The invention discloses an electricity paving device for rapidly and smooth pavement along a curvilinear path, comprising a bottom plate; two short side holes are arranged on a short side part, and two long side holes are arranged on the long side part, the short side holes are symmetrical to the long side holes; when two bottom plates are abutted, the space between the short side holes and the long side holes is equal; upright posts are plugged in the short side holes and the long side holes, and upright post holes are arranged at the bottom parts of a short side plate and a long side plate; two positioning grooves in parallel to the short side are arranged on the bottom plate, and two positioning grooves are symmetrically arranged; a clapboard extended upwards is spliced in the positioning grooves, upper parts of the short side plate and the long side plate are buckled with cover plates with consistent shape as the bottom plate. The electricity paving device is reasonable in structure, able to extend and pave along a straight line as well as pave in an arch form at any time and any place according to the turning demand; the device is tight in leakage, smooth in transition, simple and fast in construction, high in efficiency, high in interphase safety of cables, small in placement space, convenient to transport, not easy to break; therefore, the electricity paving device is especially suitable for hilly area.
