The Application of Synchronous Construction Technology of Steel Pipe Column Pile for Deep Foundation Pit Support
In order to solve the construction problems of super-long steel pipe column pile lifting construction and inconsistency between pile top and ground elevation in deep foundation pit support engineering,this paper opti-mizes the construction technologies by adopting the meth-ods of steel pipe column pile splitting deepening,the steel pipe segmental splicing auxiliary platform design,vertical control technology,suspension bar reservation technology,concrete pouring technology,etc,reduces the second entry of mechanical equipment caused by firstly carrying out earthwork excavation and then carrying out the steel pipe column pile construction,which not only shorten the con-struction period,but also save the construction period cost and machinery use cost.It can be used for reference.
