The Research And Application In Pit Support Of The Micro-steel Pipe Pile

With the construction of the constantly expanding the scale of development, pit support in a large number of projects, and become a project must address major issues, in particular micro-steel pipe pile under the conditions of the design and construction is gaining more and more attention. However, due to micro-pipe in the foundation piles supporting the application of the relatively short history, one of its construction technology, and the deformation of carrying capacity and other aspects have not yet fully understood, nor a mature theory, there is a need for micro - Steel pipe pile for further study to determine the economic reasonable, safe and feasible the design and construction technology.The main research achievements of this paper as following:1 .Through theory and practice, analysis and micro-pipe into a pile of force, design and construction methods, combined with on-site practice theory, the mechanism and the lack of a systematic analysis of the study.2. When the micro-level steel pipe pile under load (lateral earth pressure), the pit can be used as a means of support, more applications. In this paper, micro-steel pipe pile on the performance of the force to do a more detailed analysis, in theory, proved that a miniature steel pipe pile specific occasions in the value and advantages.3.Finally,Shaoguan small bar with the technological transformation of production workshop example, the use summed up the design and method of calculating the support of the foundation for a complete design and construction, the facts show that the design and construction technology in the Specific occasions under the support of a very good role in guiding and achieved satisfactory results.
