Safety Risk Analysis and Control Measures for Pipe Jacking Construction in Complex Strata Undercrossing River
The relocation project of the cross river pipeline for the Shijing River and Xinshiyong River interception hub in Baiyun District,Guangzhou City,adopts practical and effective construction methods for pipe jacking in complex geological environments such as abundant and variable groundwater and quicksand in tidal river sections,hidden foundation treatment residues underground,and numerous surrounding above ground and underground buildings.In response to the complex geological conditions of this type,this paper analyzes the problems that exist during the construction process,mainly focusing on the analysis and solutions of the risks of pipe jacking in and out of the wellbore and pipe jacking construction,the risks of existing buildings(structures)crossing the river,and the risks of shallow soil cover pipe jacking.The impact on the safety of surrounding existing buildings and preventive measures are also discussed.
