The key technology of the construction of bored pile occluding cement soil mixing pile in deep foundation pit enclosure
The development and utilization of underground space puts forward higher requirements for foundation pit engineering,especially the emergence of deep foundation pit.Due to the uncertainty of engineering and the complexity of geotechnical engineering,problems such as enclosure safety and deformation stability are prone to occur.Combined support structure can be adopted to improve the stability of foundation pit.For this reason,the paper takes bored pile occluding cement soil mixing pile as an example,briefly analyzes the action mechanism of composite pile,and puts forward the key construction technology combined with the actual project case,so as to provide reference for related workers.
