| Abstract: | The bridge project of the HZMB it uses the steel composite pile foundation. This paper analyzes the adverse weather conditions, hole collapse, equipment failures and other risks in early constructions to supplement, improve and optimize the operating instructions, puts emphasis on process pre-control, improves the proportion of class I that large length and large diameter steel composite pile. It meets the requirements by the pile foundation quality inspection. |
