在建筑施工領(lǐng)域，冷再生機(jī)憑借其、、的特點(diǎn)，成為舊路面改造與資源循環(huán)利用的重要設(shè)備。隨著租賃模式的普及，越來(lái)越多施工單位選擇租賃冷再生機(jī)完成工程。然而，冷再生機(jī)的正常運(yùn)行與環(huán)境條件密切相關(guān)，充分了解其對(duì)環(huán)境的要求，不僅關(guān)系到設(shè)備性能的發(fā)揮，更影響工程質(zhì)量與生態(tài)效益。

　　In the field of construction, cold recycling machines have become important equipment for old road surface renovation and resource recycling due to their high efficiency, energy saving, and environmental protection characteristics. With the popularization of leasing models, more and more construction units choose to lease cold recycling machines to complete projects. However, the normal operation of the cold regeneration machine is closely related to environmental conditions. Fully understanding its requirements for the environment not only affects the performance of the equipment, but also affects the quality of the project and ecological benefits.

　　一、氣候條件對(duì)冷再生機(jī)租賃使用的影響

　　1、 The impact of climate conditions on the rental and use of cold recycling machines

　　溫度環(huán)境：冷再生機(jī)的作業(yè)對(duì)溫度有一定要求。適宜的作業(yè)溫度通常在 5℃ - 35℃之間。溫度過(guò)低時(shí)，路面材料變得堅(jiān)硬，冷再生機(jī)的刀具磨損加劇，設(shè)備動(dòng)力系統(tǒng)的效率降低，液壓油黏度增加，導(dǎo)致設(shè)備啟動(dòng)困難、運(yùn)行阻力增大；同時(shí)，添加劑與舊路面材料的化學(xué)反應(yīng)也會(huì)受到抑制，影響再生混合料的質(zhì)量。當(dāng)溫度過(guò)高時(shí)，一方面，設(shè)備的發(fā)動(dòng)機(jī)、液壓系統(tǒng)容易過(guò)熱，出現(xiàn)故障的概率大幅上升，如發(fā)動(dòng)機(jī)功率下降、液壓系統(tǒng)泄漏等；另一方面，再生混合料中的水分蒸發(fā)過(guò)快，不利于材料的均勻拌和與壓實(shí)成型。因此，在極端氣溫條件下租賃使用冷再生機(jī)，需采取特殊措施，如冬季對(duì)設(shè)備進(jìn)行預(yù)熱、添加低溫適用的潤(rùn)滑油和液壓油，夏季加強(qiáng)設(shè)備的散熱，合理安排作業(yè)時(shí)間，避開(kāi)高溫時(shí)段。

　　Temperature environment: The operation of the cold regeneration machine has certain temperature requirements. The suitable operating temperature is usually between 5 ℃ and 35 ℃. When the temperature is too low, the road surface material becomes hard, the tool wear of the cold recycling machine intensifies, the efficiency of the equipment power system decreases, the viscosity of the hydraulic oil increases, resulting in difficulty in starting the equipment and increased operating resistance; At the same time, the chemical reaction between additives and old pavement materials will also be inhibited, affecting the quality of recycled mixtures. When the temperature is too high, on the one hand, the engine and hydraulic system of the equipment are prone to overheating, and the probability of failure increases significantly, such as a decrease in engine power, hydraulic system leakage, etc; On the other hand, the rapid evaporation of moisture in the recycled mixture is not conducive to the uniform mixing and compaction of the material. Therefore, in extreme temperature conditions, special measures need to be taken to lease and use cold regeneration machines, such as preheating the equipment in winter, adding lubricating oil and hydraulic oil suitable for low temperature, strengthening equipment heat dissipation in summer, arranging operation time reasonably, and avoiding high temperature periods.

　　濕度與降水：環(huán)境濕度和降水情況對(duì)冷再生機(jī)作業(yè)影響顯著。濕度較大或連續(xù)降雨時(shí)，舊路面材料含水量過(guò)高，會(huì)使再生混合料的含水率超標(biāo)，導(dǎo)致混合料黏附性變差，難以壓實(shí)，成型后的路面強(qiáng)度和穩(wěn)定性下降。此外，潮濕環(huán)境還會(huì)加速設(shè)備金屬部件的銹蝕，影響冷再生機(jī)的使用壽命，尤其是刀具、攪拌裝置等關(guān)鍵部件。因此，在雨天或濕度較大的環(huán)境中，應(yīng)避免使用冷再生機(jī)作業(yè)，若工期緊張無(wú)法避免，需提前對(duì)路面進(jìn)行排水處理，如設(shè)置排水溝、使用排水設(shè)備等，并適當(dāng)調(diào)整添加劑的用量，以保證再生混合料的質(zhì)量；同時(shí)，加強(qiáng)設(shè)備的防潮防銹措施，作業(yè)結(jié)束后及時(shí)對(duì)設(shè)備進(jìn)行清潔和保養(yǎng)。

　　Humidity and precipitation: Environmental humidity and precipitation have a significant impact on the operation of cold recycling machines. When the humidity is high or there is continuous rainfall, the moisture content of the old pavement material is too high, which will cause the moisture content of the recycled mixture to exceed the standard, resulting in poor adhesion of the mixture, difficulty in compaction, and a decrease in the strength and stability of the formed pavement. In addition, humid environments can accelerate the corrosion of equipment metal components, affecting the service life of cold recycling machines, especially key components such as cutting tools and mixing devices. Therefore, in rainy days or environments with high humidity, the use of cold recycling machines should be avoided. If the schedule is tight and cannot be avoided, the road surface should be drained in advance, such as setting up drainage ditches, using drainage equipment, etc., and adjusting the amount of additives appropriately to ensure the quality of the recycled mixture; At the same time, strengthen the moisture-proof and rust proof measures of the equipment, and clean and maintain the equipment in a timely manner after the operation is completed.

　　二、地形與場(chǎng)地條件的適配要求

　　2、 Adaptation requirements for terrain and site conditions

　　地形坡度：冷再生機(jī)適宜在平坦或坡度較小的場(chǎng)地作業(yè)。當(dāng)作業(yè)場(chǎng)地坡度較大時(shí)，設(shè)備容易出現(xiàn)偏移，導(dǎo)致行駛穩(wěn)定性下降，增加設(shè)備傾覆的風(fēng)險(xiǎn)；同時(shí)，在坡面上進(jìn)行破碎、拌和等作業(yè)時(shí)，刀具受力不均勻，會(huì)加劇磨損，影響作業(yè)效果和設(shè)備壽命。一般來(lái)說(shuō)，冷再生機(jī)作業(yè)場(chǎng)地的坡度不宜超過(guò) 15°。若施工場(chǎng)地坡度超出限制，需對(duì)場(chǎng)地進(jìn)行平整處理，或采取特殊的防護(hù)措施，如在設(shè)備上安裝防滑鏈、設(shè)置牽引裝置等，確保設(shè)備運(yùn)行。

　　Terrain slope: The cold recycling machine is suitable for operating on flat or low slope sites. When the slope of the work site is large, the equipment is prone to center of gravity deviation, which leads to a decrease in driving stability and increases the risk of equipment overturning; At the same time, when crushing, mixing and other operations are carried out on the slope, the uneven force on the cutting tools will intensify wear and affect the operation effect and equipment life. Generally speaking, the slope of the cold recycling machine operation site should not exceed 15 °. If the slope of the construction site exceeds the limit, the site needs to be leveled or special safety protection measures should be taken, such as installing anti-skid chains on equipment, setting up traction devices, etc., to ensure the safe operation of the equipment.

　　場(chǎng)地平整度與承載力：冷再生機(jī)運(yùn)行需要堅(jiān)實(shí)、平整的場(chǎng)地。不平整的場(chǎng)地會(huì)使設(shè)備在行駛和作業(yè)過(guò)程中產(chǎn)生顛簸，影響破碎和拌和的均勻性，降低再生混合料的質(zhì)量；同時(shí)，顛簸還會(huì)對(duì)設(shè)備的零部件造成沖擊，加速設(shè)備損壞。此外，若場(chǎng)地承載力不足，冷再生機(jī)在作業(yè)時(shí)可能會(huì)出現(xiàn)下陷，導(dǎo)致設(shè)備無(wú)法正常運(yùn)行，甚損壞設(shè)備。因此，在租賃冷再生機(jī)前，需對(duì)施工場(chǎng)地進(jìn)行勘察和評(píng)估，確保場(chǎng)地平整度符合要求，對(duì)松軟場(chǎng)地進(jìn)行壓實(shí)處理，或鋪設(shè)鋼板等增強(qiáng)場(chǎng)地承載力，為冷再生機(jī)提供良好的作業(yè)基礎(chǔ)。

　　Flatness and bearing capacity of the site: The operation of the cold recycling machine requires a solid and flat site. Uneven terrain can cause equipment to experience bumps during driving and operation, affecting the uniformity of crushing and mixing, and reducing the quality of recycled mixtures; At the same time, bumps can also cause impact on the components of the equipment, accelerating equipment damage. In addition, if the bearing capacity of the site is insufficient, the cold recycling machine may sink during operation, causing the equipment to malfunction and even damage it. Therefore, before leasing a cold recycling machine, it is necessary to conduct a survey and evaluation of the construction site to ensure that the flatness of the site meets the requirements. The soft site should be compacted or steel plates should be laid to enhance the bearing capacity of the site, providing a good working foundation for the cold recycling machine.

　　三、周邊環(huán)境因素的考量

　　3、 Consideration of surrounding environmental factors

　　噪音與振動(dòng)控制：冷再生機(jī)在作業(yè)過(guò)程中會(huì)產(chǎn)生較大的噪音和振動(dòng)，對(duì)周邊居民生活和建筑物造成影響。在居民區(qū)、學(xué)校、醫(yī)院等噪聲敏感區(qū)域施工時(shí)，需嚴(yán)格遵守當(dāng)?shù)氐脑胍襞欧艠?biāo)準(zhǔn)，合理安排作業(yè)時(shí)間，避免在居民休息時(shí)段進(jìn)行高噪音作業(yè)；同時(shí)，可采取降噪措施，如安裝隔音裝置、使用低噪音刀具等，降低設(shè)備運(yùn)行噪音。對(duì)于周邊的建筑物，尤其是老舊建筑或?qū)φ駝?dòng)敏感的精密儀器設(shè)備，過(guò)大的振動(dòng)可能導(dǎo)致建筑物結(jié)構(gòu)損壞或儀器設(shè)備精度下降。因此，在施工前需對(duì)周邊建筑物進(jìn)行評(píng)估，必要時(shí)采取隔振措施，如設(shè)置隔振溝、使用隔振材料等，減少振動(dòng)對(duì)周邊環(huán)境的影響。

　　Noise and vibration control: The cold regeneration machine will generate significant noise and vibration during operation, which will have an impact on the lives of surrounding residents and buildings. When constructing in noise sensitive areas such as residential areas, schools, hospitals, etc., it is necessary to strictly comply with local noise emission standards, arrange work time reasonably, and avoid high noise operations during residents' rest periods; At the same time, noise reduction measures can be taken, such as installing sound insulation devices, using low-noise cutting tools, etc., to reduce the operating noise of the equipment. For surrounding buildings, especially old buildings or precision instruments and equipment that are sensitive to vibration, excessive vibration may cause structural damage to the building or a decrease in the accuracy of the instruments and equipment. Therefore, before construction, it is necessary to evaluate the surrounding buildings and take vibration isolation measures if necessary, such as setting up vibration isolation trenches, using vibration isolation materials, etc., to reduce the impact of vibration on the surrounding environment.

　　粉塵污染防治：冷再生機(jī)破碎舊路面材料時(shí)會(huì)產(chǎn)生大量粉塵，不僅污染空氣環(huán)境，危害施工人員和周邊居民的身體健康，還可能影響設(shè)備的正常運(yùn)行，如粉塵進(jìn)入發(fā)動(dòng)機(jī)、液壓系統(tǒng)等部件，會(huì)加速設(shè)備磨損，降低設(shè)備性能。因此，在租賃使用冷再生機(jī)時(shí)，需配備有效的粉塵防治措施，如安裝噴水降塵裝置，在作業(yè)過(guò)程中持續(xù)噴水，抑制粉塵飛揚(yáng)；同時(shí)，為施工人員配備防塵口罩等防護(hù)用品，保障人員健康；對(duì)施工現(xiàn)場(chǎng)周邊的道路進(jìn)行定期清掃和灑水，減少粉塵擴(kuò)散。

　　Dust pollution prevention and control: When the cold recycling machine crushes old road materials, it generates a large amount of dust, which not only pollutes the air environment and endangers the health of construction workers and surrounding residents, but also may affect the normal operation of equipment. For example, dust entering components such as engines and hydraulic systems can accelerate equipment wear and reduce equipment performance. Therefore, when renting and using a cold recycling machine, effective dust prevention measures should be equipped, such as installing a water spray dust reduction device, continuously spraying water during the operation process to suppress dust flying; At the same time, equip construction personnel with dust masks and other protective equipment to ensure their health; Regularly clean and sprinkle water on the roads around the construction site to reduce dust dispersion.
