Stakeout sideslopes

|

• Calculate and stake out positions of the point of intersection of the project side slope with the existing terrain.

• The stakeout position is calculated from the following information:

  • From the point position to the projection of the slope.

  • Distance to the stakeout element.

• Click Stakeout.

• Click Sideslopes.

  

• Select the horizontal alignment, from which the sideslope is defined.

  

  • Reference to stakeout.

    • Line (2 points): line defined by two topographic points. Requires to select Point 1 and Point 2.

    • Arc (3 points): arc defined by three topographic points. Requires to select Point 1, Point 2 and Point 3.

    • Arc (2 points+R): arc defined by two topographic points and by the radius. Requires to select Point 1, Point 2 and arc radius.

    • Drawing object: select a line, polyline, arc or circle in the graphic window. This option allows for example to stakeout a drawing element imported.

• Click Invert to invert the reference direction.

• Click Info to have information on the reference object.

  

• Click Select to pick the points directly from CAD or click Measure to measure the reference points.

• After the reference object has been selected click Next to define the parameters.

  

  • Chainage: distance on the reference element on which is the position to reach on the horizontal alignment from where the sideslope starts.

  • Interval: distance between the points along the reference element. Use the button on the right to calculate the interval dividing the length of the reference element in a defined number of parts.

  • Offset: distance perpendicular to the reference element. Use the button on the right to define if the sideslope is on the left or right side of the reference element.

  • Height diff.: elevation difference to apply to the calculated point. The software interpolates the elevation on the reference element with the defined station distance. A slope can be added to the interpolated elevation.

• Click Next to define the slopes.

  

• In this page we define the slope value in the cut or fill condition.

  • Cut: slope value in the cut condition (receiver elevation above the starting elevation of the slope).

  • Fill: slope value in the fill condition (receiver elevation under the starting elevation of the slope).

• Tap Next to start staking out of the calculated position.

• After having defined the reference element, the offset parameters and slopes, the main stakeout window appears.

  

• In addition to the visualization mode described in previous paragraphs, this graphical view contains the cross section of the side slope and current position.

• Click View mode and select Cross sections.

  

• This view shows the current cross section with the instrument position and the cut/fill design slopes.

  

• The side panel contains the information to get the point of intersection.

• The side panel contains the information to get the point of intersection.

• First value refers to the vertical distance from the position to side slope. Second value refers to the horizontal distance from the position to side slope.

  

• Third value shows the current value of the slope.

  

• Click to display the cut/fill value to achieve the project slope value.

  

• Click again to display the perpendicular distance to the point to achieve the project slope value.

  

• A scheme of the information is visualized in the picture below.
