DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, an embodiment of a construction management system, a construction management program, and a construction management method for the pneumatic caisson construction method will be described with reference to FIGS. (Overall composition) As shown in Figure 1, the pneumatic caisson method is a construction method for constructing underground structures by gradually lowering a caisson 1, which is a rectangular, cylindrical, or oval tubular box, into the ground. The caisson 1 has a base slab 1A. The caisson 1 defines a work chamber 2 below the base slab 1A.

[0009] Compressed air is supplied to the work chamber 2. An excavator 4 for excavating the ground 3 is placed in the work chamber 2. The excavator 4 moves along rails 5 fixed to the underside of the base plate 1A, which is the ceiling surface of the work chamber 2.

[0010] A man shaft 6 and a material shaft 7 are provided above the bottom slab 1A. The man shaft 6 is used as a passageway for workers. The material shaft 7 is a path for moving a soil removal bucket 8, which is used to transport excavated soil, in and out of the work chamber 2.

[0011] The soil discharge bucket 8 is a cylindrical container with a bottom. The empty soil discharge bucket 8 is lowered from the ground to the work chamber 2 via the material shaft 7 by the bucket transport unit 9. The soil discharge bucket 8 lowered into the work chamber 2 is loaded with excavated soil by the excavator 4. The soil discharge bucket 8 loaded with excavated soil is then raised to the ground via the material shaft 7 by the bucket transport unit 9.

[0012] A ranging sensor 10 is placed in the work room 2. The ranging sensor 10 is attached, for example, to the ceiling surface of the work room 2. The ranging sensor 10 measures the distance from a predetermined position on the ceiling surface of the work room 2 to each object located within the work room 2 as point cloud data. One example of the ranging sensor 10 is a LiDAR (Light Detection And Ranging). The point cloud data acquired by the ranging sensor 10 can be used to acquire the surface shape of the ground 3.

[0013] An inclinometer 11 is placed in the caisson 1. The inclinometer 11 measures the inclination angle of the caisson 1 from a reference position. As an example, the inclinometer 11 is placed on the bottom slab 1A. The inclinometer 11 is a digital two-axis inclinometer that measures the inclination angle relative to a horizontal plane in each direction of two orthogonal axes in the horizontal plane.

[0014] A settlement meter 12 is placed in the caisson 1. The settlement meter 12 measures the depth of settlement from a reference position in the caisson 1. As an example, the settlement meter 12 is placed in the caisson 1 above the bottom slab 1A.

[0015] A remote control room 13 is also provided on the ground. A management device 20 is arranged in the remote control room 13. The management device 20 controls various devices used in the pneumatic caisson construction method. The management device 20 also includes a display unit 24 such as a display that allows workers to monitor the status inside the work room 2.

[0016] (Device configuration) As shown in Fig. 2, the excavator 4 placed in the work chamber 2 is equipped with a motion sensor 4A for measuring its own position and attitude within the work chamber 2. As an example, the motion sensor 4A measures the position and swing angle of the excavator 4 on the rail 5. The motion sensor 4A also measures the position coordinates of both ends of the cutting edge of the excavation bucket of the excavator 4. The motion sensor 4A may be a measuring instrument such as a potentiometer or rotary encoder that measures the amount of movement of each axis of the excavator 4.

[0017] The construction management system includes the above-mentioned management device 20. The management device 20 is configured to be able to communicate with the bucket transport unit 9 on the ground, the excavator 4 and distance measurement sensor 10 in the work chamber 2, and the inclinometer 11 and subsidence meter 12 attached to the caisson 1. The management device 20 includes a control unit 21, a memory unit 22, an input unit 23, and a display unit 24.

[0018] The control unit 21 functions as a control means composed of a CPU, RAM, ROM, etc. The control unit 21 executes a construction management program to function as an inclination acquisition unit 21A, a subsidence amount acquisition unit 21B, an action acquisition unit 21C, a shape acquisition unit 21D, an image creation unit 21E, etc.

[0019] The inclination acquisition unit 21A acquires inclination information from the inclinometer 11. The inclination information is data on the inclination angle of the caisson 1 from the reference attitude measured by the inclinometer 11. The inclination acquisition unit 21A acquires, as the inclination information, from the inclinometer 11 the measurement results of the inclination angle relative to the horizontal plane for each direction of two axes that are orthogonal in the horizontal plane.

[0020] The subsidence amount acquisition unit 21B acquires depth information from the subsidence meter 12. The depth information is data on the subsidence depth of the caisson 1 measured by the subsidence meter 12 from a reference position. The operation acquisition unit 21C acquires operation information of the excavator 4 from the operation sensor 4A. The operation information is data including the position coordinates of the excavator 4 on the rail 5 acquired by the operation sensor 4A and the position coordinates of the cutting edge of the excavation bucket of the excavator 4.

[0021] The shape acquisition unit 21D acquires shape information of the ground 3 in the workroom 2 from the distance measurement sensor 10. The shape information of the ground 3 is point cloud data measured by the distance measurement sensor 10. The shape acquisition unit 21D calculates the surface shape of the ground 3 from the point cloud data measured by the distance measurement sensor 10.

[0022] The image creation unit 21E creates a construction status image for managing the construction status in the pneumatic caisson construction method based on the inclination information and depth information of the caisson 1, the operation information of the excavator 4, and the shape information of the ground 3. The construction status image will be described in detail later.

[0023] The storage unit 22 is, for example, a non-volatile memory such as an HDD or SSD, but may also be a cloud server capable of storing various types of data. The storage unit 22 stores various types of information handled by the management device 20. For example, the storage unit 22 stores a construction management program. The storage unit 22 stores three-dimensional models of the caisson 1 and the excavator 4, etc., as data for the image creation unit 21E to create a construction status image.

[0024] The input unit 23 is a device that allows an operator to input various instructions and information to the management device 20, and includes, for example, a keyboard and a pointing device. The display unit 24 is a device that outputs various information handled by the management device 20, and is, for example, a display. The input unit 23 and the display unit 24 may be a touch panel display or the like.

[0025] (Image of construction status) Below, with reference to Figs. 3 to 5, the construction status images created by the image creation unit 21E will be described. The construction status images created by the image creation unit 21E are displayed on the display unit 24 of the remote control room 13. Workers in the remote control room 13 can understand the condition of the caisson 1 and the situation inside the work room 2 by checking the construction status images. Note that Figs. 3 to 5 show examples of construction status images that reflect the inclination state of the caisson 1. However, for the sake of convenience, the drawings only show the inclination state of the caisson 1 schematically, and therefore the degree of inclination of the caisson 1 depicted in the drawings does not necessarily match the actual degree of inclination.

[0026] 3, the image creation unit 21E creates a caisson posture management image 30 as an example of a construction status image. The caisson posture management image 30 is an image for managing the subsidence depth and inclination state of the caisson 1.

[0027] The caisson posture management image 30 includes a first caisson object 31A and a second caisson object 31B. The first caisson object 31A represents the state of the three-dimensional model of the caisson 1 as viewed from a first viewpoint opposite a vertical plane including the first axis direction D1. The second caisson object 31B represents the state of the three-dimensional model of the caisson 1 as viewed from a second viewpoint opposite a vertical plane including the second axis direction D2. The first axis direction D1 and the second axis direction D2 correspond to the two axes along which the inclinometer 11 measures inclination. In other words, the horizontal angle between the line of sight when viewing the three-dimensional model of the caisson 1 from the first viewpoint and the line of sight when viewing the three-dimensional model of the caisson 1 from the second viewpoint is 90 degrees.

[0028] The first caisson object 31A represents the inclination of the caisson 1 from the horizontal plane in the first axis direction D1. The second caisson object 31B represents the inclination of the caisson 1 from the horizontal plane in the second axis direction D2. The first caisson object 31A and the second caisson object 31B have shapes that correspond to the outer shape of the caisson 1.

[0029] The caisson posture management image 30 includes a depth scale 32 that indicates the subsidence depth of the caisson 1. The relative positions of the first caisson object 31A and the second caisson object 31B with respect to the depth scale 32 are set according to the depth information acquired by the subsidence amount acquisition unit 21B. Note that the caisson posture management image 30 may also display the results of soil investigations conducted by boring surveys along with the depth scale 32.

[0030] The caisson posture management image 30 includes a cutting edge installation height line L1 and a foundation tip line L2. The cutting edge installation height line L1 represents the base end position of the cutting edge of the caisson 1 at the start of excavation. The base end position of the cutting edge of the caisson 1 roughly corresponds to the underside of the base slab 1A of the caisson 1. The foundation tip line L2 represents the target position for the base end position of the cutting edge of the caisson 1.

[0031] The caisson posture management image 30 may include a first history object 33A and a second history object 33B that represent the state of the first caisson object 31A and the second caisson object 31B at any time from the start of excavation to the present. The first history object 33A and the second history object 33B are displayed in a state that allows them to be distinguished from the first caisson object 31A and the second caisson object 31B, for example, by being semi-transparent or by showing only outlines. In Figure 3, the first history object 33A and the second history object 33B represent the state of the first caisson object 31A and the second caisson object 31B at the start of excavation.

[0032] The image creation unit 21E creates a caisson posture management image 30 based on the three-dimensional model of the caisson 1 stored in the memory unit 22, the inclination information acquired by the inclination acquisition unit 21A, and the depth information acquired by the subsidence amount acquisition unit 21B.

[0033] In detail, the image creation unit 21E tilts the three-dimensional model of the caisson 1 in each of the first axis direction D1 and the second axis direction D2 based on the tilt information. Then, the image creation unit 21E displays the three-dimensional model of the tilted caisson 1 as viewed from a first viewpoint as a first caisson object 31A. Similarly, the image creation unit 21E displays the three-dimensional model of the tilted caisson 1 as viewed from a second viewpoint as a second caisson object 31B. At this time, the image creation unit 21E sets the relative positions of the first caisson object 31A and the second caisson object 31B with respect to the depth scale 32 based on the depth information. The image creation unit 21E performs the above processing at each predetermined time step, thereby updating the caisson posture management image 30 at each time step.

[0034] As shown in Fig. 4, the image creation unit 21E creates a first work chamber image 40 as an example of a construction status image. The first work chamber image 40 is an image for managing the excavation status within the work chamber 2. The first work chamber image 40 represents the field of view of the interior of the work chamber 2, which is represented using objects such as three-dimensional models arranged in three-dimensional space, as seen from a side perspective. The first work chamber image 40 includes a base slab object 41, a rail object 42, an excavator object 43, and a ground object 44.

[0035] The base slab object 41 is a three-dimensional model that schematically represents the base slab 1A of the caisson 1. The base slab object 41 may be a block-shaped model including a ceiling surface 41A that corresponds to the underside of the base slab 1A, or may be a surface model consisting of only the ceiling surface 41A. The base slab object 41 is displayed in an inclined state according to the inclination information acquired by the inclination acquisition unit 21A.

[0036] The rail object 42 is a three-dimensional model that schematically represents the rail 5 fixed to the underside of the base plate 1A. The rail object 42 is placed along the ceiling surface 41A of the base plate object 41. In other words, the rail object 42 is displayed in an inclined state in accordance with the inclination of the base plate object 41.

[0037] The excavator object 43 is a three-dimensional model that schematically represents the excavator 4. The excavator object 43 is placed along the ceiling surface 41A of the base plate object 41 via the rail object 42. In other words, the excavator object 43 is displayed in an inclined state in accordance with the inclination of the base plate object 41 and the rail object 42.

[0038] The excavator object 43 includes a main body 43A that moves along the rail object 42, and a bucket 43B connected to the main body 43A. In the excavator object 43, the position of the main body 43A relative to the rail object 42 and the position of the bucket 43B relative to the main body 43A are set according to the operation information of the excavator 4 acquired by the operation acquisition unit 21C.

[0039] The ground object 44 represents a three-dimensional schematic representation of the surface shape of the ground 3 in the workroom 2. The shape of the ground object 44 is set according to the shape information of the ground 3 acquired by the shape acquisition unit 21D. The ground object 44 may be a point cloud representing the surface shape of the ground 3 using point cloud data acquired by the distance measurement sensor 10. Alternatively, the ground object 44 may be a three-dimensional model created based on the point cloud data acquired by the distance measurement sensor 10.

[0040] The image creation unit 21E creates a first work chamber interior image 40 based on the inclination information acquired by the inclination acquisition unit 21A, the operation information of the excavator 4 acquired by the operation acquisition unit 21C, and the shape information of the ground 3 acquired by the shape acquisition unit 21D.

[0041] In detail, the image creation unit 21E reads the three-dimensional models of the caisson 1, the excavator 4, and the rails 5 stored in the memory unit 22. Then, the image creation unit 21E sets the inclination angles for the base slab object 41, the rail object 42, and the excavator object 43 according to the inclination information acquired by the inclination acquisition unit 21A. Furthermore, the image creation unit 21E sets the position and rotation angle of the main body unit 43A relative to the rail object 42, and the position of the bucket unit 43B relative to the main body unit 43A, based on the operation information of the excavator 4 acquired by the operation acquisition unit 21C. In addition, the image creation unit 21E sets the shape of the ground object 44 based on the shape information of the ground 3 acquired by the shape acquisition unit 21D. The image creation unit 21E executes the above processing at each predetermined time step, thereby updating the first work chamber interior image 40 at each time step.

[0042] 4 illustrates the first workroom interior image 40 as viewed from a first viewpoint that faces a vertical plane including the first axis direction D1, but the viewpoint in the first workroom image 40 may be configured to be positionable at any position. For example, the viewpoint in the first workroom image 40 may be configured to be movable so as to describe a circular orbit within a horizontal plane, with the horizontal center of the base plate object 41 as the center.

[0043] Furthermore, the image creation unit 21E may simultaneously display, on the display unit 24, in addition to the first work chamber interior image 40 as seen from the first viewpoint, the first work chamber interior image 40 as seen from a second viewpoint opposite to a vertical plane including the second axis direction D2. The image creation unit 21E may display, on the display unit 24, the first work chamber interior image 40 in a state that reproduces the first-person viewpoint of an operator aboard the excavator 4.

[0044] 5, the image creation unit 21E creates a second work chamber image 50 as an example of a construction status image. The second work chamber image 50 is an image for managing the excavation status inside the work chamber 2, similar to the first work chamber image 40. The second work chamber image 50 represents in two dimensions the field of view of the interior of the work chamber 2 as seen from above, represented using objects such as three-dimensional models.

[0045] The second work chamber image 50 includes a ground object 51, a rail object 52, an excavator object 53, and a bubble object 54. As an example, the second work chamber image 50 includes two sets of rail objects 52 and excavator objects 53.

[0046] The ground object 51 schematically represents on a plane the surface shape of the ground 3 inside the workroom 2 as viewed from above. For example, the ground object 51 represents the unevenness of the surface of the ground 3 by using a heat map that displays the ground 3 in different colors depending on its height, contour lines that connect points of the same height on the surface shape of the ground 3, or a combination of these.

[0047] For example, the ground object 51 may be a heat map composed of a point cloud in which colors correspond to the height of the ground 3, using point cloud data acquired by the distance measurement sensor 10. In this case, the height of the ground 3 can be the vertical distance from a virtual horizontal plane located at an arbitrary reference depth to each point constituting the point cloud. In other words, the ground object 51 represents the difference in elevation of the surface of the ground 3 in the vertical direction.

[0048] The rail object 52 represents, in a planar view, the rails 5 fixed to the underside of the base 1A as viewed from above. The excavator object 53 represents, in a planar view, the excavator 4 attached to the rails 5 as viewed from above. The rail object 52 and the excavator object 53 are displayed superimposed on the ground object 51.

[0049] The excavator object 53 includes a main body 53A that moves along the rail object 52, and a bucket 53B connected to the main body 53A. In the excavator object 53, the position of the main body 53A relative to the rail object 52 and the position of the bucket 53B relative to the main body 53A are set according to the operation information of the excavator 4 acquired by the operation acquisition unit 21C.

[0050] The bubble object 54 is an object that imitates an air bubble when a level with a bubble tube is used to measure the inclination of the caisson 1. In other words, the bubble object 54 represents the inclination state of the caisson 1.

[0051] For example, the second workroom interior image 50 includes a first auxiliary line 55 extending along the first axis direction D1 and a second auxiliary line 56 extending along the second axis direction D2. The first auxiliary line 55 and the second auxiliary line 56 pass through a reference point P1 located at the center of the ground object 51 in the second workroom interior image 50. Note that the reference point P1 may be located at any position in the second workroom interior image 50.

[0052] The distance from the reference point P1 to the bubble object 54 represents the magnitude of the tilt angle of the caisson 1. Furthermore, the direction of the bubble object 54 as viewed from the reference point P1 represents the tilt direction of the caisson 1. In other words, the distance from the reference point P1 to the bubble object 54 and the direction of the bubble object 54 as viewed from the reference point P1 are set according to the tilt information acquired by the tilt acquisition unit 21A.

[0053] For example, the bubble object 54 is positioned so as to be biased upward from the reference point P1 based on the state of inclination of the caisson 1 in each of the first axis direction D1 and the second axis direction D2. In this case, the closer the base 1A of the caisson 1 is to horizontal, the shorter the distance from the reference point P1 to the bubble object 54. On the other hand, the greater the inclination angle of the caisson 1, the greater the distance from the reference point P1 to the bubble object 54.

[0054] The image creation unit 21E creates a second work chamber interior image 50 based on the inclination information acquired by the inclination acquisition unit 21A, the operation information of the excavator 4 acquired by the operation acquisition unit 21C, and the shape information of the ground 3 acquired by the shape acquisition unit 21D.

[0055] In detail, the image creation unit 21E sets a heat map as the ground object 51 based on the shape information of the ground 3 acquired by the shape acquisition unit 21D. Then, the image creation unit 21E displays the rail object 52 and the excavator object 53 superimposed on the ground object 51. At this time, the image creation unit 21E sets the position of the main body part 53A relative to the rail object 52 and the position of the bucket part 53B relative to the main body part 53A based on the operation information of the excavator 4 acquired by the operation acquisition unit 21C. Then, the image creation unit 21E sets the position of the bubble object 54 relative to the reference point P1, i.e., the distance and direction from the reference point P1 to the bubble object 54, according to the tilt information acquired by the tilt acquisition unit 21A. The image creation unit 21E executes the above processing at each predetermined time step, thereby updating the second work chamber interior image 50 at each time step.

[0056] (Effects of the embodiment) (1) The first work chamber image 40 and the second work chamber image 50 include excavator objects 43, 53 corresponding to operation information of the excavator 4, and ground objects 44, 51 corresponding to shape information of the ground 3. A worker in the remote control room 13 can understand the state of the ground 3 in the work chamber 2 and the operation status of the excavator 4 from the states of the excavator objects 43, 53 and the ground objects 44, 51. Furthermore, the first work chamber image 40 and the second work chamber image 50 reflect inclination information that indicates the inclination state of the caisson 1. Therefore, by checking the first work chamber image 40 and the second work chamber image 50, a worker in the remote control room 13 can efficiently understand both the excavation status in the work chamber 2 and the inclination state of the caisson 1.

[0057] (2) The first workroom interior image 40 includes a base slab object 41 that is inclined according to the inclination information acquired by the inclination acquisition unit 21A. Furthermore, in the first workroom interior image 40, an excavator object 43 is arranged along the base slab object 41. That is, the first workroom interior image 40 includes the base slab object 41 and the excavator object 43 that are inclined according to the inclination information. The worker in the remote control room 13 can understand the state of inclination of the caisson 1 from the state of inclination of the base slab object 41 and the excavator object 43 included in the first workroom interior image 40.

[0058] (3) The second work chamber interior image 50 includes a bubble object 54 that changes its distance and direction from the reference point P1 according to the inclination information acquired by the inclination acquisition unit 21A. The worker in the remote control room 13 can understand the inclination state of the caisson 1 from the position of the bubble object 54 included in the second work chamber interior image 50.

[0059] (4) The caisson posture management image 30 includes a first caisson object 31A and a second caisson object 31B, which are three-dimensional models of the caisson 1, and a depth scale 32 that indicates the subsidence depth of the caisson 1. The relative positions of the first caisson object 31A and the second caisson object 31B with respect to the depth scale 32 are set according to the depth information acquired by the subsidence amount acquisition unit 21B. Furthermore, the first caisson object 31A and the second caisson object 31B are displayed in an inclined state according to the inclination information acquired by the inclination acquisition unit 21A. A worker in the remote control room 13 can understand the subsidence depth and inclination state of the caisson 1 from the state of the first caisson object 31A and the second caisson object 31B included in the caisson posture management image 30.

[0060] (5) Since the first work chamber image 40 and the second work chamber image 50 include rail objects 42, 52, it becomes easier for a worker checking the first work chamber image 40 and the second work chamber image 50 to understand the range of motion of the excavator objects 43, 53.

[0061] (Example of change) The above embodiment can be modified as follows: The following modifications can be implemented in combination with each other within the scope of technical compatibility.

[0062] The image creation unit 21E may be configured to display any one of the multiple construction status images exemplified in the embodiment on the display unit 24. In this case, the image creation unit 21E may be configured to switch the construction status image displayed on the display unit 24 in response to an input from the worker. Furthermore, the image creation unit 21E may simultaneously display the multiple construction status images exemplified in the embodiment on the display unit 24.

[0063] For example, the image creation unit 21E may simultaneously display on the display unit 24 the caisson posture management image 30 and at least one of the first work chamber interior image 40 and the second work chamber image 50. In this case, by checking the display unit 24, the worker in the remote control room 13 can grasp the overall excavation status within the work chamber 2, the inclination state of the caisson 1, and the subsidence depth of the caisson 1. Furthermore, for example, the image creation unit 21E may simultaneously display on the display unit 24 four images: the caisson posture management image 30, the first work chamber interior image 40 as seen from the first viewpoint, the first work chamber interior image 40 as seen from the second viewpoint, and the second work chamber interior image 50.

[0064] The image creation unit 21E may be configured to have a function of creating at least one of the first work chamber interior image 40 and the second work chamber image 50 among the multiple construction status images exemplified in the embodiment. In this case, the image creation unit 21E may display an object indicating the numerical value of the subsidence depth in the first work chamber interior image 40 or the second work chamber image 50.

[0065] In the first work room interior image 40 and the second work room interior image 50, the rail objects 42, 52 may be omitted. The work chamber images for managing the excavation status in the work chamber 2 are not limited to the examples of the first work chamber image 40 and the second work chamber image 50. The work chamber images may be images that include objects corresponding to the excavator objects 43, 53 according to the operation information and the ground objects 44, 51 according to the shape information, and that reflect the slope information.
