Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a rapid detection device for pile foundation integrity. Background Technology

[0002] A pile foundation consists of piles embedded in the soil and pile caps connected to the pile tops. Its function is to transfer loads to deeper bearing strata to meet the bearing capacity requirements of foundations in projects such as high-rise buildings, ports, and bridges. The integrity of the pile foundation directly affects the safety and stability of the building. Rapid detection devices can promptly identify potential defects and problems in the pile foundation, such as cracks and voids, allowing for appropriate reinforcement or repair measures to ensure project quality.

[0003] Install the detection components, set the parameters, clean the site, and ensure safety. Then, the vibration equipment applies force to the top of the pile to generate stress waves, and the sensors receive the reflected signals. Next, the characteristics of the reflected waves are analyzed to determine the integrity of the pile and pinpoint the location of defects. Finally, the data is recorded and a detailed report is written to provide a basis for engineering construction. This operation must be carried out by qualified personnel according to regulations.

[0004] In existing technologies, some pile foundation integrity testing devices require signal transmission via cables between the testing device and sensors, data acquisition systems, etc. The haphazard arrangement of these cables is susceptible to external interference, leading to unstable signal transmission and reduced testing efficiency. Therefore, to address these shortcomings, a rapid pile foundation integrity testing device is proposed to solve these problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1 to 3 This utility model provides an embodiment of a rapid pile foundation integrity detection device, comprising a detector housing 1, a pile foundation 2, and a connecting line 3. The detector housing 1 is prior art and will not be described in detail. The detector housing 1 and the connecting line 3 are electrically connected via the connecting line 3. The connecting line 3 achieves electrical connection with the internal circuitry of the detector housing 1 through internal metal wires, thereby enabling the smooth transmission of detection data to the detector housing 1 for processing and analysis. Two support plates 4 are fixedly connected to the rear side of the detector housing 1, secured by welding, thus providing support for the support plates 4. A connecting plate 5 is fixedly connected to the adjacent side of the two support plates 4, also secured by welding, thus providing support for the connecting plate 5. Two sliding plates 6 are slidably connected to the outside of the connecting plate 5, allowing the two sliding plates 6 to slide stably due to the constraint of the connecting plate 5. The distant sides of the two sliding plates 6 respectively contact the adjacent sides of the two support plates 4, thus providing a limit for the sliding plates 6. Square openings 7 are provided on both the upper and lower sides of the sliding plates 6, providing space for the connecting line 3 to be routed.

[0035] Connecting rods 8 are fixedly connected to the opposite sides of the two sliding plates 6, causing the connecting rods 8 to slide synchronously as the sliding plates 6 slide. The outer sides of the connecting rods 8 are slidably connected to the inner wall of the support plate 4, allowing the connecting rods 8 to slide stably. Limiting discs 9 are fixedly connected to the opposite sides of the two connecting rods 8, providing support and preventing them from slipping. Springs 10 are fitted around the outside of the connecting rods 8, ensuring even force distribution. The opposite sides of the two support plates 4 are fixedly connected to the adjacent ends of the two springs 10, ensuring even force distribution. The opposite ends of the two springs 10 are fixedly connected to the adjacent sides of the two limiting discs 9. During sliding, the limiting discs 9 compress the springs 10, allowing them to store elastic potential energy, which then provides a counterforce to the limiting discs 9 for resetting.

[0036] Reference Figures 4 to 6A connecting cylinder 14 is slidably connected to the inner wall of the pile foundation 2. The connecting cylinder 14 is stably slidable due to the constraint of the pile foundation 2. An inspection head 11, which is a speed sensor, is fixedly connected inside the connecting cylinder 14. A limit assembly is fixedly connected to the top of the inspection head 11. The limit assembly includes a fixed cylinder 12, which is fixedly connected to the top of the inspection head 11 via welding, thus providing support for the inspection head 11. A limit block 13 is fixedly connected to the outside of the fixed cylinder 12. The bottom side of the limit block 13 contacts the top side of the pile foundation 2, providing support for the fixed cylinder 12 by engaging the limit block 13 on the pile foundation 2. The limit block 13 is slidably connected to the inside of the pile foundation 2, allowing it to slide stably due to the constraint of the pile foundation 2. A sealing ring 15, made of rubber, is fixedly connected to the outside of the connecting cylinder 14.

[0037] Limit openings 16 are provided on both the left and right sides of the connecting cylinder 14, allowing for internal movement. Two springs 17 are fixedly connected to the inner walls of both ends of the connecting cylinder 14, ensuring even force distribution. Limit plates 18 are fixedly connected to the outside of the two springs 17. During sliding, the limit plates 18 compress the springs 17, allowing them to store elastic potential energy and subsequently exert a force in the opposite direction on the limit plates 18 for resetting. V-shaped plates 19 are fixedly connected to the opposite sides of the two limit plates 18 via welding, providing support for the V-shaped plates 19.

[0038] A fixed plate 20 is fixedly connected to the bottom side of the limiting plate 18, and the sliding force is transmitted to the fixed plate 20 through the limiting plate 18. The two fixed plates 20 are slidably connected to the left and right ends of the connecting cylinder 14, respectively. The connecting cylinder 14 restricts the fixed plates 20 so that they can slide stably. An arc-shaped block 21 is fixedly connected to the opposite side of each of the two fixed plates 20. The fixed plates 20 drive the arc-shaped blocks 21 to slide synchronously during the sliding process. The opposite side of the two arc-shaped blocks 21 contacts the outside of the sealing ring 15. The arc-shaped blocks 21 press against the sealing ring 15, causing the sealing ring 15 to be deformed by the force, thereby tightly fitting against the inner wall of the pile foundation 2. A cavity 22 is opened inside the pile foundation 2 to provide space for the sealing ring 15 to move.

[0039] Working principle: First, a cavity 22 is opened inside the pile foundation 2. Then, the connecting line 3 wrapped around the two sliding plates 6 is removed. When the connecting line 3 is wrapped around the two square openings 7, it will push the two sliding plates 6 to slide towards the same side, thereby driving the connecting rod 8 to slide along the connecting plate 5. Then, the connecting rod 8 will drive the limiting plate 9 to slide and squeeze the spring 10, so that the spring 10 can store elastic potential energy, and then give the sliding plates 6 a force in the opposite direction, so that the two sliding plates 6 are subjected to a force towards the opposite side to expand the support of the wrapped connecting line 3. According to the requirements, the required length of connecting line 3 is placed, and the rest is left on the two sliding plates 6 to avoid excessive length and entanglement with external objects, thereby improving detection efficiency.

[0040] Then, the inspection head 11 is placed in the opened cavity 22. During the placement process, the sealing ring 15 will squeeze the pile base 2, making it fit against the pile base 2 to prevent external dust from entering and affecting the accuracy of the test. During the placement process, the pile base 2 will also press against the two V-shaped plates 19, causing the two V-shaped plates 19 to drive the limiting plate 18 to slide to the same side and press the two springs 17. Then the springs 17 will store elastic potential energy and then give the V-shaped plates 19 a force in the opposite direction, so that the V-shaped plates 19 can press against the pile base 2, thereby improving the stability of the test. During the sliding of the limiting plate 18, it will also drive the fixing plate 20 to slide, and during the reset process, it will drive the arc block 21 to reset and press against the arc block 21, so that the arc block 21 can be squeezed and deformed to fit tightly against the inner wall of the pile base 2, thereby improving the accuracy of the test.

[0041] The pile foundation 2 is then vibrated using a hammer or hand hammer. The signal generated by the vibration is received by the inspection head 11 and transmitted to the detector housing 1 via the connecting line 3. After each vibration, the waveform displayed on the detector housing 1 is observed to ensure that the waveform is clear and stable. If the waveform is not ideal, the vibration force or position can be adjusted or the vibration equipment can be replaced, and the vibration can be repeated.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
