在江河抗洪抢险或施工过程中、均需要在某些特定部位打入大量木桩；待抢险和施工结束后，这些桩体还必须拔出，以免给工程造成隐患。传统的拔桩方法一般是利用杠杆原理，人工将打入土中的柱体撬出；操作中，人员劳动强度大，工作效率低，且极易拔断桩体。ＹＢＺ拔桩器是利用液压直顶强拔原理，将打入平面、坡面土体中的木桩、钢桩、混凝土桩等小型桩体垂直拔起，能够保证柱体完好，可达到重复利用、节约投资之目的。
During the flood control and rescue of the rivers or the construction process, a large number of wooden piles are required to be put into operation in certain specific locations. After the rescue and the construction are over, the piles must be pulled out to avoid any hidden danger to the project. Traditionally, the traditional method of pulling pile is to use lever principle to manually pry out the cylinder which penetrates into the soil. In operation, the labor intensity of the worker is high, the working efficiency is low, and the pile body can be easily pulled off. YBZ pile jacking device is the use of hydraulic straight top strong pull principle, into the plane, slope soil in the pile, pile, concrete piles and other small vertical uplift, to ensure that the cylinder intact, can be reused , Save the purpose of investment.
