[0021] The technical solutions in the embodiments of the present application will be apparently and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0022] Referring to Figure 1 The first aspect of the present application provides a quality control method of a concrete precast beam, comprising: step one, obtaining environment parameters belonging to a concrete precast beam expected manufacturing process, analyzing environment compliance factors of the concrete precast beam expected manufacturing process, and matching a concrete precast beam manufacturing process compliance parameter set according to the environment compliance factors of the concrete precast beam expected manufacturing process.

[0023] In a specific embodiment, the present application can deeply analyze and accurately obtain the environment compliance factors of the concrete precast beam expected manufacturing process by comprehensively obtaining the environment parameters belonging to the concrete precast beam expected manufacturing process, which lays a solid scientific basis for the subsequent manufacturing process and ensures that the manufacturing process can closely match the current manufacturing environment, thereby enhancing the manufacturing stability and durability of the concrete precast beam and further improving the quality of the concrete precast beam.

[0024] Specifically, the matching of the concrete precast beam manufacturing process compliance parameter set is specifically matched as follows: the environment compliance factors of the concrete precast beam expected manufacturing process are matched with the concrete precast beam manufacturing process compliance parameter set corresponding to each environment compliance factor interval stored in the control database, so as to obtain the concrete precast beam manufacturing process compliance parameter set corresponding to the environment compliance factors of the concrete precast beam expected manufacturing process. In an example embodiment, it is assumed that the environment compliance factors of a certain concrete precast beam expected manufacturing process belong to a certain environment compliance factor interval stored in the control database, wherein the concrete precast beam manufacturing process compliance parameter set corresponding to the certain environment compliance factor interval includes: a concrete reference water-cement ratio of 0.6, a reference average prestress of a sample detection position region 1 of 3000 Newton, a reference average prestress of a sample detection position region 2 of 4500 Newton, a reference average prestress of a sample detection position region 3 of 3550 Newton, a concrete strength grade of 5, etc. Then, the concrete precast beam manufacturing process compliance parameter set corresponding to the environment compliance factors of the concrete precast beam expected manufacturing process includes: a concrete reference water-cement ratio of 0.6, a reference average prestress of a sample detection position region 1 of 3000 Newton, a reference average prestress of a sample detection position region 2 of 4500 Newton, a reference average prestress of a sample detection position region 3 of 3550 Newton, a concrete strength grade of 5, etc.

[0025] Specifically, the environmental compliance factor of the concrete precast beam expected manufacturing process is analyzed in detail as follows:

[0026]

[0027] In the formula, ECF represents the environmental compliance factor of the concrete precast beam expected manufacturing process, PWR represents the average pH value of the environment to which the concrete precast beam expected manufacturing process belongs in the environmental monitoring period, APD represents the average temperature of the environment to which the concrete precast beam expected manufacturing process belongs in the environmental monitoring period, CHG d represents the average concentration of the dth harmful gas in the environment to which the concrete precast beam expected manufacturing process belongs in the environmental monitoring period, ΔPWR represents the preset average pH value reference value in the control database, ΔAPD represents the preset average temperature reference value in the control database, F represents the environmental compliance ratio factor corresponding to the unit value of the average concentration of the harmful gas preset in the control database, e is a natural constant, d is the number of various harmful gases, d = {1, 2, 3,..., s}, and s is the total number of harmful gas types.

[0028] It should be explained that the environmental parameters in the environmental monitoring period have an important influence on the product quality and compliance in the expected manufacturing process of the concrete precast beam. Specifically, the average pH value of the water used reflects the basic chemical properties of the manufacturing environment. If the average pH value of the water used deviates significantly from the average pH value reference value of the water used, the balance of various chemical components in the concrete will be destroyed during the concrete mixing process, causing abnormal chemical reactions inside the concrete, thereby affecting its physical and chemical properties. This not only significantly slows down the solidification process of the concrete, making it difficult to achieve the expected strength, but also seriously weakens its durability, making the concrete more susceptible to erosion and damage during long-term use. At the same time, the average temperature is directly related to the solidification rate and strength development of the concrete material, and the average temperature affects the solubility of harmful gases in water. If the average temperature deviates significantly from the average temperature reference value, more harmful gases will dissolve into the water used, thereby exacerbating the deviation of the pH value of the water used. In addition, the average concentration of harmful gases as a key indicator may also affect the internal structure of the concrete precast beam through penetration or chemical reactions. Therefore, the above parameters together constitute the environmental background of the concrete precast beam manufacturing process, thereby negatively affecting the production quality and environmental compliance of the concrete precast beam.

[0029] The above-mentioned average pH value reference value of the water used represents the reference value of the average pH value of the water used in the environment to which the concrete precast beam expected manufacturing process belongs in the environmental monitoring period. The above-mentioned average temperature reference value represents the reference value of the average temperature of the environment to which the concrete precast beam expected manufacturing process belongs in the environmental monitoring period.

[0030] The environmental compliance ratio factor corresponding to the unit value of the average concentration of the harmful gas indicates a value of the influence degree of the unit value of the average concentration of the harmful gas on the environmental compliance factor of the expected manufacturing process of the precast concrete beam. The control database stores the corresponding relationship of the ratio factor. For example, the average concentration of the harmful gas can be input into the control database. The control database automatically matches the environmental compliance ratio factor corresponding to the unit value of the average concentration of the harmful gas according to the preset corresponding relationship of the ratio factor.

[0031] In the example embodiment, the change table of the environmental compliance factor of the expected manufacturing process of the precast concrete beam and the corresponding parameter thereof is shown in Table 1.

[0032] Table 1 Change table of environmental compliance factor of expected manufacturing process of precast concrete beam and corresponding parameter thereof

[0033]

[0034] In the example embodiment, the average water pH reference value is set to be pH 7.2, the average temperature reference value is set to be 27 degrees Celsius, and the value of the environmental compliance ratio factor corresponding to the unit value of the average concentration of the harmful gas is set to be 0.95. As can be seen from Table 1, when the average water pH significantly deviates from the average water pH reference value (for example, pH 5.3 significantly deviates from pH 7.2 in Table 1), it indicates that more harmful gas is dissolved in the water, and the average concentration of various harmful gases is at a high level, such as 0.002 mol / L, 0.003 mol / L, and 0.009 mol / L, respectively. At this time, the temperature accelerates the dissolution of the harmful gas in the water, and the average temperature also significantly deviates from the average temperature reference value (for example, 35 degrees Celsius significantly deviates from 27 degrees Celsius in Table 1). The comprehensive effect on the environmental compliance degree makes the environmental compliance degree low, which is specifically manifested as the environmental compliance factor at a low level, which is 81%.

[0035] Further, the analysis of the environmental compliance factor of the concrete precast beam expected manufacturing process is as follows: the environmental parameters of the concrete precast beam expected manufacturing process include the average pH of the water used in the environment monitoring period of the environment where the concrete precast beam expected manufacturing process belongs, the average temperature of the environment where the concrete precast beam expected manufacturing process belongs in the environment monitoring period, and the average concentration of various harmful gases in the environment where the concrete precast beam expected manufacturing process belongs in the environment monitoring period; the above-mentioned environment monitoring period refers to the time period for monitoring the environment where the concrete precast beam manufacturing belongs, and the specific duration is determined by the project analysis engineer; the above-mentioned average pH of the water used in the environment monitoring period of the environment where the concrete precast beam expected manufacturing process belongs refers to the average value obtained by testing the pH of the water used in the environment monitoring period of the environment where the concrete precast beam expected manufacturing process belongs, and the pH is an index for measuring the acidity or alkalinity of a solution. In the manufacturing process of the concrete precast beam, the pH of the water used may affect the performance of the concrete material, such as the hydration reaction rate of cement, the setting time of concrete, and the strength development, etc. The pH of the water used in each sample collected in the environment monitoring period can be measured by a pH meter and processed by averaging, and the result is marked as the average pH of the water used in the environment monitoring period of the environment where the concrete precast beam expected manufacturing process belongs; the above-mentioned average temperature of the environment where the concrete precast beam expected manufacturing process belongs in the environment monitoring period refers to the average value obtained by continuously monitoring the temperature of the environment in the environment monitoring period of the environment where the concrete precast beam expected manufacturing process belongs. The real-time temperature detected by each temperature sensor installed in the environment of the concrete precast beam manufacturing can be integrated and processed by averaging, and the result is the average temperature of the environment where the concrete precast beam expected manufacturing process belongs in the environment monitoring period; the above-mentioned average concentration of various harmful gases in the environment where the concrete precast beam expected manufacturing process belongs in the environment monitoring period refers to the average concentration value obtained by continuously sampling and analyzing various harmful gases in the environment in the environment monitoring period of the environment where the concrete precast beam expected manufacturing process belongs. The environment gas in the environment monitoring period can be sampled and collected to obtain each sample environment gas, and the gas concentration contained in each sample environment gas can be tested by a gas detector. The same harmful gas concentration is processed by averaging to obtain the average concentration of each harmful gas, wherein the harmful gas refers to the gas that has a corrosive effect on the concrete precast beam, and specifically includes sulfur dioxide, hydrogen chloride, hydrogen sulfide, and nitrogen oxides, etc.

[0036] The average pH value of the environment in which the concrete precast beam manufacturing process is expected to take place during the environmental monitoring period, the average temperature of the environment in which the concrete precast beam manufacturing process is expected to take place during the environmental monitoring period, and the average concentration of various harmful gases in the environment in which the concrete precast beam manufacturing process is expected to take place during the environmental monitoring period are analyzed comprehensively to obtain an environmental compliance factor of the concrete precast beam manufacturing process, wherein the environmental compliance factor of the concrete precast beam manufacturing process refers to a numerical value of the environmental compliance degree of the concrete precast beam manufacturing process.

[0037] Step two, collect the expected manufacturing process parameters of the concrete precast beam, and combine the compliance parameter set of the concrete precast beam manufacturing process to evaluate the expected manufacturing quality compliance index of the concrete precast beam, and compare it with the expected manufacturing quality compliance threshold.

[0038] The expected manufacturing quality compliance threshold represents the minimum value of the reasonable range of the expected manufacturing quality compliance index of the concrete precast beam, which is extracted from the control database.

[0039] Specifically, the evaluation of the expected manufacturing quality compliance index of the concrete precast beam includes the following specific evaluation process:

[0040] The expected manufacturing process parameters of the concrete precast beam include the concrete water-cement ratio of the concrete precast beam, the vibration amplitude curve of the concrete precast beam, and the prestress of each sample detection position point in the sample detection position area of the concrete precast beam. The concrete water-cement ratio of the concrete precast beam refers to the ratio of the mass of water to the mass of cement in the concrete, which is an important parameter in the design of concrete mix proportion and directly affects the strength, durability and workability of the concrete. It can be extracted from the construction planning scheme.

[0041] The vibration amplitude of each detection point is located and extracted from the vibration amplitude curve of the precast concrete beam. The standard deviation of the vibration amplitude at each detection point is processed, and the processing result is marked as the vibration amplitude dispersion value of the precast concrete beam. The vibration amplitude dispersion value of the precast concrete beam refers to the numerical value of the dispersion of the vibration amplitude experienced by the precast concrete beam during the vibration process. The vibration amplitude curve of the precast concrete beam refers to the graphical representation of the change of vibration amplitude with monitoring time points obtained by monitoring the vibration stage during the manufacturing process of the precast concrete beam. The expected manufacturing process of the precast concrete beam is simulated using Building Information Modeling (BIM) technology. By integrating information from the design, construction, and operation and maintenance stages in the construction planning scheme, a digital three-dimensional model is constructed, which accurately reflects the structure, dimensions, materials, and manufacturing process of the precast concrete beam. Based on this, the BIM software can... The simulation covers the entire manufacturing process of precast concrete beams, from raw material preparation, formwork installation, and rebar tying to concrete pouring, vibration, and curing. In the vibration simulation, Building Information Modeling (BIM) technology utilizes dynamic simulation algorithms to dynamically simulate the vibration behavior of the vibrator inside or on the surface of the concrete, based on preset vibration parameters (such as the type, power, frequency, and vibration time of the vibrator) and the specific shape, size, and material properties of the precast concrete beam. As the simulation progresses, the BIM software records and calculates the amplitude of the vibrator at different locations and detection times in real time. The vibration amplitudes at different locations are averaged to obtain the vibration amplitude at different detection times. The BIM software then denoises the vibration amplitudes at different detection times and connects them to form a complete vibration amplitude curve, which is the vibration amplitude curve of the precast concrete beam. In one example embodiment, the vibration amplitude curve of the precast concrete beam is as follows: Figure 3 As shown, the relationship between vibration amplitude and monitoring time points is illustrated. The horizontal axis represents the detection time point in minutes, and the vertical axis represents the vibration amplitude in centimeters. The vibration amplitude at each detection location point 1 is processed by standard deviation, and the processing result is marked as the discrete value of vibration amplitude of precast concrete beam. The detection location points are randomly arranged on the vibration amplitude curve.

[0042] It needs to be explained that Building Information Modeling (BIM) technology is a design and management tool based on digital modeling. By integrating various relevant information of a building project (such as data from the design, construction, and operation and maintenance stages) and combining them into a three-dimensional model, it enables comprehensive management and optimization of the building project. This model not only includes the physical characteristics and spatial relationships of the building, but also non-geometric information such as the building's functions and performance.

[0043] The prestress of each sample detection position point of each sample detection position area of the concrete precast beam is processed by averaging, and the processing result is marked as the average prestress of each sample detection position area of the concrete precast beam. The prestress of each sample detection position point of each sample detection position area of the concrete precast beam refers to the measured prestress value at different sample detection position points of the concrete precast beam. Prestress is a pressure applied to the structure during construction to improve the performance of the structure during use. For the concrete precast beam, prestress can improve its carrying capacity, delay the time of crack occurrence, and increase the durability of the component. It can be extracted from the construction planning scheme. Each sample detection position area and each sample detection position point are determined by manufacturing planning engineers according to the design drawings, technical requirements, quality standards, size, shape and material properties of the concrete precast beam.

[0044] The concrete reference water-cement ratio and the reference average prestress of each sample detection position area are extracted from the concrete precast beam manufacturing process compliance parameter set. The concrete reference water-cement ratio represents the reference value of the concrete water-cement ratio of the concrete precast beam. The reference average prestress of each sample detection position area represents the reference value corresponding to the average prestress of each sample detection position area of the concrete precast beam.

[0045] The environmental compliance factor of the expected manufacturing process of the concrete precast beam, the concrete water-cement ratio of the concrete precast beam, the vibration amplitude dispersion value of the concrete precast beam, the average prestress of each sample detection position area of the concrete precast beam, the concrete reference water-cement ratio and the reference average prestress of each sample detection position area are combined to obtain the expected manufacturing quality compliance index of the concrete precast beam. In this embodiment, the expected manufacturing quality compliance index of the concrete precast beam represents the numerical value of the expected manufacturing quality compliance degree of the concrete precast beam. The specific evaluation method of the expected manufacturing quality compliance index of the concrete precast beam is as follows:

[0046]

[0047] In the formula, EQCI represents the expected manufacturing quality compliance index of the concrete precast beam, ECF represents the environmental compliance factor of the expected manufacturing process of the concrete precast beam, WOC represents the concrete water-cement ratio of the concrete precast beam, VA represents the vibration amplitude dispersion value of the concrete precast beam, MOP g represents the average prestress of the gth sample detection position area of the concrete precast beam, W represents the specific gravity factor corresponding to the environmental compliance factor, AWOC represents the concrete reference water-cement ratio, and AMOP gH represents the expected manufacturing quality compliance index ratio factor corresponding to the preset unit value of the vibration amplitude dispersion value in the control database, e is a natural constant, g is the number of each sample detection position area, g = 1, 2, 3,..., j, j is the total number of sample detection position areas.

[0048] It needs to be explained that the environmental compliance of the expected manufacturing process of the concrete precast beam is the premise of guaranteeing the expected manufacturing quality compliance of the concrete precast beam, so the environmental compliance factor of the expected manufacturing process of the concrete precast beam is put into the expected manufacturing quality compliance index of the concrete precast beam for comprehensive analysis. A precise and reasonable water-cement ratio can make the concrete exhibit the best physical and chemical properties, ensuring that the concrete reaches the expected strength, durability and work performance. However, when the water-cement ratio of the concrete deviates significantly from its reference value, the overall performance of the concrete will decrease sharply, resulting in obvious quality problems during the pouring process. This deviation in water-cement ratio not only directly weakens the strength of the concrete, but also significantly reduces the uniformity of the concrete during the pouring process. As the core link in concrete construction, the effect of vibration depends largely on the uniformity of the concrete. When the water-cement ratio of the concrete deviates from its reference value, the concrete during the vibration process will become difficult to uniformly vibrate, and the dispersion degree of the vibration amplitude will increase significantly, resulting in defects such as voids and bubbles in the concrete. These defects not only reduce the density and strength of the concrete, but also seriously affect the mechanical properties and durability of the concrete precast beam. Ultimately, these internal defects will further cause the average prestress of the concrete precast beam in the corresponding sample detection position area to deviate significantly from its reference value. If the average prestress deviates significantly from its reference value, it will cause the concrete precast beam to crack or break prematurely during the stress process, seriously affecting the performance of the concrete precast beam, thereby having a profound and adverse impact on the overall quality and performance of the concrete precast beam.

[0049] The specific gravity factor corresponding to the environmental compliance factor of the expected manufacturing process of the concrete precast beam represents the proportion of the environmental compliance factor of the expected manufacturing process of the concrete precast beam in the expected manufacturing quality compliance index of the concrete precast beam. The control database stores the corresponding relationship of the specific gravity factor, for example, the environmental compliance factor of the expected manufacturing process of the concrete precast beam can be input into the control database, and the control database automatically matches the specific gravity factor corresponding to the environmental compliance factor according to the preset corresponding relationship of the specific gravity factor.

[0050] The expected manufacturing quality compliance index ratio factor corresponding to the unit value of the vibration amplitude dispersion value represents the degree of influence of the unit value of the vibration amplitude dispersion value on the expected manufacturing quality compliance index of the precast concrete beam. The corresponding relationship of the ratio factor is stored in the control database. For example, the vibration amplitude dispersion value can be input into the control database. The control database automatically matches the expected manufacturing quality compliance index ratio factor corresponding to the unit value of the vibration amplitude dispersion value according to the preset corresponding relationship of the ratio factor.

[0051] Step three, if the expected manufacturing quality compliance index of the precast concrete beam is less than or equal to the expected manufacturing quality compliance threshold, the expected manufacturing process parameters of the precast concrete beam are controlled and adjusted. If the expected manufacturing quality compliance index of the precast concrete beam is greater than the expected manufacturing quality compliance threshold, the expected manufacturing process parameters of the precast concrete beam are applied to the actual construction.

[0052] Specifically, the control and adjustment of the expected manufacturing process parameters of the precast concrete beam is specifically the control and adjustment process as follows:

[0053] The expected manufacturing quality compliance threshold is subtracted from the expected manufacturing quality compliance index of the concrete precast beam, and the result is marked as the expected manufacturing quality compliance index deviation value of the concrete precast beam. According to the expected manufacturing quality compliance index deviation value of the concrete precast beam, the adjustment set of the expected manufacturing process parameters is matched. The adjustment set of the expected manufacturing process parameters corresponding to each expected manufacturing quality compliance index deviation value interval is stored in the control database. In an example embodiment, assuming that the expected manufacturing quality compliance index deviation value of a certain concrete precast beam is Z, which belongs to the expected manufacturing quality compliance index deviation value interval [Z-12%, Z+28%] stored in the control database, the adjustment set of the expected manufacturing process parameters corresponding to the expected manufacturing quality compliance index deviation value interval [Z-12%, Z+28%] includes: increasing the cement dosage to 1.2 times the expected dosage, increasing the vibrator vibration frequency to 1.5 times the expected vibration frequency, reducing the vibrator vibration amplitude to 0.8 times the expected vibration amplitude, increasing the use of intelligent grouting equipment, using the intelligent grouting equipment to pour the cement slurry from the other end of the hole until the entire hole is filled, and applying a positive pressure of 0.7 MPa to improve the fullness and density of the prestressed hole grouting, advancing the box girder stripping time by 2 hours compared to the expected stripping time, adjusting the concrete water-cement ratio of the concrete precast beam to the concrete reference water-cement ratio, and adjusting the average prestress of each detection position area to the corresponding reference average prestress. The adjustment set of the expected manufacturing process parameters matched in this embodiment includes: increasing the cement dosage to 1.2 times the expected dosage, increasing the vibrator vibration frequency to 1.5 times the expected vibration frequency, reducing the vibrator vibration amplitude to 0.8 times the expected vibration amplitude, increasing the use of intelligent grouting equipment, using the intelligent grouting equipment to pour the cement slurry from the other end of the hole until the entire hole is filled, and applying a positive pressure of 0.7 MPa to improve the fullness and density of the prestressed hole grouting, advancing the box girder stripping time by 2 hours compared to the expected stripping time, adjusting the concrete water-cement ratio of the concrete precast beam to the concrete reference water-cement ratio, and adjusting the average prestress of each detection position area to the corresponding reference average prestress.

[0054] The expected manufacturing process parameters of the concrete precast beam are updated according to the adjustment set of the expected manufacturing process parameters, and the expected manufacturing quality compliance index of the concrete precast beam is re-evaluated, thereby completing the control adjustment of the expected manufacturing process parameters of the concrete precast beam; it needs to be explained that the adjustment set of the expected manufacturing process parameters is personalized matched according to the expected manufacturing quality compliance index deviation value of the concrete precast beam, and the adjustment set is strictly tested, verified and optimized by the project engineer to ensure that they can effectively improve the manufacturing quality of the concrete precast beam, so that the re-evaluation of the expected manufacturing quality compliance index of the concrete precast beam can meet the requirement of being greater than the expected manufacturing quality compliance threshold; the above-mentioned updating of the expected manufacturing process parameters of the concrete precast beam according to the adjustment set of the expected manufacturing process parameters, for example, the cement dosage in the expected manufacturing process parameters of the concrete precast beam is X tons, and the adjustment set contains increasing the cement dosage to 1.2 times of the expected dosage, then the cement dosage in the expected manufacturing process parameters of the concrete precast beam is updated to 1.2X tons, and the updating process of other parameters is consistent with the updating process of the cement dosage.

[0055] Step four, collecting the pollution parameters of the actual manufacturing process of the concrete precast beam, determining the environmental pollution index of the actual manufacturing process of the concrete precast beam, thereby providing management feedback for the actual manufacturing process of the concrete precast beam.

[0056] In a specific embodiment, the present application can accurately determine the environmental pollution index of the actual manufacturing process of the concrete precast beam by collecting the pollution parameters of the actual manufacturing process of the concrete precast beam in detail, which provides timely and accurate management feedback for the actual manufacturing process of the concrete precast beam. With this feedback mechanism, environmental pollution problems in the manufacturing of concrete precast beams can be quickly identified and solved, effectively reducing the risk of corrosion of concrete precast beams caused by environmental pollution.

[0057] Specifically, the management feedback for the actual manufacturing process of the concrete precast beam is as follows:

[0058] The environmental pollution index of the actual manufacturing process of the concrete precast beam is compared with the environmental pollution threshold value. If the environmental pollution index of the actual manufacturing process of the concrete precast beam is greater than the environmental pollution threshold value, an environmental pollution management set is generated according to the environmental pollution index of the actual manufacturing process of the concrete precast beam, and management feedback is performed on the actual manufacturing process of the concrete precast beam based on the environmental pollution management set. The environmental pollution threshold value represents the minimum value of the reasonable range of the environmental pollution index of the actual manufacturing process of the concrete precast beam and is extracted from a control database. The control database stores the pollution levels corresponding to each environmental pollution index interval. In an example embodiment, it is assumed that the environmental pollution index of the actual manufacturing process of the concrete precast beam is HM, which belongs to the environmental pollution index interval [HM-19%, HM+21%], and the pollution level corresponding to the environmental pollution index interval [HM-19%, HM+21%] is level three. The environmental pollution management set corresponding to the pollution level of level three is queried from the control database, which includes: replacing the catalyst in the catalytic oxidation device for waste gas treatment, ensuring that the initial activity of the catalyst is higher than 95%, and replacing the catalyst when the activity of the catalyst is lower than 80%; controlling the catalytic oxidation reaction to be performed within a temperature range of 300-400 degrees Celsius, controlling the oxygen concentration during the reaction to be within a range of 5%-15%; adding G tons of coagulant to the sedimentation tank for waste water treatment, and adjusting the sedimentation time to 2 hours. The environmental pollution management set in this embodiment includes: replacing the catalyst in the catalytic oxidation device for waste gas treatment, ensuring that the initial activity of the catalyst is higher than 95%, and replacing the catalyst when the activity of the catalyst is lower than 80%; controlling the catalytic oxidation reaction to be performed within a temperature range of 300-400 degrees Celsius, controlling the oxygen concentration during the reaction to be within a range of 5%-15%; adding G tons of coagulant to the sedimentation tank for waste water treatment, and adjusting the sedimentation time to 2 hours. Based on the environmental pollution management set, the environmental supervision project team manages the actual manufacturing process of the concrete precast beam according to the environmental pollution management set and the actual situation. If the management is directly performed according to the environmental pollution management set, the environmental pollution management set does not need to be updated. If the management is adjusted based on the environmental pollution management set, the environmental supervision project team needs to update and adjust the environmental pollution management set in the control database, thereby completing the management feedback on the actual manufacturing process of the concrete precast beam.

[0059] If the environmental pollution index of the actual manufacturing process of the concrete precast beam is less than or equal to the environmental pollution threshold value, the pollution parameters of the actual manufacturing process of the concrete precast beam are continuously monitored and collected.

[0060] Specifically, the pollution parameters of the actual manufacturing process of the concrete precast beam include waste water pollution parameters of the actual manufacturing process of the concrete precast beam and waste gas pollution parameters of the actual manufacturing process of the concrete precast beam. Further, the environmental pollution index of the actual manufacturing process of the concrete precast beam is determined as follows:

[0061] The wastewater pollution parameter of the actual manufacturing process of the concrete precast beam includes the average pH value of the wastewater in the pollution monitoring period of the actual manufacturing process of the concrete precast beam and the average concentration of various pollutants in the wastewater in the pollution monitoring period of the actual manufacturing process of the concrete precast beam. The pollution monitoring period refers to the period of monitoring the pollution of the actual manufacturing process of the concrete precast beam, and the specific duration is determined by the environmental supervision department. The average pH value of the wastewater in the pollution monitoring period of the actual manufacturing process of the concrete precast beam refers to the average value obtained by testing the pH value of the wastewater in the environment during the pollution monitoring period of the actual manufacturing process of the concrete precast beam. The method of obtaining the average pH value of the wastewater in the environment during the pollution monitoring period of the actual manufacturing process of the concrete precast beam is consistent with the method of obtaining the average pH value of the water used in the environment during the pollution monitoring period of the actual manufacturing process of the concrete precast beam. The average concentration of various pollutants in the wastewater in the pollution monitoring period of the actual manufacturing process of the concrete precast beam refers to the average concentration of various pollutants in the wastewater in the pollution monitoring period of the actual manufacturing process of the concrete precast beam. The wastewater samples can be collected during the pollution monitoring period, and the water quality monitoring instruments such as gas chromatograph can be used to measure the wastewater samples, and the average concentration of various pollutants can be obtained by averaging the concentration of the same type of pollutants. The pollutants refer to compounds that have corrosion effect on the concrete precast beam, including sulfide type (such as sulfurous acid and sulfuric acid) and nitrogen oxide type (mainly in the form of nitrite and nitrate).

[0062] The exhaust gas pollution parameter of the actual manufacturing process of the concrete precast beam includes the average concentration of various exhaust gases in the pollution monitoring period of the actual manufacturing process of the concrete precast beam. The average concentration of various exhaust gases in the pollution monitoring period of the actual manufacturing process of the concrete precast beam has the same meaning and obtaining method as the average concentration of various harmful gases in the environment during the pollution monitoring period of the actual manufacturing process of the concrete precast beam. The various exhaust gases include sulfide type (such as sulfur dioxide) and volatile organic matter type (such as nitrogen-containing organic matter).

[0063] The expected manufacturing quality compliance index of the concrete precast beam, the average pH value of the wastewater in the pollution monitoring period of the actual manufacturing process of the concrete precast beam, the average concentration of various pollutants in the wastewater in the pollution monitoring period of the actual manufacturing process of the concrete precast beam, and the average concentration of various exhaust gases in the pollution monitoring period of the actual manufacturing process of the concrete precast beam are comprehensively analyzed to obtain the environmental pollution index of the actual manufacturing process of the concrete precast beam. In this embodiment, the environmental pollution index of the actual manufacturing process of the concrete precast beam refers to the numerical value of the environmental pollution degree of the actual manufacturing process of the concrete precast beam. The specific determination method of the environmental pollution index of the actual manufacturing process of the concrete precast beam is as follows:

[0064]

[0065] In the formula, PIE represents the environmental pollution index of the actual manufacturing process of the concrete precast beam, EQCI represents the expected manufacturing quality compliance index of the concrete precast beam, JD represents the average pH value of the wastewater in the pollution monitoring period of the actual manufacturing process of the concrete precast beam, ΔJD represents the preset reference average pH value of the wastewater in the control database, WT c represents the average concentration of the cth type of pollutant in the pollution monitoring period of the wastewater of the actual manufacturing process of the concrete precast beam, LT m represents the average concentration of the mth type of exhaust gas in the pollution monitoring period of the actual manufacturing process of the concrete precast beam, Y represents the specific gravity factor corresponding to the expected manufacturing quality compliance index in the control database, nu1 represents the environmental pollution index proportional factor corresponding to the unit value of the average concentration of the pollutant in the control database, nu2 represents the environmental pollution index proportional factor corresponding to the unit value of the average concentration of the exhaust gas in the control database, c is the number of each type of pollutant, c = {1, 2, 3, …, k}, k is the total number of types of pollutants, m is the number of each type of exhaust gas, m = {1, 2, 3, …, p}, and p is the total number of types of exhaust gas.

[0066] The above-mentioned reference average pH value of the wastewater, represents the reference value of the average pH value of the wastewater in the pollution monitoring period of the actual manufacturing process of the concrete precast beam.

[0067] The above-mentioned specific gravity factor corresponding to the expected manufacturing quality compliance index, represents the proportion of the expected manufacturing quality compliance index of the concrete precast beam to the environmental pollution index of the actual manufacturing process of the concrete precast beam, and the control database stores the corresponding relationship of the specific gravity factor, for example, the expected manufacturing quality compliance index of the concrete precast beam can be input into the control database, and the control database automatically matches the specific gravity factor corresponding to the expected manufacturing quality compliance index according to the preset corresponding relationship of the specific gravity factor.

[0068] The above-mentioned environmental pollution index proportional factor corresponding to the unit value of the average concentration of the pollutant, represents the value of the influence degree of the unit value of the average concentration of the pollutant on the environmental pollution index of the actual manufacturing process of the concrete precast beam, and the control database stores the corresponding relationship of the proportional factor, for example, the average concentration of the pollutant can be input into the control database, and the control database automatically matches the environmental pollution index proportional factor corresponding to the unit value of the average concentration of the pollutant according to the preset corresponding relationship of the proportional factor.

[0069] The environmental pollution index proportional factor corresponding to the unit value of the average concentration of the exhaust gas indicates the degree of influence of the unit value of the average concentration of the exhaust gas on the environmental pollution index of the actual manufacturing process of the precast concrete beam. The control database stores the corresponding relationship of the proportional factor. For example, the average concentration of the exhaust gas can be input into the control database. The control database automatically matches the environmental pollution index proportional factor corresponding to the unit value of the average concentration of the exhaust gas according to the preset corresponding relationship of the proportional factor.

[0070] It should be explained that ensuring manufacturing quality compliance is the basic condition for maintaining low environmental pollution level. Therefore, the expected manufacturing quality compliance index of the precast concrete beam is integrated into the comprehensive analysis of the environmental pollution index of the actual manufacturing process of the precast concrete beam. If the average pH of the wastewater during the pollution monitoring period significantly deviates from the reference average pH of the wastewater, it indicates a high pollution level, further indicating a high average concentration of pollutants in the wastewater and a high concentration of pollutants in the exhaust gas. The pollutants in the exhaust gas may dissolve in the wastewater, further exacerbating the deviation of the pH of the wastewater, forming a vicious cycle. In addition, the wastewater will infiltrate into the soil, exacerbating the deviation of the pH of the wastewater from its reference value, thereby causing additional adverse effects on the mixing process of the concrete, etc. At the same time, the harmful components in the exhaust gas may also react with the elements in the precast concrete beam, causing corrosion and cracking of the precast concrete beam, etc. Therefore, the above parameters need to be comprehensively analyzed to determine the environmental pollution level of the actual manufacturing process of the precast concrete beam, so as to effectively manage and control it. Not only can it significantly reduce the direct harm of wastewater and exhaust gas to the precast concrete beam, such as avoiding corrosion and strength reduction of the concrete, etc., but also can promote the rational use and recycling of resources, reduce energy consumption and emissions during the manufacturing process. More importantly, this comprehensive evaluation method helps to discover and solve environmental pollution problems in a timely manner, reduces the migration and accumulation of pollutants, and thus protects the natural ecological system of soil and water sources, etc., providing a solid guarantee for the green development of the precast concrete beam manufacturing industry.

[0071] In one specific embodiment, the present application provides a quality control method for a concrete precast beam, which precisely acquires and analyzes environmental parameters belonging to the expected manufacturing process of the concrete precast beam, and then individually matches the optimal manufacturing process compliance parameter set of the concrete precast beam, and through the deep comprehensive analysis of the expected manufacturing process parameters and the compliance parameter set of the concrete precast beam, the expected manufacturing quality compliance degree of the concrete precast beam can be accurately identified, and targeted adjustment and optimization can be carried out accordingly, so as to ensure that the precast beam produced has excellent quality, and in addition, pollution parameters in the actual manufacturing process of the concrete precast beam are collected and analyzed, and manufacturing pollution is comprehensively managed, so as to ensure accurate and efficient production while ensuring environmental green protection. This quality control method not only improves the production efficiency and product quality of the concrete precast beam, but also effectively reduces environmental pollution in the production process, achieving a win-win of economic benefit and ecological benefit.
