Analysis and control of the impact of bridge pile foundation construction on adjacent drainage stations
A case study of a bridge pile foundation project in Fuzhou that caused deformation of adjacent drainage stations was conduc-ted.Based on design and monitoring data,the impact of bridge pile foundation construction on adjacent drainage stations was analyzed,and the causes of deformation were thoroughly analyzed.A targeted optimization plan for pile foundation construction technology was pro-posed.Through analysis,it can be concluded that when using multiple punching drilling machines for the construction of large-diameter cast-in-place piles,the adverse effects of their vibration on surrounding buildings should be considered,and the construction process should be adjusted according to the geological conditions of the site.By strictly controlling the number of impact drilling machines,optimi-zing the stroke of impact drilling,lengthening the steel casing,increasing mud density,and combining rotary drilling technology with punc-hing technology,the impact of pile foundation construction on the drainage station has been effectively reduced,and the safety of the drain-age station has been ensured.
