Guide: the earliest use of compaction machinery was to build dams, because experience has proved that compacted dams can resist water erosion and infiltration. Early built roads will be uneven due to embankment settlement, which reminds construction engineers that mechanical compaction is necessary to prevent or reduce this

the earliest use of compaction machinery was to build dams, because experience has proved that compacted dams can resist water erosion and infiltration. Early built roads will be uneven due to embankment settlement, which reminds construction engineers that mechanical compaction is necessary to prevent or reduce this settlement and other structural defects

therefore, embankment and road construction have always been the most important industries to apply soil compaction technology

compaction machinery has been following the market demand from drag type to self-propelled type, from rigid compaction to flexible roller, from static compaction to vibratory compaction. Especially since the 1950s, many governments have been committed to recovering from the trauma of World War II, and infrastructure construction has flourished. The requirements for the bearing capacity and service life of various engineering foundations are getting higher and higher, prompting construction experts to have a deeper understanding of compaction technology and compaction machinery. Relatively speaking, vibration compaction machinery with higher price can be widely accepted by the market soon. Driven by the transmission revolution, hydrostatic transmission makes it easy for vibratory rollers to realize power diversion, all wheel drive, all wheel vibration, articulated steering and frequency and amplitude modulation vibration, and various forms of vibratory rollers have emerged. From the towed vibratory roller to the self-propelled all wheel drive single wheel vibratory roller and the double steel wheel vibratory roller, the evolution process of the two main series of vibratory rollers has been carried out in an instant. The single wheel vibratory roller is mainly used for compacting earthwork, and the double steel wheel vibratory roller is mainly used for compacting asphalt pavement

in addition to the above two main series of vibratory rollers, bump vibratory rollers have also been developed for the compaction of clay, hand-held vibratory rollers and vibratory compactors have been developed for the compaction of small projects, and traction slope rollers have been developed for dams and river channel buildings

the recent control revolution enables the roller to realize the degree control of vibration, watering and walking, as well as automatic fault alarm and random compaction detection. A breakthrough has been made in the automatic regulation of the vibration parameters of road rollers. The intelligent road roller with automatic luffing vibration system innovated by BMW, although its innovation cost is expensive, has been widely recognized by engineering contractors. This is because far sighted contractors strive to defeat their competitors with the advantages of technical equipment. Therefore, the annual sales volume of BMW's double drum vibratory roller has increased by 10%

at the dawn of the new century, customers have put forward more personalized requirements for compaction machinery. Brush clips aim at and clamp the remaining hair bundles, and try to use special equipment under a specific construction condition, which is conducive to improving production efficiency and compaction quality, and can save the project cost on the whole. In addition to the oscillation roller, vertical vibration roller and impact roller mentioned above, there are also thin-layer vibratory roller suitable for compacting 25~40mm asphalt pavement, self-propelled slope vibratory roller capable of working on 36 ° slope embankment, groove vibratory roller equipped with remote control device A shoulder vibratory roller that can prevent the collapse of the shoulder and the crushing of the road surface, and a groove backfill vibratory roller equipped with a knife board. There are also some special accessories that can improve the technical performance of the vibratory roller, such as ASC automatic slip control system with a slope grasping capacity of up to 68%, air-cooled supercharged diesel engine adapted to plateau climate, anti rollover and falling object protection device with safety function, automatic luffing vibration control system and central pivot steering mechanism with five steering modes

at present, the countries with relatively developed compaction machinery manufacturing industry are Germany, the United States, Sweden, Japan, China, France, Britain and Russia. Among them, the United States is a major producer of compaction machinery and the largest compaction machinery market in the world, accounting for almost 50% of the western large and medium-sized roller market. According to experts' estimates, the annual sales of compaction machinery (excluding compactors) entering the international market in recent years have exceeded US $1.6 billion, and four multinational companies, BMW, dynapark, Ingersoll Rand and caterpillar, have occupied more than 60% of the international market

at the end of the 20th century, the annual output of road rollers in the world was about 60000, and the annual output of tamping machinery was more than 400000. In recent 10 years, the demand for compaction machinery in the world's major industrial developed countries has tended to be saturated, but the output has not decreased, thanks to the vast market of developing countries. The annual sales of the world's major compaction machinery manufacturing companies, such as BMW and dynapark, have increased by more than 50% in the past 10 years. BMW is the largest manufacturer and exporter of compaction machinery in the world, with an annual output of 25000 sets of various compaction machinery and sales of more than 640million marks
