Key Techniques Research And Construction On Underground Engineering Of Oriental International Hotel

21st is the century for development of urban underground space building, underground engineering to further development and construction requirements gradually increase, development and utilization of underground space is of extremely important significance, development and utilization of underground space become an inevitable trend. As a theoretical and practical nature subject, underground construction processes, high technical requirements, to technical analysis and reasonable selection of construction plan and identify key technology is the research content.Paper first on underground engineering construction process for analysis, main including pit support nursing, and precipitation, and earthwork excavation, and waterproof engineering and concrete engineering construction of construction method, and type features, and the construction process on underground engineering of effect and importance,, through on the process of theory analysis, for determine technology programme provides based; second, for analysis research on underground engineering construction of Oriental international hotel, the engineering soil more for powder sand, penetration coefficient big, and underground level high containing water rich, Groundwater on engineering construction effect big, in analysis construction process of based Shang, summary out the underground engineering construction technology content; while, using numerical simulation software Modflow on precipitation design, key technology for analysis, and on engineering of tube seal blocking technology for research, proposed improved programme, for engineering construction of accuracy and the Security provides guarantees; last, papers on underground engineering of construction monitoring and management for has analysis, through monitoring content, and The frequency of monitoring and monitoring and early-warning of dynamic management of underground engineering construction in order to ensure the smooth progress of the construction of the project.Research combined with Oriental international hotel, engineering construction practice, systematic analysis of the construction technology of underground works, using software to aid the analysis of relevant content, presented key technologies, develop improvement programmes and the monitoring and management of summarized, you can provide a reference for similar project construction.
