Is it necessary to pave temporary roads for the construction of cable trenches in the light-voltage zone?

The objective of the construction of the cable trenches in the light-voltage area is to allow the construction vehicles to move within the controlled route, while avoiding turning ground protection into equipment stabilization. In the area surrounding the construction of light-volt stands, components, cables and reversible equipment, the topic is concerned with “Does the construction of cable trenches in the photovoltaic field require the laying of temporary roads” and should, in particular, check the extent to which the feeder has been overloaded or evened. Where there is a gutter, backfilling area, slope or unknown underground facility on the route, the treatment must first be confirmed by the responsible party of the project.

The input information can be organized by the four columns of equipment, ground, route and time, with emphasis on the construction vehicle weight, the size of the tripod, the frequency of the component transport, the drainage course, the thickness of the topsoil, the location of the underground cable and the restoration requirements. To change the level of the equipment for overloading or uneven deposition of the nodes, it is proposed to process the drainage and soft points, then lay them out from the stable end and test them. In the case of leg pads, the maximum repulsive force of the leg provided by the plant must be obtained, and in the case of passage roads, the total weight of the vehicle, the axle, the tyre and the complete turn track should be used. With regard to the “requirement of temporary roads for the construction of cable trenches in the light-voltage zone”, the information review should also include the maximum vehicle profile, internal wheel differentials and side safety residuals for the core, and include missing information as an item to be confirmed in the quotation and construction programme.

The construction organization is as important as the product specifications. Operators should use means of moving a single load, with the vehicle being directed by a commander, without brakes, in situ wheeling or constant pressure. The light-voltage area, which is usually large and revolving, must first protect drainage and topsoil and then move pavements in accordance with the construction phase. Changes in traffic routes, repositioning of equipment or heavy rainfall are followed by a re-examination of the continued applicability of the original programme. The trial-padging record of “Does the construction of a temporary road need to be completed in a light-voltage area” should indicate the starting and ending position, vehicle status and release conclusions to facilitate review as construction conditions change.

The inspection cycle can be shortened at an early stage of use and then stabilized before adjusting to vehicle cycles and weather. The maintenance staff focused on sub-board pumping mud, surface pressure, drainage congestion, loose connection, underground cable marking, contamination and revegetation, as well as on the driver ' s compliance with speed limits and shift requirements. Any unconfirmed sub-board support, edge instability or foot contact should first be disabled. For the construction of a temporary road around a cable ditch in the light-voltage area, the inspection form is to vary the level of the equipment by overloading or uneven deposition at a single branch point, with an indication of the inspector and the time of return.

The offers from different suppliers should be compared under the same size, material, connection, packaging, delivery and test basis. Supplementation should be requested if the maximum load is given without a description of the ground, distance and load. Energy projects should also focus on batch consistency, port efficiency, repairability and container loading. This retrodiscussion should also answer “Does the construction of cable trenches in the photovoltaic field require the laying of temporary roads” or “does it have to be improved by first processing drainage and soft points, then from the preparation and trialing of the stabilization end, so as to avoid a subjective description of the closing item?

If the conditions on the ground are different from the assumptions in this paper, the application of the conclusions should be suspended and reassessed. Energy transport, suspension, refurbishment and overhaul are subject to project programmes, equipment manuals and statutory requirements. The supplier may assist in matching the product, but the final placement, commissioning and release shall be approved by the responsible party for the project.
