| Pipe jacking construction started in Fujian and the coastal areas and promotion of many years, but the large diameter pipe jacking in the past the municipal building in Xiamen did not have much experience in similar projects, coupled with the end of construction of the Shanghai Many geological situation is not clear, resulting in geological conditions in the construction and all kinds of information recorded on the different construction methods, and construction conditions influenced by tides, direct construction faces many difficulties. By Gao-ji seawall construction of raw water pipeline of pipe jacking method will be beneficial to such projects in cities along the coast and the environment in similar geological promotion and use.Gao-ji seawall concentration of raw water pipeline seawall project in the face of tight construction schedule, engineering geology is complex and does not appear to meet many unknown geological, survey and other difficult and under difficult circumstances, through a carefully prepared assiduously, many discussions, to curved pipe jacking construction, and strict implementation of special safety, security, contingency plans to enable the project safe, high quality smooth.In this paper, specification analysis and empirical analysis, systems analysis and other methods, under the conditions in the sea of large diameter water supply pipe jacking construction method is summarized. Based on raw water pipeline set seawall project on the sea jacking, marine and other construction techniques immersed studied in detail. And from the construction monitoring, security monitoring, emergency plans and other aspects of sea conditions in the pipe jacking quality and safety control measures.The topic of underground rock in the sea and lots more for pipe jacking summed up a set of effective methods. Results of pipe jacking in the promotion and use of coastal, for more on similar projects in Xiamen research has important practical significance. |
