Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering piling, in particular to a piling device with anti-tilting function. Background Art

[0002] At present, the traditional piling method is to apply force to the top of the pile body and drive the pile body into the stratum. Since the force application point of the pile body is the top of the pile body, it is easy to cause the reaction force of the pile tip and the top force of the pile body to be not on the same straight line, resulting in the pile body being deflected or damaged. After the pile body is deflected, it is often difficult to correct it and it is difficult to continue piling. Especially for empty piles, it is necessary to use a pile delivery pipe to drive the pile body into a stratum below the ground, or in a geologically uneven stratum, when the pile driving method is to apply force to the top of the pile body, it is more likely to cause the pile body to tilt and become difficult to pile, resulting in greater losses. Therefore, it is necessary to improve the traditional pile structure. Utility Model Content

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Figures 1 to 4 The first embodiment of the anti-tilt piling device of the utility model is shown in FIG. Figure 1 and Figure 2 The anti-tilting piling device of this embodiment comprises: a pile body 1, a piling pipe 2 and a pile shoe 3. The pile body 1 has a central hole 11 arranged along the central axis, the upper end of the central hole 11 is an open structure, and the bottom of the central hole 11 of the pile body 1 has a load-bearing part 12; the piling pipe 2 is in a hollow tubular shape, including a pile pipe upper section 21 located outside the central hole 11 of the pile body 1, a pile pipe lower section 22 located inside the central hole 11 of the pile body 1, and an adapter 23 arranged at the bottom of the pile pipe lower section 22. The pile shoe 3 is arranged at the bottom end of the pile body 1, and the pile shoe 3 has a large end 31 and a small end 32. The large end 31 of the pile shoe 3 is fixedly connected to the lower end of the pile body 1 by bolts 34, and the small end 32 of the pile shoe 3 is in a cone shape, corresponding to the piling hole position, which is conducive to rapid piling.

[0041] During piling, the upper part of the pile pipe upper section 21 of the piling pipe 2 is connected to the pile driver through the connecting part 24, and the adapter part 23 at the bottom of the pile pipe lower section 22 of the piling pipe 2 abuts against the load-bearing part 12 at the bottom of the middle hole 11 of the pile body 1, so as to transmit the piling force of the pile driver to the pile body 1 and the pile shoe 3. The force of the pile driver is transmitted to the load-bearing part 12 at the bottom of the middle hole 11 of the pile body 1 through the adapter part 23 of the piling pipe 2, which reduces the piling force point of the pile body 1, so that the pile body 1 is not easy to tilt, thereby improving the stability of piling.

[0042] like Figure 1 and Figure 2 As shown, a limiting plate 4 is fixedly installed on the opening of the upper end of the middle hole 11 of the pile body 1, and a limiting hole 41 is provided in the center of the limiting plate 4. The limiting hole 41 is used for the pile pipe lower section 22 of the piling pipe 2 to pass through and extend into the middle hole 11 of the pile body 1. An annular cavity is formed between the outer wall of the pile pipe lower section 22 of the piling pipe 2 and the inner wall of the middle hole 11 of the pile body 1. The aperture of the limiting hole 41 is slightly larger than the outer diameter of the piling pipe 2 to prevent the piling pipe 2 from tilting in the middle hole 11 of the pile body 1.

[0043] like Figure 1 , Figure 2 and Figure 3As shown, the large end of the pile shoe 3 is concavely provided with a cavity 33, and a fixing member 6 is fixedly installed in the cavity 33. The fixing member 6 is fixedly connected to one end of the tie rod 5, and the other end of the tie rod 5 passes through the through hole 121 of the load-bearing part 12 of the pile body 1 and the middle hole 11 of the pile body 1 in sequence, and extends outward from the middle hole 11 of the pile body 1. The end of the tie rod 5 extending outward from the middle hole 11 of the pile body 1 is used to connect to the external member on the stratum for fixed connection, so as to transmit the tensile force between the pile body 1 and the external member. The tie rod 5 can be made of some slender rods with good tensile properties such as steel bars, steel strands, carbon fiber rods, or glass fiber rods. Figure 2 The adapter part 23 at the bottom of the lower section 22 of the pile driving pipe 2 has a channel 231 in the middle for the reinforcement 5 to pass through. The reinforcement 5 is pre-fixed and connected to the fixing member 6 in the cavity 33 of the large end 31 of the pile shoe 3, which will not affect the adapter part 23 of the pile driving pipe 2 to drive the load-bearing part 12 of the middle hole 11 of the pile body 1.

[0044] like Figure 3 As shown, a plurality of slurry outlet holes 7 are provided on the side wall of the pile body 1, and the slurry outlet holes 7 are used to connect the middle hole 11 of the pile body 1 with the outside of the side wall of the pile body 1. The slurry outlet holes 7 are obliquely provided, and one end of each slurry outlet hole 7 starts from the inner side wall of the pile body 1, and extends obliquely along the side wall of the pile body 1 and toward the upper end of the pile body 1 to the outer side wall of the pile body 1. When the slurry is injected into the middle hole 11 of the pile body 1, the slurry will flow out of the side wall of the pile body 1 through the slurry outlet holes 7 to increase the frictional resistance between the outer side wall of the pile body 1 and the soil layer.

[0045] like Figure 3 and Figure 4 As shown, the load-bearing part 12 at the bottom of the middle hole 11 of the pile body 1 is in the shape of a ring, the upper surface of the ring is in a horizontal structure, and is perpendicular to the central axis of the pile body 1. The horizontal structure of the load-bearing part 12 and the adapter part 23 of the pile pipe 2 are arranged in parallel with each other, and the through hole 121 arranged in the middle of the load-bearing part 12 is a circular hole for passing the tension bar 5. The axes of the pile pipe 2, the adapter part 23, the pile body 1 and the load-bearing part 12 are all coincident. When the adapter part 23 of the pile pipe 2 abuts against the load-bearing part 12 of the pile body 1, the pile driving force of the pile driver acting on the upper end of the pile pipe 2 is transmitted to the pile body 1 and the pile shoe 3 through the adapter part 23 of the pile pipe 2 and the load-bearing part 12 of the pile body 1, and the pile driving force transmission efficiency of the pile driver is high.

[0046] Figure 5 and Figure 6 The second embodiment of the anti-tilt piling device of the utility model is shown in FIG. Figure 5 and Figure 6The main difference between the anti-tilt piling device of the second embodiment and the anti-tilt piling device of the first embodiment is that the load-bearing part 12 at the bottom of the middle hole 11 of the pile body 1 is composed of four load-bearing blocks 122, which are arranged around the central axis of the pile body 1, and the angle between adjacent load-bearing blocks 122 is 90°. The four load-bearing blocks 122 enclose a through hole 121, and the through hole 121 is used for the reinforcement 5 to pass through. The load-bearing blocks 122 are dispersedly arranged and each is subjected to the pile driving force.

[0047] Figure 7 and Figure 8 The third embodiment of the anti-tilt piling device of the utility model is shown in FIG. Figure 7 and Figure 8 The main difference between the anti-tilt piling device of the third embodiment and the anti-tilt piling device of the first embodiment is that the load-bearing portion 12 at the bottom of the middle hole 11 of the pile body 1 is a load-bearing plate 123, the load-bearing plate 123 is circular, and the load-bearing plate 123 and the pile body 1 are integrally formed. The adapter portion 23 of the piling pipe 2 cooperates with the load-bearing plate 123 of the pile body 1, the contact area is large, and the piling force transmission efficiency is high.

[0048] It should be noted that when the load-bearing portion 12 of the pile body 1 of this embodiment is a load-bearing plate 123, there is no through hole on the load-bearing plate 123 for the reinforcement to pass through, so the reinforcement and the fixing member connected to the reinforcement can be removed.

[0049] Fig. 9 and Fig.10 The fourth embodiment of the anti-tilt piling device of the utility model is shown in FIG. Fig. 9 and Fig.10 The main difference between the anti-tilt pile driving device of the fourth embodiment and the anti-tilt pile driving device of the first embodiment is that the load-bearing portion 12 at the bottom of the middle hole 11 of the pile body 1 is an upward open bell mouth 124, while the adapter portion 23 of the pile driving pipe 2 is a downward closed bell mouth 232, the open bell mouth 124 and the closed bell mouth 232 are arranged in coordination, and the outer side wall of the closed bell mouth 232 at the bottom of the pile driving pipe 2 abuts against the inner side wall of the open bell mouth 124 of the pile body 1, that is, the closed bell mouth 232 of the pile driving pipe 2 is accommodated in the bottom of the open bell mouth 124 of the pile body 1. Therefore, when the pile driving pipe 2 drives the pile body 1, the closed bell mouth 232 of the pile driving pipe 2 is restricted in the open bell mouth 124 of the pile body 1, which is conducive to the pile driving pipe 2 transmitting the pile driving force to the pile body 1 and the pile shoe 3 in the vertical direction, and preventing the pile driving pipe 2 from being deflected and causing the inclination of the pile driving device.

[0050] Fig.11 and Fig.12 The fifth embodiment of the anti-tilt piling device of the utility model is shown in FIG. Fig.11 and Fig.12 The main difference between the anti-tilting piling device of the fifth embodiment and the anti-tilting piling device of the first embodiment is that the load-bearing portion 12 at the bottom of the middle hole 11 of the pile body 1 is an upward convex cone structure 125, and the adapter portion 23 of the piling pipe 2 is a concave cone structure 233, and the convex cone structure 125 and the concave cone structure 233 are arranged in coordination. Specifically, the inner wall of the concave cone structure 233 of the piling pipe 2 abuts against the upper part of the outer wall of the convex cone structure 125 of the pile body 1, that is, the upper tip of the convex cone structure 125 of the pile body 1 is accommodated in the concave cone structure 233 of the piling pipe 2. When the piling pipe 2 drives the pile body 1, the concave cone structure 233 of the piling pipe 2 is restricted outside the convex cone structure 125 of the pile body 1, which is conducive to the piling pipe 2 transmitting the piling force to the pile body 1 and the pile shoe 3 in the vertical direction, and preventing the piling pipe 2 from being deflected and causing the piling device to tilt.

[0051] In the above five embodiments, the lower section of the pile driving pipe is inserted into the bottom of the middle hole of the pile body, which reduces the pile driving force point of the pile body, and the pile body is not easy to tilt during pile driving. In the fourth and fifth embodiments, the adapter part of the pile driving pipe and the load-bearing part of the pile body are in contact with each other by interlocking, so that when the pile driving pipe and the pile body transmit the pile driving force, the pile driving force is always along the central axis of the pile body, and the anti-tilting effect is better.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
