BVEM multiple 130kW vibroflotation equipment applied in the construction of Xiamen Xiang'an Airport Project in Fujian Province,China

Since June 2023, 12 sets of BVEM 130kW top feed vibroflotation equipment have been used in the construction of Xiamen Xiang'an International Airport.

The project mainly adopts the vibro compaction construction method to improve the bearing capacity of the foundation, prevent uneven settlement of the foundation, and eliminate liquefaction of the foundation. Our equipment maintains strong applicability and excellent performance under harsh conditions such as high temperatures of 40 degrees Celsius and complex geological formations, effectively ensuring project progress.

Soil improvement

The main goal of most soil improvement techniques used for reducing liquefaction hazards is to avoid large increases in pore water pressure during earthquake shaking. This can be achieved by densification of the soil and/or improvement of its drainage capacity.

Vibroflotation involves the use of a vibrating probe that can penetrate granular soil to depths of over 100 feet. The vibrations of the probe cause the grain structure to collapse thereby densifying the soil surrounding the probe. To treat an area of potentially liquefiable soil, the vibroflot is raised and lowered in a grid pattern. Vibro Replacement (right, HB) is a combination of vibroflotation with a gravel backfill resulting in stone columns, which not only increases the amount of densificton, but provides a degree of reinforcement and a potentially effective means of drainage.

Dynamic Compaction

Densifiction by dynamic compaction is performed by dropping a heavy weight of steel or concrete in a grid pattern from heights of 30 to 100 ft. It provides an economical way of improving soil for mitigation of liquefaction hazards. Local liquefaction can be initiated beneath the drop point making it easier for the sand grains to densify. When the excess porewater pressure from the dynamic loading dissipates, additional densification occurs. As illustrated in the photograph, however, the process is somewhat invasive; the surface of the soil may require shallow compaction with possible addition of granular fill following dynamic compaction.
