BVEM Vibroflotation Equipment Compaction Piling Driving Machine Used for Soil improvement

Project case : Vibroflotation compaction stone column for foundation treatment of headworks of Dadu River hydropower station

The vibro replacement stone column project of the head hydroproject mainly deals with the foundation treatment of the concrete gate dam, in which the foundation treatment scheme of vibro replacement stone column combined with weighting is adopted for the concrete face rockfill dam on the right bank. In the downstream of the concrete faced rockfill dam foundation, the sand layer is treated with vibro replacement stone column by hole leading construction, which is arranged in square. Vibro replacement stone column is used to treat toe slab, connecting slab and impervious wall.

The bearing capacity of the vibro replacement stone column is not less than 850kpa, and the deformation modulus is not less than 50MPa; the stone material with particle size less than 5mm, content less than 10%, mud content less than 5%, and saturated compressive strength greater than 80MPa is used.

Several sets of BVEM 180-200kW vibroflot equipment be used for this construction.
