Sewer rehabilitation

The use of the Curing Monitoring System enables you to increase the planning reliability of your renovation measure, to reduce follow-up costs, energy costs and CO2 emissions as well as to obtain a quality certificate for a professional sewer renovation.

The CMS technology is characterized by easy handling, robust system components and a high-performance software, which offers new possibilities for process control and quality certification for the installer and for the customer!

OSSCAD received the German patent in January 2010 and the US and European patent in 2012.

Importance for the sewer rehabilitation

Methods for the rehabilitation of pipe or sewer systems are so-called Cured-In-Place Pipe (CIPP). The CIPP process uses flexible hose carriers made of corrosion-resistant synthetic fibres (needled felt) or glass fibre reinforced plastic composite (GRP fibers) impregnated with a reaction resin molding compound. The installation in the channel takes place via the manholes, in which the hose (liner) is installed either by inversion or by feeder. Curing to a solid plastic pipe (liner) can be carried out by hot curing by means of hot water, steam or by UV light curing.

The structural and operational requirements

The structural and operational requirements for renovated sewers are high. The pipe lining processes are under special control and testing, as their production in the field takes place under difficult working conditions. Ensuring a consistent quality standard is verified after the build-up by acceptance tests. Quality defects on the liner at its installation may be caused for instance by local overheating (due to excessive polymerization of the resin, a too high heat supply or a faulty composition) or by an incomplete curing. The detection of abnormalities and their precise localization along the liner makes it difficult to accept and to sample liners. Due to the risk of sinks or inlets of cold groundwater, a safety margin in energy management is taken into account, which often leads to unnecessarily long heating times.

Unique features

The Curing Monitoring System CMS makes it possible to continuously measure the thermal curing of hose liners along its length in real time, to adapt the energy supply during rehabilitation measures and to provide a proof of quality for a professional curing.

System components of the CMS system

The CMS Controller can be supplied either as a mobile, portable unit for the use in the field or as 19‘‘ version for the installation in the truck of the company installing the liner.

The mobile CMS measurement device contains the under mentioned system components:

  • DTS controller
  • IPC with keyboard
  • VISCOM Liner Software
  • Optical connector (BlueBox) for the connection to the sensor cable
  • LAN socket
  • Socket for the energy supply

 

Powerful CMS Software

By using the CMS software (so called VISCOM Liner), the temperature measurement data can be prepared so that the user can assess and control the local and temporal curing process of the liner during the renovation process.

Standard views of the VISCOM Liner software are the so-called Zone View, the 3D Plot and the Curing View. The 3D Plot and the Curing View serve as proof of quality for a professional rehabilitation. The zone view provides the installer with clear decision criteria for the energy supply, so that the renovation can be completed successfully even on difficult construction sites.

CMS Sensor cable

The CMS sensor cable is designed to be drawn from a cable drum directly into the sewer.

To ensure the quickest possible connection of the sensor cable to the CMS controller at the construction site, the sensor cable is pre-assembled with an optical plug, so that the measuring system can be set up and is ready for use in a few simple steps.

Application fields of the CMS measurement system

The CMS measuring system is suitable for the Cured-In-Place Pipe (CIPP) renovation of waste water pipes (sewers) and pressure pipes (drinking water pipes).

Types of CMS Sensor cables

Depending on the diameter and the wall thickness of the CIPP liner, and taking into account the chosen curing process (water, steam and UV curing), different sensor cables are available for waste water and drinking water pipes to provide high mechanical protection for the glass fibre integrated in the sensor cable.
