The invention relates to the technical field of pile pitching boats, and discloses a back-silting prevention device and a pile pitching boat. The back silting prevention device comprises a valve body, the valve body is fixedly arranged at the bottom end of the pile body, a containing space extending in the length direction of the valve body is formed in the inner side of the valve body, and the axis of the containing space is coaxial with the axis of the pile body; the valve core is movably arranged in the accommodating space; and the stamping device is used for selectively flushing water with pressure into the end, far away from the pile body, of the valve element so as to drive the valve element to move in the direction far away from the stamping device, so that the valve element is separated from the valve body. The pile pitching ship has the beneficial effects that the phenomenon that sludge flows back into the pile body to block the pile body in the pulling and installing processes of the pile body is avoided, pulling and re-fixing of the pile body are not affected, and the working efficiency of the pile pitching ship is not affected, so that the working efficiency of the pile pitching ship is high.

    本发明涉及插桩船技术领域,公开了一种防回淤装置及插桩船。防回淤装置包括阀体,其固定设置在所述桩体的底端,且所述阀体内侧形成有沿其长度方向延伸的容纳空间,所述容纳空间的轴线与所述桩体的轴线同轴;阀芯,其活动设置在所述容纳空间内;冲压装置,其用于选择性地向所述阀芯上远离所述桩体的一端冲入具有压力的水,以驱动所述阀芯向远离所述冲压装置的方向移动,以使所述阀芯与所述阀体分离。有益效果:在桩体的拔起及安装过程中均不会出现淤泥回流至桩体内而造成桩体的堵塞,不会影响桩体的拔出及再次固定,也就不会影响插桩船的工作效率,以使插桩船的工作效率较高。
