Abstract
Description
Technical Field
[0001] The utility model relates to a prefabricated conduit, in particular to a prefabricated conduit for power cables, belonging to the technical field of cable laying tools. Background Art
[0002] When laying existing power cables, in order to save ground space, they are usually laid underground. Therefore, generally, a prefabricated pipe gallery is built underground to uniformly accommodate the cables. However, the construction cost of the prefabricated pipe gallery is relatively high. So currently, a prefabricated conduit method has emerged to accommodate the cables. This prefabricated conduit is not a conventional pipeline, but a box formed by multiple holes. There are several such boxes, and the cables can be supported at fixed intervals. Compared with the pipe gallery, this method has lower cost and construction difficulty. However, due to the height difference in the cable preset groove, the boxes cannot be at the same height. When the cables pass through the boxes, they will inevitably tilt and extend in length, resulting in insufficient cable length. Therefore, further improvement is needed. Summary of the Utility Model
[0003] The purpose of the utility model is to solve the above-mentioned drawbacks and provide a prefabricated conduit for power cables, which is simple and fast to install, flexible in lifting and adjusting, strong in adaptability, and has a simple and reasonable structure.
