The results show that the one-dimensional full-flow model based on Preissmann slit hypothesis can effectively simulate the flow process of underground drainage pipes in substations, and provide technical support for flood prevention and waterlogging early warning of substations in humid areas.Fang, ...
Firstly, the wave and flow loads on inclined pipes were examined through tests in circulating water flumes. Next, the unsteady Reynolds-averaged Navier-Stokes (RANS) equations were adopted to numerically simulate the test conditions. Multiple factors were taken into consideration: immersion depth, ...
According to the results, the maximum velocity distribution in the flow field of flocking drainage pipes is closely related to the transverse distance h of the fluff, while the longitudinal distance h of the fluff causes little effect; when the transverse distance h of the fluff is less than ...
we’ve been serving the local community with pride and precision for over a decade. We know exactly what we’re doing regarding plumbing and drain services. Our team has experience working with various types of pipes and drainage systems, so that we can handle any repair or installation accord...

Watch Out for Tree Roots Outdoor drainage systems can end up with problems from wandering tree roots. More than a simple clog, these tree roots can significantly damage your pipes and cause expensive repairs. If you’re concerned about your tree roots and outdoor drainage, speak with a landsc...
Secondly, for the case of surcharging flow from the manhole to the floodplain, we account explicitly for four different contributions to the overall head losses between the pipe and the surface, similar to Bazin et al. (2014) for flow exchange between a street and an underground drainage pipe...
This indicates that the soil pipes may decrease the slope failure susceptibility by enhancing the effective slope drainage and the pore water dissipation, despite the observation of pipe remnants at landslide scars. Tsukamoto et al. (1982), Pierson (1983) and McDonnell (1990a) proposed scenarios ...
The model-generated initial profile might be selected after a period of no infiltration during which most of the drainage from the column has occurred. The influence of the initial condition diminishes as the simulation progresses, so that errors associated with selecting the initial condition ...
High-Pressure Cleaning Capability: This Amjet gasoline high pressure washer is designed for heavy-duty cleaning tasks, with a maximum pressure of 30 MPA and a flow rate of 65-40 Lpm, making it suitable for cleaning sewage pipes and other tough applications. Remote Wireless Control: The machine...
