ABSTRACT
Hydroelectric power plants and drinking water facilities are part of the critical infrastructure. As essential suppliers of energy and water, they are subject to high security and monitoring requirements. The structures must be inspected at regular intervals during construction and operation in accordance with water rights laws and operator specifications. The tunnel systems of hydraulic engineering facilities in particular must be inspected and documented over their entire life cycle in order to ensure faultless and efficient operation and to support renovation measures. However, many of today’s systems are very old and have never been comprehensively documented. Due to their exposure (slope), accessibility (diameter, inspection entrance) and sometimes severe surface damages, working in them is often challenging. Dibit has developed special 3D scanning systems for hydraulic engineering applications that enable comprehensive 360-degree measurement and documentation of the surface. Thanks to the modular and robust design, the systems can be roped down through maintenance holes and assembled in the tunnel if necessary. They can be used in confined spaces and, if necessary, transported using cable winches or lifting platforms on steep gradients or in vertical shafts.
