Definitions
- the present invention relates to a method for the construction, in a fast, safe and efficient way, of structures such as railway, motorway, road, pedestrian or other passages, through embankments or earthworks of any kind supporting one or more railways , highway, highway or other without requiring the prolonged stop of the traffic flowing on these ways.
- ⁇ transversal sinking under the slope, of two pairs of half-abutments or recessed piers, arranged in pairs facing each other on either side of the edges delimiting the passage to be made and sparing under the tracks, between these and the upper face of the half-abutments, a limited embankment thickness.
- the half-abutments are brought in pairs abutting substantially in the median longitudinal plane of the slope, and then claved in their mutual junction zone on either side of this median plane.
- the sinking consists of using jacks supported on one side on at least one of the half-elements so that each of these half-elements alternately serves as an anchor point for the other, in order to offer a suitable reaction to the thrust of the cylinders.
- the driving of the two half-elements is carried out by means of cables crossing the slope, each cable being fixed at one end to a half-element and secured to the other of a jack resting on the other half-element. , so as to exert on the cable a tensile force ensuring the mutual rimpedement of the two parts of the frame. It should be noted that this method requires the prior installation of auxiliary aprons or temporary stiffeners.
- the frame therefore has, on each of its vertical lateral sides, two extensions extending, for the first in the extension of its upper horizontal side and for the second disposed at an angle, so as to connect the opposite end of the extension to the base of the vertical side of the frame, the second extension having an inclination to the vertical substantially identical to that of the slope side facing.
- the "umbrella" vault which consists of drilling under the track in the terrain of the embankment that supports it, relatively small holes of small diameter arranged side by side and extending transversely under the track, these holes allowing the setting in place of hollow metal tubes in which may optionally be injected concrete so as to achieve after curing thereof piles or the like horizontal, or massive rigid sections which thus strengthen the ground by arming it, under the railway or the road, forming above the passage or tunnel to achieve, a kind of rigid bed consisting of the juxtaposition of these tubes or rigid profiles. The ground can then be excavated before the construction of the tunnel walls without risk of collapse of the track.
- the bed thus created may have a planar or curved profile, above the passage or tunnel to be formed transversely in the slope.
- Autofonçage which consists in arranging facing each other, on either side of the embankment supporting the track, two half-abutments or similar structures, in the form of identical hollow frames, closed or with a half-U section, prefabricated reinforced concrete, the wheelbase of which corresponds substantially to the section of the tunnel to be produced, the frontal zones directed toward each other of these frames being preferably partially hollowed out to each form a nose with vertically inclined edges, these frames being progressively brought closer to each other across the slope by means of traction cables controlled by hydraulic cylinders of very great power, the system being arranged so that the two frames move simultaneously one towards the other or in turn, one of them being immobilized while the second is moving towards the first or vice versa.
- these cables are secured respectively to one of the frames and a jack carried by the other frame so that the forces developed on these cables, by an appropriate mounting of the cylinders, cause the penetration of the frames in the slope and their relative movements from one to the other.
- the land of the slope in front of the frames as and when they are reciprocated or reciprocated, is eliminated continuously, until, in the middle plane of the structure, parallel to the direction of the track on the top of the slope, the two frames meet with contact of their beaks opposite, these frames being then clavés them in their junction zone to ensure the continuity of the tunnel thus realized under the way.
- the improvement therefore consists in combining this method with that of an umbrella vault forming above the moving frames, a support bed in such a way that any interruption of the traffic is avoided, eliminating the reaction forces and the effect lifting the resulting path and allowing further that the vault is permanently supported over the entire length of the tubes or profiles that constitute it.
- the sliding interface consists of load modules in sufficient number and corresponding to the weight of the work to be moved.
- the load module carrying trays are filled with compressed air so that the work can be slid on the sliding paths with a coefficient of friction almost zero.
- the air supply is provided by compressed air cylinders arranged in vertical frames positioned on the deck. Any settlement of the shifting paths can be compensated by a separate operation of the hydraulic cylinders of the load modules and this as part of their maximum stroke.
- the shifting movement is stopped, the trays carrying load modules are put in the air and the work is deposited on its final supports in a similar way to the lifting process.
- auxiliary aprons or temporary stiffeners to maintain traffic on the tracks carried during the implementation of the structure. It should be noted that the installation and removal of the auxiliary aprons is done using a very specific railway material and available (and therefore expensive) about forty meters in length and equipped with lifting trolleys: the gantry hydrocampe.
- the subject of the present invention is a method which makes it possible to remedy these drawbacks, in particular by making it possible to reduce the costs and delays of the passage to be made.
- the method provides for carrying out only the apron of the passage in a first step. After having interrupted all or part of the track traffic for a very short period of time (a few hours) and removed the corresponding rail or road tracks to this traffic, earthworks start cutting to reach corresponding rib at the underside of the apron (possibly increased by a few centimeters to allow a fine leveling of the apron seat). Next, the deck will be poured on site after having put in place a suitable form of cheeks like manuportable panels or others as well as preassembled reinforcement cages and their recovery on site.
- the concrete used will be of high type performance, ultra-high performance or UHPC (Ultra-High Performance Fiber Concrete) can reach a high enough resistance in just a few hours, allowing the deck to be sealed eventually backfilled and returned to traffic just at the end of the period traffic jam. After drying the concrete, the deck will receive, if necessary, a seal of independent type, semi-independent, dependent or any suitable process and will be backfilled with good quality materials such as treated or other serious. The rail, road or pedestrian traffic will then be restored after reconstruction of the tracks, roads or tracks.
- UHPC Ultra-High Performance Fiber Concrete
- the deck can also be prefabricated in one or more elements, which will then be ripped, crowned with using mobile cranes or moved by any other system, then keyed together on site or assembled if necessary by prestressed cables or other.
- the deck can also be made in a mixed steel / concrete structure.
- An alternative is to make the reinforced or prestressed concrete deck and combine two or more of these materials and techniques of implementation.
- the piers will be made by digging subterranean galleries in the embankment supporting the rail, road or pedestrian ways, at the ends of the concrete sleeper already made during the short period of traffic interruption.
- the galleries will have a width equivalent to that of the piers.
- the shielding shall consist of HEB type metal sections or similar screens shielded by sheet steel, wood, concrete or any other material. All the elements composing this shielding are manuportables. Some of this material will be abandoned in the field and the other part will be recovered later during earthworks.
- the front face will be dug manually using hand tools or other, in small passes depending on the soil encountered (about one meter) to ensure at all times a slope according to the natural slope field in place, the aim being to avoid a possible collapse of the latter. As a result, the shielding and excavation of the gallery are done simultaneously.
- the pedestal will be extended to a sufficiently hard bedrock based on temporary and / or permanent foundations (this depends on the nature of the lands encountered, whose lift varies from one place to another, as well as the dimensions and shapes of the foundations).
- the reinforcement of the piers will be realized by the installation of pre-assembled reinforcements or the assembly inside the galleries of cut and shaped frames.
- Concreting piers will be made with a self-compacting concrete or vibrated after closing abouts using a specific formwork tool. It can also be achieved using high performance concrete, ultra high performance fiber concrete or the combination of two or more of these materials.
- a draining geocomposite drainage system or other suitable system will be interposed between the final "lost" armor of the tunnel and the existing ground.
- excavation excavation inside the frame thus formed can begin between the piers and under the cross.
- part of the armor will be deposited, the deck possibly supported and the piers stabilized provisionally and / or permanently to using anchor bolts, passive or active nails, bumpers and liernes or any other suitable system.
- the combination of two or more of these techniques may be considered.
- the bottom of the excavation will be compacted, scraped and concreted to make the final foundation if necessary (according to the wishes of the client and / or the justification of the calculation notes).
- This method therefore provides a solution to the various disadvantages of the conventional processes, by removing in particular:
- Another advantage of the method that is the subject of this invention consists in producing both isostatic and hyperstatic structures or both at the same time, by producing fixed and / or mobile supports.
- the accompanying drawings very schematically recall, in cross sections and longitudinal, the method of making a passage according to the invention.
- Figures 1-a and 1-b show: The removal of the tracks, disbursement to the right of the structure to the level of the underside of the cross of the passage then realization of the latter.
- Figures 2-a and 2-b show: Backfilling above the deck, rests lanes with restitution of traffic and excavation galleries sub-work in successive passes.
- Figures 3-a and 3-b represent: The continuation of the digging work of the galleries to the last pass and the soles.
- Figures 4-a and 4-b show: The reinforcement of the piers and soles.
- Figures 5-a and 5-b show: Concreting piers and soles.
- Figures 6-a and 6-b show: Earthworks inside the passage to the level of the raft.
- Figures 7-a and 7-b show: The realization of the raft and end of construction of the passage.
- Figure 8 shows: A cross section of the completed underground passage.
- the method provides, after cutting the train traffic for a few hours (the time of a weekend for example) and deposits tracks railways (3) to the right of the future passage (materialized in dashed line by the location (5) of the future piers and the location (6) of the future base) to be realized in the slope (1) supporting these routes, to execute a small disbursement (2) in the embankment, having as a bottom of excavation the underside of the future deck (4) to be made according to Figure 1.
- a sealing complex 7) adapted and will be backfilled with suitable materials (8).
- the tracks (9) can be rested above the deck and ballasted before the return to traffic of rail traffic at the end of the period of interruption.
- the work of making the piers (10) can begin. Indeed, they will be made by digging galleries having a width equivalent to that of the final piers, in successive passes, manually shielded as the progress of the earthworks executed with the help of tools manuportables. The digging of the galleries will continue until the level of the soles (11) superficial of the piers. These may be temporary or permanent (their dimensions and geometries depend on the terrain encountered on site and will be large enough to allow the work of companions in better safety conditions). At the end of the earthworks, the frames (12) will be implemented and formwork tools completely close the ends of the galleries on their full height.
- the concreting of the piers can then begin by filling the galleries with a self-compacting concrete (13).
- earthwork sub-work (14) After hardening of the piers, earthwork sub-work (14) will be executed inside the passage with the help of gear adapted while placing butters and liernes (15) at the mid-height of the piers.
- Wing and / or return walls (17) can then be constructed, the equipment set up in a conventional manner and the piers dressed (these operations are not part of the process since they are independent of the temporary cut of the traffic:
- the process concerns the realization of the structure of the passage: Supports, deck, foundations and possible dismantling). It goes without saying that the invention, of course, is not limited to the embodiment more specifically described above with reference to the accompanying drawings, but other variants, falling within the scope of the following claims, are likely to apply according to the same overall principle.
- the method according to the invention allows the construction of works such as railway, highway, road, pedestrian or other passages, through embankments or earthworks of any kind supporting one or more railroad tracks, highway or road without requiring the prolonged stoppage of the traffic flowing on these tracks.
