Features

Data on cracks

  • The width, length, shape, 3D positional coordinates of cracks
  • 2D and 3D data

Technical Improvements

  • Measurement of crack width
    At a distance up to (m) 1.5 5 10 30 50 ･･･ 100 ･･･
    A width down to (mm) 0.007 0.022 0.044 0.132 0.221 ･･･ 0.441 ･･･
    *from a right angle
  • Distances of 1.5 up to 1000m are measurable without a reflector.
  • Compensation of collimation angle
    When we see the same width from some angles, they look different.
    Some of them look as they are, others thinner, as the pictures show.
    From a RIGHT angle From an OBLIQUE angle
    This phenomena is a problem for crack inspection,
    but KUMONOS automatically compensates the angle and gets the right width!!

Data Management

  • The data gathered is stored in the order of acquisition with the positional coordinates.
  • It is easier to make models of a bridge, wall, weir, building and an arched structure like a tunnel.
    Elevation, development, plan and 3D model are available.

Wide Inspection Range

  • Structures like the followings can be inspected by KUMONOS.
    • Buildings, bridge piers, retaining walls, dams, tunnels, concrete pavements and other concrete structures.
  • These places are no longer a problem.
    • Dangerous and inaccessible places
      like where a busy street or river runs in front of the objects.
    • Places where scaffold and a man-lift truck are not available.

Reductions

  • The gap between the real object and the data acquired.
    The gap range by old method ･･･ 18mm to 72.5mm approx. 1/30 at the max!!
      by new method
    with KUMONOS     		･･･ 1.8mm to 2.5mm
  • The labor of tracing
  • Injury risks
    It's because it is not necessary to work at an elevated place.
  • Cost
    Scaffold, a man-lift truck and the labor to prepare them are not necessary.

Other Advantages

  • Easy to keep track of cracks change across the ages.
  • Efficient analysis of structure endurance
  • Prepare proper repair plans
  • Efficient asset management etc
