来源：http://www.ycgjglcl.com/ 日期：2025-04-07
在城市道路建设和维护中，各类机械设备如同勤劳的 “钢铁工匠”，默默塑造着我们脚下的出行环境。这些看似笨重的机器，实则蕴含着精密的工程学原理，在不同施工环节发挥着不可替代的作用。
In the construction and maintenance of urban roads, various types of mechanical equipment are like hardworking "steel craftsmen" silently shaping the travel environment under our feet. These seemingly bulky machines actually contain precise engineering principles and play an irreplaceable role in different construction stages.
一、核心设备的分工协作
1、 Division of labor and collaboration of core equipment
1. 摊铺机：路面成型的 “画布大师”
1. Paver: the "canvas master" of road surface shaping
摊铺机通过螺旋布料器将沥青混合料均匀摊铺在路基上，形成平整的路面基层。某型号摊铺机的振捣频率可达 4000 次 / 分钟，摊铺厚度误差控制在 ±2mm 以内。在济南经十路改造中，摊铺机每小时可摊铺宽度 8 米、厚度 6 厘米的沥青层，相当于每分钟铺设一个篮球场大小的路面。
The paver evenly spreads the asphalt mixture on the roadbed through a spiral distributor, forming a smooth pavement base. The vibration frequency of a certain model of paver can reach 4000 times per minute, and the paving thickness error is controlled within ± 2mm. In the renovation of Jingshi Road in Jinan, the paver can spread an asphalt layer with a width of 8 meters and a thickness of 6 centimeters per hour, which is equivalent to laying a basketball court sized road surface every minute.
2. 压路机：压实质量的 “重量专家”
2. Road roller: the "weight expert" of compaction quality
压路机依靠自身重量或振动功能，将松散的混合料压实成紧密结构。双钢轮压路机适合初压阶段，通过 12-16 吨静重消除摊铺层空隙；轮胎压路机则用于终压，凭借 20-25 吨气压轮胎的揉搓作用，使路面达到 98% 以上的压实度。某施工数据显示，经过压路机处理的路面，承载能力比未压实前提升 5 倍。
The roller relies on its own weight or vibration function to compact loose mixtures into a compact structure. Double drum rollers are suitable for the initial compaction stage, eliminating gaps in the paving layer through a static weight of 12-16 tons; The tire roller is used for final compaction, relying on the kneading effect of 20-25 ton pneumatic tires to achieve a compaction degree of over 98% on the road surface. According to certain construction data, the bearing capacity of the road surface treated with a roller has increased by 5 times compared to before compaction.
3. 铣刨机：病害修复的 “外科医生”
3. Milling machine: the "surgeon" for disease repair
铣刨机通过旋转刀头将破损路面铣削成规则创面，最大铣刨深度可达 30 厘米。在济南纬二路改造中，铣刨机每小时可处理 200 平方米病害路面，比人工凿除效率提高 40 倍。铣削产生的废旧材料可回收利用，再生利用率达 85% 以上。
The milling machine grinds damaged road surfaces into regular wounds by rotating the cutting head, with a maximum milling depth of up to 30 centimeters. In the renovation of Wei'er Road in Jinan, the milling machine can process 200 square meters of damaged road surface per hour, which is 40 times more efficient than manual chiseling. The waste materials generated by milling can be recycled, with a recycling rate of over 85%.
二、选型决策的关键因素
2、 Key factors in selection decision-making
1. 施工场景适配
1. Construction scene adaptation
新建道路：优先选择大宽度摊铺机（≥9 米）和重型压路机（≥25 吨），某工程测算显示，这种组合可使施工效率提升 35%。
New road construction: Priority should be given to wide width pavers (≥ 9 meters) and heavy-duty rollers (≥ 25 tons). According to calculations from a certain project, this combination can increase construction efficiency by 35%.
旧路维修：需配备小型铣刨机（≤1.2 米铣刨宽度）和轻型压路机（≤8 吨），某市政公司经验表明，这类设备在狭窄路段的施工效率比大型设备高 60%。
Old road maintenance: Small milling machines (≤ 1.2 meters milling width) and lightweight rollers (≤ 8 tons) are required. The experience of a municipal company shows that the construction efficiency of such equipment in narrow road sections is 60% higher than that of large equipment.
2. 材料特性匹配
2. Material characteristic matching
沥青混合料：根据集料粒径选择摊铺机振捣频率，粗粒式沥青需采用低频高幅振捣（2000-2500 次 / 分钟），细粒式则用高频低幅（3000-3500 次 / 分钟）。
Asphalt mixture: Select the compaction frequency of the paver according to the particle size of the aggregate. Coarse grained asphalt should be compacted with low frequency and high amplitude (2000-2500 times/minute), while fine-grained asphalt should be compacted with high frequency and low amplitude (3000-3500 times/minute).
水泥稳定碎石：压路机需采用 “先轻后重、先慢后快” 的压实工艺，某实验数据显示，最佳压实速度为 2-4km/h，过快会导致结构松散。
Cement stabilized crushed stone: The roller needs to adopt a compaction process of "light first, heavy second, slow first, fast second". Experimental data shows that the optimal compaction speed is 2-4 km/h, and too fast will cause the structure to loosen.
3. 气候条件应对
3. Climate response
高温施工：摊铺机需配备喷雾降温装置，某测试显示，该装置可使沥青混合料温度损失减少 20℃，确保摊铺质量。
High temperature construction: the paver needs to be equipped with a spray cooling device. A test shows that the device can reduce the temperature loss of asphalt mixture by 20 ℃ to ensure the paving quality.
冬季施工：压路机需加装保温罩，某工程案例表明，保温罩可使碾压温度保持在 120℃以上，满足施工规范要求。
Winter construction: The roller needs to be equipped with an insulation cover. A certain engineering case shows that the insulation cover can keep the rolling temperature above 120 ℃, meeting the construction specifications.
