runway control
3.Combined with practical engineering,the author discusses the construction technology and scheme of runway-crossing cast-in-situ box girder of overpass bridge in airport,analyzes and computational checks the design process of bailey truss,and illustrates organization safeguard measure,safety precaution and environmental protection measure of quality management and control,which has the meaning to guide similar engineering construction.
4.According to the successful experiences in the project of the second runway in Pudong Airport of Shanghai,and aimed at every working procedure of the concrete road face,it is discussed how to avoid the quality common faults of the concrete road face,such as the super standard of the level-off degree,contraction crack,nonuniform surface,partial lack of intensity and so on.The effective methods to control the quality common faults of the concrete road face are summed up,which have a certain reference value.
