Description

Technical Field

[0001] This application discloses a planning support system for assisting in the planning of excavation of land for building construction, a planning support device used in such a planning support system, and a planning support program for realizing such a planning support device.

Background Art

[0002] When constructing a building such as a house, when performing foundation work, it is necessary to plan excavation such as setting the excavation range and calculating the amount of surplus soil. Conventionally, the excavation plan has been carried out by so-called manual work such as manual measurement and judgment based on experience. The formulation of an excavation plan by manual work has caused various problems such as not only human errors, but also errors in calculating the amount of surplus soil, errors due to individual capabilities, and variations in required time. Therefore, the applicants of this application have proposed a design GL integration system capable of obtaining the amount of disposed soil and the amount of imported soil (Patent Document 1).

Embodiments for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present invention will be described in detail. Note that the following embodiments are an example of embodying the present invention and do not have the character of limiting the technical scope of the present invention.

[0019] <Application Example> The plan support system disclosed in the present application is used to support the formulation of excavation plans for land for constructing buildings such as houses. Further, the plan support system disclosed in the present application is applied in cooperation with systems such as a geographic information system (GIS: Geographic Information System) and a design support system (CAD: Computer Aided Design). Hereinafter, a plan support system using the plan support device 1 shown in the drawings will be described while referring to the drawings.

[0020] <System Configuration> Figure 1 is a conceptual diagram illustrating an example of a planning support system using the planning support device 1 disclosed in this application. The planning support system includes a planning support device 1 that performs the main processing within the system. The planning support device 1 is connected to a communication network such as a LAN (Local Area Network), WAN (Wide Area Network), dedicated communication network, or the Internet. A terminal device 2 used by the person in charge of planning land excavation is connected to the communication network NW. Furthermore, various devices such as a geographic information device 3 using a server computer that provides GIS, a building information device 4 that stores building information about the building to be constructed, and a drawing information device 5 using a server computer that provides a CAD system are connected to the communication network NW and can be accessed from the planning support device 1.

[0021] The planning support device 1 receives access from the terminal device 2 operated by the person in charge and executes various processes related to the planning support method disclosed in this application. The geographic information device 3 is a database server that is part of a geographic information system and is linked to an external or internal geographic information system. The geographic information device 3 stores geographic information such as topography, land use areas, and road networks, associated with location information indicating latitude and longitude or address. The building information device 4 is a database server that stores various building information such as the owner, installation location, structure, construction method, materials used, and various information related to materials, associated with a building ID that identifies the building. The drawing information device 5 is a database server that is linked to or is part of a design support system. The drawing information device 5 stores structural information indicating the building's foundation structure, including CAD information showing building drawings, associated with a building ID that identifies the building.

[0022] For the sake of explanation, the planning support device 1, geographic information device 3, building information device 4, and drawing information device 5 are each represented as a single device using a computer such as a server computer, but they may also be a collection of multiple devices and may be linked with external devices. Furthermore, while the planning support device 1 is shown being operated via a terminal device 2 operated by a person in charge, it is also possible to configure the planning support device 1 to be operated directly by the person in charge.

[0023] <Device Hardware Configuration> Next, an example of the configuration of the planning support device 1 disclosed in this application will be described. Figure 2 is a block diagram schematically showing an example of the configuration of the planning support device 1 disclosed in this application. The planning support device 1 is a device that uses a computer such as a server computer. The planning support device 1 is equipped with various components such as a control unit 10, a storage unit 11, and a communication unit 12.

[0024] The control unit 10 is a processor such as a CPU (Central Processing Unit) that includes various circuits such as information processing circuits, timing circuits, and register circuits, and performs processing to control the entire device.

[0025] The storage unit 11 is a storage unit composed of non-volatile memory such as hard disks, SSDs (Solid State Drives), RAID (Redundant Arrays of Inexpensive Disks), and flash memory, and volatile memory such as various types of RAM (Random Access Memory). The storage unit 11 stores various programs, such as a basic program (OS: Operating System) and application programs that run on the basic program. As application programs, various programs such as the planning support program 110 for realizing the planning support device 1 disclosed in this application are stored.

[0026] The communication unit 12 is a communication device such as a LAN adapter, and can connect to a communication network NW to access various devices.

[0027] A computer with the various configurations exemplified above operates as a planning support device 1 by reading various programs, such as the planning support program 110, stored in the memory unit 11 under the control of the control unit 10, and executing various steps included in the read programs.

[0028] Terminal device 2 is a computer-based device, such as a client computer, operated by a designated person. Terminal device 2 comprises various components, including a control unit 20, a storage unit 21, an input unit 22, a display unit 23, an output unit 24, and a communication unit. The input unit 22 is a device used for operation input, such as a keyboard or mouse. The display unit 23 is a display device, such as a liquid crystal display. The output unit 24 is an output device, such as a printer.

[0029] <Software processing for the device> Next, the processing of various devices used in the planning support system disclosed in this application will be explained. Figure 3 is a flowchart showing an example of the planning support processing of the planning support device 1 disclosed in this application. The planning support processing is the process of assisting in the planning of excavation of land on which a building will be constructed. The person in charge operates the terminal device 2 to specify the building to be planned and inputs an instruction to start the planning support processing from the input unit 22. Based on the input instruction, the terminal device 2 transmits a planning support start command to the planning support device 1 via the communication network NW from the communication unit 25 to start the planning support processing. Upon receiving the planning support start command, the planning support device 1 executes the planning support processing by executing the planning support program 110 stored in the storage unit 11 under the control of the control unit 10.

[0030] The control unit 10 of the planning support device 1 identifies the target building based on the received planning support start command (S101), acquires building information related to the identified building (S102), acquires land information based on the building's construction site (S103), and acquires structural information (S104). The planning support device 1 identifies the building using the building ID included in the planning support start command. In steps S102 to S104, the planning support device 1 acquires building information, land information, and structural information from the building information device 4, geographic information device 3, and drawing information device 5, respectively, based on the building ID. The land information acquired in step S103 includes geographic information such as information indicating the state of the land before the building is constructed, topography, land use area, and road network. The structural information acquired in step S104 includes CAD information. In addition, some of the building information included in step S102 is also treated as structural information indicating the building's foundation structure.

[0031] Based on the acquired land information and structural information, the control unit 10 derives the construction GL, which serves as the vertical reference for the building to be constructed as indicated by the structural information, within the land indicated by the land information (S105), and derives the position of the building's foundation structure on the construction GL plane (S106). In steps S105 to S106, the control unit 10 derives a three-dimensional position as the position of the foundation structure, that is, a position that can be projected onto a three-dimensional coordinate system, i.e., a three-dimensional position including a horizontal coordinate indicating the position in the horizontal coordinate system and a vertical coordinate indicating the position in the vertical direction.

[0032] The control unit 10 derives the excavation shape from the building structure, floor plan, and other information included in the acquired structural information (S107). In step S107, based on the building structure and floor plan, the control unit distinguishes areas such as the area around the foundation and the floor slab, and derives the appropriate excavation depth and excavation shape for each.

[0033] The control unit 10 derives the pre-construction GL, which serves as the vertical reference for the current land, based on the land information (S108). The pre-construction GL in step 108 is the average value of the GL predicted before the start of building construction, and is derived based on factors such as the current GL, whether or not demolition work is carried out, whether or not preliminary excavation is performed, and whether or not ground improvement is performed.

[0034] Then, the control unit 10 derives the area to be excavated within the land based on the land information and structural information, the excavation shape, and the position of the reference structure, the ground level before construction, and the construction ground level (S109). In step S109, the excavation area is derived taking into account the horizontal position, vertical position, and shape to be excavated within the land.

[0035] Furthermore, the control unit 10 derives the amount of excavated soil to be generated or the amount of topsoil required based on information such as the excavation area, land information, and the difference in elevation between the pre-construction ground level (GL) and the construction GL (S110). In step S110, the land information includes information such as whether or not demolition is required for building construction, whether or not preliminary excavation is performed, whether or not ground improvement is performed, the type of building, and the specifications of the area around the foundation and the floor slab related to the building. In step S110, the amount of soil generated by the excavation work and the amount of soil required are calculated from various pieces of information, and the amount of excavated soil or topsoil is calculated by taking the difference.

[0036] Then, based on the land information and the location of the foundation structure, the control unit 10 derives the temporary storage area and the amount of soil to be temporarily stored generated by excavation (S111), and derives a transportation plan based on the temporary storage area and the amount of soil to be temporarily stored (S112). In step S110, the difference between the amount of soil generated and the amount of soil needed is simply taken, but there is not always enough space to temporarily store the generated soil. Therefore, in step S111, the temporary storage area and the amount of soil to be temporarily stored are derived, and in step S112, a transportation plan is derived to transport the soil as needed. For example, when constructing a building on a small plot of land where there is not enough space for temporary storage soil, even if the amount of soil generated by excavation and the amount of soil needed are equal, it becomes necessary to transport the soil generated along the way.

[0037] The control unit 10 outputs (transmits) various information obtained through derivation, such as the excavation shape, excavation range, amount of excavated soil or topsoil, temporary storage area and amount of temporary storage, and transportation plan, as planning support information from the communication unit 12 to the terminal device 2 via the communication network NW (S113).

[0038] Terminal device 2 receives planning support information, displays the received planning support information on display unit 23, and outputs it from output unit 24. The person in charge checks the planning support information and formulates a plan for excavating the land where the building will be constructed.

[0039] As described above, the planning support device 1 executes the planning support process.

[0040] Next, we will further explain the process of deriving the excavation area, which is performed in step S109 of the planning support process. Figure 4 is a flowchart showing an example of the first excavation area deriving process of the planning support device 1 disclosed in this application. The planning support device 1 performs excavation area deriving processes according to the foundation structure, such as a first excavation area deriving process for deriving the excavation area around the foundation, and a second excavation area deriving process for deriving the excavation area for the floor. The first excavation area deriving process illustrated in Figure 4 is a process for deriving the excavation area around the foundation. The planning support device 1 performs the first excavation area deriving process by executing the planning support program 110 under the control of the control unit 10.

[0041] The control unit 10 of the planning support device 1 sets the excavation range for the area surrounding the foundation that is subject to the first excavation range calculation process, based on the derived position of the foundation structure (S201). The excavation range set in step S201 is an area on the horizontal plane.

[0042] Figure 5 is a schematic floor plan showing an example of a building used in the first excavation range derivation process and the second excavation range derivation process of the planning support device 1 disclosed in this application. Figure 5 is a floor plan used, for example, in step S107 of the planning support process when deriving the shape of the excavation from information such as the building structure and floor plan included in the structural information. In step S201, the areas of the foundation periphery and the floor slab are distinguished from the floor plan illustrated in Figure 5. In the floor plan illustrated in Figure 5, the area shown by the shaded lines is the foundation periphery, and the other areas are other parts such as the floor slab.

[0043] Returning to the flowchart in Figure 4, the control unit 10 sets the excavation depth around the foundation based on the acquired land information, the derived location of the foundation structure, the shape of the excavation, etc. (S202), and compares the derived pre-construction GL with the construction GL (S203).

[0044] In step S203, if it is determined that the ground level before construction is lower than the construction ground level (S203:1), the control unit 10 derives a normal value for the excavation depth as the excavation depth (S204). The normal value for the excavation depth is, for example, 0.43m, which is set as the sum of a soil cover of 0.16m, a base thickness of 0.22m, and crushed stone of 0.05m.

[0045] In step S203, if it is determined that the ground level before construction is higher than the construction ground level (S203:2), the control unit 10 derives the excavation depth as the normal value of the excavation depth plus the difference between the ground level before construction and the construction ground level (S205).

[0046] Figures 6 and 7 are conceptual cross-sectional views illustrating an example of the first excavation range derivation process of the planning support device 1 disclosed in this application. Figure 6 conceptually shows a cross-section of the situation when it is determined in step S203 that the pre-construction GL is lower than the construction GL. As illustrated in Figure 6, when the pre-construction GL is lower than the construction GL, the normal value of the excavation depth, indicated by the double arrow, is derived as the excavation depth. Figure 7 conceptually shows a cross-section of the situation when it is determined in step S203 that the pre-construction GL is higher than the construction GL. As illustrated in Figure 7, when the pre-construction GL is higher than the construction GL, the value obtained by adding the difference between the pre-construction GL and the construction GL (GL difference) to the normal value of the excavation depth is derived as the excavation depth.

[0047] Returning to the flowchart in Figure 4, the control unit 10 derives the over-excavation rate (S206) based on the excavation shape derived in step S107. The over-excavation rate is an indicator for performing excavation while considering the excavation shape, such as the slope of the excavation surface.

[0048] Figure 8 is an explanatory diagram showing an example of the over-excavation rate in the first excavation range derivation process of the planning support device 1 disclosed in this application. Figure 8 shows the relationship between the foundation and the excavation range in the excavation process. The width of the lowest surface of the foundation is the base width, and the excavation range is the trapezoidal area in side view where the upper bottom surface is larger than the lower bottom surface. The width of the upper surface and the width of the bottom surface of the excavation range are defined as the excavation width (upper) and excavation width (lower), respectively. The distance from the bottom surface to the upper surface of the excavation range is the excavation depth. The over-excavation rate derived in step S206 is derived by the following formula.

[0049] Over-excavation rate = Over-excavation amount / Base width However, extra digging amount = (cutting width (bottom) + cutting width (top)) / 2 Also, the excavation width (bottom) = base width + excess excavation amount × 2 Cutting width (top) = Cutting width (bottom) + Cutting depth x TAN(RADIANS(30)) x 2

[0050] Returning to the flowchart in Figure 4, the control unit 10 derives the excavation range around the foundation based on the derived excavation depth and over-excavation rate, as well as the foundation height and horizontal projection area of ​​the foundation structure based on the structural information (S207).

[0051] As described above, the planning support device 1 performs the first excavation range extraction process.

[0052] Figure 9 is a flowchart illustrating an example of the second excavation range derivation process of the planning support device 1 disclosed in this application. The second excavation range derivation process illustrated in Figure 9 is a process for deriving the area to be excavated in the ground. The planning support device 1 executes the second excavation range derivation process by executing the planning support program 110 under the control of the control unit 10.

[0053] The control unit 10 of the planning support device 1 sets the excavation range of the floor slab that is subject to the second excavation range calculation process based on the derived floor slab position (S301). The excavation range set in step S301 is the range on the horizontal plane.

[0054] The control unit 10 sets the excavation depth for the ground floor based on acquired land information, derived ground floor location, excavation shape, etc. (S302), and compares the derived pre-construction ground level (GL) with the construction ground level (S303).

[0055] In step S303, if it is determined that the ground level before construction is lower than the construction ground level (S303:1), the control unit 10 determines that excavation is unnecessary (S304) and derives the amount of backfilling (S305).

[0056] In step S303, if it is determined that the ground level (GL) before construction is higher than the construction GL (S303:2), the control unit 10 sets the specifications for the concrete slab (floor concrete) from various information such as the building design and specifications included in the acquired building information (S306). In step S306, the control unit 10 performs a process to set one concrete slab that is suitable for the building specifications indicated in the building information from among moisture-proof concrete slab (60 mm thick), reinforcing concrete slab (80 mm thick), and concrete slab for preventing uplift (100 mm thick).

[0057] In step S306, if the setting is for a moisture-proof concrete slab (S306:1), the control unit 10 derives the excavation depth as the thickness of the moisture-proof concrete slab (60 mm) plus the difference between the pre-construction GL and the construction GL (S307).

[0058] In step S306, if the reinforced concrete slab is selected (S306:2), the control unit 10 derives the excavation depth as the thickness of the reinforced concrete slab (80 mm) plus the difference between the pre-construction ground level (GL) and the construction GL (S308).

[0059] In step S306, if a concrete slab for preventing uplift is set (S306:3), the control unit 10 derives the excavation depth as the thickness of the concrete slab for preventing uplift (100 mm) plus the difference between the ground level before construction and the construction ground level (S309).

[0060] Figures 10 and 11 are conceptual cross-sectional views illustrating an example of the second excavation range derivation process of the planning support device 1 disclosed in this application. Figure 10 conceptually shows a cross-section of the situation when it is determined in step 303 that the pre-construction ground level (GL) is lower than the construction ground level (GL). As illustrated in Figure 10, when the pre-construction ground level (GL) is lower than the construction ground level (GL), it is necessary to backfill the area without excavation in order to match the height of the concrete slab to the construction ground level. Figure 11 conceptually shows a cross-section of the situation when it is determined in step S303 that the pre-construction ground level (GL) is higher than the construction ground level (GL), and a 60 mm thick moisture-proof concrete slab is set. As illustrated in Figure 11, when the pre-construction ground level (GL) is higher than the construction ground level (GL), the excavation depth is derived by adding the difference between the pre-construction ground level (GL) and the construction ground level (GL) to the thickness of the set concrete slab.

[0061] Returning to the flowchart in Figure 9, the control unit 10 derives the excavation range for the ground floor based on the derived excavation depth and the horizontal projection area of ​​the foundation based on the structural information (S310).

[0062] As described above, the planning support device 1 performs the second excavation range extraction process.

[0063] The planning support device 1 derives the three-dimensional excavation range for all sections by executing either the first excavation range deriving process or the second excavation range deriving process for each section of the building to be constructed.

[0064] Next, we will explain the process of deriving the amount of excavated soil to be generated or the amount of topsoil required, which is performed in step S110 of the planning support process. Figure 12 is a flowchart of an example of the excavated soil amount, etc. deriving process of the planning support device 1 disclosed in this application. The planning support device 1 executes the excavated soil amount, etc. deriving process by executing the planning support program 110 under the control of the control unit 10.

[0065] The control unit 10 of the planning support device 1 derives the amount of excavated soil around the foundation using the following formula, which is the product of the excavation depth, over-excavation rate, foundation height, and horizontal projection area of ​​the foundation derived in the first excavation range derivation process (S401).

[0066] Excavation volume around the foundation = Excavation depth × Over-excavation rate × Foundation height × Horizontal projection area of ​​the foundation

[0067] The control unit 10 derives the amount of excavated soil for the floor slab using the following formula, which is the product of the floor slab excavation depth and the horizontal projection area of ​​the foundation derived in the second excavation range derivation process (S402). If the second excavation range derivation process determines that excavation is unnecessary, the derived backfill amount is derived as a negative amount of excavated soil.

[0068] Excavation volume for the floor = Excavation depth for the floor × Horizontal projection area of ​​the foundation

[0069] The control unit 10 derives the sum of the amount of excavated soil for the foundation structure and the amount of excavated soil for the floor slab as the amount of surplus soil (S403). If the amount of soil to be temporarily stored in the temporary storage area is derived, the amount of surplus soil will be the sum of the excavated soil amounts minus the amount of surplus soil. In that case, the amount of surplus soil is derived as the sum of the outer perimeter temporary storage amount, the inner perimeter temporary storage amount, and the arbitrary temporary storage amount. The outer perimeter temporary storage amount is the amount of soil that can be temporarily stored in the temporary storage area outside the foundation, the inner perimeter temporary storage amount is the amount of soil that can be temporarily stored in the temporary storage area inside the foundation, and the arbitrary temporary storage amount is the amount of soil that can be temporarily stored in a temporary storage area that can be set as appropriate. If the value in step S403 is negative, the obtained amount will be the required amount of topsoil.

[0070] As described above, the planning support device 1 performs the process of deriving the amount of excavated soil, etc.

[0071] As detailed above, the planning support system disclosed in this application has excellent effects, such as being able to support the planning of excavation by deriving information related to excavation, such as the location of the foundation structure and the excavation area, based on information such as land information and structural information.

[0072] The present invention is not limited to the embodiments described above and can be implemented in various other forms. Therefore, these embodiments are merely illustrative in all respects and should not be interpreted restrictively. The scope of the present invention is defined by the claims and is not restricted in any way by the text of the specification. Furthermore, any modifications or changes within the equivalent scope of the claims are all within the scope of the present invention.

[0073] For example, in the above embodiment, a configuration in which a planning support device 1, which is configured using a computer such as a server computer, is operated by a terminal device 2 is shown. However, the planning system disclosed in this application is not limited to this, and various system configurations are possible. For example, the planning support device 1 and the terminal device 2 may be integrated, and the person in charge may directly operate the planning support device 1. It is also possible to implement various system configurations, such as pre-storing necessary information from the geographic information device 3, building information device 4, and drawing information device 5 in the planning support device 1.
