Prefabricated cable trench

The utility model relates to the technical field of cable laying, in particular to a prefabricated cable trench which comprises a cable trench mechanism and a planting groove mechanism arranged on one side of the cable trench mechanism, and the cable trench mechanism is detachably connected with the planting groove mechanism in an inserting, hanging or bolt mode. Wherein a sand stabilization layer, a planting layer and a water retention layer are sequentially arranged in the planting groove mechanism from top to bottom. According to the prefabricated cable trench, the cable trench mechanism and the planting groove mechanism are integrated, the cable laying requirement is met, meanwhile, appropriate plants can be selected through the planting groove mechanism, the greening and beautifying functions are taken into consideration, the wind prevention and sand fixation effects are achieved in the Sagomei region, the sand fixation and greening functions are integrated, and the good environment protection effect is
