Multipurpose electric power channel

Abstract

The invention discloses a multipurpose electric power channel which comprises a bottom plate. Two short-edge holes are formed in a short-edge portion of the bottom plate, two long-edge holes are formed in a long-edge portion of the bottom plate, and the short-edge holes and the long-edge holes are symmetrically formed; the distances from the short-edge holes to the long-edge holes are equal to one another when two bottom plates are butted to each other, upright columns are inserted in the short-edge holes and the long-edge holes, upright column holes are formed in the bottom of a short-edge plate and the bottom of a long-edge plate, two positioning grooves which are parallel to a short edge are formed in the bottom plate and are symmetrically formed, partition plates which upwardly extend are inserted in the positioning grooves, a cover plate is fastened on the upper portion of the short-edge plate and the upper portion of the long-edge plate, and the shape of the cover plate is consistent with that of the bottom plate. The multipurpose electric power channel has the advantages that the multipurpose electric power channel is reasonable in structure, not only can be extensively laid along straight lines, but also can be laid to form arcs according to turning requirements in any places at any time, is tight in connection, smooth in transition and high in efficiency and can be easily and quickly constructed, and cables are high in inter-phase safety; the multipurpose electric power channel is small in occupied storage space, convenient to transport, difficult to damage and particularly suitable to be used in hilly regions.

Description

technical field [0001] The present invention relates to a multipurpose power tank. Background technique [0002] With the gradual improvement of urban power supply quality requirements, the current domestic urban high-voltage power supply mode has basically completed the conversion from high-voltage overhead line power supply to underground high-voltage power supply. Underground high-voltage power supply mainly includes two forms: underground pipe frame high-voltage power supply and underground pipeline high-voltage power supply. Among them, the high-voltage power supply in underground trenches requires the laying of high-voltage cable ducts containing high-voltage cables underground. [0003] The power system has made industrial construction regulations for the laying of high-voltage cable pipelines, specifically: 1. The buried depth of cable climbing poles and towers must be increased reasonably according to the specific conditions on site. To meet the requirements of th...

Problems solved by technology

However, the disadvantages of this kind of high-voltage cable groove are: 1. It is only suitable for laying straight cable ducts. When the cable duct turns, it can only make a right-angle turn. Either cut and shape the grooves of the prefabricated high-voltage cables on-site so that the butt joints of the prefabricated high-voltage cable ducts at the corners are flush, which is difficult and time-consuming to process on site; or leave gaps between the prefabricated high-voltage cable ducts at the corners To meet the turning requirements, but after such use, there will inevitably be water leakage and soil leakage in the gaps, which will eventually lead to the filling of the cable duct with sand, which not only does not meet the construction requirements, but also brings troubles to future cable maintenance and transformation; 2. Because the cross-section of the prefabricated high-voltage cable duct is U-shaped, it takes up a lot of space and is extremely inconvenient during transportation and storage. Moreover, this structure has low impact resistance and is easily damaged by force; 3. Inside the prefabricated high-voltage cable duct There is no spacing device, and three single-core cables are laid in the same groove, which will cause the contact between the phases of the cables and easily cause cable accidents; 4. When the grooved line turns, the joints of the prefabricated high-voltage cable grooves will be To form gaps of different sizes, additional on-site caulking construction is required, otherwise, soil leakage and mud leakage will occur when the soil flows into the trench cavity, which will seriously affect the safety of cables or optical cables in the pipeline; 5. The terrain of coastal cities The landform is generally dominated by mountainous or hilly areas, with many curves, and most of the roads are curved around mountains or hills.

Obviously, the traditional prefabricated high-voltage cable ducts are not suitable for construction in these areas. Soil and mud leakage will inevitably occur in the gaps between the prefabricated high-voltage cable ducts at the corners, and eventually the cable ducts will be filled with mud. Sand, not only does not meet the construction requirements, but also brings troubles to cable maintenance and transformation in the future;
