Customized centrifugal bucket for silt, gravel and dense sand bored piles construction

Introduction:

In foundation piling construction, drilling buckets are the necessary accessories of drilling rigs when do the bores piling job. For different formations, it is best to choose different drill bucket to achieve the best piling effect. For example, for rock coring piles, core barrel with bullet teeth or core barrel with roller bits will be recommended. For dense soils, rock and complex hard strata, rock drilling bucket will be suggested. However, for water-bearing cohesive soils, clay, silt piles, the construction of China usually choose to use Centrifugal Drilling Bucket, also called Open Bucket. The so-called open type drill bucket is the barrel of the drill bucket can be divided into two parts, it is easier to unload the soil or clay after the piles drilling work each time. 


In the original version of the improvement, we integrated centrifugal bucket and rock drilling bucket, the barrel body can still open, but the bottom of the barrel adopts the same design as the rock drilling bucket. The advantage is that the drilling efficiency is higher than ordinary centrifugal bucket, while at the same time, the cylinder can be opened to facilitate unloading soil and improve the soil unloading efficiency.
