Description

Technical Field

[0001] This utility model relates to the field of pipe pile foundation construction technology, specifically to a segmented pile driver. Background Technology

[0002] A pile driver is a tool used in pile foundation construction. Its main function is to help drive the pile to the design elevation when the clamp of the pile driver is a certain distance from the ground.

[0003] Traditional pile drivers cannot flexibly handle pile driving depths at various elevations. In some pile driving areas, due to design and other reasons, the pile driving depth is too deep, and a single traditional pile driver is unlikely to reach the design elevation. Furthermore, even if extra-long pile drivers are specially made, the excessive pile driving depth results in a large contact area with the clay, leading to excessive resistance and significantly affecting the pile driving effect. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a segmented pile driver to solve the technical problems that existing pile drivers are not applicable when the pile driving depth is too deep and the resistance during pile driving is too great.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a segmented pile driver, including: at least one first pile driver section and a second pile driver section, wherein each of the first pile driver sections is detachably connected end to end; the outer diameter of the second pile driver section is larger than the outer diameter of the first pile driver section, and the second pile driver section is detachably connected to the first pile driver section located at the end, and the second pile driver section is used to impact the pile head.

The segmented pile driver also includes a plurality of connecting members, and the first connecting ears are detachably connected to the second connecting ears or other first connecting ears of the first pile-driving section through the connecting members.

[0008] In some embodiments, the segmented pile driver further includes a pile cap, one end of which is fixedly sleeved on the end of the second pile driver section used to impact the pile head. The inner diameter of the pile cap is larger than the outer diameter of the pile head. When the second pile driver section impacts the pile head, the pile cap can be sleeved over the pile head.

[0009] In some embodiments, the segmented pile driver further includes a buffer pad located inside the pile cap and disposed on the end face of the second pile driver section for impacting the pile head.

[0010] In some embodiments, a plurality of lifting lugs are formed on the outer surface of the first pile-driving section, and the first pile-driving section is connected to the crane through the lifting lugs.

[0011] In some embodiments, the first pile-driving section and the second pile-driving section are both cylindrical structures and are arranged coaxially.

[0012] In some embodiments, the second pile-driving section is a frustum-shaped structure, and the outer diameter of the end connected to the first pile-driving section is smaller than the outer diameter of the end that impacts the pile head.

[0013] In some embodiments, the outer diameter of the first pile-driving section is smaller than the inner diameter of the second pile-driving section, and the second pile-driving section is sleeved with the first pile-driving section.

[0014] In some embodiments, the first pile-driving section is a frustum-shaped structure, with the inner diameter of one end being larger than the outer diameter of the other end, and adjacent first pile-driving sections are nested together.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the technical problems of existing pile drivers being unsuitable and causing excessive resistance during pile driving, this invention provides a segmented pile driver. This segmented pile driver allows for flexible selection of the number of first pile driving sections to assemble the device for different pile driving depths, significantly reducing resistance during pile driving and improving pile driving performance.

[0021] Please see Figure 1 and Figure 2 The segmented pile driver includes at least one first pile driver section 1 and a second pile driver section 2, with each first pile driver section 1 being detachably connected end to end. The outer diameter of the second pile driver section 2 is larger than the outer diameter of the first pile driver section 1, and the second pile driver section 2 is detachably connected to the first pile driver section 1 located at the end. The second pile driver section 2 is used to impact the pile head.

[0022] In actual construction, an appropriate number of first pile-driving sections 1 are selected according to the pile driving depth and connected end to end in sequence. One first pile-driving section 1 at one end is connected to the second pile-driving section, and the first pile-driving section 1 at the other end is connected to the pile driver. The pile driver drives the entire pile driver to move, causing the second pile-driving section 2 to impact the pile head.

[0023] In some embodiments, a plurality of first connecting ears 11 are formed on the outer side of the first pile-feeding section 1, and a plurality of second connecting ears 21 are formed on the outer side of the second pile-feeding section 2. The segmented pile driver also includes a plurality of connecting members 3. The first connecting ears 11 are detachably connected to the second connecting ears 21 or other first connecting ears 11 of the first pile-feeding section 1 through the connecting members 3.

[0024] In a preferred embodiment, the first connecting ears 11 are evenly distributed around the first pile-feeding section 1, and the second connecting ears 21 are also evenly distributed around the second pile-feeding section 2, corresponding to the first connecting ears 11. Furthermore, the distance between the connecting structure of the first connecting ear 11, such as the connecting hole, and its central axis is equal to the distance between the connecting structure of the second connecting ear and its central axis. This ensures that even when the outer diameter of the second pile-feeding section 2 is larger than that of the first pile-feeding section 1, the first connecting ears 11 and the second connecting ears 21 can still fit together.

[0025] In this embodiment, the connector 3 can adopt a bolt and nut mechanism to achieve the effect of easy disassembly and assembly and a firm connection.

[0026] In some embodiments, a plurality of lifting lugs 12 are formed on the outer side of the first pile-driving section 1, and external equipment such as cranes or pile drivers are connected to the first pile-driving section 1 through the lifting lugs 12.

[0027] In some embodiments, both the first pile-driving section 1 and the second pile-driving section 2 are cylindrical structures and are arranged coaxially. The first pile-driving section 1 abuts against the second pile-driving section 2. Although the outer diameter of the first pile-driving section 1 is smaller than the outer diameter of the second pile-driving section 2, it is larger than the inner diameter of the second pile-driving section 2. The first pile-driving section 1 abuts against the second pile-driving section 2.

[0028] In other embodiments, the outer diameter of the first pile-driving section 1 is smaller than the inner diameter of the second pile-driving section 2, and the second pile-driving section 2 is sleeved with the first pile-driving section 1.

[0029] In some embodiments, the first pile-driving section 1 is a frustum-shaped structure, with the inner diameter of one end being larger than the outer diameter of the other end, and two adjacent first pile-driving sections 1 are sleeved together.

[0030] In this embodiment, the second pile-driving section 2 has a frustum-shaped structure, and the outer diameter of the end connected to the first pile-driving section 1 is smaller than the outer diameter of the end that impacts the pile head. That is, the smaller end is connected to the first pile-driving section 1, and the larger end is used to impact the pile head.

[0031] In some embodiments, the segmented pile driver further includes a pile cap 4, one end of which is fixedly sleeved on the end of the second pile driver section 2 that impacts the pile head. Furthermore, the inner diameter of the pile cap 4 is larger than the outer diameter of the pile head. When the second pile driver section 2 impacts the pile head, the pile cap 4 can be sleeved over the pile head, serving as a guide to prevent the pile driver from shifting and to ensure that the pile head is subjected to uniform force and is less likely to be damaged.

[0032] In some embodiments, the segmented pile driver further includes a buffer pad 5 located inside the pile cap 4 and disposed on the end face of the second pile driver section 2 that impacts the pile head. Due to the restraint of the pile cap 4, the buffer pad 5 will not detach from between the pile head and the second pile driver section 2. The buffer pad 5 can be fixed to the end face of the second pile driver section 2 or placed on the pile head, positioned between the end face of the second pile driver section 2 and the pile head during impact.

[0033] In a preferred embodiment, the thickness of the cushioning pad 5 is greater than or equal to 1 cm. The cushioning pad 5 may be made of hardwood.

[0034] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
