Summer: Key Construction Points for Power Engineering Projects

I. Personal Safety Management for Heat-Related Prevention and Control

1.  Staggered construction: avoid 10:00 — 4:00 PM During periods of extreme heat, work shall be scheduled for the early morning and evening; when a red alert for high temperatures is in effect, outdoor, pole‑tower, and high‑altitude operations are suspended.

2.  Heat‑stroke prevention supplies: Ensure that the site is fully equipped with boiled and cooled water, weak salt water, and heat‑stroke remedies (such as Huoxiang Zhengqi Water and cooling oil). The consumption of plain ice water alone is strictly prohibited.

3.  Personnel management: Conduct temperature checks before each shift; reassign employees with hypertension, impaired liver function, or general physical weakness to indoor support roles; ensure continuous work periods do not exceed… 2 Hours, mandatory rotating breaks.

4.  Personal Protective Equipment: Wear breathable, insulating workwear and a sun‑protective safety helmet to prevent skin burns from prolonged sun exposure.

II. Electrical Safety During Thunderstorms and Strong Winds (Core of Power Engineering)

1.  Thunderstorm Safety Prohibition: Immediately cease pole and tower erection, conductor stringing, cable laying, high-voltage testing, and lifting operations; evacuate personnel from outdoor elevated locations; and keep clear of utility poles, guy wires, and metal structures.

2.  Temporary Power Management: Install rainproof covers and grounding/lightning‑protection devices on distribution boxes at the construction site; after rainfall, inspect cable sheaths for water ingress or damage, and conduct daily tests of residual current devices (RCDs).

3.  Excavation and trench protection: During the summer, heavy rainfall can lead to water accumulation that softens slopes. Promptly pump out standing water and reinforce shoring to prevent collapses; cable trenches and foundation pits must never be concreted while wet.

III. Key Points for Temperature Control in Civil Engineering and Foundation Construction

1.  Concrete construction: High temperatures can cause rapid initial setting; prioritize the use of retarding admixtures. Avoid pouring during midday, implement timely moisture‑retaining curing, and cover with geotextile while sprinkling water to reduce temperature and prevent cracking.

2.  Reinforcement corrosion protection: When reinforcing steel is stored outdoors, elevate it and cover it with a waterproof tarp to prevent rain exposure and rust; after high‑temperature welding, allow the components to cool completely before transporting them.

3.  Asphalt and waterproofing material application: These materials tend to flow under high-temperature conditions; schedule work during cooler morning or evening hours, implement strict fire‑prevention measures, and keep clear of energized equipment.

IV. Specialized Control Measures for Work at Heights and on Poles/Towers

1.  High temperatures and high altitudes increase the risk of heatstroke and dizziness; increase the number of supervisors and shorten the duration of each pole-climbing operation. The surfaces of poles and towers become scorching under direct sunlight; equip workers with heat-insulating, non-slip gloves.

2.  After rain, the pole surface becomes slippery. Before climbing, inspect the anti-slip foot grips and safety harness, and verify that the foundation has not been loosened by rainwater erosion.

V. Summer Protection for Equipment and Materials

1.  Power cables: Avoid exposing cable reels to direct sunlight; high temperatures accelerate the aging of the insulation. Cool the cables before installation to prevent the outer sheath from softening, becoming damaged, and causing electrical leakage.

2.  Electrical equipment: Transformers, switchgear, and instruments shall be stored in a cool, well-ventilated area; outdoor temporary distribution equipment must be sheltered from the sun and protected from rain to prevent overheating and tripping.

3.  Flammable and explosive consumables (paints, thinners) shall be stored separately in a cool, well-ventilated warehouse, and hot work on site shall be strictly controlled.

VI. Fire Safety Management

1.  High temperatures and dry conditions make materials highly flammable; smoking is strictly prohibited in the work area, and fire extinguishers and fire buckets must be fully equipped. Cable heat-shrink and welding operations must be supervised by designated personnel, and upon completion, ensure that no embers remain.

2.  Regularly inspect the cooling system and tires of transport vehicles and construction machinery to prevent overheating, spontaneous combustion, and tire blowouts.

VII. On-Site Logistics and Emergency Response

1.  Set up temporary shaded rest shelters to ensure adequate ventilation; prohibit unauthorized wiring and the use of high-power appliances in dormitories to prevent heatstroke and fires.

2.  Develop emergency response plans for heatstroke first aid, lightning‑related injuries, excavation pit collapses, and electrical shock incidents, and conduct pre‑shift briefings and training for all personnel.
