Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a type of anti-sinking stiff composite pile for building engineering. Background Technology

[0002] Building construction, a part of construction engineering, refers to the physical structure formed through the construction of various buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. It includes factories, theaters, hotels, shops, schools, hospitals, and residences, meeting people's needs for production, living, learning, and public activities. In building construction, a foundation is needed to support the building, and the foundation is often composed of building piles.

[0003] A reinforced composite pile is a composite carrier, usually a combination of concrete piles and prestressed pipe piles, and is often used for soft foundations such as silt, cohesive soil, silt, sand, and artificial fill.

[0004] For example, patent document CN217128208U discloses a rigid composite pile, belonging to the technical field of composite pile manufacturing. It includes an inner pile, an outer pile, and a fixed anchor. The outer pile has a sliding groove, and the inner pile is slidably connected to the inner wall of the sliding groove. The outer pile also has an adjustment groove, and the fixed anchor is slidably connected to the inner wall of the adjustment groove. A driving component for moving the fixed anchor is installed inside the outer pile. In this application, when the pressure on the pile foundation increases, the driving component causes the fixed anchor to enter the foundation, thereby enhancing the connection strength between the pile foundation and the foundation. Simultaneously, it can disperse the pressure on the pile foundation into the foundation through the fixed anchor, achieving the purpose of improving the bearing capacity of the pile foundation.

[0005] However, the aforementioned patent documents still have the following shortcomings in practical application:

[0006] The recycling effect is poor because, according to the aforementioned patent documents, the fixing anchor is not retracted after installation, making it difficult to remove the entire composite pile. Furthermore, it is impossible to clean the dirt and other impurities adhering to the surface of the fixing anchor. These impurities can easily cause corrosion and affect the service life of the fixing anchor, resulting in poor recycling effect. Summary of the Invention

A second lifting block is fixedly connected to the end of the second guide post that is far from each other. A longitudinal nail is fixedly connected to the lower end face of the second lifting block. The longitudinal nail is slidably connected to the anti-sinking ring.

[0015] Preferably, it also includes a central column and a shock-absorbing mechanism for cushioning the central column.

[0016] Preferably, the shock absorption mechanism includes a slider, which is symmetrically distributed on the upper sides of the left and right ends of the composite pile body and slidably connected thereto. A first spring is fixedly connected to the upper end of the slider, and the upper end of the first spring is fixedly connected to the composite pile body. A second connecting rod is rotatably connected to the middle of the slider through a pin, and a central column is rotatably connected to the lower end of the second connecting rod through a pin.

[0017] Preferably, a support platform is fixedly connected to the upper end face of the central column, and spring dampers are fixedly connected to both the left and right ends of the upper side of the inner cavity wall of the composite pile body, with a second arc-shaped plate fixedly connected to the piston end of the spring damper.

[0018] Preferably, the upper end of the support platform is also provided with an adjustment mechanism for easy installation.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, after the composite pile body is drilled into the soil, the dual-axis motor is started. Under the action of the lower output end of the dual-axis motor, the first threaded rod rotates, which lowers the first lifting block. When the first lifting block descends, the movement of the first connecting rod drives the transverse nails on both sides to slide in opposite directions simultaneously, so that the transverse nails are inserted into the soil for transverse fixation. Then, under the action of the upper output end of the dual-axis motor, the first rotating shaft rotates, which rotates the first bevel gear, which in turn rotates the second bevel gears on the left and right sides, which in turn rotates the second sliding rods on the left and right sides, driving the second guide column and the second lifting block to move downward, so that the longitudinal nail is inserted into the soil, completing the secondary tightening, which can prevent the composite pile body from settling. At the same time, when it is necessary to dismantle the composite pile body, simply reverse the dual-axis motor to raise the first lifting block, which will cause the transverse and longitudinal nails to retract, canceling the tightening, and making it easy to dismantle the composite pile body. When the transverse nail retracts, the first lifting block moves the rack, causing the gear ring to rotate. The gear ring then rotates the second arc-shaped plate. Simultaneously, under the action of the second spring, the second arc-shaped plate uses a brush to remove dirt and impurities adhering to the surface of the transverse nail. The brush remains in close contact with the transverse nail surface under the action of the second spring, ensuring thorough cleaning of all parts of the transverse nail. This prevents corrosion caused by dirt and impurities, thus ensuring its continued usability. This provides an anti-settlement effect for the entire composite pile, preventing it from sinking into the soil. It offers good stability and allows for the retraction of both transverse and longitudinal nails, facilitating the removal of the entire composite pile. Furthermore, the retraction of the transverse nail automatically cleans away dirt and impurities from its surface, preventing corrosion and ensuring good recyclability.

[0022] 2. In this invention, when an earthquake occurs, the composite pile body moves with the ground vibration. When the composite pile body moves left and right, the central column can reduce vibration in the horizontal direction under the action of the spring damper. When the central column moves up and down, the slider is pushed by the second connecting rod to reduce vibration in the vertical direction. This can play a shock absorption and buffering role for the entire composite pile body, thereby avoiding damage to the composite pile body when vibration occurs and extending the service life of the entire composite pile body.

[0023] 3. In this invention, external hoisting equipment is used to connect the mounting hole and the disc. During drilling, personnel can manually rotate the second threaded rod to move the threaded block left and right, thereby using the first guide column to rotate the first sliding rod, which in turn rotates the support platform and adjusts the angle of the composite pile body so that it can be vertically aligned with the ground for drilling. This allows for a fine-tuning effect on the angle of the composite pile body when drilling into the ground, ensuring that the composite pile body can be drilled vertically into the ground, avoiding tilting of the composite pile body, and improving the installation effect.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-8 The present invention provides a technical solution:

[0036] A type of anti-settlement rigid composite pile for building construction includes a composite pile body 1, an anti-settlement mechanism on the composite pile body 1, an anti-settlement mechanism including an anti-settlement ring 33, the anti-settlement ring 33 being sleeved on the middle of the composite pile body 1 and fixedly connected thereto, longitudinal nails 32 being slidably connected to the middle of the left and right sides of the anti-settlement ring 33, and transverse nails 11 being slidably connected to the middle of the lower ends of the composite pile body 1, the anti-settlement mechanism also includes a cleaning component for cleaning the soil attached to the surface of the transverse nails 11;

[0037] The cleaning assembly includes a toothed ring 9, which is radially distributed and slidably connected to a sliding column 13. A first arc-shaped plate 14 is fixedly connected to one end of the sliding column 13 near the axis of the toothed ring 9. A brush 15 is provided on the inner side of the first arc-shaped plate 14. A fixing ring 12 is rotatably connected to the toothed ring 9, and the rear end of the fixing ring 12 is fixedly connected to the composite pile body 1.

[0038] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, a dual-axis motor 4 is fixedly connected to the middle of the inner wall of the composite pile body 1. A first threaded rod 5 is fixedly connected to the lower output end of the dual-axis motor 4. A first lifting block 6 is threadedly connected to the first threaded rod 5. The left and right sides of the front end face of the first lifting block 6 are rotatably connected to the first connecting rod 10 through the pin shaft. The lower end of the first connecting rod 10 is rotatably connected to the transverse nail 11 through the pin shaft.

[0039] The first lifting block 6 has racks 7 fixedly connected to both ends of the left and right sides. The racks 7 are slidably connected to limit rods 8. The lower end of the limit rods 8 is fixedly connected to the composite pile body 1. The racks 7 and the gear rings 9 mesh with each other.

[0040] A second spring 39 is fitted on either side of the sliding column 13. The upper and lower ends of the second spring 39 are fixedly connected to the gear ring 9 and the second arc plate 34, respectively.

[0041] A first rotating shaft 25 is fixedly connected to the upper output end of the dual-shaft motor 4. A first bevel gear 26 is sleeved and fixedly connected to the upper end of the first rotating shaft 25. A second rotating shaft 28 is rotatably connected to the middle of the left and right ends of the upper side of the composite pile body 1. A second bevel gear 27 is sleeved and fixedly connected to the ends of the second rotating shaft 28 that are close to each other. The second bevel gear 27 meshes with the first bevel gear 26. A second sliding rod 29 is sleeved and fixedly connected to the left and right ends of the second rotating shaft 28. The second sliding rod 29 is embedded in the second guide post 30 and slidably connected to it. A second lifting block 31 is fixedly connected to the ends of the second guide post 30 that are far apart from each other. A longitudinal nail 32 is fixedly connected to the lower end face of the second lifting block 31. The longitudinal nail 32 is slidably connected to the anti-sinking ring 33.

[0042] Specifically, after the composite pile body 1 is drilled into the soil, the dual-axis motor 4 is started. Under the action of the lower output end of the dual-axis motor 4, the first threaded rod 5 rotates, which causes the first lifting block 6 to descend. When the first lifting block 6 descends, the movement of the first connecting rod 10 drives the transverse nails 11 on both sides to slide in opposite directions simultaneously, so that the transverse nails 11 are inserted into the soil for transverse fixation. Then, under the action of the upper output end of the dual-axis motor 4, the first rotating shaft 25 rotates, which causes the first bevel gear 26 to rotate, which in turn causes the second bevel gears 27 on the left and right sides to rotate, which in turn causes the second sliding rods 29 on the left and right sides to rotate, and drives the second guide column 30 and the second lifting block 31 to move downward, so that the longitudinal nail 32 is inserted into the soil, completing the secondary tightening, which can prevent the composite pile body 1 from settling. At the same time, when it is necessary to remove the composite pile body 1, simply reverse the dual-axis motor 4 to raise the first lifting block 6, which will cause the transverse nails 11 and the longitudinal nails 32 to retract, canceling the tightening, so that the composite pile body 1 can be easily removed. At the same time, when the transverse nails 11 are lowered, the first lifting block 6 is raised, which will cause the transverse nails 11 and the longitudinal nails 32 to retract, canceling the tightening, so that the composite pile body 1 can be easily removed. When nail 11 retracts, the first lifting block 6 moves the rack 7, causing the gear ring 9 to rotate. The gear ring 9 then rotates the second arc plate 34. Simultaneously, under the action of the second spring 39, the second arc plate 34 uses the brush 15 to remove the mud and impurities adhering to the surface of the transverse nail 11. Under the action of the second spring 39, the brush 15 remains in close contact with the surface of the transverse nail 11, thus cleaning all positions of the transverse nail 11. This prevents corrosion caused by mud and impurities adhering to the surface of the transverse nail 11, which would affect its reuse. This provides an anti-settlement effect for the entire composite pile body 1, preventing the composite pile body 1 from sinking into the soil. It has good stability. Furthermore, it can retract the transverse nail 11 and the longitudinal nail 32, making it easier to remove the entire composite pile body 1. Moreover, when the transverse nail 11 retracts, it automatically cleans the mud and impurities adhering to its surface, preventing impurities from corroding the surface of the transverse nail 11 and affecting its subsequent reuse. It has good recycling effect.

[0043] In this embodiment, as Figure 1 and Figure 6 As shown, it also includes a central column 3 and a shock-absorbing mechanism for buffering the central column 3;

[0044] The damping mechanism includes a slider 37, which is symmetrically distributed on the upper sides of the left and right ends of the composite pile body 1 and slidably connected to them. A first spring 36 is fixedly connected to the upper end of the slider 37, and the upper end of the first spring 36 is fixedly connected to the composite pile body 1. A second connecting rod 38 is rotatably connected to the middle of the slider 37 through a pin, and a central column 3 is rotatably connected to the lower end of the second connecting rod 38 through a pin.

[0045] A support platform 2 is fixedly connected to the upper end of the central column 3. Spring dampers 35 are fixedly connected to both the left and right ends of the upper side of the inner wall of the composite pile body 1. A second arc plate 34 is fixedly connected to the piston end of the spring damper 35.

[0046] Specifically, during an earthquake, the composite pile body 1 moves with the ground vibration. When the composite pile body 1 moves left and right, the central column 3, under the action of the spring damper 35, can reduce vibration in the horizontal direction. Furthermore, when the central column 3 moves up and down, the second connecting rod 38 pushes the slider 37 to move, causing the central column 3 to reduce vibration in the vertical direction. This provides a shock absorption and buffer effect for the entire composite pile body 1, thereby preventing damage to the composite pile body 1 during vibration and extending the service life of the entire composite pile body 1.

[0047] In this embodiment, as Figure 4 As shown, the upper end of the support platform 2 is also equipped with an adjustment mechanism for easy installation;

[0048] The adjustment mechanism includes a disc 16. A mounting plate 17 is fixedly connected to the middle of the upper surface of the disc 16. The upper end of the mounting plate 17 is provided with multiple mounting holes 18. A connecting plate 24 is fixedly connected to the middle of the lower surface of the disc 16. The lower end of the connecting plate 24 is rotatably connected to the support platform 2 via a pin. A first sliding rod 22 is fixedly connected to the connection between the connecting plate 24 and the support platform 2 via a pin. A first guide post 23 is embedded in the first sliding rod 22 through a groove and slidably connected to it. A threaded block 21 is fixedly connected to the rear end face of the first guide post 23. A second threaded rod 20 is threadedly connected to the upper side of the threaded block 21. Both ends of the second threaded rod 20 are rotatably connected to the disc 16. A sliding rod 19 is slidably connected to the lower side of the threaded block 21. Both ends of the sliding rod 19 are fixedly connected to the disc 16.

[0049] Specifically, by using external hoisting equipment, the connection between the mounting hole 18 and the disc 16 is completed. During the drilling process, personnel can manually rotate the second threaded rod 20 to drive the threaded block 21 to move left and right laterally. This allows the first guide column 23 to drive the first sliding rod 22 to rotate, thereby rotating the support platform 2 and adjusting the angle of the composite pile body 1 so that it can be vertically aligned with the ground for drilling. This provides a fine-tuning effect on the angle of the composite pile body 1 when drilling into the ground, ensuring that the composite pile body 1 can be drilled vertically into the ground and avoiding tilting of the composite pile body 1, thus improving the installation effect.

[0050] Working principle of this invention: In use, external hoisting equipment is used to connect the mounting hole 18 and the disc 16. During drilling, personnel can manually rotate the second threaded rod 20 to move the threaded block 21 laterally, which in turn allows the first guide column 23 to rotate the first sliding rod 22, thus rotating the support platform 2 and adjusting the angle of the composite pile body 1 so that it is vertically aligned with the ground for drilling. This allows for fine-tuning of the angle of the composite pile body 1 as it enters the ground, ensuring it is vertical and preventing tilting, thus improving the installation effect. After the composite pile body 1 is drilled into the soil, the... The dual-axis motor 4, driven by its lower output end, rotates the first threaded rod 5, causing the first lifting block 6 to descend. As the first lifting block 6 descends, the movement of the first connecting rod 10 drives the transverse nails 11 on both sides to slide simultaneously in opposite directions, inserting them into the soil for lateral fixation. Then, driven by the upper output end of the dual-axis motor 4, the first rotating shaft 25 rotates, causing the first bevel gear 26 to rotate, which in turn rotates the second bevel gears 27 on both sides. This rotates the second sliding rods 29 on both sides, driving the second guide column 30 and the second lifting block 31 to move downwards, allowing the longitudinal nail 32 to insert into the soil, completing the process. Secondary tightening prevents settlement of the composite pile body 1. Simultaneously, when dismantling the composite pile body 1 is required, simply reverse the dual-axis motor 4 to raise the first lifting block 6, causing the transverse nail 11 and longitudinal nail 32 to retract, thus releasing the tightening and facilitating dismantling of the composite pile body 1. Simultaneously, as the transverse nail 11 retracts, the first lifting block 6 moves the rack 7, causing the gear ring 9 to rotate. The gear ring 9 then rotates the second arc-shaped plate 34. Simultaneously, under the action of the second spring 39, the second arc-shaped plate 34 uses the brush 15 to remove dirt and impurities adhering to the surface of the transverse nail 11. The brush 15 remains in contact with the transverse nail 11 under the action of the second spring 39. The surface is tightly adhered, allowing for cleaning of all positions of the transverse nail 11. This prevents corrosion caused by soil and impurities adhering to the surface of the transverse nail 11, thus affecting its reuse. This provides an anti-settlement effect for the entire composite pile body 1, preventing it from sinking into the soil. It has good stability. Furthermore, it has a retraction effect on the transverse nail 11 and the longitudinal nail 32, making it easier to remove the entire composite pile body 1. When the transverse nail 11 retracts, it automatically cleans the soil and impurities adhering to its surface, preventing impurities from corroding the surface of the transverse nail 11 and affecting its subsequent reuse. It has good recycling effect.During an earthquake, the composite pile body 1 moves with the ground vibration. When the composite pile body 1 moves left and right, the central column 3, under the action of the spring damper 35, can absorb vibration in the horizontal direction. Furthermore, when the central column 3 moves up and down, the second connecting rod 38 pushes the slider 37 to move, causing the central column 3 to absorb vibration in the vertical direction. This provides a shock-absorbing buffer for the entire composite pile body 1, thus preventing damage during vibrations and extending the service life of the entire composite pile body 1.
