在道路养护与改造工程中，冷再生机因其、经济的特点，已成为处理旧路面材料的设备。为确保施工质量与效率，必须严格按照规范流程操作，下面将详细说明使用冷再生机的具体方法。

In road maintenance and renovation projects, cold recycling machines have become the preferred equipment for processing old pavement materials due to their high efficiency, energy saving, environmental protection, and economic characteristics. To ensure construction quality and efficiency, it is necessary to strictly follow the standardized procedures. The specific methods of using cold regeneration technology will be explained in detail below.

施工前的准备工作关重要，要对作业路段进行细致的勘察。技术人员需要准确评估道路损坏程度，仔细检查基层结构状况，并确认地下管线分布位置。针对基层存在严重病害的路段，如出现大面积坑槽或松散现象，必须预先制定专项处理方案。同时要根据道路实际尺寸和工期要求，科学规划设备行进路线和工作区域，避免出现重复施工或遗漏作业的情况。

The preparation work before construction is crucial, and the first step is to conduct a comprehensive and detailed survey of the work section. Technicians need to accurately assess the extent of road damage, carefully inspect the condition of the underlying structure, and confirm the distribution of underground pipelines. For road sections with serious diseases at the grassroots level, if there are large areas of potholes or looseness, a special treatment plan must be formulated in advance. At the same time, it is necessary to scientifically plan the equipment travel route and work area according to the actual size of the road and the requirements of the construction period, in order to avoid repeated construction or missed operations.

设备检查环节需要关注机械部件的运行状态。操作人员应当仔细检查发动机各项油液是否充足，查看传动皮带松紧度是否合适，确认液压系统管路连接牢固无泄漏。特别要注意检查转子刀具的磨损情况，磨损严重的刀具必须立即更换。电气系统方面，要确保所有线路完好无损，各类仪表指示灯工作正常。设备调试时需进行空载试运行，调整转子转速和喷洒系统参数，确保其符合施工技术要求。

The equipment inspection process needs to focus on the operational status of mechanical components. The operator should carefully check whether the engine's various fluids are sufficient, check whether the tightness of the transmission belt is appropriate, and confirm that the hydraulic system pipeline connections are firm and leak free. Special attention should be paid to checking the wear of the rotor cutting tools, and tools with severe wear must be replaced immediately. In terms of electrical system, it is necessary to ensure that all circuits are intact and all instrument indicators are working properly. During equipment debugging, it is necessary to conduct a no-load trial run, adjust the rotor speed and spray system parameters to ensure that they meet the construction technical requirements.

材料准备工作同样不可忽视，必须根据设计要求准备足量的乳化沥青、水泥等添加剂。所有材料都要经过严格的质量检测，确保各项指标符合标准规范。同时要对回收的旧料进行级配分析和含水量测试，为后续的配合比设计提供准确依据。

Material preparation work cannot be ignored, and sufficient amounts of emulsified asphalt, cement and other additives must be prepared according to design requirements. All materials must undergo strict quality testing to ensure that all indicators meet the standard specifications. At the same time, grading analysis and moisture content testing should be conducted on the recycled old materials to provide accurate basis for subsequent mix design.

施工作业过程中，要将冷再生机准确就位。操作人员需要调整设备位置，使转子中心线与道路中心线完全对齐，并通过支腿调平设备。参数设置方面，要根据路面材料硬度合理确定转子转速，通常控制在3-6米/分钟的行进速度较为适宜。拌和深度必须严格按照设计要求控制，确保旧料与添加剂充分混合又不损伤路基。添加剂喷洒系统要保持稳定运行，确保按比例均匀喷洒。

During the construction process, the first step is to accurately position the cold recycling machine. The operator needs to adjust the position of the equipment to align the rotor centerline completely with the road centerline, and level the equipment with the support legs. In terms of parameter settings, the rotor speed should be reasonably determined based on the hardness of the road surface material, usually controlled at a suitable travel speed of 3-6 meters per minute. The mixing depth must be strictly controlled according to the design requirements to ensure that the old materials and additives are fully mixed without damaging the roadbed. The additive spraying system should maintain stable operation to ensure even and proportional spraying.

实际操作时，要先启动转子达到设定转速，再缓慢推进设备。作业过程中要持续监控发动机转速、液压压力等关键参数，同时观察混合料的均匀程度。完成拌和后要及时进行摊铺压实作业，采用先轻后重的碾压方式，确保路面达到设计要求的平整度和密实度。

In actual operation, the rotor should be started first to reach the set speed, and then the equipment should be slowly advanced. During the homework process, it is necessary to continuously monitor key parameters such as engine speed and hydraulic pressure, while observing the uniformity of the mixture. After completing the mixing, timely paving and compaction operations should be carried out, using a light to heavy rolling method to ensure that the road surface meets the design requirements for smoothness and compactness.

施工结束后的维护工作同样重要。要彻底清洗设备各部件，特别是转子和喷洒系统。完成清洗后要对所有润滑点加注润滑油，检查紧固件状态。质量检测环节需要使用仪器测量路面压实度和平整度，发现问题要及时处理。要清理施工现场，修复受损的附属设施，确保道路恢复正常使用。

The maintenance work after the completion of construction is equally important. Firstly, it is necessary to thoroughly clean all components of the equipment, especially the rotor and spray system. After cleaning, add lubricating oil to all lubrication points and check the status of fasteners. The quality inspection process requires the use of professional instruments to measure the compaction and flatness of the road surface, and any problems found should be dealt with in a timely manner. Finally, it is necessary to clean up the construction site, repair damaged ancillary facilities, and ensure that the road is restored to normal use.

通过规范化的操作流程和细致的维护保养，不仅能保证施工质量，还能显著延长设备使用寿命。如需了解更详细的故障排查方法或特殊工况下的操作技巧，欢迎随时咨询技术人员。

Through standardized operating procedures and meticulous maintenance, not only can construction quality be guaranteed, but the service life of equipment can also be significantly extended.
