Study on Technical System of Construction Safety at Lujiang Station of Guangzhou Subway

Urban subway engineering bores through urban business districts and dense residential area. Construction accident will be likely to generate severe impact on ground environment, and even to cause disasters like ground collapse. The construction safety technology of urban subway project is studied. The implementation details of concrete items, such as maintenance pole deforming, land movement, stress situation of bracing structure, groundwater level, underground pipeline sedimentation, displacement monitoring, and especially the monitoring of round-trip line construction process are probed into. The system of construction safety is also explored. Safety technology at construction field and safety in construction technology are analyzed in depth. The safety measures at various construction fields such as foundation ditch excavation, chamber drilling and working high above the ground, and various construction technology such as personnel digging, blasting, modeling in concrete, steel bracing installation and waterproof layer plastering have been defined. The system of construction safety and management measure has been set up at last. All above have been studied combining with construction practice.
