复杂管线敏感区域浅埋暗挖通道施工技术及风险控制

CONSTRUCTION TECHNOLOGY AND RISK CONTROL OF SHALLOW BURIED AND UNDERCUT CHANNELS IN SENSITIVE AREAS OF COMPLEX PIPELINES

随着我国轨道交通建设技术的迅速发展和道路系统的拓宽和优化,城市的地下人行通道使用越来越普遍,逐步代替了人行天桥,形成了市区道路结构的必然趋势。结合深圳市城市轨道交通16号线大运中心站附属暗挖通道工程,详细介绍在城市主干道复杂管线敏感区域浅埋暗挖通道的开挖,通过管幕和管棚超前支护及各种开挖施工技术的应用使暗挖通道施工风险有效控制,确保暗挖通道施工安全。

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.
