Construction requirements for power poles of China Telecom and communication projects
construction safety requirements
1.1 High-altitude safety measures for laying optical cables on combined poles
1.1.1 Any operations such as laying optical cables and installing appliances at a height of more than 2 meters from power poles should be regarded as high-altitude operations, and the operation of high-altitude operations should be carried out in accordance with relevant safety production regulations.
1.1.2 Personnel participating in high-altitude work should undergo a physical examination, and those with symptoms that are not suitable for high-altitude work shall not participate in high-altitude work.
1.1.3 Qualified safety belts must be used when working at heights. The safety belts must be fastened to the specified components, and must not be used at low heights. Tools and materials for high-altitude operations should be placed in a tool bag or tied up and down with ropes, and it is strictly forbidden to throw them.
1.1.4 The high-altitude operator shall not remove the protective measures when transferring the working position, and the supporting member held by the hand must be firm.
1.2 Safety measures for live operation of optical cable laying
1.2.1 Strictly follow the safety distance specified in the communication design specification. The minimum distance for installing optical cables on power poles below 10KV is 2.5m.
1.2.2 Live work should be carried out in good weather. In case of lightning, snow, hail, rain, fog, wind force greater than level 5, or humidity greater than 80%, construction is not allowed.
1.2.3 The construction process should be signed for live work, and the issuer and the person in charge of construction should have practical experience in live work.
1.2.4 Live work must be guarded by a special person, and the guardian should have practical experience in live work. The guardian shall not directly participate in the construction operation, and the scope of guardianship shall not exceed one point.
1.2.5 During the construction of the line, a special person shall be assigned to be responsible for the maintenance of safety and public security, and the operation shall be carried out in strict accordance with the safety regulations, and illegal operations and brutal construction are strictly prohibited.
1.3 The construction operators must have the qualification certificate (ascending certificate) of special operators, have undergone power safety training, and have mastered the common sense of power safety.
1.4 The project management personnel and the construction team leader shall inform the construction personnel of the specific safety measures for the construction of the project before starting the construction, and there must be measures and plans to prevent contact with nearby power lines and other facilities.
1.5 Construction workers should check safety helmets, safety belts, insulating shoes, insulating gloves, test pens, high-voltage electroscopes, test ladders, foot buckles, hanging plates and ropes before going to work to ensure that there is no damage. The safety helmets, safety belts, insulating shoes, insulating gloves and insulating tools used must meet the requirements of the national safety production standards.
1.6 When erecting optical cables in combination with power lines, at least 2 people should be in a group at each independent construction site.
1.7 In addition to ensuring a safe distance of 2.5m between the optical cable and the power line, the construction unit also needs to prepare a special power outage construction plan, and apply to the power supply department for power outage before construction. Submit an application for power outage to the power supply department where the construction is located, and start construction after obtaining permission for the outage.
1.8 Workers must wear safety helmets, insulating gloves, insulating shoes and use insulating tools during construction.
1.9 Before erecting optical cables on power poles, other cables, poles, and cables other than power lines on the power poles should be checked for electricity to confirm that they are not live before operation.
1.10 When working on the power pole, the operator must pay attention to keeping a certain distance from other lines such as power lines, and treat them as power lines until the nature of the use of the cable is not clearly identified.
1.11 It is strictly forbidden for operators and tools to contact the power line. When installing and fixing the optical cable, the distance from the power line should not be less than 2.5m.
1.12 If there is a power line that intersects with the pole road erected by the combined pole, the laid optical cable should pass through the lower part of the lowermost power line, and the distance should be kept at 2.5m. It is strictly forbidden to lay the optical cable above the power line.
1.13 When the communication line is in contact with the power line or the power line falls on the ground, all related operations must be stopped immediately to protect the site and prohibit pedestrians from entering the dangerous area. Do not use common tools to touch communication cables or power lines, and immediately report to the person in charge of the construction project and designated professionals to eliminate the accident. Before the accident is eliminated, do not resume operations without authorization.
1.14 Before working on a building with a metal ceiling, it should be confirmed that there is no electricity after the application of electricity inspection test.
1.15 Re-test the survey route according to the design drawings to understand the quality of power poles and construction safety. If the power pole is tilted or damaged, which does not meet the requirements of the specification, it will affect the safety of construction, and construction cannot be carried out. It should be recorded and reported to the construction unit to change the design.
1.16 During the construction process, pay attention to protect the original pole road, and do not damage the original cables on the pole road, which will cause the line to be interrupted during the construction process.
1.17 Before climbing the pole, check again whether there are power lines, electrical equipment or other obstacles that affect the climbing and operation of the pole, etc., and two people are not allowed to go up and down the pole at the same time.
1.17.1 Safety belts must be worn when using the foot buckle to go up and down the pole. Do not carry heavy materials and tools when going up and down the pole. Carry a tool bag when working, and put the tools and small materials in the bag. Common tools should be strapped to the body. , the required material must be passed by rope and not thrown.
1.17.2 When using a ladder to go up and down the pole, someone must hold the ladder. It is strictly forbidden to use a metal telescopic ladder. Pay attention to the surrounding environment and prevent contact with the power line. When the ladder is transferred, it is not allowed to lift (vertical) the ladder to walk.
1.18 The project management personnel of the construction unit should strengthen publicity and education to improve the safety awareness of the construction personnel, and preach to the construction personnel the life-threatening danger of electricity to personal safety. Train construction workers on safety standards and safety knowledge, improve the safety technical level and safety awareness of construction workers, and prevent serious consequences of electric shock and safety accidents. Construction personnel must carry out construction operations in strict accordance with the requirements of the "Code of Practice for Safety Production of Communication Construction Projects", and control the potential safety hazards of electric shock to a minimum. The person in charge of the construction must strictly abide by the corresponding engineering specifications, put an end to the non-standard construction in exchange for working hours, relax the engineering management, lax implementation specifications, and mere formalities, etc. The regulations stipulate the responsibility of relevant responsible persons, conduct strict assessments, and investigate responsibilities, and comprehensively promote all work safety.
