1. Including commonly used cable laying below 10kV, not considering cable laying in rivers and water areas, underwater, underground and other conditions.
2. When cables are directly buried in mountainous and hilly areas, the fixed working days are multiplied by a coefficient of 1.3. The materials required in this area, such as fixed piles, clamps, etc., are calculated based on actual conditions.
3. The additional length of the waveform and the reserved length are not taken into account in the cable laying setting amount. This length should be included in the engineering quantity. 4. This division does not include the following work contents: (1) Production and installation of thermal insulation layer and protective layer. (2) Winter construction heating work of cables.
5. The fixed man-days and machinery for the production and installation of copper core cable heads are multiplied by a factor of 1.2. 8. Lighting equipment installation project:
1. Mainly includes the installation of various cantilever lights, square lights, high pole lights, garden lights and lighting components. 2. The wiring of various lamp stand components and appliances have been comprehensively considered within the quota and will not be adjusted during use. 3. All lamp posts must be wired with corresponding piping and wiring quotas.
4. The factor of high-altitude operations within 10m has been taken into account. If the installation height exceeds 10m, the labor quota shall be multiplied by a factor of 1.4. 5. Includes the use of instruments to measure insulation and test lighting of general lamps.
6. Does not include the production of cable joints and the soldering and crimping of wire terminals. If actually used, the quota of the relevant segment can be applied.
7. The reserved wires for switches, sockets, buttons, etc. have been integrated into the corresponding quotas and are not calculated separately. 9. Lightning protection and grounding device engineering:
1. Suitable for lightning protection and grounding of high-pole light poles, power transformation and distribution system grounding and lightning rod grounding devices.
2. The setting amount of grounding busbar laying is based on the natural floor and general soil quality, including the excavation, filling and compaction of trenches. The amount of earthwork should not be calculated when implementing the quota in this section. If there are stones, slag, water, obstacles, etc., additional calculations may be made.
3. It does not apply to the laying of grounding wires and the installation of grounding electrodes using blasting methods, nor does it include testing of grounding devices and grounding resistance using soil replacement or chemical treatment in areas with high soil resistivity.
4. The installation of lightning rods and lightning protection down conductors have taken into consideration the factors of high-altitude operations. 5. Lightning rods are considered as finished parts.
