Trilateral impact rollers have a much greater impact capacity than smaller rollers such as 3-ton rollers, 6-ton rollers, and the compaction impact depth of trilateral impact rollers is unmatched by smaller rollers.
Post-construction settlement and uneven settlement are effectively controlled, and the overall strength of the roadbed can be comprehensively improved to ensure the performance of the road.
Impact rollers - Impact rollers have a unique function of kneading, loosening and mixing compacted surfaces. During the rolling process, the 100mm thick soil particles and soil blocks on the upper surface are crushed according to the rolling angle, which plays the role of horizontal kneading and close penetration of adjacent paving layers. The loose surface layer and the new paving layer will penetrate and mix with each other, the integrity is better after compaction, so it is not easy to crack, but in the process of impact rolling construction will still encounter some small problems, the following is a series of suggestions made by the manufacturer according to some customer questions, if you have any questions, welcome to contact at any time.
The impact roller is pulled by the loader, driving an impact wheel, using the weight of the impact wheel itself and the impact force when moving forward, to crush and compact the cement pavement and roadbed. It was proposed by the South African company Aubrey Berry in the 50s of the 20th century, but it became a mature and practical non-circular rolling impact compactor in the 70s and 80s of the 20th century, and began to be promoted globally in the 90s of the last century.
Some non-professional construction parties receive one-time engineering contracts, because considering that they may no longer be involved in engineering construction in the future, they can consider the rental of impact rollers, which not only saves capital investment, but also does not need to consider the problem of impact rollers after the end of the project.
The impact roller uses non-round wheels to stop the continuous operation of static pressing, kneading and periodic impact on the earth and rock materials along the air, resulting in a violent shock wave, which has the characteristics of downward propagation of seismic waves. Some earthwork materials have the characteristics of effective compaction thickness of 1.5m, which has better compaction effect than the existing vibrating compaction machinery, so that the compacted soil and rock filler is closer to the elastic state.
Therefore, 10 times to complete a complete rolling process, and as we all know, in actual construction operations, it is difficult to achieve accurate coverage of "peak shift", which can increase the number of rolling passes to make up, and at the same time, increasing the number of rolling passes can also shorten the impact length. Therefore, two complete impact rolling processes – 20 passes – became the "standard" requirement for impact rolling construction.
Impact rollers in construction, like some ordinary PPP projects, high-speed passages, expressway construction, earth and rock compaction, garbage compaction, etc., the use of 25kj, 30kj impact rollers can fully meet the design requirements. For construction projects with relatively high construction requirements, such as airports and dams, 32kj impact rollers must be used to meet construction standards.
Impact rolling is the application of irregular pattern roller in compaction technology caused by the momentum and driving mechanical energy closely combined, along the road surface to carry out negative pressure, kneading, impact continuous impact rolling work, produce high amplitude, low number of impact compaction effect, the impact rolling effect, can immediately expand the compaction degree of the underground soil layer, to achieve the purpose of compaction.
