Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated cable trenches, in particular to a prefabricated cable trench mould which is compatible with various specifications and sizes. Background Art

[0002] The cable trench is one of the important infrastructures of the substation. It is usually arranged in the open air with a cover on the top. The trench is shallowly buried below the surface and the cables are laid inside. The traditional cable trench adopts a brick masonry structure or a cast-in-place concrete structure, which has the disadvantages of long construction period, high labor consumption, and difficulty in ensuring construction accuracy.

[0003] With the rapid development of building industrialization, in order to realize the concept of "standardized design, factory processing, and modular construction", prefabricated cable trenches have been promoted and applied. This type of cable trench effectively reduces on-site wet operations, improves mechanized construction efficiency, reduces labor input, and shortens the construction period. The construction process of prefabricated cable trenches is factory prefabrication, and the cable trench monomers are spliced ​​one by one on site.

[0004] At present, in order to facilitate mass production, factories usually only use one mold for single production and the prefabricated size cannot be adjusted, resulting in the same specifications of prefabricated cable trenches. When cable trenches of different specifications need to be prefabricated, the mold needs to be replaced for prefabrication production, which reduces production efficiency and is labor-intensive and time-consuming.
