[0001] The present invention relates to a ground improvement work support system, a ground improvement work support device, a control method, and a program. [Background technology]

[0002] Conventionally, in ground improvement work, contractors are required to perform a series of tasks, such as conducting ground surveys, designing the ground improvement, creating layout diagrams of reinforcement bodies to be used in the ground improvement, estimating the work, managing the construction process, guiding the construction machine to the pile core position, and preparing a construction report. These tasks require a large number of workers, who manually perform tasks such as manually entering data into computer systems, completing paperwork, and visually inspecting the site. To achieve high-precision work, the workers must have a high level of expertise and proficiency. Therefore, there is a need to significantly automate and optimize these tasks using 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 a pile core position based on location information obtained from a satellite positioning system such as a 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 for the site at the construction site, and then executes the construction management program using the setting parameters and planning data to manage the process of burying multiple steel pipe piles in order at each pile core position. In Patent Document 1, the construction management device generates construction performance data and transmits it to a data server each time it finishes burying each steel pipe pile, and a personal computer (PC) in the management office creates a report based on the construction performance data obtained from the data server.

The system includes: a data extraction unit that extracts minimum number data and maximum installation interval data that indicates a maximum installation interval that is the maximum installation interval between the reinforcements, and extracts foundation plan data that indicates a plan view of the foundation from the building design plan data; a data generation unit that generates reinforcement arrangement plan data that indicates an arrangement plan of the reinforcements, where the number of reinforcements installed is equal to or greater than the minimum installation number and is arranged on the plan view at an installation interval that is equal to or less than the maximum installation interval while satisfying the installation conditions, based on the installation condition data acquired by the data acquisition unit, the minimum installation number data, the maximum installation interval data, and the foundation plan data extracted by the data extraction unit; and a data output unit that outputs the reinforcement arrangement plan data generated by the data generation unit to the user terminal. [Effects of the Invention]

[0026] (Details of Functional Configuration of Server Device 200 According to the Embodiment) [Support for ground improvement design review work] First, the support for the work of examining the design of ground improvement performed by the server device 200 will be described below.

[0027] The data receiving unit 210 receives from the user terminal 100 ground investigation result data indicating the results of a ground investigation of the foundation and building design plan data indicating the design plan of the building, and stores these in the data storage unit 250. Here, the ground investigation result data is data indicating the results of an investigation of five predetermined measurement points on the ground within the scope of the foundation, for example, as a result of a conventionally known test known as a Swedish sounding test or a screw weight penetration test (hereinafter referred to as an "SWS test"). Note that, although the present embodiment illustrates an example in which a ground investigation is conducted at five measurement points, the number of measurement points for the ground investigation is not limited to this and may be four or less, or six or more.

[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 19 mm outer diameter rod. The minimum load at which the rod sinks at each measurement point in the ground at a load of 1.00 kN or less is recorded as Wsw. Furthermore, in the SWS test, when the rod no longer sinks even at a load of 1.00 kN, the rod is rotated and the number of rotations per 180° required to penetrate 0.25 m, i.e., the number of half rotations, is measured as Na. The number of half rotations, Na, is converted to the number of half rotations per meter of penetration and recorded as Nsw.

[0029] For example, the ground survey result data can be displayed in the form of a table as shown in Figure 4, and includes items and their values, such as a "survey date and time" indicating the date and time of the survey and "latitude and longitude" indicating the latitude and longitude of the survey point, for each item, "survey point number," which indicates the identification number of the survey point. For example, as shown in Figure 4, the ground survey result 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: 3644.XXXA (36°44'A.BB") East: 13702.YYYA (137°2'CC.DD")."

[0030] The ground survey result data includes, for each "measurement point number" item, the following items and their values: "Penetration depth D (m)" indicating the rod penetration depth D [m], "Load Wsw (kN)" indicating the minimum load Wsw [kN], "Number of half rotations Na (times)" indicating the number of half rotations Na [times], "Number of half rotations per meter Nsw (times)" indicating the number of half rotations Nsw [times] per meter, and "Soil quality" indicating the geology. As shown in Figure 4, the ground survey result data includes values ​​for the items "Penetration depth D (m)," "Load Wsw (kN)," "Number of half rotations Na (times)," and "Number of half rotations per meter Nsw (times)" for every 25 cm of rod penetration. For example, the ground survey results data includes data such as "Measurement point number" being "1," "Penetration depth D (m)" being "0.25," "Load Wsw (kN)" being "0.50," "Self-sinking" indicating that the number of half rotations Na (times) is 0, "Number of half rotations per meter Nsw (times)" is "0," and "Soil type" being "clayey," indicating that the soil is clayey.

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

[0032] The data format of the soil survey result data may be any format such as a document format, a graphic format, a spreadsheet format, etc. For example, if the file in which the soil survey result data is saved is a graphic format file such as a PDF (registered trademark) file, the data extraction unit 220 may extract the Wsw data and Nsw data using a technology for recognizing characters in graphics such as OCR (registered trademark) (Optical Character Recognition).

[0033] The data extraction unit 220 also extracts foundation area data indicating the area of ​​the foundation from the building design data stored in the data storage unit 250. The building design data may be data generated in a data format with any file extension that can be read, generated, edited, and controlled by various types of CAD (Computer-Aided Design) software. For example, the data extraction unit 220 extracts "72.5m" from the building design data (not shown). 2 If data that can identify the area of ​​the foundation, such as ", is included, the data is extracted as foundation area data.

[0034] The data generation unit 230 generates design review data including minimum number of reinforcement elements data and maximum installation interval data (described later) based on various data extracted by the data extraction unit 220, such as the Wsw data, Nsw data, and foundation area data, as well as reliability calculation formula data and minimum installation interval data (described later), and stores the generated design review data in the data storage unit 250. The minimum number of reinforcement elements data included in the generated design review data indicates the minimum number of reinforcement elements, which is the minimum number of reinforcement elements to be installed. The maximum installation interval data indicates the maximum installation interval, or maximum pitch, which is the maximum installation interval between reinforcement elements. The reliability calculation formula data used to generate the design review data indicates a reliability calculation formula for ground improvement based on a predetermined construction method. The minimum installation interval data indicates the minimum installation interval, or minimum pitch, which is the minimum installation interval between reinforcement elements. In this embodiment, the minimum pitch is predetermined to 0.5 m. Furthermore, the reliability calculation formula for ground improvement indicated by the reliability calculation formula data is, for example, a formula for calculating the long-term allowable bearing capacity of reinforced ground in the conventionally known screw press method, and specifically, is the formula shown in the following equation 1.

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

[0036] In the above-mentioned formula 1, q a is the long-term allowable bearing capacity of the reinforced ground (kN / m 2 ) and q sa is the long-term allowable bearing capacity of the ground (original ground) before reinforcement (kN / m 2 ) and q pa is the long-term allowable bearing capacity of the reinforcement body (kN / m 2 ) In addition, in the above calculation formula, a s is the improvement rate of the ground due to the reinforcement body, specifically, the cross-sectional area A p The value of (m 2 ) is calculated by dividing the cross-sectional area A of the ground that the reinforcement body bears by the 2) divided by (A p / A).

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

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

[0039] Therefore, the long-term allowable bearing capacity of the original ground q sa Value (kN / m 2 ) can be calculated based on the values ​​indicated by the Wsw data and Nsw data, for example, 23.14 kN / m 2 In addition, the long-term allowable bearing capacity of the reinforcement body q pa Value (kN / m 2 ) is preset, for example, 230 kN / m 2 is.

[0040] Therefore, the long-term allowable bearing capacity of the reinforced ground q a Value (kN / m 2 ) is set to a sufficient value based on the building, the improvement rate of the reinforcement a s In addition, the cross-sectional area A of the reinforcement body can be calculated. p The value of (m 2 ) is also preset, for example, if the outer diameter of the cylindrical reinforcing body is 430 mm, it is about 0.145 m 2 (3.14 (0.215) 2 ≒0.145 m 2 ]. Therefore, the improvement rate of the reinforcement a s When the value of the cross-sectional area A of the ground to be borne by the reinforcement body is calculated, 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 In this case, the improvement rate of the reinforcement a s , and 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 ]) holds.

[0041] Therefore, the long-term allowable bearing capacity of the reinforced ground is q a The value is 35.14kN / m 2 If this is sufficient, then one reinforcement body with a cross-sectional area A of 2.5m 2 It can be seen that the ground can be reinforced. In addition, the cross-sectional area A of the ground that the reinforcement body can support is 2 ) is calculated, the area of ​​the foundation indicated by the foundation area data (m 2 ) can be used to calculate the minimum number of reinforcement bodies to be installed. For example, if the foundation area is 72.5 m 2 In this case, the minimum number of reinforcement elements to be installed is 29 (72.5 / 2.5=29). The maximum pitch between reinforcement elements is also calculated based on the cross-sectional area A of the ground (m 2 ), the minimum number of poles to be installed (pole), the area of ​​the foundation (m 2 ), and minimum pitch (0.5m). For example, the maximum pitch between reinforcement bodies must be at least the minimum pitch (0.5m), and the cross-sectional area A of the ground supported by the reinforcement body must be 2.5m. 2 In this case, the maximum pitch may be set to 2.0 m, which is a predetermined value that is normally used when the user sets the maximum pitch.

[0042] The data generating unit 230 acquires the reliability calculation formula data and the minimum installation interval data stored in the data storage unit 250. The data generating unit 230 also acquires the reliability calculation formula data and the minimum installation interval data stored in the data storage unit 250. The data generating unit 230 also acquires the reliability calculation formula data and the minimum installation interval data stored in the data storage unit 250. a ,q pa ,A pand the minimum pitch value (0.5 m) indicated by the minimum installation interval data, the minimum number of reinforcement members to be installed (number of reinforcement members) and the maximum pitch value (m) between reinforcement members are identified 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 review document data including the minimum installation number data and the maximum installation interval data, and stores them in the data storage unit 250.

[0043] For example, the design review document data is data that can be displayed in the form of a table as shown in Figure 5, and is data that includes, for each measurement point, items such as "Wsw" indicating Wsw data and "Nsw" indicating Nsw data, and their values ​​(values ​​for every 25 cm of the rod penetration amount mentioned above). For example, as shown in Figure 5, the design review document data includes data such as "No. 1" indicating that the "measurement point number" is "1," and when the "investigation depth" indicating the "penetration depth D (m)" is "0.25," "Wsw" is "0.50" and "Nsw" is "0."

[0044] For example, the design review data includes the "base area of ​​the foundation (m 2 The data includes items and their values, such as "base area of ​​foundation" of "72.5", "maximum pitch (m)" which indicates the maximum installation interval data, and "number of installed pieces" which indicates the minimum number of installed pieces. For example, the design review data includes data such as "base area of ​​foundation" of "72.5", "maximum pitch (m)" of "2.0", and "number of installed pieces" of "29".

[0045] The design review document data includes the above-mentioned minimum installation number data and maximum installation interval data, but is not limited to this. For example, the design review document data may include minimum installation interval data indicating the minimum pitch. Furthermore, for example, the design review document data may include determination result data indicating the determination result of the reliability of the ground improvement work based on the minimum installation number data and the maximum installation interval data. Furthermore, for example, the design review document data may also include various data such as foundation area data identified from the building design drawing data, 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 review document data generated by the data generation unit 230 to the user terminal 100 .

[0047] [Support for creating reinforcement structure layout diagrams] Next, support for the creation of a layout drawing of a reinforcement body performed by the server device 200 will be described below.

[0048] The data receiving unit 210 receives from the user terminal 100 design review data, building design drawing data, and installation condition data indicating installation conditions for reinforcement bodies used in ground improvement generated based on a predetermined construction method, and stores these in the data storage unit 250. The installation condition data, which will be described in detail later, is data indicating conditions that a contractor must follow when installing a reinforcement body predetermined by the contractor, assuming compliance with the above-mentioned construction method. Note that the data received by the data receiving unit 210 may have been changed from the data stored in the data storage unit 250 by a user input using the user terminal 100. Therefore, if the data stored in the data storage unit 250 differs from the data received from the user terminal 100, the data storage unit 250 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 review document data stored in the data storage unit 250. The data extraction unit 220 also extracts foundation plan data showing the plan view of the foundation from the building design plan data stored in the data storage unit 250.

[0050] The foundation plan data is data capable of displaying, for example, the plan shown by the solid line in FIG. 6. The data extraction unit 220 extracts the foundation plan data from the building design data by generating data representing a plan view, which is a line drawing connecting the intermediate line between the line indicating the outer surface of the exterior wall shown by the dashed-dotted line in FIG. 6 and the line indicating the inner surface shown by the dashed-two-dotted line in FIG. 6, based on the building design data. The foundation plan data, like the building design data, may be data generated in a data format with any file extension that can be handled by various CAD software. The data extraction unit 220 may also convert the data format using known software, such as a CAD converter, in order to extract the foundation plan data from the building design data.

[0051] The data generation unit 230 generates reinforcement element layout plan data showing an layout plan of reinforcements based on the installation condition data stored in the data storage unit 250, and the minimum installation number data, maximum installation interval data, and base plan data extracted by the data extraction unit 220. The data generation unit 230 generates reinforcement element layout plan data in which reinforcements are installed in a number equal to or greater than the minimum installation number indicated by the minimum installation number data, and are arranged on the plan shown by the base plan data at an installation interval equal to or less than the maximum pitch indicated by the maximum installation interval data, while satisfying the installation conditions indicated by the installation condition data, and stores the generated data in the data storage unit 250.

[0052] The installation condition data includes, for example, data indicating a first installation condition that requires the central axis of a reinforcement body to be shifted inward from the foundation line so that the outer peripheral surface of the reinforcement body, which has a circular cross section, is positioned in a position where it is in contact with the outer surface of the exterior wall of the building, which has a linear cross section, on a plan view. The installation condition data also includes, for example, data indicating a second installation condition that requires reinforcement bodies to be placed at 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 that requires reinforcement bodies to be placed as much as possible when there is an intersection between a line passing through the central axes of two or more reinforcement bodies placed at adjacent corners and a line of the foundation. The installation condition data also includes, for example, data indicating a fourth installation condition that requires reinforcement bodies to be placed as evenly spaced as possible in areas other than the above-mentioned corners.

[0053] First, the data generation unit 230 arranges the reinforcements on the plan view at an installation interval equal to or less than the maximum pitch in accordance with each installation condition indicated by the installation condition data, counts the number of reinforcements arranged on the plan view, and determines whether the counted number is equal to or greater than the minimum installation number. If the counted number is equal to or greater than the minimum installation number, the data generation unit 230 sets the plan view on which the reinforcements are arranged as a reinforcement arrangement view, thereby generating reinforcement arrangement view data indicating the arrangement view and storing the data in the data storage unit 250.

[0054] The reinforcement arrangement plan data is data that can display, for example, the plan view shown by the solid line in Fig. 7. The data generating unit 230 arranges the reinforcement so that the outer peripheral surface of the circular reinforcement shown by the solid line in Fig. 7 is in contact with the outer surface of the outer wall shown by the dashed line in Fig. 7, for example, in accordance with the first installation condition. For example, if the thickness of the outer wall is 150 mm, the distance between the line of the foundation and the line of the outer surface of the outer wall is 75 mm (150 / 2 = 75 [mm]), and 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]) inside the line of the foundation.

[0055] Furthermore, the data generation unit 230, for example, according to the second installation condition, places the reinforcing members indicated by "1" in a solid circle in FIG. 7 at five convex corners and one concave corner of the foundation. Furthermore, according to the third installation condition, for example, the data generation unit 230 places the reinforcing members indicated by "2" in a solid circle in FIG. 7 at the middle of the straight line of the foundation. Furthermore, according to the fourth installation condition, for example, the data generation unit 230 places the reinforcing members indicated by "3" in a solid circle in FIG. 7 at the middle of the straight line of the foundation, as evenly spaced as possible at an installation interval that is equal to or less than the maximum pitch. Thereafter, according to the fourth installation condition, for example, the data generation unit 230 places the reinforcing members indicated by "4" in a solid circle in FIG. 7 at the inner part of the foundation, as evenly spaced as possible at an installation interval that is equal to or less than the maximum pitch.

[0056] The data generation unit 230 then counts the number of reinforcement elements arranged on the floor plan to determine that it is 34, and determines that the count of 34 is equal to or greater than the minimum number of reinforcement elements, which is 29. Therefore, the data generation unit 230 can generate reinforcement element layout plan data showing the layout of the reinforcement elements, which is a floor plan showing a total of 34 reinforcement elements, and store the data in the data storage unit 250. Note that, like the building design plan data and the foundation plan data, the reinforcement element layout plan data may be generated in a data format with any file extension that can be handled by various CAD software. Furthermore, the data generation unit 230 may convert the data format using, for example, a CAD converter, in order to generate the reinforcement element layout plan data from the foundation plan data.

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

[0058] [Support for construction estimate work] Next, the support for construction estimate work performed by the server device 200 will be described below.

[0059] The data receiving unit 210 receives reinforcement body layout plan data and construction cost data relating to the construction costs of burying the reinforcement bodies from the user terminal 100, and stores them in the data storage unit 250. Here, the construction cost data is data including, for example, burial cost data indicating the unit price per reinforcement body as an example of the cost required to bury the reinforcement body. Note that if the data stored in the data storage unit 250 differs from the data received from the user terminal 100, the data storage unit 250 updates it to 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 element layout plan data and construction cost data stored in the data storage unit 250. For example, the data generation unit 230 first counts the number of installed reinforcement elements arranged in the layout plan shown in the reinforcement element layout plan data, and identifies the unit cost per reinforcement element from the embedded unit cost data included in the construction cost data. The data generation unit 230 then calculates an amount by multiplying the number of installed reinforcement elements by the unit cost, and generates estimate data including estimate amount data showing the calculated estimated amount.

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

[0062] [Management of construction process and support for guiding construction machinery to the pile core position] Next, the management of the construction process and the support for the work of guiding the construction machine to the pile core position performed by the server device 200 will be described below.

[0063] The data receiving unit 210 receives reinforcement body layout plan 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, the data storage unit 250 updates it to the data received from the user terminal 100.

[0064] The data generation unit 230 generates reinforcement element position data that can identify the latitude and longitude of the central axes of all reinforcement elements arranged on the layout plan, based on the reinforcement element layout plan data and foundation position data stored in the data storage unit 250. Furthermore, the data generation unit 230 generates guidance order data that indicates the guidance order, which is the order in which the construction machine is guided to bury the reinforcement elements, based on the generated reinforcement element 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 element position data and the guidance order 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, the guidance order data, and the construction process management data generated by the data generation unit 230 to the construction management terminal 300.

[0066] [Support for creating construction reports] Next, support for the creation of a construction report performed by the server device 200 will be described below.

[0067] The data receiving unit 210 receives construction performance data indicating the performance of burying the reinforcing body from the construction management terminal 300, and stores the data in the data storage unit 250. The construction performance data includes, for example, data indicating the time, latitude, and longitude of burying each reinforcing body.

[0068] The data generating unit 230 generates construction report data indicating 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 Functional Configuration of User Terminal 100 According to the Embodiment) When a user performs a ground improvement design review work, the data transmission unit 110 transmits previously acquired ground survey result data and building design drawing data to the server device 200, and the data reception unit 120 receives the design review document data from the server device 200. In this case, the data display unit 130 displays, for example, the design review document data shown in FIG.

[0071] Furthermore, when a user creates a layout plan of a reinforcement body, the data transmission unit 110 transmits the design review document data, building design plan data, and installation condition data acquired in advance to the server device 200, and the data reception unit 120 receives the reinforcement body layout plan data from the server device 200. In this case, the data display unit 130 displays, for example, the reinforcement body layout plan data shown by the solid line in Fig. 7. Note that the installation condition data is, for example, generated and stored by the user himself / herself using the user terminal 100.

[0072] Furthermore, when a user performs construction work estimation work, the data transmission unit 110 transmits the reinforcement body layout plan data and construction cost data acquired in advance 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 himself / herself using the user terminal 100.

[0073] Furthermore, when the user guides the construction machine to the pile core position and creates a construction report, the data transmission unit 110 transmits the reinforcement arrangement diagram data and foundation position data acquired in advance to the server device 200, the data reception unit 120 receives the construction report data from the server device 200, and the data display unit 130 displays the construction report data. Note that the foundation position data is, for example, generated and stored by the user himself using the user terminal 100.

[0074] (Details of the functional configuration of the construction management terminal 300 according to the embodiment) When the user guides the construction machine to the pile core position and creates a construction report, the data receiving unit 310 receives reinforcement body position data, guidance order 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 above-mentioned positioning equipment.

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

[0076] (Regarding the design review document data generation process according to the first embodiment) Next, the operation of the server device 200 to support the work of reviewing the design of ground improvement will be described using a flowchart. When the server device 200 is powered on, it starts executing the design review document data generation process shown in Fig. 8. First, the data receiving unit 210 receives the ground investigation result data and the building design plan data from the user terminal 100 and stores them in the data storage unit 250 (step S101). After receiving the data, the data extracting unit 220 extracts the Wsw data and Nsw data at all measurement points from the ground investigation result data and extracts the foundation area data from the building design plan data (step S102).

[0077] After the data extraction, the data generation unit 230 generates design review document data including the minimum number of trees to be installed and the maximum spacing between trees based on the Wsw data, Nsw data, foundation area data, and reliability calculation formula data, and stores the data in the data storage unit 250 (step S103). Then, the data transmission unit 240 transmits the design review document data to the user terminal 100 (step S104), and the process ends.

[0078] (Regarding the reinforcement member layout diagram data generation process according to the first embodiment) Next, an operation of the server device 200 to support the creation of a reinforcement body layout plan will be described using a flowchart. When the server device 200 is powered on, it starts executing the reinforcement body layout plan data generation process shown in Fig. 9. First, the data receiving unit 210 receives design review document data, building design plan 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 extracting unit 220 extracts minimum installation number data and maximum installation interval data from the design review document data, and extracts foundation floor plan data from the building design plan data (step S202).

[0079] After the data extraction, the data generation unit 230 arranges the reinforcing elements on the foundation plan shown by the foundation plan data at an installation interval equal to or less than the maximum pitch indicated by the maximum installation interval data, in accordance with each installation condition indicated by the installation condition data (step S203). After arranging the reinforcing elements, the data generation unit 230 counts the number of reinforcing elements arranged on the plan view (step S204) and determines whether the counted number is equal to or greater than the minimum installation number (step S205). If the counted number is less than the minimum installation number (step S105; N), the data generation unit 230 returns to step S203 and repeats the processes of steps S203 to S205. At this time, in step S203, the data generation unit 230 arranges the reinforcing elements at a position different from the previous arrangement, as long as it complies with each installation condition indicated by the installation condition data.

[0080] On the other hand, if the counted number of installed reinforcements is equal to or greater than the minimum number of installed reinforcements (step S205; Y), the data generation unit 230 generates reinforcement element layout plan data showing the layout plan by using the plan view in which the reinforcements are arranged as a layout plan of the reinforcements, and stores the data in the data storage unit 250 (step S206). Then, the data transmission unit 240 transmits the reinforcement element layout plan data to the user terminal 100 (step S207), and the process ends.

[0081] In addition, with regard to the operation of the server device 200 to support the construction estimate work, the data receiving unit 210 simply receives reinforcement body layout plan data and construction cost data from the user terminal 100, the data generating unit 230 generates estimate data based on these data, and the data transmitting unit 240 transmits the estimate data to the user terminal 100. In addition, with regard to the operation of the server device 200 to support the work of guiding a construction machine to a pile core position, the data receiving unit 210 simply receives reinforcement body layout plan data and foundation position data from the user terminal 100, the data generating unit 230 generates reinforcement body position data, guidance order data, and construction process management data based on these data, and the data transmitting unit 240 transmits the reinforcement body position data, guidance order data, and construction process management data to the construction management terminal 300.

[0082] Furthermore, the operation of the server device 200 to support the creation of a construction report simply involves the data receiving unit 210 receiving construction performance data from the construction management terminal 300, the data generating unit 230 generating construction report data based on the construction performance data, and the data transmitting unit 240 transmitting the construction report data to the user terminal 100. Therefore, in order to reduce redundant explanation, illustrations and detailed explanations of the process of generating these data by the server device 200 will be omitted.

[0083] As described above, according to the ground improvement work support system 1 of this embodiment, as shown in Fig. 10, when a user performs work to review the design of ground improvement work, the user terminal 100 transmits ground survey result data and building design plan data previously acquired by the user to the server device 200. After receiving the ground survey result data and the building design plan data, the server device 200 generates design review document data based on these data and transmits it to the user terminal 100. After receiving the design review document data, the user terminal 100 displays the design review document data, allowing the user to visually check, edit, etc.

[0084] Thereafter, when the user performs work to create a layout plan of a reinforcement body, the user terminal 100 transmits the design review document data, building design drawing data, and installation condition data that have been previously acquired and edited to the server device 200. After receiving the design review document data, building design drawing data, and installation condition data, the server device 200 generates reinforcement body layout plan data based on these data and transmits it to the user terminal 100. After receiving the reinforcement body layout plan data, the user terminal 100 displays the reinforcement body layout plan data, allowing the user to visually check, edit, etc.

[0085] Thereafter, when the user performs construction estimate work, the user terminal 100 transmits the reinforcement member layout plan data and construction cost data that have been previously acquired and edited to the server device 200. After receiving the reinforcement member layout plan data and the construction cost data, the server device 200 generates estimate data based on these data and transmits it to the user terminal 100. After receiving the estimate data, the user terminal 100 displays the estimate data, allowing the user to visually check, edit, etc.

[0086] Thereafter, when the user guides the construction machine to the pile core position and prepares a construction report, the user terminal 100 transmits to the server device 200 the reinforcement body arrangement plan data and foundation position data that have been previously acquired and edited. After receiving the reinforcement body arrangement plan data and foundation position data, the server device 200 generates reinforcement body position data, guidance order data, and construction process management data based on these data and transmits them to the construction management terminal 300. After receiving the reinforcement body position data, guidance order data, and construction process management data, the construction management terminal 300 displays these data while receiving satellite positioning data from the satellite positioning system. The construction management terminal 300 generates construction record data each time the construction machine buries a reinforcement body and transmits it to the server device 200. After receiving the construction record data for all reinforcements, the server device 200 generates construction report data based on these 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 check, edit, and so on.

[0087] In this way, the ground improvement work support system 1 according to this embodiment can provide support for the above-mentioned series of tasks 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 automatically generate various files that are deliverables for each task using the server device 200 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, work time, and work costs on the construction contractor's workers (users) in the ground improvement work 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. Furthermore, the ground improvement work support system 1 according to this embodiment can improve the quality of the above-mentioned various data that are automatically generated and output by the server device 200, without requiring the construction contractor's workers (users) to have advanced specialized knowledge or high proficiency, by optimizing the control of the server device 200.

[0088] Furthermore, in the ground improvement work support system 1 according to this embodiment, the data receiving unit 210 in the server device 200 receives from the user terminal 100 the design review document data, building design plan data, and installation condition data generated based on the ground survey result data. The data extracting unit 220 extracts the minimum number of installation units and the maximum installation interval data from the design review document data, and extracts the foundation plan data from the building design plan data. The data generating unit 230 generates reinforcement arrangement plan data showing an arrangement of reinforcement units, in which the number of reinforcement units installed is equal to or greater than the minimum number and is arranged on the foundation plan at an installation interval equal to or less than the maximum pitch while satisfying the installation conditions, based on the installation condition data acquired by the data receiving unit 210, the minimum number of installation units and the maximum installation interval data, and the foundation plan data extracted by the data extracting unit 220. The data transmitting unit 240 then outputs the reinforcement arrangement plan data generated by the data generating unit 230 to the user terminal 100.

[0089] In this way, when the server device 200 receives the design review document data, building design drawing data, and installation condition data from the user terminal 100, it can automatically generate reinforcement body layout plan 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, work time, and work costs in ground improvement work compared to a ground improvement work support system that cannot automatically generate and output reinforcement body layout plan data.

[0090] In particular, according to the ground improvement work support system 1 of this embodiment, if the number of reinforcement bodies installed after placement counted after placing the reinforcement bodies on a plan view at an installation interval not exceeding the maximum pitch in accordance with the installation conditions is equal to or greater than the minimum number of reinforcement bodies to be installed, the data generation unit 230 generates a layout diagram of the reinforcement bodies based on the plan view on which the reinforcement bodies are placed. By doing this, the server device 200 can repeat the process of placing reinforcement bodies on the floor plan in different placement patterns until more than the minimum number of reinforcement bodies have been placed, as long as the reinforcement bodies are placed on the floor plan at an installation interval less than the maximum pitch in accordance with the installation conditions.

[0091] (Example of change) In the present embodiment, the user acquires various data that are the deliverables of each work by transmitting data acquired in advance to the server device 200 using the user terminal 100 and then receiving data transmitted from the server device 200, but this is not limiting. For example, the user may acquire various data that are the deliverables of each work by directly inputting the data acquired in advance into a ground improvement work support device having the same functions as the server device 200 and then having the device output the data.

[0092] In this embodiment, the data generating unit 230 generates the design review document data using the reliability calculation formula data indicating the above-mentioned calculation formula on the assumption that the contractor will carry out the ground improvement work using the screw press method, but the present invention is not limited to this. For example, if the data generating unit 230 assumes that the contractor will carry out the ground improvement work using the conventionally known super narrow method, the data generating unit 230 may generate the design review document data using the reliability calculation formula data indicating the formula for calculating the long-term allowable bearing capacity of the reinforced ground in that method.

[0093] In this embodiment, in supporting the work of reviewing the design of ground improvement work, the data extraction unit 220 extracts Wsw data and Nsw data at all measurement points from the ground survey result data, but this is not limiting. For example, the data extraction unit 220 may also extract geological data indicating the "soil quality" values ​​for every 25 cm of rod penetration at all measurement points from the ground survey result data. In this case, the data generation unit 230 may generate design review document data including minimum number of installations data and maximum installation spacing data 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 the present embodiment, in supporting the ground improvement design review work, the data extraction unit 220 extracts foundation area data from building design plan data. However, this is not limiting. 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 be data including 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. The server device 200 may calculate the foundation area value 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, the calculated foundation area value may be inaccurate, but it is possible to generate design review document data using the foundation area data as long as the error from the accurate value is not too large.

[0095] In this embodiment, in supporting the work of examining the design of ground improvement, the data generating unit 230 sets the value of the maximum pitch between reinforcement bodies indicated by the maximum installation interval data included in the design examination document data to 2.0 m, but this is not limited to this and any value may be set as long as it is allowed in a predetermined construction method such as the screw press construction method. For example, the data generating unit 230 sets the value of the maximum pitch between reinforcement bodies to 2.0 m when the cross-sectional area A of the ground supported by the reinforcement body is 2.5 m. 2 In this case, the user may set the maximum pitch to 1.85 m, which is a smaller value than the standard value, and the cross-sectional area A of the ground borne by the reinforcement body is 2.5 m 2 In this case, the lower limit that can be set by the user may be set to 0.5 m, which is predetermined. Also, for example, when a predetermined special design condition is met, the data generating unit 230 may set the maximum pitch value between reinforcing bodies to 0.5 m when the cross-sectional area A of the ground supported by the reinforcing bodies is 2.5 m. 2 In this case, the upper limit that can be set by the user may be set to 2.5 m, which is predetermined.

[0096] In this embodiment, the data generation unit 230 generates reinforcement arrangement plan data in which a number of reinforcement members equal to or greater than the minimum number indicated by the minimum installation number data is arranged on the floor plan indicated by the basic floor plan data at an installation interval equal to or greater than the minimum pitch indicated by the minimum installation spacing data and equal to or less than the maximum pitch indicated by the maximum installation spacing data, while satisfying the installation conditions indicated by the installation condition data; however, the condition of being equal to or greater than the minimum pitch indicated by the minimum installation spacing data may be omitted.

[0097] Furthermore, the server device 200 may calculate an accurate area value of the foundation from the plan view of the foundation indicated by the foundation plan data extracted from the building design plan data in supporting the creation of a reinforcement body layout plan. In this case, if the area value of the foundation indicated by the foundation area data included in the design review document data is inaccurate as described above, the data generation unit 230 may generate foundation area data based on the calculated accurate area value of the foundation and update the data stored in the data storage unit 250. In this case, the data generation unit 230 may generate design review document data based on the updated foundation area data and update the data stored in the data storage unit 250, or generate reinforcement body layout plan data based on the updated design review document data and update the data stored in the data storage unit 250.

[0098] In the present embodiment, when supporting the creation of a reinforcement body layout plan, the server device 200 receives the design review document data, the building design plan data, and the installation condition data each time reinforcement body layout plan data is generated. However, this is not limited to this. For example, in the present embodiment, the server device 200 stores the design review document data and the building design plan data in the data storage unit 250 when supporting the review work of the ground improvement design. Since these data can be acquired from the data storage unit 250, it is not necessary to receive these data from the user terminal 100 when generating reinforcement body layout plan data. Also, for example, if the server device 200 acquires and stores the installation condition data in advance in the data storage unit 250 and can acquire the installation condition data from the data storage unit 250, it is not necessary to receive the installation condition data from the user terminal 100 when generating reinforcement body layout plan data.

[0099] In the present embodiment, when supporting construction work estimates, the server device 200 receives reinforcement element layout plan data and construction cost data each time estimate data is generated. However, this is not limited to this. For example, in the present embodiment, the server device 200 stores the reinforcement element layout plan data in the data storage unit 250 when supporting the creation of a reinforcement element layout plan. The reinforcement element layout plan data can be acquired from the data storage unit 250. Therefore, when generating estimate data, the server device 200 does not need to receive the reinforcement element layout plan data from the user terminal 100. Furthermore, for example, if the server device 200 acquires construction cost data in advance and stores it in the data storage unit 250, and the construction cost data can be acquired from the data storage unit 250, the server device 200 does not need to receive the construction cost data from the user terminal 100 when generating estimate data.

[0100] In the present embodiment, when the server device 200 supports the work of guiding a construction machine to a pile core position and the work of creating a construction report, the server device 200 receives the reinforcement element layout plan data and the foundation position data each time the server device 200 generates the reinforcement element position data and the guidance order data. However, this is not limited to this. For example, in the present embodiment, the server device 200 stores the reinforcement element layout plan data in the data storage unit 250 when supporting the work of creating a reinforcement element layout plan. The reinforcement element layout plan data can be acquired from the data storage unit 250. Therefore, the server device 200 does not need to receive the reinforcement element layout plan data from the user terminal 100 when generating the reinforcement element position data and the guidance order data. Furthermore, for example, if the server device 200 acquires and stores foundation position data in advance in the data storage unit 250 and the foundation position data can be acquired from the data storage unit 250, the server device 200 does not need to receive the construction cost data from the user terminal 100 when generating the reinforcement element position data and the guidance order data.

[0101] 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, perform the central processing. For example, the programs for executing the above operations may be stored and distributed on a recording medium readable by the user terminal 100, server device 200, and construction management terminal 300, such as a flash memory, and the user terminal 100, server device 200, and construction management terminal 300 may be configured to execute the above processing by installing each program. Alternatively, each program may be stored in a storage device possessed by 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 download each program to configure the user terminal 100, server device 200, and construction management terminal 300.

[0102] In addition, if the functions of the user terminal 100, server device 200, and construction management terminal 300 are realized by sharing the functions of the OS and application programs, or by collaboration between the OS and application programs, only the application program portion may be stored on a recording medium or storage device.

[0103] The program may also be superimposed on a carrier wave and provided via a communication network.
