then after the precast pile 20 is driven into a specified depth, the hydrostatic press can draw back hydraulic oil through the oil pipe connection port 5, at this time, the extended second pile body 2 and third pile body 3 can return to the original length due to the drawing of the hydraulic oil, so that the extended second pile body 2 and third pile body 3 can be conveniently drawn out, after the first pile body 1, the precast pile 20 and the butt joint grooves 1902 at the upper and lower sides of the butt joint cap 1901 are butted, the position can be doubly locked through the butt joint cap 1901, the situation that the pile bodies deviate in the process of moving down can be greatly reduced, in addition, the butt joint grooves 1902 at the upper position are provided with buffer wood pads 1903, the contact surface of the precast pile 20 and the first pile body 1 can be uniformly stressed through the arrangement of the buffer wood pads 1903, the burst and damage probability of the precast pile 20 can be reduced, in addition, the diameter ratio of the first pile body 1, the second pile body 2 and the third pile body 3 of the butt joint cap 1901 is wider, in the process of pressing down, the butt-joint cap 1901 can carry away a larger range of soil, which can effectively avoid the condition that the soil enters gaps of the first pile body 1, the second pile body 2 and the third pile body 3 in the process of stretching and retracting, and the normal lifting is influenced;
before the precast pile 20 is driven into the ground, the orientation seat 2101 can be arranged on an orientation point, the first orientation pile 2104 on the inner side of the rotating seat 2103 and the second orientation pile 2107 on the inner side of the fixing plate 2106 can be driven by extending hands into the operation through groove 2105, so that the orientation seat 2101 can be stably fixed on the outer side of the orientation point, the first pile 1, the second pile 2, the third pile 3 and the outer end of the precast pile 20 are all provided with clamping grooves matched with the orientation block 2108, so that the first pile 1, the second pile 2, the third pile 3 and the precast pile 20 can be positioned by the orientation seat 2101 and the insertion ring 2102 in the process of driving into the ground layer by extending into the inner side of the insertion ring 2102, and the perpendicularity in the soil layer can be effectively ensured by matching with the bidirectional positioning of the connection cap 1901, and if the orientation seat 2101 is driven into the inclined ground, the accessible is rotated seat 2103, makes and is rotated seat 2103 and drives first locating pile 2104 and change the orientation, and this enables directional seat 2101 and still can guarantee the straightness that hangs down that precast pile 20 was squeezed into in the soil layer when the inclined plane, and directional seat 2101 is whole to be the cover body shape in addition, and this grit and the dust that can effectively reduce pile body and precast pile 20 and squeeze into in-process in the soil layer splash.
