Description

Technical Field

[0001] This invention relates to the field of resource recovery technology, and more specifically, to a method and apparatus for resource recovery of mud used in pile foundation construction. Background Technology

[0002] The mud used in pile foundation construction has a complex composition, containing solid particles such as clay, sand, and rock fragments, as well as chemical substances such as cement and admixtures. Vastly different geological conditions in different regions and varying construction techniques result in significant differences in mud composition—some are highly viscous, some have high sand content, some are strongly acidic or alkaline, and some have high heavy metal content. However, existing technologies mostly adopt a uniform approach for resource recovery and treatment. This "one-size-fits-all" method is difficult to accurately adapt to the complex and diverse characteristics of mud, often leading to low treatment efficiency, low resource utilization, and even potential secondary pollution. In the diverse composition of pile foundation construction sites, its limitations are becoming increasingly apparent, urgently requiring more targeted and adaptable treatment technologies to overcome these challenges. Summary of the Invention

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this invention, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] Example 1:

[0030] This embodiment provides a method for the resource-based treatment of mud slurry generated during pile foundation construction. It can be understood that this embodiment can lay out a scenario, such as: a scenario of resource-based treatment of a large amount of mud slurry generated at the pile foundation construction site.

[0031] See Figure 1 The figure shows that the method includes steps S1, S2, S3, S4 and S5.

[0032] Step S1: Obtain first information, which includes the signal collected after the ultrasonic wave passes through the mud tank to be tested;

[0033] In this step, signal excitation points and signal receiving points are set at both ends of the mud tank to be tested. Ultrasonic waves are emitted at the signal excitation points, and the signals collected by the ultrasonic waves are received at the signal receiving points, which is the first information.

[0034] Step S2: Based on the first information, detect whether there is a defect in the mud tank and obtain a judgment result. When the judgment result is that there is no defect in the mud tank, transport the mud tank to the resource utilization treatment site using a transport vehicle, and then obtain the second information. The second information includes the multimodal information corresponding to the pile foundation construction mud collected by the multimodal acquisition device.

[0035] In this step, the multimodal acquisition device includes infrared spectroscopy, laser-induced breakdown spectroscopy, dynamic image analysis camera, and ultrasonic sensor array. Infrared spectroscopy is used to acquire 1.0–2.5 μm spectral data; laser-induced breakdown spectroscopy is used to acquire 200–800 nm atomic emission spectra; dynamic image analysis camera is used to capture images of mud particles; and ultrasonic sensor array is used to acquire 0.1–10 MHz attenuation spectra.

[0036] Step S2 further includes steps S21, S22, S23, and S24, which specifically include:

[0037] Step S21: Obtain third information, which includes the signal collected after the ultrasonic wave passes through the defect-free mud tank;

[0038] Step S22: Convert the first information into a corresponding spectrogram to obtain a first spectrogram;

[0039] In this step, the first information can be processed using the Fast Fourier Transform to convert it into the corresponding spectrogram.

[0040] Step S23: Convert the third information into a corresponding spectrogram to obtain a second spectrogram;

[0041] Step S24: Perform defect detection on the mud tank based on the first spectrum diagram and the second spectrum diagram to obtain the judgment result.

[0042] In this step, the presence of defects in the mud tank can be determined based on the amplitudes of the first and second spectrum diagrams. If the amplitude of the first spectrum diagram is less than the amplitude of the second spectrum diagram, it can be determined that the mud tank has defects and cannot meet the mud transportation task. If the amplitude of the first spectrum diagram is not less than the amplitude of the second spectrum diagram, it can be determined that the mud tank has no defects and can perform the mud transportation task.

[0043] In this embodiment, the presence of defects in the mud tank is detected by the first information, thereby preventing mud leakage during transportation and avoiding resource waste, thus achieving the goal of ensuring transportation safety.

[0044] Step S3: Identify the composition of the pile foundation construction mud based on the second information to obtain the identification result;

[0045] Step S3 further includes steps S31, S32, S33, S34, and S35, which specifically include:

[0046] Step S31: Obtain the infrared spectral information, laser-induced breakdown spectral information, sand and gravel image information, and ultrasonic information included in the second information;

[0047] Step S32: Identify the clay based on the infrared spectral information to obtain a first identification result;

[0048] Step S32 further includes steps S321, S322, S323, S324, S325, and S326, which specifically include:

[0049] Step S321: Determine the water peak position information from the infrared spectral information;

[0050] Step S321 further includes steps S3211, S3212, and S3213, which specifically include:

[0051] Step S3211: Select a first wavelength range and a second wavelength range from the infrared spectral information;

[0052] In this step, the 1.45 μm water peak corresponds to the first overtone absorption of the OH bonds in water molecules, which is one of the most significant characteristic peaks of water in the near-infrared band and is sensitive to changes in water content. The 1.94 μm water peak is generated by the combination frequency absorption of the OH bonds in water molecules (i.e., the coupling of stretching and bending vibrations), and its intensity is linearly related to the water content, making it particularly suitable for quantitative analysis of samples with high water content. Therefore, the first wavelength range should cover 1.45 μm, and the second wavelength range should cover 1.94 μm. Furthermore, in the band below 1.3 μm, metal ions (such as Fe)... 3+ Cu 2+ The scattering / absorption of clay minerals (such as montmorillonite and kaolinite) and organic matter is strong, easily masking the water peak signal. Meanwhile, in the band greater than 2.1 μm, the hydroxyl groups (-OH) and carbonates (CO3) of clay minerals (such as montmorillonite and kaolinite) are also affected. 2 The absorption peaks are significant (e.g., the 2.2 μm clay hydroxyl peak), which may overlap with water peaks. Therefore, in this application, the first wavelength range selected includes the spectral band of 1.3–1.6 μm; the second wavelength range selected includes the spectral band of 1.8–2.1 μm. Selecting the 1.3–1.6 μm and 1.8–2.1 μm bands allows for precise localization of the 1.45 μm and 1.94 μm water peaks, corresponding to the first overtone and combination frequency absorption of water, respectively, and is sensitive to water content. This avoids interference from metal ions, organic matter, and clay hydroxyl groups, improving signal specificity and adapting to the sensitivity range of near-infrared instruments, ensuring data signal-to-noise ratio and stability, thereby improving the accuracy of mud component identification.

[0053] Step S3212: Use the sliding window method to coarsely locate the water peak in the first wavelength range and the second wavelength range to obtain coarse location information;

[0054] Step S3213: Calculate the second derivative of the spectral signal using the second derivative method in the coarse positioning information to obtain the water peak position information.

[0055] In this step, the second derivative method, by calculating the second derivative of the spectral signal, can more sensitively capture the changing trend of the spectral curve, and a clear extreme point will appear at the water peak, thus accurately calibrating the position of the water peak.

[0056] In this implementation, the water peak in the infrared spectrum may not be a sharp, single peak, but rather exhibit variations in width and shape. The sliding window method can preliminarily determine the approximate location of the water peak within a specific wavelength range, but this location may contain some error. Therefore, the second derivative method is needed to further and more precisely determine the center position of the water peak, improving the accuracy of the location.

[0057] Step S322: Extract peak height based on the water peak position information to obtain water content characteristic information;

[0058] Step S323: Obtain the moisture feature matrix, which includes standard moisture feature information under different moisture contents;

[0059] Step S324: Calculate the matching degree between the moisture characteristic information and each moisture content spectrum in the moisture characteristic matrix, and determine the weighting coefficients;

[0060] In this step, the least squares method is used to fit and calculate the matching degree between the moisture feature information and each moisture content spectrum in the moisture feature matrix. The weight coefficient that minimizes the difference between the moisture feature information and the weight coefficient × moisture feature matrix is ​​selected as the optimal weight coefficient, thereby separating the specific contribution of the moisture signal.

[0061] Step S325: Compensate the infrared spectrum according to the weighting coefficients to obtain the compensated infrared spectral information;

[0062] In this step, the specific calculation process for the compensated infrared spectral information is as follows:

[0063] S1=S2-α·M

[0064] In the above formula, S1 represents the compensated infrared spectral information, S2 represents the original infrared spectral information collected in real time, α represents the optimal weighting coefficient, and M represents the moisture feature matrix.

[0065] Step S326: Identify the clay based on the compensated infrared spectral information.

[0066] In this step, the compensated infrared spectral information is sent to the convolutional neural network to output the clay content.

[0067] Step S33: Identify heavy metals based on the laser-induced breakdown spectrum information to obtain a second identification result;

[0068] In this step, a dual-pulse laser excitation combined with internal standard normalization is used to reduce the clay matrix effect and effectively improve the heavy metal identification results. Specifically, the first pulse is applied to the surface of the preheated mud, removing loose surface particles or adsorbed water through ablation, forming micro-pits (micrometer-scale) and exposing the fresh internal matrix. The second pulse is focused on the fresh sample within the pits, generating high-temperature plasma. Fe is selected as the internal standard element and added to the mud, ensuring uniform distribution. The sample with the added internal standard element and the emission spectrum signal of the internal standard element in the plasma are obtained. The emission spectral intensities of the analyte and the Fe internal standard element are measured, and the intensity of the Fe internal standard element is used to normalize the intensities of other elements. Since the content of the Fe internal standard element in the mud is known and stable, its emission spectral intensity is less affected by the clay matrix effect. By calculating the ratio of the intensity of the analyte element to the intensity of the Fe internal standard element, the influence of the clay matrix effect on the analyte signal can be eliminated or reduced, thus obtaining more accurate element content information. After being normalized by internal standards, the elemental content data can more accurately reflect the actual content of each element in the sample, effectively reducing the errors and interference caused by the clay matrix effect and improving the accuracy of heavy metal identification.

[0069] It should be noted that the laser-induced breakdown spectrum identifies the element types using a random forest classifier, and the electrochemical sensor distinguishes the ions corresponding to the redox peaks using a support vector machine, thus outputting a list of heavy metal types and ion types, achieving heavy metal identification.

[0070] Step S34: Identify the sand and gravel based on the sand and gravel image information and the ultrasonic information to obtain a third identification result;

[0071] In this step, the particle size distribution of the sand and gravel image information is statistically analyzed after segmentation by U-Net, and the particle size and distribution of the sand and gravel can be obtained by regularizing the particle size accumulation curve through ultrasonic inversion. It should be noted that the segmentation of image information using U-Net and the processing of ultrasonic information using regularization inversion are technical solutions well known to those skilled in the art, and therefore will not be described in detail here.

[0072] Step S35: Construct a component classification report based on the first identification result, the second identification result, and the third identification result to obtain the identification result.

[0073] In this step, the composition classification report includes the clay content, sand and gravel particle size distribution, and heavy metal types.

[0074] In this embodiment, multimodal information fusion is used to achieve accurate identification of mud components. Infrared spectroscopy is used to specifically identify characteristic functional groups of clay, laser-induced breakdown spectroscopy is used to quantitatively analyze heavy metal elements, and visual features of sand and gravel images and particle distribution data from ultrasound are combined to construct a multi-dimensional component classification report. This method combines qualitative analysis and quantitative detection, and can efficiently distinguish between clay, heavy metals, and sand and gravel, providing accurate basis for subsequent separation and resource recovery, and improving the comprehensiveness, accuracy, and efficiency of mud component identification.

[0075] Step S4: Based on the identification results, the pile foundation construction mud is separated to obtain the separation results, which include sand, clay and heavy metal enriched phases;

[0076] Step S4 further includes steps S41, S42, S43, and S44, which specifically include:

[0077] Step S41: Obtain the preset constraints;

[0078] In this step, the preset constraints include, but are not limited to, a hydrocyclone pressure range of 0.2-0.8 MPa; a magnetic separator force range of 0.5-1.2 T; and a flotation reagent dosage range of 0.1-0.3 L / m³. 3 The sand and gravel recovery rate is greater than or equal to 95%.

[0079] Step S42: Establish a multi-objective optimization model based on the preset constraints. The optimization model is used to output hydrocyclone pressure parameters, magnetic separator force, and flotation agent dosage.

[0080] In this step, the objective function is defined as follows:

[0081] Maximize sand and gravel recovery rate: f1 = ∑(sand and gravel separated amount / total amount of sand and gravel);

[0082] Minimize flotation reagent dosage: f2 = ∑(SDS dosage);

[0083] The SDS mentioned above indicates that sodium dodecyl sulfate is selected as the flotation agent.

[0084] Step S43: Send the recognition result to the multi-objective optimization model for solving, and obtain the solution result;

[0085] In this step, the multi-objective optimization model is solved using a multi-objective genetic algorithm. It is understood that this application selects the NSGA-II algorithm for solving the problem.

[0086] Step S44: Debug the equipment according to the solution results to obtain the separation results.

[0087] In this step, the solution obtained based on the NSGA-II algorithm includes hydrocyclone pressure parameters, magnetic separator force, and flotation reagent dosage.

[0088] Step S44 further includes steps S441, S442, S443, S444, S445, and S446, which specifically include:

[0089] Step S441: Obtain a first control command based on the solution result. The first control command is used to control the hydrocyclone to operate with the output hydrocyclone pressure parameters.

[0090] It is understandable that by adjusting the pressure of the hydrocyclone, the rotation speed and centrifugal force of the mud inside the hydrocyclone can be controlled, thereby achieving the separation of sand and gravel in the mud.

[0091] Step S442: Obtain the first separation result according to the first control command;

[0092] Step S443: After obtaining the first separation result, obtain the second control command, which is used to add flotation agent to the first separation result;

[0093] In this step, the physicochemical properties of the mineral surface are altered by adding flotation agents, allowing the target mineral to selectively adhere to air bubbles, thereby achieving separation from other minerals. Sodium dodecyl sulfate is added as a flotation agent in sand and gravel separation. It can selectively adsorb onto the surface of certain specific minerals, making them hydrophobic. When air is introduced to form air bubbles, these mineral particles will adhere to the air bubbles and float to the surface with the air bubbles, where they will be scraped off as concentrate. Meanwhile, other minerals that are not affected by the flotation agent remain in the slurry, achieving the effect of separating and enriching the target mineral.

[0094] Step S444: Obtain the second separation result according to the second control command;

[0095] Step S445: After obtaining the second separation result, obtain the third control command. The third control command is used to control the magnetic separator to work with the output magnetic separator strength.

[0096] In this step, by adjusting the magnetic separator's field strength, the iron-containing sand and gravel are attracted by the magnetic field and adsorbed onto the surface of the magnetic separator's cylinder. As the cylinder rotates, they are carried to a designated location and discharged, thus achieving separation from other non-magnetic sand and gravel.

[0097] Step S446: Obtain the separation result according to the third control command.

[0098] In this embodiment, the separation sequence is: first, separation using a hydrocyclone; then, flotation; and finally, magnetic separation. Flotation utilizes the differences in the physicochemical properties of mineral surfaces, and by adding a flotation agent, the target mineral adheres to the air bubbles to achieve separation. Performing flotation first allows for the preferential separation of heavy metal minerals whose surface properties can be effectively altered by the flotation agent and which have good adhesion to the air bubbles, without being affected by the magnetic separation process. If magnetic separation is performed first, some non-magnetic but highly floatable heavy metal minerals may be mixed with other minerals during the magnetic separation process, affecting the separation effect of these minerals in subsequent flotation. Meanwhile, magnetic separation is mainly for magnetic minerals such as those containing iron. If magnetic separation is performed first, the magnetic separation process may have a mechanical effect on the particles in the mud, such as changing the agglomeration or dispersion state of the particles. This may affect the contact and interaction between the flotation agent and the mineral particles in subsequent flotation, resulting in poor flotation effect. The separation sequence of this invention allows each step to play its full role, thereby achieving a better overall separation effect. If the sequence is changed, it may disrupt the continuity of this process, requiring the entire process parameter to be re-optimized and adjusted, increasing the complexity and uncertainty of the process.

[0099] Step S5: Based on the separation results, the pile foundation construction mud is subjected to resource recovery treatment.

[0100] In this step, the separation results include sand, clay, and heavy metal-enriched phases. The separated sand can be reused as aggregate raw materials in construction projects, replacing traditional natural sand or artificially crushed aggregates, thus achieving resource recycling. Clay requires further dehydration before it can be utilized as a resource. Direct disposal of the heavy metal-enriched phase may pollute the environment; it needs to be stabilized to convert the heavy metals into a chemically stable, low-migration form to reduce environmental risks. The resource-based treatment of the heavy metal-enriched phase includes: 1. First, screening for sulfate-reducing bacteria resistant to heavy metals and mixing them with modified bentonite to prepare a microbial-mineral composite carrier. The composite carrier is added to the slurry in a certain proportion. Utilizing the adsorption properties of modified bentonite, the sulfate-reducing bacteria are directionally enriched around the heavy metal ions. The sulfate-reducing bacteria metabolize and produce S... 21. The slurry, after undergoing microbial-mineral synergistic stabilization treatment, is mixed with aluminosilicate materials (such as steel slag and fly ash) according to the formula ratio. The mixture is then crushed into particles of appropriate size to prepare for subsequent sintering. This process further disperses the material components evenly, ensuring that heavy metal ions can better react with the aluminosilicate materials and enter the crystal lattice structure during subsequent sintering. 2. The pretreated material is fed into a sintering furnace and sintered under controlled oxygen conditions at 1200℃. Sintering is divided into an oxidation section and a reduction section. In the oxidation section, organic matter and other impurities are removed. In the reduction section, the N2-CO2 mixed atmosphere in the furnace is precisely controlled to ensure that heavy metal ions react fully with the aluminosilicate materials and enter the glassy phase lattice to form a stable crystal structure. After sintering, the material undergoes post-treatment processes such as cooling to obtain a bulk density ≤800kg / m³. 3 The lightweight, high-strength ceramsite meets all green building material standards, achieving heavy metal stabilization and resource conversion.

[0101] Step S5 further includes steps S51, S52, S53, and S54, which specifically include:

[0102] Step S51: Obtain the dielectric constant of the clay in the separation results;

[0103] In this step, the dielectric constant of the mud is obtained by a dielectric constant sensor to characterize its microwave absorption capacity.

[0104] Step S52: Calculate the optimal microwave frequency based on the dielectric constant;

[0105] In this step, the calculation process for the optimal microwave frequency is as follows:

[0106]

[0107] In the above formula, ε represents the dielectric constant, μ represents the magnetic permeability, and f represents the optimal microwave frequency. Step S53: Obtain the preset electric field parameters.

[0108] In this step, the preset electric field parameter gradient range includes 10-30V / cm. In a specific implementation, the electric field strength is 10V / cm in the low-frequency region and increases to 25V / cm in the high-frequency region.

[0109] Step S54: Dehydrate the clay in a coordinated manner according to the optimal microwave frequency and the preset electric field parameters to obtain dehydrated clay.

[0110] In this step, a coupled electric-thermal-flow model is built using multiphysics simulation software to connect the electric, thermal, and flow fields, simulating the dewatering process and predicting the slurry dewatering rate and temperature distribution. If the local temperature of the slurry exceeds 80°C, the microwave power is immediately reduced by 10% per second using PID control, similar to lowering the temperature of an air conditioner; if the current density exceeds 80mA / cm², the microwave power is also reduced. 2 This slows down the rate of increase in electric field strength. Ultimately, the dehydration parameters were optimized. In one specific implementation, the electric field strength changed from 12V / cm to 22V / cm, and the microwave power in the low-frequency region was 1.8kW / m. 3 4.2kW / m in the high-frequency range 3 Compared to conventional mud dewatering methods, which are energy-intensive and inefficient, this invention employs a gradient electric field-microwave synergistic dewatering technology with significant advantages. It sets initial parameters through precise analysis of mud characteristics, monitors and dynamically adjusts the electric and microwave parameters in real time during dewatering, and uses a multi-physics coupling model to accurately predict the dewatering process, greatly improving the efficiency and economy of mud dewatering.

[0111] This invention first identifies the composition of the pile foundation construction mud, then separates the mud based on the identification results, and performs targeted resource recovery treatment on the separated mud components. For example, the clay is dehydrated using gradient electric field-microwave synergistic dehydration technology, and the heavy metal-enriched phase is stabilized by microorganism-mineral synergistic stabilization and high-temperature sintering to prepare lightweight, high-strength ceramsite that meets green building material standards. This achieves resource recycling, reduces the limitations of unified treatment, lowers environmental risks, and helps achieve the goals of resource recovery and environmental protection of construction waste. It is suitable for pile foundation construction sites with varying compositions.

[0112] Example 2:

[0113] like Figure 2 As shown, this embodiment provides a device for the resource utilization and treatment of pile foundation construction mud. The device includes an acquisition module 901, a first processing module 902, a second processing module 903, a third processing module 904, and a fourth processing module 905, specifically including:

[0114] The acquisition module 901 is used to acquire first information, the first information including the signal collected after the ultrasonic wave passes through the mud tank to be tested;

[0115] The first processing module 902 is used to detect whether there is a defect in the mud tank based on the first information and obtain a judgment result. When the judgment result is that there is no defect in the mud tank, the mud tank is transported to the resource utilization treatment site by a transport vehicle and then the second information is obtained.
