冷再生機(jī)租賃服務(wù)在各類路基處理工程中展現(xiàn)出顯著的適應(yīng)性，尤其在低填淺挖、素填土路段及特殊地形（如等場景中，能有效配合路基處理工藝，提升施工效率與質(zhì)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.

　　在低填淺挖路段的處理中，冷再生機(jī)可發(fā)揮重要作用。當(dāng)?shù)缆费鼐€遇到填方高度小于 1.5m 的低填路段或挖方高度小于 0.8m 的淺挖路段，需對路槽以下 0.8m 范圍內(nèi)進(jìn)行 4% 生石灰土換填時，冷再生機(jī)能夠現(xiàn)場對原地面材料與生石灰進(jìn)行拌合。其強(qiáng)大的破碎和攪拌功能可將原有土體與添加的生石灰充分混合，確保配比均勻，減少材料運(yùn)輸與堆放環(huán)節(jié)，降低施工成本。同時，拌合后的混合料能快速達(dá)到非常佳含水量和壓實(shí)度要求，為后續(xù)路面結(jié)構(gòu)施工奠定堅(jiān)實(shí)基礎(chǔ)，尤其適用于地形起伏較小、施工范圍集中的路段。

　　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.

　　面對素填土路段，冷再生機(jī)的租賃使用可靈活應(yīng)對不同厚度的素填土處理需求。當(dāng)素填土厚度≤0.8m 時，清除素填土后需回填合格路基填料，此時冷再生機(jī)可用于對回填材料進(jìn)行現(xiàn)場拌合與平整，保證填料均勻性；若素填土厚度在 0.8m 至 3.5m 之間，需清除耕植土并翻挖原裝素填土摻 6% 生石灰回填壓實(shí)時，冷再生機(jī)的優(yōu)勢更為突出。它能直接深入素填土內(nèi)部，將土體破碎后與生石灰合理混合，避免傳統(tǒng)施工中因人工拌合不均導(dǎo)致的質(zhì)量問題，同時縮短翻挖與回填的間隔時間，加快施工進(jìn)度，適應(yīng)素填土結(jié)構(gòu)疏散、需快速穩(wěn)定的處理要求。

　　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.

　　在水塘路段的路基處理中，冷再生機(jī)可配合其他工藝提升處理效果。當(dāng)水塘需廢棄按干塘處理時，在清除淤泥并換填毛渣石、素土至路床頂后，若素土回填層需要改良，冷再生機(jī)可對素土進(jìn)行現(xiàn)場拌合加固，增強(qiáng)其整體性；對于保留水塘的情況，在路基內(nèi)側(cè)清淤并分層回填毛渣石至塘埂后，若塘埂周邊的素土需處理以減少沉降，冷再生機(jī)可對塘埂附近的土體進(jìn)行攪拌處理，配合臺階開挖與土工格柵鋪設(shè)，提升塘埂處路基的穩(wěn)定性。此外，在處理塘埂高差大、坡度陡的問題時，冷再生機(jī)能夠靈活調(diào)整作業(yè)角度，對臺階處的回填土進(jìn)行充分拌合，確保每層填土的密實(shí)度，配合雙向土工格柵的鋪設(shè)，有效避免不均勻沉降。

　　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.

　　在路基橫斷面勘察設(shè)計(jì)的相關(guān)要求中，冷再生機(jī)的租賃使用也能提供支持。例如，在上下行分臺高控制在 5~6 米的路段，冷再生機(jī)可適應(yīng)不同臺段的施工高度，靈活調(diào)整拌合深度；對于中分帶采用輕型支擋結(jié)構(gòu)的路段，冷再生機(jī)在處理周邊土體時可合理控制拌合范圍，避免對支擋結(jié)構(gòu)造成干擾。同時，在加強(qiáng)上下臺間排水的施工中，冷再生機(jī)處理后的土體透水性更易控制，可配合排水設(shè)施提升排水效率，保障路基穩(wěn)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.
