technical field

The utility model relates to a forming mold for building components, in particular to a single-groove mold for cable grooves.

Background technique

The main method for substation power lines to be transported through underground cable trenches is to dig a trench with a certain depth and width from the ground, then build walls on both sides of the trench, and install cable bridges on the wall after the walls are solidified. At present, there are two general methods related to substation cable trenches: one is plastering cable trenches on the surface of brick masonry; the other is cast-in-place concrete cable trenches. The on-site construction procedures of the above-mentioned two kinds of cable trenches are complicated, the construction period is long, and the resource consumption is relatively large, resulting in site confusion and increased safety hazards, increasing management difficulties, which is not conducive to the development of safe and civilized construction, and the on-site construction may lead to the distribution of tie bars Inhomogeneity, uneven molding size, on-site mixing and maintenance of concrete are easily affected by the environment, on-site formwork is difficult, and it is difficult to ensure the smoothness of the concrete surface of the ditch, which has a negative impact on the long-term use of the ditch.

In response to the above problems, some prefabricated combined cable trenches have appeared at present, which have the advantages of pre-preparation and on-site assembly, and effectively solve various shortcomings of traditional cable trenches from excavation to forming. Cable trenches, and mold structures required for prefabrication are not disclosed.
