Description

Technical Field

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

[0002] As a primary load-bearing structural component in building construction, pipe piles must withstand temporary loads such as pile driving impacts and hoisting during the construction phase, and bear the long-term vertical loads transmitted by the main building structure during the service phase. Their installation accuracy and verticality directly affect the safety and stability of the overall structure. If the pipe piles are installed with tilt or positional deviation, it can easily lead to uneven distribution of vertical loads, potentially causing localized stress concentration, structural settlement, or even overall instability. Therefore, extremely high requirements are placed on the installation accuracy and verticality control of pipe piles, making pipe pile construction a crucial link in ensuring the safety of the main structure and the safety of construction operations.

[0003] However, in existing technologies for pipe pile construction, the lack of dedicated guiding and positioning auxiliary devices makes the pipe piles susceptible to deviation or tilting due to factors such as soil resistance and pile driving impact during lowering. Furthermore, the lack of methods for detecting the verticality of the pipe piles during construction often relies on manual visual inspection, making it difficult to accurately determine their verticality. This results in installation deviations exceeding specifications. This not only affects the load-bearing performance of the pipe pile itself but may also adversely impact the quality of subsequent structural construction. Utility Model Content

[0004] The purpose of this utility model is to provide a casing for pipe pile construction, which effectively solves the technical problem that pipe piles are prone to displacement or tilting during construction in the prior art.

Detailed Implementation

[0022] To better understand the purpose, structure, and function of this utility model, the following detailed description of a pipe pile construction casing provided by this utility model is provided in conjunction with the accompanying drawings, so that those skilled in the art can better understand and implement this utility model. However, the embodiments described are not intended to limit this utility model.

[0023] Please see Figures 1 to 4 As shown in the embodiment of this application, a pipe pile construction casing is provided, including a guide cylinder 10, a pad plate 20, and a pipe pile casing 30 arranged coaxially from top to bottom; both the guide cylinder 10 and the pipe pile casing 30 are open at both ends; the guide cylinder 10 is connected to the pipe pile casing 30 through the central hole of the pad plate 20; the inner diameter of the guide cylinder 10 decreases sequentially from top to bottom, and the inner diameter of the lower end of the guide cylinder 10 is the same as the size of the central hole of the pad plate 20 and the inner diameter of the pipe pile casing 30; a plurality of horizontal measuring mechanisms 40 are arranged at equal intervals around the outer periphery of the guide cylinder 10 on the upper surface of the pad plate 20; the horizontal measuring mechanism 40 includes a horizontal ruler 41, a level 42, and two inclination measuring devices 43; the level 42 is fixed to the upper end of the horizontal ruler 41 along the length direction of the horizontal ruler 41; the two inclination measuring devices 43 are respectively embedded in the side wall of the horizontal ruler 41 along the length direction of the horizontal ruler 41, and are located on both sides of the level 42.

[0024] Because the system includes a guide cylinder 10, a base plate 20, and a pipe pile casing 30, and multiple horizontal measuring mechanisms 40 are evenly spaced around the outer periphery of the guide cylinder 10 on the upper surface of the base plate 20; each horizontal measuring mechanism 40 includes a horizontal ruler 41, a spirit level 42, and two inclination measuring devices 43, the coordinated use of these components not only provides vertical guidance for pipe pile construction but also improves the accuracy of pipe pile construction, ensuring that the verticality of the pipe pile meets construction requirements. This effectively solves the technical problem of easy deviation or tilting during pipe pile construction in existing technologies.

[0025] Specifically, the guide cylinder 10 guides the pipe pile, allowing it to smoothly enter the pipe pile casing 30 along the guide cylinder 10. The pipe pile casing 30 provides vertical guidance for impact pile driving. Simultaneously, multiple horizontal measuring mechanisms 40 are evenly spaced around the outer periphery of the guide cylinder 10 on the upper surface of the pad 20 to detect the horizontal state of the pad 20 from different directions, ensuring the verticality of the pipe pile meets construction requirements. Furthermore, the level of the pad 20 is visually judged using the bubble level 42 on the leveling block 41, and the inclination of the pad 20 is measured using two tilt measuring devices 43. This allows for adjustment of the horizontality of the pipe pile construction casing, ensuring the verticality of the casing meets the pipe pile verticality requirements, and consequently, the verticality of the pipe pile meets construction requirements. The tilt measuring device 43 includes a scale and a pointer rotatably connected to the scale. The scale has a graduation array distributed in a ring around the pointer. The pointer is rotatably connected to the scale via a rotating shaft, and the pointer includes an indicator tip and a counterweight distributed on both sides of the rotating shaft. The center of gravity of the pointer is located on the side of the counterweight so that the pointer remains vertically upward when placed vertically. The tilt angle can be obtained by pointing the indicator tip to the graduation. A notch is provided at the upper end of the horizontal ruler block 41; the spirit level 42 is fixed in the notch along the length of the horizontal ruler block 41.

[0026] In addition, in this embodiment, the guide cylinder 10 is a horn-shaped steel pipe with a thickness of 25mm, the pipe pile casing 30 is a seamless steel pipe with a thickness of 25mm, the pad plate 20 is a steel plate with a thickness of 25mm, the height of the guide cylinder 10 is 0.2m, and the height of the pipe pile casing 30 is 2m, which can ensure that the verticality deviation of the pipe pile is within the specified range.

[0027] In a preferred embodiment, the horizontal measuring mechanism 40 further includes two magnetic blocks 44 and a lifting assembly 45 for lifting the magnetic blocks 44; two magnetic chambers 41a are provided at the bottom of the horizontal ruler block 41; the two magnetic blocks 44 are respectively slidably embedded in the two magnetic chambers 41a; the lifting assembly 45 is disposed at the upper end of the horizontal ruler block 41, and the lifting rod 45d of the lifting assembly 45 slides through the horizontal ruler block 41 and is connected to the upper end of the magnetic blocks 44.

[0028] Since the horizontal measuring mechanism 40 is also equipped with two magnetic blocks 44 and a lifting component 45, and the bottom of the horizontal ruler block 41 has two magnetic chambers 41a, through the cooperation of the above components, the horizontal measuring mechanism 40 can be attracted to the pad 20 by the two magnetic blocks 44 to prevent it from shifting during construction and improve the measurement accuracy of the horizontal measuring mechanism 40. Moreover, the magnetic blocks 44 can be separated from the pad 20 by the lifting component 45, so that the construction personnel can adjust the position of the horizontal measuring mechanism 40 according to the construction needs, or remove the horizontal measuring mechanism 40 from the pad 20.

[0029] Specifically, when it is necessary to adjust the position of the horizontal measuring mechanism 40 or to remove the horizontal measuring mechanism 40, the lifting rod 45d of the lifting assembly 45 is lifted and moved upward relative to the horizontal ruler block 41 by lifting the lifting assembly 45. At the same time, the magnetic block 44 is moved upward in the magnetic chamber 41a so that the magnetic block 44 is away from the pad 20. This allows the horizontal measuring mechanism 40 to be moved or removed from the pad 20.

[0030] In a preferred embodiment, the lifting assembly 45 includes a grip plate 45a, a lifting plate 45b, two springs 45c, and two lifting rods 45d. The grip plate 45a is located above the bubble level 42, and its two ends are respectively connected to the upper sides of the horizontal ruler block 41. Two guide rods 45e are provided at the bottom of the grip plate 45a, and the two guide rods 45e are respectively located on both sides of the bubble level 42, and their lower ends are respectively connected to the horizontal ruler block 41. The lifting plate 45b is located between the grip plate 45a and the horizontal ruler block 41, and its two ends are respectively slidably connected to the two guide rods 45e. The two ends of the two springs 45c are respectively connected to the grip plate 45a and the lifting plate 45b, and the two springs 45c are respectively sleeved on the two guide rods 45e. The two lifting rods 45d are respectively fixed below the lifting plate 45b, and their lower ends slide through the horizontal ruler block 41 and are connected to the upper end of the magnetic block 44.

[0031] Because the lifting assembly 45 is equipped with a gripping plate 45a, a lifting plate 45b, two springs 45c, and two lifting rods 45d, and two guide rods 45e are provided at the bottom of the gripping plate 45a, the magnetic block 44 can be easily attracted to or detached from the pad 20 through the cooperation of the above components, so as to adjust the position of the horizontal measuring mechanism 40 or remove the horizontal measuring mechanism 40 from the pad 20. In use, the construction personnel can grip the lifting plate 45b with the gripping plate 45a to move the lifting plate 45b upward. At this time, the springs 45c are squeezed, and the lifting rods 45d move upward under the action of the lifting plate 45b, which at the same time drives the magnetic block 44 to move upward relative to the magnetic chamber 41a, thereby causing the magnetic block 44 to detach from the pad 20. When the lifting plate 45b is released, the spring 45c resets, causing the lifting plate 45b to move downwards, and simultaneously moving the lifting rod 45d and the magnetic block 44 until the spring 45c resets, at which point the lower end of the magnetic block 44 is flush with the bottom of the horizontal ruler 41, allowing it to adhere to the pad 20. The horizontal ruler 41 has a through hole extending from top to bottom on both sides of the level bubble 42 for inserting the lifting rod 45d, and this through hole communicates with the magnetic chamber 41a. Two guide rods 45e guide the vertical movement of the lifting plate 45b, ensuring smooth vertical movement along the guide rods 45e and preventing deviation during movement. The depth of the magnetic chamber 41a is greater than the thickness of the magnetic block 44, allowing the magnetic block 44 to move vertically relative to the magnetic chamber 41a.

[0032] In a preferred embodiment, the outer peripheral wall of the guide cylinder 10 is provided with a plurality of evenly distributed first reinforcing ribs 11 connected to the pad 20; the horizontal measuring mechanism 40 is located on one side of the first reinforcing ribs 11.

[0033] Because the outer peripheral wall of the guide cylinder 10 is provided with multiple evenly distributed first reinforcing ribs 11, it can not only enhance the connection strength between the guide cylinder 10 and the pad 20, preventing relative displacement or deformation between the two when the pipe pile is under stress, but also further ensure the coaxiality stability of the guide cylinder 10, the pad 20 and the pipe pile casing 30, ensuring the guiding accuracy and the accuracy of horizontal measurement. Specifically, in this embodiment, the outer peripheral wall of the guide cylinder 10 is provided with eight first reinforcing ribs 11.

[0034] In a preferred embodiment, a hoisting hole 11a is provided at the center of gravity of the first reinforcing rib 11. By providing a hoisting hole 11a at the center of gravity of the first reinforcing rib 11, a force-bearing point can be provided for hoisting, facilitating the handling and installation of the casing for the pipe pile construction.

[0035] In a preferred embodiment, the outer peripheral wall of the pipe pile casing 30 is provided with a plurality of evenly distributed second reinforcing ribs 31 that are connected to the pad plate 20.

[0036] Because the outer peripheral wall of the pipe pile casing 30 is provided with multiple evenly distributed second reinforcing ribs 31, the connection stability between the pad 20 and the pipe pile casing 30 can be strengthened while improving the penetration capability of the pipe pile casing 30, so that the pipe pile casing 30 can penetrate the ground. Specifically, in the embodiment of this application, the outer peripheral wall of the pipe pile casing 30 is provided with four second reinforcing ribs 31.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
