  • the modules 10 that make up such a plant 100 are equipped with multiple pieces of equipment for performing various types of fluid processing, as well as portions of large pieces of equipment that are divided into multiple pieces.
  • the modules 10 house these pieces of equipment within a frame structure made up of, for example, multiple supports and beams. For the sake of simplicity, individual illustrations and descriptions of these pieces of equipment are omitted for the modules 10 shown in the drawings of this application.
  • a number of beams (hereinafter also referred to as "bottom beams 11"; see also Figure 9) that make up the lower end of the module 10 each have a number of pedestals 12 formed on them that extend downward. These multiple pedestals 12 are arranged in a grid pattern on the bottom surface of the module 10, for example, at positions where the bottom beams 11 intersect. Each pedestal 12 is then placed on a number of pre-installed foundations 2 that protrude from the site S1, which is the installation area for the module 10, and then connected to one another. Therefore, when viewed in plan, the foundations 2 and pedestals 12 are arranged in the same array.
  • each figure is for the convenience of explaining the comparative embodiment and each embodiment, and may differ from the arrangement on the actual module 10. There are no particular limitations on the number or spacing of the pedestals 12 and foundations 2, as long as they are configured to be able to continue to stably support the module 10 on site S1 when connected to each other.
  • Modules 10 are transported onto site S1 via transport path S2 within plant 100 by multiple SPMTs (Self-Propelled Modular Transporters) 3, which are carts, and installed on foundations 2.
  • SPMTs Self-Propelled Modular Transporters
  • other modules and equipment are placed on both sides of transport path S2, making it difficult to transport plant 100 to site S1 via other routes.
  • Modules 10 are loaded across the loading platforms 31 of SPMTs 3, which are arranged in multiple rows (three rows in the example shown) with spaces between them, and are transported while still loaded onto these multiple SPMTs 3.
  • each pedestal 12 protruding downward from the lower end of the module 10 is positioned in the gap between adjacent rows of SPMTs 3 or on the outer side of the row of SPMTs 3 to avoid interference with the SPMTs 3.
  • the number of rows of SPMTs 3 and the number of SPMTs 3 per row are set appropriately depending on the weight of the module 10 and the bearing capacity of the site S1 and transport route S2.
  • the SPMT3 comprises a plate-shaped loading platform 31 that can be raised and lowered, and multiple wheels that are arranged below the loading platform 31 and support the loading platform 31 via support shafts.
  • the multiple sets of wheels are arranged in pairs across the width of the loading platform 31 and are arranged along the longitudinal direction of the loading platform.
  • each SPMT 3 When an operator operates these SPMTs using a controller, each SPMT 3 performs operations such as traveling and lifting/lowering the loading platform in sync with one another. This allows each SPMT 3 to transport the module 10 stably without any variation in operation.
  • the bottom and top surfaces of the rectangular parallelepiped module 10 transported by SPMT3 have significantly different aspect ratios.
  • the width of the transport path S2 and the surrounding area of the site S1 are sufficiently wide, the module 10 can be transported to the site S1 without having to worry about the longitudinal orientation of the bottom surface, etc.
  • Figures 1 and 2 are perspective and plan views illustrating the transport of module 10 to site S1 in a comparative embodiment.
  • the bold arrows in Figure 1 indicate part of the travel path of the illustrated module 10, and this is the same in the subsequent figures.
  • the aspect ratio of module 10 when viewed in plan is significantly different.
  • the travel direction is set so that the short side of module 10 passes within the path width of transport path S2 when viewed from above.
  • the transport path S2 is not limited to the ground through which the SPMT3 passes, but also includes the space above the ground where there are no other structures that may come into contact with the module 10.
  • the width of the transport path S2 may differ between the ground and the space above; for example, it may be relatively narrow on the ground and relatively wide in the space above, or vice versa. Even in these cases, as long as there is a path width at each height position of the transport path S2 that prevents the SPMT3 and module 10 from interfering with other modules and equipment on either side, the module 10 can pass through the transport path S2.
  • site S1 is positioned so that its long side extends along a direction that passes through transport path S2 and bends to the left (X direction in the figure).
  • SPMT3 in order to have SPMT3 enter site S1 and align its entry angle with the direction of site S1, SPMT3 must be rotated to the left from transport path S2 towards site S1 as it enters.
  • an adjacent area S3 is provided at the back of the site S1, viewed along the direction of travel of the SPMT3.
  • This adjacent area S3 is used as a waiting position (described below).
  • the area of the adjacent area S3 is smaller than the aforementioned turning area required for rotating the SPMT3.
  • the site S1 is divided into an interference area, in which foundations 2 are provided in positions that will interfere with the SPMT3 when each SPMT3 travels along a predetermined travel path, and a non-interference area, in which foundations 2 are provided in positions that will not interfere with the SPMT3.
  • non-interference foundations 21 foundations 2 provided in non-interference areas
  • interference foundations 22 foundations 2 provided in interference areas
  • the interference area refers to an area within site S1 where foundations 2 are located that are predicted to come into contact with any part of SPMT3, such as the wheels or body, when SPMT3 travels along a preset travel path.
  • the travel path is set to include the trajectory of SPMT3 travel within a normally acceptable error range. For this reason, not all of the interference foundations 22 installed in the interference area will necessarily be positioned to actually interfere with SPMT3 when it travels. Referring to the comparative example in Figure 2, it can be said that the interference area is set as the area into which SPMT3 turns immediately after entering site S1.
  • the non-interference area refers to the area within site S1 other than the interference area. Also, referring to Figure 2, the non-interference area can be said to be set in the area ahead in the direction of travel, after passing through the area where SPMT3 needs to rotate.
  • the interference foundation 22 is separated into an underground foundation 23, which is the underground portion that does not protrude from the ground of the site S1 within the interference area, and an upper foundation 24, which is the portion above it ( Figure 11).
  • the underground foundation 23 and upper foundation 24 are constructed at different times.
  • construction of the foundation 2 is carried out differently in the interference area and the non-interference area. That is, in the interference area, only the underground foundation 23 of the interference foundation 22 is constructed, and the upper foundation 24 that protrudes above the ground is not constructed. On the other hand, in the non-interference area, the non-interference foundation 21 is constructed, and the foundation 2 is completed (the process of constructing the foundation in the non-interference area).
  • a protective member is provided above the underground foundation 23 of the interference footing 22 to protect the underground foundation 23 when the SPMT 3 passes through.
  • a wooden protective member 42 for example, is placed underground, and a steel plate 41 is provided to cover this protective member 42 from above ( Figure 9).
  • the protective member 42 is carried, for example, by workers, and placed above the underground foundation 23.
  • the steel plate 41 is placed above the protective member 42, for example, using heavy machinery.
  • the steel plate 41 is placed so that its upper surface is, for example, roughly flush with the ground.
  • each SPMT3 is moved straight toward the non-interference area, entering along the gaps between the rows of non-interference foundations 21. Furthermore, as shown in Figure 5, as each SPMT3 is moved straight, the leading edge of each SPMT3 passes through the non-interference area and moves to a position where it reaches the adjacent area S3 (a process of waiting at a waiting position). In this way, by overrunning the site S1 so to speak and allowing the leading edge of the SPMT3 to reach the adjacent area S3, the trailing edge of the SPMT3 passes through the interference area and reaches the non-interference area. In this way, by setting the waiting position of the SPMT3 in an area that does not include the interference area, construction of the upper foundation 24 can be carried out without interfering with the modules 10 placed on the SPMT3.
  • the upper foundations 24 of the interference foundations 22 are constructed in the interference area after the SPMT 3 has passed (process of constructing foundations in interference areas).
  • the non-interference foundations 21 and interference foundations 22 are installed on site S1 at the same pitch and height as the foundation 2 shown in the comparative example.
  • each SPMT3 is moved back towards the interference area, and the module 10 is placed on the site S1.

  • each pedestal 12 of the module 10 is placed above the corresponding foundation 2.
  • each SPMT 3 is lowered to a preset height, each pedestal 12 is placed on the corresponding foundation 2 (non-interfering foundation 21, interfering foundation 22), and each foundation 2 is connected to each pedestal 12. After that, each SPMT 3 is moved outward from the area directly below the module 10 and removed from site S1.
  • construction of the interference foundation 22 (connection of the upper foundation 24 to the underground foundation 23) is carried out in the interference area after the SPMT 3 has passed.

Abstract

Le problème décrit par la présente invention est de fournir un procédé par lequel il est possible de construire une fondation d'un module végétal même sur des sites étroits et des itinéraires de transport. La solution selon l'invention porte sur un procédé de construction d'une fondation d'un module végétal d'une structure de cadre présentant une pluralité de colonnes. Une pluralité de fondations supportant respectivement la pluralité de colonnes sont disposées à distance les unes des autres sur un site où le module végétal doit être installé ; un chariot sur lequel le module végétal a été chargé se déplace à travers le site le long d'un trajet de déplacement prédéfini ; et certaines de la pluralité de fondations doivent être agencées à des emplacements qui interféreront avec le chariot. Pour un tel cas, le procédé comprend : une étape consistant à construire une fondation d'une zone de non-interférence dans laquelle la fondation qui n'interfère pas avec le chariot se déplaçant à travers le site doit être fournie ; ensuite, une étape consistant à amener le chariot à entrer dans le site le long du trajet de déplacement et à placer ledit chariot en attente à un emplacement de veille prédéfini comprenant le site ; et ensuite, une étape consistant à construire une fondation d'une zone d'interférence dans laquelle la fondation qui interférera avec le chariot doit être fournie.
