Description

Technical Field

[0001] The utility model relates to the field of municipal cable protection devices, in particular to a municipal engineering cable protection device. Background Art

[0002] When laying cables in municipal engineering, protective tubes are generally used to protect them and increase their service life. General protective tubes are made of modified plastics, which are suitable for construction projects such as laying pipelines and cables in special areas such as roads, railways, buildings, and under riverbeds without the need for large amounts of mud and earth excavation or damage to the road surface. They are resistant to high temperatures and external pressures, but the existing protective tube structures are mostly plug-in when spliced. In order to increase their sealing properties, the gap of their plug-in mechanisms is small, resulting in greater friction during plug-in or adjustment and disassembly projects.
