压路机作为道路施工中的主要机械工具,被广泛的应用在各种道路施工中。压实效果是衡量施工效果的一个非常重要的因素。济南压路机租赁厂家今天来讲一个问题--压路机压实效果好不好看几个因素。
As the main mechanical tool in road construction, road roller is widely used in various road construction. Compaction effect is a very important factor to measure the construction effect. Jinan Road Roller Rental Factory will talk about a problem today -- how good the compaction effect of the road roller is.
1,土的含水量对压实过程的影响
1. Influence of soil moisture content on compaction process
在压实过程中,土或材料的含水量对所能达到的密实度起着非常大的作用。在施下现场,用某种压路机碾压含水量过小的土或级配集料,要达到高的压实度是困难的;如土的含水量超过佳值时,要达到较大的压实度同样是困难的。因此,在特殊干旱和特殊潮湿地区,在无法或不能采取适宜措施的情况下,实际施工中往往不得小降低对压实度的要求。
In the process of compaction, the water content of soil or material plays a very important role in achieving the compactness. At the construction site, it is difficult to use a certain roller to roll the soil or graded aggregate with too small water content to achieve high compactness; If the soil moisture content exceeds the optimal value, it is also difficult to achieve a greater degree of compaction. Therefore, in special dry and humid areas, when appropriate measures cannot be taken, the requirements for compactness shall not be reduced slightly in actual construction.
2,击实功对佳含水量和大干密度的影响
2. Impact of compaction work on good moisture content and high dry density
某一种土或路面材料的佳含水量和大干密度是随压实功变化而变化的。对同一种土或同一种级配集料而言,击实功增加时,其佳含水量减小,而大干密度增大。在工地用压路机碾压时,同样是这种规律。
The good moisture content and large dry density of a certain soil or pavement material change with the change of compaction work. For the same soil or the same graded aggregate, when the compaction work increases, the good water content decreases, while the large dry density increases. This is the same rule when rolling with a roller on the construction site.

3,压实机械对压实的影响
3. Impact of compaction machinery on compaction
所用的压实机械对一定含水量下的路基土和路面材料的压实状态有很大的影响。使用轻型压路机只能得到较小的密实度。使用重型压路机可以得到较大的密实度。振动压路机比相同质量的普通光面钢轮压路机的压实效果好得多。不但密实度大,而且有效的压实深度也大(含水量大的粘土除外)。
The compaction machinery used has a great influence on the compaction state of subgrade soil and pavement materials under a certain moisture content. The compactness can only be reduced by using a light roller. The use of heavy rollers can achieve greater compactness. The compaction effect of vibratory roller is much better than that of ordinary smooth steel wheel roller with the same quality. Not only is the compactness large, but also the effective compaction depth is large (except for the clay with large water content).
4,碾压速度对压实的影响
4. Impact of rolling speed on compaction
碾压速度影响振动轮对单位面积内材料的压实时间。碾压速度低时,单位面积内的振动次数比碾压速度高时要多,因而作用在被压材料上的能量,前者多于后者。实际上,传递到被压材料层内的能量与碾压速度成反比。假定使碾压材料层达到规定密实度所需的压实能量不变,则碾压速度加倍时,碾压次的数大致也要加倍。返回搜狐,查看更多
Rolling speed affects the compaction time of materials in unit area of vibrating wheel set. When the rolling speed is low, the number of vibrations per unit area is more than when the rolling speed is high, so the energy acting on the material to be rolled is more than the former. In fact, the energy transferred to the compacted material layer is inversely proportional to the rolling speed. Assuming that the compaction energy required to make the rolled material layer reach the specified compactness remains unchanged, the number of rolling times will roughly double when the rolling speed is doubled.
