9 schematically shows the means and the manner for recapping the notch, at the end of installation.
- FIG. 1 a section of highway pavement 1 is shown. But it could also be a road or other section, suitable for the movement over it of machines or vehicles.
- the coating shown diagrammatically as a whole 3 comprises, in the illustration of FIG. 1, a first (deepest) sub-layer 5, for example essentially in gravel, surmounted by a first intermediate layer 7 of bituminous type, itself surmounted by a thinner layer 9, also bituminous, the upper surface 9a of which forms the rolling or moving surface of any vehicle, machine and other, intended to rest on this coating.
- Layers 7 and 9 can be asphalt layers.
- the surface 9a will be called “rolling surface”.
- the narrow and shallow notch 11 will have a depth p of between approximately 10 mm and 200 mm and a width 1 of between approximately 5 mm and 50 mm.
- the depth p can be reduced less than 50 mm and the width 1 between approximately 8 mm and 25 mm, thereby increasing the ease and speed of making the notch, while limiting its possibilities of alteration due in particular to the rolling of very heavy vehicles on the surface 9a.
- the length of the notch 11 may be several kilometers, or even several hundred kilometers.
- the cable 13 to be put in place has been placed in the bottom of the notch 11, as in FIG. 1.
- This cable includes a whole series of coaxial optical fibers 13 ′, conventionally placed in a sheath 15.
- the notch 11 is closed by a filling product 17 which extends over the entire length of the notch, along the cable.
- the filling product 17 presses the cable towards the bottom of the notch and its upper surface 17a is substantially flush with the surface 9a of the covering.
- the product 17 may for example be a bituminous resin for filling the notch, applicable when hot (about 150 ° C.) and suitable for adhere against the side walls of the cut, thus preventing water from entering the cut.
- a “retarding” thermal protection screen, 19, may be interposed between the filling product 17 and the structure 13. It may be a strip that can be continuously unrolled over the structure, before placing the product 17.
- the structure 13 will be a fiber optic telecommunication cable with a diameter less than or equal to approximately 9 mm, the width of the notch then being approximately 1 cm and its depth approximately 2 cm. .
- the cable 13 will have only a fairly small clearance in width in the notch.
- a highway road lane has been identified at 21, at 23 a section of emergency stop strip and at 25 the bucket or the road shoulder, not coated with bitumen or concrete .
- the general direction 110 for developing the notch extends substantially parallel to the longitudinal axis 210 of the motorway lane.
- the area in which the cut was made could be a gutter edge (asphalted part along the gutter itself) or a sidewalk, or even a cycle path, or another coated aisle.
- the notch has two sections 11a, 11b, to be connected in a connection box 29 buried at least in part, 29, the mark 27 marking the interruption between the sections.
- the housing 29 (for example made of plastic or concrete) has been placed in a hole dug for this purpose in the uncoated ground 25. There emerge, each after an elbow, the two notches 11a, 11b, so that two sections 13a, 13b of cable can pass there and (with a spare over-length) connect to each other, at the place of a connection socket or a connection block 31 from which a cable starts here 32 intended to distribute to an external user the electric flow brought for example by the cable 13a.
- This vehicle 33 comprises a chassis 35 provided with a control station 37 (steering wheel, pedals, indicators, displays, etc.) making it possible in particular to control the driving wheels 39 and to steer the steering wheels 41, in connection with a motor. 43, such as a heat engine associated with a hydraulic power plant.
- a control station 37 steering wheel, pedals, indicators, displays, etc.
- It may be a saw or cutter (marked 45 in Figure 7) equipped with a protective cover and therefore suitable for making the notch 11 that we see appear at the rear of the vehicle, after passing the cutter.
- a transfer case with a laterally movable arm is shown diagrammatically for lateral adjustment (relative to the direction 47) of the cutting means 45a.
- Means (not shown) for vertical adjustment of the position of the saw in height are also provided.
- retractable wheels 51 located on either side of the saw have been shown.
- a sawing disc 45a belonging to the unit 45 is in the process of sawing the notch 11 in the covering 9, from its rolling surface 9a, under the impulse of a motor 63.
- the suction and filtering means 53 recover the cutting waste, via a chute 65.
- the cable 13 is wound continuously around a reel 66, carried by the vehicle frame schematically very briefly at 35.
- This same frame 35 also carries a second drum 67 around which the continuous strip of thermal protection 19 intended to be put in place over the cable 13 in the trench 11, once the cable has been installed therein thanks to the laying unit 59 of which only four rollers have been shown for unwinding and guiding the cable, identified as a whole 69, four rollers of the same type having been referenced at 71 for the guided unwinding towards the trench 11 of the heat shield strip 19.
- the cable 13 and its thermal protection 19 are installed along the notch 11, the surface access of which is being blocked by means of the resin injection nozzle 77, under the impulse of the injection pump 79.
- a resin mixer, 81, belonging to the unit 61 (such as the nozzle 77 and the pump 79) makes it possible to prepare this resin and to keep it ready for injection.
- a controlled roller mounted on a shaft and placed under the control of a motor (not shown) also allows, at 83, to ensure a smoothing finish of the filling resin 17, substantially level with the surface 9a.
- a nozzle 85 blows pressurized air, under the control of an air compressor 87, to clean the residual dust possibly contained in the part to be filled with the notch.
