在道路養(yǎng)護(hù)與改造工程中，冷再生機(jī)因其、經(jīng)濟(jì)的特點(diǎn)，已成為處理舊路面材料的設(shè)備。為確保施工質(zhì)量與效率，必須嚴(yán)格按照規(guī)范流程操作，下面將詳細(xì)說(shuō)明使用冷再生機(jī)的具體方法。

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.

施工前的準(zhǔn)備工作關(guān)重要，要對(duì)作業(yè)路段進(jìn)行細(xì)致的勘察。技術(shù)人員需要準(zhǔn)確評(píng)估道路損壞程度，仔細(xì)檢查基層結(jié)構(gòu)狀況，并確認(rèn)地下管線分布位置。針對(duì)基層存在嚴(yán)重病害的路段，如出現(xiàn)大面積坑槽或松散現(xiàn)象，必須預(yù)先制定專項(xiàng)處理方案。同時(shí)要根據(jù)道路實(shí)際尺寸和工期要求，科學(xué)規(guī)劃設(shè)備行進(jìn)路線和工作區(qū)域，避免出現(xiàn)重復(fù)施工或遺漏作業(yè)的情況。

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.

設(shè)備檢查環(huán)節(jié)需要關(guān)注機(jī)械部件的運(yùn)行狀態(tài)。操作人員應(yīng)當(dāng)仔細(xì)檢查發(fā)動(dòng)機(jī)各項(xiàng)油液是否充足，查看傳動(dòng)皮帶松緊度是否合適，確認(rèn)液壓系統(tǒng)管路連接牢固無(wú)泄漏。特別要注意檢查轉(zhuǎn)子刀具的磨損情況，磨損嚴(yán)重的刀具必須立即更換。電氣系統(tǒng)方面，要確保所有線路完好無(wú)損，各類儀表指示燈工作正常。設(shè)備調(diào)試時(shí)需進(jìn)行空載試運(yùn)行，調(diào)整轉(zhuǎn)子轉(zhuǎn)速和噴灑系統(tǒng)參數(shù)，確保其符合施工技術(shù)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.

材料準(zhǔn)備工作同樣不可忽視，必須根據(jù)設(shè)計(jì)要求準(zhǔn)備足量的乳化瀝青、水泥等添加劑。所有材料都要經(jīng)過(guò)嚴(yán)格的質(zhì)量檢測(cè)，確保各項(xiàng)指標(biāo)符合標(biāo)準(zhǔn)規(guī)范。同時(shí)要對(duì)回收的舊料進(jìn)行級(jí)配分析和含水量測(cè)試，為后續(xù)的配合比設(shè)計(jì)提供準(zhǔn)確依據(jù)。

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.

施工作業(yè)過(guò)程中，要將冷再生機(jī)準(zhǔn)確就位。操作人員需要調(diào)整設(shè)備位置，使轉(zhuǎn)子中心線與道路中心線完全對(duì)齊，并通過(guò)支腿調(diào)平設(shè)備。參數(shù)設(shè)置方面，要根據(jù)路面材料硬度合理確定轉(zhuǎn)子轉(zhuǎn)速，通常控制在3-6米/分鐘的行進(jìn)速度較為適宜。拌和深度必須嚴(yán)格按照設(shè)計(jì)要求控制，確保舊料與添加劑充分混合又不損傷路基。添加劑噴灑系統(tǒng)要保持穩(wěn)定運(yùn)行，確保按比例均勻噴灑。

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.

實(shí)際操作時(shí)，要先啟動(dòng)轉(zhuǎn)子達(dá)到設(shè)定轉(zhuǎn)速，再緩慢推進(jìn)設(shè)備。作業(yè)過(guò)程中要持續(xù)監(jiān)控發(fā)動(dòng)機(jī)轉(zhuǎn)速、液壓壓力等關(guān)鍵參數(shù)，同時(shí)觀察混合料的均勻程度。完成拌和后要及時(shí)進(jìn)行攤鋪壓實(shí)作業(yè)，采用先輕后重的碾壓方式，確保路面達(dá)到設(shè)計(jì)要求的平整度和密實(shí)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.

施工結(jié)束后的維護(hù)工作同樣重要。要徹底清洗設(shè)備各部件，特別是轉(zhuǎn)子和噴灑系統(tǒng)。完成清洗后要對(duì)所有潤(rùn)滑點(diǎn)加注潤(rùn)滑油，檢查緊固件狀態(tài)。質(zhì)量檢測(cè)環(huán)節(jié)需要使用儀器測(cè)量路面壓實(shí)度和平整度，發(fā)現(xiàn)問(wèn)題要及時(shí)處理。要清理施工現(xiàn)場(chǎng)，修復(fù)受損的附屬設(shè)施，確保道路恢復(fù)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.

通過(guò)規(guī)范化的操作流程和細(xì)致的維護(hù)保養(yǎng)，不僅能保證施工質(zhì)量，還能顯著延長(zhǎng)設(shè)備使用壽命。如需了解更詳細(xì)的故障排查方法或特殊工況下的操作技巧，歡迎隨時(shí)咨詢技術(shù)人員。

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. If you need more detailed troubleshooting methods or operating skills under special working conditions, please feel free to consult professional technicians at any time.
