[0002] With the acceleration of urbanization, the construction industry has also developed rapidly, resulting in a surge in construction waste. As a type of construction waste, the treatment of construction waste has attracted considerable attention.

[0003] The screening and washing of construction waste to prepare recycled sand can effectively utilize construction waste, but this process incurs costs and environmental hazards. Therefore, the construction waste must be tested before screening and washing, and a comprehensive assessment of its economic and environmental benefits must be conducted based on the results. Among the many testing indicators for construction waste, sand content is a key indicator for the comprehensive assessment of economic and environmental benefits.

[0004] One existing method for detecting sand content involves slurrying the soil sample, allowing it to stand, and then visually observing the interface between sand and clay particles. However, because this method relies on visual inspection of the sand-clay particle interface, the process is difficult to quantify, thus compromising accuracy. Another method involves sampling, repeated washing, drying, and weighing. This method is cumbersome, requiring steps such as sieving and drying, is time-consuming, and the testing process is difficult to complete on-site, resulting in untimely results.

[0049] This application provides a CNC module, a method, apparatus, and equipment for detecting the sand content of engineering waste soil, which solves the technical problem that existing methods for detecting sand content are difficult to guarantee accuracy.

[0050] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0051] For easier understanding, please refer to Figure 1 , Figure 1 This is a flowchart of a method for detecting the sand content of engineering waste soil according to an embodiment of this application. Figure 1 As shown, the method for detecting the sand content of engineering waste soil in this embodiment specifically includes:

[0052] Step 101: Obtain the temperature of the mixed solution, wherein the mixed solution is prepared by mixing the engineering waste soil to be tested with water.

[0053] It should be noted that the method in this embodiment can be executed by a CNC module, and the temperature of the mixed solution can be measured by a temperature detection unit such as a temperature sensor. Therefore, after the temperature sensor measures the temperature of the mixed solution, it can send the temperature to the CNC module, which will then execute the detection step of determining the sand content of the engineering slag based on the temperature.

[0054] The mixed solution is prepared from the engineering waste soil to be tested and water. Therefore, in this step, the air-dried mass of the engineering waste soil should be weighed before the mixed solution is prepared, and the volume of the mixed solution should be compatible with the size of the container used to ensure the operability of subsequent turbidity measurement.

[0055] Step 102: Based on the temperature-detection location calculation formula, determine the turbidity detection location of the engineering waste soil in the mixed solution according to the temperature.

[0056] It should be noted that different particles settle at different rates in water. When engineering waste with different sand contents (the mass ratio of particles larger than 0.075 mm to all particles) is uniformly mixed in an aqueous solution, the settling rate varies significantly depending on particle size and solution temperature. Furthermore, the density of particles still suspended in the solution has a quantitative relationship with the turbidity of the solution. Therefore, in this embodiment, after obtaining the temperature of the mixed solution, the turbidity detection location of the engineering waste in the mixed solution is determined based on the temperature-detection location calculation formula. It is understood that the temperature value used to calculate the detection location should be the actual temperature measured after the mixed solution temperature has stabilized.

[0057] Step 103: When multiple turbidity values ​​measured at the turbidity detection location are obtained, the sand content of the engineering waste soil is determined based on the turbidity-sand content calculation formula.

[0058] It should be noted that after calculating and determining the turbidity detection location for the construction waste, the turbidity of the mixed solution can be detected at the corresponding location using a turbidity sensor or other turbidity detection unit. In this step, the construction waste needs to be evenly dispersed in the water by repeatedly inverting or stirring the mixed solution. Then, the mixed solution is allowed to stand, and the turbidity is measured when the predetermined standing time has elapsed.

[0059] The sand content detection method for engineering waste soil in this embodiment utilizes the principle that different particle sizes have different sedimentation rates. Starting from the turbidity change of the solution after engineering waste soil slurry formation, the turbidity detection location is calculated based on the solution temperature, and the sand content of the engineering waste soil is directly and quantitatively calculated from the turbidity detection results. Specifically, this embodiment detects the turbidity of the solution at a specific depth at a specific moment during the settling process of the mixed solution, thereby obtaining the sand content of the engineering waste soil. Compared to the method of visually observing the mud-sand boundary after settling, the accuracy is significantly improved. Compared to the testing method of repeated rinsing, drying, and weighing, this method greatly reduces testing steps, eliminates the limitations of the measurement environment, shortens the testing time, and significantly improves timeliness. It solves the technical problems of existing sand content detection methods that are difficult to guarantee accuracy and timeliness.

[0060] The above is a first embodiment of a method for detecting the sand content of engineering waste soil provided in this application. The following is a second embodiment of a method for detecting the sand content of engineering waste soil provided in this application.

[0061] Please see Figure 2 , Figure 2 This is a flowchart of another method for detecting the sand content of engineering waste soil according to an embodiment of this application, as shown below. Figure 2 As shown, the method for detecting the sand content of engineering waste soil in this embodiment specifically includes:

[0062] Step 201: Obtain the temperature of the mixed solution, wherein the mixed solution is prepared by mixing the engineering waste soil to be tested and water.

[0063] It should be noted that step 201 is described in the same way as step 101 in Embodiment 1. For details, please refer to the description of step 101 above, which will not be repeated here.

[0064] Step 202: Based on the temperature-detection location calculation formula, determine the turbidity detection location of the engineering waste soil in the mixed solution according to the temperature.

[0065] It should be noted that the temperature-detection location calculation formula in this step includes:

[0066] y = ax 2 +bx+c;

[0067] In the formula, y represents the turbidity detection location in mm, x represents the temperature in °C, and a, b, and c are constants, with a ranging from 0.015 to 0.03, b ranging from 2.5 to 5, and c ranging from 80 to 150. This formula is derived by fitting calculations based on Stoke's law, considering particle size and the average unit weight of common clay minerals.

[0068] Step 203: When multiple turbidity values ​​measured at the turbidity detection location are obtained, the sand content of the engineering waste soil is determined based on the turbidity-sand content calculation formula.

[0069] It should be noted that the turbidity-sand content calculation formula in this step includes:

[0070]

[0071] In the formula, η is the sand content; p is a constant, with a value ranging from 600 to 650; V is the volume of the mixed solution; T1 is the turbidity value measured after standing for t1 seconds, with a value ranging from 30 to 50; m is the air-dried mass of the engineering waste to be tested; and q is an adjustment coefficient. T2 is the turbidity value measured after standing for t2 seconds, with a value ranging from 120 to 200. T3 is the turbidity value measured after standing for t3 seconds, with a value ranging from 270 to 450. r, s, and e are all constants, with values ​​ranging from 5 to 8 for r, 4 to 7 for s, 0.8 to 1.5 for e, and 0.6 to 0.8 for n. This formula is based on the quantitative relationship between turbidity and particle specific surface area, and is adjusted using turbidity results from multiple measurements.

[0072] Step 204: Repeat steps 201 to 203 N times to obtain N+1 sand content rates, where N is a natural number.

[0073] It should be noted that, in order to ensure the accuracy of the calculation results, this embodiment measures the sand content multiple times and finally combines the sand content from multiple measurements to obtain the target sand content of the engineering waste soil.

[0074] Step 205: Combine N+1 sand content values ​​to obtain the optimized sand content of the engineering waste soil, and use the optimized sand content as the target sand content of the engineering waste soil.

[0075] It is understandable that, by combining N+1 sand content values, the optimal sand content of the engineering waste soil can be obtained by using the average of the N+1 sand content values ​​as the optimal sand content, or by using the median of the N+1 sand content values ​​as the optimal sand content. It should be noted that the above example is merely an illustrative example, and those skilled in the art can make corresponding settings as needed.

[0076] The sand content detection method for engineering waste soil in this embodiment utilizes the principle that different particle sizes have different sedimentation rates. Starting from the turbidity change of the solution after the engineering waste soil sample is slurried, the turbidity detection location is calculated by the temperature of the solution, and the sand content of the engineering waste soil is directly quantitatively calculated from the turbidity detection results. Compared with the method of visually observing the mud-sand boundary after standing, the accuracy is significantly improved. Compared with the test method of repeated rinsing, drying and weighing, the test steps are greatly reduced, the limitation of the measurement environment is eliminated, the test time is shortened, and the timeliness is significantly improved. It solves the technical problems of existing sand content detection methods that are difficult to guarantee detection accuracy and timeliness.

[0077] The above is a second embodiment of a method for detecting the sand content of engineering waste soil provided in this application. The following is an embodiment of a CNC module provided in this application.

[0081] The sand content calculation module 303 is configured to determine the sand content of the engineering waste soil based on the turbidity-sand content calculation formula when multiple turbidity values ​​measured at the turbidity detection location are obtained.

[0082] In one alternative implementation, the temperature-detection location calculation formula includes:

[0083] y = ax 2 +bx+c;

[0084] In the formula, y represents the detection location, x represents the temperature, and a, b, and c are all constants. The value of a ranges from 0.015 to 0.03, the value of b ranges from 2.5 to 5, and the value of c ranges from 80 to 150. In an exemplary embodiment, the turbidity-sand content calculation formula includes:

[0088] The polling module 304 is configured to repeatedly trigger the acquisition module 301, the location calculation module 302, and the sand content calculation module 303 N times to acquire N+1 sand content values, where N is a natural number.

[0089] The optimization module 305 is used to integrate N+1 sand content values ​​to obtain the optimized sand content of the engineering waste soil, and to use the optimized sand content as the target sand content of the engineering waste soil.

[0090] The CNC module in this embodiment utilizes the principle that different particle sizes have different sedimentation rates. Starting from the turbidity change of the solution after the engineering waste slurry is slurryed, it calculates the turbidity detection location by the temperature of the solution and directly calculates the sand content of the engineering waste slurry quantitatively from the turbidity detection results.
