DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a progress check system for plant construction work according to the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a conceptual diagram of a progress check system for plant construction work according to this embodiment.
In FIG. 1, reference numeral 10 is a local work plan support system for power plant construction and the like, and this system is a computer system that supports process plan formulation in power plant construction local work. The main function of the local construction plan support system 10 is to create a zone-specific process 14 for each construction zone of the power plant. Reference numeral 12 is a local construction progress confirmation system, which is a computer system for confirming the progress of the local construction.

  The actual construction process at the site is managed by using a process chart in the form of a local process chart 16 every three months or every three weeks as shown in FIGS. This on-site process table 16 is created using the process creation support system 18 based on the data of the section-specific process 14 for each construction section.

  For example, the construction section of the power plant is given a name for identifying the section as shown in FIG. In each section, for example, as a type of construction, if there is a piping construction, there are a number of constructions such as XX system piping work, ΔΔ system piping work, and XX system piping work.

  The local construction plan support system 10 is connected to a 3D-CAD database 20 that holds CAD data of facility design drawings and quantity data such as the quantity of necessary materials, and these CAD data and quantity per worker. Based on data such as digestion amount, for each construction section, for example, for piping work, calculate the work period of XX system piping work, △△ system piping work, and XX system piping work. A section-specific process 14 is automatically generated.

Next, the local construction progress confirmation system 12 will be described.
In this local construction progress confirmation system 12, paying attention to the point that the main work of construction always involves inspection, the construction progress is grasped in relation to the inspection situation.

For example, with regard to piping work, the main operations are pipe material loading, piping alignment work, welding work, etc. In order, non-destructive inspection, pressure test etc. are performed to check safety etc. Construction will be completed. For this reason, by making the database of the inspection status data in each construction section, this inspection status data can be used for confirming the construction progress status.
As shown in FIG. 1, in the local construction progress confirmation system 12, regarding the inspection schedule, data related to the execution schedule for each inspection item is accumulated in the inspection schedule database 22. Moreover, what has been inspected locally is stored in the inspection result database 24 as data relating to the inspection result for each inspection item. Then, the schedule and results are integrated for each inspection item, and are accumulated in the inspection probable database 26 as inspection progress data.

  In the inspection forecast database 26, the progress of the inspection is replaced with a percentage and also converted into a quantity (ton). For example, if non-destructive inspection, pressure-resistant inspection, and sequential inspection are completed in a specific piping work, the progress of the inspection is 100%, and the quantity of construction materials required for piping work in that construction section The quantity data is recorded as having been digested. If there are unsuccessful inspection items, the progress status is evaluated as a percentage in the inspection flow of all items, and repairs and other work are required. Therefore, it will be converted into the amount of construction materials already digested.

  In this manner, the inspection forecast database 26 transmits the data to the local construction plan support system 10 after converting the inspection progress into a quantity.

  The local construction plan support system 10 integrates the data obtained by converting the inspection progress into the quantity of construction material with the above-described section-by-section process 14, and generates the section-by-section process 14 'in which the section-by-section process 14 is updated.

  The updated section-specific process 14 ′ is displayed by the bar chart lightning display unit 30 as a process chart with a lightning display for visualizing the progress of the construction, for example, as a process chart as shown in FIG. 2.

  In this way, the progress of the local construction is visualized from the quantity side by the process chart with bar chart lightning display indicating how much quantity is digested against the schedule, specifically XX series The situation of plumbing work is delayed, but the situation can be grasped at a glance.

  Further, data obtained by converting the inspection progress status into the amount of construction material is transmitted from the inspection predictive database 26 to the 3D-CAD database 20. In the 3D-CAD database 20, the physical quantity conversion data of the progress of the inspection and the CAD data of the corresponding section are integrated. Based on the CAD data, the 3D-CAD progress display unit 32 displays a 3D graphic indicating the progress of the construction, for example, a color-coded display that can distinguish a pipe that has been inspected and a pipe that has not been inspected. Display.

  Such 3D graphic display makes it possible to visualize the progress of local construction with a more realistic sensation.

  Furthermore, the bar chart lightning display unit 30 may display a process table with lightning display and a construction section list as shown in FIG. In this construction zone list, the zones where construction delays have occurred from the updated zone-specific process 14 'are tabulated, and a display indicating the delay is attached so that the zones where progress delays are occurring can be seen at a glance. ing. This list makes it possible to understand at a glance which areas of the work are concentrated in the whole area, and manage the progress of the work not only in terms of quantity but also in terms of the construction area. To help.

Next, another embodiment of the present invention will be described with reference to FIG.
As shown in FIG. 4, when a process chart with a bar chart lightning display is displayed, information necessary for achieving the completion target is indicated by indicating the completion target date in the process where the construction delay occurs. Is automatically calculated, and a process follow-up table displaying the information is displayed. For example, if the work is delayed from the schedule for XX system piping, this process follow table will be displayed, so in the future, how many days will be required to complete the work, how much will be consumed, Information such as how many are displayed immediately. Thereby, information required for process management can be obtained instantaneously.

  In the above-mentioned system for confirming the progress of plant construction work, the headquarters where the system is installed is connected to the site via a line, so that timely progress confirmation and process progress can be maintained both locally and at the headquarters. Because it is possible to make a plan for material and personnel input to do so, high-precision construction management becomes possible.

  The present invention has been described with reference to a preferred embodiment. However, the present invention can be applied not only to power plants such as nuclear power plants and thermal power plants, but also to process management of various plant construction works. It is.
