The pile hole of the slide-resistant pile is provided with a round hole and a rectangular hole, wherein the rectangular hole has better stress form, stronger bending and shearing resistance and higher bearing capacity of the pile foundation, so that the rectangular slide-resistant pile is commonly adopted in practical construction.

In the related art, the anti-slide pile hole forming equipment needs to be provided with a supporting device for supporting and stabilizing so as to reduce vibration generated in the drilling process. In the pore-forming process of the slide-resistant pile, the hole is required to be firstly led and then repaired, after the hole is led, the hole is required to be repaired once or several times, and each hole repairing is directly carried out from the mouth part of the pile hole to the bottom.

Moreover, stratum conditions of different positions in the pile hole are not completely consistent, and the situation that one side of the pile hole wall is soft and the other side of the pile hole wall is hard exists, so that the situation that track deflection occurs in the hole repairing process of the anti-slide pile hole forming equipment is unavoidable, and the actual hole forming effect of the pile hole cannot meet the requirement.

For ease of description, upper long slipper 1114, upper short slipper 1124, lower long slipper 2114, and lower short slipper 2124 are collectively referred to as slipper tips; the upper long side inner sleeve 1112, the upper short side inner sleeve 1122, the lower long side inner sleeve 2112, and the lower short side inner sleeve 2122 are collectively referred to as inner sleeves.

For example, the slip boots may be hinged by means of pins, and in order to prevent the pins from rotating or moving, the ends of the pins may be provided with a catch plate, which is inserted into a groove provided on the pins, and then fastened to the slip boots by means of fastening bolts.

The ski boot may, for example, have a support surface and a guide surface disposed at each end of the support surface in the height direction, the guide surface being inclined toward the inner sleeve, such ski-like construction facilitating sliding over uneven stake hole walls to allow continued downhole of the ski-stud hole forming apparatus.

The support surface of the upper support shoe 110 is referred to as an upper support surface 113, the support surface of the upper support shoe 110 is referred to as an upper guide surface 114, the support surface of the lower support shoe 210 is referred to as a lower support surface 214, and the support surface of the lower support shoe 210 is referred to as a lower guide surface 215.

In practical application, the length of the slipper head can be set to be as high as possible (namely, the size in the z-axis direction) on the premise of not interfering with each other and other components, so that when small pits exist on the pile hole, the slipper head can directly cross over, and the downward drilling continuity of the anti-slipper pile pore-forming equipment is ensured.

Example two

Fig. 8 is a flowchart of a deviation rectifying method of a supporting device according to an embodiment of the present application. As shown in fig. 8, an embodiment of the present application further provides a method for correcting a deviation of a supporting device, which is used for controlling the supporting device 10 provided in the first embodiment to correct the deviation, where the method for correcting the deviation includes:

s100, controlling the upper layer supporting shoes on the undermining side of the supporting device to extend to abut against the inner walls of the pile holes, and adjusting the hydraulic cylinders corresponding to the upper layer supporting shoes on the undermining side to a low-pressure state. The hydraulic cylinder in the low pressure state has smaller internal pressure, is similar to a spring, can stretch and contract, and provides pressure larger than the internal pressure when encountering the bulge of the hole wall, so that the hydraulic cylinder can be shortened; when the sinking of pore wall is met, external pressure is less than its internal pressure, and the pneumatic cylinder can extend to the butt pore wall, so, the pneumatic cylinder of "low pressure state" can keep the state of butt pore wall when removing, provides holding power for slide pile pore-forming equipment.

And S200, adjusting the hydraulic cylinder corresponding to the upper layer supporting shoe at the overexcavation side of the supporting device to a floating state or a low-pressure state. Wherein, the "floating state" means that the pressure of the hydraulic cylinder is zero, and the inner sleeve can freely stretch and retract in the outer sleeve.

In this way, the upper shoe 110 receives a reaction force provided by the inner wall of the pile hole at the undercut side, and also changes its length according to the external force.

It should be noted that, when the anti-slide pile hole forming device performs normal hole repairing operation, the hydraulic cylinders of the upper layer supporting shoe 110 (i.e., the upper layer long side hydraulic cylinder 1113 and the upper layer short side hydraulic cylinder 1123) are all in a low pressure state, and the hydraulic cylinders of the upper layer supporting shoe 110 can keep in an original low pressure state so as to reduce deviation correcting actions; alternatively, the hydraulic cylinders corresponding to the overbreak upper layer supporting shoes 110 can be adjusted to a floating state so as to avoid the interference of external force on the overbreak side.

S300, controlling the lower layer support boots on the undermining side of the supporting device to be shortened, and adjusting the hydraulic cylinders corresponding to the lower layer support boots on the undermining side to be in a high-pressure state. The pressure inside the hydraulic cylinder in the "high-pressure state" is high, and the pressure provided by the hole wall is insufficient to change the length of the hydraulic cylinder.

And S400, controlling the lower layer support shoe on the overexcavation side of the supporting device to gradually extend, and adjusting the hydraulic cylinder corresponding to the lower layer support shoe on the overexcavation side to a high-pressure state.

Thus, the lower layer supporting shoe 210 can receive the reaction force provided by the inner wall of the pile hole at the over-digging side and form a deflection force together with the reaction force provided by the inner wall of the pile hole at the under-digging side of the upper layer supporting shoe 110, so that the anti-slide pile hole forming equipment deflects, the deviation rectifying effect is achieved, the hole forming effect of the pile hole is ensured, and the upper layer and the lower layer are cooperatively controlled, so that the deviation rectifying accuracy can be ensured.

In practical application, when the deviation rectifying action is carried out, the anti-slide pile pore-forming equipment can stop downwards drilling, and after the deviation rectifying action is carried out in place, the anti-slide pile pore-forming equipment continues downwards drilling to repair the pore, and gradually reduces the deviation of the pile pore along with the continuous proceeding of the pore repair process so as to realize pore repair and deviation rectifying and improve the pore-forming efficiency.

The respective processing steps (S100 to S400) shown in the embodiment of fig. 8 do not constitute a specific limitation to the correction process. In other embodiments of the present application, the deskewing process may include more or fewer steps than the fig. 8 embodiment, for example, the deskewing process may include some of the steps in the fig. 8 embodiment, or some of the steps in the fig. 8 embodiment may be replaced with steps having the same functions, or some of the steps in the fig. 8 embodiment may be split into multiple steps, or the like.
