水泥撒布车的撒布精度是衡量设备性能的核心指标。对于粉料撒布车，核心要看“撒布精度”和“除尘效果”。要询问出租方车辆的控制系统是否具备自动恒速撒布功能——即车辆行驶速度变化时，撒布量依然保持恒定。同时检查车辆的除尘系统（如高压雾化加湿器或布袋除尘）是否正常工作，这不仅关乎环保检查能否过关，也直接影响现场工人的作业环境。粉料仓的密封性同样重要，漏粉不仅浪费材料，还会导致撒布量不足。

The spreading accuracy of cement spreader is the core indicator for measuring equipment performance. For powder spreading vehicles, the key factors to consider are "spreading accuracy" and "dust removal effect". To inquire whether the control system of the lessor's vehicle has an automatic constant speed spreading function - that is, when the vehicle's speed changes, the spreading amount remains constant. At the same time, checking whether the vehicle's dust removal system (such as high-pressure atomizing humidifiers or bag dust collectors) is working properly is not only related to whether the environmental inspection can pass, but also directly affects the working environment of on-site workers. The sealing of the powder silo is equally important, as powder leakage not only wastes materials but also leads to insufficient spreading.

对于水泥净浆洒布车，核心要看“搅拌能力”和“喷洒系统”——检查搅拌罐是否能将水泥浆搅拌均匀、有无沉淀死角；喷嘴是否有磨损或堵塞、喷洒宽度是否可调节（通常在3至4米之间）、喷洒压力是否稳定。如果喷嘴雾化效果差，水泥浆会呈水柱状流出，严重影响路面粘结质量。

For cement slurry spraying trucks, the core depends on the "mixing capacity" and "spraying system" - checking whether the mixing tank can mix the cement slurry evenly and whether there are any dead corners for sedimentation; Whether the nozzle is worn or blocked, whether the spraying width is adjustable (usually between 3 and 4 meters), and whether the spraying pressure is stable. If the atomization effect of the nozzle is poor, the cement slurry will flow out in the form of a water column, seriously affecting the bonding quality of the road surface.

现场安全管理要点

Key points of on-site safety management

操作手应熟练掌握自动与手动两套配料系统的切换，并在加料过程中密切关注料满报警提示。在施工现场，项目部应与租赁方共同签订安管合同，监督司机严格遵守现场规章制度。

The operator should be proficient in switching between automatic and manual batching systems, and closely monitor the full material alarm prompt during the feeding process. At the construction site, the project department should jointly sign a safety management contract with the lessee to supervise the drivers to strictly comply with the on-site rules and regulations.

打料时需特别注意：不同型号的车辆容积不同，打料时要特别注意容积限制，以免过满造成车厢撑鼓变形甚至开裂。保持罐车打料管和撒布车打料口在同一位置，避免弯折。撒布操作系统页面有材料密度设定，可根据实际材料密度调整称重报警提醒。水泥的比重多受原材料比重影响；白灰的比重多受干湿度、掺杂的石粉和颗粒料含量影响，施工时要特别留意打料量。

Special attention should be paid when feeding: different models of vehicles have different capacities, so special attention should be paid to the capacity limit when feeding to avoid overfilling causing deformation or even cracking of the carriage support. Keep the feeding tube of the tanker truck and the feeding port of the spreader truck in the same position to avoid bending. The spreading operating system page has material density settings, which can adjust the weighing alarm reminder according to the actual material density. The specific gravity of cement is often influenced by the specific gravity of raw materials; The specific gravity of white ash is often affected by dry humidity, the content of mixed stone powder and granular materials, so special attention should be paid to the amount of material used during construction.
