The wood pile has the advantages of natural materials, good tensile strength, compression strength, bending resistance and shear strength, low site requirement for construction, small construction machinery, simple construction process and obvious advantages in construction in soft soil areas.

The main construction mode of the existing wood pile construction is as follows: firstly, excavating to the designed ground, then manually positioning pile positions root by root, and finally, adopting machines such as an excavator and the like to press the wood piles into the soil to finish piling. However, the construction mode has lower efficiency and larger error, and has certain requirements on construction sites. The construction will be difficult when the wood pile construction encounters the following conditions: (1) When the water level of the river channel is higher, the lateral impact of water flow on the wood pile makes the wood pile difficult to position, and a cofferdam is required to be arranged at all times to ensure dry construction or to wait for construction after the water level is reduced, so that the construction progress is definitely greatly influenced, and working hours are consumed; (2) When the soft soil to be treated is deeper and the hard soil layers such as the field surface layer filling soil are thicker, the resistance of the wood pile penetrating through the upper hard soil layer is obviously increased, so that the pile sinking is difficult. Because the strength of the wood pile is not high, if the wood pile is pressed by large-scale machinery with large pressure, the wood pile is easy to damage, deform and even collapse; if the pile sinking mode is adopted after the upper hard soil layer is cleared, the workload of excavating and backfilling earthwork is increased, and meanwhile, a corresponding supporting structure is also needed for excavating a deep foundation pit in a soft soil area so as to keep the state of the foundation pit.

In this regard, the present application proposes a pile sinking device for a pile, in which a pile sinking pipe 100 is sleeved on the outer side of the pile to resist the lateral pressure of the soil, and a conical pile head 200 is disposed at the lower end of the pile sinking pipe 100, and the pile head 200 is inserted into the soil and bears the main pile sinking pressure, so as to reduce the damage of the pile 600 in the pile sinking process, and the pile sinking pipe 100 is drawn out after the pile sinking is completed, so that the pile 600 is sunk to the target depth. In addition, this application has still set up pile sinking positioner 300, leads pile sinking pipe 100 through spacing pipe 310 wherein, is equipped with two-layer locating layer 330 at least moreover, restricts pile sinking pipe 100's straightness that hangs down through spacing pipe 310 in each locating layer 330, realizes the location of pile sinking position, promotes pile sinking precision.

Pile sinking pipe 100 is a steel pipe having good structural strength and rigidity, and is open at both ends, and a wooden pile 600 is accommodated in pile sinking pipe 100. The lower end of the pile sinking pipe 100 is movably connected with a conical pile head 200, and the upper end of the pile sinking pipe 100 is connected with external pressing equipment, wherein the pressing equipment refers to a static pile machine, a pile driver or other power equipment capable of applying acting force to a pile body to realize pile sinking. Driven by the pressing device, pile sinking pipe 100 transmits the acting force to pile head 200, and pile head 200 is inserted into the soil body and sinking is performed. In the pipe sinking process, acting force is mainly borne by pile sinking pipe 100 and pile head 200, the pile sinking pipe 100 and pile head 200 protect and convey a wooden pile 600 to the pile sinking depth, and then the pile sinking pipe 100 is pulled out, so that the wooden pile 600 completes pile sinking work.

Further, a lifting hole 110 is formed at the upper end of the pile sinking pipe 100, and the pile sinking pipe 100 can be lifted through the lifting hole 110, so that the pile sinking pipe 100 is pulled out of the soil body through the crane.

Further, the pile driving device of the present wood pile further comprises a pile cap 400 having an outer diameter larger than an inner diameter of the pile driving pipe 100, so that the pile cap 400 does not fall into the interior of the pile driving pipe 100.

The pushing member 500 specifically includes a connecting pipe 510 and a pressing plate 520, the connecting pipe 510 is used for connecting each pressing plate 520, the pressing plate 520 is used for contacting with the top end of the stake 600, and the connecting pipe 510 and the pressing plate 520 are detachably connected, so that the number of the connecting pipes 510 and the pressing plate 520 can be increased according to the pushing depth, the whole length of the pushing member 500 can be changed by connecting a plurality of connecting pipes 510, and the pushing member is suitable for more use scenes. Specifically, the pushing member 500 is further provided with a pressure sensor for detecting the pushing pressure, so as to prevent the damage to the stake 600 caused by the excessive pushing pressure.

Pile sinking positioning device 300 comprises a plurality of limiting pipes 310 and a plurality of connecting pieces 320, and referring to fig. 4, connecting holes 321 are formed in two ends of each connecting piece 320, and the connecting holes 321 are sleeved on the outer sides of the limiting pipes 310, so that connection between the limiting pipes 310 and the connecting pieces 320 is achieved. In order to prevent the spacing tube 310 from being separated from the connection hole 321 of the connector 320, both ends of the spacing tube 310 are provided with spacing rings 311, so that the connector 320 is limited between the two spacing rings 311. Pile sinking pipe 100 passes through the inner side of limiting pipe 310, and the position of pile sinking pipe 100 is limited by limiting pipe 310.

Referring to fig. 5, the connection mode of the limiting tube 310 and the connector 320 may be a triangular unit formed by three limiting tubes 310 and three connectors 320 together, or a distance unit formed by four limiting tubes 310 and five connectors 320 together, or may be a unit formed by splicing together other shapes.
