Description

Technical Field

[0001] The invention relates to the technical field of pipe pile splicing design, and in particular to a pipe pile splicing structure and a pipe pile disassembly method thereof. Background Art

[0002] In the field of foundation construction, pipe piles are an important basic structural component. They are usually designed as a whole, that is, the length of the pipe piles is fixed during production and cannot be adjusted according to actual construction needs. Although this design has certain advantages in structural stability, it has many inconveniences in the actual construction process.

[0003] First, the length of traditional pipe piles is fixed and cannot be flexibly adjusted according to the specific needs of the construction site. When the conditions of the construction site change, it may be necessary to replace pipe piles of different lengths, which not only increases the construction cost, but also prolongs the construction period;

[0004] Secondly, the main technical personnel in multiple construction projects of the applicant discovered that in urban renewal or old building demolition projects, some places need to preset some pipe piles for foundation construction. After the construction of some foundations is completed, some of the original preset pipe piles need to be removed. However, according to the existing pipe pile structure, the fixed length cannot be removed, and it is extremely difficult to dismantle it. The dismantling requires complicated crushing, and some even damage the surrounding environment facilities, which also leads to a decrease in the reuse rate of the pipe piles and increases the construction cost.

[0005] Therefore, the inventor of the applicant, after various innovative improvements, proposed a splicing structure for detachable pipe piles and a method for disassembling the pipe piles to solve the problem. Summary of the invention

[0006] In order to solve the above technical problems, a pipe pile splicing structure is provided, including a splicing assembly arranged at the connection between two pipe bodies, characterized in that the splicing assembly includes a ring plate 1, a circle of two-way internally threaded pipe is inserted and rotatably installed on the ring plate 1, the internal thread of the two-way internally threaded pipe is connected to two screws with opposite thread directions, a positioning rod is fixed to the outer end of the screw, the outer wall of the ring plate 1 is fitted with a ring plate 2 for rotation, the ring plate 2 and the two-way internally threaded pipe are connected with a driving assembly for driving the ring plate 2 and the two-way internally threaded pipe to rotate synchronously, an opening is provided on the end face of the connection between the two pipe bodies, and the connection or disconnection is carried out by extending and contracting the positioning rod through the synchronous rotation of the two-way internally threaded pipe to the opening of the two pipe bodies.

[0007] The driving assembly includes a tooth block arranged on the inner wall of the second driving ring plate, and a gear is arranged on the periphery of the internal threaded tube. The tooth block meshes with the gear, and the gear is fixed outside the bidirectional internal threaded tube and located below the first ring plate.

[0008] The connecting ends of the tube body are each provided with a connecting plate and a butt tube. One end of the tube body fits the connecting plate, which is fixed to the outer wall of the butt tube and penetrates into the tube body. The end faces of the tube body and the connecting plate are respectively provided with corresponding openings and rod holes. The positioning rod is extended and retracted to the tube body, the openings and rod holes of the connecting plate, and the ring plate is sleeved on the outer wall of the butt tube.

[0009] The splicing assembly also includes a ring plate three sleeved on the outer wall of the butt-jointed tube, the ring plate three fits with the bottom of the ring plate two and is located below the gear, the bidirectional internally threaded tube passes through the circular hole of the ring plate three, the two are close but not in contact, and a sealing gasket is arranged on the inner wall of the circular hole to contact the outer wall of the bidirectional internally threaded tube.

[0010] An annular sliding block is fixed on the inner wall of the second driving ring plate and slides in the opening of the outer wall of the first ring plate.

[0011] A connecting piece is fixed on the top of the two end surfaces of the ring plate, and the connecting piece is also fitted with the top of the ring plate. After the connecting piece is rotated at a certain angle, its own screw holes are aligned with the screw holes on the surface of the ring plate.

[0012] The diameter of the positioning rod is larger than that of the screw rod, a row of convex strips is arranged on the outer wall of the positioning rod, and the connecting plate rod hole and the inner wall of the opening of the tube body are both provided with grooves corresponding to the convex strips.

[0013] The connection plate is fixed between the butt-jointed pipes and has a row of triangular blocks fixedly connected thereto.

[0014] A pipe pile disassembly method based on the pipe pile splicing structure as described above is characterized by comprising the following steps:

[0015] The connection between the two pipe bodies adopts a splicing structure. When disassembly is required, the ring plate 2 of the driving assembly connected to the splicing assembly is rotated forward by applying force to retract the positioning rod to disconnect the connection between the two pipe piles.

[0016] If the connection is further fixed by screw ring plate 1 of the connecting piece, first remove the screw of the connecting piece, and then apply force to reversely rotate the ring plate 2 of the driving assembly connected to the splicing assembly.

[0017] Compared with the related art, the structure and disassembly of the present invention have the following beneficial effects:

[0018] The pipe pile splicing structure provided by the present invention is used for connecting pipe piles to each other, realizing a pipe pile that can be disassembled and connected at any time. By adopting the design of splicing components and driving components, the pipe pile structure can be disassembled more conveniently when it needs to be disassembled, and can be connected and disassembled for use according to the length requirements of the pipe piles. Compared with traditional pipe piles with an integral design, it is more flexible and practical.

[0019] When the pipe piles connected based on the pipe pile splicing structure need to be disassembled, it is only necessary to apply force to reversely rotate the ring plate 2 of the driving assembly connected to the splicing assembly to retract the positioning rod to disconnect the connection between the two pipe piles, thereby greatly simplifying the disassembly process, reducing construction costs and increasing the flexibility of construction use.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] As shown in the figure, Figure 1-Figure 6The present invention discloses a pipe pile splicing structure, which is also a detachable pipe pile structure, including a pipe body 1. The pipe body 1 is a pipe body 1 connected in two sections. The connecting ends of the pipe body 1 are provided with a connecting plate 2 and a butt tube 21. One end of the pipe body 1 fits the connecting plate 2, and the connecting plate 2 is fixed on the outer wall of the butt tube 21, and the butt tube 21 penetrates the pipe body 1. The end faces of the pipe body 1 and the connecting plate 2 are respectively provided with corresponding openings and rod holes. The outer wall of the butt tube 21 is also provided with a splicing component 3 of a retractable positioning rod 34, which is connected or disconnected by extending or retracting the positioning rod 34 to the openings and rod holes of the two pipe bodies 1 and the connecting plate 2.

[0029] The splicing assembly 3 includes a ring plate 1 31 fixed on the outer wall of the butt-jointed tube 21, a circle of bidirectional internally threaded tube 32 is inserted and rotatably installed on the ring plate 1 31, and two screws 33 with opposite thread directions are connected to the internal threads of the bidirectional internally threaded tube 32, and a positioning rod 34 is fixed to the outer end of the screw 33, and the positioning rod 34 passes through the rod hole of the connecting plate 2 and can be inserted into the opening of the tube body 1, and the outer wall of the ring plate 1 31 is fitted with a ring plate 2 35 for rotationally installing, and the ring plate 2 35 and the bidirectional internally threaded tube 32 are connected with a driving assembly 4 for driving the ring plate 2 35 and the bidirectional internally threaded tube 32 to rotate synchronously, and an annular slider 38 is fixed to the inner wall of the driving ring plate 2 35, which slides in the opening of the outer wall of the ring plate 1 31;

[0030] The driving assembly 4 includes a gear block 42 arranged on the inner wall of the second driving ring plate 35 , the gear block 42 is meshed with a gear 41 , and the gear 41 is fixed to the outside of the bidirectional internal threaded tube 32 and is located below the first ring plate 31 .

[0031] As described above, through the design of the splicing component 3 and the driving component 4, when installing and docking, the original integral pipe body 1 is divided into several sections, which can be two ends, three ends, or more. When splicing, one end of the pipe body 1 is initially fixed to the docking pipe 21 through the connecting plate 2, and the docking pipe 21 is then inserted into the other section of the pipe body 1 to be spliced, and then the driving component 4 is operated, that is, the ring plate 2 35 is rotated. Due to the meshing action of the tooth block 42 and the gear 41, the two-way internal threaded pipe 32 is driven to rotate synchronously, and the two screws 33 with opposite thread directions connected to the internal thread of the two-way internal threaded pipe 32 will move in opposite directions, thereby driving the positioning rod 34 to move, so that the positioning rod 34 passes through the rod hole of the connecting plate 2 and is inserted into the opening of the pipe body 1, so as to achieve a stable docking between the pipe body 1 and the connecting plate 2. Due to the design of the two-way internal threaded pipe 32, the two positioning rods 34 can be driven to move in opposite or opposite directions at the same time, thereby improving the docking efficiency and stability.

[0032] A ring plate three 36 is fixed to the outer wall of the butt-jointed pipe 21, and the ring plate three 36 is fitted with the bottom of the ring plate two 35 and is located below the gear 41. The two-way internally threaded pipe 32 passes through the circular hole of the ring plate three 36, and the two are close but not in contact. A sealing gasket is arranged on the inner wall of the circular hole to contact the outer wall of the two-way internally threaded pipe 32. A connecting piece 37 is fixed to the top of the ring plate two 35, and the connecting piece 37 is also fitted with the top of the ring plate one 31. After the connecting piece 37 is rotated at a certain angle (at this time, the overall splicing is just completed), its own screw holes are aligned with the screw holes on the surface of the ring plate one 31.

[0033] Furthermore, the design of the connecting piece 37 not only fits with the top of the ring plate 1 31, but also after it rotates a certain angle and completes the assembly, it can be fixed with screws through its own screw holes and the screw holes on the surface of the ring plate 1 31, thereby strengthening the connection between the ring plate 2 35 and the ring plate 1 31, avoiding unnecessary rotation of the ring plate 2 35 when used for a long time or under the action of external forces, ensuring the stability and reliability of the splicing assembly 3 and the drive assembly 4, and the setting of the ring plate 3 36 effectively prevents external impurities or moisture from entering the space between the gear 41 and the gear block 42, protecting the precision parts of the drive assembly 4 and extending the service life of the overall device. When disassembling, it is possible to first remove the screws of the connecting piece and then reversely rotate the ring plate 2, thereby greatly simplifying the disassembly process, reducing construction costs and construction flexibility.

[0034] The diameter of the positioning rod 34 is larger than that of the screw rod 33 . The outer wall of the positioning rod 34 is provided with a row of convex strips, and the rod hole of the connecting plate 2 and the inner wall of the opening of the tube body 1 are both provided with grooves corresponding to the convex strips.

[0035] Furthermore, with such a design, the screw rod 33 and the positioning rod 34 cannot rotate, so that when the bidirectional internally threaded tube 32 rotates, the positioning rod 34 can move up and down smoothly.

[0036] The connecting plate 2 is fixed between the butt-jointed pipes 21 and has a row of triangular blocks 22 fixedly connected thereto, and is of solid design.

[0037] Furthermore, the triangular block 22 strengthens the strength between the connecting plate 2 and the butt pipe 21 , thereby improving the connection strength between the connecting plate 2 and the butt pipe 21 as an intermediate piece.

[0038] A pipe pile disassembly method based on the pipe pile splicing structure as described above comprises the following steps:

[0039] The connection between the two pipe bodies 1 adopts a splicing structure. When disassembly is required, the ring plate 2 of the driving assembly connected to the splicing assembly can be retracted into the positioning rod to disconnect the connection between the two pipe piles by applying force to rotate forward.

[0040] If the connection adopts the further fixing of the screw ring plate 1 31 of the connecting piece, first remove the screw of the connecting piece, and then apply force to reversely rotate the ring plate 2 of the driving assembly connected to the splicing assembly. It is very easy to realize disassembly.

[0041] The above structure can also be fully realized: by adopting the design of splicing components and driving components, the pipe pile structure can be more convenient to disassemble when it needs to be disassembled, and can be connected and disassembled according to the length requirements of the pipe piles. Compared with the traditional integral design of pipe piles, it is more flexible and practical. It only needs to apply force to rotate the ring plate 2 of the driving component connected to the splicing component in the forward and reverse directions to extend or retract the positioning rod to connect or disconnect the two pipe piles, thereby greatly simplifying the disassembly process and reducing construction costs and construction flexibility.
