For example, when there is an existing common groove in a part of the route 132 of the cable 131 to be laid, the region is set as the common groove, and the other regions are other methods such as a direct buried type and a piping type. Set by.

  In the present embodiment, such a laying design 130 is input from the terminal 20, but is not particularly limited thereto. For example, a laying design server that performs the laying design 130 is provided via the network 10. The laying design server 130 may be input from the laying design server.

  On the other hand, the database (DB) 200 includes an existing equipment database 210 that covers existing facilities of underground cables, a laying information database 220 that covers information and laws to be examined for laying underground cables, It includes at least a construction standard database 230 that covers the construction standards and laws of equipment, and in this embodiment, further includes a regional management center database 240 that covers comprehensive information on underground facilities. The database 200 is not limited to this, and may further include necessary information. Further, the database 200 is illustrated as being provided in the pipeline construction management server 100, but the database 200 is not limited to this, and all or part of the database 200 is connected via a network or the like, and the pipeline construction design means 110 is provided. Anything can be referred to.

  Here, the existing facility database 210 stores installation design related to existing underground electric lines, construction designs of various facilities, and the like. The pipe construction design means 110 refers to such an existing equipment database, and will be described in detail later. For example, piping such as whether a cable can be added to the existing route or equipment such as new piping is necessary. The construction design 140 can be performed in detail.

  In addition, the laying information database 220 covers information and laws that should be considered for laying underground cables, and various technical information such as terrain information, regional information, road law, river law, etc. Legal information. Specifically, for example, data on the ground such as landfills, data on roads such as road width and slope, data on facilities such as the position of road signs, the position of fire hydrants, utility poles, Examples include prohibited area data. The pipe construction design means 110 refers to such a laying information database 220, which will be described in detail later, but selects the method of foundation work depending on the soil, such as when there is a possibility of uneven settlement such as soft ground, The piping construction design 140 such as selection of the pipe type of the pipe depending on the distance to the sea or the railroad track can be performed in detail.

  Furthermore, the construction standard database 230 covers construction standards and laws related to the construction work of underground conduit lines. Specifically, in the construction standard database 230, pipe type selection data for selecting the pipe type based on the cable selected by the laying design 130 by the pipe construction design means 110, and a pipe line for selecting the number of pipe lines Number selection data, inner diameter selection data for selecting the inner diameter of the pipe, foundation construction selection data for selecting the method of foundation work depending on the soil, such as where there is a risk of uneven settlement on soft ground, pipes for selecting the pipe arrangement according to the number of holes Arrangement selection data, pipe arrangement change selection data for changing pipe arrangement when avoiding underground objects, bent pipe selection data for selecting horizontal length against height difference when using bent pipe, and pipe connection selection Pipe connection data, pipe pillow selection data for selecting the use of pipe pillows, buried pipe marking selection data for selecting markings for buried pipes, backfill data for selecting pipe backfilling, rise of power poles for pipes Such as a constant tubes rising selection data is stored.

  An example of selection data included in the construction standard database 230 is shown in FIGS. 3 is a table showing pipe type selection data, FIG. 4A is a table showing pipe number selection data, and FIG. 4B is a table showing pipe inner diameter selection data. As shown in FIG. 3, the pipe type selection data included in the construction standard database 230 is stored as a table so that the pipe type corresponding to the line type of the cable 131 selected in the laying design 130 can be selected. It is. Further, as shown in FIG. 4A, the pipe number selection data included in the construction standard database 230 is the type of pipe line determined by the route 132 selected by the laying design 130, the line type of the cable 131, and the like. Are stored as a table so that the number of pipes corresponding to the number can be selected. Further, as shown in FIG. 4B, the pipe inner diameter selection data included in the construction standard database 230 is a table so that the inner diameter of the pipe corresponding to the line type of the cable 131 selected in the laying design 130 can be selected. It has been accumulated.

  Note that the construction standards database 230 may store construction standards and laws related to other equipment construction of underground cable conduits. Here, as other installation work of other underground electric lines, various works such as manholes, hand holes, equipment, and ground lead-in lines can be cited.

  In addition, the regional management center database 240 covers comprehensive underground facility information. For example, other piping routes such as water and sewage and gas other than underground electric lines, the number of pipes, pipe diameter, Examples include the laying method and the location and structure of equipment and equipment such as manholes for water pipes. The regional management center database 240 may not be stored in the database 200 of the pipeline construction management system, and may be installed outside.

  While referring to such various data in the database 200, the pipe work design means 110 performs a pipe work design 140 based on the input laying design 130. Here, the construction design 140 designed by the pipeline construction design means 110 includes, as shown in FIG. 2, selection of pipes such as the pipe type 141, the number of pipes 142, the pipe inner diameter 143, and the pipe foundation work 144, Tube arrangement 145, arrangement change 146, which is a change in pipe arrangement, pipe connection 147, which is a method of connecting pipes, pipe indication 148, which is an indication of a buried pipe, pipe pillow 149 such as the interval between pipe pillows, Examples of the design include selection of detailed construction of piping such as backfill 150 and telephone pole rising construction 151.

  Specifically, the pipe type 141 of the pipe is determined by referring to the pipe type selection table shown in FIG. Designed to match the line type. That is, as described above, the construction standard database 230 stores the pipe type selection table for selecting the pipe type according to the line type of the cable 131 included in the laying design 130. The pipe type 141 is selected by referring to the pipe type selection table based on the laying design 130. For example, when the line type of the cable 131 of the laying design 130 is a high-low voltage underground distribution line, the pipe is selected from a reinforced plastic composite pipe, a C-type reinforced plastic composite pipe, an impact-resistant hard polyvinyl chloride pipe, and a galvanized lightweight steel pipe. Is done. At this time, the pipeline construction design means 110 refers to the laying information database 220 to determine whether there is a place where there is a possibility of salt water infiltrating the route 132 where the underground electric wire is laid, such as a landfill. When there is a ground or the like, a pipe other than the galvanized lightweight steel pipe is selected. Further, in FIG. 3, a plurality of tube types can be selected according to the line type of the cable 131, but for example, selection may be made with a priority given priority to cost.

  Further, the pipe number 142 is determined by referring to the pipe number selection table shown in FIG. 4A included in the construction standard database 230 described above by the pipe construction design means 110. Designed by the line type. That is, as described above, the construction standard database 230 stores a pipe number selection table for selecting the pipe number 142 according to the number of lines and the line type of the cable 131 included in the laying design 130. The pipe construction design means 110 selects the pipe number 142 by referring to the pipe number selection table based on the laying design 130. For example, when the line type of the cable 131 of the laying design 130 is a low-voltage trunk line, the number of pipes is one, but when the line type of the cable 131 is a supply line, the number of pipe lines is a sum of 1 + 1 (for backup). There will be two.

  Further, the pipe inner diameter 143 of the pipe is determined by referring to the pipe inner diameter selection table shown in FIG. Designed by seed. That is, as described above, the construction standard database 230 stores a pipe inner diameter selection table for selecting the pipe inner diameter according to the line type of the cable 131 included in the laying design 130. The pipe inner diameter 143 is selected by referring to the pipe inner diameter selection table based on the laying design 130. For example, when the line type of the cable 131 of the laying design 130 uses a special high-voltage line CVT100, the inner diameter of the pipe is selected to be 125 mm.

  As described above, the pipeline construction design means 110 comprehensively makes a judgment based on the laying design 130 while referring to the database 200, and outputs the detailed construction design 140 of the underground conduit.

  In addition, as a result of various studies, the pipeline construction design means 110 returns to the stage of redesigning the laying design 130 when the piping construction design 140 is difficult. Further, the redesigned laying design 130 is further examined, and a construction design 140 is created. That is, the pipeline construction design means 110 performs the construction design 140 with reference to the database 200 based on the laying design 130. However, when it is difficult to create the construction design 140 from various data stored in the database 200, That is, when the construction design 140 cannot be created, the cable 131, the route 132, and the laying method 133 are changed by returning to the stage where the laying design 130 is redesigned. The pipeline construction design means 110 redesigns the construction design 140 while referring to the database 200 based on the laying design 130 in which the selection of the cable 131, the route 132, and the laying method 133 is changed. Yes. As described above, the pipe work design means 110 refers to the database 200, and when the construction design 140 is difficult, the pipeline construction design means 110 returns to the stage of redesigning the laying design 130, and repeats the construction design 140 to supply power. The optimum piping construction design 140 based on the plan can be efficiently and accurately performed.

  When the construction design 140 is completed, there is a high possibility that this laying work will be executed. For example, the construction design 140 is registered in the existing equipment database 210. This is because the construction design 140 designed based on the next laying design 130 is used. Of course, a database dedicated to the planned facility may be created so that it can be referred to.

  In the present embodiment, the pipeline construction design means 110 receives verification data 160 that verifies the site where the builder constructs the pipe laying work based on the construction design 140, and the pipeline construction design means 110 receives the verification data 160. Based on the verification data 160 and the designed construction design 140, it is determined whether it is difficult to perform the piping laying construction. When it is determined that the laying work is difficult, the pipeline work design unit 110 refers to the verification data 160 and redesigns the work design 140.

  Here, the case where it is difficult to lay the piping is the result of the field verification actually performed based on the construction design 140. For example, the number of necessary pipelines is laid by other underground facilities. If it is not possible or the topography information in the laying information database 220 has been selected with a route along the normal road, the pipe type, etc. This is a case where the construction design 140 needs to be changed. In such a case, the verification data 160 is sent to the pipe work design means 110 via the terminal 20, so that the pipe work design means 110 determines whether the work design 140 needs to be changed and determines that it is necessary. In such a case, the construction design 140 is redesigned.

  Here, the operation of such a pipeline construction management system will be described in detail. FIG. 5 is a flowchart showing the operation of the pipeline construction management system.

  First, when the laying design 130 is designed based on the power supply plan in step S1, the pipeline construction design means 110 starts the construction design 140 referring to the database 200 based on the laying design 130 in step S2. Then, in step S3, the pipeline construction design means 110 determines whether the piping construction design 140 has been completed. If the construction design 140 has been completed (step S3; Yes), the construction by the pipeline construction design means 110 in step S4. When the design 140 is completed, the construction design 140 is output. In step S5, the pipeline construction design means 110 updates the existing equipment database 210 with the construction design 140. If the construction design cannot be performed in step S3 (step S3; No), the process returns to step S1 and the laying design 130 is redesigned.

  After that, in step S6, the pipeline construction design means 110 receives the verification data 160 obtained by performing on-site verification based on the construction design 140 so that the builder can actually perform the piping construction work, and the pipeline construction design means 110. If it is determined that the pipe laying work cannot be performed based on the verification data 160 and the work design 140 (step S6; No), the steps S2 to S5 are repeated to redesign the pipe work design 140. The existing equipment database 210 is updated with the new construction design 140. Further, when it is determined in step S6 that the pipe construction design means 110 has received the verification data 160, the pipe construction work can be performed based on the verification data 160 and the construction design 140 (step S6; Yes), in step S7, the piping is actually laid.

  In this step S6, the verification data 160 received by the pipeline construction design means 110 is used to reconstruct the piping construction design 140 with an unexpected obstacle while the construction work is being performed by the installer. It also includes data when it must be designed.

Further, the pipe work management server 100A includes work procedure presenting means 120 that extracts a necessary work procedure 170 related to the piping work design 140 from the work procedure database 250 and presents it to the terminal 20A carried by the installer. .

  In response to the request 180 from the terminal 20A, the work procedure presenting means 120 extracts a work procedure 170 suitable for the progress of the pipe laying work based on the work design 140 from the work procedure database 250 and transmits it to the terminal 20A. . Then, the builder can proceed with the piping laying work according to the work procedure 170 displayed on the screen of the terminal 20A. In this way, since the builder can perform the laying work while referring to the work procedure 170 based on the piping work design 140, the laying work of the pipe can be performed regardless of the difference in the knowledge and technical ability of the builder. It can be done efficiently and accurately. Further, the request 180 sent from the builder's terminal 20A includes the progress of the work, and the work procedure presenting means 120 sends the work procedure 170 to the terminal 20A in accordance with the work progress included in the request 180. It comes to present. For this reason, the pipeline construction management server 100A can always grasp the progress of the pipe laying work, and can allow the third party to confirm the progress of the work via the terminal 20. Thereby, management of laying work can be performed efficiently.

  In the present embodiment, the verification data 160 can be transmitted from the terminal 20A carried by the installer. For this reason, the construction design 140 can be redesigned even during the piping laying work, and the redesigned construction design 140 can be confirmed at the site where the builder is laying the work. In addition, the piping construction work can be performed efficiently and accurately.
