Abstract:Based on the drainage reconstruction of old urban areas with historical features in Wuhan city, the construction of underground arrow micro-pipe jacking under complex geology was analyzed, the technological principle of micro-pipe jacking technology was introduced, and the construction technology and control measures of micro-pipe jacking technology in urban drainage reconstruction project was expounded. The prevention methods of quicksand and mud gushing are put forward, which effectively solves the shortcomings of traditional slotting drainage pipeline construction, provides reference for similar engineering construction.
