Hydraulic characteristics of pipelines restored using polymer hoses
Aging water supply and wastewater pipeline systems suffer from corrosion and damage. Trenchless restoration methods extend their lifespan and reduce repairing costs. However, there is no standard method for determining the hydraulic characteristics of restored pipelines, making it challenging to assess the feasibility of using different materials for restoration. This article focuses on changes in hydraulic characteristics after restoring pipelines with glass fiber and synthetic felt hoses. The study uses Bernoulli’s equation and the Chezy formula to estimate changes in the flow capacity of pipelines. Standard values for slopes, flow rates, and filling rates were used to calculate the hydraulic resistance coefficient, Chezy coefficient, and flow rate after laying polymer hoses. The results show that the flow capacity of restored pipelines increases, and there is no need for further hydraulic calculations to confirm the absence of a reduction in pipeline capacity after restoration. Therefore, trenchless restoration methods can be considered as effective means to extend the lifespan of aging pipeline systems and reduce engineering repairs costs.
