水泥洒布车是道路建设与养护工程中用于精准喷洒水泥材料的专用设备，通过机械系统将水泥干粉或水泥浆按设定量均匀洒布在路面，为基层稳定、路基加固等施工环节提供关键支持，其高效性与精准性使其成为现代道路工程中的重要装备。

　　Cement sprinkler truck is a specialized equipment used for precise spraying of cement materials in road construction and maintenance projects. Through a mechanical system, it evenly distributes cement powder or slurry in a set amount on the road surface, providing key support for construction processes such as base stability and roadbed reinforcement. Its efficiency and precision make it an important equipment in modern road engineering.

　　在路面基层施工中，水泥洒布车承担着水泥稳定层的材料铺设任务。修建沥青或水泥路面时，需先在路基上铺设水泥稳定碎石基层，此时水泥洒布车可将水泥干粉均匀洒布在碎石层表面，洒布量根据设计要求（通常为碎石重量的 3%-5%）精准控制，误差不超过 ±0.5%。洒布完成后，经拌和设备搅拌，水泥与碎石、水充分反应，形成具有一定强度的稳定层，7 天无侧限抗压强度可达 2-4MPa，为路面提供坚实基础。相比人工撒布，机械洒布能避免水泥堆积或漏撒，确保稳定层强度均匀，减少后期因局部强度不足产生的路面沉降。

　　In the construction of the road base layer, the cement sprinkler truck is responsible for laying the material for the cement stabilized layer. When constructing asphalt or cement pavement, it is necessary to first lay a cement stabilized crushed stone base layer on the roadbed. At this time, the cement distributor can evenly distribute the cement dry powder on the surface of the crushed stone layer, and the spraying amount is precisely controlled according to the design requirements (usually 3% -5% of the weight of the crushed stone), with an error not exceeding ± 0.5%. After the spraying is completed, the cement reacts fully with crushed stones and water through mixing equipment, forming a stable layer with a certain strength. The unconfined compressive strength can reach 2-4MPa after 7 days, providing a solid foundation for the road surface. Compared to manual spreading, mechanical spreading can avoid cement accumulation or leakage, ensure uniform strength of the stable layer, and reduce road settlement caused by insufficient local strength in the later stage.

　　路基加固工程中，水泥洒布车可实现就地固化处理。对于软土地基或路基翻浆路段，需通过掺入水泥改善土壤特性，水泥洒布车能将水泥浆均匀喷洒在翻挖后的土壤表面，洒布宽度可根据施工路段调整（通常 3-6 米），确保每平方米土壤的水泥掺入量符合设计标准（如 5%-8%）。经拌和、碾压后，水泥与土壤发生化学反应，形成板体结构，提高路基承载力，减少工后沉降。在乡村道路拓宽工程中，这种就地固化工艺可利用原有土壤，减少外运弃土与新土进场，每公里可节省材料运输成本 20% 以上。

　　In roadbed reinforcement projects, cement spraying trucks can achieve on-site solidification treatment. For sections with soft soil foundation or subgrade slurry, it is necessary to improve soil characteristics by adding cement. Cement sprinklers can evenly spray cement slurry on the excavated soil surface, and the spraying width can be adjusted according to the construction section (usually 3-6 meters) to ensure that the cement content per square meter of soil meets the design standards (such as 5% -8%). After mixing and rolling, cement reacts chemically with soil to form a slab structure, which improves the bearing capacity of the roadbed and reduces post construction settlement. In rural road widening projects, this in-situ solidification process can utilize existing soil, reduce the need for external transportation of abandoned soil and the entry of new soil, and save more than 20% of material transportation costs per kilometer.

　　路面养护中的局部修复是其另一重要应用。当沥青路面出现松散、麻面等表层病害时，可先用铣刨机清除破损层，水泥洒布车随后喷洒少量水泥浆（每平方米 0.5-1.0kg），浸润基层表面，增强新铺沥青层与原基层的黏结力，防止出现层间剥离。在水泥路面裂缝修复中，对于宽度大于 5mm 的裂缝，可通过洒布车将水泥浆灌入裂缝，填充空隙后初凝，再进行后续密封处理，提升裂缝修复的耐久性。此外，在路面 “白改黑”（水泥路面改沥青路面）工程中，洒布车喷洒的水泥净浆能封闭原水泥路面的细微裂缝，阻断地下水渗透路径，保护基层稳定。

　　Local repair in road maintenance is another important application. When there are surface defects such as looseness and roughness on the asphalt pavement, a milling machine can be used to remove the damaged layer first, and a cement sprayer can then spray a small amount of cement slurry (0.5-1.0kg per square meter) to wet the surface of the base layer, enhance the adhesion between the newly laid asphalt layer and the original base layer, and prevent interlayer peeling. In the repair of cracks on cement pavement, for cracks with a width greater than 5mm, cement slurry can be poured into the cracks by a sprinkler truck, filled in the gaps, and then initially set, followed by subsequent sealing treatment to improve the durability of crack repair. In addition, in the road surface "white to black" (cement road surface to asphalt road surface) project, the cement slurry sprayed by the sprinkler truck can seal the fine cracks of the original cement road surface, block the groundwater infiltration path, and protect the stability of the base layer.

　　特殊路面施工中展现灵活适配性。修建透水路面时，水泥洒布车可将低标号水泥浆按特定量洒布在透水骨料表面，形成强度适中的胶结层，既保证路面透水性，又满足基本承载要求。在砂石路面升级为简易硬化路面时，洒布车均匀喷洒水泥干粉后，配合洒水车补水拌和，经碾压形成水泥稳定砂石路面，适用于乡村低交通量道路，每公里建设成本仅为沥青路面的三分之一。对于临时施工便道，洒布车快速洒布水泥并拌和碾压，可在 24 小时内形成临时硬化路面，满足施工车辆通行需求，工程结束后还可破碎回收，减少对场地的永久占用。

　　Show flexibility and adaptability in the construction of special road surfaces. When constructing permeable pavements, cement sprinklers can spray low-grade cement slurry in a specific amount on the surface of permeable aggregates to form a moderately strong bonding layer, which ensures the permeability of the pavement and meets the basic bearing requirements. When upgrading a gravel road surface to a simple hardened road surface, the sprinkler truck evenly sprays cement dry powder, and then mixes it with the sprinkler truck to form a cement stabilized gravel road surface through rolling. It is suitable for low traffic volume rural roads, and the construction cost per kilometer is only one-third of that of asphalt roads. For temporary construction access roads, the sprinkler truck can quickly spread cement and mix and roll it, forming a temporarily hardened road surface within 24 hours to meet the traffic needs of construction vehicles. After the project is completed, it can also be broken and recycled to reduce permanent occupation of the site.
