| Abstract: | A project in Chongqing is located in the Yangtze River and Jialing River interchange. In the construction of ma-nual bored pile, builders encountered a thick layer of cobbl-estone. The cobblestone col apses seriously, and the retaining wal closely to the gravel is at hanging state, which endangers workers’ safety, thus the holing is a failure. This paper mainly introduces the experience of construction technology of man-ual bored pile of cobblestone which can be used for reference for the similar project experience. |
