The construction technology will vary with the change of the construction condition. According to the construction condition of the Coal Wharf in Datang Ningde Power Plant in Fujian province the technology of 野sinking pile by vibration hammer extending the original platform to flat stable pile and drilling hole on the full鄄paving platform冶 is put forward. It successfully solved the drilling platform erection of cast鄄in鄄place rock鄄socketed pile on the maritime shallow coverage layer. The construction period is ahead of schedule and it make a great benefits. Key words 院shallow coverage layer 曰rock鄄socketed p
