​High-Temperature Warning: Smart Tips for Construction Site Operations – Check Them Out Now

High-Temperature Construction Precautions for Concrete  

1. Before concrete pouring, fully water and moisten the formwork, and ensure no standing water remains on the formwork surface.   2. Avoid concrete pouring during peak daytime high temperatures; instead, conduct pouring after 3 PM or at night.   3. When preparing concrete, add an appropriate amount of retarder to extend its initial setting time.   4. During concrete transportation and pouring, prevent excessive water evaporation by taking proper covering measures. Control both the concrete slump and its temperature when entering the formwork.   5. After concrete sets, cover exposed parts with plastic film to maintain moisture; after form removal, continue covering the concrete surface for curing.   6. Implement independent heat dissipation measures for mass concrete to ensure the internal temperature difference meets code requirements.  

High-Temperature Construction Precautions for Masonry  

1. Bricks for wall construction should be fully watered and moistened 1–2 days in advance, and immersed in a dedicated pool before masonry work. Set a proper backwater slope on-site to ensure no standing water or debris accumulates in the masonry.   2. Masonry mortar must be used immediately after mixing, and its workability should meet requirements. When the temperature exceeds 30°C, cement mortar must be used within 2 hours and discarded if not used within this period.   3. Adopt the "one brick with one trowel of mortar" method for wall construction. Minimize the mortar spreading distance to prevent mortar from hardening due to water evaporation caused by overly long spreading lengths.   4. Plastering work must be conducted no less than 30 days after the completion of the masonry structure.  

High-Temperature Construction Precautions for Installation Works  

1. Ensure sunshade or ventilation measures are in place at the work site, and avoid construction during high-temperature periods such as noon.   2. Consider the impact of temperature during welding operations. All types of gas cylinders must not be placed in high-temperature environments or under direct sunlight.   3. Avoid using instruments such as levels and total stations during high-temperature periods to prevent inaccurate observation data.   4. High temperatures accelerate wire aging. Regularly inspect and replace aged wires, and adjust wires exposed to high temperatures to prevent fires.   In high-temperature conditions, it is essential to not only implement engineering technical measures but also pay attention to relevant management measures.  

Construction Organization  

1. Ensure construction personnel have adequate rest time. Avoid construction during high-temperature periods as much as possible, and make up for lost time by arranging night shifts if necessary. 2. Adequately supply heatstroke prevention items on-site, such as tea, mung bean soup, and cooling oil. Strengthen food hygiene and safety management to prevent food spoilage due to high temperatures.   3. Implement effective ventilation, heat insulation, and cooling measures in high-temperature work areas. Promptly reassign construction personnel who do not meet physical requirements for high-temperature work to other positions.  Rainproof and Flood Control  1. Timely obtain meteorological and hydrological data, and reasonably arrange the construction schedule for the rainy season.   2. Build temporary drainage ditches in construction sections affected by the rainy season. Backfilling work must be carried out on rain-free days.   3. Avoid outdoor concrete construction on rainy days as much as possible; cover and protect concrete that has already been poured.   4. Inspect and reinforce supports, scaffolding, and similar structures promptly after wind and rain.   5. Store on-site materials properly: elevate the lower parts with pads and cover the upper parts with protective materials. Prepare flood control supplies such as straw bags.  

Lightning and Electricity Protection   1. Ensure proper lightning protection grounding for tall machinery or supports. Implement protective zero connection for construction machinery and lighting equipment. Strictly prohibit staying under power lines.   2. Inspect power lines to prevent electric leakage or fires caused by accelerated wire aging due to high temperatures.   3. Self-provided generator sets must be interlocked with the external power supply. Install switching devices or main distribution boxes, and strictly prohibit parallel operation of generators with the external power grid.
