在道路施工領域，冷再生機租賃業務日益紅火，但其在低溫環境與凍土、巖層等特殊地質條件下作業時，常面臨諸多挑戰。深刻了解設備低溫啟動限制，掌握應對特殊地質的有效方法，是租賃方與施工方順利推進工程、保障設備運行的關鍵。

　　In the field of road construction, the leasing business of cold recycling machines is becoming increasingly popular, but they often face many challenges when operating in low-temperature environments and special geological conditions such as frozen soil and rock layers. A deep understanding of the low-temperature start-up limitations of equipment and effective methods for dealing with special geological conditions are key to the smooth progress of the project and the efficient operation of the equipment by both the lessee and the construction party.

　　一、掌握低溫啟動限制，為設備 “解凍” 賦能

　　1、 Master the low-temperature start limit and empower the device to 'thaw'

　　低溫環境是冷再生機租賃面臨的首要難題。當氣溫驟降，冷再生機的液壓油會變得黏稠，流動性大幅降低，導致液壓系統壓力傳導遲緩，設備啟動后動作僵硬，難以正常進行銑刨、拌和等作業。發動機也會因低溫受到影響，機油黏度增加使內部摩擦阻力增大，啟動時需要消耗更多能量，若強行啟動，可能加劇活塞、曲軸等部件的磨損；柴油在低溫下易產生結蠟現象，堵塞油路，使發動機無法獲得充足燃料供應，甚熄火。此外，電瓶在低溫下的放電能力減弱，冷啟動電流不足，可能導致設備無法正常點火。

　　Low temperature environment is the primary challenge faced by cold recycling machine leasing. When the temperature drops sharply, the hydraulic oil of the cold regeneration machine will become viscous and the fluidity will be greatly reduced, resulting in slow pressure transmission in the hydraulic system, stiff action after equipment startup, and difficulty in normal milling, mixing and other operations. The engine can also be affected by low temperatures, causing an increase in oil viscosity and internal friction resistance. It requires more energy to start, and if forced to start, it may exacerbate wear on components such as pistons and crankshafts; Diesel fuel is prone to wax formation at low temperatures, which can clog the fuel system and prevent the engine from receiving sufficient fuel supply, and even stall. In addition, the discharge capacity of the battery is weakened at low temperatures, and the cold start current is insufficient, which may cause the equipment to fail to ignite properly.

　　針對這些問題，租賃方在設備交付前需做好準備。提前更換適合低溫環境的液壓油、機油和柴油，選擇低溫流動性好的油品，如低凝點的液壓油和添加抗凝劑的柴油；為設備加裝保溫裝置，如使用保溫棉包裹發動機艙、液壓油箱等關鍵部位，減少熱量散失。同時，配備預熱設備，如電加熱板、冷卻液預熱器，在啟動前對設備進行預熱，使液壓油和發動機達到合適的工作溫度，降低啟動阻力。對于長期在低溫環境作業的租賃設備，還需定期檢查電瓶狀態，及時充電或更換老化電瓶，確保啟動電力充足。

　　In response to these issues, the lessee needs to make comprehensive preparations before delivering the equipment. Replace hydraulic oil, engine oil, and diesel suitable for low-temperature environments in advance, and choose oil with good low-temperature fluidity, such as hydraulic oil with low pour point and diesel with added anticoagulant; Install insulation devices for equipment, such as wrapping key parts such as the engine compartment and hydraulic oil tank with insulation cotton, to reduce heat loss. At the same time, preheating equipment such as electric heating plates and coolant preheaters are equipped to preheat the equipment before starting, so that the hydraulic oil and engine reach the appropriate working temperature and reduce starting resistance. For rental equipment that operates in low-temperature environments for a long time, it is necessary to regularly check the battery status, charge or replace aging batteries in a timely manner, and ensure sufficient starting power.

　　二、應對凍土阻礙，制定差異化施工策略

　　2、 Develop differentiated construction strategies to address permafrost obstacles

　　在凍土區域使用租賃的冷再生機施工，需充分考慮凍土的特性。凍土根據凍結時間分為季節凍土和多年凍土，其含冰量、硬度和穩定性差異顯著。對于淺層的季節凍土，可在施工前采用物理加熱的方式降低其硬度，如利用熱風機、地熱輻射等方法融化表層凍土，使冷再生機能夠順利銑刨；也可使用大功率的破碎設備對凍土進行預處理，將其破碎成小塊后，再由冷再生機進行拌和作業。

　　When using leased cold recycling machines for construction in frozen soil areas, it is necessary to fully consider the characteristics of frozen soil. Frozen soil is divided into seasonal frozen soil and perennial frozen soil based on freezing time, with significant differences in ice content, hardness, and stability. For shallow seasonal frozen soil, physical heating can be used to reduce its hardness before construction, such as using hot air blowers, geothermal radiation, and other methods to melt the surface frozen soil, so that the cold recycling machine can smoothly mill it; High power crushing equipment can also be used to pre treat frozen soil, breaking it into small pieces and then mixing it with a cold recycling machine.

　　面對多年凍土，施工時要避免對其天然凍結狀態造成過度破壞，防止出現融沉現象?？刹捎梅侄问┕?、快速作業的方式，減少設備在同一區域的停留時間，降低熱量傳遞對凍土的影響。同時，在施工區域搭建臨時保溫棚，保持棚內低溫環境，減緩凍土融化速度。此外，根據凍土的力學特性，合理調整冷再生機的作業參數，如降低銑刨深度、減慢行進速度，避免設備因負荷過大而損壞。

　　In the face of permafrost, excessive damage to its natural frozen state should be avoided during construction to prevent thaw settlement. Segmented construction and rapid operation can be adopted to reduce the dwell time of equipment in the same area and minimize the impact of heat transfer on frozen soil. At the same time, temporary insulation sheds should be built in the construction area to maintain a low temperature environment inside the sheds and slow down the rate of permafrost melting. In addition, based on the mechanical properties of frozen soil, adjust the operating parameters of the cold recycling machine reasonably, such as reducing the milling depth and slowing down the travel speed, to avoid equipment damage due to excessive load.

　　三、破解巖層困境，巧用技術與設備組合

　　3、 Cracking the rock formation dilemma by skillfully combining technology and equipment

　　巖層地質堅硬，普通的冷再生機難以直接進行銑刨作業。此時，需根據巖層的硬度和結構，采用多種技術手段配合施工。對于硬度較低的頁巖、砂巖等巖層，可在冷再生機上加裝液壓破碎錘，利用破碎錘的高頻沖擊力將巖層擊碎，再由冷再生機進行后續的銑刨、拌和；也可先用鉆機在巖層上鉆出密集的小孔，削弱巖層的整體性，降低冷再生機的作業難度。

　　The geological strata are hard, and ordinary cold recycling machines are difficult to directly carry out milling operations. At this point, multiple technical methods need to be used to coordinate construction based on the hardness and structure of the rock layers. For rock formations such as shale and sandstone with low hardness, hydraulic breakers can be installed on the cold recycling machine to use the high-frequency impact force of the breakers to crush the rock formations, and then the cold recycling machine can perform subsequent milling and mixing; Alternatively, a drilling rig can be used to drill dense small holes in the rock formation, weakening the integrity of the rock formation and reducing the difficulty of the cold recycling machine's operation.

　　針對花崗巖、玄武巖等硬度較高的巖層，則需采用爆破與冷再生機協同作業的方式。先由的爆破團隊進行鉆孔爆破，將巖層破碎成合適的塊度，然后由冷再生機對爆破后的石料進行銑刨、破碎和拌和，制成再生混合料。在整個過程中，要嚴格控制爆破的范圍和強度，確保冷再生機的；同時，根據爆破后的石料粒徑，調整冷再生機的刀具間距和轉速，保證再生效果。

　　For rock layers with high hardness such as granite and basalt, it is necessary to use a coordinated approach of blasting and cold regeneration. Firstly, a professional blasting team conducts drilling and blasting to break down the rock layers into suitable blocks. Then, a cold recycling machine mills, crushes, and mixes the blasted stone materials to produce a recycled mixture. Throughout the entire process, the scope and intensity of the blasting must be strictly controlled to ensure the safety of the cold regeneration machine; At the same time, according to the particle size of the blasted stone, adjust the tool spacing and speed of the cold recycling machine to ensure the recycling effect.
