Description

A pile structure positioning device with local resonance unit and its forming construction method Technical Field

[0001] This invention belongs to the field of engineering pile technology, specifically relating to a pile structure positioning device with local resonance unit and a forming construction method. Background Technology

[0002] As part of the building structure, engineering piles are formed by reinforcing cages and poured concrete, and can generally be considered the foundation of a building structure. In pile foundations, engineering piles bear the majority of the loads transmitted from the superstructure. When ground vibrations occur, the vibrations transmitted upwards through the piles can affect the safety and comfort of the building. Therefore, vibration isolation and damping structures are needed. However, existing technologies have the following problems:

[0003] 1. Existing technologies often use vibration isolation bearings to position engineering piles for vibration isolation and reduction. However, this method is not suitable for high-rise buildings with excessive upper loads, and the construction of the corresponding vibration isolation bearings is quite difficult.

[0004] 2. The existing positioning devices for engineering piles have structural defects, which can cause positional deviations during construction and affect the vibration isolation effect.

[0005] 3. In existing technologies, vibration isolation trenches or vibration isolation barriers are generally used as vibration isolation measures for building foundations. Due to the influence of the structure of the engineering piles themselves, these measures are difficult to achieve vibration isolation in the low frequency band. Summary of the Invention

[0006] This invention provides a pile structure positioning device with local resonance unit and a forming construction method to solve the problems existing in the prior art.

[0007] In a first aspect, the present invention provides a pile structure positioning device with a local resonance unit, which is disposed at the opening of a groove. The pile structure positioning device includes a fixing ring, a positioning ring, a connecting plate, an adjusting cylinder, and a force-bearing plate. A reinforcing cage is disposed in the groove, and the fixing ring is centrally disposed at the top of the reinforcing cage. The positioning ring is disposed inside the fixing ring, and the outer diameter of the positioning ring is smaller than the inner diameter of the fixing ring. Multiple connecting plates extend vertically into the depth of the groove and are fixedly connected to the bottom side of the positioning ring. The adjusting cylinder is disposed on the outer wall of the connecting plate. The force-bearing plate is disposed at the telescopic end of the adjusting cylinder and abuts against the inner wall of the reinforcing cage.

[0008] Through the above technical solution, the positioning ring is used to position the local resonant unit. Since the inner diameter of the fixed ring is larger than the outer diameter of the positioning ring, the fixed ring will not interfere with the radial movement of the positioning ring within a certain range. The position of the positioning ring relative to the center of the excavated groove or the steel cage can be adjusted and corrected by adjusting the cylinder. Therefore, the pile structure positioning device designed by the method of the present invention can ensure the placement accuracy of the local resonant unit and avoid the impact of position deviation on the vibration reduction effect.

[0009] Preferably, it further includes a placement component, a connecting plate, a spring, and a guide rod; multiple placement components are evenly arranged around the positioning ring, the first end of the placement component is fixedly connected to the fixing ring, the bottom surface of the second end of the placement component abuts against the top of the positioning ring and faces the center of the positioning ring; two mutually spaced vertical plates are provided on the top side of the second end of the placement component, the connecting plate is rotatably connected between the two vertical plates, and the middle part of the guide rod is fixedly connected to the connecting plate; one end of the spring is fixedly connected to the end of the guide rod near the inner wall of the positioning ring, and the other end is fixedly connected to the inner wall of the positioning ring.

[0010] To achieve rapid positioning of the local resonance unit during placement using the above technical solution, this invention employs a guide rod rotatably mounted on the placement component, with a spring at the lower end of the guide rod, causing it to tilt upwards and thus increasing the receiving range. Furthermore, after the local resonance unit passes the guide rod, it will return to its original position because the guide rod is rotatably connected to the placement component.

[0011] Preferably, guide wheels are rotatably connected to both ends of the guide rod.

[0012] By using the above technical solution, and by setting guide wheels on the guide rod, the rotation of the guide wheels during the lowering of the local resonance unit can avoid mutual friction and wear between components.

[0013] Preferably, two fixing cylinders are fixedly installed on the bottom side of the fixing ring. The telescopic ends of the two fixing cylinders are opposite to each other along the same inner ring diameter of the fixing ring. The telescopic ends of the fixing cylinders are fixedly connected to abutting plates for abutting against the wall of the chiseled groove.

[0014] In order to prevent the fixed ring from moving relative to the adjusting cylinder when adjusting the position of the positioning ring, the present invention uses a fixed cylinder to extend so that two abutting plates simultaneously abut against the groove wall of the chiseled groove, thereby fixing the fixed ring.

[0015] Preferably, the outer peripheral wall of the fixing ring is provided with a suspension device.

[0016] The above technical solution facilitates the rapid loading and unloading of the pile structure positioning device of the present invention.

[0017] Preferably, the suspension device includes multiple sets of lifting rings, a sliding groove formed on the outer peripheral wall of the fixed ring, and multiple connecting blocks. The connecting blocks are slidably connected to the sliding grooves, and the ends of the lifting rings are rotatably connected to the connecting blocks.

[0018] With the above technical solution, in order to make suspension more convenient, the lifting ring is fixedly connected to the fixed ring by the connecting block, and the lifting ring can be suspended at any angle.

[0019] Preferably, a positioning post is fixedly provided at one end of the lifting ring near the fixed ring, and a positioning hole is provided on the outer peripheral wall of the fixed ring. The positioning hole is located on the top side of the sliding groove, and the positioning post is selectively inserted into the positioning hole.

[0020] With the above technical solution, since the connecting block is slidably connected to the fixed ring, in order to prevent slippage during suspension, a positioning pin is inserted into the positioning hole during suspension, thereby avoiding slippage of the connecting block.

[0021] Secondly, the present invention also provides a method for forming and constructing a pile structure with local resonance units, employing the aforementioned pile structure positioning device with local resonance units, the method comprising:

[0022] S10: Use a drilling rig to excavate the weak soil layer to form a trench;

[0023] S20: First, lower the sleeve towards the opening of the groove, then lower the steel cage;

[0024] S30: After setting the pile structure positioning device towards the opening of the excavated groove, the matching multiple sets of local resonance units are positioned to the inner center of the steel cage by the pile structure positioning device with local resonance units.

[0025] S40: Pour concrete into the reinforcing cage and remove the sleeve and pile structure positioning device with local resonance unit after pouring is completed;

[0026] S50: Construction ends after the concrete has hardened.

[0027] By employing the aforementioned technical solution, excavating weak soil layers and installing reinforcing cages followed by concrete pouring significantly enhances the bearing capacity and stability of the foundation. Precisely placing local resonant units within the reinforcing cage, with concrete scattering elements inside each unit, allows the high density and mass of the concrete structure to absorb and disperse vibrational energy, thereby lowering the structure's natural frequency and increasing the difference between the structure's free vibration frequency and the external excitation frequency, thus reducing resonance. This effectively blocks the transmission of low-frequency vibration waves, significantly improving the building's vibration reduction effect and living comfort. The construction process of this invention is rationally designed, involving the installation of the sleeve, followed by the reinforcing cage, then concrete pouring, and finally the removal of the sleeve, improving construction efficiency. Furthermore, the overall structural stability and durability are enhanced, enabling it to resist external loads and deformation. Additionally, this invention is widely applicable to various geological conditions, possessing strong adaptability and flexibility, while also offering long-term vibration reduction effects and environmental and energy-saving benefits.

[0028] Preferably, the local resonance unit includes a cylindrical sleeve and multiple vertically connected damping strips; each damping strip includes a cylindrical steel shell, a concrete scattering body and a sealing gasket, the concrete scattering body is disposed inside the cylindrical steel shell, and the sealing gasket is disposed at the two ends of the cylindrical steel shell; the cylindrical sleeve encloses at least one set of damping strips.

[0029] Through the above technical solution, local resonance units are installed inside the engineering piles to block low-frequency noise. When external vibrations are transmitted to the engineering piles, such as low-frequency resonance from a subway, the concrete scattering bodies inside the local resonance units can effectively block the transmission of vibration waves in the low-frequency range, thereby improving the safety and comfort of the building.

[0030] Preferably, both ends of the cylindrical steel shell are beveled, and the bottom bevel of the cylindrical steel shell is spliced ​​to the top bevel of the adjacent cylindrical steel shell.

[0031] With the above technical solution, since the local resonance unit is composed of multiple sets of damping strips, the damping effect is low at the connection point. In this invention, by using mutually inclined surfaces, the concrete scattering body inside the damping strip can improve the damping effect at the connection point of each damping strip.

[0032] In summary, the present invention has at least one of the following beneficial technical effects:

[0033] 1. Compared with the existing technology, the present invention, by designing a special pile structure positioning device, can accurately place the local resonance unit in the middle of the steel cage, which improves the construction accuracy and ensures that the local resonance unit can play its best vibration reduction role. A fixing cylinder is set on the bottom side of the fixing ring and contacts the groove wall through the abutment plate, which effectively prevents the pile structure positioning device from moving during the adjustment process, thereby enhancing the stability of the entire construction structure.

[0034] 2. Compared with the prior art, the placement component of the pile structure positioning device of the present invention is equipped with a guide rod and a guide wheel, which enables the local resonance unit to be quickly positioned and reduces friction during the lowering process, protecting the local resonance unit and the guide rod, while improving construction efficiency.

[0035] 3. Compared with the existing technology, the method of the present invention can be widely applied to different geological conditions, has strong adaptability and flexibility, and also has long-term vibration reduction effect and environmental protection and energy-saving benefits.

[0036] 4. Compared with existing technologies, this invention also designs a unique pile structure. Based on the original steel cage + concrete pile structure, multiple sets of local resonance units are added inside the steel cage. Each set of local resonance units consists of multiple damping strips, and each damping strip contains a concrete scattering body, which can effectively block the transmission of vibration waves in the low frequency band, significantly improving the vibration reduction effect of the engineering pile, thereby improving the safety and comfort of the building. By designing the upper and lower ends of the cylindrical steel shell to be mutually inclined and spliced ​​together, the vibration reduction effect at the connection of the damping strips is enhanced, making the vibration reduction performance of the entire local resonance unit more uniform and efficient.

[0045] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0047] This embodiment discloses a pile structure positioning device with local resonance unit and a forming construction method, which is used to solve the problem that low-frequency structural vibration cannot be easily blocked in the prior art.

[0048] Example 1

[0049] As shown in Figures 1 and 2, this embodiment discloses a pile structure positioning device with a local resonance unit, which is set at the opening of the excavated groove. The pile structure positioning device includes a fixing ring 1, a positioning ring 2, a connecting plate 17, an adjusting cylinder 18, and a force-bearing plate 19.

[0050] A reinforcing cage is installed within the excavated groove, with a fixing ring 1 centrally positioned at the top of the cage. A positioning ring 2 is located inside the fixing ring 1, and its outer diameter is smaller than that of the fixing ring 1. Multiple connecting plates 17 extend vertically into the depth of the excavated groove and are fixedly connected to the bottom sides of the positioning ring 2. An adjusting cylinder 18 is located on the outer wall of the connecting plates 17. A force-bearing plate 19 is located at the extension end of the adjusting cylinder 18 and abuts against the inner wall of the reinforcing cage.

[0051] Through the above technical solution, the positioning ring 2 is used to position the local resonance unit to be deployed. The local resonance unit is a long cylinder with sound insulation and vibration reduction capabilities. Compared to existing technologies, in the pile structure positioning device of this invention, the inner diameter of the fixing ring 1 is larger than the outer diameter of the positioning ring 2. Therefore, within a certain range, the fixing ring 1 will not interfere with the radial movement of the positioning ring 2. The position of the positioning ring 2 relative to the top view center of the excavated groove or reinforcing cage can be adjusted and corrected by the adjusting cylinder 18. Therefore, the pile structure positioning device designed by this invention can ensure the placement accuracy of the local resonance unit and avoid the impact of positional deviation on the vibration reduction effect.

[0052] It should be noted that the extension length of the four adjusting cylinders 18 can be adjusted by adjusting the amount of air pumped in.

[0053] Preferably, the horizontal sidewall of the placement component 11 may be provided with scale markings.

[0054] Preferably, the abutment plate 22 is made of flexible rubber.

[0055] Furthermore, to improve the integrity of the positioning ring 2 and the fixed ring 1, expand the receiving range of the positioning ring 2, and without compromising the function of relative radial movement between the positioning ring 2 and the fixed ring 1, as shown in Figure 1, the pile structure positioning device of the present invention also includes a placement member 11, a connecting plate 14, a spring 15, and a guide rod 16. In this embodiment, the placement member 11 is L-shaped, and a total of four placement members 11 are evenly arranged around the outer peripheral wall of the positioning ring 2. One end of the placement member 11 is fixedly connected to the fixed ring 1, while the bottom surface of the other end abuts against the top of the positioning ring 2 and faces the center of the positioning ring 2. Two mutually spaced vertical plates 12 are provided on the top side of the end of the placement member 11 that abuts against the positioning ring 2. The connecting plate 14 is located between the two vertical plates 12 and rotatably connected to the two vertical plates 12. The middle part of the guide rod 16 is rotatably connected to the connecting plate 14. One end of the spring 15 is fixedly connected to the end of the guide rod 16 near the inner wall of the positioning ring 2, and the other end is fixedly connected to the inner wall of the positioning ring 2.

[0056] It should be noted that both the positioning ring 2 and the fixing ring 1 are equipped with lifting holes (not shown in the figure) and spring connection holes. When putting them into the construction site, the positioning ring 2 can be lifted first, and after the four cylinders of the positioning ring 2 are opened and pre-fixed, the fixing ring 1 can be lifted. Then, the four springs 15 are used to connect the fixing ring 1 and the positioning ring 2. Conversely, when disassembling, the operation is the opposite of the above construction plan.

[0057] Compared to existing technologies, the pile structure positioning device of the present invention, by rotatably setting a guide rod 16 on the placement member 11, and setting a spring 15 at the lower end of the guide rod 16 connected to the inner wall of the positioning ring 2, allows the guide rod 16 to tilt upwards, thereby increasing the receiving range of the positioning ring 2. After the guide rod 16 receives the local resonance unit, when the local resonance unit slides down and is placed inside the reinforcing cage under the guidance of the guide rod 16, the guide rod 16 will change from an inclined state to a vertical state during the sliding process due to the gravity of the local resonance unit itself. At this time, the local resonance unit is placed inside the reinforcing cage in a vertical state. After the local resonance unit completely detaches from the placement member 11 and enters the reinforcing cage, since the guide rod 16 is rotatably connected to the placement member 11, the guide rod 16 will automatically reset under the action of the spring 15, so as to facilitate the continuous reception of local resonance units.

[0058] Furthermore, multiple guide wheels 13 are rotatably connected to both ends of the guide rod 16.

[0059] In order to reduce friction on the guide rod 16, the guide wheel 13 is set on the guide rod 16 so that the sliding friction of the local resonance unit is changed to rolling friction during the lowering process, thereby avoiding relative friction or direct contact between the guide rod 16 and the outer side of the local resonance unit.

[0060] Furthermore, two fixing cylinders 21 are fixedly installed on the bottom side of the fixing ring 1. The telescopic ends of the two fixing cylinders 21 are opposite to each other along the same inner ring diameter of the fixing ring 1, and the telescopic ends of the fixing cylinders 21 are fixedly connected to the abutment plate 22.

[0061] It should be explained that, in order to prevent the fixed ring 1 from moving when the adjusting cylinder 18 adjusts the positioning ring 2, in this invention, after the fixed ring 1 is placed on the reinforcing cage, its two ends are fixed by adjusting the fixing cylinder 21. At the same time, to increase friction and protect the fixing cylinder 21, abutment plates 22 are fixedly provided on the output end of the fixing cylinder 21. In this embodiment, the abutment plates 22 are made of flexible rubber.

[0062] Furthermore, as shown in Figures 1 and 3, a suspension device is provided on the outer peripheral wall of the fixed ring 1. The suspension device includes multiple sets of lifting rings 3, a sliding groove 33 formed on the outer peripheral wall of the fixed ring 1, and multiple connecting blocks 34. The connecting blocks 34 are slidably connected to the sliding groove 33, and the ends of the lifting rings 3 are rotatably connected to the connecting blocks 34.

[0063] With the above technical solution, in order to make suspension more convenient, the lifting ring 3 is fixedly connected to the fixed ring 1 through the connecting block 34, and the lifting ring 3 can be suspended at any angle.

[0064] Furthermore, a positioning post 31 is fixedly installed at one end of the lifting ring 3 near the fixed ring 1, and a positioning hole 32 is opened on the outer peripheral wall of the fixed ring 1. The positioning hole 32 is located on the top side of the sliding groove 33, and the positioning post 31 is selectively inserted into the positioning hole 32.

[0065] With the above technical solution, since the connecting block 34 is slidably connected to the fixed ring 1, in order to prevent slippage during suspension, the positioning pin 31 is inserted into the positioning hole 32 during suspension, thereby avoiding the sliding of the connecting block 34.

[0066] The working principle of the pile structure positioning device of the present invention is as follows:

[0067] After placing the fixing ring 1 at the top of the reinforcing cage using the suspension device, the position of the center of the top view section of the reinforcing cage is manually determined (using a measuring instrument, ruler, etc.). Then, the precise position of the positioning ring 2 is adjusted by adjusting the cylinder 18 to determine that the positioning ring 2 is in the center of the top view section of the reinforcing cage. The local resonance unit is then lowered. After the local resonance unit is slowly lowered into the reinforcing cage, concrete is poured from the side of the excavated groove. When the bottom is filled with concrete, the cylinders are pulled back and the pile structure positioning device is detached from the reinforcing cage using the suspension device.

[0068] Example 2

[0069] This embodiment discloses a pile structure forming construction method with local resonance units, using the pile structure positioning device with local resonance units as described in Embodiment 1. The method includes:

[0070] S10: Use a drilling rig to excavate the weak soil layer to form a trench;

[0071] S20: First, lower the sleeve towards the opening of the groove, then lower the steel cage;

[0072] S30: After setting the pile structure positioning device towards the opening of the excavated groove, the matching multiple sets of local resonance units are positioned to the inner center of the steel cage by the pile structure positioning device with local resonance units.

[0073] S40: Pour concrete into the reinforcing cage and remove the sleeve and pile structure positioning device with local resonance unit after pouring is completed;

[0074] S50: Construction ends after the concrete has hardened.

[0075] Compared with existing technologies, the method of this invention can be widely applied to different geological conditions, has strong adaptability and flexibility, and also has long-term vibration reduction effect and environmental protection and energy-saving benefits.

[0076] Example 3

[0077] As shown in Figure 4, this embodiment discloses a pile structure with local resonance units, which is applied to the pile structure forming construction method with local resonance units in Embodiment 2. The pile structure includes a steel cage and a concrete structure that is poured and solidified.

[0078] As shown in Figures 5 and 6, the pile structure with localized resonance units also includes multiple sets of localized resonance units disposed inside the reinforcing cage. Each set of localized resonance units includes a cylindrical sleeve 4 and multiple vertically connected damping strips. Each damping strip includes a cylindrical steel shell 41, a concrete scattering element 43, and a sealing gasket 42. The concrete scattering element 43 is disposed inside the cylindrical steel shell 41, and the sealing gasket 42 is disposed at the two end openings of the cylindrical steel shell 41. The cylindrical sleeve 4 encloses at least one set of damping strips.

[0079] Compared to existing technologies, this invention uses a localized resonance unit inside the engineering pile to block low-frequency noise. Specifically, when external vibrations are transmitted to the engineering pile, such as low-frequency resonance from a subway, the concrete scatterer 43 inside the localized resonance unit can effectively block the transmission of vibration waves in the low-frequency range, thereby overcoming the problems of existing technologies and improving the safety and comfort of buildings around the subway.

[0080] Preferably, both ends of the cylindrical steel shell 41 are inclined surfaces, and the bottom inclined surface of the cylindrical steel shell 41 is spliced ​​to the top inclined surface of the adjacent cylindrical steel shell 41.

[0081] It should be explained that since the local resonance unit is composed of multiple sets of damping strips, the damping effect is low at the connection point. In this invention, by using mutually inclined surfaces, the concrete scattering body 43 inside the damping strip can improve the damping effect at the connection point of each damping strip.

[0082] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this invention.
