Hydroelectric power plants

3D laser scanning is also very important with hydroelectric power plants.

Based on 3D laser scanning data the following can be done:

  • Monitoring dam shifts and deformations
  • Monitoring shifts and deformations of the cuts and supply canal embankments
  • Monitoring the condition and changes in geometry of the supply tunnels
  • Design of the additional objects
  • Design of the secondary devices and machines on entrance structures
  • Monitoring shifts and deformations on entrance structures and machinery compartments
  • A tremendous advantage of spatial scanning over other methods of auscultation is in monitoring shifts and deformations of the structures in the whole, on its entire surface, while standard methods will show shifts only at chosen points. Standard surveying cannot show what happens between these points. Although standard surveying is more accurate, the mentioned limitations are a huge disadvantage, particularly with clay objects.
  • Monitoring shifts and deformations is based on repeated surveying within certain time intervals.
  • A polygonal model of the structure is made for each survey, which is then compared with the primary or any other of the previous models (conditions).
