Impact Roller Product Introduction
mbd. In high-rise filling roadbed, according to traditional construction methods, the compaction of the roadbed is difficult to meet the specification requirements, and the construction period is long. The experimental results of the construction technology of using impact compactor technology to fill the roadbed on the high-rise fill roadbed are as follows
mbd. (
) According to the test results, the high-rise fill roadbed was compacted by Hawei
After the machine impact
mbd. (
) The compacted area has met the requirements through deflection testing. Compared with the embankment filled with qualified soil sources, there is no obvious difference, and the roadbed performance is good.

The processing method of high-rise fill embankment compactor is to directly use bad soil to fill the embankment on the spot, and fill the high-rise It has been specifically applied on square roadbed and achieved good economic and social benefits. Since soil composition and properties vary from place to place, the application of different soil types in different areas is determined through experiments.

The high energy generated by the impact roller can fully increase the pore pressure of the saturated soil and accelerate the dissipation of water if there are drainage channels. Applying the Hawei impact roller to compact the areas that need to be treated can greatly shorten the consolidation time. The use of impact rollers can compact thick fill layers, so that the efficiency of earth moving equipment can be fully utilized and the construction progress can be improved while ensuring the quality of the project. At the same time, due to the high energy of Hawei's impact compaction equipment, the requirements for the moisture content range of the filler can be appropriately relaxed. Taking advantage of the impact roller's advantages of large force and deep action, the original foundation can be compacted, greatly improving the soil strength of the original foundation and saving costs. Due to the large impact force and deep action depth of the impact roller, it can compensate for the roadbed that has been rolled by conventional compaction equipment, and strengthen and compact the weak links in the compaction process, especially the joints of excavation and filling and filling. The effect of pressure compensation on square road sections is particularly obvious.
