Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

A pile breaker, as shown in figure 1, comprises a first conical body 1 and a thickening piece detachably connected to the first conical body 1. The first cone 1 may be made of Q345B steel.

As shown in fig. 1, when the size of the removed pile head is larger than the maximum outer diameter of the first cone 1, the setting of the thickening piece increases the size of the first cone 1, and the thickening piece can be selectively installed according to the size of the pile head to be removed, so that the size of the first cone 1 is changed, the use requirement is met, and the cost is saved; when the size of the pile head to be removed is smaller than the maximum outer diameter of the first cone 1, the pile head can be removed without installing a thickening piece.

As fig. 1, thickening piece sets up thickening cone 11 outside first cone 1 including the cover, set up the connect the through-hole 12 that supplies first cone 1 to penetrate in thickening cone 11, connect the pore wall of through-hole 12 and the cooperation of 1 outer wall of first cone, connect through-hole 12 upper end aperture size promptly and be greater than lower extreme aperture size, after thickening cone 11 covers outside first cone 1, thickening cone 11 up end flushes with 1 up end of first cone, 1 up end of first cone is equipped with the bearing plate 13 that the edge extends to thickening cone 11 outer wall. After the thickening cone 11 is sleeved outside the first cone 1, the bearing plate 13 is placed at the upper ends of the first cone 1 and the thickening cone 11. Thickened cone 11 may also be made of Q345B steel. At this moment, when the thickened cone 11 is detached, the bearing plate 13 is taken down, and the first cone 1 is taken out from the upper end of the thickened cone 11, so that the operation is convenient.

As shown in fig. 1, at this time, the end parts of the first cone 1 and the thickened cone 11 are inserted into the center of the pile head with the flange plate exposed out of the ground, so that the thickened cone 11 is fully contacted with the flange plate, and the axis of the pile breaker is ensured to be vertical to the pile head;

as shown in fig. 1, an auxiliary tubular pile is placed in a hydraulic clamp of the static pile press, and the auxiliary tubular pile is vertically aligned with the upper part of the pile breaker;

as shown in fig. 1, at this time, by utilizing the overall continuity of the pile head flange plate, the vertical pressure and the downward transmission of the tension from inside to outside generated when the static pressure machine applies pressure to the pile breaker are ensured, so that the pile head exposed out of the ground is rapidly crushed, and meanwhile, the integrity of the pile body buried underground is not influenced; at this moment, the bearing plate 13 transmits the extrusion force to the thickening cone 11, the thickening cone 11 and the pile head generate the extrusion force, until the pile head is broken, in the extrusion process, the first cone 1 offsets the reverse extrusion force applied to the thickening cone 11 by the pile head, the thickening cone 11 is favorable for breaking the pile head, in addition, when the static pressure machine applies pressure to the pile breaking device, the vertical pressure is generated, the area of the lower end of the auxiliary tubular pile is consistent with that of the bearing plate 13, and the force of the static pressure machine is convenient to transmit to the thickening cone 11.

And (3) lifting the pressure-applying auxiliary pipe pile, removing the pile breaking device, and moving the static pressure machine to continue the construction of breaking the head of the next pipe pile as shown in the figure 1.

As shown in fig. 1, in order to further stabilize the connection between the first cone 1 and the thickened cone 11, a limiting member is disposed on the first cone 1 for limiting the rotation of the thickened cone 11. The limiting member includes a first opening 14 and a second opening 141, wherein the first opening 14 is disposed on the upper end surface of the first cone 1 and is disposed opposite to the first opening 14, the second opening 141 is disposed on the upper end surface of the thickening cone 11 and is opposite to the first opening 14, the first opening 14 is communicated with the second opening 141, and the limiting member 142 is disposed in the first opening 14 and the second opening 141 of the first cone 1. After the first cone 1 is placed into the thickening cone 11, the thickening cone 11 is rotated or the first cone 1 is rotated to enable the first opening 14 and the second opening 141 to be opposite, at the moment, the limiting block 142 is placed into a groove formed by the first opening 14 and the second opening 141, and the limiting block 142 limits the mutual rotation between the first cone 1 and the thickening cone 11.

As shown in fig. 1, the side of the bearing plate 13 facing the first cone 1 is provided with a prismatic connecting piece 15 extending into the upper end surface of the first cone 1. The provision of the connecting piece 15 reduces the relative movement between the bearing plate 13 and the first cone 1 and the thickened cone 11 when the first cone 1 and the thickened cone 11 are pressed.

As shown in fig. 2 and fig. 3, or, the thickening member includes jack 16 that sets up a plurality of cross sections on the periphery of the outer wall of first cone 1 and is the T-shape, the upper end of first cone 1 is extended out to the one end of each jack 16 and jack 16 extends out first cone 1 outer wall, jack 16 distributes along the outer wall of first cone 1, first cone 1 is outer to have butt contact rod 161 through jack 16 grafting, butt contact rod 161 extends jack 16 from the one end of first cone 1 outer wall, butt contact rod 161 is equipped with the curved surface 162 parallel with first cone 1 outer wall in the side of deviating from first cone 1 outer wall, the clamp plate 17 that extends to butt contact rod 161 outer wall is placed to first cone 1 up end, clamp plate 17 connects through the connecting piece that sets up on first cone 1. At this time, the pressing plate 17 limits the position of each contact rod 161 in the insertion hole 16, and meanwhile, the contact rod 161 extends out of the outer wall of the first cone 1, and a new surface abutting against the pile head is formed on the outermost curved surface 162 of each contact rod 161, which is equivalent to increase the size of the outer wall of the first cone 1, and meets the use requirement.

Referring to fig. 2 and 3, the connecting member includes a plurality of locking bolts 171 threadedly coupled to the pressure plate 17, and each locking bolt 171 is threadedly coupled to the first cone 1 through the pressure plate 17. At this time, after the lock bolt 171 is fastened to the pressure plate 17, the upper end of the lock bolt 171 does not extend out of the upper end surface of the pressure plate 17.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
