冷再生机租赁服务在各类路基处理工程中展现出显著的适应性，尤其在低填浅挖、素填土路段及特殊地形（如等场景中，能有效配合路基处理工艺，提升施工效率与质量。

　　The leasing service of cold recycling machines has shown significant adaptability in various roadbed treatment projects, especially in low fill and shallow excavation, plain fill road sections, and special terrains (such as), which can effectively cooperate with roadbed treatment processes, improve construction efficiency and quality.

　　在低填浅挖路段的处理中，冷再生机可发挥重要作用。当道路沿线遇到填方高度小于 1.5m 的低填路段或挖方高度小于 0.8m 的浅挖路段，需对路槽以下 0.8m 范围内进行 4% 生石灰土换填时，冷再生机能够现场对原地面材料与生石灰进行拌合。其强大的破碎和搅拌功能可将原有土体与添加的生石灰充分混合，确保配比均匀，减少材料运输与堆放环节，降低施工成本。同时，拌合后的混合料能快速达到含水量和压实度要求，为后续路面结构施工奠定坚实基础，尤其适用于地形起伏较小、施工范围集中的路段。

　　In the treatment of low fill and shallow excavation sections, cold recycling machines can play an important role. When encountering low fill sections with a filling height of less than 1.5m or shallow excavation sections with an excavation height of less than 0.8m along the road, it is necessary to replace the area 0.8m below the road trench with 4% quicklime soil. The cold recycling machine can mix the raw ground materials with quicklime on site. Its powerful crushing and mixing functions can fully mix the original soil with the added quicklime, ensuring uniform proportioning, reducing material transportation and stacking links, and lowering construction costs. At the same time, the mixed material can quickly reach the optimal moisture content and compaction requirements, laying a solid foundation for subsequent pavement structure construction, especially suitable for road sections with small terrain undulations and concentrated construction areas.

　　面对素填土路段，冷再生机的租赁使用可灵活应对不同厚度的素填土处理需求。当素填土厚度≤0.8m 时，素填土后需回填合格路基填料，此时冷再生机可用于对回填材料进行现场拌合与平整，保证填料均匀性；若素填土厚度在 0.8m 3.5m 之间，需耕植土并翻挖原装素填土掺 6% 生石灰回填压实时，冷再生机的优势更为突出。它能直接深入素填土内部，将土体破碎后与生石灰精准混合，避免传统施工中因人工拌合不均导致的质量问题，同时缩短翻挖与回填的间隔时间，加快施工进度，适应素填土结构疏散、需快速稳定的处理要求。

　　In the face of bare soil road sections, the leasing and use of cold recycling machines can flexibly meet the treatment needs of different thicknesses of bare soil. When the thickness of the plain fill soil is ≤ 0.8m, qualified roadbed filling material needs to be backfilled after removing the plain fill soil. At this time, the cold recycling machine can be used for on-site mixing and leveling of the backfill material to ensure the uniformity of the filling material; If the thickness of the plain fill soil is between 0.8m and 3.5m, it is necessary to remove the cultivated soil and excavate the original plain fill soil mixed with 6% quicklime for backfilling and pressing. The advantages of the cold recycling machine are more prominent. It can directly penetrate into the interior of plain fill soil, crush the soil and mix it accurately with quicklime, avoiding quality problems caused by uneven manual mixing in traditional construction. At the same time, it shortens the interval between excavation and backfilling, accelerates construction progress, and adapts to the requirements of dispersing plain fill soil structures and requiring rapid and stable processing.

　　在水塘路段的路基处理中，冷再生机可配合其他工艺提升处理效果。当水塘需废弃按干塘处理时，在淤泥并换填毛渣石、素土路床顶后，若素土回填层需要改良，冷再生机可对素土进行现场拌合加固，增强其整体性；对于保留水塘的情况，在路基内侧清淤并分层回填毛渣石塘埂后，若塘埂周边的素土需处理以减少沉降，冷再生机可对塘埂附近的土体进行搅拌处理，配合台阶开挖与土工格栅铺设，提升塘埂处路基的稳定性。此外，在处理塘埂高差大、坡度陡的问题时，冷再生机能够灵活调整作业角度，对台阶处的回填土进行充分拌合，确保每层填土的密实度，配合双向土工格栅的铺设，有效避免不均匀沉降。

　　In the roadbed treatment of the pond section, the cold recycling machine can be combined with other processes to improve the treatment effect. When the pond needs to be abandoned and treated as a dry pond, after removing the silt and replacing it with rubble and plain soil to the top of the roadbed, if the plain soil backfill layer needs to be improved, the cold recycling machine can carry out on-site mixing and reinforcement of the plain soil to enhance its integrity; For the case of retaining the pond, after dredging the inner side of the roadbed and backfilling the debris stone layer by layer to the pond ridge, if the surrounding soil of the pond ridge needs to be treated to reduce settlement, the cold recycling machine can mix the soil near the pond ridge, and cooperate with step excavation and geogrid laying to improve the stability of the roadbed at the pond ridge. In addition, when dealing with the problems of large height differences and steep slopes in pond embankments, the cold recycling machine can flexibly adjust the operating angle, fully mix the backfill soil at the steps, ensure the compactness of each layer of soil, and cooperate with the laying of two-way geogrids to effectively avoid uneven settlement.

　　在路基横断面勘察设计的相关要求中，冷再生机的租赁使用也能提供支持。例如，在上下行分台高控制在 5~6 米的路段，冷再生机可适应不同台段的施工高度，灵活调整拌合深度；对于中分带采用轻型支挡结构的路段，冷再生机在处理周边土体时可精准控制拌合范围，避免对支挡结构造成干扰。同时，在加强上下台间排水的施工中，冷再生机处理后的土体透水性更易控制，可配合排水设施提升排水效率，保障路基稳定。

　　In the relevant requirements for the survey and design of roadbed cross-sections, the leasing and use of cold recycling machines can also provide support. For example, in sections where the height of the upper and lower platforms is controlled at 5-6 meters, the cold recycling machine can adapt to the construction height of different platforms and flexibly adjust the mixing depth; For road sections with lightweight support structures in the median strip, the cold recycling machine can accurately control the mixing range when processing the surrounding soil, avoiding interference with the support structure. At the same time, in the construction of strengthening the drainage between the upper and lower stages, the permeability of the soil treated by the cold recycling machine is easier to control, which can be combined with drainage facilities to improve drainage efficiency and ensure the stability of the roadbed.
