夏季高温是撒布车施工的另一大“烤”验。与冬季防冻不同，夏季施工的核心挑战在于防止设备“中暑”（高温过热）以及克服高温对物料和人员的影响。

The high temperature in summer is another major challenge for the construction of spreading vehicles. Unlike winter antifreeze, the core challenge of summer construction is to prevent equipment from "heatstroke" (overheating) and overcome the impact of high temperatures on materials and personnel.

为了保证施工效率和安全，以下是撒布车夏季施工的几大核心讲究：

In order to ensure construction efficiency and safety, the following are several core considerations for summer construction of the spreader:

一、 车辆设备的“防暑降温”

1、 Heatstroke prevention and cooling of vehicle equipment

严防发动机与液压系统高温：

Strictly prevent high temperatures in the engine and hydraulic system:

夏季气温高，车辆长时间低速重载作业，散热压力大。操作手需时刻关注仪表盘的水温和液压油温。务必定期清理发动机散热器、液压油散热器表面的灰尘和柳絮（春季遗留），保证良好的通风散热效果。如果发现水温或油温报警，必须立即停机怠速散热，严禁直接熄火，以免热量积聚损坏缸体或液压泵。

In summer, the temperature is high, and vehicles operate at low speeds and heavy loads for long periods of time, resulting in high heat dissipation pressure. The operator should always pay attention to the water temperature and hydraulic oil temperature on the dashboard. Be sure to regularly clean the dust and willow fluff (left over in spring) on the surface of the engine radiator and hydraulic oil radiator to ensure good ventilation and heat dissipation. If a water or oil temperature alarm is detected, the machine must be immediately shut down and idle for heat dissipation. It is strictly prohibited to turn off the engine directly to prevent heat accumulation and damage to the cylinder block or hydraulic pump.

检查轮胎气压：

Check tire pressure:

高温会导致轮胎内部气压升高，加上工地路面崎岖，极易引发爆胎。出车前应适当调整胎压（略低于标准值但不宜过低），并在中午高温时段注意检查轮胎温度和磨损情况。

High temperatures can cause an increase in internal tire pressure, coupled with rough road surfaces on construction sites, which can easily lead to tire blowouts. Before driving, adjust the tire pressure appropriately (slightly lower than the standard value but not too low), and pay attention to checking the tire temperature and wear during the high temperature period at noon.

电路与油路排查：

Circuit and oil circuit troubleshooting:

高温天气下，老化的电路和油路更容易引发车辆自燃。必须定期检查全车线路是否有破损、裸露，油管接口是否有渗漏。车内必须按规定配备有效的灭火器。

In hot weather, aging circuits and oil circuits are more likely to cause vehicle self ignition. It is necessary to regularly check whether the entire vehicle's wiring is damaged or exposed, and whether there is any leakage at the oil pipe interface. Effective fire extinguishers must be equipped in the car according to regulations.

二、 物料特性的精准把控

2、 Accurate control of material characteristics

粉料/水泥的防潮与板结：

Moisture prevention and compaction of powder/cement:

夏季多雨且空气湿度大，水泥、石灰等粉料极易受潮板结，导致绞龙卡死或撒布不均。

In summer, it is rainy and the air humidity is high. Cement, lime and other powders are easily affected by moisture, which can cause the auger to get stuck or spread unevenly.

装料时： 必须确保散装水泥罐车的粉料干燥，装料后要及时关闭料仓盖，防止突降阵雨。

When loading: It is necessary to ensure that the powder of the bulk cement tanker is dry, and the bin cover should be closed in a timely manner after loading to prevent sudden showers.

停工时： 如果中途休息或遇雨停工时间较长，必须将料仓内的剩余粉料排空，防止粉料在仓内吸湿结块，导致再次开工时堵料。

During shutdown: If there is a long break or rain during the shutdown, the remaining powder in the silo must be emptied to prevent the powder from absorbing moisture and clumping in the silo, which may cause blockage when resuming work.

沥青洒布车的温控：

Temperature control of asphalt distributor truck:

如果是沥青洒布车，夏季环境温度高，沥青降温速度相对较慢。这既是优势也是劣势：优势是无需过度加热；劣势是如果加热温度过高，沥青容易老化，且喷洒后冷却成型时间变长，影响后续摊铺。因此，夏季沥青加热温度应严格控制在规范下限，避免“过火”。

If it is an asphalt distributor truck, the temperature in the summer environment is high, and the cooling rate of asphalt is relatively slow. This is both an advantage and a disadvantage: the advantage is that there is no need for excessive heating; The disadvantage is that if the heating temperature is too high, the asphalt is prone to aging, and the cooling and forming time after spraying becomes longer, which affects subsequent paving. Therefore, the heating temperature of asphalt in summer should be strictly controlled at the lower limit of the specifications to avoid "overheating".

三、 人员安全与作业环境

3、 Personnel safety and working environment

严防中暑：

Prevent heatstroke:

撒布车操作手既要驾驶又要关注后方撒布情况，精神高度集中。夏季驾驶室内温度极高，必须配备空调或通风设备。建议合理安排作息，避开正午最高温时段（如12:00-14:00）进行高强度露天作业，车上常备藿香正气水、绿豆汤等防暑物资。

The operator of the spreading vehicle needs to drive while also paying attention to the spreading situation behind them, and is highly focused. The temperature inside the driver's cabin is extremely high in summer, and air conditioning or ventilation equipment must be equipped. It is recommended to arrange daily routine reasonably and avoid high-intensity outdoor work during the hottest period of noon (such as 12:00-14:00). Keep heatstroke prevention materials such as Huoxiang Zhengqi water and mung bean soup on board.

注意防滑与烫伤：

Pay attention to anti slip and scalding:

夏季多雷雨，雨后路面湿滑，撒布车自重极大，在泥泞路面作业极易发生打滑、陷车甚至侧翻。雨后复工前，务必先勘察便道和作业面承载力。此外，夏季穿着单薄，在检修发动机或清理撒布口时，要特别注意防止被高温排气管或热沥青烫伤。

In summer, there are frequent thunderstorms, and the road surface becomes wet and slippery after rain. The weight of the spreading vehicle is extremely heavy, making it prone to slipping, sinking, and even overturning when working on muddy roads. Before resuming work after rain, it is necessary to first survey the bearing capacity of the access roads and work surfaces. In addition, wearing thin clothing in summer, special attention should be paid to preventing burns from high-temperature exhaust pipes or hot asphalt when repairing the engine or cleaning the spreading port.

?四、 应对突发雷雨天气

4. Dealing with sudden thunderstorms

夏季天气多变，常有强对流天气。

The weather in summer is unpredictable, often with strong convective weather.

突遇暴雨： 必须立即停止撒布作业，关闭料仓盖和所有电气开关。如果是粉料撒布车，严禁在暴雨中继续作业，否则除尘系统失效会造成严重的扬尘污染，且物料报废。

Sudden rainstorm: the spreading operation must be stopped immediately, and the bin cover and all electrical switches must be closed. If it is a powder spreader, it is strictly prohibited to continue working in the rainstorm, otherwise the failure of the dust removal system will cause serious dust pollution, and the materials will be scrapped.

雨后复工： 必须彻底清理作业面上的积水和淤泥，并等待基层表面适度干燥（根据工艺要求）后再进行撒布，否则水膜会隔离粘结层，导致路面出现脱皮、松散等质量病害。

Resumption of work after rain: It is necessary to thoroughly clean the accumulated water and silt on the work surface, and wait for the base surface to dry moderately (according to the process requirements) before spreading. Otherwise, the water film will isolate the bonding layer, causing quality defects such as peeling and looseness on the road surface.

五、 收车后的清洁与保养

5、 Cleaning and maintenance after receiving the car

夏季高温会加速残留物料的化学反应。

The high temperature in summer will accelerate the chemical reaction of residual materials.

水泥/净浆车： 作业结束后必须第一时间彻底清洗罐体和管路。夏季水泥凝固速度极快，如果拖延清洗，残留的水泥浆会迅速硬化，导致第二天无法开工甚至损坏设备。

Cement/slurry truck: After the operation is completed, the tank and pipelines must be thoroughly cleaned as soon as possible. The setting speed of cement is extremely fast in summer. If cleaning is delayed, the residual cement slurry will quickly harden, resulting in the inability to start work the next day or even damaging equipment.

粉料车： 及时清理除尘器滤芯上的积灰，夏季潮湿空气容易导致滤芯受潮堵塞，影响除尘效果。

Powder truck: Clean the dust accumulation on the filter element of the dust collector in a timely manner. The humid air in summer can easily cause the filter element to become damp and blocked, affecting the dust removal effect.

总之，夏季撒布车施工讲究的是“人车降温、物料防潮、时刻防雷”。做好这些细节，才能确保工程在高温酷暑下依然高质量推进。

In short, the construction of summer spreading vehicles emphasizes "cooling of people and vehicles, moisture prevention of materials, and lightning protection at all times". Only by paying attention to these details can we ensure the high-quality progress of the project even in the scorching heat.
