| Abstract: | The conditions of the foundation pits of the Lanzhou Olympic Sports Center Project Athletes Apartments and Sports Industry Housing Projects are extremely complicated,such as extremely high groundwater level,a large amount of construction and domestic garbage,and collapsible loess,with a pebble layer as the supporting layer.For this complex stratum,the long spiral pressure grouting pile is finally selected in this project.Through the application research of long spiral pressure grouting piles in complex stratum,the relevant key technical indicators are summarized,and good economic and technical benefits have been obtained,which lays a good foundation for the later research on the application of long spiral pressure grouting pile in complex stratum basis. |
