压路机运行时的碾压原则您知道是什么吗？为了后面使用该机器更好的进行施工，相关运行的原则就要知道，下面济南压路机出租人员就来讲讲这个问题。
Do you know what the rolling principle is when the roller is running? In order to use the machine for better construction, we need to know the relevant operation principles. Now, the taxi staff of Jinan Road Roller will talk about this problem.
1、压路机压路时要从公路的边沿压起，压实路面逐渐向公路中间移动。前侧的轧辊应具有一定的重叠宽度，双辊式压路机与单轮式压路机的交迭宽度为250~300mm，而三轮式压路机的交叠宽度应为主压轮的二分之一左右。
1. When rolling, the road roller shall lift from the edge of the road, and the compacted road surface shall gradually move towards the middle of the road. The roll at the front side shall have a certain overlap width. The overlap width of the double roll roller and the single wheel roller shall be 250~300mm, while the overlap width of the three wheel roller shall be about half of the main roller.
2、压路机碾压技术：在工作过程中，压路机应该在起动前启动，而内燃发动机应先达到中等速度，再转到高速。当坡面非常陡峭的时候，须先用小型压路机进行预压，然后用重型压路机或压路机进行压实。
2. Rolling technology of road roller: in the working process, the road roller should be started before starting, and the internal combustion engine should reach the medium speed first, then turn to the high speed. When the slope is very steep, a small roller shall be used for pre compaction first, and then a heavy roller or roller shall be used for compaction.
3、在直线上进行压实，压实应遵循“由轻到重、由慢到快、由边到中（曲线段按先内、后外）”的原则。使用1次静压+3-4次震动+1次静压的方法，运行速度以3-6/小时为宜。
3. Compaction shall be carried out on a straight line, following the principle of "from light to heavy, from slow to fast, and from edge to middle (the curve section shall be first inside and then outside)". Use the method of one static pressure+3-4 shocks+1 static pressure, and the operating speed is 3-6 km/h.
4、将压路机尽可能的接近摊铺机，采用先轻后重的加压方式进行压路，以保证混凝土在冷却到小温度之前能满足密实度的要求。在碾碎新的沥青路面时，为了降低路面的起皱和开裂，驾驶员应先把主动轮开到新鲜的混合料场中。保证冲击碾压的速度是恒定的，在热料层上不能随意停顿、转弯，而且起步要慢，以减少压痕。
4. The road roller shall be close to the paver as much as possible, and the road shall be compacted in a light to heavy way to ensure that the concrete can meet the requirements of compactness before it is cooled to a low temperature. When crushing the new asphalt pavement, in order to reduce the wrinkling and cracking of the pavement, the driver should first drive the driving wheel to the fresh mixture yard. Ensure that the speed of impact rolling is constant, do not stop or turn at will on the hot material layer, and start slowly to reduce the indentation.
此外，无论是上坡还是下坡，都应该把压路机的传动轮放在后方。这样可以保证上坡时，后轮能承受斜坡和机械本身的推动力，而前轮在地面上进行初步压缩，从而抵抗来自驱动轮的强大剪切力；下坡时，由于压路机自身重量所带来的冲力由主动轮的刹车所抵消，而只有前车轮碾压后的混合料具有支撑后驱动轮的剪力。
In addition, the driving wheel of the roller should be placed behind both uphill and downhill. This can ensure that the rear wheel can withstand the driving force of the slope and the machine itself when going uphill, while the front wheel is preliminarily compressed on the ground to resist the strong shear force from the driving wheel; When going downhill, the impact brought by the roller's own weight is offset by the brake of the driving wheel, while only the mixture rolled by the front wheel has the shear force supporting the rear driving wheel.
This is the principle of rolling when the road roller is running. I hope to help you. Of course, you should pay attention to the maintenance of machinery and equipment. Come to our website for more information Consult!
