Specifies the parameters for a trench or a ditch run. The available parameters change depending on the selected placement method.

Properties

Opens the Trench Run Properties Dialog. You use this dialog box to specify additional properties, such as material and material grade, which you cannot set on the ribbon.

Path

Displays the Create Path Ribbon, which defines the path along which the trench or the ditch is projected.

  • When you are placing branched trench runs, either the start or the end of the path must have an associated point-relationship with the path of a header trench run that you have already placed. This ensures that an opening is created at the intersection of the trenches.

  • You cannot define a curved path for the trench run, as curved trenches are unsupported. Additionally, you cannot route a vertical trench path.

Finish

Places the trench using the defined parameters.

Cardinal Point

Specifies the position of the trench cross-section relative to the path of the trench run. The cross-section is swept along the path. Select one of the following:

At rim elevation:

At invert elevation:

Top Left

Top Center

Top Right

Bottom Left

Bottom Center

Bottom Right

Placement Method

Specifies the method used to calculate the slope and depth of the trench.

The following methods are used with top cardinal points when the path is drawn at the top of the trench. These methods calculate the slope of the bottom surface of the trench. Select one of the following:

Define start and end invert elevation - The bottom slope and the depth are calculated by the software. See Place a trench by top cardinal point and invert elevations.

Define start depth and end invert elevation - The bottom slope and all other depths are calculated by the software. See Place a trench by top cardinal point, start depth, and end invert elevation.

Define start invert elevation and bottom slope - The depth is calculated by the software. See Place a trench by top cardinal point, start invert elevation, and bottom slope.

Define start depth and bottom slope - All other depths are calculated by the software. See Place trench by top cardinal point, start depth, and bottom slope.

Define start depth (Bottom slope is parallel to top slope) - SSee Place a trench by top cardinal point and start depth with bottom slope parallel to top slope.

The following methods are used with bottom cardinal points. These methods calculate the slope of the top of the trench. Select one of the following:

Define start depth and top slope - All other depths are calculated by the software. See Place a trench by bottom cardinal point and top slope.

Define start depth (Top slope is parallel to bottom slope) - See Place a trench by bottom cardinal point with top slope parallel to bottom slope.

Start Invert Elevation

Specifies the invert elevation at the starting point of the path. Invert elevation is the elevation at the top of the footing of the trench. Type a value with respect to the global coordinate system.

End Invert Elevation

Specifies the invert elevation at the end point of the path. Invert elevation is the elevation at the top of the footing of the trench. Type a value with respect to the global coordinate system.

Bottom Slope

Specifies the slope at the bottom of the trench. Type a negative value for a clockwise slope and a positive value for a counter-clockwise slope. This value is not available when both Start Invert Elevation and End Invert Elevation are specified.

Top Slope

Specifies the slope at the top of the trench. Type a negative value for a clockwise slope and a positive value for a counter-clockwise slope. The value of the top slope must not exceed 60 horizontal degrees. This value is not available when Top Left, Top Center, or Top Right is selected for Cardinal Point.

System

Specifies the parent system for the trench. Systems are defined using the Systems and Specifications task.

Name

Specifies the name of the trench. Type a name, or leave blank to use the naming rule.

Type

Specifies the type of trench, such as Cable Trench U-Shape, Piping Trench U-Shape, and Ditch U-Shape. Types are defined in the catalog.

You cannot modify the trench type of a trench run after placement.

Cross-Section

Specifies the trench cross-section. Each trench type has a set of cross-sections defined in the catalog.
