In order to guarantee successful shield construction, the paper carries out bored pile pulling treatment of existing pipe-protecting bridge. According to bad engineering geology conditions and being sensitive to soil deformation of large-diameter drainage pipe, it selects 360°ro-tary machine for pile-pulling construction, and describes construction difficulties, technology comparison and construction process, which has ac-cumulated experience for similar engineering construction.
