It is common to use punching cast-in-place pile or drilling one to embed into rock under the geologic circumstances that silt stratification is thick and supporting course is rock foundation.However,safety issues including cave in and collapse arise in the process of construction.Therefore,breaking through the bottleneck that the precast pile can not cross the boulder and stonefall to realize rock embedment is an issue to needing study in the engineering.Combining the engineering design and actual construction,we adopt different types of piles and pile shoes and realize the embedment of the precast pile in the rock foundation.
