These tasks require a large number of workers, and are handled manually, for example, through manual data entry into computer systems, paperwork, and on-site visual inspections. To achieve high accuracy, workers require advanced expertise and a high level of skill. Therefore, there is a need for significant automation and optimization of these tasks through the use of computer systems.

[0003] As an example of an information processing system for automating ground improvement work, Patent Document 1 discloses a construction management system that guides a pile driver to the pile core position based on position information obtained from a satellite positioning system such as GPS (Global Positioning System). In Patent Document 1, a construction management device mounted on the pile driver downloads a construction management program, setting parameters, and planning data appropriate to the construction site at the construction site, and then executes the construction management program using the setting parameters and planning data to manage the process of sequentially embedding multiple steel pipe piles at each pile core position. Furthermore, in Patent Document 1, the construction management device generates construction performance data each time it finishes embedding a steel pipe pile and sends it to a data server, and a personal computer (PC) in the management office creates a report based on the construction performance data obtained from the data server.

[0026] (Details of the functional configuration of the server device 200 according to the embodiment) [Support for the design review process of ground improvement] First, the support provided by server device 200 for the design review work of ground improvement will be explained below.

[0027] The data receiving unit 210 receives ground investigation data showing the results of the foundation's ground investigation and building design drawing data showing the building's design drawings from the user terminal 100, and stores them in the data storage unit 250. Here, the ground investigation data refers to data showing the results of investigations at five predetermined measurement points of the ground within the foundation area, as a result of conventionally known tests (hereinafter referred to as "SWS tests"), such as the Swedish sounding test and the screw weight penetration test. In this embodiment, the case in which a ground investigation is conducted at five measurement points is given as an example, but the number of measurement points for the ground investigation is not limited to this, and may be four or fewer measurement points, or six or more measurement points.

[0028] In the SWS test, a control device (not shown) is used to attach a screw point with a maximum outer diameter of 33.3 mm to the tip of a rod with an outer diameter of 19 mm. At each measurement point in the ground, the minimum load at which the rod sinks under a load of 1.00 kN or less is recorded as Wsw. In the SWS test, if the rod no longer sinks under a load of 1.00 kN, the rod is rotated, and the number of rotations required for a 0.25 m penetration (i.e., the number of half rotations) is measured as Na. In the SWS test, the number of half rotations Na is converted to a value per meter of penetration and recorded as Nsw.

[0029] Furthermore, for example, the ground investigation survey data is data that can be displayed in the table format shown in Figure 4, and for each item, such as "Survey Point Number" which indicates the identification number of the survey point, "Survey Date and Time" which indicates the date and time of the survey, and "Latitude and Longitude" which indicates the latitude and longitude of the survey point, along with their values, the data includes such items. For example, as shown in Figure 4, the ground investigation survey data includes data such as "Survey Point Number" is "1", "Survey Date and Time" is "Reiwa ○ Year △ Month □ Day 9:12~9:35", and "Latitude and Longitude" is "North Latitude: 3644.XXXA (36°44′A.BB″) East Longitude: 13702.YYYA (137°2′CC.DD″)".

[0030] Furthermore, the ground investigation survey data includes items and their values ​​for each "Survey Point Number" item, such as "Penetration Depth D (m)" indicating the depth of rod penetration D [m], "Load Wsw (kN)" indicating the minimum load Wsw [kN], "Half-Rotations Na (times)" indicating the number of half-rotations Na [times], "Half-Rotations Nsw (times) per meter" indicating the number of half-rotations Nsw [times] per meter, and "Soil Type" indicating the geology.As shown in Figure 4, the ground investigation survey data includes values ​​for "Penetration Depth D (m)", "Load Wsw (kN)", "Half-Rotations Na (times)", and "Half-Rotations Nsw (times) per meter" for every 25 cm of rod penetration. For example, in ground investigation data, if the "measurement point number" is "1" and the "penetration depth D (m)" is "0.25", the data includes "load Wsw (kN)" of "0.50", "half-rotation count Na (times)" of 0, indicating "self-settling", "half-rotation count Nsw (times) per 1m" of "0", and "soil type" indicating cohesive soil, such as "clayy".

[0031] The data extraction unit 220 extracts Wsw data, which shows the value of "load Wsw (kN)" for every 25 cm of rod penetration at all measurement points, and Nsw data, which shows the value of "half rotations Nsw (times) per meter", from the ground survey results data stored in the data storage unit 250. For example, the data extraction unit 220 extracts data showing the value of "load Wsw (kN)" ("0.50", "1.00", ..., "1.00") as Wsw data for measurement point number "1", and also extracts data showing the value of "half rotations Nsw (times) per meter" ("0", "0", ..., "92") as Nsw data for measurement point number "1". The data extraction unit 220 similarly extracts Wsw data and Nsw data for measurement points number "2", "3", "4", and "5".

[0032] The data format of the ground investigation results can be any format, such as document format, graphic format, or spreadsheet format. The data extraction unit 220 can, for example, extract Wsw data and Nsw data using a technique that recognizes characters within graphics, such as OCR (Optical Character Recognition), if the file in which the ground investigation results data is stored is a graphic format file such as a PDF (Portable Document Format) file.

[0033] Furthermore, the data extraction unit 220 extracts foundation area data, which indicates the area of ​​the foundation, from the building design drawing data stored in the data storage unit 250. Note that the building design drawing data may be data generated in any file format with an arbitrary extension that can be read, generated, and edited using various CAD (Computer-Aided Design) software. For example, the data extraction unit 220 extracts "72.5m" from building design drawing data (not shown). 2 If the data includes information that allows for the identification of the base area, such data is extracted as base area data.

[0034] The data generation unit 230 generates design review data including installation minimum number data and installation maximum interval data, which will be described later, based on various data such as the Wsw data, Nsw data, and base area data extracted by the data extraction unit 220, the reliability calculation formula data and installation minimum interval data to be described later, and stores the generated design review data in the data storage unit 250. Here, the installation minimum number data included in the generated design review data indicates the minimum installation number, which is the minimum value of the number of installations of the reinforcement, and the installation maximum interval data indicates the installation maximum interval, which is the maximum value of the installation interval between reinforcements, i.e., the so-called maximum pitch. In addition, the reliability calculation formula data used for generating the design review data indicates the reliability calculation formula for ground improvement based on a predetermined construction method, and the installation minimum interval data indicates the installation minimum interval, which is the minimum value of the installation interval between reinforcements, i.e., the so-called minimum pitch. In this embodiment, the minimum pitch is predetermined to be 0.5 m. The reliability calculation formula for ground improvement indicated by the reliability calculation formula data is, for example, the long-term allowable bearing capacity calculation formula for the reinforced ground in the conventionally known screw press method, and specifically, it is the mathematical formula shown by Equation (1) below.

[0035] (Equation (1)) q a =(1 - a s )·q sa + a s ·q pa

[0036] In the mathematical formula shown by Equation (1) above, q a is the value of the long-term allowable bearing capacity of the ground after reinforcement (kN / m 2 ), q sa is the value of the long-term allowable bearing capacity of the ground before reinforcement (original ground) (kN / m 2 ), and q pa is the value of the long-term allowable bearing capacity of the reinforcement (kN / m 2 ). In the above calculation formula, a s is the improvement rate of the ground by the reinforcement. Specifically, it is the value of the cross-sectional area A p of the reinforcement (m 2 ) divided by the value of the cross-sectional area A of the ground borne by the reinforcement (m 2The value obtained by dividing by (A p / A) is the case.

[0037] Here, the long-term allowable bearing capacity of the original ground is q. sa Value (kN / m 2 ) is a numerical value represented by, for example, the following number 2, where Ave(Wsw) is the average value of Wsw shown by the Wsw data, and Ave(Nsw) is the average value of Nsw shown by the Nsw data.

[0038] (Math 2) 30·Ave(Wsw) + 0.64·Ave(Nsw)

[0039] Therefore, the long-term allowable bearing capacity of the original ground is q sa Value (kN / m 2 This can be calculated based on the values ​​shown in the Wsw and Nsw data, for example, 23.14 kN / m 2 Furthermore, the long-term allowable bearing capacity q of the reinforcement is also a factor. pa Value (kN / m 2 ) is pre-set, for example, 230kN / m 2 That is the case.

[0040] Therefore, the long-term allowable bearing capacity q of the reinforced ground a Value (kN / m 2 If a sufficient value is set in advance based on the building, the improvement rate of the reinforcement a s This makes it possible to calculate the cross-sectional area A of the reinforcing body. p The value (m 2 ) is also set in advance; for example, if the outer diameter of the cylindrical reinforcing body is 430 mm, it is approximately 0.145 m 2 (3.14·(0.215) 2 ≈0.145[m 2 Therefore, the improvement rate a of the reinforcement is s If this is calculated, the value of the cross-sectional area A of the ground supported by the reinforcement body (m 2 ) can also be calculated. For example, q a =35.14[kN / m 2 ],q sa =23.14[kN / m 2 ],qpa =230[kN / m 2 ],A p =0.145[m 2 Let's consider the case where ]. In this case, the improvement rate a of the reinforcement is s , and regarding the cross-sectional area A of the ground supported by the reinforcement body, a s =0.058((35.14-23.14) / (230-23.14)≒0.058), A=2.5(0.145 / 0.058=2.5[m 2 The following is true:

[0041] Therefore, the long-term allowable bearing capacity q of the reinforced ground a The value is 35.14 kN / m 2 If that is sufficient, then one reinforcing bar will provide a cross-sectional area A of 2.5 m². 2 It can be seen that the ground can be reinforced. Also, the value of the cross-sectional area A of the ground supported by the reinforcement body (m 2 If the following is calculated, the value of the foundation area (m²) indicated by the foundation area data will be used. 2 The minimum number of reinforcing members that can be installed can be calculated from the following. For example, if the foundation area is 72.5m² 2 Therefore, the minimum number of reinforcing members to be installed is 29 (72.5 / 2.5 = 29 [members]). The maximum pitch between the reinforcing members is also calculated based on the value of the cross-sectional area A of the ground supported by the reinforcing members (m 2 ), the minimum number of units to be installed (units), the area of ​​the foundation (m²) 2 This can be determined from various values ​​such as the minimum pitch (0.5m). For example, the maximum pitch between reinforced bodies must be at least the minimum pitch (0.5m), and the cross-sectional area A of the ground supported by the reinforced bodies must be 2.5m 2 In such cases, the value predetermined as the standard value used by the user when setting the maximum pitch can be 2.0m.

[0042] The data generation unit 230 acquires the confidence calculation formula data and the minimum installation interval data stored in the data storage unit 250. The data generation unit 230 also acquires the above-mentioned calculation formula and predetermined values ​​q shown in the confidence calculation formula data. a ,q pa ,A pUsing the minimum pitch value (0.5m) indicated by the minimum installation interval data, the minimum number of reinforcing members to be installed (members) and the maximum pitch value (m) between reinforcing members are determined as described above, and minimum installation number data and maximum installation interval data indicating these values ​​are generated. The data generation unit 230 then generates design study data including the minimum installation number data and maximum installation interval data, and stores it in the data storage unit 250.

[0043] For example, the design study data is data that can be displayed in the table format shown in Figure 5, and for each measurement point, it includes items such as "Wsw" indicating Wsw data and "Nsw" indicating Nsw data, along with their values ​​(the penetration amount of the rod as described above, in 25cm increments). For example, as shown in Figure 5, the design study data includes data such as "No.1" indicating that the "measurement point number" is "1", and if the "investigation depth" indicating the "penetration depth D (m)" is "0.25", then "Wsw" is "0.50" and "Nsw" is "0".

[0044] Furthermore, for example, the design study data includes the "base area (m²)" which shows the cross-sectional area A of the ground. 2 The data includes items and their values ​​such as "base area", "maximum pitch (m)" which indicates the maximum spacing between installations, and "number of installations (pieces)" which indicates the minimum number of installations. For example, the design study data includes data such as "base area" is "72.5", "maximum pitch (m)" is "2.0", and "number of installations (pieces)" is "29".

[0045] The design study data includes, but is not limited to, the minimum number of installations data and the maximum installation interval data mentioned above. For example, the design study data may include minimum installation interval data indicating the minimum pitch. Also, for example, the design study data may include judgment result data indicating the result of the determination of the reliability of ground improvement based on the minimum number of installations data and the maximum installation interval data. Furthermore, for example, the design study data may also include various data such as foundation area data identified from the building design drawings, long side data indicating the length of the long side of the foundation, and short side data indicating the length of the short side of the foundation.

[0046] The data transmission unit 240 transmits the design study data generated by the data generation unit 230 to the user terminal 100.

[0047] [Support for creating layout diagrams of reinforcement structures] Next, the support provided by the server device 200 for creating the layout diagram of the reinforcement body will be explained below.

[0048] The data receiving unit 210 receives design study data, building design drawing data, and installation condition data indicating the installation conditions for reinforcing bodies used for ground improvement, which are generated based on predetermined construction methods, from the user terminal 100, and stores them in the data storage unit 250. Here, the installation condition data is data indicating the conditions that must be followed when installing reinforcing bodies, which are predetermined by the construction company on the premise that they conform to the above-mentioned construction method, although this will be described in detail later. Note that the data received by the data receiving unit 210 may have been changed from what is stored in the data storage unit 250 by input from the user using the user terminal 100. For this reason, if the data stored in the data storage unit 250 differs from the data received from the user terminal 100, it updates the data to the data received from the user terminal 100.

[0049] The data extraction unit 220 extracts the minimum number of installation data and the maximum installation interval data from the design study data stored in the data storage unit 250. The data extraction unit 220 also extracts foundation plan data showing the foundation plan from the building design drawing data stored in the data storage unit 250.

[0050] The foundation plan data is, for example, data capable of displaying the plan shown by the solid line in Figure 6. The data extraction unit 220 extracts the foundation plan data from the building design drawing data by generating data showing a plan that is a line drawing connecting the midpoint line between the straight line showing the outer surface of the exterior wall shown by the dashed line in Figure 6 and the straight line showing the inner surface shown by the dashed line in Figure 6, based on the building design drawing data. The foundation plan data may be generated in a data format with any extension that can be handled by various CAD software, for example, similar to the building design drawing data. Furthermore, the data extraction unit 220 may change these data formats using known software, such as a CAD converter, for the purpose of extracting the foundation plan data from the building design drawing data.

[0051] The data generation unit 230 generates reinforcement arrangement diagram data showing the arrangement of reinforcement bodies based on the installation condition data stored in the data storage unit 250, as well as the minimum number of reinforcement bodies to be installed, the maximum spacing between reinforcement bodies to be installed, and the foundation plan data extracted by the data extraction unit 220. The data generation unit 230 generates reinforcement arrangement diagram data showing the arrangement of reinforcement bodies on the plan shown in the foundation plan data, with a number of reinforcement bodies equal to or greater than the minimum number to be installed indicated by the minimum number of reinforcement bodies to be installed, satisfying the installation conditions indicated by the installation condition data, and with an installation interval equal to or less than the maximum pitch indicated by the maximum spacing between reinforcement bodies to be installed, and stores this data in the data storage unit 250.

[0052] Here, the installation condition data includes, for example, data indicating a first installation condition, such as that the central axis of the reinforcing body must be offset inward from the foundation line so that the outer surface of the circular cross-section reinforcing body is in contact with the outer surface of the building's outer wall, which has a linear cross-section, on the plan view. The installation condition data also includes, for example, data indicating a second installation condition, such as that reinforcing bodies must be placed at the corners of the foundation, such as 90° convex corners and 270° concave corners. The installation condition data also includes, for example, data indicating a third installation condition, such as that reinforcing bodies should be placed wherever possible if there is an intersection point between a straight line passing through the central axes of two or more reinforcing bodies placed at adjacent corners and a straight line of the foundation. The installation condition data also includes, for example, data indicating a fourth installation condition, such as that priority must be given to placing reinforcing bodies at equal intervals as much as possible, except at the aforementioned corners.

[0053] First, the data generation unit 230 places the reinforcing bodies on the plan view at intervals less than or equal to the maximum pitch, according to each installation condition indicated by the installation condition data, counts the number of reinforcing bodies placed on the plan view, and determines whether the counted number of installed bodies is equal to or greater than the minimum number of installed bodies. If the counted number of installed bodies is equal to or greater than the minimum number of installed bodies, the data generation unit 230 uses the plan view in which the reinforcing bodies are placed as the reinforcing body layout diagram, generates reinforcing body layout diagram data showing the layout diagram, and stores it in the data storage unit 250.

[0054] The reinforcement arrangement diagram data is, for example, data capable of displaying a plan view shown by the solid line in Figure 7. The data generation unit 230 arranges the reinforcement so that the outer surface of the circular reinforcement shown by the solid line in Figure 7 is in contact with the outer surface of the outer wall shown by the dashed line in Figure 7, according to the first installation conditions. For example, if the thickness of the outer wall is 150 mm and the distance between the straight line of the foundation and the straight line of the outer surface of the outer wall is 75 mm (150 / 2 = 75 [mm]), then if the radius of the reinforcement is 215 mm, the reinforcement is arranged so that the central axis of the reinforcement is 140 mm (215 - 75 = 140 [mm]) inward from the straight line of the foundation.

[0055] Furthermore, the data generation unit 230 places the reinforcing body indicated by "1" enclosed by a solid circle in Figure 7 at five convex corner portions and one concave corner portion of the foundation, for example, according to the second installation condition. Also, the data generation unit 230 places the reinforcing body indicated by "2" enclosed by a solid circle in Figure 7 at the middle portion of the straight line of the foundation, for example, according to the third installation condition. Also, the data generation unit 230 places the reinforcing body indicated by "3" enclosed by a solid circle in Figure 7 at as equal intervals as possible, with installation intervals of no more than the maximum pitch, at the middle portion of the straight line of the foundation, for example, according to the fourth installation condition. Subsequently, the data generation unit 230 places the reinforcing body indicated by "4" enclosed by a solid circle in Figure 7 at as equal intervals as possible, with installation intervals of no more than the maximum pitch, at the inner portion of the foundation, for example, according to the fourth installation condition.

[0056] The data generation unit 230 then counts the number of reinforcing bodies installed on the plan view and determines that there are 34 of them, and determines that the counted 34 bodies are equal to or greater than the minimum number of 29 bodies required for installation. As a result, the data generation unit 230 can generate reinforcing body layout diagram data showing the layout of the reinforcing bodies in a plan view with a total of 34 reinforcing bodies, and store this data in the data storage unit 250. The reinforcing body layout diagram data may be generated in a data format with any extension that can be handled by various CAD software, for example, similar to the building design drawing data and the foundation plan view data. Furthermore, the data generation unit 230 may change the data format of the foundation plan view data using a CAD converter, for example, in order to generate the reinforcing body layout diagram data from the foundation plan view data.

[0057] The data transmission unit 240 transmits the reinforcement arrangement diagram data generated by the data generation unit 230 to the user terminal 100.

[0058] [Support for construction cost estimation work] Next, the support provided by the server device 200 for construction cost estimation will be explained below.

[0059] The data receiving unit 210 receives reinforcement arrangement diagram data and construction cost data related to the cost of burying the reinforcement from the user terminal 100, and stores them in the data storage unit 250. Here, the construction cost data includes, for example, burial unit cost data showing the unit price per reinforcement as an example of the cost required to bury the reinforcement. If the data stored in the data storage unit 250 differs from the data received from the user terminal 100, it updates the data with the data received from the user terminal 100.

[0060] The data generation unit 230 generates estimate data showing an estimate for ground improvement work based on the reinforcement body layout diagram data and construction cost data stored in the data storage unit 250. For example, first, the data generation unit 230 counts the number of reinforcement bodies installed in the layout diagram shown in the reinforcement body layout diagram data, and identifies the unit price per reinforcement body from the buried unit price data included in the construction cost data. Then, the data generation unit 230 calculates an amount by multiplying the number of reinforcement bodies by the unit price, and generates estimate data including estimate amount data showing the estimated amount calculated.

[0061] The data transmission unit 240 transmits the quotation data generated by the data generation unit 230 to the user terminal 100.

[0062] [Regarding the management of the construction process and support for guiding construction equipment to the pile center position] Next, the server device 200's management of the construction process and its support for guiding the construction machine to the pile center position will be explained below.

[0063] The data receiving unit 210 receives reinforcement body layout diagram data and foundation position data indicating the predetermined latitude and longitude of the foundation from the user terminal 100, and stores them in the data storage unit 250. If the data stored in the data storage unit 250 differs from the data received from the user terminal 100, it updates the data stored in the data storage unit 250 with the data received from the user terminal 100.

[0064] The data generation unit 230 generates reinforcement position data that can identify the latitude and longitude of the central axis of all reinforcements placed in the layout diagram, based on the reinforcement layout diagram data and foundation position data stored in the data storage unit 250. The data generation unit 230 also generates guidance sequence data that indicates the guidance sequence, which is the order in which the construction machine is guided to bury the reinforcements, based on the generated reinforcement position data. Furthermore, the data generation unit 230 generates construction process management data that the user uses to manage the construction process at the construction site, based on the reinforcement position data and guidance sequence data. Here, the construction process management data includes various types of data, such as data showing manuals for all construction processes and data showing check items for each construction process.

[0065] The data transmission unit 240 transmits the reinforcement body position data, guidance sequence data, and construction process management data generated by the data generation unit 230 to the construction management terminal 300.

[0066] [Support for preparing construction reports] Next, the support provided by the server device 200 for the creation of construction reports will be explained below.

[0067] The data receiving unit 210 receives construction performance data from the construction management terminal 300, showing the actual installation of reinforcement bodies, and stores it in the data storage unit 250. The construction performance data includes, for example, data showing the time, latitude, and longitude of installation for each reinforcement body.

[0068] The data generation unit 230 generates construction report data, which represents a construction report, based on the construction performance data stored in the data storage unit 250.

[0069] The data transmission unit 240 transmits the construction report data generated by the data generation unit 230 to the user terminal 100.

[0070] (Details of the functional configuration of the user terminal 100 according to the embodiment) When a user is performing a design review for ground improvement, the data transmission unit 110 transmits pre-acquired ground investigation survey data and building design drawing data to the server device 200, and the data reception unit 120 receives the design review data from the server device 200. In this case, the data display unit 130 displays, for example, the design review data shown in Figure 5.

[0071] Furthermore, when a user creates a reinforcement layout diagram, the data transmission unit 110 transmits the previously acquired design study data, building design drawing data, and installation condition data to the server device 200, and the data reception unit 120 receives the reinforcement layout diagram data from the server device 200. In this case, the data display unit 130 displays, for example, the reinforcement layout diagram data shown by the solid line in Figure 7. Note that the installation condition data is, for example, generated and stored by the user themselves using the user terminal 100.

[0072] Furthermore, when a user performs construction cost estimation work, the data transmission unit 110 transmits the previously acquired reinforcement arrangement diagram data and construction cost data to the server device 200, the data reception unit 120 receives the estimate data from the server device 200, and the data display unit 130 displays the estimate data. Note that the construction cost data is, for example, generated and stored by the user themselves using the user terminal 100.

[0073] Furthermore, when the user performs tasks such as guiding the construction machine to the pile center position and creating a construction report, the data transmission unit 110 transmits the previously acquired reinforcement arrangement diagram data and foundation position data to the server device 200, the data receiving unit 120 receives the construction report data from the server device 200, and the data display unit 130 displays the construction report data. The foundation position data is, for example, generated and stored by the user themselves using the user terminal 100.

[0074] (Details of the functional configuration of the construction management terminal 300 according to the embodiment) When a user guides the construction machine to the pile center position and prepares a construction report, the data receiving unit 310 receives reinforcement body position data, guidance sequence data, and construction process management data from the server device 200. The data receiving unit 310 also receives satellite positioning data indicating the current position of the construction machine from the satellite positioning system via the positioning equipment described above.

[0075] The data display unit 320 displays the reinforcement body position data, guidance sequence data, construction process management data, and satellite positioning data received by the data receiving unit 310. The data generation unit 330 generates construction performance data each time the construction machine buryes a reinforcement body. The data transmission unit 340 transmits the construction performance data to the server device 200 each time the data generation unit 330 generates the construction performance data.

[0076] (Regarding the design study data generation process related to Embodiment 1) Next, the operation of the server device 200 to support the design review work for ground improvement will be explained using a flowchart. When the power is turned on, the server device 200 starts executing the design review data generation process shown in Figure 8. First, the data receiving unit 210 receives the ground investigation survey data and the building design drawing data from the user terminal 100 and stores them in the data storage unit 250 (step S101). After receiving the data, the data extraction unit 220 extracts Wsw data and Nsw data for all measurement points from the ground investigation survey data, and also extracts foundation area data from the building design drawing data (step S102).

[0077] After data extraction, the data generation unit 230 generates design study data, including minimum installation number data and maximum installation interval data, based on the Wsw data, Nsw data, base area data, and reliability calculation formula data, and stores it in the data storage unit 250 (step S103). Then, the data transmission unit 240 transmits the design study data to the user terminal 100 (step S104), and the process ends.

[0078] (Regarding the data generation process for the reinforcement arrangement diagram related to Embodiment 1) Next, the operation of the server device 200 in assisting the creation of the reinforcement arrangement diagram will be explained using a flowchart. When the power is turned on, the server device 200 starts executing the reinforcement arrangement diagram data generation process shown in Figure 9. First, the data receiving unit 210 receives the design study data, building design drawing data, and installation condition data from the user terminal 100 and stores them in the data storage unit 250 (step S201). After receiving the data, the data extraction unit 220 extracts the minimum number of installation data and the maximum installation interval data from the design study data, and also extracts the foundation plan data from the building design drawing data (step S202).

[0079] After data extraction, the data generation unit 230 places the reinforcing bodies on the foundation plan view indicated by the foundation plan view data at installation intervals less than or equal to the maximum pitch indicated by the maximum installation interval data, according to each installation condition indicated by the installation condition data (step S203). After placing the reinforcing bodies, the data generation unit 230 counts the number of reinforcing bodies placed on the plan view (step S204) and determines whether the counted number of installed bodies is equal to or greater than the minimum number of installed bodies (step S205). If the counted number of installed bodies is less than the minimum number of installed bodies (step S105; N), the data generation unit 230 returns to step S203 and repeats the process from steps S203 to S205. At this time, in step S203, the data generation unit 230 places the reinforcing bodies in positions different from the previous placement, as long as it follows each installation condition indicated by the installation condition data.

[0080] On the other hand, if the counted number of installed units is equal to or greater than the minimum number of units to be installed (step S205; Y), the data generation unit 230 uses a plan view in which the reinforcing units are arranged as the reinforcing unit arrangement diagram to generate reinforcing unit arrangement diagram data showing the said arrangement diagram, and stores it in the data storage unit 250 (step S206). Then, the data transmission unit 240 transmits the reinforcing unit arrangement diagram data to the user terminal 100 (step S207), and the process ends.

[0081] Furthermore, for the server device 200 to assist with construction estimation work, the data receiving unit 210 receives reinforcement body layout diagram data and construction cost data from the user terminal 100, the data generation unit 230 generates estimation data based on this data, and the data transmission unit 240 simply transmits the estimation data to the user terminal 100. In addition, for the server device 200 to assist with the guidance of the construction machine to the pile center position, the data receiving unit 210 receives reinforcement body layout diagram data and foundation position data from the user terminal 100, the data generation unit 230 generates reinforcement body position data, guidance sequence data and construction process management data based on this data, and the data transmission unit 240 simply transmits the reinforcement body position data, guidance sequence data and construction process management data to the construction management terminal 300.

[0082] Furthermore, the server device 200's operation to assist in the creation of construction reports simply involves the data receiving unit 210 receiving construction performance data from the construction management terminal 300, the data generation unit 230 generating construction report data based on the construction performance data, and the data transmission unit 240 transmitting the construction report data to the user terminal 100. Therefore, to reduce redundant explanations, the illustrations and detailed explanations of the server device 200's data generation processes are omitted.

[0083] As described above, according to the ground improvement construction support system 1 of this embodiment, as shown in Figure 10, when a user performs ground improvement design review work, the user terminal 100 transmits the ground investigation survey data and building design drawing data that the user has acquired in advance to the server device 200. After the server device 200 receives the ground investigation survey data and building design drawing data, it generates design review data based on this data and transmits it to the user terminal 100. After the user terminal 100 receives the design review data, it displays the design review data, allowing the user to visually check and edit it.

[0084] Subsequently, when the user terminal 100 performs the task of creating a reinforcement arrangement diagram, it transmits the previously acquired and edited design study data, building design drawing data, and installation condition data to the server device 200. The server device 200, after receiving the design study data, building design drawing data, and installation condition data, generates reinforcement arrangement diagram data based on this data and transmits it to the user terminal 100. After receiving the reinforcement arrangement diagram data, the user terminal 100 displays the data, allowing the user to visually confirm and edit it.

[0085] Subsequently, when the user terminal 100 performs construction cost estimation work, it transmits the previously acquired and edited reinforcement body layout data and construction cost data to the server device 200. After the server device 200 receives the reinforcement body layout data and construction cost data, it generates estimate data based on this data and transmits it to the user terminal 100. After the user terminal 100 receives the estimate data, it displays the estimate data, allowing the user to visually confirm and edit it.

[0086] Subsequently, when the user terminal 100 performs the task of guiding the construction machine to the pile center position and creating a construction report, it transmits the previously acquired and edited reinforcement body layout diagram data and foundation position data to the server device 200. After receiving the reinforcement body layout diagram data and foundation position data, the server device 200 generates reinforcement body position data, guidance sequence data, and construction process management data based on this data and transmits them to the construction management terminal 300. After receiving the reinforcement body position data, guidance sequence data, and construction process management data, the construction management terminal 300 displays this data while receiving satellite positioning data from the satellite positioning system. Furthermore, each time the construction machine buries a reinforcement body, the construction management terminal 300 generates construction performance data and transmits it to the server device 200. After receiving the construction performance data for all reinforcement bodies, the server device 200 generates construction report data based on this data and transmits it to the user terminal 100. After receiving the construction report data, the user terminal 100 displays the construction report data, allowing the user to visually review and edit it.

[0087] In this way, the ground improvement work support system 1 according to this embodiment can provide support for the series of tasks described above in ground improvement work using the server device 200. Furthermore, in this way, the ground improvement work support system 1 according to this embodiment can have the server device 200 automatically generate various files that are deliverables for each task and output them to the user terminal 100 used by the user. As a result, the ground improvement work support system 1 according to this embodiment can reduce the burden on the workers of the construction company, who are the users of the ground improvement work, as well as the working time and costs, compared to a ground improvement work support system in which the server device cannot automatically generate and output various data that are deliverables for each task. In addition, by optimizing the control of the server device 200, the ground improvement work support system 1 according to this embodiment can improve the quality of the various data described above that are automatically generated and output by the server device 200 without requiring the workers of the construction company, who are the users, to have advanced specialized knowledge or high skill levels.

[0088] Furthermore, according to the ground improvement work support system 1 of this embodiment, the server device 200 receives design study data, building design drawing data, and installation condition data from the user terminal 100, which are generated based on the ground investigation survey data. The data extraction unit 220 extracts the minimum number of installation data and the maximum installation interval data from the design study data, and also extracts the foundation plan data from the building design drawing data. The data generation unit 230 generates reinforcement arrangement diagram data, which shows the arrangement of reinforcement bodies on the foundation plan with a number of reinforcement bodies equal to or greater than the minimum number of installation bodies, while satisfying the installation conditions and with an installation interval of less than or equal to the maximum pitch, based on the installation condition data acquired by the data receiving unit 210 and the minimum number of installation data, maximum installation interval data, and foundation plan data extracted by the data extraction unit 220. The data transmission unit 240 then outputs the reinforcement arrangement diagram data generated by the data generation unit 230 to the user terminal 100.

[0089] In this way, when the server device 200 receives design study data, building design drawing data, and installation condition data from the user terminal 100, it can automatically generate reinforcement body layout diagram data based on the data extracted from these data and the installation condition data, and transmit it to the user terminal 100. As a result, the ground improvement work support system 1 according to this embodiment can reduce the burden on the user, working time, and working costs in ground improvement work compared to a ground improvement work support system that cannot automatically generate and output reinforcement body layout diagram data.

[0090] In particular, according to the ground improvement work support system 1 of this embodiment, if the number of reinforced bodies installed after placement, which is counted after placing the reinforced bodies on the plan view at intervals of less than or equal to the maximum pitch according to the installation conditions, is equal to or greater than the minimum number of installed bodies, the data generation unit 230 generates a layout diagram of the reinforced bodies based on the plan view in which the reinforced bodies are placed. In this way, the server device 200 can repeat the process of placing reinforcing bodies on the plan view in different arrangement patterns until more than the minimum number of reinforcing bodies are placed, as long as the reinforcing bodies are placed on the plan view at intervals of less than or equal to the maximum pitch according to the installation conditions.

[0091] (Example of change) In this embodiment, the user obtained various data, which are the deliverables of each task, by sending pre-acquired data to the server device 200 using the user terminal 100 and then receiving data transmitted from the server device 200. However, the embodiment is not limited to this. For example, the user may obtain various data, which are the deliverables of each task, by directly inputting pre-acquired data into a ground improvement construction support device equipped with similar functions to the server device 200 and then having the device output the data.

[0092] In this embodiment, the data generation unit 230 generates design study data using reliability calculation formula data showing the calculation formula described above, assuming that the contractor will perform ground improvement work using the screw press method, but it is not limited to this. For example, if the data generation unit 230 assumes that the contractor will perform ground improvement work using the conventionally known super narrow method, it may generate design study data using reliability calculation formula data showing the calculation formula for the long-term allowable bearing capacity of the reinforced ground in that method.

[0093] In this embodiment, in supporting the design review work for ground improvement, the data extraction unit 220 extracted Wsw data and Nsw data for all measurement points from the ground investigation survey data, but is not limited to this. For example, the data extraction unit 220 may also extract geological data from the ground investigation survey data that shows the "soil type" value for the rod penetration amount at 25 cm intervals for all measurement points. In this case, the data generation unit 230 may generate design review data including the minimum number of rods to be installed and the maximum spacing between rods to be installed, using not only the Wsw data, Nsw data, foundation area data, and reliability calculation formula data extracted by the data extraction unit 220, but also the geological data extracted by the data extraction unit 220.

[0094] In this embodiment, the data extraction unit 220 extracted foundation area data from building design drawing data in support of the ground improvement design review work, but is not limited to this. For example, the server device 200 may acquire foundation area data by receiving foundation area data transmitted from the user terminal 100. The foundation area data may include, for example, long-side data indicating the length of the long side of the foundation and short-side data indicating the length of the short side, generated by the user using the user terminal 100, and the server device 200 may calculate the value of the foundation area by multiplying the long-side and short-side values ​​indicated by the long-side data and short-side data. In this case, for example, if the foundation is not rectangular in shape, the calculated value of the foundation area will not be accurate, but as long as the error from the accurate value does not become too large, it is possible to generate design review data using the foundation area data.

[0095] In this embodiment, in supporting the design study work for ground improvement, the data generation unit 230 sets the maximum pitch value between reinforcing bodies indicated by the maximum installation interval data included in the design study data to 2.0m. However, it is not limited to this, and any value may be used as long as it is permissible in a predetermined construction method such as the screw press method. For example, the data generation unit 230 sets the maximum pitch value between reinforcing bodies to a value where the cross-sectional area A of the ground supported by the reinforcing bodies is 2.5m². 2 In this case, the user may set the maximum pitch to 1.85m, which is a smaller value than the value typically used when setting the maximum pitch, and the cross-sectional area A of the ground supported by the reinforcement is 2.5m². 2 In such cases, it is also possible to set a predetermined lower limit of 0.5m that can be set by the user. Furthermore, for example, if a predetermined special design condition is met, the data generation unit 230 will set the maximum pitch value between the reinforcing bodies to 2.5m when the cross-sectional area A of the ground supported by the reinforcing bodies is 2.5m 2 In this case, it is also possible to set a predetermined upper limit of 2.5m as the user-configurable limit.

[0096] In this embodiment, the data generation unit 230 generates data for the arrangement of reinforcing bodies on the plan shown in the foundation plan shown in the data, where the number of reinforcing bodies installed is equal to or greater than the minimum number of reinforcing bodies indicated by the minimum number of installation data, satisfies the installation conditions indicated by the installation conditions data, and is installed at intervals greater than or equal to the minimum pitch indicated by the minimum spacing data and less than or equal to the maximum pitch indicated by the maximum spacing data. However, the condition that the spacing must be greater than or equal to the minimum pitch indicated by the minimum spacing data may be omitted.

[0097] Furthermore, the server device 200 may, in assisting the creation of the reinforcement arrangement diagram, calculate the exact area value of the foundation from the foundation plan shown in the foundation plan data extracted from the building design drawing data. In this case, if the foundation area data included in the design study data is not accurate as described above, the data generation unit 230 may generate foundation area data based on the calculated accurate foundation area value and update the data stored in the data storage unit 250. In this case, the data generation unit 230 may also generate design study data based on the updated foundation area data and update the data stored in the data storage unit 250, or generate reinforcement arrangement diagram data based on the updated design study data and update the data stored in the data storage unit 250.

[0098] In this embodiment, when the server device 200 assists in the creation of reinforcement arrangement diagrams, it receives design study data, building design drawing data, and installation condition data each time reinforcement arrangement diagram data is generated, but it is not limited to this. For example, in this embodiment, when the server device 200 assists in the design study work for ground improvement, it stores the design study data and building design drawing data in the data storage unit 250, and since this data can be obtained from the data storage unit 250, it does not need to receive this data from the user terminal 100 when generating reinforcement arrangement diagram data. Also, for example, if the server device 200 has previously acquired installation condition data and stored it in the data storage unit 250, and the installation condition data can be obtained from the data storage unit 250, it does not need to receive the installation condition data from the user terminal 100 when generating reinforcement arrangement diagram data.

[0099] In this embodiment, when the server device 200 assists with construction estimation work, it receives reinforcement body layout data and construction cost data each time it generates estimation data, but it is not limited to this. For example, in this embodiment, when the server device 200 assists with the creation of reinforcement body layout data, it stores the reinforcement body layout data in the data storage unit 250, and since the reinforcement body layout data can be obtained from the data storage unit 250, it does not need to receive the reinforcement body layout data from the user terminal 100 when generating estimation data. Also, for example, if the server device 200 has previously obtained the construction cost data and stored it in the data storage unit 250, and the construction cost data can be obtained from the data storage unit 250, it does not need to receive the construction cost data from the user terminal 100 when generating estimation data.

[0100] In this embodiment, when the server device 200 assists in the guidance of the construction machine to the pile center position and the creation of construction reports, it receives reinforcement body layout data and foundation position data each time it generates reinforcement body position data and guidance sequence data, but it is not limited to this. For example, in this embodiment, when the server device 200 assists in the creation of the reinforcement body layout data, it stores the reinforcement body layout data in the data storage unit 250, and since the reinforcement body layout data can be obtained from the data storage unit 250, it is not necessary to receive the reinforcement body layout data from the user terminal 100 when generating the reinforcement body position data and guidance sequence data. Also, for example, if the server device 200 has previously acquired foundation position data and stored it in the data storage unit 250, and the foundation position data can be obtained from the data storage unit 250, it is not necessary to receive the construction cost data from the user terminal 100 when generating the reinforcement body position data and guidance sequence data.

[0101] Furthermore, the core part of the processing performed by the user terminal 100, server device 200, and construction management terminal 300, which are equipped with a control unit 51, main memory unit 52, external memory unit 53, operation unit 54, transmission / reception unit 56, and internal bus 50, may be configured by storing each program for executing the above operations on a recording medium readable by the user terminal 100, server device 200, and construction management terminal 300, such as flash memory, distributing them, and installing each program. Alternatively, each program may be stored in a storage device on a server device on a communication network such as a LAN or the Internet, and the user terminal 100, server device 200, and construction management terminal 300 may be configured by downloading each program.

[0102] Furthermore, if the functions of the user terminal 100, server device 200, and construction management terminal 300 are realized through the division of responsibilities between the OS and application programs, or through the cooperation of the OS and application programs, then only the application program portion may be stored on a recording medium or storage device.
