History And Development Of Compaction Machinery

Road rollers trampled, rubbed and tamped the soil to treat the foundations of houses and compacted dams and river embankments. Before the mid-19th century, road engineering in the West was dominated by gravel paving, and compaction was mainly carried out by vehicles. It was not until the invention of the stone rolling machine in 1858, which promoted the development of gravel roads, that the use of horse-drawn rollers for compaction work gradually appeared. This is the earliest prototype of the road roller. In 1860, the steam roller appeared in France. Further promote and improve the construction technology and quality of gravel pavement, and speed up the progress. At the beginning of the 20th century, the world recognized the gravel road as the best road at that time, and it was popularized all over the world. The concept of compaction was gradually known, and road rollers also appeared on various road construction sites. In the middle of the 19th century, the invention of the internal combustion engine It has brought great vitality to the development of compaction equipment. The first internal combustion engine-driven road rollers were born in the early 20th century. Then came the tire roller. The sheep foot roller and the smooth roller were produced almost at the same time. People have studied the compaction effect of the static roller. It is believed that increasing the weight of the roller can increase the line pressure of the roller, thereby increasing the pressure. real effect. Therefore, for a long period of time, people have devoted themselves to the development of large-tonnage road rollers. The largest tire rollers once weighed more than 200 tons. However, during this period, the main changes in road rollers were the improvement of body power and appearance.
