| Abstract:The paper presents a post pressure grouting construction case in Wuhan. According to the complicated geological conditions with thick slag and pebble layers, by the analysis and comparison of several construction schemes, rotary drilling was selected with optimized high quality mud to satisfy the requirements of engineering quality and construction progress. The construction technologies and the technical measures of rotary drilling were summed up to be reference to the similar projects. |
