Description

Technical Field

[0001] This application relates to the field of bored pile technology, specifically a device for controlling the grouting elevation at the top of a bored pile. Background Technology

[0002] In the field of modern civil engineering, bored piles have become a commonly used foundation type in many large buildings, bridges and important infrastructure projects due to their advantages such as adaptability to various geological conditions and strong bearing capacity. The pile top grouting elevation, as a key indicator in the construction of bored piles, plays a vital role in the quality of the entire pile foundation.

[0003] An existing patent (publication number: CN220927823U) discloses a utility model providing a device for controlling the concrete elevation of the top of bored cast-in-place piles, specifically relating to the technical field of auxiliary equipment for concrete grouting. The device includes a steel reinforcement suspension beam, and further comprises: a support rod, which slides within the steel reinforcement suspension beam; an airbag ring fixed to the bottom end of the support rod; a telescopic rod fixed to the bottom end of the steel reinforcement suspension beam; a support plate fixed to the bottom end of the telescopic rod, and the support plate is slidably connected to the support rod; an alarm fixed at the center of the support plate; and drive buttons symmetrically arranged on the bottom surface of the support plate, with each symmetrical drive button connected to the alarm signal. This utility model effectively avoids the need for repeated measurements and inaccurate, timely feedback required by existing devices, facilitating timely alarm feedback and increasing the device's practicality.

[0004] The aforementioned comparative documents reveal several shortcomings in the borehole pile top concrete elevation control device. The airbag ring is significantly affected by environmental factors such as temperature and humidity, and friction with the pile hole wall generates resistance. When the concrete pushing force is low or the pile hole depth changes, causing alterations in frictional resistance, the measured liquid level height data becomes inaccurate and unstable. Under harsh working conditions, the telescopic rod is prone to corrosion and wear, resulting in poor extension and retraction and inaccurate positioning. The drive button is also prone to wear and aging, leading to poor contact, which affects the alarm signal issuance and the device's reliability, thereby impacting the construction quality of the borehole pile. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a device for controlling the grouting elevation at the top of bored cast-in-place piles. This device has the advantages of precise elevation control and improved construction quality, and solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a device for controlling the grouting elevation of the top of a bored cast-in-place pile, comprising a steel reinforcement suspension beam, two fixed frames fixedly connected to the bottom surface of the steel reinforcement suspension beam, a liquid level display fixedly connected to the bottom surface of the steel reinforcement suspension beam, a support block fixedly connected to the upper surface of one of the fixed frames, a mounting box fixedly connected to the upper surface of the support block, an alarm fixedly connected to the inner wall of the mounting box, a signal converter fixedly connected to the upper surface of the other fixed frame, a support rod fixedly connected to the bottom surface of the steel reinforcement suspension beam, a pressure sensor fixedly connected to the bottom end of the support rod, a pressure guiding pipe fixedly connected to the bottom surface of the pressure sensor, and a pressure probe fixedly connected to the bottom end of the pressure guiding pipe.

[0007] The above-described scheme, through the coordinated use of pressure probes, pressure guide pipes, signal converters, and liquid level displays, accurately senses changes in the pressure of the concrete within the cast-in-place pile. This pressure is efficiently converted into liquid level data and displayed intuitively on the liquid level display, providing construction personnel with precise real-time pouring information. This effectively ensures accurate control of the pile top pouring elevation, significantly improving the quality and efficiency of bored pile construction. The coordinated use of pressure sensors and alarms can sensitively detect abnormal pressure fluctuations. When the pressure deviates from the preset safety range, the alarm is quickly triggered, promptly alerting construction personnel to potential risks during the pouring process. This allows for rapid adjustments and adjustments, ensuring the safety and stability of the entire construction operation. The coordinated use of fixed frames and support rods securely fixes the support rods below the steel reinforcement suspension beam, preventing displacement or damage during concrete pouring due to impact or disturbance. This ensures the accuracy and continuity of measurement data, laying a solid foundation for precise control of the pile top pouring elevation.

[0008] Furthermore, the bottom surface of the steel bar suspension beam is fixedly connected to two limiting plates, and the two limiting plates are respectively fixedly connected to the outer surfaces of the two fixing frames.

[0014] Furthermore, two limiting frames are fixedly connected to the outer surface of the support rod, and the sides of the two limiting frames that are close to each other are fixedly connected to the left and right sides of the pressure sensor, respectively.

[0015] The above solution uses a limit bracket to limit the pressure sensor, preventing it from tilting or misaligning during operation.

[0016] Furthermore, a support frame is fixedly connected to the bottom surface of the steel bar suspension beam, and the inner wall of the support frame is fixedly connected to the outer surface of the protective shell.

[0018] Furthermore, a limiting ring is fixedly connected to the bottom surface of the steel bar suspension beam, and the inner wall of the limiting ring is fixedly connected to the outer surface of the support rod.

[0019] The above solution uses a limiting ring to limit the support rod, preventing it from tilting or becoming unstable during long-term operation and ensuring the stability of the device.

[0020] Furthermore, a sealing ring is fixedly connected to the bottom surface of the pressure sensor, and the inner wall of the sealing ring is fixedly connected to the outer surface of the pressure guiding tube.

[0021] The above solution uses a sealing ring to seal and protect the pressure-conducting tube, ensuring stable and accurate transmission of the pressure signal and preventing signal attenuation or distortion during transmission.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This device for controlling the grouting elevation of bored piles utilizes a pressure probe, pressure guide pipe, signal converter, and liquid level display to accurately sense pressure changes in the concrete within the pile and efficiently convert them into liquid level data displayed on the liquid level display. This provides construction personnel with precise real-time grouting information, effectively ensuring accurate control of the pile top grouting elevation and significantly improving the quality and efficiency of bored pile construction. The device also features a pressure sensor and alarm to detect abnormal pressure fluctuations. When the pressure deviates from the preset safety range, the alarm is quickly triggered, alerting construction personnel to potential risks during the grouting process and prompting them to take immediate corrective action. This ensures the safety and stability of the entire construction operation. Furthermore, the device uses a fixed frame and support rod to securely fix the support rod below the steel reinforcement suspension beam, preventing displacement or damage during concrete grouting due to impact or disturbance.

By setting the pressure probe 18, and through the cooperation of the pressure guide pipe 17, the signal converter 15, and the liquid level indicator 3, the device can accurately sense changes in the pressure of the concrete inside the bored pile and efficiently convert them. The liquid level height data is displayed intuitively on the liquid level height display 3, providing construction personnel with accurate real-time grouting information. This effectively ensures precise control of the grouting elevation at the top of the pile, greatly improving the quality and efficiency of bored pile construction. By setting up the pressure sensor 9 and the alarm 14 in cooperation, abnormal pressure fluctuations can be detected. When the pressure deviates from the preset safety range, the alarm 14 is quickly triggered to issue a warning signal, thus promptly reminding construction personnel to pay attention to potential risks in the grouting process. This prompts them to take corresponding measures for adjustment and handling, ensuring the safety and stability of the entire construction operation. By setting up the fixed frame 2 and the support rod 7 in cooperation, the support rod 7 can be firmly fixed below the steel reinforcement suspension beam 1, preventing the support rod 7 from shifting or being damaged due to impact or disturbance during concrete grouting. This ensures the accuracy and continuity of the measurement data, thus laying a solid foundation for precise control of the grouting elevation at the top of the pile.

[0032] Please see Figure 1 , Figure 2 and Figure 4Two limiting plates 6 are fixedly connected to the bottom surface of the steel reinforcement suspension beam 1. The two limiting plates 6 are fixedly connected to the outer surfaces of the two fixed frames 2 respectively. By setting the limiting plates 6, the fixed frames 2 can be limited to prevent tilting or misalignment during operation. A protective shell 4 is fixedly connected to the bottom surface of the steel reinforcement suspension beam 1. The inner wall of the protective shell 4 is fixedly connected to the outer surface of the liquid level display 3. By setting the protective shell 4, the liquid level display 3 can be protected to prevent damage during operation. The upper surface of one of the fixed frames 2 is fixed. Two fixing blocks 5 are connected, and the sides of the two fixing blocks 5 that are close to each other are fixedly connected to the left and right sides of the signal converter 15 respectively. By setting the fixing blocks 5, the signal converter 15 can be fixed, preventing the signal converter 15 from becoming unstable and falling during operation.

[0033] Please see Figure 1 , Figure 2 and Figure 4 A support frame 10 is fixedly connected to the bottom surface of the steel bar suspension beam 1. The inner wall of the support frame 10 is fixedly connected to the outer surface of the protective shell 4. The support frame 10 can support the liquid level display 3 and prevent the liquid level display 3 from tilting and falling during operation. A limit ring 11 is fixedly connected to the bottom surface of the steel bar suspension beam 1. The inner wall of the limit ring 11 is fixedly connected to the outer surface of the support rod 7. The limit ring 11 can limit the support rod 7 and prevent the support rod 7 from tilting during long-term operation, thus ensuring the stability of the device. A sealing ring 16 is fixedly connected to the bottom surface of the pressure sensor 9. The inner wall of the sealing ring 16 is fixedly connected to the outer surface of the pressure guide tube 17. The sealing ring 16 can seal and protect the pressure guide tube 17, ensuring that the pressure signal can be transmitted stably and accurately, and preventing signal attenuation or distortion during transmission.

[0034] In this embodiment, by setting up the pressure probe 18, pressure guide pipe 17, signal converter 15, and liquid level display 3 in cooperation, the pressure changes of the concrete in the cast-in-place pile can be accurately sensed and efficiently converted into liquid level data, which is then displayed intuitively on the liquid level display 3. This provides construction personnel with accurate real-time grouting information, effectively ensuring precise control of the grouting elevation at the pile top, and greatly improving the quality and efficiency of bored cast-in-place pile construction. By setting up the pressure sensor 9 and alarm 14 in cooperation, abnormal pressure fluctuations can be sensitively detected. When the pressure deviates from the pre-set value... When a safe range is established, the alarm 14 is quickly triggered to issue a warning signal, thereby promptly reminding construction personnel to pay attention to potential risks in the grouting process. This prompts them to take corresponding measures to adjust and handle the situation quickly, ensuring the safety and stability of the entire construction operation. By setting up the fixed frame 2 and the support rod 7 in cooperation, the support rod 7 can be firmly fixed below the steel reinforcement suspension beam 1, preventing the support rod 7 from shifting or being damaged due to impact or disturbance during the concrete grouting process. This ensures the accuracy and continuity of the measurement data, thus laying a solid foundation for accurately controlling the grouting elevation of the pile top.

[0035] The working principle of the above embodiments is as follows:

[0036] Firstly, when using this device, the pressure probe 18 is placed at the corresponding position in the concrete inside the pile hole according to the actual needs. As the concrete surface continues to rise or fluctuate, the concrete exerts different pressures on the pressure probe 18. The pressure probe 18 will sense the pressure changes applied by the concrete and then transmit the sensed pressure to the signal converter 15 through the pressure guide tube 17. The signal converter 15 converts the received pressure signal into a liquid level height signal and transmits this liquid level height data to the liquid level height display 3 for display. This provides construction personnel with accurate real-time grouting information, which can then be compared with the designed pile top grouting elevation to achieve control of the grouting elevation. When the pressure sensor 9 detects that the pressure has reached the preset range, it will immediately transmit the signal to the alarm 14. The alarm 14 will immediately sound an alarm to alert the construction personnel to pay attention to the current grouting status and take appropriate measures in a timely manner.
