Description

[Technical Field]

[0001] The present invention relates to a method, an apparatus, and a program for managing as-built condition when, for example, road pavement repair work is carried out. [Background technology]

[0002] Traditionally, road pavement repair work has been carried out when damage such as cracks occurs on the surface of the asphalt pavement that makes up the surface layer of a road. Asphalt road pavement repair work may involve, for example, forming a cutting layer by cutting to a specified depth, laying a base layer on top of the cutting layer, and then laying a surface layer on top of the base layer. When carrying out pavement repair work such as cutting overlay work or overlay work, it is necessary to manage the finished shape of the base and surface layers in terms of thickness, width, and extension (length).

[0003] Conventionally, a common method for managing the thickness of the base and surface layers is to use a level line stretched over the road (see, for example, Patent Document 1). In this method, a level line is stretched above the cut area, and the distance (drop-off amount) from this level line to the cut surface or base layer is measured, and the as-built management of the base layer thickness is carried out based on the measured drop-off amount. Note that as-built management of the surface layer thickness is also carried out in a similar manner. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2020-84521 Summary of the Invention [Problem to be solved by the invention]

[0005] However, conventional methods for managing the finished thickness of each layer are extremely cumbersome and involve a large amount of work, such as installing and relocating the level strings and measuring the amount of sagging. Furthermore, when level strings are used, accuracy is extremely low due to errors caused by slack in the level strings and errors associated with visually estimating the amount of sagging.

[0006] Therefore, the present invention has been made with an eye on such problems, and aims to provide a work-product management method, work-product management device, and work-product management program that require little work and high accuracy. [Means for solving the problem]

[0022] Hereinafter, an as-built management method, an as-built management device, and an as-built management program according to an embodiment of the present invention will be described with reference to the drawings.

[0023] The finished product management system 1 according to an embodiment of the present invention includes a total station 2 installed at a known point (e.g., a reference point), a prism 3 used together with the total station 2, and a terminal device 5 as a finished product management device.

[0024] The total station 2 acquires the three-dimensional coordinates of each point on the road surface relative to a known point. The prism 3 is a remote catcher and is connected to the total station 2 wirelessly.

[0025] Therefore, when measurements are taken using a total station 2, the total station 2 emits distance measurement light toward a prism 3 installed by an operator at each point on the road surface, receives the light reflected by the prism 3, and obtains the three-dimensional coordinates of each point relative to a known point based on the number of times the light wave oscillates between emission and reception.

[0026] The terminal device 5 is a portable information terminal having a display screen 5a, and is wirelessly connected to the total station 2. Therefore, when the total station 2 acquires the three-dimensional coordinates of each point, the three-dimensional coordinates are supplied from the total station 2 to the terminal device 5.

[0027] 2, the terminal device 5 can be wirelessly connected to a personal computer 6, and various data are supplied from the personal computer 6 to the terminal device 5. For example, when pavement repair work is carried out in which a surface course and a base course are laid, the various data includes design surface data for the surface course surface, design thicknesses of each layer, and the like.

[0028] The design surface data for the surface layer is 3D design data (3D TIN model) in LAND-XML format, and includes 3D data for any point on the road surface. Therefore, pavement repair work is carried out based on the design surface data for each layer, which is created based on the design surface data for the surface layer, and the design thickness of each layer.

[0029] In this embodiment, a case will be described in which pavement repair work is carried out in a pavement planning range (the range surrounded by dotted lines in Fig. 3) numbered 0 to 5, which are assigned every 20 m on the road, as shown in Fig. 3. Fig. 4(a) shows a cross section along the extension direction of the road after the pavement repair work has actually been carried out (cross section along line a1-a1 in Fig. 3), and Fig. 4(b) shows a cross section along the width direction of the road after the pavement repair work has actually been carried out (cross section along line a2-a2 in Fig. 3).

[0030] As shown in Figure 3, actual pavement repair work is generally carried out on a pavement repair area that is wider than the planned pavement area (the area surrounded by a solid line in Figure 3). As shown in Figure 3, the planned pavement width is A (mm) and the planned pavement length is C (mm).

[0031] In the pavement repair work of this embodiment, the road surface is cut in the pavement repair area to form a cutting layer as shown in Figure 5(a), a base layer is laid on top of the cutting layer as shown in Figure 5(b), and a top layer is laid on top of the base layer as shown in Figure 5(c). As shown in Figures 4(a) and 4(b), the design thickness (planned thickness) of the top layer is T1 (mm), and the design thickness (planned thickness) of the base layer is T2 (mm).

[0032] The terminal device 5 is configured with, for example, a microcomputer, and includes a CPU, a ROM storing a completed work management program that controls the operation of the terminal device 5 as a completed work management device, and a RAM that temporarily stores data used when executing the completed work management program. The completed work management program of this embodiment works in cooperation with hardware resources to construct specific information processing or its operating method according to completed work management (purpose of use).

[0033] As shown in Figure 2, the terminal device 5 has a design data receiving unit 10, a first position data receiving unit 11, a first calculation unit 12, a second position data receiving unit 13, a second calculation unit 14, a pavement thickness calculation unit 15, a management table creation unit 16, a pavement width calculation unit 17, a design data memory unit 18, a position data memory unit 19, and a display control unit 30.

[0034] The terminal device 5 has a display screen 5a and is connected to the total station 2 and the personal computer 6 wirelessly.

[0035] The design data receiving unit 10 receives various design data supplied from the personal computer 6. Specifically, the design data receiving unit 10 receives design surface data for the cutting layer, base layer, and surface layer, and design thickness data for the cutting layer and base layer.

[0036] The design surface data for the surface layer is design surface data of the surface layer surface to be used when pavement repair work is carried out, and is separately supplied to the PC 6. The design surface data for the surface layer is data showing the planned surface of the pavement repair work, and includes three-dimensional data of each point on the surface of the surface layer after the pavement repair work has been carried out, i.e., (x coordinate, y coordinate) showing the plan position and (z coordinate) showing the elevation (height).

[0037] The design surface data for the base layer is created by moving the design surface data for the surface layer directly downward by the design thickness of the surface layer using the personal computer 6. In this embodiment, the design thickness of the surface layer is T1, so the design surface data for the base layer is created by lowering the height of each point in the design surface data for the surface layer by the height of T1.

[0038] Similarly, the design surface data for the cutting layer is created by using the personal computer 6 to move the design surface data for the surface layer directly downward by the amount of the design thickness of the surface layer and base layer. In this embodiment, the design thickness of the surface layer is T1, and the design thickness of the base layer is T2, so the design surface data for the cutting layer is created by lowering the height of each point in the design surface data for the surface layer by the height of T1 + T2. Note that the design surface data for the cutting layer can also be created by using the personal computer 6 to move the design surface data for the base layer directly downward by the amount of the design thickness of the base layer.

[0039] The design thickness data for the cutting layer, base layer and surface layer were separately supplied to the personal computer 6.

[0040] When a base layer is laid above the cutting layer, the first position data receiving unit 11 receives three-dimensional coordinates of each point on the surface of the cutting layer measured by the total station 2 when the surface of the cutting layer is exposed. Also, when a top layer is laid above the base layer, the first position data receiving unit 11 receives three-dimensional coordinates of each point on the surface of the base layer measured by the total station 2 when the surface of the base layer is exposed.

[0041] When a base layer is laid above the cutting layer, the first calculation unit 12 calculates the difference between the current elevation and the reference elevation for each point on the surface of the cutting layer based on the three-dimensional coordinates for each point on the surface of the cutting layer measured by the total station 2 and the three-dimensional coordinates for each point included in the design surface data for the cutting layer. The reference elevation for each layer is the elevation (height) specified by the three-dimensional coordinates for each point included in the design surface data for each layer.

[0042] In addition, when a surface layer is laid above the base layer, the first calculation unit 12 calculates the difference between the current height and the reference height for each point on the surface of the base layer based on the three-dimensional coordinates of each point on the surface of the base layer measured by the total station 2 and the three-dimensional coordinates of each point included in the design surface data for the base layer.

[0043] When a base layer is laid above the cutting layer, the second position data receiving unit 13 receives three-dimensional coordinates of each point on the surface of the base layer measured by the total station 2 when the surface of the base layer is exposed. Also, when a surface layer is laid above the base layer, the second position data receiving unit 13 receives three-dimensional coordinates of each point on the surface of the surface layer measured by the total station 2 when the surface of the surface layer is exposed.

[0044] When a base layer is laid above the cutting layer, the second calculation unit 14 calculates the difference between the current height and the reference height for each point on the surface of the base layer based on the three-dimensional coordinates of each point on the surface of the base layer measured by the total station 2 and the three-dimensional coordinates of each point included in the design surface data for the base layer.

[0045] In addition, when a surface layer is laid above the base layer, the second calculation unit 14 calculates the difference between the current height and the reference height of each point based on the three-dimensional coordinates of each point on the surface of the surface layer measured by the total station 2 and the three-dimensional coordinates of each point included in the design surface data for the surface layer.

[0046] When a base layer is laid above the cutting layer, the pavement thickness calculation unit 15 calculates the elevation difference from the design thickness of the base layer based on the elevation difference from the reference elevation of each point calculated by the first calculation unit 12 and the difference from the reference elevation of each point calculated by the second calculation unit 14, and calculates the pavement thickness of the base layer by adding the elevation difference to the design thickness of the base layer.

[0047] In addition, when a surface layer is laid above the base layer, the pavement thickness calculation unit 15 calculates the elevation difference from the design thickness of the surface layer based on the elevation difference from the reference elevation of each point calculated by the first calculation unit 12 and the difference from the reference elevation of each point calculated by the second calculation unit 14, and calculates the pavement thickness of the surface layer by adding the elevation difference to the design thickness of the surface layer.

[0048] The as-built form management table creation unit 16 creates an as-built form management table for the base layer thickness when a base layer is laid above the cutting layer. Also, the as-built form management table creation unit 16 creates an as-built form management table for the surface layer thickness when a surface layer is laid above the base layer. The as-built form management table for each layer contains, for example, the elevation difference from the reference elevation of each point calculated by the first calculation unit 12, the difference from the reference elevation of each point calculated by the second calculation unit 14, the elevation difference from the design thickness, the design thickness, and the pavement thickness.

[0049] When the surface of the cutting layer is revealed, the pavement width calculation unit 17 calculates the widthwise distance between one end and the other end of the pavement repair area based on the three-dimensional coordinates of each point on the surface of the cutting layer measured by the total station 2.

[0050] In addition, when the surface of the base layer is exposed, the pavement width calculation unit 17 calculates the widthwise distance between one end and the other end of the pavement repair area based on the three-dimensional coordinates of each point on the surface of the base layer measured by the total station 2.

[0051] In addition, when the surface of the surface layer is exposed, the pavement width calculation unit 17 calculates the widthwise distance between one end and the other end of the pavement repair area based on the three-dimensional coordinates of each point on the surface of the surface layer measured by the total station 2.

[0052] In this way, the pavement width calculation unit 17 calculates the widthwise distance between one end and the other end of the pavement repair area in a cross section along the width direction of each layer.

[0053] The design data storage unit 18 stores various types of design data received by the design data receiving unit 10.

[0054] The position data storage unit 19 stores the position data received by the position data receiving unit 11 .

[0055] The display control unit 30 controls the content displayed on the display screen 5a. For example, the display control unit 30 displays the three-dimensional coordinates of each point measured by the total station 2, and displays the as-built form management table created by the as-built form management table creation unit 16.

[0056] The display control unit 30 also displays the roads around the start and end points of the paving plan area based on the design surface data of each layer, and displays the positions of the start and end points of the paving plan area. Note that when the roads around the start and end points of the paving plan area are displayed on the display screen 5a and a measurement is made at a predetermined point in the displayed area by the total station 2, the display control unit 30 displays the measurement position on the display screen 5a.

[0057] Furthermore, the display control unit 30 displays information indicating that each layer has been laid at the start and end points based on the current position data of the start and end points of the paving plan area for each layer. The information indicating that each layer has been laid at the start and end points is, for example, the elevation (height) included in the current position data of the start and end points of the paving plan area for each layer.

[0058] (Thickness control) The procedure for performing as-built management of the surface layer thickness and base layer thickness in the as-built management system 1 will be described with reference to Figs.

[0059] The management of the surface layer thickness and base layer thickness means managing whether the surface layer and base layer are laid to the appropriate thickness in accordance with the design surface data and design thickness.

[0060] In step S1, the design surface data for the surface layer when the pavement repair work is carried out is acquired. When ICT work is carried out, the design surface data for the surface layer is always created to be submitted to the client. Therefore, even if it is not created when the pavement repair work is carried out, the data created during the ICT work can be used.

[0061] In step S2, design surface data of the cutting layer and design surface data of the base layer are created based on the design surface data of the surface layer.

[0062] In step S3, the design surface data of the cutting layer and the design surface data of the base layer created in step S2 are input from the personal computer 6 to the terminal device 5. The control unit 5C of the terminal device 5 receives the design surface data of the cutting layer and the design surface data of the base layer at the design data receiving unit 10, and then stores them in the design data storage unit 17.

[0063] In step S4, as shown in Figure 4(a), the road pavement repair area is cut to the design thickness of the surface and base layers based on the design surface data of the cutting layer, so that the cutting layer is exposed in the road pavement repair area.

[0064] In step S5, the three-dimensional coordinates of each point on the cutting layer surface are measured by the total station 2. That is, the worker sets up the total station 2 near the road pavement repair area, and uses the total station 2 to emit distance measurement light toward the prisms 3 installed at each point on the cutting layer surface, thereby measuring the three-dimensional coordinates of each point.

[0065] In step S6, when the three-dimensional coordinates of each point on the cutting layer surface measured in step S5 are input from the total station 2 to the terminal device 5, the control unit 5C of the terminal device 5 accepts the three-dimensional coordinates of each point on the cutting layer surface in the position data accepting unit 11, and then stores them in the position data memory unit 18.

[0066] In step S7, the control unit 5C of the terminal device 5 calculates the difference in elevation between the current elevation and the reference elevation for each point on the cutting layer surface.

[0067] Figure 9 is a schematic diagram of a cross section along the width direction of a road in the pavement repair area where the cutting layer surface is exposed. CL in the figure indicates the center of the road, L2 indicates the left edge of the road, L1 indicates the midpoint between the left edge and the center of the road, R2 indicates the right edge of the road, and R1 indicates the midpoint between the right edge and the center of the road. The same applies to the following figures.

[0068] Figure 9 shows a case where the current surface data of the cutting layer is lower in elevation than the design surface data of the cutting layer. This means that the worker cut the road surface based on the design surface data of the cutting layer, but cut it until the elevation became lower than the design surface data.

[0069] The difference in elevation between the current height of the cutting layer and the reference height is -a1 (mm) for L2, -a2 (mm) for L1, -a3 (mm) for CL, -a4 (mm) for R1, and -a5 (mm) for R2. Note that a1 to a5 are positive numbers.

[0070] In step S8, as shown in Figure 5(b), the base layer is laid above the cut layer to its design thickness based on the base layer design surface data in the road pavement repair area, so that the base layer is exposed in the road pavement repair area.

[0071] In step S9, the three-dimensional coordinates of each point on the base layer surface are measured by the total station 2. That is, the worker installs the total station 2 near the road pavement repair area, and uses the total station 2 to emit distance measurement light toward the prisms 3 installed at each point on the base layer surface, thereby measuring the three-dimensional coordinates of each point.

[0072] In step S10, when the three-dimensional coordinates of each point on the base layer surface measured in step S9 are input from the total station 2 to the terminal device 5, the control unit 5C of the terminal device 5 accepts the three-dimensional coordinates of each point on the base layer surface in the position data accepting unit 11, and then stores them in the position data memory unit 18.

[0073] In step S11, the control unit 5C of the terminal device 5 calculates the difference in altitude between the current height of the base layer and the reference height for each point on the base layer surface.

[0074] Figure 10 is a schematic diagram of a cross section along the width direction of a road after the base layer has been laid in the pavement repair area. Figure 10 shows a case where the current surface data of the base layer is at a higher elevation than the design surface data of the base layer. In other words, this means that the worker laid the base layer based on the design surface data of the base layer, but the elevation ended up being higher than the design surface data.

[0075] The difference in elevation between the current height of the base layer and the reference height is +b1 (mm) for L2, +b2 (mm) for L1, +b3 (mm) for CL, +b4 (mm) for R1, and +b5 (mm) for R2. Note that b1 to b5 are positive numbers.

[0076] In step S12, the control unit 5C of the terminal device 5 adds up the elevation differences calculated in steps S7 and S11 to calculate the elevation difference between the pavement thickness of the actually laid base layer and the design thickness of the base layer. As shown in Fig. 11, the elevation difference from the design thickness of the base layer is a1 + b1 (mm) for L2, a2 ​​+ b2 (mm) for L1, a3 + b3 (mm) for CL, a4 + b4 (mm) for R1, and a5 + b5 (mm) for R2.

[0077] In step S13, the control unit 5C of the terminal device 5 calculates the pavement thickness of the actually laid base layer by adding the elevation difference calculated in step S12 to the design thickness of the base layer. As shown in Fig. 11, the pavement thickness of the base layer is a1 + b1 + T1 (mm) for L2, a2 ​​+ b2 + T1 (mm) for L1, a3 + b3 + T1 (mm) for CL, a4 + b4 + T1 (mm) for R1, and a5 + b5 + T1 (mm) for R2.

[0078] In step S14, the control unit 5C of the terminal device 5 creates a completed form management table of the thickness of the actually laid base layer, as shown in FIG.

[0079] In this embodiment, the pavement thicknesses at five locations, L2, L1, CL, R1, and R2, at cross sections along the width direction are managed at predetermined distance intervals (for example, every 40 meters) along the extension direction of the road pavement repair area. Furthermore, in this embodiment, as will be described in detail later, in order to manage the as-built shape of the extension (length) of the road pavement planning area, the pavement thicknesses at five locations, L2, L1, CL, R1, and R2, at cross sections along the width direction are also managed at the start and end points of the road pavement repair area.

[0080] In step S15, as shown in Figure 4(c), the surface layer is laid above the base layer to its design thickness based on the design surface data for the surface layer in the road pavement repair area, so that the surface layer is exposed in the road pavement repair area.

[0081] In step S16, the three-dimensional coordinates of each point on the surface of the surface layer are measured by the total station 2. That is, the worker installs the total station 2 near the area of ​​the road to be repaired, and uses the total station 2 to emit distance measurement light toward the prisms 3 installed at each point on the surface of the surface layer, thereby measuring the three-dimensional coordinates of each point.

[0082] In step S17, when the three-dimensional coordinates of each point on the surface of the surface measured in step S16 are input from the total station 2 to the terminal device 5, the control unit 5C of the terminal device 5 accepts the three-dimensional coordinates of each point on the surface of the surface in the position data accepting unit 11, and then stores them in the position data memory unit 18.

[0083] In step S18, the control unit 5C of the terminal device 5 calculates the difference in elevation between the current elevation of the surface layer and the reference elevation for each point on the surface of the surface layer.

[0084] Figure 12 is a schematic diagram of a cross section along the width direction of a road in the pavement repair area after the surface course has been laid. Figure 12 shows a case where the current surface data for the surface course is at a higher elevation than the design surface data for the surface course. In other words, this means that the workers laid the surface course based on the design surface data for the surface course, but the elevation ended up being higher than the design surface data.

[0085] The difference in elevation between the current surface elevation and the reference elevation is +c1 (mm) for L2, +c2 (mm) for L1, +c3 (mm) for CL, +c4 (mm) for R1, and +c5 (mm) for R2. Note that c1 to c5 are positive numbers.

[0086] In step S19, the control unit 5C of the terminal device 5 adds up the elevation differences calculated in steps S12 and S18 to calculate the elevation difference between the pavement thickness of the actually laid surface course and the design thickness of the surface course. As shown in Fig. 13, the elevation difference from the design thickness of the base course is b1 + c1 (mm) for L2, b2 + c2 (mm) for L1, b3 + c3 (mm) for CL, b4 + c4 (mm) for R1, and b5 + c5 (mm) for R2.

[0087] In step S20, the control unit 5C of the terminal device 5 calculates the pavement thickness of the actually laid surface layer by adding the elevation difference calculated in step S19 to the designed thickness of the surface layer. As shown in Fig. 13, the pavement thickness of the surface layer is b1 + c1 + T2 (mm) for L2, b2 + c2 + T2 (mm) for L1, b3 + c3 + T2 (mm) for CL, b4 + c4 + T2 (mm) for R1, and b5 + c5 + T2 (mm) for R2.

[0088] In step S21, the control unit 5C of the terminal device 5 creates an as-built management table of the thickness of the surface layer that has actually been laid, as shown in FIG.

[0089] As described above, as shown in Figure 14(a), the current position of a specified point on the cutting layer surface (for example, a point on CL) is measured using the total station 2, and after laying the base layer above the cutting layer, the pavement thickness of the base layer can be calculated by using the total station 2 to measure the current position of a point on the base layer surface directly above the specified point on the cutting layer surface, as shown in Figure 14(b).

[0090] For example, if the pavement thickness of the base layer (a3 + b3 + T1 (mm)) is greater than the design thickness (T1), then the design thickness of the base layer is met. On the other hand, if the pavement thickness of the CL (a3 + b3 + T1 (mm)) is less than the design thickness (T1), then the design thickness of the base layer is not met. The same applies to the pavement thicknesses of L2, L1, R1, and R2. In a similar manner, the pavement thickness of the base layer can be managed at any location within the road pavement repair area.

[0091] Similarly, after laying the surface layer above the base layer, the pavement thickness of the surface layer can be calculated by measuring the current position of a point on the surface of the surface layer directly above a specified point on the cutting layer surface using a total station 2, as shown in Figure 14(c).

[0092] For example, if the pavement thickness of the surface course (CL), b3 + c3 + T2 (mm), is greater than the design thickness (T2), then the design thickness of the base course is ensured. On the other hand, if the pavement thickness of CL, b3 + c3 + T2 (mm), is less than the design thickness (T2), then the design thickness of the surface course is not ensured. The same applies to the pavement thicknesses of L2, L1, R1, and R2. In the same way, the pavement thickness of the surface course can be managed at any location within the pavement repair area of ​​the road.

[0093] In this way, by using the as-built management program of this embodiment, as shown in Figure 15, when the design surface data of the cutting layer, the current position data of each point on the cutting layer surface, the design surface data of the base layer, the current position data of each point on the base layer surface, the design surface data of the surface layer, and the current position data of each point on the surface layer surface are input into the terminal device 5, an as-built management table for the base layer thickness and an as-built management table for the surface layer thickness are created.

[0094] (width management) In the as-built management system 1, as-built management of the surface layer width and the base layer width will be described with reference to Figs.

[0095] Controlling the surface layer width and base layer width means controlling whether the surface layer and base layer are laid properly with the proper width in accordance with the design surface data and design thickness.

[0096] The thickness of the surface layer and base layer is managed as finished as described above, and during this process, the distance between both ends of the road width is calculated based on the three-dimensional coordinates of each point measured by the total station 2, and this distance is managed as the pavement repair width.

[0097] Specifically, as shown in Fig. 16, for example, when the surface of the cutting layer is exposed, the width of the cutting layer is calculated based on the current positions of the left and right ends of the cutting layer surface measured by the total station 2. Then, when the surface of the base layer and the surface of the surface layer are exposed, the width of the base layer and the width of the surface layer are similarly calculated based on the current positions of the left and right ends of the base layer surface and the surface layer surface measured by the total station 2. This makes it possible to manage the width of each layer, as shown in Fig. 17.

[0098] (extended management) In the as-built management system 1, as-built management of the extension of the surface layer and the extension of the base layer will be described with reference to Figs.

[0099] Controlling the extension (length) of the surface layer and the extension of the base layer means controlling whether the surface layer and base layer are laid properly to the proper extension in accordance with the design surface data and design thickness.

[0100] Specifically, as shown in Figure 18, when a base layer is laid above a cutting layer, if the base layer is properly laid at the start and end points of the cutting layer, it is considered that the base layer is properly laid over the entire extension direction of the paving plan area. The same applies when a surface layer is laid above the base layer.

[0101] The design surface data for each layer contains design information called "route," which, as shown in Figure 19, contains a "linearity" that extends along the road's extension direction at the center of the road's width, and "start and end points" that specify the length of the "linearity." Figure 19(a) shows the case of a straight road, and Figure 19(b) shows the case of a curved road. Therefore, by checking whether each layer is properly laid at the start and end points of the paving plan area, it is possible to confirm whether each layer is properly laid over the entire extension direction of the paving plan area.

[0102] For example, let us consider a case where a surface course has been laid above a base course and the worker checks whether the surface course has been properly laid at the end of the paving plan area. After the surface course has been laid, the worker displays the road around the end of the paving plan area on the display screen 5a of the terminal device 5, as shown in Figure 20(a). At this time, a mark indicating the end of the paving plan area and the end of the paving plan area (a line along the width direction of the paving plan area) are displayed on the road around the end of the paving plan area displayed on the display screen 5a.

[0103] After that, with the surface course laid, the worker installs a prism 3 at a point on the surface of the surface course and measures the current position of that point using the total station 2. The measured current position data is then supplied from the total station 2 to the terminal device 5, and the measured position is displayed as a circle (◯) on the display screen 5a, as shown in Figure 20(b). Therefore, the worker checks the measurement position on the display screen 5a and measures the current position of the surface of the surface course near the end point of the paving plan area using the total station 2 while changing the installation location of the prism 3. Note that Figure 20(b) shows the case where the current position of the end point of the paving plan area is measured using the total station 2.

[0104] When the current position near the end point of the paving plan area is measured by the total station 2, the current position is displayed on the display screen 5a of the terminal device 5. Therefore, the worker can check whether the surface course has been properly laid at the end point of the paving plan area by using the altitude (height) included in the three-dimensional coordinates indicating the current position near the end point of the paving plan area. In this embodiment, the altitude (height) included in the three-dimensional coordinates indicating the current position near the end point of the paving plan area is displayed on the display screen 5a of the terminal device 5 as information indicating that the surface course has been properly laid at the end point.

[0105] In this embodiment, if the measurement position of the surface course surface measured by the total station 2 is the same as or close to the end point position included in the design surface data of the surface course, it is possible to confirm whether the surface course has been properly laid at the end point of the paving plan area. On the other hand, if the measurement position of the surface course surface is too far from the end point of the paving plan area, it is difficult to confirm that the surface course has been properly laid at the end point of the paving plan area.

[0106] Therefore, in this embodiment, when the measurement position of the surface layer measured by the total station 2, such as measurement position A1 shown in Figure 21, is within a specified value (for example, ±50 mm) from the end point, it is possible to confirm that the surface layer has been properly laid at the end point of the paving plan area.

[0107] On the other hand, if the measurement position of the surface of the surface measured by the total station 2, as in measurement position A2 shown in Figure 21, is farther away from the end point than a specified value (for example, ±50 mm), it is necessary to move the installation location of the prism 3 closer to the end point of the paving plan area and redo the measurement using the total station 2.

[0108] In the same manner as described above, when a surface course is laid above a base course, it is possible to check whether the surface course has been properly laid at the start point of the paving plan area. Also, when a base course is laid above a cutting course, it is possible to check whether the surface course has been properly laid at the start and end points of the paving plan area.

[0109] Furthermore, when managing the extension of the surface layer and the extension of the base layer, it is also possible to use the design surface data of each layer.

[0110] First, prepare the design surface data for each layer and the road design alignment (route) information. The design surface data is surface data (3D TIN model) that includes the coordinates of any point within the area enclosed by the dotted line in Figure 22. There are multiple linear change points between the start and end points of the road design alignment, and the alignment is formed by connecting the coordinates of these multiple change points with straight lines or curves. The total length of the alignment is the design length.

[0111] Consider a case where the current positions of the start and end points of a pavement repair area are measured near the start and end points of the pavement planning area. As shown in Figure 23, which is a plan view of the pavement planning area, if the current position of the measured start point is outside the range of the design surface data (the range surrounded by the dotted line in Figure 23), it is considered that the length of the pavement repair area has increased. Similarly, if the current position of the measured end point is outside the range of the design surface data (the range surrounded by the dotted line in Figure 23), it is considered that the length of the pavement repair area has increased.

[0112] For example, if the length of the pavement repair area increases by n1 near the start point and by n2 near the end point, Length of finished product = Design length + n1 + n2 is.

[0113] The design surface data has x-, y-, and z-coordinates for any point within the paving planning area, but the x- and y-coordinates of the measured current position in the plan view of the paving planning area can be used to determine whether or not a point is within the paving planning area.

[0114] In contrast, as shown in Figure 24, a plan view of the pavement planning area, if the current position of the measured starting point is inside the range of the design surface data (the range surrounded by the dotted line in Figure 24), it is considered that the length of the pavement repair area has decreased. Similarly, if the current position of the measured ending point is inside the range of the design surface data (the range surrounded by the dotted line in Figure 24), it is considered that the length of the pavement repair area has decreased.

[0115] For example, if the length of the pavement repair area decreases by n3 near the start point and by n4 near the end point, As-built extension = Design extension - n3 - n4 is.

[0116] Furthermore, if it is dangerous to enter the road when measuring the current positions of the start and end points of the pavement repair area, it is also possible to measure the current positions of both ends of the width (L, R) of the starting point, and use the midpoint of the line connecting those points as the center point in the width direction of the road (starting point of the alignment), as shown in Figure 25. Similarly, it is also possible to measure the current positions of both ends of the width (L, R) of the end point, and use the midpoint of the line connecting those points as the center point in the width direction of the road (end point of the alignment). Therefore, even if it is dangerous to enter the road, it is possible to calculate the excess or deficiency in length.

[0117] As mentioned above, for example, if the current position of the measured starting point is outside the range of the design surface data, it is considered that the length of the pavement repair area has increased. However, as shown in Figure 26, if the current position of the starting point is outside the range of the design surface data, the current position of the starting point has not been measured properly, so it is considered a measurement error.

[0118] Therefore, if the current position of the measured starting point is outside the extension direction of the range of the design surface data, it is considered that the extension of the pavement repair area has increased, but if the current position of the starting point is outside the lateral direction of the range of the design surface data, it is considered a measurement error because the current position of the starting point has not been measured properly.

[0119] In other words, if the current position of the measured starting point is outside the range of the design surface data, and the straight line connecting the design starting point and the measured point falls within the range of the design surface data, this is considered a measurement error because the road was bent to measure the length.

[0120] The linear information of the road design used to manage the extension of the surface course and the extension of the base course may be data of linear information newly created for the purpose of managing the completed form, or data of existing linear information.

[0121] In this embodiment, when pavement repair work is performed by laying a base layer above a cutting layer, the cutting layer is the "first layer" of the present invention, and the base layer is the "second layer" of the present invention. When pavement repair work is performed by laying a surface layer above the base layer, the base layer is the "first layer" of the present invention, and the surface layer is the "second layer" of the present invention.

[0122] As described above, the as-built condition management method of this embodiment is a method for managing the as-built condition of the thickness of a second layer when pavement repair work is performed to lay a second layer above a first layer, and includes a design data acquisition step of acquiring design surface data of the first layer, a design thickness of the second layer, and design surface data of the second layer; a first measurement step of measuring the current position of each point on the surface of the first layer using a total station 2 when the surface of the first layer is exposed; and a first calculation step of calculating a first elevation difference between the current elevation and the reference elevation for each point on the surface of the first layer based on the design surface data of the first layer acquired in the design data acquisition step and the current positions of each point on the surface of the first layer measured in the first measurement step. The method includes a second measurement step of measuring the current position of each point on the surface of the second layer using a total station 2 when the second layer is laid above the first layer; a second calculation step of calculating a second elevation difference between the current elevation and the reference elevation for each point on the surface of the second layer based on the design surface data of the second layer acquired in the design data acquisition step and the current positions of each point on the surface of the second layer measured in the second measurement step; and a pavement thickness calculation step of calculating the pavement thickness of the second layer for each point on the surface of the second layer based on the first elevation difference calculated in the first calculation step, the second elevation difference calculated in the second calculation step, and the design thickness of the second layer acquired in the design data acquisition step.

[0123] The as-built management device (terminal device 5) of this embodiment is a terminal device 5 that manages the as-built shape of the thickness of a second layer when pavement repair work is performed to lay a second layer above a first layer, and includes a design data storage unit 18 (design data storage means) that stores design surface data of the first layer, a design thickness of the second layer, and the design surface data of the second layer, a position data storage unit 19 (first position data storage means) that stores the current positions of each point on the surface of the first layer measured by the total station 2 when the surface of the first layer is exposed, and a first calculation unit 12 (first calculation means) that calculates a first elevation difference between the current elevation and the reference elevation for each point on the surface of the first layer based on the design surface data of the first layer stored in the design data storage unit 18 and the current positions stored in the position data storage unit 19. The system is equipped with a position data memory unit 19 (second position data memory means) that stores the current position of each point on the surface of the second layer measured by the total station 2 when the second layer is laid above the first layer, a second calculation unit 14 (second calculation means) that calculates a second elevation difference between the current elevation and the reference elevation for each point on the surface of the second layer based on the design surface data of the second layer stored in the design data memory unit 18 and the current position stored in the position data memory unit 19, and a pavement thickness calculation unit 15 (pavement thickness calculation means) that calculates the pavement thickness of the second layer for each point on the surface of the second layer based on the first elevation difference calculated by the first calculation unit 12, the second elevation difference calculated by the second calculation unit 14, and the design thickness of the second layer stored in the design data memory unit 18.

[0124] The as-built management program of this embodiment is a program for managing the as-built shape of the thickness of a second layer when pavement repair work is carried out to lay a second layer above a first layer, and includes a computer including a design data receiving unit 10 (design data receiving means) that receives design surface data of the first layer, a design thickness of the second layer, and the design surface data of the second layer, a first position data receiving unit 11 (first position data receiving means) that receives current position data of each point on the surface of the first layer measured by a total station 2 when the surface of the first layer is exposed, and a first calculation unit 12 (first calculation means) that calculates a first elevation difference between the current elevation and the reference elevation for each point on the surface of the first layer based on the design surface data of the first layer received by the design surface data receiving unit 10 and the current position data of each point on the surface of the first layer received by the first position data receiving unit 11. a second position data receiving unit 13 (second position data receiving means) that receives current position data of each point on the surface of the second layer measured by the total station 2 when the second layer is laid above the first layer; a second calculation unit 14 (second calculation means) that calculates a second elevation difference between the current elevation and the reference elevation for each point on the surface of the second layer based on the design surface data of the second layer received by the design surface data receiving unit 10 and the current position data of each point on the surface of the second layer received by the second position data receiving unit 13; and a pavement thickness calculation unit 15 (pavement thickness calculation means) that calculates the pavement thickness of the second layer for each point on the surface of the second layer based on the first elevation difference calculated by the first calculation unit 12, the second elevation difference calculated by the second calculation unit 14, and the design thickness of the second layer received by the design surface data receiving unit 10.

[0125] As a result, the as-built management method, as-built management device, and as-built management program of this embodiment can properly manage the as-built thickness of the second layer when pavement repair work is carried out to lay a second layer above the first layer.

[0126] The as-built management method of this embodiment includes a first pavement width calculation step that calculates the widthwise distance between the current position of one end and the current position of the other end in the width direction of the pavement repair area based on the current positions of each point on the surface of the first layer measured in the first measurement step, and a second pavement width calculation step that calculates the widthwise distance between the current position of one end and the current position of the other end in the width direction of the pavement repair area based on the current positions of each point on the surface of the second layer measured in the second measurement step.

[0127] The finished product management device (terminal device 5) of this embodiment is equipped with a pavement width calculation unit 17 (first pavement width calculation means) that calculates the widthwise distance between the current position of one end and the current position of the other end in the width direction of the pavement repair area based on the current positions of each point on the first layer surface stored in the first position data storage means, and a pavement width calculation unit 17 (second pavement width calculation means) that calculates the widthwise distance between the current position of one end and the current position of the other end in the width direction of the pavement repair area based on the current positions of each point on the second layer surface stored in the second position data storage means.

[0128] In the as-built management program of this embodiment, the computer further functions as a pavement width calculation unit 17 (first pavement width calculation means) that calculates the widthwise distance between the current position of one end and the current position of the other end in the width direction of the pavement repair area based on the current position data of each point on the first layer surface received by the first position data receiving means, and a pavement width calculation unit 17 (second pavement width calculation means) that calculates the widthwise distance between the current position of one end and the current position of the other end in the width direction of the pavement repair area based on the current position data of each point on the second layer surface received by the second position data receiving means.

[0129] As a result, the as-built management method, as-built management device, and as-built management program of this embodiment can properly manage the as-built width of the second layer when pavement repair work is carried out to lay a second layer above the first layer.

[0130] The finished product management method of this embodiment includes a display step of displaying the positions of the start and end points of the paving planning area included in the second layer of design surface data on a display screen, and a third measurement step of measuring the current positions of the start and end points using a total station 2.

[0131] The finished product management device (terminal device 5) of this embodiment is equipped with a display control unit 30 (display control means) that displays on a display screen the positions of the start and end points of the paving planning area included in the design surface data of the second layer, a position data memory unit 19 (third position data memory means) that stores the current positions of the start and end points measured by the total station 2, and a display control unit 30 (information display means) that displays information indicating that the second layer is being laid at the start and end points based on the current positions of the start and end points stored in the position data memory unit 19.

[0132] In the finished product management program of this embodiment, the computer further functions as a display control unit 30 (display control means) that displays on a display screen the positions of the start and end points of the paving plan area included in the design surface data of the second layer, a second position data receiving unit 13 (third position data receiving means) that receives current position data of the start and end points measured by the total station 2 when the second layer is laid above the first layer, and a display control unit 30 (information display means) that displays information indicating that the second layer is being laid at the start and end points based on the current position data of the start and end points received by the second position data receiving unit 13.

[0133] As a result, the as-built management method, as-built management device, and as-built management program of this embodiment can properly manage the as-built extension (length) of the second layer when pavement repair work is carried out to lay a second layer above the first layer.

[0134] The above describes an embodiment of the present invention, but the specific configuration of each part is not limited to the above-described embodiment, and various modifications are possible within the scope of the spirit of the present invention.

[0135] In the above embodiment, the pavement thickness is managed at five locations (L2, L1, CL, R1, and R2) along the width of the road, at predetermined intervals (e.g., every 40 m) along the extension of the road's pavement repair area. However, this is not limited to this. For example, the pavement thickness may be managed at any location along the extension of the road's pavement repair area. Furthermore, the pavement thickness may be managed at locations other than the five locations (L2, L1, CL, R1, and R2) along the width of the road.

[0136] In the above embodiment, in order to manage the as-built condition of the pavement thickness of each layer, the total station 2 measures the current position of each point at the start end (including the start point) and end end (including the end point) of the road pavement repair area to manage the as-built condition of the pavement thickness, and the current positions of each point measured at this time are used to manage the as-built condition of the extension (length) of the road pavement planning area. However, this is not limited to this. For example, if the current positions of each point are not measured at the start end (including the start point) and end end (including the end point) of the road pavement repair area to manage the as-built condition of the extension (length) of the road pavement planning area, the total station 2 may separately measure the current positions at the start end and end end of the road pavement repair area to manage the as-built condition of the extension (length) of the road pavement planning area.

[0137] In the above embodiment, the pavement repair work is described as a case in which two layers, a base layer and a surface layer, are laid above a cutting layer that serves as a reference surface in the pavement repair area. However, this is not limited to this. For example, only one surface layer may be laid above the reference surface. Alternatively, three or more layers, including the surface layer, may be laid above the reference surface.

[0138] In the above embodiment, an example of a procedure for performing as-built management of the surface layer thickness and the base layer thickness in the as-built management system 1 has been described, but the present invention is not limited to this. For example, in step S2 of Fig. 6, design surface data for the cutting layer and the base layer is created by a personal computer based on the design surface data for the surface layer, and in step S3 of Fig. 6, this is input to the terminal device 5, but the design surface data for the cutting layer and the design surface data for the base layer may be input to the terminal device 5 in a different procedure.

[0139] In the above embodiment, an example of the pavement thickness as-built management table is shown, but the present invention is not limited to this. For example, the contents recorded in the pavement thickness as-built management table may be different. [Explanation of symbols]
