Electricity paving device for rapidly and smooth pavement along curvilinear path

Abstract

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.

Description

technical field [0001] The invention relates to a power laying device capable of fast and smooth laying along a curved track. 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 conditio...

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;
