| Abstract: | Taking the technological test pile of diameter 3.8-m cast-in-site pile and the practical construction of Jiashao Bridge as the background,and through the analysis of construction efficiency,the article determines and checkouts the key parameters of the key equipment and the rationality of forced conditions for the equipment using quantity defined by the bid and tender,and validates the rationality required for the construction period.At the same time,the article analyzes the practical construction efficiency of cast-in-site pile to understand the working performances of various large-diameter drilling machines able to be referred for the similar projects. |
