压路机的操作控制对路面压实效果的影响
来源：/ 日期：2023-04-26
无论是压路机的任何操作控制，必须保证操作台和座椅固定牢靠的前提下进行，尤其是可移动式操作台和座椅。下面济南压路机出租人员就阐述一下压路机的操作控制对路面压实效果的影响。
Regardless of any operation control of the roller, it is necessary to ensure that the operating platform and seat are firmly fixed, especially the movable operating platform and seat. Below, Jinan roller rental personnel will elaborate on the impact of roller operation control on the compaction effect of the road surface.
压路机的操作控制主要有：行走控制、转向控制、振动控制、喷水量控制，以及一些碾压操作技巧上的控制。
The operation control of road rollers mainly includes: walking control, steering control, vibration control, water spray control, and some control techniques for rolling operations.
压路机的行走控制
Walking control of road rollers
要保证控制手柄控操灵活且有手感，不紧不松。起步时要轻缓，不可起步过急否则驱动轮会形成向后推移的作用力，使松铺沥青层造成推移现象，影响压实效果。
Ensure that the control handle is flexible and tactile, not tight or loose. When starting, it should be gentle and not too fast, otherwise the driving wheel will form a backward pushing force, causing the loose asphalt layer to push and affect the compaction effect.
运行时要保证匀速行驶，按照施工要求，初压一般控制在1.5m/h~2Km/h，复压控制在4m/h~5Km/h，终压控制在2m/h~3Km/h。压实过程中的瞬间停车不可过急，否则与急起步相同会造成松铺沥青层的推移现象。
During operation, it is necessary to ensure uniform driving speed. According to construction requirements, the initial pressure is generally controlled at 1.5m/h-2Km/h, the re pressure is controlled at 4m/h-5Km/h, and the final pressure is controlled at 2m/h-3Km/h. The instantaneous stop during the compaction process should not be too rapid, otherwise it will cause the same phenomenon as the rapid start, which will cause the loose asphalt layer to move.
压路机的转向控制
Steering control of roller
压路机在碾压转向变幅时，必须轻缓流畅，转弯半径不可过小，速度不可过快。否则，由于转向时的惯性和离心力会造成沥青混合料的挤压推移，影响路面的压实效果。
When rolling and turning, the roller must be gentle and smooth, with a turning radius that is not too small and a speed that is not too fast. Otherwise, due to the inertia and centrifugal force during turning, the asphalt mixture will be squeezed and pushed, affecting the compaction effect of the road surface.
压路机的振动控制
Vibration control of road rollers
操作过程中，我们主要要控制的是压路机振动的开启和关闭时刻。压路机的振动只有在进行复压（主压）阶段才会开启，而且必须在启动后开振、提前关振，切不可原地开振碾压。
During the operation process, we mainly need to control the opening and closing times of the roller vibration. The vibration of the roller can only be started during the re compaction (main compaction) stage, and it must be started and closed in advance after starting, and cannot be rolled in place.
随着技术进步，许多压路机设置了自动开启和关闭振动的功能，通过一“手动/自动”转换开关完成，当速度达到某一数值时自动开启，当速度低于某一数值时又自动关闭。
With the advancement of technology, many road rollers have been equipped with automatic opening and closing vibration functions, which are completed through a "manual/automatic" conversion switch. When the speed reaches a certain value, it will automatically start and then close again when the speed is below a certain value.
压路机钢轮的喷水量控制
Water spray control of roller steel wheels
经常检查前后两水箱的储水量，及时添加。前后钢轮上的两排喷嘴以及滤网滤芯要经常检查清洗，保持清洁。喷洒水量的大小有操作台上的6个控制档位进行选择，一般情况选择在4档位置。喷洒水量过大过小都不利于压实。过大，加快了沥青混合料的冷却，缩短了碾压时间。过小，沥青混合料由于温度较高容易粘轮。
Regularly check the water storage capacity of the front and rear water tanks and add them in a timely manner. The two rows of nozzles and filter elements on the front and rear steel wheels should be regularly inspected and cleaned to maintain cleanliness. The amount of water sprayed can be selected from six control gears on the control console, usually in the fourth gear position. Spraying too much or too little water is not conducive to compaction. If it is too large, it accelerates the cooling of the asphalt mixture and shortens the rolling time. If it is too small, the asphalt mixture is prone to sticking to the wheel due to high temperature.
压路机的压实技巧
Compaction techniques of road rollers
我们按照施工技术员的施工方案、压实工艺进行碾压，如：碾压速度、压实温度和碾压遍数等。其次，我们必须保证各压路机的同步碾压，做好碾压的一致性。并遵守“紧跟稳压、由外向内、由低往高、先慢后快”的碾压原则。压路机的相邻碾压带应重叠1/3~1/2轮宽。
We roll according to the construction technician's construction plan and compaction process, such as compaction speed, compaction temperature, and number of compaction passes. Secondly, we must ensure synchronous rolling of each roller and ensure consistency in rolling. And adhere to the rolling principle of "closely following the stable pressure, from the outside to the inside, from the low to the high, and from slow to fast". The adjacent rolling strips of the roller should overlap by 1/3-1/2 wheel width.
There are many compaction techniques for road rollers, and it is necessary to constantly explore and strive for excellence in compaction construction in order to achieve better compaction results. For more related content, come to our website Consult and learn more!
