Application of Foundation Pit Excavation and Support Construction Technology in High-rise Building Engineering
This paper takes a high-rise residential building as an example to explore the application of foundation pit excavation technology and high-pressure jet grouting pile support technology.After the completion of earthwork excavation,timely support is needed to prevent the collapse of the free surface.In this project,high-pressure rotary jet pile support technology is selected.The jet pipe is put into the drilling hole,and the high-pressure rotary jet pile machine is connected to spray cement slurry,and the cement slurry can impact and cut the soil at high speed through the rotating nozzle to form cement mixture.At the same time,it can enhance the anti-seepage ability,and create favorable conditions for the safety of foundation pit operation and the construction of the superstructure of high-rise buildings.
