CUS 3D Manhole Survey and Inspection

The complete measuring system includes a mobile inspection vehicle and the CUS inspection robot. After placing the CUS robot on the manhole, the sensor unit surveys the manhole from top (cover) down to bottom (invert). A laser measuring system grabs all relevant surveying data. At the same time the integrated CCD color inspection camera with twentyfold zoom placed in the sensor unit takes high-res pictures and videos of the structural manhole condition. All actions are performed by the inspector from within the control room. CUS surveys all data in 3D Coordinate System (X, Y location plus local elevation) and guarantees highest possible and constant quality of surveying and inspection data acquisition. The CUS software stores all surveying and inspection data into a database and prepares them for further processing. After completion of the manhole inspection, CUS generates a complete report including the measuring data, a shaft sketch, additional pictures and videos from the manhole. The measured data are stored in a Microsoft SQL Server database and can be managed easily under Windows 2000 and XP Home/Professional. Using the manhole & shaft surveying system CUS gives you the best control and information over the municipal sewage system. Additional Information: CUS Manhole Survey & Inspection Results

Surveying special shaft structures

Even more and more cities, communities, municipal authorities and engineering consultants appreciate the quality of three-dimensional surveying and inspection of large manholes and special structures with System CUS. Manhole structures with angles of up to 100m and 25m of depth can be measured and inspected with CUS without any post processing works. Surveying, inspection and reporting is similar to standard manholes, which guarantees a frictionless import of the data in the sewer network database. As a result of the CUS manhole inspection you will get: Inspection report with manhole sketch (optional section) and pictures of structural condition Inspection report as PDF file Inspection video in MPEG4 file format Pictures in JPG file format Sketch in Autodesk DWG or DXF drawing file format Attributive data as ASCII CSV flat file format

Advantages over manual inspection

• Automatic on-site checks on diameter, material, slope, direction, profile during survey. This reduces mistakes and postprocessing works compared to manual inspection methods.
• Automatic on-site checks of sewage network topology.
• Automatic generation of a precise as built drawing for the complete sewer network, as a result of the CUS 3D-survey.
• Data recording for large manholes, special structures or polygonal and oval manholes is analog to standard manholes which guarantees a consistent integration into any CAD and GIS system.
• TV inspection results - e.g. german ATV-DVWK tokens PA and PE - can be allocated with their accurate layout positions.
• TV inspection results can be compared with real sewer pipe lengths. Sewer pipe requirements can be checked accurately, e.g. +- 25 cm accuracy according to German ATV-DVWK for inspection events like connection or branch pieces.
• CUS survey is independent from flow and weather conditions. Surveying during full manhole activity is possible. Deposits or sediments on pipe inverts do not falsify results.
• Many worksite safety requirements are not required. With CUS surveying and inspection system the inspection personnel does not need to step into manholes. No risk for inspection personnel.
• CUS guarantees highest constant quality for the results.
• CUS affords simple export of all digital inspection data to any common sewage database system without post-processing works.
• Digital Pictures (JPEG, GIF, TIFF) and Video Documentation (MPEG1, MPEG4, DivX) of the manhole's condition are an indispensable help for establishment of maintenance or rehabilitation programs.
