AI Technical Summary
Existing trenchless pipe dredging devices often experience problems when removing silt, as the silt spreads from the center outwards, forming deposits that adhere to the pipe walls, leading to the device becoming easily stuck and worn.
The system employs a main sludge removal component and an auxiliary sludge removal component working in tandem. The main sludge removal component breaks down hard blockages from the center of the pipeline, while the auxiliary sludge removal components, positioned by the support components, perform sludge removal from the outside in, limiting the concentration of silt along the pipeline axis and preventing its spread. Combined with the design of flexible guide components, it adapts to complex pipeline environments.
It effectively prevents silt from spreading to the pipe wall, reduces the risk of equipment wear, improves siltation efficiency, and enhances the ability to adapt to complex pipelines.
