Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of hollow-square integrated pile tip, especially hollow-square integrated pile tip structure. BACKGROUND

[0002] The hollow-square integrated pile tip refers to a specially designed pile tip, which is commonly used in pile foundation engineering, especially under complex geological conditions. The design of the pile tip combines the advantages of hollow and solid pile tips to improve the piling efficiency and adaptability.

[0003] At present, the hollow-square integrated pile tip is mainly composed of a pile tip and a hollow plate. The large end of the pile tip is welded to one end of the hollow plate, and the other end of the hollow plate is fixedly connected with a pile driver. During piling operation, the pile tip can provide better support and stability to prevent slipping or deviation, and the hollow plate can reduce the resistance of the soil during piling to improve the efficiency. However, when the hollow-square integrated pile tip is used in some difficult-to-penetrate strata such as dense sand layer or rock stratum, the hollow plate is constantly colliding with some relatively hard substances such as sand or rock, which causes the hollow plate to deform or be damaged after a long time of collision, thereby affecting the piling work.

[0004] In order to not affect the piling work, the hollow-square integrated pile tip after deformation or damage needs to be replaced. Since the hollow plate and the pile tip are designed as a whole, the pile tip cannot be separated from the damaged hollow plate when replacing the hollow-square integrated pile tip. Therefore, the hollow plate can only be scrapped together with the pile tip, which cannot be reused, thereby increasing the cost of pile foundation construction. UTILITY MODEL CONTENTS

[0034] When hollow -core slab 2 and solid slab 1 are connected through screw rod 4 and limiting screw nut 10, the one end of solid slab 1 is connected with the piling end of piling equipment away from hollow -core slab 2, can carry out piling operation through pile tip 3.

[0035] If hollow -core slab 2 outer wall and hard object collide and appear damage or deformation and affect pile foundation construction during piling, through the big end of screw rod 4 is rotated through dismounting tool, until the big end of screw rod 4 falls from the inner chamber of limiting screw nut 10, can separate hollow -core slab 2 and solid slab 1, then separate pile tip 3 and hollow -core slab 2, can replace damaged or deformed hollow -core slab 2, and the hollow -core slab 2 and solid slab 1 and pile tip 3 after replacement are reassembled, so as to realize the reuse of pile tip 3 and solid slab 1, reduce the cost when pile foundation construction.

[0038] The accommodating groove 9 is provided with an accommodating hole matched with the threaded rod 4 on the side away from the insertion hole. With continuous rotation of the threaded rod 4 in the inner cavity of the limiting nut 10, the small end of the threaded rod 4 finally enters the inner cavity of the accommodating hole, until the small end of the threaded rod 4 is attached to the inner wall of the opening end of the accommodating hole, and the large end of the threaded rod 4 is tightly attached to one end of the hollow plate 2, thereby increasing the distance between the small end of the threaded rod 4 and the limiting nut 10, preventing the threaded rod 4 from being separated from the limiting nut 10 due to vibration during pile driving, and affecting the pile driving operation.

[0039] The shape of the inner wall of the opening end of the accommodating groove 9 is the same as that of the limiting nut 10. When the limiting nut 10 is installed in the inner cavity of the accommodating groove 9, the outer wall of the limiting nut 10 is attached to the inner wall of the accommodating groove 9. When the small end of the threaded rod 4 is inserted into the inner cavity of the limiting nut 10 and continuously rotated, the limiting nut 10 is prevented from rotating with the threaded rod 4, which is conducive to the assembly of the threaded rod 4 and the limiting nut 10.

[0041] During pile driving, the outer wall of the pile tip 3 first collides with a hard object. After a long time of collision with the hard object, the outer wall of the pile tip 3 is prone to deformation, which affects the subsequent construction of the pile foundation.

[0042] In order to solve the above problems, the large end of the pile tip 3 is fixedly installed with a positioning ring 8, and a plurality of mounting holes are arranged in the annular structure of one end of the hollow plate 2 and one end of the positioning ring 8, and a fastening bolt is detachably installed in the inner cavity of the mounting hole, and the outer part of the fastening bolt is threadedly connected with a fastening nut for limiting the positioning ring 8, wherein the opening shape of one end of the hollow plate 2 is arranged as an annular structure, and the other end is arranged as a quadrilateral structure, the diameter of the positioning ring 8 is greater than the annular structure slot of one end of the hollow plate 2, and less than the shortest side length of the quadrilateral structure slot of the other end, when the pile tip 3 needs to be connected with the hollow plate 2, the tip of the pile tip 3 is inserted from the quadrilateral structure slot to the annular structure slot, until the one end of the positioning ring 8 and the inner wall of the hollow plate 2 are attached, and the middle part of the plurality of mounting hole openings on the outer wall of the positioning ring 8 and the middle part of the plurality of mounting hole openings on the inner wall of the hollow plate 2 are on the same horizontal line, then the small end of the fastening bolt is inserted into the mounting hole on the outer part of the hollow plate 2, and then the fastening nut is sleeved on the small end of the fastening bolt, so that the connection between the hollow plate 2 and the pile tip 3 can be realized through the cooperation of the fastening bolt and the fastening nut.

[0043] When the pile tip 3 needs to be replaced, first, the hollow plate 2 is separated from the solid plate 1, then the fastening nut and the fastening bolt are separated by dismounting tools, and then the pile tip 3 can be taken out from the inside of the hollow plate 2, so that the separation of the hollow plate 2 and the pile tip 3 is realized, so as to replace the damaged pile tip 3.

[0044] During the piling process, the downward movement of the pile tip 3 will compress the mud and air at the bottom of the pile foundation, and the compressed air and mud will hinder the downward movement of the pile tip 3, making it difficult to carry out piling work.

[0045] In order to solve the above problems, the one end of the solid plate 1 and the one end of the hollow plate 2 are provided with positioning holes which are in communication with the other end, and the inner cavity of the positioning hole is detachably installed with an exhaust pipe 5 for exhaust, during the piling process, the air and mud at the bottom of the pile foundation are transferred to the upper part of the solid plate 1 through the exhaust pipe 5, thereby reducing the air resistance and water resistance during the piling process, and improving the piling efficiency and smoothness.

[0046] Among them, the one end of the solid plate 1 and the one end of the hollow plate 2 are provided with a plurality of positioning holes, and a plurality of exhaust pipes 5 can be installed through the plurality of positioning holes, part of the exhaust pipes 5 are used for exhaust and drainage, and the inner cavities of the remaining exhaust pipes 5 are installed with sensors, which can monitor the state of the pile foundation in real time, provide data support, and ensure the construction quality and safety.
