DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a design support system for burying an underground line (pipe).

[0002]

2. Description of the Related Art As a series of business steps involved in the construction work of an underground line, surveying of an area to be constructed, preparation of a current state map based on survey data obtained by this survey, and burial already in this area. Create a reflection map by adding the equipment map of the buried object to this existing map, and based on this reflection map, the underground pipeline,
Create a laying route diagram with the laying route of the manhole, read the radius of curvature of the laying route from this laying route diagram,
The process of calculating the equivalent pipe length, calculating the cable tension, and determining whether the tension is within the allowable limit. Based on the cable tension calculation result and the pipe installation data to be laid, Estimation work to calculate the cost of construction and construction costs, road occupation permission application to obtain construction permission and road use permission application work, changes to these applications, requests from the road manager or police, Creation of a construction drawing with added information, creation of a completed drawing with the construction drawing modified based on the construction result after completion of construction, creation of equipment drawing to trace the completed drawing, and equipment drawing to keep this equipment drawing in cabinet etc. There is a series of business processes such as management.

Conventionally, in surveying, first, a survey using a hand flat plate has been performed, and a method has been adopted in which a survey is performed using a flat plate measuring instrument and a tape measure, and a drawing is directly drawn on a drawing on site. In the preparation of the present situation map, the handwriting is usually handwritten at a scale of 1/500 based on the result of the flat plate survey. When creating the reflection map, the route of the buried object that has already been buried is manually added to the current state map based on the equipment ledger drawings of other buried companies. Regarding the preparation of the laying route map, it is manually added based on the reflection map and the underground line construction outline. Then, in the cable tension calculation, the radius of curvature is actually read from the laying route diagram to calculate the equivalent pipe length, and it is confirmed whether the cable pulling tension is within the allowable limit. Here, if the cable pull-in tension is not within the allowable limit, the laying route diagram is created again, the cable tension is calculated based on the corrected laying route diagram, and the cable pull-in tension is within the allowable limit. After confirming this, the laying route map is determined. After the laying route diagram is determined in this way, the multiplication work is performed independently based on the laying route diagram (hereinafter, referred to as a “design drawing”).
In preparing documents for a road occupation permit application to be submitted to the road manager, the amount of private property (pipelines and manholes) is read from the blueprints in order to calculate the occupancy fee during construction, Summarize in a table and submit the application to the administrator with the contents attached. In addition, as a document to be submitted to the police station for permission to use the road, a traffic countermeasure diagram for construction, construction time, and a list of effective road widths will be created. The creation of this list is performed manually while checking the design drawings and integrated data. After the above application for permission, if there is a request for a change in the documents submitted by the manager or the police station, if there are any changes related to the blueprint, they will be corrected by hand. The construction drawing is completed through such a process, and actual construction is performed based on the construction drawing. After the completion of the construction, if there is a change at the time of construction, the completed drawing will be completed by adding the contents to the construction drawing. Further, by tracing this completed drawing, a facility drawing is created. In such business operations, the creation of drawings is performed exclusively by hand.

[0004]

In the above-mentioned prior art, each process operation is performed independently.
Throughout, there are many issues to be solved from the viewpoint of work efficiency and drawing quality. First, in the surveying process, since survey data is directly written on a sheet, the scale of the drawing cannot be changed. As a problem in the preparation of the current state map, there is a case where it is difficult to draw a detailed portion only with the flat plate survey data. Further, when a drawing with a different scale is required, it is necessary to scale up the current drawing once prepared and to prepare the drawing again, which requires time and effort. Although it can be cited as a defect common to handwritten drawings, there is also a problem that the drawing quality varies depending on the skill of the creator. The problem in creating the reflection diagram is that the efficiency and accuracy are poor because the equipment ledger drawing is added by hand. In the preparation of the laying route diagram, when the laying route of the pipeline or the manhole is determined, it is necessary to copy the route. Next, as a problem in the cable tension calculation, a series of cable tension calculations are manually calculated based on the individually read radius of curvature from the installation route diagram, but it takes much time to read each radius of curvature. Cost. Further, depending on the result of the calculation, it is necessary to change the laying route diagram. In this case, after manually correcting the laying route diagram, changing the data for calculating the cable tension based on the corrected laying route diagram. A series of steps, such as confirming that the cable tension calculation result is within an allowable limit, or a lot of time and effort required for repeating the series of steps, is a major issue. In addition, in the integration process, since there is no coordination of data with other processes, data in the previous processes cannot be effectively used, and there is much waste. In addition, the number of pipelines and manholes by specification required for preparing a staff table for road occupancy permission applications required work to read from the design drawings, which took a long time. In the application for permission to use the road, it is particularly necessary to submit the traffic countermeasures map for each construction site and in chronological order. Therefore, it is necessary to create dozens of traffic countermeasure maps, and this creation takes a long time. Regarding the construction drawings and the completed drawings, the drawings are corrected by hand, and it takes a long time as described above. In addition, regarding equipment drawing,
Outsourcing of construction drawings to contractors is time consuming and expensive. Until the completed equipment drawing is filed as a ledger original drawing, 15
It takes up to 30 days, and in some cases, inquiries may be required in connection with other construction work, or there may be cases where it is not possible to respond in real time to various requests such as maintenance. Was imminent.

[0005] The present invention has been made in view of these points, and aims to improve the efficiency of business and to correct and correct drawings.
To provide an underground line support system that can make changes in real time, create high-quality drawings, and respond sufficiently in real time to the increase in design support work accompanying an increase in orders. With the goal.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a system flowchart showing an embodiment of the present invention. In the system according to the present embodiment, first, in order to create a current state map of the ground in a target area set as a site where an underground wire is buried, surveying of buildings, roads, trees, etc. constructed in that area is performed. By digital surveying. A digital flat plate and a light wave range finder are used for this survey, and position coordinate data and height data of a building or the like are obtained by three-dimensional observation (STEP.1).
These digital survey data are stored as CAD data in the storage unit of the computer, and a current state diagram as shown in FIG. 4 is created by the CAD (STEP. 2). Although not shown in FIG. 4, the present status map has the same notation as a normal map specification. Next, it takes in the equipment ledger drawings and data related to each of the companies that have already buried, and creates a buried object reflection diagram that reflects these data in the current status map. I do. As the equipment ledger diagram, for example, the NTT shown in FIG.
There are a ledger diagram, a sewage ledger diagram shown in FIG. 3 (b), a water ledger diagram shown in FIG. 3 (c), and a gas pipeline ledger diagram (not shown). These data are fetched as drawing data in a state where the scale and the reference point are aligned by a scanner or a data tracer, and are added to the current state diagram. In addition, individual survey data on buried objects will be reflected on the existing map (STEP.3).

[0010] In the buried object reflection diagram created in this way, the laying route of the pipeline or the human hole is entered by CAD. Further, the pipe material, the pipe diameter, the number of holes, the earth covering, and the like are input as the attributes related to the pipeline and the manhole, and a plan view of the laying route diagram as shown in FIG. 7 reflecting these data is created. You. In the laying route drawing, in addition to this plan view, a longitudinal section view and a cross section view are created.

The cable tension to be buried must be laid with a tension within a range not deteriorating its performance. When selecting a laying route or a manhole position, the cable tension calculation in the designed laying route is actually performed. Then, it is determined whether the calculation result (A) is within the allowable limit. If the calculated result (A) exceeds the allowable limit, the installation route is corrected again. Regarding the corrected installation route, the cable tension calculation and the calculation result are determined, and the calculation result (A)
Is determined to be within the allowable limit, the designed laying route diagram is determined as a design diagram. In practice, shortening the span length of the installation route results in an uneconomical design. Therefore, it is preferable to design so as to be close to an allowable limit. (STEP.4)

In the cable tension calculating method according to the present embodiment, a route shape of a pipeline is read from a laying route diagram, a radius of curvature is automatically calculated, and an equivalent horizontal pipeline length L is calculated.
(M) is automatically calculated. Using the equivalent horizontal pipeline length L, the input coefficient of friction (μ) and the weight per unit length W (Kg / m) of the cable, the cable pulling tension T (Kg) is calculated by the following equation (1). Is done.

T = μ · W · L ‥‥ (1) In this tension calculation, input data as shown in FIG. 8 is input for each pipe buried between the human holes. Done. For example, for a CVT cable, the allowable tension is 6 kg /
mm ² . In the cable tension calculation, the curvature radius is automatically calculated from the installation route drawing as described above, so that the tension calculation can be easily performed repeatedly.

Next, the data (pipe type, pipe length, number of holes, earth covering) which can be read from the laying route diagram and automatically transferred, and the pavement thickness and restoration work type which have been input in advance. Based on the construction data of the contractor and the man-hours calculated automatically, and additional construction data such as iron pipe bending and protection of buried objects, estimate the materials and construction costs of the construction and calculate the underground wiring construction design document Various specifications are prepared (STEP.5).

Next, a road occupation permission application and a road use permission application are carried out in order to receive a construction permission. First, in the road occupation permission application work, a road occupation permission application shall be submitted, and a number table prepared and attached. This number table is created automatically by reading the specification-specific quantities of pipes and manholes to be laid from the laying route diagram. In addition, in the road use permission application work, submit a road use permission application form and create a traffic countermeasure diagram, construction time and road effective width quoter list in construction. When creating the traffic countermeasure map, use the laid route map, and input information such as the effective road width guidance staff and road occupied sections as data for each elapsed time of construction. Take the form that reflects. In addition, the construction time and the list of effective road widths and the road use permission application cover are automatically created by using the data already entered when creating the traffic control map (STEP.
6).

The road occupation permission application is made to the road manager, and the road use permission application is made to the police station with the above documents. Thereafter, the road manager and the police station may request that the application be changed. In this case, the laying route diagram is corrected based on the changed contents. Thus, the design drawings permitted by the road manager and the police station are the construction drawings used for actual construction.
Plans, longitudinal sections, and cross sections are created as the construction drawings (STEP.7).

After that, construction is performed based on these construction drawings. If there is any change in the original construction drawings at the stage of completion of the construction, the data of the change of the construction contents should be added to the construction drawings. To create a completed drawing (facility drawing) 27. Plans, longitudinal sections, and cross-sections are created as this construction drawing (STEP.8).

The completed drawing (equipment drawing) 27 is managed as an equipment drawing, and it is possible to respond in real time to various requests such as a case where an inquiry is required in connection with another construction or a maintenance. Since drawing is performed using CAD, there is no need to trace the completed drawing to create the equipment drawing as in the past, and at this stage the completed drawing becomes the equipment drawing as it is, and the time required for equipment drawing management is the same as before. Efficient because it does not take many days as in.

The above embodiment has a hardware configuration as shown in FIG. As a digital surveying instrument, a digital flat plate and a light wave range finder are used, and surveyed survey data is stored as digital data in a storage section of CAD data. As digital data, inputting a drawing as a digital drawing by a scanner is adopted, and the inputting operation is facilitated. The digital data thus input is applied to each business process as CAD data together with construction data, cable data, pipeline data, and cable tension calculation data. By digitizing data and constructing a system using CAD, business processes are linked to each other, and business efficiency can be improved. Also, even if there are various changes and corrections, it is possible to easily respond in real time by using CAD. Further, the use of the CAD makes it possible to increase the efficiency of drawing creation work and create detailed parts of the drawing.
Until now, drawing by handwriting has been uneven in quality because it depends on the skill of the creator. However, the system according to the present embodiment eliminates these points and improves drawing quality.

[0020]

As described above, the underground railway support system of the present invention introduces digital surveying data by using digital surveying means, and the present situation drawing means is based on this digital surveying data. The CAD is used to convert the existing map into a digital drawing, and the buried object reflection diagram creation means creates a buried object reflection map by adding it to the existing map with the scale and reference point aligned by a scanner or digital tracer. The creation means and the completion drawing creation means are configured to create or modify each digital drawing by CAD based on the digital drawing of the above laying route map, and use the completion drawing created by the completion drawing creation means as an equipment drawing. At the same time, the cable tension calculating means automatically calculates the radius of curvature from the digital drawing of the laying route map, thereby The configuration is such that the horizontal pipeline length is calculated automatically, and the data necessary for each processing is transferred from the digital drawing of the laying route diagram to the integrating means and the permission application preparation means. Correction / change of drawings can be easily performed in real time via data, and high quality drawings can be created. Further, since the operation can be unified, the efficiency of the operation can be improved, and the cost can be reduced.
Furthermore, the present system can sufficiently respond in real time to an increase in design support work accompanying an increase in orders.
