Application Of PHC Piles Gallery Project Outer Tube

In December2008, my Project Department in "outside Pipe gallery project" boldly selected the new technology which use high-strength prestressed pipe pile (PHC) instead of pipe Gallery pillars. It strongly protected the whole project put into operation as scheduled, and achieved good social and economic value.At the same time, the new technology which PHC pile as a pillar in pipe Gallery is individual in the country, it has high scientific value.In this article, through the whole process of the project construction review and analysis of research and discussion on the following issues:(1) introduce on the basic situation of the project and geological exploration process and conclusions.(2) in the implementation of projects, how to uses value engineering theory On selection of design scheme.(3) during the design phase, how to resolve the various problems. How to Selected pile type, how to overcome the horizontal thrust, test pile construction and detection, pile head connection,and so on,to resolve practical problems.(4) detailed the piles total control in the construction stage. From a construction point,to take into account on how to solve engineering problems. Through the pile and vertical position control, drill hole pile foundation.piling,multiple steps to control and to make the successful completion of the project. Understanding quality test on pile foundation and pile testing method.At the same time, reporting to the articles on the current situation of the project. And based on years of experience in project management, presents some of the considerations in the management of large projects.
