壓路機作為道路施工中的主要機械工具,被廣泛的應用在各種道路施工中。壓實效果是衡量施工效果的一個非常重要的因素。濟南壓路機租賃廠家今天來講一個問題--壓路機壓實效果好不好看幾個因素。
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,土的含水量對壓實過程的影響
1. Influence of soil moisture content on compaction process
在壓實過程中,土或材料的含水量對所能達到的密實度起著非常大的作用。在施下現(xiàn)場,用某種壓路機碾壓含水量過小的土或級配集料,要達到高的壓實度是困難的;如土的含水量超過佳值時,要達到較大的壓實度同樣是困難的。因此,在特殊干旱和特殊潮濕地區(qū),在無法或不能采取適宜措施的情況下,實際施工中往往不得小降低對壓實度的要求。
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,擊實功對佳含水量和大干密度的影響
2. Impact of compaction work on good moisture content and high dry density
某一種土或路面材料的佳含水量和大干密度是隨壓實功變化而變化的。對同一種土或同一種級配集料而言,擊實功增加時,其佳含水量減小,而大干密度增大。在工地用壓路機碾壓時,同樣是這種規(guī)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,壓實機械對壓實的影響
3. Impact of compaction machinery on compaction
所用的壓實機械對一定含水量下的路基土和路面材料的壓實狀態(tài)有很大的影響。使用輕型壓路機只能得到較小的密實度。使用重型壓路機可以得到較大的密實度。振動壓路機比相同質(zhì)量的普通光面鋼輪壓路機的壓實效果好得多。不但密實度大,而且有效的壓實深度也大(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,碾壓速度對壓實的影響
4. Impact of rolling speed on compaction
碾壓速度影響振動輪對單位面積內(nèi)材料的壓實時間。碾壓速度低時,單位面積內(nèi)的振動次數(shù)比碾壓速度高時要多,因而作用在被壓材料上的能量,前者多于后者。實際上,傳遞到被壓材料層內(nèi)的能量與碾壓速度成反比。假定使碾壓材料層達到規(guī)定密實度所需的壓實能量不變,則碾壓速度加倍時,碾壓次的數(shù)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.
