水泥撒布车作为路面基层施工的关键设备，凭借其精准、的水泥撒布能力，在各类工程中发挥着不可替代的作用。其通过机械传动控制撒布量，能均匀铺设水泥等胶凝材料，大幅提升施工效率并减少材料浪费。从道路新建到养护维修，从市政工程到特殊场地处理，水泥撒布车的适用范围广泛，以下结合工程特点具体解析。

　　As a key equipment for road base construction, cement spreader plays an irreplaceable role in various projects with its precise and efficient cement spreading ability. It controls the spreading amount through mechanical transmission, which can evenly lay cement and other cementitious materials, greatly improving construction efficiency and reducing material waste. From road construction to maintenance and repair, from municipal engineering to special site treatment, cement spreading vehicles have a wide range of applications. The following is a specific analysis based on the characteristics of the project.

　　新建道路基层稳定土施工

　　Construction of stabilized soil for new road base

　　在各级公路的新建工程中，水泥稳定土基层施工是水泥撒布车的核心应用场景。无论是高速公路的底基层、基层，还是县乡公路的路面结构层，均需将水泥与土料按比例混合压实。传统人工撒布水泥易出现分布不均、剂量偏差大等问题，而水泥撒布车可通过调节撒布宽度（通常 3-6 米）和厚度（0.5-5 厘米），实现每水泥用量的精准控制（误差≤1%），确保稳定土强度均匀。

　　In the construction of new highways at all levels, the construction of cement stabilized soil base is the core application scenario of cement spreading vehicles. Whether it is the subgrade or base layer of highways, or the pavement structure layer of county and township highways, cement and soil materials need to be mixed and compacted in proportion. Traditional manual spreading of cement is prone to problems such as uneven distribution and large dosage deviation. However, cement spreading vehicles can achieve precise control of cement dosage per square meter (error ≤ 1%) by adjusting the spreading width (usually 3-6 meters) and thickness (0.5-5 centimeters), ensuring uniform strength of stable soil.

　　以二级公路施工为例，当基层采用水泥粉煤灰稳定碎石时，水泥撒布车可配合平地机、压路机联合作业：先通过撒布车均匀铺设水泥，再经平地机拌和、压路机碾压，形成连续稳定的结构层。这种施工方式较人工撒布效率提升 5-8 倍，尤其适合长距离路段（如城郊连接线）的规模化施工，能有效缩短工期。

　　Taking the construction of second-class highway as an example, when the cement fly ash stabilized macadam is used as the base course, the cement spreader can cooperate with the grader and the road roller for joint operation: first, the cement is evenly laid by the spreader, then mixed by the grader and rolled by the road roller to form a continuous and stable structural layer. This construction method is 5-8 times more efficient than manual spreading, especially suitable for large-scale construction of long-distance road sections (such as suburban connecting lines), which can effectively shorten the construction period.

　　市政道路养护与修补工程

　　Municipal road maintenance and repair project

　　城市道路的日常养护和应急修补中，水泥撒布车的灵活性优势尤为突出。当城市主干道出现基层松散、网裂等病害时，需进行局部开挖修补：先将破损区域清理稳定基层，再用撒布车精准撒布水泥，配合洒水车湿润、小型拌和机搅拌，快速完成基层修复。其可调节的撒布范围（小可控制在 1 内），能适应检查井周边、路口转角等狭小区域的施工需求。

　　In the daily maintenance and emergency repair of urban roads, the flexibility advantage of cement spreading vehicles is particularly prominent. When the main roads in the city suffer from loose grassroots and cracked nets, local excavation and repair are required: first, clean the damaged area to a stable grassroots, then use a spreading truck to accurately spread cement, combined with a watering truck to moisten and a small mixer to quickly complete the grassroots repair. Its adjustable spreading range (minimum controllable within 1 square meter) can adapt to the construction needs of narrow areas such as inspection wells, intersection corners, etc.

　　在城市次干道的 “白改黑” 工程中，水泥撒布车用于旧路面碎石化后的基层处理。通过在破碎后的混凝土表面均匀撒布水泥，再喷洒乳化沥青形成粘结层，既能增强基层整体性，又能为后续沥青面层提供良好支撑。这种工艺尤其适合交通流量大的路段，可减少施工占用时间，降低对市民出行的影响。

　　In the "white to black" project of urban secondary roads, cement spreader trucks are used for the base treatment of old road surfaces that have been crushed and petrified. By evenly spreading cement on the surface of the crushed concrete and then spraying emulsified asphalt to form a bonding layer, it can enhance the overall integrity of the base layer and provide good support for the subsequent asphalt surface layer. This technology is particularly suitable for road sections with high traffic flow, which can reduce construction time and minimize the impact on citizens' travel.

　　机场跑道与货运场基层处理

　　Airport runway and cargo yard grassroots treatment

　　机场跑道的基层加固和货运场的硬化施工，对水泥撒布的精度和均匀性要求极高。机场跑道的土基处理阶段，需铺设水泥改良土以提高承载能力，水泥撒布车可按照设计剂量（通常 4%-6%）均匀撒布，确保经碾压后基层弯沉值符合航空标准（≤200με）。其封闭式料仓设计能减少风力对水泥撒布的影响，适应机场开阔场地的施工环境。

　　The base reinforcement of airport runways and the hardening construction of freight yards require extremely high precision and uniformity in cement spreading. In the soil foundation treatment stage of airport runways, cement modified soil needs to be laid to improve the bearing capacity. Cement spreading vehicles can evenly spread according to the design dosage (usually 4% -6%) to ensure that the base deflection value after compaction meets aviation standards (≤ 200 μ ε). Its enclosed silo design can reduce the impact of wind on cement spreading and adapt to the construction environment of open airport sites.

　　大型货运场（如物流园区、港口堆场）的硬化工程中，水泥撒布车常与装载机、摊铺机配合，用于水泥稳定碎石基层施工。针对堆场频繁承受重型货车碾压的特点，撒布车可通过加密撒布密度（每水泥用量增加 10%-15%）增强基层强度，配合振动压路机压实，使基层抗压强度达到 15MPa 以上，满足长期重载需求。

　　In the hardening project of large freight yards (such as logistics parks and port yards), cement spreader trucks are often used in conjunction with loaders and pavers for the construction of cement stabilized crushed stone base. In response to the frequent crushing of heavy trucks in the yard, the spreading vehicle can enhance the strength of the base layer by increasing the spreading density (increasing the cement consumption by 10% -15% per square meter), and compacting it with a vibrating roller to achieve a compressive strength of over 15MPa, meeting long-term heavy load requirements.

　　乡村公路与田间道路改造

　　Rural road and field road renovation

　　乡村公路升级改造和农田水利配套道路施工，是水泥撒布车的重要应用领域。乡村道路多为 3-5 米宽的四级公路，水泥撒布车可通过收缩撒布宽度适应路面尺寸，其灵活的转向性能适合乡村狭窄路段的作业。在路基处理阶段，撒布车将水泥均匀撒布在素土表面，经拖拉机牵引拌和机拌和后，形成简易水泥土基层，大幅提升道路承载能力（可承受 10 吨以下货车通行）。

　　The upgrading and renovation of rural roads and the construction of agricultural water conservancy supporting roads are important application areas for cement spreading vehicles. Most rural roads are fourth-class highway with a width of 3-5 meters. Cement spreaders can adapt to the road size by shrinking the spreading width, and their flexible steering performance is suitable for operations in narrow rural sections. In the roadbed treatment stage, the spreading vehicle evenly spreads cement on the surface of the plain soil, and after being mixed by a tractor pulled mixer, a simple cement soil base is formed, greatly improving the road bearing capacity (able to withstand the passage of trucks weighing less than 10 tons).

　　田间道路（如机耕道）的改造中，水泥撒布车的小型化车型（撒布宽度 2-3 米）更具优势。这类道路通常长度短、分布散，撒布车可快速转场作业，配合人工平整，实现 “低造价、率” 的改造目标。通过铺设 5-10 厘米厚的水泥土基层，能有效解决田间道路雨天泥泞、通行困难的问题，助力农业机械通行和农产品运输。

　　In the renovation of field roads (such as tractor roads), the miniaturized model of cement spreader (with a spreading width of 2-3 meters) has more advantages. These types of roads are usually short in length and scattered in distribution, and can be quickly transferred by scattering vehicles, combined with manual leveling, to achieve the goal of "low cost and high efficiency" in the renovation. By laying a 5-10 centimeter thick cement soil base, it can effectively solve the problem of muddy and difficult passage on field roads in rainy days, and assist in the passage of agricultural machinery and the transportation of agricultural products.
