Description

Technical Field

[0001] This invention relates to a method for erecting a transport structure comprising two components formed by tube sections, each component capable of being placed under low air pressure, and a cabin capable of traveling through the component with substantially no air friction. Such a transport system is commonly referred to as hyperloop technology. The invention also relates to a corresponding transport structure. Background Technology

[0002] Hyperloop technology is a proposed high-speed transportation system for both passenger and freight transport. This high-speed transport system is essentially a sealed tube system with low air pressure, through which cabins can travel with virtually no air resistance or air friction. The high-speed transport system has three main components: the tube, the cabin, and the station. The tube is a large, sealed, low-pressure system that can be built above, below, or on the ground. The high-speed transport system includes the necessary infrastructure to ensure levitation / suspension, propulsion, braking, etc. The vehicles operate within this controlled environment and are generally referred to as cabins. Cabins employ electrolevitation (electromagnetic or electric levitation) or aerodynamic levitation (using air bearings for gliding) and electromagnetic or aerodynamic propulsion to glide along fixed guide rails. The station is a facility where cabins can be started or stopped, and where passengers can board / alight and cargo can be loaded / unloaded. A station is located at each end of the sealed tube system.

[0003] From an artist's perspective, the above-ground Hyperloop structure is often represented in the form of pipe sections, the ends of which are simply resting on regularly spaced piers. This design is very appealing, but it doesn't provide a full understanding of the significant challenges during the installation process. One of these challenges is that the pipe sections are massive pieces that cannot be easily transported to the construction site, especially in steep or inaccessible terrain, or where the Hyperloop route is far from existing roads. To avoid transporting the pipe sections, the use of mobile pipe-producing machinery (such as...) is specifically known from US9517901. Figure 9 The pipe manufacturing and assembly shown in Figure A is carried out on land, and the pipe production machine is operable to move on land and be guided along the construction route. Alternatively, mobile in-situ manufacturing systems (such as...) Figure 9The structure shown in Figure B) can be located at a single location to manufacture multiple pipe segments (e.g., fifty pipe segments) and then subsequently moved to a new location. In both cases, the Hyperloop route can only be built if mobile production machinery or mobile manufacturing systems can access the construction site. Furthermore, among other disadvantages, it is worth mentioning that energy supply can be challenging while moving along the construction route, and new electrical certifications may be required each time the machinery / system is moved. Summary of the Invention

[0004] Therefore, the object of the present invention is to overcome the shortcomings of existing methods and structures by providing a method for erecting ground transport structures, a method adapted to rugged terrain, and a method that makes the transport and assembly of different components of the structure easier.

[0018] ○ A metal structure embedded in a pipe section within a second assembly formed by pipe sections, the upper surface of which is part of a second roof-type transport path.

[0019] The method includes: using a vehicle (17) to transport the main beam (6) of the first plurality of main beams and the main beam (6) of the second plurality of main beams along a first roof-type transport path (7) formed by the main beams of the first plurality of main beams previously positioned, alternately positioning the main beams at their use positions at the second end of the first roof-type transport path and the second end of the second roof-type transport path, and returning the vehicle along the second roof-type transport path formed by the main beams of the second plurality of main beams previously positioned to the first end of a portion of the transport structure.

[0020] The method according to the invention may also have the following optional features, considered individually or in combination:

[0021] - The transportation structure does not include any platforms that form the transportation path.

[0022] - The method includes the first step of erecting the pier.

[0023] - The method includes an additional step in which a first section of the transport structure is erected at the storage point, the first section comprising at least one pier, a beam among a first plurality of beams, and a beam among a second plurality of beams.

[0024] - The vehicle is fitted with a main beam at the first end of the transport structure section.

[0025] - The main girder is positioned using a girder placement crane supported by the structure itself.

[0026] - The main beam is manufactured at the reserve point.

[0027] A second aspect of the invention includes a portion of a transport structure for enabling a cabin to move substantially without air friction within an assembly formed by tube sections and placed under low air pressure. This portion of the transport infrastructure includes:

[0028] - Multiple piers, spaced substantially regularly along the longitudinal axis X of the transport structure section.

[0029] - A first plurality of beams formed by the main beams, the first plurality of beams being positioned on at least some of the piers and forming the following:

[0030] ○ A first component formed by the tube section, which can be placed under low air pressure and allows the cabin to circulate within the tube section with virtually no air friction.

[0031] ○ A first roof-type transport path extends from a first end of the transport structure to a second end.

[0032] Each of the first plurality of main beams includes:

[0033] ○ The pipe section in the first component formed by the pipe section,

[0035] - A second or more main beams formed by the main beams, the second or more main beams being positioned on at least some of the piers and forming the following:

[0036] ○ A second component formed by the tube section, which can be placed under low air pressure and allows the cabin to circulate within the tube section with virtually no air friction.

[0039] ○ The pipe section in the second component formed by the pipe section,

[0040] ○ A metal structure embedded in a pipe section within a second component formed by pipe sections, the upper surface of which is part of a second roof-type transport path.

[0041] The transport structure according to the invention may also have optional features listed below, either individually or in combination:

[0042] - The transportation infrastructure does not include any platforms that form service routes.

[0043] - All the main beams in the first plurality of beams are positioned one after another and continuously along the longitudinal axis X of the transport structure section, and all the main beams in the second plurality of beams are positioned one after another and continuously along the longitudinal axis X of the transport structure section.

[0047] - The upper deck is a basically flat surface suitable for vehicular traffic.

[0048] - The transport structure also includes a third or more beams formed by beams positioned on a first or more beams formed by beams and / or a fourth or more beams formed by beams positioned on a second or more beams formed by beams.

[0049] Clearly, this invention is based on the construction of a structure consisting of piers and beams, the beams comprising sections of a high-speed transport system, capable of transporting heavy components similar to the beams. The structure includes a circulation loop, allowing vehicles, starting from a reserve point and circulating along the already positioned sections of the structure, to transport each additional component of the transport structure to its location at the construction point and return to the reserve point without obstructing other vehicles from transporting the next component to the construction point. Therefore, the transport structure can be easily constructed regardless of terrain.

[0050] Other features and advantages of the invention will be described in more detail in the following description. Attached Figure Description

[0051] The invention will be better understood by referring to the following figures and reading the following description, which is provided for illustrative purposes only and is in no way intended to be restrictive:

[0060] - Figure 9 The illustration shows vehicles returning to the storage point along other rooftop transport routes. Detailed Implementation

[0061] It should be noted that the spatial relative terms used in this application, such as "lower," "below," "inner," "inward," "outer," and "outward," refer to the position and orientation of different components of the transport structure when the transport structure has been erected. The terms "upstream" and "downstream" used in this application refer to the direction of assembly starting from the storage point.

[0062] Reference Figures 1 to 3 According to the invention, part 1 of the transport structure firstly includes: a plurality of piers 3; a first plurality of beams 4 formed by beams 6, the first plurality of beams 4 being positioned on at least a portion of the piers (i.e., positioned on at least some of the piers) and forming a first roof-type transport path 7 extending from a first end portion of the transport structure to a second end portion; and a second plurality of beams 5 formed by beams 6, the second plurality of beams 5 being positioned on at least a portion of the piers (i.e., positioned on at least some of the piers) and forming a second roof-type transport path 10 extending from the first end portion of the transport structure to the second end portion alongside the first roof-type transport path 7.

[0063] The transport structure comprises multiple segments, preferably at least three segments. The segments are defined by the length of the main beams. The segments are preferably matched to the distance between two consecutive piers along the longitudinal axis X of the transport structure segment.

[0064] Pier 3 is an upright support member for a structure or superstructure, such as an arch or bridging member. Pier 3 supports the superstructure and transfers the load of the superstructure to the foundation. The shape of the piers according to the invention is particularly unrestricted, as long as these piers can support beams.

[0065] according to Figure 1 The first variant illustrated is a frame pier, which consists of two or more columnar members supporting a pier cap. The pier extends substantially in a plane perpendicular to the route, i.e., perpendicular to the length of the main beam.

[0066] according to Figure 3 The second variant illustrated has a V-shaped pier. The V-shaped pier extends substantially in a plane perpendicular to the route, i.e., perpendicular to the length of the main beam. The pier comprises two outwardly extending inclined arms. Each arm can support a main beam. The pier according to this second variant may also include a pier cap in the form of a horizontal beam connecting the two arms. This pier cap provides an additional base for the main beam and better distributes the load from the main beam to the pier.

[0067] Optionally, the multiple piers can be divided into a first set of piers and a second set of piers. The first set of piers supports a first set of main beams, and the second set of piers supports a second set of main beams. The advantage of this design is that the space between the first roof-type transport path and the second roof-type transport path and / or the height of the first roof-type transport path and the second roof-type transport path can be easily adjusted according to the terrain.

[0068] Other shapes, such as Y-shaped piers, X-shaped piers, H-shaped piers, hammerhead-shaped piers, cantilever piers, trestle-type piers, solid piers, and simple columnar members are also possible.

[0069] The piers are spaced substantially regularly along the longitudinal axis X of the transport structure.

[0070] Part 1 of the transport structure according to the invention further includes a first plurality of beams 4 formed by beams 6, the first plurality of beams 4 being positioned on at least some of the piers 3 and forming the following:

[0071] - The first component of the tube section 14, which can be placed under low air pressure and allows the cabin to circulate within the tube section with virtually no air friction, and

[0072] - First roof-type transport path 7, which extends from the first end of the transport structure to the second end.

[0073] Therefore, each of the first plurality of main beams 6 includes:

[0074] ○ Pipe section 14 in the first component formed by the pipe section,

[0075] ○ Metal structure 20, which is embedded in the pipe section of the first component formed by the pipe section, the upper surface of which is part of the first roof-type transport path.

[0076] The main beam 6 is the supporting beam used in the construction. The main beam 6 can be made of steel or concrete, or it can be a composite structure. The main beam 6 can be a box girder, that is, a beam with a closed cross-section.

[0077] The design of pipe section 14 is not limited, as long as pipe section 14 can be directly or indirectly connected to each other along the longitudinal axis through its longitudinal ends to form the assembly as described above. In particular, the cross-section of the pipe is not limited. The cross-section of the pipe can be a circular cross-section or a polygonal cross-section.

[0078] The pipe section is preferably made of steel. Steel has the advantages of being lightweight, easy to vacuum seal, and recyclable.

[0079] According to a variation of the invention, the pipe sections are made of steel plates welded to each other.

[0080] According to another variation, the tube section comprises multiple wall sections joined together by their longitudinal edges. Adjacent wall sections are arranged edge-to-edge along the joint line. The edges of the wall sections may include flanges for ease of assembly. Each wall section may include at least one central panel and two side panels. The side panels extend circumferentially over the central panel on both sides of the tube section. The side panels laterally enclose the central panel. The side panels form an angle with the central panel. This type of wall section has the advantage of being easily obtained by simply folding the metal sheet. The side panels reinforce the wall section and increase the bending strength of the section in the longitudinal direction.

[0081] According to another variant, the tube section is a double-walled tube section, in which the space between the outer tube and the inner tube is filled with a reinforcing compound.

[0082] According to another variation, the pipe section includes multiple longitudinal beams installed to multiple circumferential sections to form a skeleton frame, on which skin sections are airtightly attached.

[0083] According to another variation, the tube section includes a plurality of elongated outer skin panels that form the outer wall of the double-walled tube section. The panels are curved, such that assembly of the panels forms a smooth cylindrical surface. The panels may have embossed indentations to improve resistance to buckling. The tube section also includes inner plate components that form the inner wall of the double-walled tube section, the inner plate components being welded to each other for an airtight connection and welded to the elongated outer skin panels.

[0084] According to another variation, the tube section includes: an elongated curved outer shell component that forms the outer wall of the double-walled tube section; an inner wall in the form of a regular N-sided polygonal tube; and an intermediate shell component that has a flat inner side and an outer side with the same curvature as the elongated curved outer shell component.

[0085] "Low air pressure" refers to air pressure that is below atmospheric pressure, preferably below or equal to 10 kPa, and more preferably between 10 Pa and 10 kPa.

[0086] In practice, the ability of an assembly to operate under low air pressure is determined by the characteristics of the pipe section walls and the connection between the pipe section and the pumping equipment. Specifically, the pipe section walls must be airtight. Different methods of making the pipe walls airtight are well known, and those skilled in the art will know how to select the wall characteristics in each particular case. Furthermore, the connection between two pipe sections must be airtight. Airtightness of the connection can be provided, in particular, by welding, by adding components such as elastomers between bolted or clamped pipe sections, or by means of expansion joints. Those skilled in the art know how to make connections airtight and will adapt connections to each particular case. Additionally, the pumping equipment must be precisely sized to allow low air pressure to be achieved and maintained within the assembly of the pipe section, while taking into account air leakage during operation. Those skilled in the art know how to do this and will adapt the pumping equipment to each particular case.

[0087] In practice, the ability of the component to allow the cabin to circulate within the tube section with virtually no air friction is provided by infrastructure positioned within the tube section, specifically providing levitation / suspension, propulsion, braking, etc. Such infrastructure is already well known, and those skilled in the art will know how to adapt the infrastructure to each particular situation.

[0088] The main beam also includes a metal structure 20 embedded in a pipe section within a first component formed by pipe sections, the upper surface of which is part of a first roof-type transport path 7.

[0089] exist Figure 2 In the first variant of the illustrated metal structure, the metal structure may include a lower deck 21, an upper deck 22, and a transverse stiffener 23 connecting the lower deck and the upper deck.

[0090] The lower deck 21 is essentially a horizontally extending, flat component. The lower deck 21 is preferably made of plate, such as steel plate. More preferably, the lower deck 21 is reinforced with longitudinal stiffeners 24. The lower deck increases the rigidity of the main beam and limits the deflection of the main beam between its supports.

[0091] The upper deck 22 may be a horizontally extending, flat component. The upper deck 22 is preferably made of plate, such as steel plate. More preferably, the upper deck 22 is reinforced with longitudinal stiffeners. The upper deck increases the rigidity of the main beam and limits the deflection of the main beam between its supports. The upper surface of the upper deck forms part of the first roof-type transport path 7.

[0092] The transverse stiffeners 23 extend substantially in a plane perpendicular to the longitudinal axis X of the portion of the transport structure. The transverse stiffeners 23 extend horizontally to define the width of the main beam and reinforce the lower and upper decks connected to them. The transverse stiffeners 23 extend vertically to define the thickness of the main beam and further reinforce it. Specifically, the transverse stiffeners 23 extend to the horizontal level of the top of the pipe section, or extend above the top of the pipe section, so that the transverse stiffeners 23 can be directly connected to the upper deck. Specifically, the transverse stiffeners 23 extend to the horizontal level of the bottom of the pipe section, or extend below the bottom of the pipe section, so that the transverse stiffeners 23 can be directly connected to the lower deck. The transverse stiffeners 23 are preferably spaced along the length of the main beam, i.e., along the longitudinal axis X. More preferably, the transverse stiffeners 23 are regularly spaced. The transverse stiffeners 23 can be made of, for example, a flat panel, a corrugated panel, or a flat panel reinforced with fasteners.

[0093] according to Figure 2 In a first variation of the illustrated metal structure, the transverse stiffener 23 extends horizontally to match the profile of the cross-section of the pipe section. The transverse stiffener 23 further reinforces the pipe section and the main beam. The transverse stiffener preferably comprises two transverse stiffening sections 25, one on each side of the pipe section. Specifically, the transverse stiffening section positioned on one side of the pipe section faces the transverse stiffening section positioned on the other side of the pipe section.

[0094] Alternatively, the lateral stiffener may include a lower horizontal beam positioned below the pipe section, an upper horizontal beam positioned above the pipe section, and at least one vertical beam connecting the lower and upper horizontal beams. Preferably, the lateral stiffener includes two vertical beams positioned on both sides of the pipe section, connected to the lower and upper horizontal beams to form a square cross-section embedded in the pipe section.

[0095] According to a second variation of the metal structure (not shown), the metal structure embedded in the pipe section may include transverse stiffeners and longitudinal stiffeners connecting the transverse stiffeners. The transverse stiffeners may be as described above. The longitudinal stiffeners are preferably beams, particularly I-beams. The longitudinal stiffeners may be positioned below the transverse stiffeners as lower longitudinal stiffeners and / or above the transverse stiffeners as upper longitudinal stiffeners. The main beam preferably includes two sets of multiple longitudinal stiffeners, i.e., one set of multiple longitudinal stiffeners on each side of the pipe section.

[0096] In this variant, the upper surface of the upper longitudinal stiffener forms part of a first roof-type transport path. Specifically, this upper surface includes guide rails that form a railway track, allowing railway vehicles to move along the track.

[0097] Each metal structure 20 of the main beam embeds a single tube segment. In other words, the main beam does not include the tube segment 14 in the second assembly formed by the tube segments, the tube segment 14 in the second assembly of the tube segments being positioned adjacent to the tube segment 14 in the first assembly of the metal structure.

[0098] Preferably, each main beam 6 extends from one pier to an adjacent pier. Specifically, a first end of the main beam rests on a given pier, and a second end of the main beam rests on an adjacent pier along the longitudinal axis X of that portion of the transport route or transport structure. Thus, the main beams can be easily installed by simply positioning them on the piers. Alternatively, the main beams may extend on more than two piers.

[0099] A first plurality of main beams 4, formed by main beams 6, are positioned along the longitudinal axis of that portion of the transport route or transport structure to form a first roof-type transport path 7. Specifically, all the main beams 6 of the first plurality of main beams 4 are positioned sequentially and continuously, one after another, along the longitudinal axis X of that portion of the transport structure to form the first roof-type transport path 7. A roof-type transport path refers to at least one continuous track on the main beams, said at least one continuous track being designed to support the transport of heavy components and vehicles similar to the main beams. The roof-type transport path extends from a first longitudinal end of that portion of the transport structure to a second longitudinal end of that portion of the transport structure, regardless of the length of that portion.

[0100] According to a variation of the roof-type transport path, the upper surface of the main beam, especially the upper deck, is simply a basically flat surface suitable for vehicle traffic.

[0101] According to another variation of the roof-type transport path, the upper surface of the main beam, especially the upper deck, includes rails that form a railway track, allowing railway vehicles to move along the track.

[0102] Part 1 of the transport structure according to the invention further includes a second plurality of beams 5 formed by beams 6, the second plurality of beams 5 being positioned on at least some of the piers and forming the following:

[0103] - A second assembly formed by tube section 14, which can be placed under low air pressure and allows the cabin to circulate within the tube section with virtually no air friction, and

[0104] - Second roof-type transport path 10, which extends from the first end of the transport structure to the second end next to the first roof-type transport path.

[0105] Therefore, each of the second plurality of main beams 5 includes:

[0106] ○ Pipe section 14 in the second component formed by the pipe section,

[0107] ○ Metal structure 20, namely the second metal structure, is embedded in the pipe section of the second component formed by the pipe section, the upper surface of which is part of the second roof-type transport path 10.

[0108] The characteristics and variations of the pipe sections in the first component described above also apply to the pipe sections in the second component. The pipe sections in the first component and the pipe sections in the second component can be identical to facilitate logistics.

[0109] The features and variations of the metal structure described above also apply here. The main beams in the first plurality of beams and the main beams in the second plurality of beams can be identical to facilitate logistics. The limitations and variations detailed regarding the first roof-type transport route apply to the second roof-type transport route.

[0110] The second rooftop transport path 10 extends alongside the first rooftop transport path 7. "Opposite" means that the two rooftop transport paths extend substantially parallel to each other and adjacent to one another. Rooftop transport paths are not limited to those located at the same horizontal level and / or strictly parallel. The space between the first and second rooftop transport paths and / or the horizontal levels of the first and second rooftop transport paths can be adjusted according to the terrain. For clarity, the first and second rooftop transport paths are physically separated from each other. A path formed by the upper surfaces of a set of multiple beams does not have two parts.

[0111] like Figures 1 to 3 As illustrated in the variant, the first plurality of main beams 4 and the second plurality of main beams 5 formed by the main beam 6 can each be positioned on all the piers. Generally, the first plurality of main beams 4 and the second plurality of main beams 5 formed by the main beam 6 are positioned on all the piers when they extend laterally to each pier sufficient to support both the first plurality of main beams and the second plurality of main beams. Alternatively, the first plurality of main beams 4 and the second plurality of main beams 5 formed by the main beam 6 may be positioned on only a portion of the pier, for example, in the case where the pier is in the form of a column, wherein half of the pier supports the first plurality of main beams and the other half of the pier supports the second plurality of main beams.

[0112] Optionally, supports are positioned between the pier and the main beam. Supports are devices that support the main beam and transfer loads and movements from the main beam and superstructure to the substructure and foundation. Supports allow for controlled movement and reduce the stresses involved.

[0113] During the construction phase, thanks to the first plurality of main beams 4 formed by the main beams and the second plurality of main beams 5 formed by the main beams 6, vehicles circulating on the already positioned main beams can easily transport each additional component of the transport structure to its location along one roof-type transport path and return to the storage point along another roof-type transport path. Access to and from the ground along the construction route is no longer required. This advantage will be further detailed in the description of the erection method.

[0114] According to a variation, this part of the transport structure also includes a third plurality of beams formed by beams 6 positioned on the first plurality of beams 4 and / or a fourth plurality of beams formed by beams 6 positioned on the second plurality of beams 5. Specifically, each of the third plurality of beams is positioned on a beam of the first plurality of beams, and / or each of the fourth plurality of beams is positioned on a beam of the second plurality of beams. This positioning limits the footprint of the transport structure. This positioning also reduces the number of switches and facilitates surface use, particularly on surfaces biased towards the station.

[0115] The characteristics and variations of the main beams in the first and second main beams described above also apply to the main beams in the third and fourth main beams. All main beams in the multiple main beams can be identical to facilitate logistics.

[0116] Optionally, part 1 of the transport structure according to the invention does not include any platform, whether the platform is positioned on a pier or connected to a beam of a first or second roof-type transport path. The platform is defined as a lightweight structure suitable for vehicle traffic. The platform is preferably made of steel. The platform preferably includes a traffic deck, i.e., a surface suitable for vehicle traffic, which may be reinforced underneath by longitudinal and / or lateral stiffeners. These stiffeners increase the structural rigidity of the traffic deck. For safety reasons, the traffic deck may also include safety rails along the longitudinal edges of the traffic deck. The traffic deck, stiffeners, and safety rails are preferably made of steel. The traffic deck is preferably a perforated surface, such as perforated steel plate or metal grating.

[0117] Therefore, part 1 of the transport structure according to the invention does not include any service path formed by a plurality of platforms positioned along the longitudinal axis X. A service path refers to at least one continuous track designed to bear vehicle traffic. The service path differs from the transport path in that the service path is not designed to bear the transport of heavy components such as beams.

[0118] Reference Figures 4 to 9 The method for erecting part 1 of the transport structure according to the present invention will now be described.

[0119] exist Figure 4 In the first step illustrated, piers 3 of part 1 of the transport structure are erected. These piers can be erected using any suitable method, such as using panel formwork. The pier erection method includes erecting pier foundations according to the requirements of the ground properties. This step can be performed before, or at least partially concurrently with, the step of positioning the main beam 6. In other words, the piers can be erected before the main beam positioning begins, for example, several weeks before the main beam positioning begins. This specifically provides time for concrete drying and soil compaction. Alternatively, some piers may still be under construction when the main beam positioning begins on the first erected pier.

[0120] Since the area required for erecting piers is limited and only light vehicles (bulldozers, concrete mixers) are needed, piers are preferably erected by ground access to the construction point of each pier.

[0121] In the second step of erecting part 1 of the transport structure, the main beam 6 is erected.

[0122] As described above, the erection of the main beam begins at storage point 15, where at least a portion of the components of the transport structure are stored. Depending on the ease of transporting the components to the storage point, some components may be manufactured at the storage point within a manufacturing facility. This may be the case for large-scale components such as pipe sections, metal structures, or main beams. Manufacturing some components at the storage point minimizes the erection time at the construction point and allows for better control over the quality of the manufactured components.

[0123] Reserve point 15 is preferably located at a future point of the station, particularly a passenger station and / or freight station. This limits the land area required for the construction phase. It also limits civil engineering works. In particular, the civil engineering works completed for establishing the reserve point and its optional manufacturing facilities can be used for erecting the station. The reserve point is preferably located at ground level.

[0124] like Figure 5As illustrated, the first sub-step of erecting the main beam 6 is performed at the reserve point 15. This sub-step includes erecting a first section of the structure at the reserve point, the first section including at least one pier 3, a main beam 6 from a first plurality of main beams, and a main beam 6 from a second plurality of main beams. Specifically, this sub-step includes positioning the main beams from the first plurality of main beams on at least one pier and positioning the main beams from the second plurality of main beams on at least one pier. More specifically, the main beams from the first plurality of main beams and the main beams from the second plurality of main beams are positioned on the same at least one pier. This positioning is preferably accomplished using a crane 16, which can pick up the main beams from the reserve point and move them to the pier.

[0125] According to the first variation, the first section of the structure includes a single pier. This is especially true when the reserve point is located on higher ground. Then, the first end of the first beam of the first plurality of beams can rest on the higher ground, while its second end can rest on the downwardly positioned pier. Similarly, the first end of the first beam of the second plurality of beams can rest on the higher ground, while its second end can rest on the downwardly positioned pier. In this case, the first sub-step includes positioning the beams of the first plurality of beams between the higher ground and the pier, and positioning the beams of the second plurality of beams between the higher ground and the pier.

[0126] according to Figure 5 The second variation illustrated includes a first section of the structure comprising two piers. This is particularly true when the storage point is located on substantially flat ground. Then, the first end of the first beam of the first plurality of beams can rest on the first pier, and its second end can rest on the second pier. Similarly, the first end of the first beam of the second plurality of beams can rest on the first pier, and its second end can rest on the second pier. In this case, the first sub-step includes positioning the beams of the first plurality of beams on the two piers and positioning the beams of the second plurality of beams on the two piers.

[0127] This first sub-step may include erecting other sections of the structure at the reserve point. The number of sections erected at the reserve point is limited by the ability of the cranes at the reserve point to position the main beams on the piers.

[0128] Once the first section of the structure has been erected, the first section includes a first end portion adjacent to the storage point and a second end portion located at the opposite end of the first end portion. The first end portion of the first section corresponds to the first end portion of that part of the transport structure erected according to the invention. Therefore, the position of the first end portion of that part of the transport structure erected according to the invention will not change over time during the erection of that part of the transport structure. As for the second end portion of the first section, as long as no other section of the structure is erected downstream of the first section, the second end portion corresponds to the second end portion of the structure under construction. In other words, each time a new section is erected downstream of an already erected section of the transport structure, the position of the second end portion of the structure under construction will change over time.

[0129] Due to the various components constituting the erected structure, vehicle 17 can circulate on a first roof-type transport path 7 formed by at least one of the first plurality of main beams 4 and a second roof-type transport path 10 formed by at least one of the second plurality of main beams 5. In particular, vehicles moving components to be positioned along the construction route can circulate on the first roof-type transport path, that is, circulate from the first end of the structure under construction to the second end. Once the component reaches its usage position, the vehicle can return to the first end via the second roof-type transport path.

[0130] Therefore, in the second sub-step of erecting the main beam 6, another section of the structure can be erected as detailed below. For simplicity, this section will be referred to as the "second section" below, assuming that only the first section has already been erected at the reserve point.

[0131] The second section of the structure includes one of the first plurality of main beams 4, one of the second plurality of main beams 5, and at least one pier 3.

[0132] As explained above regarding the erection of piers, at least one additional pier is erected downstream of the first section of the structure.

[0133] Vehicle 17, suitable for transporting heavy components, is positioned on the first section of the structure, specifically on the first roof-type transport path 7, and more specifically on the first beam 6 of the first plurality of beams 4. The vehicle can be lifted by crane 16, or its position can be reached via access ramps or any other suitable equipment. The type of vehicle is not limited. The vehicle can be a wheeled vehicle, such as a truck or a train locomotive. Depending on the type of vehicle, the components to be transported can be loaded onto one vehicle or multiple vehicles simultaneously, or the vehicles can be simply attached to the components, as is possible in the case of a train locomotive used for transporting components equipped with railway wheels. In this specification, the terms "assembly" and "pairing" are used equivalently to refer to the loading of a vehicle with a component and the connection of a vehicle with a component. The term "disconnection" is used equivalently to refer to the unloading of a component from a vehicle and the disconnection of the vehicle from the component.

[0134] Some vehicles are equipped with the main beams of the second section of the structure. Specifically, the vehicle is equipped with one of the first plurality of main beams 4, and the vehicle is equipped with one of the second plurality of main beams 5, which is also a main beam 6. Components can be transported from a storage point onto the first section of the structure, or they can be lifted from the storage point onto the first section of the structure using a crane. In the first case, the component can be transported by the vehicle itself. In the second case, the vehicle can be positioned and then assembled.

[0135] Then, vehicles are used to transport these beams along the first roof-type transport path 7 from the first end of the structure under construction to the second end adjacent to the location where these beams will be used. Specifically:

[0136] - The main beam 6 of the first plurality of main beams 4 is transported along the first roof-shaped transport path 7 formed by the main beams of the first plurality of main beams that have been positioned on the piers.

[0137] - The beams 6 in the second plurality of beams 5 are transported along the first roof-type transport path 7, that is, along the same roof-type transport path as at least one beam 6 in the first plurality of beams.

[0138] The order in which the beams are paired with the vehicle and transported to the second end is not restricted. Furthermore, some beams may be transported to the second end while others remain mounted on the vehicle. If the beams in the first plurality of beams 4 and the beams in the second plurality of beams 5 are different in design, these beams are preferably transported alternately to the second end to facilitate their positioning.

[0139] Once the main beam has been delivered to the second end of the structure under construction, it is positioned at its service location, i.e., its service location within the structure. Specifically:

[0140] - One of the first plurality of main beams 4, beam 6, is positioned downstream of the first roof-type transport path 7. Specifically, beam 6 of the first plurality of main beams 4 is positioned after the main beam forming the second end of the structure under construction in the first roof-type transport path. More specifically, beam 6 of the first plurality of main beams 4 is positioned along the longitudinal axis X to coincide with the main beam 4 forming the second end of the first roof-type transport path 7. Even more specifically, beam 6 of the first plurality of main beams 4 is positioned such that the first end of the beam rests on a pier forming the second end of the first section of the structure, and the second end of the beam rests on at least one additional pier erected downstream of the first section of the structure. The main beam of the first plurality of main beams is preferably positioned using a crane 18, more preferably using a beam-laying crane supported by the structure itself.

[0141] Furthermore, beam 6 of the second plurality of main beams 5 is positioned downstream of the second roof-type transport path 10. Specifically, beam 6 of the second plurality of main beams 5 is positioned after the main beam forming the second end of the structure under construction on the second roof-type transport path. More specifically, beam 6 of the second plurality of main beams 5 is positioned along the longitudinal axis to coincide with the main beam forming the second end of the second roof-type transport path. Even more specifically, beam 6 of the second plurality of main beams 5 is positioned such that the first end of the beam rests on a pier forming the second end of the first section of the structure, and the second end of the beam rests on an additional pier erected downstream of the first section of the structure. The main beam of the second plurality of main beams is preferably positioned by a crane 18, more preferably by a beam releaser crane.

[0142] It is advantageous to use a crane 18 supported by a structure. The crane 18 further limits the footprint of the erection by eliminating the need for ground access to and from the construction site and for crane ground preparation. This also makes the erection method more independent of topography and terrain roughness.

[0143] The main beams are alternately positioned downstream of the first transport path 7 and the second transport path 10, more preferably by means of a main beam releaser crane. The order in which the main beams are alternately positioned is not limited. Furthermore, some main beams may be positioned while others remain paired with the vehicle or transported to the second end.

[0144] Once the main beam has been positioned, the corresponding detached vehicle can return to the first end of the structure along the second roof-type transport path 10. Specifically:

[0145] - The vehicle 17, detached from beam 6 in the first plurality of beams 4, moves from the first roof-type transport path 7 to the second roof-type transport path 10. The vehicle can be lifted and placed on the second roof-type transport path using a crane. Preferably, the vehicle is lifted using a beam-release crane.

[0146] - The vehicle 17, detached from beam 6 in the second plurality of beams 5, moves from the first roof-type transport path 7 to the second roof-type transport path 10. The vehicle can be lifted and placed on the second roof-type transport path using a crane. Preferably, the vehicle is lifted using a beam-releasing crane.

[0147] Once the second section of the structure has been erected as detailed above, the other sections of the structure can be erected one after another according to a similar process and as detailed below regarding the erection of the xth section of the structure.

[0148] The x-th segment of the structure includes: the nth beam 6 among the first plurality of beams 4, the nth beam 6 among the second plurality of beams 5, and at least the z-th pier 3. By default, x, z, and n are different. When each segment of the structure includes a single platform, x equals n and y. When the first segment includes 2 piers and each segment of the structure except the first segment includes a single pier, z equals n+1.

[0149] At least the z-th pier 3 has been erected downstream of the (x-1)th first section.

[0150] like Figure 6 As illustrated, vehicle 17, after detaching from the main beam of the preceding section of the structure and returning to the first end of the structure, is equipped with the main beam of the xth section of the structure. Specifically, the vehicle is equipped with at least the nth main beam among a first plurality of main beams, and the vehicle is equipped with the nth main beam among a second plurality of main beams.

[0151] like Figure 7 As illustrated, starting from the first end of the structure, a vehicle transports the main beam 6 of the xth segment of the structure along the first roof-type transport path 7 from the first end of the structure under construction to the second end adjacent to its intended use location. Specifically:

[0152] - The nth beam 6 of the first plurality of beams 4 is transported along the first roof-shaped transport path 7 formed by (n-1) of the first plurality of beams previously positioned on the pier.

[0153] - Transport the nth beam 6 of the second plurality of beams 5 along the first roof-type transport path 7, that is, along the same roof-type transport path as the nth beam in the first plurality of beams.

[0154] The order in which the main beams are paired with the vehicle and transported to the second end is not restricted. Furthermore, some main beams may be transported to the second end while others remain paired with the vehicle. If the main beams in the first plurality of main beams 4 and the main beams in the second plurality of main beams 5 are different in design, these main beams are preferably transported alternately to the second end to facilitate their positioning.

[0155] like Figure 8 and Figure 9 As illustrated, once the main beam is transported to the second end of the structure under construction, it is positioned in its intended use location. Specifically:

[0156] - The nth beam 6 of the first plurality of beams is positioned downstream of the first roof-type transport path 7. Specifically, the nth beam 6 of the first plurality of beams is positioned after the beam forming the second end of the structure under construction in the first roof-type transport path. More specifically, the nth beam 6 of the first plurality of beams is positioned to coincide with the (n-1)th beam of the first roof-type transport path along the longitudinal axis. Even more specifically, the nth beam 6 of the first plurality of beams is positioned such that the first end of the nth beam rests on the pier ((z-1)th pier) forming the second end, and the second end of the nth beam rests on the zth pier erected downstream of the structure. The nth beam of the first plurality of beams is preferably positioned using a crane 18, more preferably using a beam-releasing crane supported by the structure itself.

[0157] Furthermore, the nth beam 6 of the second plurality of beams 5 is positioned downstream of the second roof-type transport path 10. Specifically, the nth beam 6 of the second plurality of beams 5 is positioned after the beam forming the second end of the structure under construction in the second roof-type transport path. More specifically, the nth beam 6 of the second plurality of beams 5 is positioned to coincide with the (n-1)th beam of the second roof-type transport path along the longitudinal axis. Even more specifically, the nth beam 6 of the second plurality of beams 5 is positioned such that the first end of the nth beam rests on the pier forming the second end (the (z-1)th pier), and the second end of the nth beam rests on the zth pier erected downstream of the structure. In other words, the nth beam 6 of the second plurality of beams 5 is positioned next to the nth beam of the first plurality of beams. The nth beam of the second plurality of beams is preferably positioned using a crane 18, and more preferably using a beam releaser crane.

[0158] The main beams are alternately positioned downstream of the first transport path 7 and the second transport path 10, more preferably by means of a main beam releaser crane. The order in which the main beams of the xth section are alternately positioned is not limited. Furthermore, some main beams of the xth section may be positioned, while other main beams of the xth section or subsequent sections are paired with vehicles or transported to the second end section.

[0159] like Figure 8 and Figure 9 As illustrated, once the main beam of the xth segment of the structure has been positioned, the corresponding detached vehicle can return to the first end of the structure along the second roof-type transport path 10. Specifically:

[0160] - The vehicle that has detached from the nth beam in the first plurality of beams moves from the first roof-type transport path 7 to the second roof-type transport path 10.

[0161] - The vehicle that has detached from the nth beam in the second plurality of beams moves from the first roof-type transport path 7 to the second roof-type transport path 10.

[0162] The vehicle can be lifted and placed on the service path using a crane. Preferably, a beam-operated crane is used to lift the vehicle.

[0163] At the end of the erection phase, the last beam of the first plurality of beams and the last beam of the second plurality of beams are positioned on the last pier of the structure. These piers may be adjacent to or shared with the second part of the transport structure, which is being erected or is being erected as an extension of the relevant part of the transport structure along the longitudinal axis of the transport route. This second part of the transport structure is erected from a second reserve point, possibly located downstream of the relevant part at a future station. This second part of the transport structure is constructed by erecting the structure of the second part after the structure of the relevant part has been erected. In other words, each part is constructed from one reserve point to another, and at some point, the two parts are connected. Thus, the last beam of the first plurality of beams of the relevant part is adjacent to the last beam of the first plurality of beams of the second part, creating continuity in the first assembly formed by pipe section 14. Similarly, the last beam of the second plurality of beams of the relevant part is adjacent to the last beam of the second plurality of beams of the second part, creating continuity in the second assembly formed by pipe section 14.

[0164] Once all the sections of the transport structure are assembled one after another, an optional third plurality of beams 5 can be positioned on the first plurality of beams 4, particularly on the first roof-type transport path 7, and / or an optional fourth plurality of beams 5 can be positioned on the second plurality of beams 4, particularly on the second roof-type transport path 10.

[0165] Since the beams of the third and fourth tiers are positioned on top of the beams of the first and second tiers, respectively, and block the first and second roof-type transport paths, the assembly can be performed in reverse order of assembling the first and second tiers. In other words, the beams of the third and / or fourth tiers are first positioned at the second end of the structure under construction, and then positioned along the direction of the first end of the structure with one beam in front of another, i.e., one beam upstream of another. In this case, vehicles can be used to transport the beams of the third and / or fourth tiers from the first end of the structure to their intended use location along only one of the selected transport paths (first and second), and the vehicles return along the other transport path (first and second), as described above with reference to the first and second tiers.

[0166] Alternatively, the third and / or fourth girders are erected forward rather than backward. In this case, girder 6 of the third girders is transported by vehicle from the first end of the structure to its place of use via a roof-type transport path selected from the following: a third roof-type transport path formed by the girders of the third girders already positioned on the first roof-type transport path; and / or a second roof-type transport path; or, if any, a fourth roof-type transport path formed by the girders of the fourth girders already positioned on the second roof-type transport path. The vehicle returns via another transport path. Similarly, girder 6 of the fourth girders is transported by vehicle from the first end of the structure to its place of use via a roof-type transport path selected from the following: a fourth roof-type transport path formed by the girders of the fourth girders already positioned on the second roof-type transport path; and / or a first roof-type transport path; or, if any, a third roof-type transport path formed by the girders of the third girders already positioned on the first roof-type transport path. The vehicle returns via another transport path.

[0167] This assembly is similar to the assembly described above with reference to the first and second multiple beams.
