Instructions for use

Pipe Burst Analysis is a 3D Network Analysis feature that simulates the exposure of a pipeline to damage or failure. The Pipe Burst Analysis can be used to find the position of the nearest valve upstream or downstream of the pipe burst point, and quickly find the nearest and least number of valves to be closed in the upstream according to the indication of the pipe flow direction. After these valves are closed, the burst pipe section is no longer connected with its upstream, which can prevent the outflow of water, thus preventing the aggravation of the disaster and the waste of resources.

After the Pipe Burst Analysis instance is created, it will automatically Turn on the underground mode, and the squib water spray effect can only be seen by adjusting the viewing angle to the underground. The Import Symbol library is required to create a Pipe Burst Analysis for building 3D pipeline Model Data.

Function entrance

• Spatial Analysis tab-> Facility Network Analysis group-> Network Analysis Drop-down Button-> Pipe Burst Analysis Button

Operation steps

1. Opens the 3D Network Dataset in the scene for analysis.
2. Click Spatial Analysis tab-> Facility Network Analysis group-> Network Analysis Drop-down Button-> Pipe Burst Analysis Button, The 3D Instance Management and 3D Environment Settings panels pop up . In the 3D Environment Settings window, you can set the Analysis Parameters, such as Weight Field, Node/Edge ID Field, etc.
3. Before Pipe Burst Analysis, you need to import a symbol library containing pipeline flow direction symbols, pipeline connector Model Symbols, and so on, to build a 3D pipeline model.
   • If the connector model and pipeline model fields exist in the 3D Network Dataset, after the Import Symbol Library, according to the connector model, pipeline model, and Joint Model Rotate and scaling fields, Create two Custom Thematic Map respectively and display them in the current Scene.
4. Create a Pipe Burst Analysis instance, which will automatically Turn on the underground mode , and the default transparency is 50%.
5. In the Instance Management window, you can perform Parameter Settings of Pipe Burst Analysis, including pipe burst point management, Pipe Burst Settings, etc.
6. Pipe burst point management: add and modify pipe burst points in the current 3D Network data layer.
   • Add by Mouse : Click Add by in the toolbar inside the Instance Management panel Mouse button, then move the mouse to Scene, click the left mouse button to add the bursting point, the bursting point will be displayed in the bursting point directory in real time, and click the right mouse button to end the addition.
   • The Pipe Burst Analysis can only analyze one bursting point at a time.
7. Pipe Burst Settings: Click Parameter in the toolbar inside the Instance Management panel The Settings button pops up the Pipe Burst Settings dialog box to set the Pipe Burst Analysis parameters.
   • Analysis Type: Used to set the type of Pipe Burst Analysis. Supports Find Closest Valve, Find Critical Down stream Nodes, Find Down stream Facility for Burst Point, Find Down stream Facility Closest to Valve four Analysis Types.
     • Find Closest Valve: Find the Critical Nodes nearest to the upstream of the pipe burst point.
     • Find Critical Down stream Nodes: Find the Critical Nodes nearest to the downstream of the pipe burst point.
     • Find Down stream Facility for Burst Point: Find all arc segments and nodes downstream of the pipe burst point.
     • Find Downstream Facility Closest to Valve: Find the nearest upstream Critical Nodes and the affected downstream arcs and nodes.
       Hint:

       When the Find Critical Down stream Nodes "or Find Down stream Facility Closest to Valve" option is checked, The "Find Closest Valve" "option will be automatically checked, and the two Analysis Types need to find the upstream Critical Nodes of the pipe burst point at the same time.

8. Valve identification field: Select the valve identification field (numeric type) in Point Dataset. Where nodes that are greater than 0 are valves and nodes that are Is no more than 0 are not valves.
9. After Parameter Settings, click the Execute button in the toolbar to execute the Pipe Burst Analysis.
