Power, Telecom & Utility Construction

The same maintenance team may work in hard roads in the city in the morning and enter fields or hills in the afternoon, with very different vehicle, ground and public risks.If only fixed and single-specified plates are carried, they are not available at long distances and soft land, and narrow communities may not be able to lay or move.The project should establish a pre-workspace questionnaire to record at least the width of the entry, the type of ground, underground facilities, the weight of equipment, the retroactivity of the legs and the expected length of stay;Selection of panels by scene, Outrigger Pads, connector and alert attachment before departure.After the transfer, the numbering, examination of the damage and the state of cleanliness are counted to prevent the mud or contaminants from being brought to the next site at the previous site.

Under the roads of the densely populated areas of public facilities, there may be cables, communication pipelines, drainage wells and backfilling strips, and the integrity of the surface does not mean that it can withstand heavy vehicles or legs.The partial destruction of the arm vehicle and the vehicle ' s suspension, if they were to be placed within the influence of a well cover, road stone or ditch, would endanger both the stability of the equipment and the established facilities.The underground drawings should be checked and field marked prior to the operation, and the safety distance should be increased or structurally verified if it is not possible to confirm.(b) The bottom of the pad must be flat, continuously charged and not emptied;Review levels and depositions after changes in the arm, rotation and payload of equipment.The treatment of “underground pipes, wells and trenches which make surface carrying difficult” cannot be limited to a single pass, but also covers the maximum load, maximum frequency, worst weather and evacuation phases.It is recommended that representative positions be selected for trial, that ground, vehicle or equipment data be recorded and that the scope, connection and frequency of maintenance be adjusted to the results;Changes in conditions have confirmed that early experience is not directly applied to the entire electrical, communications and public facilities construction project.

Wind, ice or post-disaster circuits are required to quickly restore electricity and communications, and on-site lighting, roads and information are often incomplete.(a) A rush to enter may lead to vehicles being trapped on wet soft shoulder or to high-altitude operations without full legs;Once access is blocked, follow-up personnel and materials cannot be reached.The recovery team should prepare modular panels and Outrigger Pads at normal times, with a minimum length of preparation, rapid connection, night marking and review process.The rescue and evacuation route should be secured after arrival, the equipment station should be installed and any apparent deposition, slide or sew open should trigger a pause and reassessment.The construction site for electricity, communications and public utilities should set clear standards for the discontinuation of “short power outages and often affected by bad weather”, such as continued uplifting of plates, incomplete support surfaces, extended depositions, visible slippages of vehicles or loose connections.Unusual isolation and unloading were detected, and then the floors were repaired or reconfigured, and temporary pads were prohibited in carrying conditions.The head of the mission may not resume operations until he or she has been qualified to do so, and records of disposal are maintained.
