Description

Technical Field

[0001] This application relates to the field of foundation settlement prevention technology, and in particular to a bamboo-joint pile catch rod and construction method. Background Technology

[0002] Bamboo-joint piles are prestressed concrete piles with annular cross-sections featuring equally spaced bamboo-joint (ring-shaped) protrusions along the axial direction. They apply biomimetic engineering to building construction. Due to the varying sizes of the outer surface of the bamboo-joint pile, it can form a relatively stable interlocking connection with the soil after installation, thereby greatly improving the bearing capacity of the foundation and effectively preventing foundation settlement.

[0003] Currently, bamboo-joint piles are installed by assembling them section by section. After the first section is completed, subsequent sections are usually spliced ​​together. Adjacent sections are typically connected by welding. However, welding requires skilled welders and is highly susceptible to human error. If the weld is not strong, the connection between adjacent sections can easily break when the pile is under tension after construction, significantly reducing the tensile bearing capacity of the bamboo-joint pile. Furthermore, if the weld position is misaligned or local cracks occur during pile driving, the connection between adjacent sections needs to be destructively removed, resulting in high labor intensity.

[0004] To facilitate the removal of two connected direct piles. Quick connection and removal. Summary of the Invention

[0005] To facilitate the rapid splicing of adjacent bamboo-joint piles by construction workers, improve construction efficiency, and enable quick and convenient disconnection of adjacent piles when local cracking occurs during pile driving, thereby increasing the construction error tolerance rate, this application provides a bamboo-joint pile grab bar and construction method.

[0006] This application provides a bamboo-joint pile anchor and construction method, which adopts the following technical solution:

[0007] In a first aspect, this application provides a bamboo-joint pile grab rod, including a pile body, a plurality of connecting columns disposed on one side of the pile body, a plurality of clamping plate groups disposed on the other side of the pile body and corresponding to the plurality of connecting columns, and a telescopic locking mechanism disposed between the connecting columns and the clamping plate groups on adjacent pile bodies for driving the connecting columns to extend outward of the pile body and connecting to the corresponding clamping plate groups. A plurality of connecting holes adapted to the connecting columns are opened on one side of the pile body, and the connecting columns are located in the connecting holes.

[0008] The card plate assembly includes two symmetrically arranged card plates. The pile body has multiple locking holes on the side away from the connecting column. The card plate assembly is located in the locking holes, and the multiple locking holes correspond one-to-one with the multiple connecting holes. The pile body also has a sliding groove on the side away from the connecting column. The sliding groove communicates with the locking holes, and the card plate can slide within the sliding groove. An unlocking mechanism is also provided between the multiple card plate assemblies to drive the two card plates in each card plate assembly to separate from each other.

[0009] By adopting the above technical solution, when construction workers need to splice bamboo-joint piles, they first lift the pile to be spliced, then align the multiple locking holes with the corresponding connection holes, and then use the telescopic locking mechanism to drive multiple connecting columns to extend from the connection holes and insert them into the locking holes. Next, the telescopic locking mechanism is used again to lock the connecting columns to the clamping plate assembly, thus achieving a quick connection between two adjacent bamboo-joint piles. If an emergency occurs during pile driving, such as local cracking, construction workers can quickly release the locking state of the telescopic locking mechanism through the unlocking mechanism, thereby quickly disconnecting the connection between the two bamboo-joint piles. When splicing bamboo-joint piles, the telescopic locking mechanism enables a quick connection between two adjacent bamboo-joint piles. The operation is simple and convenient, requiring no strong welding skills from construction workers, and is less susceptible to human error, improving the construction error tolerance rate. The connection is firm and reliable, making it less prone to breakage at the connection between adjacent bamboo-joint piles when the pile top is under tension. Furthermore, if local cracking occurs at the connection during pile driving, the connection between adjacent piles can be quickly disconnected.

[0010] Optionally, the telescopic locking mechanism includes multiple drive screws that are threadedly connected to the side of multiple connecting columns near the pile body, a support plate fixedly sleeved on the side of the drive screws away from the connecting columns, a linkage assembly disposed between the multiple drive screws for driving the multiple drive screws to rotate synchronously, a guide member disposed between the connecting column and the pile body for guiding the movement of the connecting column and restricting rotation, and a snap-fit ​​assembly disposed between the connecting column and the corresponding snap-fit ​​plate group of the adjacent pile body for fixing the connecting column and the snap-fit ​​plate group.

[0011] The drive screw is located inside the connecting hole, and a support groove is also provided inside the pile body. The support groove is connected to the connecting hole, and the support plate is located inside the support groove and is rotatably connected to the support groove.

[0012] By adopting the above technical solution, when connecting two piles through the telescopic locking mechanism, firstly, the linkage component synchronously drives multiple drive screws to rotate. Then, under the guidance and limiting action of the guide component, the drive screws drive multiple connecting columns to extend out of the connecting holes and insert into the locking holes. Subsequently, the snap-fit ​​component locks the corresponding connecting columns with the two snap-fit ​​plates in the snap-fit ​​plate group, thus realizing the connection between two adjacent piles. The linkage mechanism can synchronously control the extension and retraction of multiple connecting columns, making the operation of construction personnel more efficient and convenient.

[0013] Optionally, the linkage assembly includes multiple drive gears respectively fixedly sleeved on one end of multiple drive screws, a drive gear ring rotatably connected to the pile body, a first bevel gear fixedly sleeved on the outer wall of the drive gear ring, a control rod rotatably connected to the pile body, and a second bevel gear fixedly sleeved on one end of the control rod.

[0014] The drive gear ring meshes with multiple drive gears, the first bevel gear and the second bevel gear mesh with each other, and the control rod passes through the pile body on the side away from the second bevel gear and is located on the outside of the pile body.

[0015] By adopting the above technical solution, when multiple drive screws are driven to rotate synchronously through the linkage component, the construction personnel first rotate the control rod, which drives the second bevel gear to rotate. The second bevel gear drives the first bevel gear and the drive gear ring to rotate. Then, the drive gear ring synchronously drives multiple drive gears to rotate, and the multiple drive gears can drive multiple drive screws to rotate synchronously, thereby realizing the synchronous movement of multiple connecting columns.

[0016] Optionally, the snap-fit ​​assembly includes a connecting block fixedly sleeved on the end of the connecting post away from the driving screw, two snap-fit ​​blocks respectively fixed in the same snap-fit ​​plate group with the two snap-fit ​​plates close to each other, multiple springs respectively fixed on the two snap-fit ​​blocks away from each other, and a limiting member disposed between the snap-fit ​​plate and the pile body to prevent the snap-fit ​​plate from easily disengaging from the sliding groove; the spring is always in a compressed state.

[0017] By adopting the above technical solution, when fixing the connecting column using the snap-fit ​​assembly, the two snap-fit ​​plates are first separated by the unlocking mechanism, which further compresses the spring. Then, the connecting column moves the connecting block downwards. After the connecting block is fully inserted into the locking hole, the construction personnel restore the unlocking mechanism to its initial state. The two snap-fit ​​plates can then move towards each other under the action of the spring and abut against the top of the connecting block, thereby fixing the connecting block into the locking hole and thus fixing the connecting column.

[0018] Optionally, the connecting block is shaped like a frustum, and the cross-section of the connecting block gradually decreases from top to bottom. The side of the two blocks in the same card group that are close to each other is set with an inclined surface, and the inclined surface is inclined from top to bottom.

[0019] By adopting the above technical solution, the truncated cone-shaped setting with the inclined surface of the locking block allows the construction personnel to move the two locking plates and the locking blocks away from each other when the connecting block enters the locking hole without operating the unlocking component. The connecting block can move the two locking blocks and the two locking plates away from the connecting block by the cooperation of the truncated cone and the inclined surface, making it more convenient for the construction personnel to fix the connecting column.

[0020] Optionally, the limiting member is a limiting block fixed on one side of the snap-fit ​​plate, a limiting groove is formed in the pile body, the limiting groove is connected to the sliding groove, and the limiting block slides within the limiting groove.

[0021] By adopting the above technical solution, the limiting block makes it difficult for the snap-fit ​​plate to disengage from the sliding groove under the action of the spring, thereby improving the stability of the snap-fit ​​assembly.

[0022] Optionally, the guide is a guide bar fixed to one side of the connecting column along its length, and the pile body has a guide groove, in which the guide bar slides.

[0023] By adopting the above technical solution, the guide bar can restrict the rotation of the connecting column, so that the connecting column can only move along the length direction of the pile body, thereby guiding and restricting the movement of the connecting column. Moreover, the guide bar has a simple structure and high strength.

[0024] Optionally, the unlocking mechanism includes multiple rotating shafts rotatably connected to the pile body, a drive block fixedly sleeved on the rotating shaft, and a drive assembly disposed between the multiple rotating shafts for controlling the synchronous rotation of the multiple rotating shafts; the cross-section of the drive block is elliptical, and the drive block abuts against two snap-fit ​​plates in the same snap-fit ​​plate group simultaneously.

[0025] By adopting the above technical solution, when the connecting column is fixed by the telescopic locking mechanism, the short axis of the ellipse abuts against the side of the two snap-fit ​​plates in the same snap-fit ​​plate group that are close to each other. When the unlocking mechanism drives the two snap-fit ​​plates in the multiple snap-fit ​​plate groups to separate from each other, the drive component first drives multiple rotating shafts to rotate synchronously. Then the rotating shafts drive the drive block to rotate. When the long axis of the ellipse abuts against the side of the two snap-fit ​​plates in the same snap-fit ​​plate group that are close to each other, the long axis of the ellipse of the drive block can drive the two snap-fit ​​plates in the same snap-fit ​​plate group to separate from each other, thereby releasing the telescopic locking mechanism from fixing the connecting column.

[0026] Optionally, the drive assembly includes multiple transmission gears respectively fixedly sleeved on multiple rotating shafts, a transmission gear ring rotatably connected to the pile body, a third bevel gear fixedly sleeved on the outer wall of the transmission gear ring, a drive rod rotatably connected to the pile body, a fourth bevel gear fixedly sleeved on one end of the drive rod and a knob, a first limiting rod fixedly sleeved on the knob, and two second limiting rods fixedly sleeved on the pile body.

[0027] The transmission gear ring meshes with multiple transmission gears, the third bevel gear and the fourth bevel gear mesh with each other, the drive rod passes through the pile body on the side away from the fourth bevel gear and is located on the outside of the pile body, a storage groove is opened on the outside of the pile body, the storage groove is a sinking groove, the knob, the first limiting rod and the second limiting rod are all located in the storage groove, and the first limiting rod is located between the two second limiting rods.

[0028] By adopting the above technical solution, when the drive assembly synchronously drives multiple rotating shafts, the operator first rotates a knob, which drives the drive rod to rotate. The drive rod then drives the third and fourth bevel gears to rotate. Next, the third bevel gear drives the transmission gear ring to rotate, which in turn drives multiple transmission gears to rotate synchronously. These multiple transmission gears then drive multiple rotating shafts to rotate synchronously. Simultaneously, the first and second limit rods control the rotation angle of the drive block, thereby controlling the contact state between the major or minor axis of the elliptical drive block and two locking plates in the same locking plate group. That is, when the first limit rod contacts one of the second limit rods, the major axis of the elliptical drive block contacts two locking plates in the same locking plate group; when the first limit rod contacts the other second limit rod, the minor axis of the elliptical drive block contacts two locking plates in the same locking plate group. This allows the operator to precisely control the state of the drive block, facilitating the operation of the unlocking mechanism.

[0029] Secondly, this application also provides a construction method for a bamboo-joint pile grab rod, applicable to one of the bamboo-joint pile grab rods mentioned above, and the construction steps are as follows:

[0030] S1. Clear the foundation, mark and mark the lines, and measure and locate the position;

[0031] S2. Weld the pile tip to the bottom of the first bamboo-joint pile;

[0032] S3. Connect the bamboo-joint piles to the pile driver and drive the bamboo-joint piles into the foundation using the pile driver;

[0033] S4. Lift the next section of bamboo pile using a pile driver and align the multiple locking holes with the multiple corresponding connecting holes;

[0034] S5. Multiple connecting columns are driven to extend from the connecting holes through the telescopic locking mechanism and inserted into the locking holes. The connecting columns and the card plate group are locked again through the telescopic locking mechanism to realize the pile connection.

[0035] S6. Repeat steps S3-S5 until the overall driving depth of the bamboo-joint piles meets the construction requirements.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. When splicing bamboo-joint piles, the telescopic locking mechanism can quickly connect two adjacent bamboo-joint piles. The operation is simple and convenient, requiring no strong welding skills from the construction personnel. It is less affected by human factors, improves the construction error tolerance, and the connection is firm and reliable. When the pile top is under tension, the connection between two adjacent bamboo-joint piles is not easy to break. Moreover, if local cracks or other phenomena occur at the connection of the pile body during the pile driving process, the connection between adjacent pile bodies can be quickly disconnected.

[0038] 2. The linkage mechanism in the telescopic locking mechanism can simultaneously control the extension and retraction of multiple connecting columns, making the operation more efficient and convenient for construction personnel;

[0039] 3. The truncated cone-shaped setting of the snap-fit ​​assembly has a beveled surface that matches the snap-fit ​​block. When the connecting block enters the locking hole, the construction personnel do not need to operate the unlocking assembly to separate the two snap-fit ​​plates from each other. With the cooperation of the truncated cone and the beveled surface, the connecting block can move the two snap-fit ​​blocks and the two snap-fit ​​plates to the side away from the connecting block, which makes it more convenient for the construction personnel to fix the connecting column.

[0040] 4. The limiting block prevents the snap-fit ​​plate from dislodging from the sliding groove under the action of the spring, thereby improving the stability of the snap-fit ​​assembly;

[0041] 5. When the major axis of the ellipse abuts against the side of the two snap-fit ​​plates in the same snap-fit ​​plate group, the major axis of the ellipse of the drive block can drive the two snap-fit ​​plates in the same snap-fit ​​plate group to separate from each other. The drive block can realize the synchronous separation of the two snap-fit ​​plates in the same snap-fit ​​plate group, thereby releasing the telescopic locking mechanism from fixing the connecting column.

[0042] 6. The first and second limit rods can control the rotation angle of the drive block, thereby controlling the contact state of the major or minor axis of the elliptical drive block with the two locking plates in the same locking plate group. That is, when the first limit rod abuts with one of the second limit rods, the major axis of the elliptical drive block abuts with the two locking plates in the same locking plate group; when the first limit rod abuts with the other second limit rod, the minor axis of the elliptical drive block abuts with the two locking plates in the same locking plate group. This allows the construction personnel to accurately control the state of the drive block, thus facilitating the operation of the unlocking mechanism. Attached Figure Description

[0050] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0051] This application discloses a bamboo-joint stake grab bar. (Refer to...) Figure 1 and Figure 2 The bamboo-joint pile grab rod includes a pile body 1. Multiple connecting posts 2 are evenly distributed along the circumference of the pile body 1 on one side. Multiple connecting holes, each matching a connecting post 2, are opened on one side of the pile body 1, with the connecting posts 2 located within these holes. Multiple locking plate assemblies 3 are arranged on the other side of the pile body 1, each corresponding to a connecting post 2. Multiple locking holes 11 are opened on the side of the pile body 1 furthest from the connecting posts 2, with the locking plate assemblies 3 located within these holes. A telescopic locking mechanism 4 is provided between the connecting post 2 and the locking plate assembly 3 on the adjacent pile body 1. The telescopic locking mechanism 4 is used to extend or retract the connecting post 2 outward from the connecting hole on the pile body 1, and to connect the connecting post 2 with the corresponding locking plate assembly 3.

[0052] Reference Figure 2 and Figure 3The locking plate assembly 3 includes two symmetrically arranged locking plates 31. A sliding groove 12 is also provided on the side of the pile body 1 away from the connecting column 2. The sliding groove 12 communicates with the locking hole 11, and the locking plate 31 slides within the sliding groove 12. An unlocking mechanism 5 is also provided between the multiple locking plate assemblies 3. The unlocking mechanism 5 is used to drive the two locking plates 31 in each locking plate assembly 3 to separate from each other.

[0053] When construction workers need to splice bamboo-joint piles, they first lift the pile body 1 to be spliced, then align the connecting hole on one side of the pile body 1 with the corresponding locking hole 11 on the same side of the pile body 1 in the soil. Then, the telescopic locking mechanism 4 drives multiple connecting columns 2 to be inserted into the locking holes 11, and the telescopic locking mechanism 4 locks the connecting columns 2 with the clamping plate group 3, thereby achieving a quick connection between two adjacent bamboo-joint piles. If the pile body 1 experiences local cracking or other emergencies during the pile driving process, the construction workers can quickly release the locking status of the connecting columns 2 and the clamping plate group 3 through the unlocking mechanism 5, thereby quickly disconnecting the connection between the two bamboo-joint piles.

[0054] Reference Figure 3 and Figure 4 The telescopic locking mechanism 4 includes multiple drive screws 41, each threadedly connected to one side of a multiple connecting post 2 near the pile body 1, with the drive screws 41 located within connecting holes. A support plate 42 is fixedly sleeved on the side of the drive screw 41 away from the connecting post 2. A support groove 13 is also provided inside the pile body 1, communicating with the connecting holes, and the support plate 42 is rotatably connected to the support groove 13. A linkage assembly 43 is provided between the multiple drive screws 41, which drives the multiple drive screws 41 to rotate synchronously. A guide member 44 is provided between the connecting post 2 and the pile body 1, which guides the movement of the connecting post 2 and restricts its rotation. The guide member 44 is a guide strip fixed along one side of the length of the connecting post 2, and a guide groove 14 is provided on the pile body 1, within which the guide strip slides. A snap-fit ​​assembly 45 is provided between the connecting post 2 and the corresponding snap-fit ​​plate group 3 of the adjacent pile body 1, which fixes the connecting post 2 to the snap-fit ​​plate group 3.

[0055] Reference Figure 3 and Figure 4The linkage component 43 includes multiple drive gears 431, each fixedly sleeved on one end of multiple drive screws 41. A drive gear ring 432 is rotatably connected inside the pile body 1, and the drive gear ring 432 meshes with all the drive gears 431. A first bevel gear 433 is fixedly sleeved on the outer wall of the drive gear ring 432. A control rod 434 is rotatably connected inside the pile body 1, and a second bevel gear 435 is fixedly sleeved on one end of the control rod 434. The first bevel gear 433 and the second bevel gear 435 mesh with each other. The side of the control rod 434 away from the second bevel gear 435 passes through the pile body 1 and is located on the outside of the pile body 1. A drive wheel 436 is fixedly sleeved on the outer end of the control rod 434, which is used to facilitate the rotation of the control rod 434 by construction personnel.

[0056] Reference Figure 3 and Figure 5 The snap-fit ​​assembly 45 includes a connecting block 451 fixedly sleeved on the end of the connecting post 2 away from the driving screw 41. The connecting block 451 is frustum-shaped, and its cross-section gradually decreases from top to bottom. Two snap-fit ​​blocks 452 are fixedly mounted on the side of the two snap-fit ​​plates 31 in the same snap-fit ​​plate group 3, respectively, and the side of the two snap-fit ​​blocks 452 in the same snap-fit ​​plate group 3, which are close to each other, is inclined, with the inclination direction from top to bottom. Multiple springs 453 are fixedly mounted on the side of the two snap-fit ​​blocks 452 that are far from each other, and the springs 453 are always in a compressed state. A limiting element is provided between the snap-fit ​​plate 31 and the pile body 1. The limiting element is used to prevent the snap-fit ​​plate 31 from easily disengaging from the sliding groove 12. The limiting element is a limiting block 454 fixed on one side of the snap-fit ​​plate 31. A limiting groove is opened in the pile body 1, and the limiting groove communicates with the sliding groove 12, with the limiting block 454 sliding within the limiting groove.

[0057] When connecting two piles 1 using the telescopic locking mechanism 4, the construction worker first rotates the drive wheel 436, which in turn rotates the control rod 434. The control rod 434 then rotates the second bevel gear 435, which in turn rotates the first bevel gear 433 and the drive gear ring 432. Next, the drive gear ring 432 synchronously rotates multiple drive gears 431, which in turn rotate multiple drive screws 41. Subsequently, under the guidance and limiting action of the guide block and guide groove 14, the drive screws 41 drive multiple connecting posts 2 to extend out of the connecting holes and insert into the locking holes 11. Then... With the cooperation of the inclined surfaces of connecting block 451 and locking block 452, connecting block 451 can drive the two locking blocks 452 and the two locking plates 31 to move away from connecting block 451, so that spring 453 is further compressed. Then, connecting post 2 drives connecting block 451 to move downward. After connecting block 451 is fully inserted into locking hole 11, the construction personnel restore the unlocking mechanism 5 to its initial state. Under the action of spring 453, the two locking plates 31 can move to the side that is closer to each other and abut against the top of connecting block 451, thereby fixing connecting block 451 into locking hole 11, and thus fixing connecting post 2.

[0058] Reference Figure 5 and Figure 6 The unlocking mechanism 5 includes multiple rotating shafts 51 rotatably connected within the pile body 1. Each rotating shaft 51 corresponds one-to-one with a multiple connecting post 2, and the rotating shafts 51 are located within locking holes 11. A driving block 52 is fixedly sleeved on each rotating shaft 51. The driving block 52 has an elliptical cross-section and simultaneously abuts against two snap-fit ​​plates 31 in the same snap-fit ​​plate group 3. A driving assembly 53 is provided between the multiple rotating shafts 51, and the driving assembly 53 is used to control the synchronous rotation of the multiple rotating shafts 51.

[0059] Reference Figure 5 and Figure 6 The drive assembly 53 includes multiple transmission gears 531 that are respectively fixedly sleeved on multiple rotating shafts 51. A transmission gear ring 532 is rotatably connected inside the pile body 1, and the transmission gear ring 532 meshes with the multiple transmission gears 531. A third bevel gear 533 is fixedly sleeved on the outer wall of the transmission gear ring 532. A drive rod 534 is rotatably connected inside the pile body 1. A fourth bevel gear 535 and a knob 536 are fixedly sleeved at one end of the drive rod 534. The third bevel gear 533 and the fourth bevel gear 535 mesh with each other. The side of the drive rod 534 away from the fourth bevel gear 535 passes through the pile body 1 and is located on the outside of the pile body 1. A storage groove 15 is opened on the outside of the pile body 1. The storage groove 15 is a sink. The knob 536, the first limiting rod 537, and the second limiting rod 538 are all located in the storage groove 15. A first limiting rod 537 is fixedly provided on one side of the knob 536, and two second limiting rods 538 are fixedly provided in the storage slot 15. The first limiting rod 537 is located between the two second limiting rods 538.

[0060] After the connecting column 2 is fixed by the telescopic locking mechanism 4, the short axis of the ellipse abuts against the side of the two locking plates 31 in the same locking plate group 3. When the unlocking mechanism 5 causes the two locking plates 31 in the multiple locking plate groups 3 to separate from each other, the construction personnel first turn the knob 536. The knob 536 drives the drive rod 534 to rotate. The drive rod 534 drives the third bevel gear 533 and the fourth bevel gear 535 to rotate. Then the third bevel gear 533 drives the transmission gear ring 532 to rotate. The transmission gear ring 532 synchronously drives multiple transmission gears 531 to rotate. The multiple transmission gears 531 can drive multiple rotating shafts 51 to rotate synchronously. Then the rotating shafts 51 drive the drive block 52 to rotate. When the long axis of the ellipse abuts against the side of the two locking plates 31 in the same locking plate group 3, the long axis of the ellipse of the drive block 52 can drive the two locking plates 31 in the same locking plate group 3 to separate from each other, thereby releasing the telescopic locking mechanism 4 from fixing the connecting column 2. Meanwhile, the first limiting rod 537 and the second limiting rod 538 can control the rotation angle of the drive block 52, thereby controlling the contact state of the major axis or minor axis of the elliptical drive block 52 with the two snap-fit ​​plates 31 in the same snap-fit ​​plate group 3. That is, when the first limiting rod 537 abuts with one of the second limiting rods 538, the major axis of the elliptical drive block 52 abuts with the two snap-fit ​​plates 31 in the same snap-fit ​​plate group 3. When the first limiting rod 537 abuts with the other second limiting rod 538, the minor axis of the elliptical drive block 52 abuts with the two snap-fit ​​plates 31 in the same snap-fit ​​plate group 3. This allows the construction personnel to accurately control the state of the drive block 52.

[0061] This application also provides a construction method for a bamboo-joint pile grab rod, applicable to one of the bamboo-joint pile grab rods mentioned above, and the construction steps are as follows:

[0062] S. Clear the foundation, mark and mark the lines, and measure and locate the position;

[0063] S. Weld the pile tip to the bottom of the first bamboo-joint pile;

[0064] S. Connect the bamboo-joint piles to the pile driver and drive the bamboo-joint piles into the foundation using the pile driver;

[0065] S. Lift the next section of bamboo pile using a pile driver and align the multiple locking holes 11 with the multiple corresponding connecting holes;

[0066] S. By rotating the drive wheel 436, the drive wheel 436 can control the telescopic locking mechanism 4 to drive multiple connecting posts 2 to extend out of the connecting hole and insert into the locking hole 11. The snap-fit ​​plate 31 in the snap-fit ​​plate group 3 can fix the connecting block 451 at one end of the connecting post 2, thereby completing the locking of the connecting post 2 and the snap-fit ​​plate group 3 and realizing the connection of the pile.

[0067] S. Repeat step SS until the overall driving depth of the bamboo-joint piles meets the construction requirements.

[0068] The implementation principle of the bamboo-joint pile grab rod and construction method in this application embodiment is as follows: When construction personnel need to splice bamboo-joint piles, they first lift the pile body 1 to be spliced ​​using a pile driver. Then, they align the multiple connecting holes on the pile body 1 with the multiple corresponding locking holes 11 on the pile body 1. Subsequently, the construction personnel rotate the drive wheel 436, which controls the telescopic locking mechanism 4 to drive multiple connecting columns 2 to extend from the connecting holes and insert them into the locking holes 11. Then, the connecting block 451 at one end of the connecting column 2 is locked by the clamping plate group 3, thus realizing the rapid connection between two adjacent bamboo-joint piles. If the pile body 1 experiences partial [unclear] during the pile driving process, In case of emergencies such as cracking, construction workers can quickly release the locking state of the telescopic locking mechanism 4 by turning the knob 536, thereby quickly disconnecting the connection between the two bamboo-joint piles. When splicing bamboo-joint piles, the telescopic locking mechanism 4 can achieve a quick connection between two adjacent bamboo-joint piles. The operation process is simple and convenient, does not require construction workers to have strong welding skills, is less affected by human factors, improves the construction error tolerance rate, and the connection is firm and reliable. This makes it less likely for the connection between two adjacent bamboo-joint piles to break when the pile top is under tension. Moreover, if local cracking occurs at the connection of the pile body 1 during the pile driving process, the connection between adjacent pile bodies 1 can be quickly disconnected.

[0069] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
