Research on the Construction Control Technology of Pile Foundation in the Urban Rail Transit Protection Area
In response to the impact of pile foundation construction on the surrounding environment,this article makes research on pile foundation construction technology within the scope of urban rail transit protection.Targeted design is carried out through three aspects:survey,design,and equipment preparation;During the drilling construction phase,after precise positioning and measurement,adaptive control of drilling parameters is carried out;During the construction phase of the inner casing,concrete is poured after vibration fixation of the inner casing.The test results show that the settlement amplitude at 15.0 m is controlled within the range of 10.0 mm,the settlement amplitude at 60.0 m is stable below 5.0 mm,and the settlement amplitude at 105.0 m can be ignored.This technology effectively ensures the safety of urban rail transit protected areas.
