  For example, when the cable type designed by the laying design 130 is a multi-core (unshielded) cable, the cable construction design means 110 winds the cable when the diameter of the cable designed by the laying design 130 is Dmm. The drum diameter is designed to be 12 Dmm or more. Further, when designing the drum diameter, the cable construction design means 110 refers to the regional information in the laying information database 220 so as to consider whether the drum can be arranged near the manhole into which the cable is drawn. It has become.

  In addition, for example, the cable construction design unit 110 designs the drawing direction so that the cable is drawn from the one with the smaller drawing tension when the cable is drawn. This pull-in tension is designed so that the cable is pulled in from the higher side, for example, when there is a height difference in the pipes and caverns to be installed, and when there is a bent part in the middle of the pipes and caverns Designed to be pulled in from the side closer to the bend. As described above, the information such as the height difference and the bent portion referred to when the cable construction design means 110 designs the pull-in direction is the existing piping information in the existing equipment database 210, the terrain information in the laying information database 220, and the construction design database.

  For example, the cable construction design means 110 is designed so that the height from the floor to the lowest connection portion in the manhole is 380 mm when the line type of the cable designed by the laying design 130 is a high voltage cable. To do. Also, the support interval in the manhole of the high voltage cable is designed to be 500 mm. At this time, by referring to the manhole construction design stored in the construction design database 240, the width, depth, and depth of the manhole are obtained, and the height of the cable connection portion and the cable support interval are determined in accordance with the manhole structure. It can be designed as appropriate.

  Further, the grounding design of the cable includes, for example, a grounding design such as single-sided grounding or double-sided grounding of the cable by an induced voltage, and a design of a ground sharing method at a connection point between the overhead wire and the underground wire.

  For example, when the transformer is installed on the cable rising column, the cable construction design means 110 designs so that the second type installation work is performed independently. The presence or absence of the transformer at this time can be acquired by referring to the construction design database 240, the existing equipment database 210, or the like, for example.

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

  In addition, as a result of various studies, the cable work design unit 110 returns to the stage of reviewing other work designs stored in the database 200 when the cable work design 140 of the cable laying work is difficult. Then, the cable work design is created by examining the redesigned other work design.

  Here, the case where the cable work design 140 by the cable work design means 110 is difficult includes, for example, the case where the curvature radius of the pipe designed by the pipe work design is smaller than the allowable bending radius of the cable. In such a case, the cable work design means 110 examines the pipe work design suitable for the allowable bending radius of the cable and redesigns the pipe work design.

  As described above, the cable work design unit 110 performs the cable work design 140 while referring to the database 200 based on the laying design 130. However, it is difficult to create the cable work design 140 from various data stored in the database 200. In other words, that is, when the cable work design 140 cannot be created, it is returned to the stage where another work design is redesigned (reconsidered), so that the pipe work design, the manhole work design, the handhole work design, the equipment work It is designed to perform redesign such as design and underground service line construction design. Then, the cable work design means 110 redesigns the cable work design 140 based on the laying design 130 while referring to the database 200 including other redesigned work designs. As described above, the cable construction design unit 110 refers to the database 200, and when the cable construction design 140 is difficult, the cable construction design unit 110 returns to the stage of redesigning another construction design, and repeatedly performs the cable construction design 140. It is possible to efficiently and accurately perform the cable work design 140 of the optimal cable laying work based on the power supply plan.

Based on the verification data 160 and the designed cable work design 140, it is determined whether it is difficult to perform the cable laying work. The cable construction design means 110 redesigns the cable construction design 140 with reference to the verification data 160 when it is determined that the cable laying construction is difficult.

  Here, the case where it is difficult to carry out cable laying work means that, as a result of performing on-site verification based on the construction design 140, for example, the cable drawing work cannot be performed by other underground facilities. There are cases where the cable pull-in work cannot be performed due to the influence of the ground structure, etc., or when the grounding position of the manhole or handhole needs to be changed. In such a case, when the verification data 160 is sent to the cable construction design means 110 via the terminal 20, the cable construction design means 110 judges whether or not the cable construction design 140 needs to be changed. The company redesigns the cable work design and considers other work designs.

In step S <b> 3, the cable work design unit 110 starts designing the cable work design 140 of the cable laying work with reference to the database 200 based on the laying design 130. In step S4, the cable construction design means 110 determines whether or not the cable construction design 140 for cable laying construction has been completed. If the cable construction design 140 has been completed (step S4; Yes), the cable construction design means in step S5. When the cable work design 140 according to 110 is completed, the cable work design 140 is output. In step S6, the cable work design unit 110 updates the existing equipment database 210 with the cable work design 140. If the cable work design cannot be performed in step S4 (step S4; No), the process returns to step S2 and another work design is redesigned.

  After that, in step S7, the cable construction design means 110 receives the verification data 160 obtained by performing on-site verification based on the cable construction design 140 so that the builder can actually perform the cable laying work. If it is determined that the cable laying work cannot be performed based on the verification data 160 and the cable work design 140 (No at Step S7), Steps S3 to S6 are repeated to perform the cable work design 140 for the cable laying work. While redesigning, the existing equipment database is updated with the new cable construction design 140. If it is determined in step S7 that the cable construction design means 110 has received the verification data 160, but the cable laying construction can be performed based on the verification data 160 and the cable construction design 140 (step S7; Yes), cable laying work is actually performed in step S8.

  In this step S7, the verification data 160 received by the cable construction design means 110 is the cable construction design of the cable laying work with an unexpected obstacle while the builder is laying the cable. It also includes data when 140 has to be redesigned.
