| Abstract: | Excavating pile in bedrock is a construction technology used in pile project of Huangcheng Mansion in Xuzhou. When blowing up the bedrock in this project, a collapse occurred, which caused some difficulties in construction. Considering the actual geologic and constructing conditions, architects managed to set up guard walls to give sustenance to the broken bedrock, hence the influence of the accident was soon eliminated and the project was to be carried out smoothly thereafter. |
