Description

Technical Field

[0001] This invention relates to the field of geotechnical engineering foundation testing, specifically to a method for correcting the inclination and acoustic parameters of acoustic logging tubes. Background Technology

[0002] Pile foundations are the most widely used type of foundation in China, and their engineering quality directly affects the safety of the superstructure. my country uses over ten million piles annually, with a large number of construction companies of varying technical capabilities. Therefore, the construction and quality inspection of pile foundations have always been a major concern.

[0003] Acoustic wave transmission method, as a non-destructive testing method for the integrity of foundation piles, is used to determine the location, extent and degree of defects in the pile body. It has the characteristics of simple operation and fast speed, and is widely used in practical engineering testing.

[0004] In the acoustic wave testing of foundation piles, the sound velocity of each acoustic probe is not a direct measurement, but is calculated based on the actual propagation time of the sound wave in the concrete of each acoustic probe measured by the instrument and the span between the top of each acoustic probe tube. When the acoustic probe tubes maintain good parallelism, the calculated results will not deviate significantly from the actual results and will not affect the inspection results.

[0005] However, in actual engineering, it is impossible to keep the sonic logging pipes perfectly parallel. If the installation is not done properly or there are problems when connecting or fixing the sonic logging pipes, the sonic logging pipes will be seriously tilted, bent or warped. This will cause a large difference between the actual movement distance and span of each sonic logging line in the same section, resulting in a large difference between the calculated sonic logging line velocity and the actual sonic logging line velocity, making it impossible to analyze the measured data.

[0006] To analyze the measured data, the calculated sound velocity of the acoustic logging line needs to be corrected. Existing correction methods for acoustic logging tubes correct by fitting the distance between two acoustic logging tubes. This method has the following problems:

[0007] (1) The variation law of the sound speed-depth curve is complex, and it is difficult to directly fit and correct the entire curve. Instead, the curve inflection point is used as the dividing point, and manual segment fitting is performed. In this process, it is easily affected by human error.

[0008] (2) When there are gradual defects in the pile body or the entire section of the sonic logging pipe is tilted, the overall trend of the sound velocity-depth curve will be affected. Traditional methods often treat the overall deviation of the sound velocity-depth curve as the pipe tilt phenomenon of the sonic logging pipe, and then correct and fit it, making it difficult for traditional methods to detect the gradual defects in the pile body.

[0009] (3) This method cannot determine the bending direction, bending depth and specific bending conditions of the sonic logging pipe, and cannot provide relevant data for studying the pipe inclination of the sonic logging pipe. Summary of the Invention

[0010] The purpose of this invention is to address the problems existing in the prior art by providing a method for correcting the tilt and acoustic parameters of a sonic logging tube.

[0011] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0012] A method for correcting the tilt and acoustic parameters of a sonic logging tube includes the following steps:

[0013] S1: Install a measurement module on the acoustic transceiver transceiver. The acoustic transceiver transceiver transceiver is used to measure acoustic parameters, including acoustic time, amplitude, frequency, and waveform. The measurement module is used to measure its own position parameters, including tilt angle α and azimuth angle β.

[0014] S2: Cut the sonic logging pipes extending from the top of the cast-in-place pile to the same elevation, measure the span between the tops of each sonic logging pipe, and select any point on the same plane where the tops of each sonic logging pipe are located as the reference point O. The reference point O is used as the origin of the two-dimensional coordinate system. The coordinates of the tops of each sonic logging pipe in the two-dimensional coordinate system are determined by measurement.

[0015] S3: Place the acoustic transceiver transducers at the bottom of different acoustic logging tubes, and then lift the acoustic transceiver transducers upwards synchronously. Several detection points are arranged along the acoustic logging tube from bottom to top, and the distance between adjacent detection points is e. When the acoustic transceiver transducer and the measurement module pass through the detection point, they send the measured acoustic parameters and position parameters to the receiving host, until the acoustic transceiver transducer is removed from the acoustic logging tube.

[0016] S4: Let the distance between the top of the acoustic tube and the measurement module in the two-dimensional coordinate system be S, S = tanα × e. The receiving host determines the coordinates of the measurement module in the two-dimensional coordinate system when it passes any of the detection points through β and S, and then calculates the distance L between the measurement modules on each acoustic transceiver based on the two-dimensional coordinate system.

[0017] S5: The receiving host calculates the sound velocity based on the span and the sound time measured at each of the detection points to draw the original depth curve of sound velocity and amplitude. Then, the L measured by the measurement module at different detection points is used to replace the span to obtain the corrected depth curve of sound velocity and amplitude. The original depth curve and the corrected depth curve are compared.

[0018] This invention eliminates the need for manual fitting; the receiving host automatically replaces and corrects numerical values ​​after receiving the measurement data, thus reducing the impact of human error on the experimental results.

[0019] The present invention uses the data from the measurement module and the acoustic transceiver to calculate the spacing L of each of the acoustic transceiver at any depth, and uses the spacing L instead of the span to participate in the drawing of the depth curve, which has a smaller error compared with manual fitting.

[0020] The present invention can obtain the two-dimensional coordinates of the acoustic logging tube at any depth according to the measurement module, thereby enabling the understanding of the bending direction, bending depth and specific bending conditions of the acoustic logging tube.

[0021] This invention can identify whether there are gradual defects in the pile body, avoiding misjudging the gradual defects in the pile body as pipe tilting of the sonic logging pipe. Even if there are gradual defects in the pile body and the sonic logging pipe is tilted at the same time, the method provided by this invention can also eliminate the influence of the pipe tilt and detect the gradual defects in the pile body.

[0022] Preferably, the top ends of each of the acoustic tubes are connected sequentially in a clockwise or counterclockwise direction to form a closed figure on a horizontal plane, and the reference point O is located within the closed figure.

[0023] Where on-site conditions permit, the reference point O should be located at the center between each of the sonic logging tubes to facilitate the establishment of the coordinate system and the measurement of the span.

[0024] Preferably, the specific steps of step S2 are as follows: taking due north as the direction of the Y-axis of the two-dimensional coordinate system and due east as the direction of the X-axis of the two-dimensional coordinate system, firstly, measure the distance between the top of each sonic logging pipe and the reference point O; secondly, measure the angle formed by the top of adjacent sonic logging pipes and the reference point O; and finally, calculate the coordinates of each sonic logging pipe top in the two-dimensional coordinate system based on the measured distance and angle.

[0025] Preferably, the drawing steps of step S5 are as follows: first, the cast-in-place pile is divided into several sections, and then the original depth curve and the corrected depth curve are drawn for each section according to the measured data.

[0026] Preferably, based on the depth of the detection point and the coordinates measured by the measurement module at the detection point, the actual position of the acoustic logging tube to which the detection point belongs at the depth of the detection point is determined, thereby determining the specific depth of the bending point of the acoustic logging tube.

[0027] Preferably, the method for comparing the original depth curve and the corrected depth curve in step S5 is as follows:

[0028] S5.1: When the sound velocity curve on the original depth curve changes as a whole, if the sound velocity curve on the corrected depth curve does not change as a whole, it is determined that the acoustic tube is tilted.

[0029] S5.2: When the sound velocity curve and amplitude curve of the modified depth curve also change drastically at the same depth, it is determined that the pile body of the cast-in-place pile has a defect at that depth.

[0030] Preferably, the azimuth angle β is used to record the offset angle between the measurement module and the due north direction.

[0031] Preferably, the acoustic transceiver is connected to the receiving host via a cable, and the acoustic transceiver is raised by pulling the cable.

[0032] Preferably, the measurement module is a JY901 module, an attitude sensor, or a small inertial navigation chip.

[0033] The JY901 module, attitude sensor, or small inertial navigation chip can all measure the attitude angle of the object being measured and output it in Euler angles or quaternion mode.

[0034] Preferably, the detection points at the bottom of each of the acoustic tubes are at the same depth to ensure that the calculated spacing L is more accurate.

[0035] Compared with the prior art, the beneficial effects of the present invention are:

[0036] (1) This invention does not require manual fitting. After the measurement data is obtained by the receiving host, the numerical values ​​are automatically replaced and corrected, which reduces the impact of human error on the experimental results.

[0037] (2) The present invention uses the data of the measurement module and the acoustic transceiver transducer to calculate the spacing L of each acoustic transceiver transducer at any depth, and uses the spacing L to replace the span to participate in the drawing of the depth curve, which has a smaller error compared with manual fitting.

[0038] (3) The present invention can obtain the two-dimensional coordinates of the acoustic tube at any depth according to the measurement module, thereby understanding the bending direction, the depth of bending and the specific bending situation of the acoustic tube.

[0039] (4) The present invention can identify whether there is a gradual defect in the pile body, and avoid misjudging the gradual defect in the pile body as the pipe tilt of the sonic logging pipe. Even if there is a gradual defect in the pile body and the sonic logging pipe tilts at the same time, the method provided by the present invention can also eliminate the influence of the pipe tilt of the sonic logging pipe and discover the gradual defect in the pile body.

[0064] 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 merely some embodiments of the present invention, and not all embodiments. 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.

[0065] In the description of this invention, it should be noted that the terms "middle", "upper", "lower", "left", "right", "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.

[0066] like Figures 1-23 As shown, the specific scheme of the embodiment is as follows: Before conducting acoustic wave testing of the foundation pile, the arrangement of the acoustic logging tubes 2 needs to be determined according to the pile diameter of the pile 1 to be tested. When the pile diameter is less than or equal to 1500mm, three acoustic logging tubes 2 are buried in an equilateral triangle arrangement; when the pile diameter is greater than 1500mm, four acoustic logging tubes 2 are buried in a square arrangement; during acoustic wave testing, an acoustic transceiver transducer is placed in each acoustic logging tube 2.

[0067] When four sonic logging tubes 2 are embedded in the cast-in-place pile 1, assuming the four sonic logging tubes 2 are pipe A, pipe B, pipe C, and pipe D respectively, a method for correcting the inclination and acoustic parameters of the sonic logging tubes 2 includes the following steps:

[0068] S1: Install a measurement module on the acoustic transceiver transceiver. The acoustic transceiver transceiver transceiver is used to measure acoustic parameters, including acoustic time, amplitude, frequency and waveform. The measurement module is used to measure its own position parameters, including tilt angle α and azimuth angle β. The azimuth angle β is used to record the offset angle between the measurement module and the due north direction.

[0069] S2.1: Cut the sonic logging pipe 2 out of the top of the cast-in-place pile 1 to the same elevation, and measure the span between the tops of each sonic logging pipe 2;

[0070] S2.2: Connect the top ends of each sonic logging tube 2 in a clockwise or counterclockwise direction to form a closed figure on the horizontal plane. The reference point O is located inside the closed figure. Where the environment and regulations of the construction site permit, the reference point O should be set at the center of the closed figure as much as possible to facilitate the establishment of the coordinate system and the measurement of the span.

[0071] S2.3: The reference point O is used as the origin of the two-dimensional coordinate system. The direction of the Y-axis of the two-dimensional coordinate system is due north, and the direction of the X-axis of the two-dimensional coordinate system is due east. Let the top ends of the four sonic logging tubes 2 be A0, B0, C0 and D0 in the two-dimensional coordinate system. First, measure the distances between A0-O, B0-O, C0-O and D0-O. Then measure the values ​​of ∠AOB, ∠BOC, ∠COD and ∠DOA. Finally, calculate the coordinates of A0, B0, C0 and D0 in the two-dimensional coordinate system based on the measured distances and angles.

[0072] S3: Place the acoustic transceiver transducers at the bottom of different acoustic logging tubes 2, and then lift the acoustic transceiver transducers upwards synchronously. Several detection points are set along the acoustic logging tube 2 from bottom to top, with a spacing of e between adjacent detection points. When the acoustic transceiver transducer and the measurement module pass through the detection point, they send the measured acoustic parameters and position parameters to the receiving host until the acoustic transceiver transducer is removed from the acoustic logging tube 2.

[0073] S4.1: Let the distance between the top of the acoustic tube 2 and the measurement module in the two-dimensional coordinate system be S, where S = tanα × e. The receiving host determines the coordinates of the measurement module in the two-dimensional coordinate system when it passes through any detection point through β and S. The coordinates of the measurement module located in tube A in the two-dimensional coordinate system are A'0, the coordinates of the measurement module located in tube B in the two-dimensional coordinate system are B'0, the coordinates of the measurement module located in tube C in the two-dimensional coordinate system are C'0, and the coordinates of the measurement module located in tube D in the two-dimensional coordinate system are D'0.

[0074] S4.2: According to the Pythagorean theorem, the distance L between the measurement modules on each acoustic transceiver is calculated using a two-dimensional coordinate system. When the acoustic transceiver in tube A and the acoustic transceiver in tube B are a group used for transmission and reception, the distance L is the distance between A'0 and B'0. When the acoustic transceiver in tube C and the acoustic transceiver in tube D are a group used for transmission and reception, the distance L is the distance between C'0 and D'0. The rest can be deduced in the same way.

[0075] S4.3: Based on the depth of the detection point and the coordinates measured by the measurement module at the detection point, determine the actual position of the acoustic tube 2 at the depth of the detection point, thereby determining the specific depth at which the acoustic tube 2 bends.

[0076] S5.1: First, the cast-in-place pile 1 is divided into several sections. The receiving host calculates the sound velocity based on the span and the sound time measured at each detection point. Then, based on the measured data and the calculated sound velocity, the original depth curve is drawn for each section.

[0077] S5.2: Replace the span with L measured at different detection points using the measurement module to obtain the corrected depth curves of sound velocity and wave amplitude;

[0078] S5.3: Compare the original depth curve and the corrected depth curve. If the sound velocity curve 3 on the original depth curve shifts as a whole, but the sound velocity curve 3 on the corrected depth curve does not shift as a whole, it is determined that the sonic logging tube 2 has a pipe tilt phenomenon. If the sound velocity curve 3 and the amplitude curve 4 on the corrected depth curve also change drastically at the same depth, it is determined that the pile body of the cast-in-place pile 1 has a defect at that depth.

[0079] Before placing the acoustic transceiver into the acoustic tube 2, the acoustic transceiver is suspended at the top of the acoustic tube 2 to calibrate the position parameters of the measurement module. After the acoustic transceiver is removed from the acoustic tube 2, the coordinates of the measurement module in the two-dimensional coordinate system when the acoustic transceiver is located at each detection point are calculated from top to bottom based on all the obtained position parameters.

[0080] like Figure 5 As shown, after obtaining the coordinates of A'0, B'0, C'0 and D'0 at different depths, a three-dimensional coordinate system is established with the reference point O as the origin. The A'0, B'0, C'0 and D'0 at different depths are connected by software to obtain the actual shape of each sonic logging tube 2 in the cast-in-place pile 1.

[0081] Both the original depth curve and the corrected depth curve include the sound velocity curve 3 and the amplitude curve 4. The vertical axis of the original depth curve and the corrected depth curve is in meters, and the horizontal axis of the original depth curve and the corrected depth curve includes dB and km / s.

[0082] The acoustic transceiver is connected to the receiving host via a cable, and the acoustic transceiver is raised by pulling the cable.

[0083] The measurement module uses the JY901 module, attitude sensor or small inertial navigation chip.

[0084] The detection points at the bottom of each acoustic tube 2 are at the same depth. When the bottom of each acoustic tube 2 is not blocked, the bottom of each acoustic tube 2 is at the same depth. When the bottom of any acoustic tube 2 is blocked, the depth of the detection points at the bottom of each acoustic tube 2 needs to be manually reset to ensure that the acoustic transceiver can rise synchronously from the same depth, thereby avoiding a significant impact on the measurement of the spacing L.

[0085] In practical application, taking a model cast-in-place pile 1 with a pile diameter greater than 1500mm and a pile length of 10m as an example, some of the sonic logging tubes 2 are tilted. The model cast-in-place pile 1 has a defect of about 30cm at around 8m. The distance e between adjacent detection points is set to 100mm. When drawing the depth curve, the pile body is divided into six sections.

[0086] like Figures 6-11 As shown, in the six original depth curves without correction, the sound velocity curves 3 of sections 1-2, 1-3, 2-3, 2-4 and 3-4 all show an overall shift at depths greater than 5m.

[0087] If it is corrected manually using traditional methods, it will be like... Figures 12-17 As shown, the span of the offset segment of the sound velocity curve 3 was manually modified to approximate a curve with a depth of less than 5m.

[0088] However, after this method is modified, such as Figures 18-23 As shown, the corrected sound velocity curves 3 do not show the obvious overall shift seen in the original depth curve diagram. It can be assumed that the sonic logging tubes 2 associated with sections 1-2, 1-3, 2-3, 2-4 and 3-4 all exhibit tube skewing.

[0089] like Figure 6 As shown, in the original depth curve diagram, the sound velocity curve 3 and amplitude curve 4 of profile 1-2 near a depth of 2m undergo simultaneous drastic changes. After correction using this method, as shown... Figure 18 As shown, the sound velocity curve 3 and amplitude curve 4 of section 1-2 still change drastically at a depth of 2m, which confirms that the model cast-in-place pile 1 has obvious defects at a depth of 2m.

[0090] like Figure 7 and 11 As shown, in the original depth curves, both profiles 1-3 and 3-4 exhibit slight fluctuations in amplitude curve 4 near a depth of 8m. However, after traditional manual correction... Figure 13 and 17 In the original text, it was not apparent that the sound velocity curve 3 and amplitude curve 4 near that depth underwent a simultaneous and dramatic change. However, after correction using this method, as shown in the original text... Figure 19 and 23 As shown, the sound velocity curve 3 and amplitude curve 4 of sections 1-3 and 3-4 changed drastically at a depth of 8m, which confirms that the model cast-in-place pile 1 has obvious defects at a depth of 8m.

[0091] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
