The Study And Practice Of Construction Monitor And Control For Large SPan Railway Concrete Continuous Beam Bridge

In civil engineering construction for more than ten years, due to the continuous development of civil transportation engineering transportation business of our country, make our country a large number of sPan continuous beam to present development trend, but how to ensure the safety of continuous beam in the construction process and accuracy, has become a very critical issue. Therefore, the continuous construction monitoring technology of beam has an important role.In the prestressed pipeline grouting construction, grouting quality mainly rely on the experience and occupation ethics construction team to control the pipe grouting pressure, slurry grouting quality and screen time, and at the same time, grouting construction record relies on manual record, grouting construction arbitrarily large, traceability of data reliability is poor, poor. Prestressed pipeline grouting compaction, in after the completion of the bridge, even if the discovery pipeline grouting quality bad recovery is also very difficult. Intelligent tension and grouting equipment, it is these problems have been certain solution.In this Paper, the research object is based on the research of intelligent tension and grouting construction technology of continuous beam cantilever construction monitoring technology, the research not only developed precise intelligent tension and grouting system and equipment, and also makes the practice application for construction monitoring technology of the bridge, thus explained the intelligent tension grouting technology in the continuous beam cantilever construction method has a reliable feasibility.
