CONSTRUCTION TECHNOLOGY AND RISK CONTROL OF SHALLOW BURIED AND UNDERCUT CHANNELS IN SENSITIVE AREAS OF COMPLEX PIPELINES
With the rapid development of China's rail transit construction technology and the widening and optimization of road system,the use of urban underground pedestrian passage is becoming more and more common,gradually replacing the pedestrian bridge,forming an inevitable trend of urban road structure.Combined with the underground tunnel project attached to Dayun Central Station of Shenzhen Urban Rail Transit Line 16,the excavation of shallow buried underground tunnel in the sensitive area of complex pipeline of urban main road is introduced in detail.The construction risk of underground tunnel can be effectively controlled through the advance support of pipe curtain and pipe shed and the application of various excavation construction technologies to ensure the construction safety of underground tunnel.
