Description

Technical Field

[0001] This utility model relates to the field of building pile technology, specifically a building pile for engineering construction. Background Technology

[0002] Construction piles are columnar load-bearing components deeply embedded in the ground. They transfer building loads (vertical forces, horizontal forces, etc.) to deep, stable soil or rock layers, solving problems such as weak soil, insufficient bearing capacity, or excessive settlement in shallow foundations. Their core function is to enhance foundation stability and reduce settlement. They are widely used in high-rise buildings, bridges, ports, and other projects. They are mainly divided into two categories: precast piles (manufactured in a factory and then driven in) and cast-in-place piles (drilled and poured on-site). They are a key technical support for foundation engineering.

[0003] A search revealed that Chinese patent CN221663643U discloses a building pile for construction engineering, including a limiting pile. The outer wall of the limiting pile has several connecting holes, and limiting springs are fixed inside the connecting holes respectively. One end of the limiting spring is fixed with a compression block, and the end of the compression block facing the limiting spring is fixed with a horizontal pile. The limiting spring is sleeved on the outer wall of the horizontal pile. A fixed top column is fixed on the top surface of the limiting pile, and a fixed bottom column is fixed on the bottom surface of the limiting pile. A pile body penetrates through the interior of the limiting pile.

[0004] During use, the pile tip and pile body are fixed as a single unit. This makes it impossible to quickly adapt to specific pile tips (such as conical rock-breaking tips or enlarged-base friction tips) according to actual geological conditions (such as hard rock, gravel, and soft soil). This results in low penetration efficiency, easy deviation and jamming, and the wear resistance of key parts cannot be improved by replacing them with high-performance materials (alloy steel or composite materials). At the same time, when the pile tip is worn or damaged, the entire pile must be discarded, resulting in high construction costs and poor flexibility. This seriously restricts the quality and economy of engineering projects in complex strata. However, if the pile tip and pile body are simply made detachable, they do not have good stability during use and lack the purpose of connection and reinforcement. Utility Model Content

[0005] The purpose of this utility model is to provide a construction pile for engineering construction to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a construction pile for engineering construction, comprising a steel pipe pile, wherein a connecting mechanism is provided at the bottom of the steel pipe pile, a pile tip is provided at the bottom of the connecting mechanism, and a locking mechanism is provided inside the pile tip;

[0007] The locking mechanism includes a base plate, which is fixedly connected to the inner wall of the locking mechanism. A fixed arm is fixedly connected to the top of the base plate, and a support box is fixedly connected to the inner side of the fixed arm. A spring is fixedly connected to the inner wall of the support box, and a rectangular plate is fixedly connected to the top of the spring. A support column is fixedly connected to the top of the rectangular plate, and a top plate is fixedly connected to the top of the support column. A locking shaft is fixedly connected to the inside of the top plate, and a connecting plate is fixedly connected to the outer side of the rectangular plate. A push block is fixedly connected to the side of the connecting plate away from the rectangular plate, and a baffle is fixedly connected to the bottom of the connecting plate.

[0008] Preferably, the rectangular plate is slidably connected to the inner wall of the support box, the top of the support box has an opening, and the support column passes through the opening, so that the support column can move through the opening.

[0009] Preferably, the support box has a movable opening on its outer side, and the connecting plate passes through the movable opening, so that the connecting plate can be moved through the movable opening.

[0010] Preferably, a rectangular opening is provided on the outer side of the pile tip, and the connecting plate is movably connected to the inner wall of the rectangular opening, so that the connecting plate can move up and down through the rectangular opening.

[0011] Preferably, a through hole is provided at the top of the pile tip, and the locking shaft passes through the through hole, allowing the locking shaft to move through the through hole.

[0012] Preferably, the connecting mechanism includes a sealing ring, which is fixedly connected to the bottom end of the steel pipe pile. A high-strength alloy internal threaded sleeve is fixedly connected to the inner ring of the sealing ring, and a sealing sleeve and a high-strength alloy external threaded head are fixedly connected to the top of the pile tip, which facilitates a stable connection and positioning between the pile tip and the steel pipe pile.

[0013] Preferably, the high-strength alloy internal thread sleeve is threaded to the outer wall of the high-strength alloy external thread head, and a retaining hole is provided at the bottom of the high-strength alloy external thread head. The locking shaft is movably connected to the inner wall of the retaining hole, so that the mutual cooperation between the locking shaft and the retaining hole limits the sealing ring.

[0014] Compared with the prior art, this utility model provides a construction pile for engineering construction, which has the following beneficial effects:

[0015] 1. The building piles used in this project, through the setting of a locking mechanism combined with a spring-driven automatic locking mechanism, form a rigid anti-rotation constraint after the threads are tightened. This design effectively resists the risk of thread loosening caused by construction vibration. At the same time, the sealing ring and sealing sleeve work together to isolate water and soil erosion, significantly improving the reliability and durability of pile foundation connection under complex geological conditions.

[0016] 2. The construction piles used in this project employ a detachable pile tip structure through a connecting mechanism, allowing for rapid replacement of specialized pile tips (such as conical rock-breaking tips and expanded-base friction tips) based on soil and rock conditions (such as hard rock layers and quicksand layers). Key stress-bearing parts are locally reinforced with high-strength alloy materials, and the locking mechanism features one-button unlocking and automatic reset functions, enabling rapid disassembly and reuse of pile tips. This solves the problems of low penetration efficiency and misalignment jamming associated with integrated pile tips, significantly reduces the cost of scrapping the entire pile due to localized wear, and improves the adaptability and resource utilization rate in complex geological formations.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] This utility model provides the following technical solution:

[0028] Example 1

[0029] Combination Figures 1 to 6 A type of construction pile for engineering construction includes a steel pipe pile 1, a connecting mechanism 3 at the bottom of the steel pipe pile 1, a pile tip 4 at the bottom of the connecting mechanism 3, and a locking mechanism 2 inside the pile tip 4.

[0030] The locking mechanism 2 includes a base plate 21, which is fixedly connected to the inner wall of the locking mechanism 2. A fixed arm 22 is fixedly connected to the top of the base plate 21. A support box 23 is fixedly connected to the inner side of the fixed arm 22. A spring 24 is fixedly connected to the inner wall of the support box 23. A rectangular plate 25 is fixedly connected to the top of the spring 24. A support column 28 is fixedly connected to the top of the rectangular plate 25. A top plate 29 is fixedly connected to the top of the support column 28. A locking shaft 201 is fixedly connected inside the top plate 29. A connecting plate 26 is fixedly connected to the outer side of the rectangular plate 25. A push block 27 is fixedly connected to the side of the connecting plate 26 away from the rectangular plate 25. A baffle 202 is fixedly connected to the bottom of the connecting plate 26.

[0031] The rectangular plate 25 is slidably connected to the inner wall of the support box 23. The top of the support box 23 has an opening, through which the support column 28 passes. The precise sliding fit and the opening guide design inside the support box 23 ensure that the locking shaft 201 can be lifted vertically without deviation and avoid jamming. The spring force transmission path is stable, ensuring that the locking force is accurately applied to the locking hole.

[0032] The support box 23 has a movable opening on its outer side, through which the connecting plate 26 passes. The movable opening provides rigid guidance for the connecting plate 26, efficiently converting the external force of the push block 27 into the linear motion of the rectangular plate 25, thereby reducing energy loss.

[0033] A rectangular opening is provided on the outer side of the pile tip 4, and the connecting plate 26 is movably connected to the inner wall of the rectangular opening. The rectangular opening and the connecting plate 26 are dynamically matched, so that the operation interface is exposed on the side wall of the pile tip 4. Construction personnel can directly touch the push block 27 and achieve quick unlocking without disassembling the parts.

[0034] The top of the pile tip 4 has a through hole, through which the locking shaft 201 passes. The through hole precisely positions the movement trajectory of the locking shaft 201, ensuring that it is accurately aligned with the bottom locking hole of the high-strength alloy external thread head 33, thus eliminating the risk of locking failure caused by misalignment.

[0035] Example 2

[0036] See Figures 1 to 6 Furthermore, based on Embodiment 1, the connecting mechanism 3 further includes a sealing ring 31, which is fixedly connected to the bottom end of the steel pipe pile 1. A high-strength alloy internal threaded sleeve 32 is fixedly connected to the inner ring of the sealing ring 31. A sealing sleeve 34 and a high-strength alloy external threaded head 33 are fixedly connected to the top of the pile tip 4, respectively. The high-strength alloy internal threaded sleeve 32 and the high-strength alloy external threaded head 33 provide the main load-bearing mechanical connection. The sealing ring 31 and the sealing sleeve 34 form a double-stage radial sealing barrier, which simultaneously solves the problems of structural strength and water and soil sealing, and adapts to the deep foundation seepage pressure environment.

[0037] Among them, the high-strength alloy internal thread sleeve 32 is threaded to the outer wall of the high-strength alloy external thread head 33. The high-strength alloy external thread head 33 has a locking hole at the bottom. The locking shaft 201 is movably connected to the inner wall of the locking hole. After the locking shaft 201 is inserted into the locking hole, it forms a rigid anti-rotation constraint, which completely prevents the threaded pair from loosening under vibration conditions.

[0038] In actual operation, when this device is used, the high-strength alloy internal thread sleeve 32 and the high-strength alloy external thread head 33 cooperate with each other to achieve the purpose of connecting and installing the pile tip 4 and the steel pipe pile 1. The sealing sleeve 34 and the sealing ring 31 can ensure the sealing of the connection and reduce the impact of the outside on the connection.

[0039] Pressing down pushes the push block 27 to move it. The push block 27 can drive the rectangular plate 25 to move downward through the connecting plate 26. The rectangular plate 25 can compress the spring 24, and the rectangular plate 25 can drive the top plate 29 to move through the support column 28. The top plate 29 can drive the locking shaft 201 to move downward. At the same time, the high-strength alloy internal thread sleeve 32 can be screwed into the outer wall of the high-strength alloy external thread head 33. When the high-strength alloy internal thread sleeve 32 is fully screwed into the outer wall of the high-strength alloy external thread head 33, the push block 27 can be stopped. The spring 24, which is in a compressed state, will push the rectangular plate 25 to rise. The rectangular plate 25 can drive the top plate 29 to rise through the support column 28, so that the top plate 29 drives the locking shaft 201 to insert into the inner wall of the clasp hole opened at the bottom of the sealing ring 31. This prevents the steel pipe pile 1 and the pile tip 4 from rotating relative to each other, thereby achieving the purpose of locking and reinforcement and reducing the risk of loosening of the connection between the high-strength alloy internal thread sleeve 32 and the high-strength alloy external thread head 33.
