Canal Renovtion Methods
The application for liner methods in gravity sewer renovation was developed in collaboration with the leading manufacturer of these materials, POliner Sp. z o.o. This tool supports designers and investors planning the renovation of gravity sewer pipes using the most popular trenchless technology – CIPP (Cured-In-Place Pipe), for sanitary, stormwater, and combined sewers, with circular and egg-shaped cross-sections.
The application allows for the estimation of the required thicknesses of felt and fiberglass liners in a few simple steps, based on the technical condition of the canal, its depth, and the groundwater level. The application also shows the differences in liner thicknesses according to the criterion of circumferential stiffness and DWA guidelines.
Another advantage of the application is its ability to show estimated hydraulic gains from the renovation – an increase in the canal’s capacity, allowing for the connection of additional users or the drainage of additional areas.
The application is available in Poland.
Selection of the channel renovation method
The following data should be prepared for the selection:
- the shape of the channel cross-section,
- the roughness coefficient,
- the slope of the section to be renovated in ‰.
Additionally, the type of channel to be renovated, the technical condition of the channel and the purpose of renovation should be specified.
The calculator allows you to select a channel renovation method for circular or egg-shaped gravity channels made of materials such as concrete, stoneware, brick, cast iron or plastic.
Results of selecting the channel renovation method
Based on the information provided, the calculator performs calculations and the results are presented in the form of a PDF report, which contains the calculation results and additional information about the proposed linings.
The report contains information about:
- channel parameters before renovation,
- estimated hydraulic gains from the renovation,
- summary of proposed renovation methods,
- proposed sleeve linings.
Additionally, it is possible to contact POliner directly for optimization and precise selection of the lining thickness.
