Description

Technical Field

[0001] The invention belongs to the technical field of soil pile testing, in particular to a device for synchronously testing the soil penetration depth and ultimate bearing capacity of a full-size static soil-squeezing pile. Background Art

[0002] Pile foundations, as a crucial foundation form in various construction projects, play a crucial role in transferring superstructure loads to the deep subsoil. Accurately assessing the bearing capacity and penetration depth of pile foundations is crucial for ensuring building safety and stability. During pile foundation construction, it's crucial to understand the mechanical properties of the soil-squeezing piles during penetration and their ultimate bearing capacity to provide accurate data support for project design and construction.

[0003] A Chinese invention patent publication numbered CN102011389A discloses an in-situ testing device for rock and soil. The device comprises a steel pipe shaped like a pile, with a pile tip plate and a first pressure sensor for sensing the pressure applied to the pile tip plate disposed at one end of the pipe. The pile tip plate is perpendicular to the sidewall of the pipe. One or more sidewall friction cylinders are disposed radially along the pipe, and each sidewall friction cylinder is provided with a second pressure sensor for sensing the friction applied thereto. The sidewall friction cylinders form a portion of the pipe's sidewall. A portion of the pipe's sidewall is configured as a movable side pressure plate, and a third pressure sensor is provided for sensing the pressure applied to the side pressure plate. A pore water pressure gauge and a camera are disposed within the pipe's sidewall.

The device can measure and read a variety of data, facilitating accurate analysis of soil properties. The invention also discloses a method for conducting on-site in-situ testing using the device.

[0004] However, the above technologies often have the following defects: the equipment fails to achieve simultaneous and accurate monitoring of the depth of burial and the ultimate bearing capacity. In actual projects, changes in the depth of the pile directly affect the stress distribution and bearing performance of the soil around the pile. However, this technology can only obtain single-dimensional data separately, and it is difficult to intuitively present the real-time evolution of the bearing capacity at different burial depths, and it is difficult to meet the project's needs for refined and coordinated testing.

The upper end of the conical sleeve extends into the inner arc surface of the sleeve. The inner arc surface of the cap sleeve is penetrated and connected with a concrete pile. The outer arc surface of the concrete pile is provided with a pile section.

[0011] A metering assembly is fixedly installed in the middle of the upper surface of the bearing support plate. The metering assembly includes a base fixedly installed on the upper surface of the bearing support plate. A reference column is connected through the upper surface of the base. A main shaft is connected through the upper surface of the reference column.

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0037] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the embodiment of the present invention includes a support frame 1, which is composed of two horizontal rectangular plates and two longitudinal rectangular plates. The upper surface of the longitudinal rectangular plate on one side of the support frame 1 is fixed with a bearing support plate 2 by bolts. A side edge of the upper surface of the bearing support plate 2 is provided with a panel 21. A partition 22 is provided between the bearing support plate 2 and the panel 21. A collar base 23 is provided in the middle of one side of the horizontal end surface of the bearing support plate 2. The inner arc surface of the collar base 23 is penetrated and connected with a monitoring component 3. The monitoring component 3 includes a movable sleeve connected to the collar. The inner arc surface of the base 23 is provided with a protective tube 31, and the inner arc surface of the protective tube 31 is movably connected to the sleeve 32. The top of the inner arc surface of the sleeve 32 is provided with a limit platform 321. The inner arc surface of the limit platform 321 movably abuts against the stress kit 33. The top of the inner arc surface of the stress kit 33 is provided with a groove 331. The inner arc surface of the stress kit 33 is sleeved with an inlet cap sleeve 34. The upper surface of the inlet cap sleeve 34 is provided with an upper edge end 341. The outer arc surface of the inlet cap sleeve 34 is provided with an outer convex end 342. The outer arc surface of the outer convex end 342 movably abuts against the inner arc surface of the groove 331.

[0038] A bent end 332 is provided on the lower surface of the stress kit 33, and a gap is provided between the bent end 332 and the limit platform 321. A tension sleeve 35 is movably sleeved in the gap between the bent end 332 and the limit platform 321. The upper end surface of the tension sleeve 35 is provided with a filling end 351, and the inner arc surface of the tension sleeve 35 is provided with an inner concave surface 352. The bottom end of the outer arc surface of the sleeve 32 is sleeved with an anti-interference ring 36, and a photoelectric displacement sensor 37 is connected between the anti-interference ring 36 and the sleeve 32. The inner arc surface of the anti-interference ring 36 abuts against a conical sleeve 38, and the upper end of the conical sleeve 38 extends to the inner arc surface of the sleeve 32. The inner arc surface of the cap sleeve 34 is penetrated and connected with a concrete pile 4, and the outer arc surface of the concrete pile 4 is provided with a pile section 41.

[0039] The support frame 1 is placed at a suitable location on the test site using the positioning links 6, side panels 7, and moving wheels 8. The pulley assembly 9 of the moving wheels 8 allows for flexible movement and positioning. By adjusting the moving wheels 8, the support frame 1 remains horizontal and stable, ensuring the accuracy of subsequent test data. The casing 31 is flexibly sleeved onto the inner curved surface of the collar base 23. The casing 31 protects the internal structure and guides the sleeve 32.

[0040] Put the sleeve 32 into the inner arc surface of the casing 31. The limit platform 321 on the sleeve 32 is used to limit the position of the stress kit 33. Put the stress kit 33 into the sleeve 32 so that a gap is reserved between the bent end 332 and the limit platform 321 for installing the tension sleeve 35. The groove 331 of the stress kit 33 is movably abutted with the outer protruding end 342 of the cap sleeve 34 to ensure the stable installation of the cap sleeve 34. Install the tension sleeve 35 in the gap between the bent end 332 and the limit platform 321. 5, its filling end 351 and inner concave surface 352 can effectively transmit and disperse stress. The anti-interference ring 36 is sleeved on the bottom end of the outer arc surface of the sleeve 32. A photoelectric displacement sensor 37 is installed between the anti-interference ring 36 and the sleeve 32 to measure the depth of penetration into the soil. The inner arc surface of the anti-interference ring 36 abuts against the conical sleeve 38, which further protects and positions the internal structure. The concrete pile 4 is passed through the inner arc surface of the cap sleeve 34. The pile section 41 of the concrete pile 4 is used to contact the soil and transmit the load.

[0041] At the full-size steel pipe pile prototype test site, when the concrete pile 4 is gradually sunk into the foundation by equipment such as a hydraulic pile driver or a vibrating pile driver, the downward movement of the pile body will drive the internal monitoring component 3 to move synchronously. The sleeve 32 is tightly connected to the cap sleeve 34 and the stress kit 33, and descends together with the concrete pile 4. The anti-interference ring 36 is pre-fixed in a stable position on the support frame 1 and remains relatively still. The photoelectric displacement sensor 37 is installed between the sleeve 32 and the anti-interference ring 36. By emitting an infrared beam or a laser beam, it captures the changes in the distance between the two in real time and converts the displacement data into an electrical signal. When the sleeve 32 moves down ten centimeters with the pile body, the photoelectric displacement sensor 37 quickly senses and outputs the corresponding electrical signal, which is transmitted to the on-site data acquisition box through a shielded cable, and then uploaded to the cloud server by the wireless transmission module.

[0042] At the same time, the matching static penetration equipment starts to work together, and the probe rod is pressed into the soil at a uniform speed at a distance of thirty to fifty centimeters from the concrete pile 4. The cone head and side wall of the probe rod are respectively installed with high-precision pressure sensors 55 for measuring the cone tip resistance and side wall friction resistance. When the probe rod is buried to the same depth as the concrete pile 4, the cone tip resistance, side wall friction resistance and total pressure data at this moment are recorded. When the concrete pile 4 is five meters buried in the soil, the static penetration equipment displays the probe rod cone tip resistance and side wall friction resistance. These data can intuitively reflect the density and shear strength of the soil at this depth, and are correlated with the burial depth data collected by the photoelectric displacement sensor 37, providing a multi-dimensional basis for the subsequent analysis of pile-soil interaction.

[0043] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 8As shown, a metering assembly 5 is fixedly installed in the middle of the upper surface of the bearing support plate 2, and the metering assembly 5 includes a base 51 fixedly installed on the upper surface of the bearing support plate 2, a reference column 52 is connected through the upper surface of the base 51, a main shaft 53 is connected through the upper surface of the reference column 52, a worm 54 is fixedly installed on the outer arc surface of the main shaft 53, a pressure sensor 55 is fixedly installed on the top of the main shaft 53 near the worm 54, a wireless transmission block 56 is fixedly installed on the top of the main shaft 53, the outer arc surface of the main shaft 53 is placed on one side of the partition 22, a flange 57 is fixedly installed in the middle of one side surface of the partition 22, a transmission shaft 58 is movably connected to the surface of one side of the flange 57, one end of the transmission shaft 58 passes through the end surface of one side of the partition 22, and the transmission shaft 58 is fixed on the top of the main shaft 53. A worm gear 59 is fixedly installed at one end, and the outer arc surface of the worm gear 59 is meshed with the worm 54. A transmission shaft 58 passes through one end of the partition 22 and is fixedly installed with a gear A510. A gear B511 is fixedly installed on one side of the enclosure 21 through the transmission shaft 58. The serrations on the outer arc surface of the gear A510 are meshed with the gear B511. The outer arc surface of the worm gear 59 fits with the pile section 41 of the concrete pile 4. The pressure sensor 55 is adapted to the concrete pile 4. A positioning link 6 is passed through the surface of one side of the support frame 1, and the positioning link 6 passes through one end of the support frame 1 and is fixedly installed with a side plate 7. A moving wheel 8 is movably connected to the surface of one side of the side plate 7 through a rotating shaft. There are several moving wheels 8, and a pulley group 9 is connected between adjacent moving wheels 8.

[0044] The base 51 is fixedly installed on the upper surface of the bearing support plate 2 as the basic support of the metering component 5, and the reference column 52 passes through the upper surface of the base 51 to provide a reference for the subsequent installation of the main shaft 53. The main shaft 53 passes through the upper surface of the reference column 52, and a worm 54, a pressure sensor 55 and a wireless transmission block 56 are installed on the outer arc surface of the main shaft 53. The pressure sensor 55 is used to measure the pressure on the concrete pile 4, and then obtain the ultimate bearing capacity data; the wireless transmission block 56 is used to wirelessly transmit data to an external receiving device, and the flange 57 is fixedly installed on the surface of one side of the partition 22. One end of the transmission shaft 58 is movably connected to the flange 57, and the other end passes through the partition 22 and is installed with a worm gear 59 and a gear A510. Gear B511 is installed on one side of the enclosure 21 through the transmission shaft 58. The meshing connection between gear A510 and gear B511, and the worm gear 59 and the worm 54 is realized to realize the linkage between the displacement and pressure measurement of the concrete pile 4

[0045] As the concrete pile 4 continues to sink, the frictional resistance between the pile body and the surrounding soil, as well as the support resistance of the soil at the pile end, are gradually transmitted to the pressure sensor 55 through the cap sleeve 34 and the stress kit 33. The pressure sensor 55 uses a high-precision strain gauge sensor that can accurately sense pressure changes. When the pile body is subjected to soil resistance, the stress kit 33 undergoes a slight deformation, which drives the strain gauge resistance value of the pressure sensor 55 to change. The resistance change is converted into a voltage signal through a Wheatstone bridge circuit, and then after amplification and filtering, it is sent to the data processing terminal by the wireless transmission block 56 at a frequency of multiple times per second.

[0046] During the measurement process, the displacement of the concrete pile 4 is transmitted through the contact between the pile segment 41 and the worm gear 59. As the pile sinks, the teeth on the surface of the pile segment 41 engage with the worm gear 59, driving the worm gear 59 to rotate. The worm gear 54 then converts the rotational motion into axial displacement of the pressure sensor 55, further improving the measurement accuracy of the pressure sensor 55. At the same time, micro pressure cells are buried on the side and end of the pile to monitor the pile side resistance and pile end resistance in real time. When the pile reaches a depth of ten meters in the soil, the pressure sensor 55 displays the total pressure, and the pile side pressure cell provides feedback on the pile side resistance. By analyzing the changing trends of these data, such as the slowing growth of the pile side resistance between eight and ten meters in the soil and the continuous increase of the pile end resistance, changes in the bearing performance of the pile foundation can be determined, providing dynamic data support for determining the ultimate bearing capacity. When the reading of the pressure sensor 55 drops sharply under a certain load and the pile produces significant displacement, the load is determined to be the ultimate bearing capacity.

[0047] During the entire test process, the data collected by various sensors are transmitted in real time to a portable industrial computer equipped with professional data analysis software via a wireless transmission block (56) or a dedicated data line. The software interface can simultaneously display data curves such as the depth of burial, ultimate bearing capacity, friction resistance of the probe side wall, cone tip resistance, pile side resistance, and pile end resistance. First, the system automatically draws a curve of the relationship between the depth of burial and the ultimate bearing capacity, with the depth of burial as the horizontal axis and the ultimate bearing capacity as the vertical axis. A data point is recorded every ten centimeters to form a dynamic change curve.

[0048] Next, a multi-parameter coupling analysis model was established, combining the new static penetration test data with pile side and end resistance data. Using a finite element analysis algorithm, soil parameters (such as internal friction angle and cohesion) and pile parameters (such as pile diameter and length) were integrated with the sensor data. During the analysis, the changing trends of different data sequences were compared. For example, when the burial depth increased from 15 meters to 18 meters, the ultimate bearing capacity growth data and the sidewall friction resistance growth data were compared to determine whether a weak interlayer existed at that depth. If the pile side resistance increased slowly, the system automatically marked the data anomaly and prompted technicians to conduct on-site review. By repeatedly adjusting model parameters and verifying data, the new technology for determining the burial depth and ultimate bearing capacity of soil-squeezing piles was continuously optimized. Finally, a detailed test report was generated based on the data processing results. When slow growth in pile side resistance at a certain depth was found to affect the ultimate bearing capacity, the report would provide targeted construction technology recommendations, such as adjusting the pile driving speed or using pre-drilling to assist pile driving. This provides a scientific and accurate basis for pile foundation design and construction in actual projects.
