A pulling-out method of a static pressure pipe pile

The utility model relates to a pulling-out method of a static pressure pipe pile, which firstly removes the residual soil in the static pressure pipe pile; And then inserting the reinforcing steel barinto the static pressure pipe pile; Then injecting slightly expansive cement mortar or grouting material into the static pressure pipe pile, and after the strength reaches the requirement, adopting the shock flushing and pulling-out process to pull out the whole static pressure pipe pile; When the length of the static pressure pipe pile is longer, the pulled-out part can be cut off, and then theremaining part can be pulled out. After all the static pressure pipe piles are pulled out, the remaining virtual holes will be filled. The method is simple and effective, convenient and quick to pullout the pipe pile, and the success rate is high. And the static pressure pipe pile can be recovered and reused. 种静压管桩的拔出方法，先清除静压管桩内的残土；然后将钢筋插入静压管桩内；再向静压管桩内注入微膨胀水泥砂浆或灌浆料，待强度达到要求后，采取震冲拔出工艺进行拉拔，将整根静压管桩拔出；当静压管桩长度较长时，可将拔出部分切断，然后继续拔出
