Prefabricated assembly type cable duct bank

The utility model discloses a prefabricated assembly type cable duct bank which comprises a cable duct bank formed by splicing a plurality of prefabricated assembly type bodies, each prefabricated assembly type body comprises a reinforced concrete member formed by one-time pouring of cement, and a plurality of through holes and limiting holes which penetrate through the reinforced concrete membersare formed in the reinforced concrete members. A tube bank for erecting a cable is embedded in the through hole, limiting pieces matched with the limiting holes are arranged at the limiting holes ofthe prefabricated assembly type bodies, and the adjacent prefabricated assembly type bodies are tightly attached. The reinforced concrete member is of a cuboid structure; studs are symmetrically arranged at the joints of the side faces of the reinforced concrete components. Two adjacent reinforced concrete components are connected in the mode that opposite-pull screws penetrate through the two adjacent studs. According to
