The Support Schemes And Construction Management Of Deep Foundation

With the rapid economic development and effective planning of land resources, deep basement is more common in deep excavation support, support aspects of construction management technology has become a trend, for the processing of the complex topography, water quality and a variety of constraints surrounding structures, the size of earthwork, underground lines and other various strike, how to select the most reasonable and most fair deep excavation, construction technology change the way support, scientific, orderly, safe and great operating efficiency hazard foundation trench is to ensure that the construction of a prerequisite for success. Deep excavation design and reduce the guarantee to build, optimization methods in the context of excavation safety engineering costs and improve the competitiveness of construction companies, in order to maximize profits, to the community to create greater value.Examples Shanghai Mandarine large deep excavation project analysis, from the deep pit definition, features a brief description of the deep foundation pit support, support design, with the theory and related specifications, based on a comprehensive survey achievements, literature, combined with experience in the construction project has been to determine the technical parameters related supporting structure system to optimize the design. First construction crane engineering aspects of the use of reverse construction principles, with the design of the crane accounting; Secondly, the complicated geological conditions drop cloth works well water began to precipitation pipe optimization; and finally, for support, support for dynamic information monitoring. Combined with engineering examples, from the construction process, design methods, construction quality control for security and economic impact of pit cost aspects, draw reasonable construction process and summarizes the construction control requirements.Combined with the main factors affecting the safety of excavation analysis: support, support the design, construction crane Reversed precipitation engineering and dynamic monitoring of several aspects of the information in detail, combined with practical engineering experience, the article in a "safe conclusive, economic justice, skills first, to facilitate start " principle, concluded a concrete support piles and reinforced concrete supports, and three reinforced concrete trestle construction plans Shanghai name capital projects within the allowable range for adjacent pipeline excavation, providing ample space for the construction, Rainfall for small caliber optimization and control measures to reduce the economic costs, timely tracking dynamic monitoring information, improve work efficiency and ensure the security and excavation pit working hours, and the formation of a limited set of circumstances geographical environment construction experience of similar construction Foundation also played a reference value.
