冷再生机作为道路养护领域的 “绿色利器”，凭借现场修复、旧料再利用等优势，大幅降低施工对环境的影响。然而，这并不意味着它能 “随心所欲” 作业。从场地条件到气候因素，从周边生态到施工规范，冷再生机租赁的实际应用，需要与环境达成微妙的 “默契”。

　　As a "green weapon" in the field of road maintenance, the cold recycling machine greatly reduces the impact of construction on the environment by virtue of its advantages such as on-site repair and reuse of old materials. However, this does not mean that it can do homework "as it pleases". From site conditions to climate factors, from surrounding ecology to construction standards, the practical application of cold recycling machine leasing requires a subtle "tacit understanding" with the environment.

　　一、场地基础：稳定作业的 “先天条件”

　　1、 Site foundation: the "innate condition" for stable operation

　　冷再生机的正常运行对施工场地有着硬性要求。首先，场地需具备足够的承载能力，尤其是大型履带式冷再生机，整机重量可达数十吨，松软、泥泞的地面会导致设备下陷，影响铣刨与拌合精度，甚至造成机械损坏。因此，施工前需对场地进行压实处理，必要时铺设碎石或钢板作为临时路基。其次，作业空间要充足，冷再生机在铣刨、运输、摊铺等环节需要回转、进退空间，狭窄的街巷或周边障碍物过多的区域，可能限制设备操作，增加施工难度与安全风险。此外，场地内的水电供应也需稳定，虽然冷再生机自带动力系统，但拌合环节需要大量用水，且夜间施工可能涉及照明用电，提前规划好水电接入点至关重要。

　　The normal operation of the cold recycling machine has strict requirements for the construction site. Firstly, the site needs to have sufficient load-bearing capacity, especially for large tracked cold recycling machines, which can weigh tens of tons. Soft and muddy ground can cause equipment to sink, affecting milling and mixing accuracy, and even causing mechanical damage. Therefore, the site needs to be compacted before construction, and if necessary, crushed stones or steel plates should be laid as temporary roadbeds. Secondly, the workspace should be sufficient. The cold recycling machine needs to have space for rotation, advance and retreat during milling, transportation, paving and other processes. Narrow streets or areas with too many obstacles may limit equipment operation, increase construction difficulty and safety risks. In addition, the water and electricity supply within the site also needs to be stable. Although the cold recycling machine has its own power system, the mixing process requires a large amount of water, and nighttime construction may involve lighting electricity. It is crucial to plan the water and electricity access points in advance.

　　二、气候因素：与天气的 “时间博弈”

　　2、 Climate factors: the 'time game' with weather

　　冷再生机的施工效果与气候条件紧密相关。雨天是冷再生作业的 “大敌”，雨水会稀释再生剂，降低新旧材料的粘结强度，导致再生层压实度不足，后期易出现松散、坑洼等病害。因此，在租赁冷再生机前，需密切关注天气预报，避免在降雨前后 48 小时内施工；若遇突发降雨，需立即停止作业，覆盖未压实的再生层，防止雨水渗透。低温环境同样影响施工质量，当气温低于 5℃时，再生剂与沥青的活性降低，混合料难以压实成型，此时需采取加热措施（如预热旧料、添加温拌剂），或暂停施工。相比之下，晴朗、微风的天气最适宜冷再生作业，既能保证材料干燥，又利于减少粉尘扩散。

　　The construction effect of the cold recycling machine is closely related to the climatic conditions. Rainy days are the "enemy" of cold recycling operations. Rainwater dilutes the regeneration agent, reduces the bonding strength between new and old materials, and leads to insufficient compaction of the regeneration layer, which can easily cause diseases such as looseness and potholes in the later stage. Therefore, before renting a cold recycling machine, it is necessary to closely monitor the weather forecast and avoid construction within 48 hours before and after rainfall; In case of sudden rainfall, the operation should be stopped immediately and the uncompacted regeneration layer should be covered to prevent rainwater infiltration. Low temperature environment also affects construction quality. When the temperature is below 5 ℃, the activity of the rejuvenator and asphalt decreases, and the mixture is difficult to compact and form. At this time, heating measures (such as preheating old materials, adding warm mix agents) or suspending construction are needed. In contrast, clear and gentle weather is most suitable for cold recycling operations, which can ensure material dryness and reduce dust dispersion.

　　三、生态保护：绿色施工的 “底线约束”

　　3、 Ecological Protection: The 'Bottom Line Constraint' of Green Construction

　　冷再生机虽以环保著称，但施工过程仍需严守生态保护红线。首先是粉尘控制，铣刨旧路面时会产生大量扬尘，若不加以处理，不仅污染空气，还可能影响周边居民健康。因此，设备需配备高效的除尘装置，如雾炮机、吸尘管道，实时抑制粉尘；运输车辆需封闭严密，避免遗撒造成二次扬尘。其次，施工产生的废水（如清洗设备、拌合剩余的污水）含有沥青、再生剂等污染物，不可直接排放，需设置沉淀池进行过滤处理，达标后方可排放或循环利用。此外，冷再生机运行时会产生噪音，在居民区、学校周边施工时，需严格遵守当地噪音管控规定，避开居民休息时间，或采取加装隔音屏障等降噪措施。

　　Although the cold recycling machine is known for its environmental friendliness, the construction process still needs to strictly adhere to the ecological protection red line. Firstly, dust control is important. When milling and planing old road surfaces, a large amount of dust is generated. If not treated properly, it not only pollutes the air but may also affect the health of surrounding residents. Therefore, the equipment needs to be equipped with efficient dust removal devices, such as fog cannons and suction pipes, to suppress dust in real time; Transport vehicles need to be tightly sealed to avoid secondary dust caused by scattering. Secondly, the wastewater generated during construction (such as cleaning equipment and residual mixing wastewater) contains pollutants such as asphalt and rejuvenators, which cannot be directly discharged. A sedimentation tank needs to be set up for filtration treatment, and can only be discharged or recycled after meeting the standards. In addition, the operation of the cold regeneration machine will generate noise. When constructing in residential areas or around schools, it is necessary to strictly comply with local noise control regulations, avoid residents' rest time, or take noise reduction measures such as installing sound barriers.

　　四、周边环境：与社区的 “和谐共处”

　　4、 Surrounding environment: harmonious coexistence with the community

　　冷再生机施工还需兼顾周边社区的生产生活需求。在城市主干道、商业区等交通繁忙区域作业时，需合理规划施工时段与交通疏导方案，避免因长时间封路造成交通拥堵；可采用半幅施工、夜间施工等方式，减少对交通的影响。若周边有医院、精密仪器工厂等对振动敏感的场所，需评估冷再生机作业产生的振动是否会造成干扰，必要时调整施工工艺或更换低振动设备。此外，施工前需与周边居民、商户充分沟通，公示施工计划与环保措施，争取理解与支持，避免因环境问题引发纠纷。

　　The construction of cold recycling machines also needs to take into account the production and living needs of surrounding communities. When working in busy traffic areas such as urban main roads and commercial districts, it is necessary to plan the construction period and traffic diversion plan reasonably to avoid traffic congestion caused by long-term road closures; Half width construction, nighttime construction, and other methods can be used to reduce the impact on traffic. If there are hospitals, precision instrument factories and other places sensitive to vibration in the surrounding area, it is necessary to evaluate whether the vibration generated by the cold regeneration machine operation will cause interference, and adjust the construction process or replace low vibration equipment if necessary. In addition, it is necessary to fully communicate with surrounding residents and merchants before construction, publicize the construction plan and environmental protection measures, strive for understanding and support, and avoid disputes caused by environmental issues.
