Slurry return prevention device and method for grouting at pile end of tubular pile
The device comprises a protective shell, a permanent magnet and a coil ring, a through hole is formed in the center of the protective shell, the diameter of the through hole is consistent with the inner diameter of the tubular pile, the protective shell is arranged and fixed to the outer extension line of the tubular pile end in a sleeving mode, the upper surface and the lower surface of the protective shell are sealed, and an extension type protruding edge is arranged on the outer edge of the upper surface of the protective shell; the permanent magnets are fixed in the protective shell and comprise outward permanent magnets and inward permanent magnets; the coil ring is fixed between the outward permanent magnet and the inward permanent magnet, the coil ring is wrapped in the protective cover, a plurality of coils are symmetrically arranged on the inner side of the coil ring in series, the coils are connected with a control switch and a power supply through wires, and electromagnetic force is generated by controlling power-on and power-off of the coils, so that the permanent magnets are controlled to move, and slurry is drained to a soil body around the pile end. The grout return prevention device is arranged at the pile end of the tubular pile, so that the grouting amount at the pile end of the tubular pile is evenly distributed, and the grouting effect is good.
本发明涉及一种用于管桩桩端注浆的防返浆装置及方法，它包括保护壳、永磁体和线圈环，保护壳中心开设通孔，通孔直径与管桩内径一致，保护壳套设并固定于管桩桩端外延长线上，保护壳上下表面密封，且上表面外缘设有外延式凸楞；永磁体固定于所述保护壳内，永磁体包括向外永磁体和向内永磁体；线圈环固定于向外永磁体和向内永磁体之间，线圈环包裹于保护罩内，线圈环内侧串联对称布置多个线圈，线圈通过导线与控制开关、电源相连，通过控制线圈的通电和断电来产生电磁力，从而控制永磁体移动，将浆液引流至桩端周围土体。通过在管桩桩端设置该防返浆装置，使得管桩桩端的注浆量分布均匀，注浆效果好。
