Description

Technical Field

[0001] This application relates to the field of concrete pouring technology, and in particular to a method for detecting the embedment depth of a conduit in concrete. Background Technology

[0002] When constructing an underground anti-seepage wall, it is necessary to excavate wall trenches to a predetermined depth at a predetermined location in advance, fill them with wall-protecting grout, then lower the guide pipe vertically to near the bottom of the trench, and then pour concrete into the trench through the guide pipe.

[0003] According to the process requirements, the end of the guide pipe needs to be continuously embedded in the concrete poured into the trench. If the end of the guide pipe is pulled out of the concrete, it can easily cause a break in the wall formed by the pouring. However, if the guide pipe is embedded too deeply in the concrete, it will be impossible to remove. Therefore, during the concrete pouring process, the guide pipe needs to be dynamically pulled out to ensure that the end of the guide pipe is within a reasonable embedment depth range.

[0004] In existing technologies, a sensor is installed on the conduit, and the depth of the conduit embedded in concrete is determined based on the signal collected by the sensor. However, if this sensor malfunctions, it will cause abnormal signal acquisition, directly leading to an incorrect judgment of the conduit's embedment depth in the concrete. Therefore, relying solely on a single signal from a single sensor to detect the conduit's embedment depth in concrete has low reliability. Summary of the Invention

Furthermore, by comprehensively calculating the target embedment depth using the embedment depth information determined by both the pressure and vibration sensors, the accuracy of embedment depth detection is improved, ensuring that the conduit remains within a preset depth range in the concrete. This allows for continuous concrete pouring through the conduit, preventing discontinuities in the resulting wall and improving wall quality.

Detailed Implementation

[0052] The terms "first," "second," and "third," etc., used in this application specification and accompanying drawings are used to distinguish different objects, not to limit a specific order.

[0053] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0054] To ensure clarity and conciseness in the description of the following embodiments, a brief introduction to the related technologies is given first:

[0055] When constructing an underground anti-seepage wall, it is necessary to excavate wall trenches to a predetermined depth at a predetermined location in advance, fill them with wall-protecting grout, then lower the guide pipe vertically to near the bottom of the trench, and then pour concrete into the trench through the guide pipe.

[0056] According to the process requirements, the end of the guide pipe needs to remain embedded in the concrete poured in the trench until the anti-seepage wall section is completed, at which point the guide pipe can be pulled out of the concrete. If the end of the guide pipe is pulled out of the concrete during the pouring process, it can easily cause a break in the formed wall. However, if the guide pipe is embedded too deeply in the concrete, it may become impossible to remove. Therefore, during the concrete pouring process, the guide pipe needs to be dynamically pulled out to ensure that the end of the guide pipe remains within a reasonable embedment depth.

[0057] For example, the embedment depth of the duct in the concrete during the pouring process can be specified as 1.5 meters to 6 meters.

[0058] In existing technologies, a sensor is installed on the conduit, and the depth of the conduit embedded in the concrete is determined based on the signal collected by the sensor. However, if the sensor malfunctions, it will cause abnormal signal acquisition, directly leading to an incorrect judgment of the conduit's embedment depth in the concrete. Therefore, relying on a single signal collected by a single sensor to detect the embedment depth of the conduit in concrete has low reliability.

[0059] In view of this, this application provides a method for detecting the embedment depth of a conduit in concrete. This method can be executed by a processing device, such as a programmable logic controller (PLC) or a detection instrument. The method compares the spatial position of the conduit detected by a pressure sensor with that detected by a vibration sensor to determine if either sensor is malfunctioning, avoiding misjudgment based on a single signal and improving detection reliability. By comprehensively calculating the embedment depth information determined by both the pressure and vibration sensors, the target embedment depth is improved, enhancing the accuracy of embedment depth detection and ensuring that the conduit remains within a preset depth range in the concrete. This allows for continuous concrete pouring through the conduit, preventing discontinuities in the formed wall and improving wall quality. It also prevents the conduit from being too deeply embedded to be easily removed, ensuring smooth extraction during concrete pouring and effectively improving the quality of the concrete pouring.

[0060] The following describes the application scenarios of this method, such as... Figure 1As shown, in this application scenario, the conduit 1 is equipped with a first pressure sensor 2, a second pressure sensor 3, a first vibration sensor 4, a second vibration sensor 5, a temperature sensor 6, and an ultrasonic sensor 7. The first pressure sensor 2 and the second pressure sensor 3 are distributed along the axial direction of the conduit 1. The first vibration sensor 4 is located on one side of the first pressure sensor 2, the second vibration sensor 5 is located on one side of the second pressure sensor 3, and the temperature sensor 6 and the ultrasonic sensor 7 are located between the first pressure sensor 2 and the second pressure sensor 3.

[0061] The first pressure sensor and the first vibration sensor can be installed 1.5 meters from the bottom of the conduit, and the second pressure sensor and the second vibration sensor can be installed 6 meters from the bottom of the conduit.

[0062] Specifically, such as Figure 3-4 As shown, the conduit 1 is provided with multiple mounting parts 11. The mounting parts 11 are connected to the outer wall of the conduit 1 through support ribs 12, and the mounting parts 11 have installation spaces. The first pressure sensor 2, the second pressure sensor 3, the first vibration sensor 4, the second vibration sensor 5, the temperature sensor 6, and the ultrasonic sensor 7 are respectively installed in the installation spaces of the corresponding mounting parts 11.

[0063] like Figure 4-5 As shown, the conduit 1 is also equipped with multiple cable sheaths 13, each with a cable groove. The first pressure sensor 2, the second pressure sensor 3, the first vibration sensor 4, the second vibration sensor 5, the temperature sensor 6, and the ultrasonic sensor 7 are connected to the processing equipment via signal lines 14. The signal lines 14 of each sensor are installed in the corresponding cable grooves of their respective cable sheaths 13. During the pouring of concrete 200 through the conduit 1, the signal lines 14 are protected from damage by the concrete 200 because they are installed in the cable grooves of the cable sheaths 13, ensuring the accuracy of the sensor data.

[0064] After the trench is excavated, a wall-protecting slurry 100 is filled into the trench to prevent the trench wall from collapsing. Then, a conduit 1 equipped with multiple sensors is lowered into the trench. Concrete 200 is poured into the trench through the conduit 1, and the concrete 200 fills the lower layer of the wall-protecting slurry 100.

[0065] As concrete 200 is continuously poured, the embedment depth of guide pipe 1 in concrete 200 will increase, requiring guide pipe 1 to be pulled out and the embedment depth of guide pipe 1 in concrete 200 to be dynamically adjusted.

[0066] The following is combined Figure 1The application scenario shown illustrates a method for detecting the embedment depth of a conduit 1 in concrete 200, provided by an embodiment of this application. The method for detecting the embedment depth of the conduit 1 in concrete 200 provided by this embodiment of the application is as follows: Figure 2 As shown, it includes the following steps:

[0067] S101. The processing device obtains the medium density of the space between the first pressure sensor 2 and the second pressure sensor 3 on the conduit 1, and determines the first spatial position type between the first pressure sensor 2 and the second pressure sensor 3 on the conduit 1 based on the medium density, the density of the wall slurry 100 and the density of the concrete 200.

[0068] Specifically, the method by which the processing device obtains the medium density of the space between the first pressure sensor 2 and the second pressure sensor 3 on the conduit 1 includes: obtaining the initial medium density of the space between the first pressure sensor 2 and the second pressure sensor 3 on the conduit 1; correcting the initial medium density to obtain the medium density of the space between the first pressure sensor 2 and the second pressure sensor 3 on the conduit 1.

[0069] In this embodiment, the medium density of the space between the first pressure sensor 2 and the second pressure sensor 3 on the conduit 1 is obtained by correcting the initial medium density, which improves the accuracy and anti-interference ability of the medium density calculation, reduces the medium density error, and helps to improve the accuracy of burial depth detection.

[0070] The initial medium density of the space between the first pressure sensor 2 and the second pressure sensor 3 on the conduit 1 can be calculated using the following formula:

[0071]

[0072] in, Indicates the initial medium density. This indicates the pressure of the medium at the location detected by the first pressure sensor 2. This indicates the pressure of the medium at the location detected by the second pressure sensor 3. Represents gravitational acceleration. This indicates the distance between the first pressure sensor 2 and the second pressure sensor 3.

[0073] For example Figure 1As shown, the first pressure sensor 2 is located in the wall-protecting slurry 100, and the second pressure sensor 3 is located in the concrete 200. The first pressure sensor 2 collects the first pressure signal generated by the wall-protecting slurry 100 at the corresponding position and transmits the first pressure signal to the processing device. The second pressure sensor 3 collects the second pressure signal generated by the concrete 200 at the corresponding position and transmits the second pressure signal to the processing device. The processing device calculates the initial medium density of the space between the first pressure sensor 2 and the second pressure sensor 3 on the conduit 1 when the conduit 1 is at the current position based on the first pressure and the second pressure.

[0074] In one specific embodiment, the initial medium density is corrected, and the medium density of the space between the first pressure sensor 2 and the second pressure sensor 3 on the conduit 1 can be calculated using the following formula:

[0075]

[0076] in, Indicates the density of the medium. Indicates the initial medium density. Indicates the temperature effect coefficient. This indicates the temperature corresponding to the location detected by temperature sensor 6. This indicates the reference temperature corresponding to the location of temperature sensor 6.

[0077] Temperature influence coefficient This can be determined experimentally. For example, by collecting multiple sets of data and using data analysis methods such as linear regression, a curve showing the relationship between density and temperature can be fitted. The slope of the curve is the temperature influence coefficient. Reference temperature It can be determined through experiments, for example, by selecting a temperature value with reference significance as the reference temperature in the experiment.

[0078] During operation, temperature sensor 6 collects the temperature signal at its location and transmits the temperature signal to the processing device; the processing device calculates the medium density of the space between the first pressure sensor 2 and the second pressure sensor 3 on the conduit 1 based on the temperature value and the initial medium density.

[0079] In this embodiment, the initial medium density is corrected by detecting the temperature of the space between the first pressure sensor 2 and the second pressure sensor 3 on the conduit 1. This reduces the interference of temperature on the pressure sensor detection results, improves the accuracy of the medium pressure detected by the pressure sensor, and thus improves the detection accuracy of the medium density.

[0080] In another specific embodiment, the initial medium density is corrected, and the medium density of the space between the first pressure sensor 2 and the second pressure sensor 3 on the conduit 1 can be calculated using the following formula:

[0081]

[0082] in, Indicates the density of the medium. Indicates the initial medium density. Indicates the sound speed-density conversion factor. This indicates the sound velocity of the medium at the location detected by ultrasonic sensor 7. This indicates the reference sound velocity of the medium at the location of the ultrasonic sensor 7.

[0083] Sound speed to density conversion factor This can be determined experimentally. For example, by collecting multiple sets of data and using data analysis methods such as linear regression, a curve showing the relationship between density and sound speed can be fitted. The slope of the curve is the sound speed-density conversion coefficient. Reference temperature It can be determined through experiments, for example, by selecting a temperature value with reference significance as the reference temperature in the experiment.

[0084] During operation, the ultrasonic sensor 7 collects the sound velocity signal at its location and transmits the sound velocity signal to the processing device; the processing device calculates the medium density of the space between the first pressure sensor 2 and the second pressure sensor 3 on the conduit 1 based on the sound velocity and the initial medium density.

[0085] In this embodiment, the initial medium density is corrected by detecting the sound velocity of the medium in the space between the first pressure sensor 2 and the second pressure sensor 3 on the conduit 1. This reduces the interference of the sound velocity on the pressure sensor detection results, improves the accuracy of the medium pressure detected by the pressure sensor, and thus improves the detection accuracy of the medium density.

[0086] In another specific embodiment, the initial medium density is corrected, and the medium density of the space between the first pressure sensor 2 and the second pressure sensor 3 on the conduit 1 can be calculated using the following formula:

[0087]

[0088] in, Indicates the density of the medium. Indicates the initial medium density. Indicates the frequency influence coefficient. This indicates that the frequency of the first pressure fluctuation is obtained by performing a spectrum analysis on the first pressure signal collected by the first pressure sensor 2. This indicates that the frequency of the second pressure fluctuation is obtained by performing a spectrum analysis on the second pressure signal collected by the second pressure sensor 3. This indicates the reference frequency for pressure fluctuations.

[0089] Frequency influence coefficient This can be determined experimentally. For example, by collecting multiple sets of data and using data analysis methods such as linear regression, a curve showing the relationship between density and the frequency of pressure fluctuations can be fitted. The slope of the curve is the frequency influence coefficient c. (Pressure fluctuation reference frequency) By analyzing the mechanism of pressure fluctuations theoretically and combining relevant engineering experience or existing research results, the pressure fluctuation frequency value under standard operating conditions can be selected as the reference frequency for pressure fluctuations.

[0090] In this embodiment, the initial medium density is corrected based on the pressure fluctuation frequency of the pressure sensor, which reduces the interference of the pressure fluctuation frequency on the detection results of the pressure sensor, improves the accuracy of the medium pressure detected by the pressure sensor, and thus improves the detection accuracy of the medium density.

[0091] In one specific embodiment, the dielectric density is... The wall protection slurry has a density of 100. The density of concrete 200 is The portion of the conduit 1 located between the first pressure sensor 2 and the second pressure sensor 3 is the embedded part 15.

[0092] Based on the density of the medium, the density of the wall-protecting slurry 100, and the density of the concrete 200, the type of the first spatial position between the first pressure sensor 2 and the second pressure sensor 3 on the conduit 1 can be determined in the following way:

[0093] like = The first spatial position type between the first pressure sensor 2 and the second pressure sensor 3 on the conduit 1 is that the embedded part 15 is located in the wall-protecting slurry 100; if < Then, the first spatial position type between the first pressure sensor 2 and the second pressure sensor 3 on the conduit 1 is that one end of the embedded part 15 is located in the wall grout 100, and the other end of the embedded part 15 is located in the concrete 200; if = The first spatial position type between the first pressure sensor 2 and the second pressure sensor 3 on the conduit 1 is that the embedded part 15 is located in the concrete 200.

[0094] S102. The processing device obtains the first medium type corresponding to the position of the first vibration sensor 4 and the second medium type corresponding to the position of the second vibration sensor 5, and determines the second spatial position type between the first vibration sensor 4 and the second vibration sensor 5 on the conduit 1 based on the first medium type and the second medium type.

[0095] Specifically, the first medium type corresponding to the location of the first vibration sensor 4 and the second medium type corresponding to the location of the second vibration sensor 5 can be obtained in the following ways: obtain the first vibration frequency of the medium at the location of the first vibration sensor 4; if the first vibration frequency is within a first preset range, the first medium type is wall-protecting slurry 100; if the first vibration frequency is within a second preset range, the first medium type is concrete 200; obtain the second vibration frequency of the medium at the location of the second vibration sensor 5; if the first vibration frequency is within a first preset range, the second medium type is wall-protecting slurry 100; if the second vibration frequency is within a second preset range, the second medium type is concrete 200.

[0096] The first vibration frequency of the medium at the location of the first vibration sensor 4 can be obtained by the following formula:

[0097]

[0098] in, Indicates the first vibration frequency. Indicates frequency index, Indicates the sampling period. Indicates the number of sampling points. k Indicates the first k One sampling point, This indicates the location of the medium measured by the first vibration sensor 4. k Acceleration values ​​at each sampling point Represents the natural constant. It represents the imaginary unit.

[0099] The second vibration frequency of the medium at the location acquired by the second vibration sensor 5 can be obtained by the following formula:

[0100]

[0101] in, Indicates the first vibration frequency. Indicates frequency index, Indicates the sampling period. Indicates the number of sampling points. k Indicates the first k One sampling point, This indicates the location of the medium measured by the second vibration sensor 5. k Acceleration values ​​at each sampling point Represents the natural constant. It represents the imaginary unit.

[0102] Frequency Index The target frequency is set; the sampling period is set. This indicates the set sampling interval.

[0103] Vibration sensors collect acceleration signals of medium vibration, perform Fourier transform on the acceleration signals, and convert the time-domain signals to the frequency domain for analysis, realizing the conversion from the collected acceleration time-domain signals to spectral characteristics, thereby calculating the vibration frequency.

[0104] The first preset range is the vibration frequency range corresponding to the wall-protecting slurry 100. The reference value of the vibration frequency of the wall-protecting slurry 100 is determined by experiment. Set the allowable error range The first preset range is .

[0105] The second preset range is the vibration frequency range corresponding to concrete 200. The reference value of the vibration frequency of concrete 200 is determined by test. Set the allowable error range The second preset range is .

[0106] In one specific embodiment, the portion of the conduit 1 located between the first vibration sensor 4 and the second vibration sensor 5 is the embedded part 15. The method for determining the second spatial position type between the first vibration sensor 4 and the second vibration sensor 5 on the conduit 1 according to the first medium type and the second medium type includes: if both the first medium type and the second medium type are wall-protecting slurry 100, then the second spatial position type between the first vibration sensor 4 and the second vibration sensor 5 on the conduit 1 is that the embedded part 15 is located in the wall-protecting slurry 100; if the first medium type is wall-protecting slurry 100 and the first medium type is concrete 200, then the second spatial position type between the first vibration sensor 4 and the second vibration sensor 5 on the conduit 1 is that one end of the embedded part 15 is located in the wall-protecting slurry 100 and the other end of the embedded part 15 is located in the concrete 200; if both the first medium type and the second medium type are concrete 200, then the second spatial position type between the first vibration sensor 4 and the second vibration sensor 5 on the conduit 1 is that the embedded part 15 is located in the concrete 200.

[0107] S103. The processing device compares the first spatial location type and the second spatial location type. If the first spatial location type and the second spatial location type are consistent, the first burial depth information is determined based on the medium density between the first pressure sensor 2 and the second pressure sensor 3. The second burial depth information is determined based on the vibration signal collected by the first vibration sensor 4 and the vibration signal collected by the second vibration sensor 5. The target burial depth information is determined based on the first burial depth information and the second burial depth information.

[0108] For example Figure 1 As shown, the first pressure sensor 2 and the first vibration sensor 4 are located in the wall grout 100, and the second pressure sensor 3 and the second vibration sensor 5 are located in the concrete 200. If the first spatial position type obtained from the pressure sensor is that one end of the embedded part 15 is located in the concrete 200 and the other end is located in the wall grout 100, and the second spatial position type obtained from the vibration sensor is also that one end of the embedded part 15 is located in the concrete 200 and the other end is located in the wall grout 100, then the first spatial position type and the second spatial position type are consistent. If the first spatial position type is that the embedded part 15 is entirely located in the concrete 200, and the second spatial position type is that one end of the embedded part 15 is located in the concrete 200 and the other end is located in the wall grout 100, then the first spatial position type and the second spatial position type are inconsistent.

[0109] If the first spatial location type and the second spatial location type are inconsistent, it indicates that at least one of the pressure sensor and the vibration sensor is faulty, the burial depth information is unavailable, and the pressure sensor and the vibration sensor need to be repaired.

[0110] The embedment depth information is the embedment depth of guide tube 1 in concrete 200.

[0111] The method for determining the first burial depth information based on the medium density between the first pressure sensor 2 and the second pressure sensor 3 can be as follows: pre-configure the mapping relationship between the medium density and the burial depth of the conduit 1 in the concrete 200, find the burial depth of the conduit 1 in the concrete 200 corresponding to the medium density according to the mapping relationship, and obtain the first burial depth information.

[0112] The second burial depth information can be determined by pre-configuring a mapping relationship between vibration frequency and the burial depth of the guide pipe 1 in the concrete 200, finding the first burial depth of the guide pipe 1 in the concrete 200 corresponding to the first vibration frequency according to the mapping relationship, finding the second burial depth of the guide pipe 1 in the concrete 200 corresponding to the second vibration frequency according to the mapping relationship, calculating the average value of the first burial depth and the second burial depth, and obtaining the second burial depth information.

[0113] The target burial depth information can be determined by calculating the average of the first and second burial depth information.

[0114] The method for detecting the embedment depth of the conduit 1 in concrete 200 provided in this application compares the spatial position of the conduit 1 detected by the pressure sensor with the spatial position detected by the vibration sensor to determine whether the pressure sensor and vibration sensor are abnormal, avoiding misjudgment from a single signal and improving detection reliability. The method calculates the target embedment depth by combining the embedment depth information determined by the pressure sensor and vibration sensor, which improves the embedment depth detection accuracy, making the embedment depth detection accuracy reach ±0.8cm or even higher. This ensures that the conduit 1 is always within the preset depth range in the concrete, which not only enables continuous concrete pouring through the conduit 1, preventing discontinuities in the poured wall and improving the quality of the wall, but also prevents the conduit 1 from being buried too deep and unable to be removed, ensuring that the conduit 1 can be smoothly pulled out during the concrete pouring process, which can effectively improve the quality of concrete pouring.

[0115] In one specific embodiment, such as Figure 6 As shown, the processing equipment is installed in the power distribution cabinet 8, which is equipped with a touch screen 9, a yellow indicator light 113, a red indicator light 111, and a green indicator light 112. The power distribution cabinet 8 is connected to the power supply and can provide power to the processing equipment, the touch screen 9, the yellow indicator light 113, the red indicator light 111, and the green indicator light 112.

[0116] Users can operate the touch screen 9 to input relevant information, and can also obtain information such as the burial depth of the conduit 1 through the touch screen 9.

[0117] Yellow indicator light 113, red indicator light 111, and green indicator light 112 are used to indicate different operating conditions:

[0118] When the target burial depth information is less than the first threshold, the red indicator light 111 lights up, indicating that the embedded part 15 of the conduit 1 is in the wall slurry 100.

[0119] When the target burial depth information is greater than the first threshold and less than the second threshold, the red indicator light 111 goes out and the green indicator light 112 lights up, indicating that one end of the embedded part 15 of the conduit 1 is in the wall grout 100 and the other end is in the concrete 200.

[0120] When the target burial depth information is greater than the second threshold, the green indicator light 112 goes out and the red indicator light 111 lights up, indicating that the embedded part 15 of the guide pipe 1 is completely in the concrete 200, and the pipe should be pulled out in time.

[0121] During the removal of catheter 1, when the target burial depth information is less than the first threshold, the red indicator light 111 goes out and the green indicator light 112 lights up, indicating that the embedded part 15 of catheter 1 is in the wall slurry 100, and the removal of the catheter should be stopped.

[0122] When any sensor signal is lost, the yellow indicator light 113 will illuminate to indicate a fault.
