AI Technical Summary
Existing prefabricated power trenches are prone to water accumulation in areas with high rainfall or abundant groundwater, resulting in backflow or seepage at drainage outlets, which affects line safety and has low cable fixing efficiency.
An assembled power trench with prefabricated sections and cover plates arranged in an alternating pattern was designed. Drainage sections and diversion channels were set up, and diversion pipes and longitudinal support plates were used. Combined with pipe racks and grounding embedded parts, the sealing performance and cable laying efficiency were improved.
It effectively reduces the risk of water backflow, improves sealing and construction efficiency, protects cables from water damage, and ensures line safety.

Abstract
Claims
1. A fabricated electrical power trench, characterized by, It includes prefabricated sections and cover plates. The prefabricated sections include standard sections and drainage sections. The prefabricated sections have a U-shaped cross-section and a raised strip on the inner side of the top. The cover plates have downward raised strips on both sides. The cover plates are staggered with the prefabricated sections during installation, and the joint between the two cover plates is located in the central area of the prefabricated sections.
2. The fabricated power trench of claim 1, wherein, A horizontal protrusion is provided on the inner side of one end face of the precast section, and a horizontal groove is provided on the other end face.
3. The fabricated power trench of claim 1, wherein, At least one connecting groove is provided on each side of the precast section near the two end faces, and a through hole is provided between the connecting groove and the end face.
4. The fabricated power trench of claim 1, wherein, A flow guide channel is provided at the center of the bottom of the precast section, and the flow guide channel is parallel to the direction of trench laying.
5. The prefabricated power trench according to claim 4, characterized in that, A drain outlet is provided in the guide groove of the drainage section, and a guide pipe is provided below the drain outlet.
6. The fabricated power trench of claim 4, wherein, Several longitudinal support plates are provided at the bottom of the prefabricated section. The longitudinal support plates are perpendicular to the guide channel. The longitudinal support plates are provided with at least one interruption groove. A pad is provided on the longitudinal support plate. The pad is provided with openings or slots.
7. The fabricated power trench of claim 1, wherein, The prefabricated section has a protruding edge at the middle of the inner side of both sides; the assembled power trench also includes a pipe rack, which includes a central plate and several limiting rods. The width of the central plate is the same as the inner width of the upper part of both sides of the drainage section. An opening or slot is provided on the central plate. The limiting rods pass through the central plate, with their bottoms contacting the bottom of the inner side of the drainage section and their tops extending below the cover plate.
8. The fabricated power trench of claim 1, wherein, The cover plate has grooves at its four corners, and lifting rings are installed in the grooves. The top of the lifting rings is flush with the cover plate.
