| description | The utility model provides a prefabricated assembly type open caisson grouting drag reduction structure which comprises a prefabricated assembly type open caisson formed by splicing pipe pieces in a staggered mode, vertical grouting guide pipes and transverse grouting guide pipes which are arranged in a staggered mode are embedded in the outer sides of the pipe pieces, the vertical grouting guide pipes are communicated with the transverse grouting guide pipes, and the vertical grouting guide pipes between every two adjacent layers of pipe pieces are communicated. A grouting system is further arranged, the grouting system comprises a material storage box, a conveying pump and a slurry conveying pipe, and the slurry conveying pipe is communicated with the vertical grouting guide pipe on the top-layer pipe piece. The grouting guide pipe is simple in structure, grouting can be repeatedly conducted according to the site difficult-to-sink condition, and the technology is simple; the vertical grouting guide pipes an |
