2. Description of the Related Art Underground, power pipes, gas pipes, water and sewage,
Various pipes and cables such as CATV cables and telephone cables are buried like a mesh. In particular, in the case of gas pipelines, the necessity of construction such as improvement of old gas pipelines or new construction for disaster countermeasures has increased since the Hyogoken-Nanbu Earthquake. The design work involved in burying gas pipes can be broadly divided into two types: "construction work" design and "other work" design. The construction work design is a design work when newly establishing gas pipelines in newly developed areas such as residential land development, and the other work design is to construct other underground objects such as water and sewage, electricity and telephone. This is a design work in which gas pipes are temporarily relocated when they are rebuilt and returned after the construction is completed.

Also, there are many cases where drawings are created separately,
Many different drawings need to be created for the same site. Accordingly, there is an urgent need to develop an effective design management system in response to increasing demands for construction such as repair, replacement, and relocation of aging gas pipelines and construction of new gas pipelines.

[0004]

SUMMARY OF THE INVENTION In view of such circumstances, the present invention aims at planning and designing gas pipelines, constructing gas pipelines, constructing gas pipelines from civil engineering / surveying and drawing input, and furthermore, designing the buried gas pipelines. The main purpose is to link a series of data processing processes up to the management in total, and to make work related to gas pipe burial design more efficient and labor-saving.

[Effect of the Invention] In the gas pipeline burying work support system according to one aspect of the present invention, burying of a gas pipeline is planned to support design-related work accompanying the laying work of a gas pipe. Based on the current state map data representing the topography of the site and the position data of the existing buried object, gas pipeline planning data representing the specifications of the buried route of the gas pipe and the specifications of the gas pipe to be used are generated, and the generated gas pipeline planning data is generated. Based on the plan, a plan plan, a plan sectional view, a supply pipe diagram, and an excavation sectional view, as well as a pipe quantity summary table, a supply pipe summary table, and an excavation area summary table are prepared.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. The following embodiment is merely an example, and various modifications can be made without departing from the spirit of the present invention.

[System Configuration] In the case of constructing a gas pipeline underground, as shown in FIG. 1, a survey stage (current survey, survey of buried objects) ST1 and a design stage (route selection, plane / longitudinal section, etc.) Road facility design, quantity calculation and totalization) ST

And maintenance).

In the investigation stage ST1, a survey is conducted at a site where the gas pipeline is to be buried, and the current topography (the shape of the road and the position of the building, etc.) is digitally measured. By investigating other types of buried objects,
Grasp the current topography and acquire the current data. In the next design stage ST2, a safe laying route of the gas pipeline is planned with due consideration of the current situation that has been grasped, design data such as plan floor plan and plan sectional view are created, and various calculation data are created. I do. After the design and quantity calculation, enter the construction stage ST4,
The gas pipeline is constructed according to the construction drawing created based on the design results. After the completion stage ST5, the management stage S

The main points of the gas pipeline burial work support system according to the present invention will be described with reference to FIG. In the investigation stage ST1, when the current state map data (a) representing the topography of the site where the gas pipeline is to be buried and the position data (b) of the existing buried object are acquired, the design stage S
At T2, gas pipeline planning data indicating the specifications of the buried route of the gas pipes and the gas pipes to be used is generated based on the current state map data and the existing buried object data (c), and based on the gas pipeline planning data. As a result, a plan drawing and various types of totalization tables are created (d). At the completion stage ST5 after the application stage ST and the construction stage ST4, these drawings or tallying tables are modified according to the result of the gas pipeline burial construction (h), and a completion drawing and a completion summation table are created (k ). Then, in the final management stage ST6, the completed drawing is further prepared into gas pipeline facility data suitable for subsequent management (m), and the gas pipeline facility data can be linked with the GIS system. It is stored in the gas pipeline equipment database and is provided for management (n).

FIG. 2 is a system block diagram showing the overall hardware configuration of the gas pipeline burying work support system according to one embodiment of the present invention. In this example, a personal computer (PC) is used as a host computer 1 that mainly performs a gas pipeline embedding operation in the system, and a CPU (central processing unit) 2, a system memory 3,
An external storage device 4, an input operation device 5 having operators such as a keyboard and a mouse, and a display device 6 such as a display;
These devices 2 to 6 are connected to each other via a bus 7.

The CPU 2, which controls the entire system, performs various controls in accordance with a predetermined program, and particularly centrally performs processing for the gas pipeline burial operation according to the present invention. Further, the system memory 3 includes a ROM (read-only memory) storing basic programs, programs relating to the gas pipeline burial operation and fixed data / parameters, and a RAM (random access memory) temporarily storing various data and the like.

Further, the external storage device 4 comprises a storage device using a storage medium such as a CD-ROM / FDD (floppy disk) / MO (magneto-optical) disk in addition to a hard disk drive (HDD). Stores programs and various data / parameters related to the underground work.
The external storage device 4 also has a data filing function for various databases and libraries, and can construct various databases and libraries for supporting sewerage installation design.

The input operation device 5 includes a display 6
By operating a predetermined key of the keyboard or instructing an operation button on the display 6 with a mouse or the like while visually recognizing various screens displayed on the screen, various processes for a gas pipeline burial operation can be performed. .

A bus 7 has an interface 8 for acquiring actual terrain data (three-dimensional coordinates), an actual measurement terrain data input device such as a computer 9 for the site, and a digitizer system 10 and a scanner system 11. A drawing data input device and a paper document output device such as a printer (for example, a color laser printer) 12 and a plotter (for example, a color inkjet plotter) 13 are connected.

In order to grasp the current situation of a site where a gas pipeline is to be newly buried, map data and attribute data already obtained by a GIS (Geographic Information System) which can be used by a design builder are used for the periphery of the site. It is often used, but since the present situation changes moment by moment, it is preferable to obtain the latest present plan view data digitally by observing the present situation using the on-site computer 9 etc. for the burial site and its vicinity. . The on-site computer 9 is, for example, a portable personal computer using apparatus called an “electronic flat panel”, and includes a total station (TS) 14 and a GPS (Global Positi).
A digital surveying device such as an oning system (global positioning system) device 15 is communicably connected via wireless devices 16, 17, 18 and 19, and an automatic contour line generating function is provided by application software.

The total station (TS) 14 is an external business machine that is installed on a tripod at the surveying site and used.
The angle and distance are obtained from the time when the light emitted from the illuminator is applied to the reflection mirror at the measurement point and returned, and the three-dimensional position coordinates are digitally measured. In the latest TS model, there is a non-prism type that does not require a prism. In addition, the GPS 15
This is a digital geodetic device based on the PS system. Due to the remarkable progress of recent technology, it has been downsized, the measurement operation is easy, the equipment is very simple, and the digital three-dimensional position is extremely accurate in a short time. Since coordinate data can be obtained, it is used when high-precision surveying is required because there is no high obstacle (curtain) such as a high-rise building around the surveying point in GPS surveying.

The digital survey data from the TS 14 or the GPS 15 is transferred to the site computer 9 by radio (or transmission line), and the program determines three-dimensional coordinates of each survey point (generally several hundred to 1,000 points).
Contour data is automatically generated. At the same time as the measurement,
By repeating the operation of inputting the attributes of points such as telephone poles and sidewalk edges, the on-site computer 9 can also generate current state map data (three-dimensional coordinates) on the screen.

On the other hand, in order to grasp the underground buried object already buried at the site, the GIS which can be used by the design builder is used, or by conducting a desk survey or a test excavation survey, the underground buried object is checked. Get current status data. In the case of a desk survey, a drawing reader such as the digitizer system 10 or the scanner system 11 can be used. The digitizer system 10 is a "digital tracer"
This is a method of reading drawing data of a paper drawing into the host computer 1 by tracing the drawing with a remouse, and reading only necessary objects. Therefore, only a part of the equipment drawing is read. It is suitable for the case, and the attribute is input simultaneously with the reading of the object.

The scanner system 11 is also an input device for taking a paper drawing into the computer 1. Since the scanner system 11 reads everything described in the drawings, it is suitable for reading accurate equipment drawings based on actual measurements, such as equipment drawings of a power company. When the scanner system 11 is used, a procedure is adopted in which all the drawings are once read and then attributes are given to only necessary parts. Therefore, which one of the digitizer system 10 and the scanner system 11 is used depends on the function and purpose.

The host computer 1 uses the input data from the input devices 9 to 11 and operates the input operation device 5 with the display assistance of the display 6 to thereby operate the respective stages ST1 to ST6 of FIG. Performs various processes for the tasks shown in. The product data obtained as a result of various processes by the host computer 1 is stored in the printer 1
2 and a plotter 13 are output as drawings and tables.

FIG. 3 is a functional block diagram schematically showing functions of the gas pipeline burying work support system according to one embodiment of the present invention. In the investigation stage ST1, the host computer 1 mainly uses the on-site computer (electronic flat panel) 9 to obtain the current state observation data, as shown in the functional block A of FIG. To obtain the latest digital plan data. That is, it receives digital survey data of each measurement position sent from the surveying devices 14 and 15 via the on-site computer 9 (or directly), determines three-dimensional coordinates of all survey points, and automatically generates contour line data. The current plane data is generated through an attribute input operation. When the current state map data (three-dimensional coordinates) generated by the on-site computer 9 is received, this data can be output as it is as the current state plane data.

Next, as shown in the functional block B, the host computer 1 traces the already buried underground objects from the existing drawings by using the drawing readers 10 and 11 and checks the buried facilities. Type and its position
Obtain data on the existing underground buried objects including information such as depth. The acquired existing underground object data is additionally input to the existing plane data, and the figure is edited using the input operation device 5 with the assistance of the screen display on the display 6 to correct the underground object data. Then, it is made to correspond to the current plane data accurately.

Subsequently, in the design stage ST2, the host computer 1, as shown in the functional block C, executes the gas pipeline filling design (the gas pipeline filling design according to the present invention requires only a new gas pipeline installation). Not include operations such as relocation and removal). In other words, in consideration of the current plane data generated by the on-site computer 9 or the function block A and the relationship with the existing underground buried object obtained by the function block B, the burial route is selected / determined to create the plan data. I do. For example, plan plane data, plan section data, and the like are created by inputting the attributes (for example, setting of pipe types) and positions of the underground gas pipes and meters.

Further, in the design stage ST2, as shown in a functional block D, various plan drawings are created from these plan data, and various quantities are totalized to obtain a pipe number total table, an excavated area total table, and the like. Created. These charts can be output on paper from the printer 12 or the plotter 13 as required, as indicated by the broken lines (the meaning of the broken lines is the same for the following functional blocks E to N). When the color inkjet plotter 13 is used, the final result drawing can be output in color at the maximum size. Then, various data obtained in the design stage ST2 is stored in the external storage device 4 provided in the host computer 1. When the gas pipes are laid by the propulsion method, a temporary structure diagram such as a temporary shaft drawing for the propulsion method using steel sheet piles, liner plates, and horizontal pile sheet piles is also created.

After completing the design stage ST2 after performing such design and quantity calculation, before the construction stage ST4 of the underground gas pipeline based on the design result, the license application operation stage ST3 indicated by the functional blocks E and F is performed. Entering and automatically obtaining documents from the planning data, such as a "Road Occupation Permit Application Form" and "Road Use Permit Application Form" to be submitted to the competent management / supervisory authority in order to obtain permission to bury the gas pipeline. . That is, in the functional block E, in order to occupy the road when burying the gas pipeline, the manager of the road with the underground buried gas pipeline is used.
Create a road occupancy permit application to be submitted to an organization [national or municipal (local office), etc.]. In the function block F, a road use permit application to be submitted to a road supervising agency (prefectural police station) to use the road and an attached document such as a traffic countermeasure map are prepared. Here, the plan data obtained in the function block D can be used as it is for creating the attached document.

When the permission application is passed, the operation proceeds to the construction stage ST4. Based on the plan data and the change instruction for the application, the computer 1 performs the construction according to the gas pipeline to be finally constructed as shown in a functional block G. Create a diagram. Based on this construction drawing, the burial work of the gas pipeline is performed and the completion stage ST5 is entered. When the burial work passes the inspection and is completed, as shown in the functional block K, the computer 1 The completed contents will be reflected in the construction drawings to create a completed drawing, and the completion cost will be estimated. This completed drawing is
Further, as shown in a functional block M, a gas pipeline facility diagram suitable for subsequent management is prepared, and a gas pipeline facility database (document cabinet) in the external storage device 4 is prepared.
And used for subsequent management. Then, in the management stage ST6, the computer 1 links the gas pipeline equipment diagram data stored in the gas pipeline equipment database with the GIS system and the drawing management system as shown in the functional block N, and interlocks with these systems. By doing so, the life cycle of various drawings and forms related to the gas pipeline burial work and the like is supported.

[Example of Processing Flow] FIGS. 4 and 5 are flowcharts showing the overall processing flow of the gas pipeline burying work support system according to one embodiment of the present invention. In step S1, when the current topography is digitally surveyed by the surveying devices 14 and 15, the survey result is sent to the host computer 1 via the on-site computer 9 or the like, and digital survey data (D1) representing the current topography is obtained. Can be In the next step S2, the current state map data (D2) is obtained based on the digital survey data (D1), and the current state map data (D2) is stored in the topographical database of the external storage device 4 provided in the host computer 1. DB1
(FIG. 7)].

Next, in step S3, data of an existing underground object of another kind (D3) is created. For this purpose, for example, an equipment ledger diagram of a company managing the existing underground buried object at the burial site is used, and if there is GIS data, it is used. Power pipes,
There are telephone pipes, water pipes, sewer pipes, and other buried objects,
It also includes gas pipes that are already buried.

Here, a method of reflecting the existing telephone equipment by the digitizer system 10 will be described. In this method, a telephone equipment drawing is set in the digitizer system 10, and first, an operation of matching the positional relationship between the current drawing generated by the host computer 1 and the telephone equipment drawing set in the digitizer system 10 is performed. That is, using the mouse (5), two points of the current state drawing and two points of the telephone equipment drawing [for example, a manhole, a corner of an intersection, etc.] are matched on the screen of the display 6 on a computer, It is assumed that both drawings are superimposed. In this superimposition work, the function to automatically change the scale is used,
Superposition can be performed even on drawings having different scales.

Subsequently, the object to be reflected in the telephone equipment drawing set in the digitizer system 10, that is,
Click on the telephone line with the mouse. Normally, the telephone pipeline is in a state only appearing on the screen as a picture, so the input screen is opened and attributes (for example,
Pipe material ("vinyl pipe" etc.) and pipe diameter ("100mm"
), Earth covering (“0.5 m to 1.0 m” etc.)]. Through this repetitive editing operation, telephone pipe current state data is obtained, and the telephone line is superimposed on the current state drawing to create a drawing in which the burial route of the telephone pipe is entered.

Next, a method of reflecting the survey result of a buried object by the scanner system 11 will be introduced. First, when the water supply equipment drawing obtained from the waterworks bureau is read by the scanner 11, the status of reading by the scanner is displayed on the screen of the display 6. When the reading of the drawing is completed, the read water supply equipment drawing is subjected to necessary processing such as drawing cleaning and drawing distortion correction, and the same two points are compared with the existing drawing already created on the computer. Overlay using the automatic scale change function.

When the two drawings overlap, an input screen is next opened, and the user clicks on the water pipe to be given an attribute, and the attribute (for example, pipe material ("steel pipe", etc.) or pipe) is added to the water pipe. Diameter (“200 mm” etc.), earth covering (“1.2 m to 1.5
m "))]. The water supply status data (D3) is obtained by this repetitive editing operation, and the data of the water supply equipment diagram is superimposed on the current status diagram to create a drawing in which the buried route of the water supply is entered. be able to.

Power pipes, sewers, and other buried objects are also superimposed with the same existing drawings,
Existing underground buried object status data (D3) can be acquired. These existing underground buried object data (D3)
If the data is raster data, it is vectorized by a vector conversion engine as necessary, and the data is divided into layers for each existing underground buried object status data, and the form of raster data or vector data is stored in the buried object database (DB2) of the external storage device 4. Can be stored. Then, step S4
In, the data on the state of all buried objects is
2) By reflecting the data on the existing buried object reflection data (D
4) is created. At the same time, current cross section data (D5) and current cross section data (D6) are created, and these data are also stored in the buried object database (DB2).

The design stage is entered from the following step S5. First, in step S5, the buried route is examined in consideration of the relationship with the existing underground buried object on the current plan (D3).
In step S6, the route for burying the gas pipeline is entered in the current state plan view (D3), and the burying route is determined. Gas is supplied to each customer through a supply pipe from a branch pipe connected to the main pipe, but the buried route is usually a main pipe, a branch pipe,
Decide in order of supply pipe. This includes display 6
On the screen of (3), call up the current plan (D3) or the reflection map of the existing buried object (D4) in which the reflection of the buried object is completed, and fill in the planned route to bury the pipeline on this screen using the mouse. Go. At this time, since the pipe line is simply drawn on the screen as a data line (skeleton), the attribute [for example, pipe type or pipe diameter [“80A” (= outer diameter 89 mm)
, Etc.), depth (such as “2.00 m”), change point, etc.]. By repeating this operation, the route and various specifications of the newly designed gas pipeline to be buried are determined and stored in the pipe type / diameter database (DB3) of the external storage device 4 as gas pipeline planning data (D9). I do.

In step S6, along with the determination of the embedded design route, construction section work data (D8) for the construction work of the gas pipeline is created for each of the previously planned construction sections.
In the next step S7, the gas pipeline planning data (D
Various plan drawing data is created based on 7), and in subsequent step S8, various quantity total data is created. The plan drawing data includes, for example, a plan plan view (D9), a supply pipe diagram (D10) for representing in detail a supply pipe connected to a branch pipe laid along the road at an angle of 90 °, and a plane to be excavated. A digging plan view (D11) representing (width and length), a planned sectional view (D12) at a predetermined location, a digging sectional view (D13) representing a section (width and depth) to be excavated at a predetermined location, and the like. Plan floor plan data (D9), supply pipe map data (D10) and excavation plan view data (D1
1) are stored in the pipe type / pipe diameter database (DB3), the supply pipe database (DB4), and the excavated area database (DB5) of the external storage device 4, respectively. Also,
The quantity count data includes a count quantity table (D1
4), a supply pipe total table (D15), a work type excavated area total table (D16), and the like.

Subsequently, the process proceeds to steps S9 to S12 (FIG. 5) to perform a task for applying for permission for private use and use of the road. First, in step S9, data necessary for applying for a road occupation permit is extracted from the current state map data and the plan data and edited, and a road occupation permit application (D17) and a number table attached thereto are created. I do. The written documents are submitted to the road manager (national or local government agency). As a result of the check by the road manager in step S10, if each document related to the road occupation permission application is incomplete (NG), the road manager issues an "application content change instruction" and performs the operation of step S9 again.

If the application passes the road occupancy permission application check in step S10 (OK), the process proceeds to step S11.
In, the data necessary to apply for a road use permit is extracted from the current state map data and design data and edited, and the road use permit application (D18) and the construction time (period) attached to this Create documents such as a list of effective road widths and traffic control maps. These documents are submitted to the road supervisor (the responsible police station), and again in step S
At 12, the road supervisor checks. Here, if the documents related to the road permission application are incomplete (NG), the road supervisor issues an "application content change instruction" and the work of step S11 is performed again.

In order to prepare documents (application form and list, etc.) necessary for such an application for road occupation and use permission, a form according to a format request from a road manager or a road supervisor of a submission destination must be prepared in advance. The pattern is stored in the format pattern library, and graphic data representing guardman, barricade, construction vehicle, etc. is stored in the graphic library.
While reading out the format pattern in accordance with the type instruction of document creation, necessary data is extracted from gas pipeline planning data obtained at the design stage. Then, by combining the extracted data with the read format pattern, an application form and a list can be created. In addition, the floor plan attached to the application (transportation plan, etc.) is also cut out from the plan floor plan, necessary figures are taken out from the figure library, combined with this drawing, and guardmen etc. are arranged freely. be able to. As for a specific method of preparing documents for such a road occupation permission application or a road use permission application, the present inventor has already proposed in Japanese Patent Application No. 2000-8675. I want to be.

When there is an "application content change instruction" from the road manager or the road supervisor in steps S10 and S12, if there is a defect in the designed gas pipeline filling design itself, the flow returns to step S6. Steps S6 to S9,
Steps S6 to S11 are repeated. Then, step S1
After passing the check of the road use permission application in 2 (OK) and completing the submission of each application document, the construction stage (S13)
to go into.

In step S13, steps S10 and S12
A construction drawing consisting of a floor plan and a cross-section drawing that reflects the results of the checks made in the above is created, and the gas pipeline burial construction work is carried out on site based on these construction drawings. This construction work is performed while changing the contents of the construction drawing data in accordance with the progress of the work process and the confirmation of the inconvenient location. When the burial work is completed and the inspection is passed, in step S14, based on the construction content change data obtained in the construction stage, a final drawing of the gas pipeline whose burial is completed is created. After completion, the process proceeds to step S15, and the gas pipeline completion drawing is re-prepared to a gas piping facility drawing suitable for management.

In step S16, this gas pipeline facility diagram is linked with a GIS system and a drawing management system to construct a comprehensive gas pipeline diagram management system, and the subsequent maintenance of the buried gas pipeline facility is performed.・ Inspection and maintenance. For example, by linking a gas pipeline facility drawing with a drawing management system, drawing management is performed for each construction subject, and support for the life cycle of various drawings and forms and integrated management of information are realized. In addition, by linking with the GIS system, information search and management can be realized on a map basis, and can be used for various requests such as construction of other buried objects.

That is, a gas pipeline drawing management system in which a gas pipeline equipment database storing a large amount of gas pipeline equipment diagrams and a drawing management system are linked, searches, browses, outputs, and outputs gas pipelines when necessary. It can be used as an electronic cabinet that can perform management tasks such as correction. In the gas pipeline drawing management system, construction CA
In order to support the digitization of data promoted by LS / EC, not only drawings but also data such as application forms and calculation documents, digital camera image data, scanning image data, etc. can be stored collectively. Become.

For example, a thumbnail display drawing is reduced on the display 6 so that a target gas pipeline drawing can be quickly checked. When this drawing is double-clicked with the operation unit 5, a corresponding application is started up. Can be modified. In addition, a high-speed search that considers human judgment can be performed, and searching can be performed using eyes on a large screen, as if turning a page of a photo book or a catalog. By using this information card, it is possible to perform a narrowing search for searching for a necessary document from a huge amount of data.

Further, the gas pipeline facility database is linked with the GIS system together with the terrain database (DB1) which is updated successively and the buried object database (DB2) in which other buried object data is stored, and the GIS system is used. Build a gas pipeline ledger management system. This GIS-based gas pipeline ledger management system centrally manages facility data, equipment drawings, and forms obtained and created during the gas pipeline design and construction stages, thereby supporting the maintenance and management of gas pipeline facilities. In addition, it is possible to efficiently inquire various information and output drawings and forms based on the map.
