Technical Field
[0001] The present invention relates to the technical field of building construction, and particularly to a construction method for one-time forming of a corundum wear-resistant floor. Background Art
[0002] The corundum wear-resistant floor is a common wear-resistant floor material, usually used for floors that need to withstand high-intensity wear in industrial sites, commercial buildings, public areas, etc. The construction of the corundum wear-resistant floor requires professional technology and experience. The construction process includes concrete pouring, concrete surface treatment, corundum spreading, etc. Among them, the spreading of corundum needs to ensure the uniformity of spreading and the consistency of the bonding effect between corundum and concrete to obtain the required wear-resistant layer thickness and appearance quality, and maintain the flatness and consistency of the floor. However, the construction site environment is changeable and complex, and the spreading process of corundum is easily affected by the environment. Controlling the details of corundum spreading has become an important improvement link in the current construction of corundum wear-resistant floor forming.
[0003] For example, Chinese Patent Application: CN116856658A, which discloses a construction method for a large-area corundum floor, including the following steps: preliminary calibration of the floor elevation; floor zoning: taking the center line in the width direction of the floor foundation as the reference, dividing the floor foundation into a first area and a second area, dividing the first area into multiple first sub-areas, and dividing the second area into multiple second sub-areas; floor foundation treatment; preparing screeds: preparing screeds at both ends of the first area along its length direction, between each adjacent two first sub-areas, at both ends of the second area along its length direction, and between each adjacent two second sub-areas; pouring concrete: pouring the concrete into each first sub-area and each second sub-area; leveling with a laser screed; spreading corundum; curing; cutting joints.
[0004] The following problems also exist in the prior art:
[0005] The prior art does not consider that the influence of air flow and environmental temperature on the large-area concrete surface is different, resulting in different degrees of condensation on the concrete surface. The prior art cannot quantify the difference in the bonding effect between corundum and concrete according to the dusting phenomenon during the spreading process of corundum on the concrete surface, and cannot adjust the construction method according to the difference in the bonding effect between corundum and concrete, affecting the consistency of the bonding effect between corundum and concrete. Summary of the Invention
[0006] Therefore, the present invention provides a construction method for one-time forming of a corundum wear-resistant floor to overcome the problems that the prior art cannot quantify the difference in the bonding effect between corundum and concrete according to the dusting phenomenon during the spreading process of corundum on the concrete surface, and cannot adjust the construction method according to the difference in the bonding effect between corundum and concrete.
[0007] To achieve the above object, the present invention provides a construction method for one-time forming of a carborundum wear-resistant floor, including:
[0008] Step S1, leveling the completed cast-in-place base concrete and dividing the base concrete into several sub-regions;
[0009] Step S2, spreading carborundum on each sub-region, obtaining in real time the dust concentration value during the process of spreading carborundum on each sub-region, plotting the concentration change curve of the dust concentration value changing with time, and determining whether to mark the sub-region as a characteristic dominant sub-region based on the dust concentration fluctuation value corresponding to the concentration change curve;
[0010] Step S3, determining the concentration change curve corresponding to each characteristic dominant sub-region, calculating the condensation state characterization coefficient based on the dust concentration value and the slope value corresponding to the concentration change curve, and determining the bonding state of the carborundum spread based on the difference situation of the condensation state characterization coefficients corresponding to the characteristic dominant sub-regions;
[0011] Step S4, selecting the construction method for each sub-region based on the bonding state;
[0012] Among them, the construction method includes controlling the troweling machine to adjust the operation duration of repeatedly troweling the carborundum layer in the characteristic dominant sub-region, or screening several sub-regions based on the condensation state characterization coefficient, calculating the surface height difference of the screened sub-regions to determine whether the carborundum spreading effect meets the preset standard;
[0013] Step S5, controlling the troweling machine to repeatedly trowel the sub-regions where the carborundum spreading effect does not meet the preset standard, and performing secondary spreading and troweling of carborundum on each completed troweled sub-region;
[0014] Step S6, polishing each sub-region to obtain a carborundum wear-resistant floor.
[0015] Further, in the step S2, the dust concentration fluctuation value is calculated according to formula (1);
[0016] ,
[0017] In formula (1), Dc is the dust concentration fluctuation value, D i is the dust concentration value corresponding to the i-th collection point on the concentration change curve, i = 1, 2, 3... n, n is the number of preset collection points on the concentration change curve, D av is the average value of the dust concentration values corresponding to n collection points on the concentration change curve.
[0018] Further, in the step S2, the process of determining whether to mark the sub-region as a feature dominant sub-region is as follows:
[0019] Compare the dust concentration fluctuation value with a preset dust concentration fluctuation value threshold;
[0020] If the dust concentration fluctuation value is greater than the dust concentration fluctuation value threshold, it is determined that the sub-region is marked as a feature dominant sub-region.
[0021] Further, in the step S3, it also includes dividing the concentration change curve into several curve segments, calculating the slope value of each curve segment based on the coordinate values of the start and end points of the curve segment, determining the absolute value of the slope based on the slope values of each curve segment, and screening out the maximum value of the absolute value of the slope.
[0022] Further, in the step S3, the condensation state characterization coefficient is calculated according to formula (2);
[0023] ,
[0024] In formula (2), E is the condensation state characterization coefficient, D max is the maximum value of the dust concentration value on the concentration change curve, D min is the minimum value of the dust concentration value on the concentration change curve, k max is the maximum value of the absolute value of the slope, k 0 is a preset slope reference value, α is a dust concentration weight coefficient, and β is a slope weight coefficient.
[0025] Further, in the step S3, the process of determining the bonding state of the emery cloth spreading is as follows:
[0026] Calculate the standard deviation of the condensation state characterization coefficient based on the condensation state characterization coefficients corresponding to several sub-regions, and compare the standard deviation of the condensation state characterization coefficient with a preset standard deviation reference value of the condensation state characterization coefficient;
[0027] If the standard deviation of the condensation state characterization coefficient is less than or equal to the standard deviation reference value of the condensation state characterization coefficient, it is determined that the bonding state of the emery cloth spreading is a uniform bonding state;
[0028] If the standard deviation of the condensation state characterization coefficient is greater than the standard deviation reference value of the condensation state characterization coefficient, it is determined that the bonding state of the emery cloth spreading is a non-uniform bonding state.
[0029] Further, in the step S4, the process of selecting the construction method for each sub-region is as follows:
[0030] If the bonding state is a uniform bonding state, control the troweling machine to adjust the operation duration of repeatedly troweling the emery layer within the feature dominant sub-region;
[0031] If the bonding state is a non-uniform bonding state, screen several sub-regions based on the setting state characterization coefficient, calculate the surface height difference of the screened sub-regions, so as to determine whether the emery spreading effect meets the preset standard.
[0032] Further, in step S4, the operation duration of controlling the troweling machine to repeatedly trowel the emery layer within the feature dominant sub-region is adjusted based on the standard deviation of the setting state characterization coefficient, and the operation duration is positively correlated with the standard deviation of the setting state characterization coefficient.
[0033] Further, in step S4, it also includes screening the sub-region corresponding to the maximum value of the setting state characterization coefficient as the first feature sub-region, screening the sub-region corresponding to the minimum value of the setting state characterization coefficient as the second feature sub-region, determining the surface height of the first feature sub-region as the first feature surface height, determining the surface height of the second feature sub-region as the second feature surface height, and determining the difference between the first feature surface height and the second feature surface height as the surface height difference.
[0034] Further, in step S4, the process of determining whether the emery spreading effect meets the preset standard is as follows:
[0035] Compare the surface height difference with a preset surface height difference threshold;
[0036] If the surface height difference is greater than the surface height difference threshold, it is determined that the emery spreading effect does not meet the preset standard.
[0037] Compared with the prior art, the beneficial effects of the present invention are as follows. The present invention divides the base concrete into several sub-regions, and during the process of spreading emery on each sub-region, the dust concentration value of the emery is obtained in real time, a concentration change curve is plotted, and it is determined whether to mark the sub-region as a feature dominant sub-region based on the dust concentration fluctuation value corresponding to the concentration change curve. The setting state characterization coefficient is calculated through the dust concentration value and the slope value corresponding to the concentration change curve. The bonding state of the emery spreading is determined through the difference situation of the setting state characterization coefficient, so as to select the construction method for each sub-region. Through secondary spreading, troweling and polishing of the emery, an emery wear-resistant floor is finally obtained. Furthermore, it realizes the quantification of the bonding effect difference between the emery and the concrete according to the dust phenomenon during the spreading process of the emery on the concrete surface, and adjusts the construction method according to the bonding effect difference between the emery and the concrete, improving the consistency of the bonding effect between the emery and the concrete.
[0038] In particular, the present invention obtains the dust concentration values during the emery spreading process for each sub-region, and plots the concentration change curve of the dust concentration values over time. During the emery spreading link on the concrete surface, due to the differences in temperature effects on each region of the large-area concrete and the differences in air convection conditions in different regions, there are differences in the setting progress of each region of the concrete. When emery is spread in the region with a slower setting progress, the surface water content is relatively large, and the dust raising phenomenon generated during the emery spreading link is not obvious. On the contrary, when emery is spread in the region with a faster setting progress, the surface water content is relatively small, and the dust raising phenomenon generated during the emery spreading link is obvious. The present invention realizes the intuitive acquisition of the change in the dust raising degree during emery spreading by obtaining the concentration change curve of the dust concentration values during the emery spreading process for each sub-region in real time.
[0039] In particular, the present invention determines whether to mark the sub-region as a characteristic dominant sub-region based on the dust concentration fluctuation value corresponding to the concentration change curve. During the actual emery spreading process, if the monitored dust concentration fluctuation value in the current region is large, it indicates that there are obvious differences in the setting progress of the concrete in this region, and different degrees of dust raising are generated on the surfaces of concretes with different setting progress. Furthermore, the present invention realizes the characterization of the difference in the concrete setting progress based on the dust raising phenomenon generated by the emery spreading on the concrete surface.
[0040] In particular, the present invention calculates the setting state characterization coefficient based on the dust concentration value and the slope value corresponding to the concentration change curve. As is well known to those skilled in the art, the greater the difference between the average value of the maximum and minimum dust concentration values of the emery in the current region and the average value of the dust concentration values of the overall curve, the worse the uniformity of the dust concentration value distribution in this region, the more obvious the fluctuation degree of the concentration value, and the greater the difference in the setting progress of the concrete. Similarly, the greater the absolute value of the maximum slope of the curve segment in the concentration change curve, the greater the degree of sudden change in the dust concentration during the emery spreading process, the greater the difference in the setting progress of the concrete, and the more likely it is to occur the difference phenomenon in the bonding effect between the concrete and the emery. The present invention combines the two to realize the intuitive quantification of the difference degree in the bonding effect between the emery and the concrete caused by the concrete setting difference, and avoids the inaccuracy of the calculation result.
[0041] In particular, the present invention controls the troweling machine to adjust the operation duration of repeatedly troweling the carborundum layer within the feature dominant sub-region. Under the condition that the difference in the bonding effect between the carborundum and the concrete is not obvious, it is only necessary to repeatedly trowel the selected sub-regions with strong dust data fluctuations for a longer time, avoiding the difference in the bonding effect of the carborundum caused by the difference in the concrete setting progress in the regions with obvious dust data fluctuations, resulting in uneven distribution of the carborundum. It realizes the adjustment of the construction method according to the difference in the bonding effect between the carborundum and the concrete, and improves the consistency of the bonding effect between the carborundum and the concrete.
[0042] In particular, the present invention screens a number of sub-regions through the setting state characterization coefficient, calculates the surface height difference of the selected sub-regions to determine whether the carborundum spreading effect meets the preset standard. Under the condition that the difference in the bonding effect between the carborundum and the concrete is obvious, it is necessary to screen the sub-regions with the largest difference in the concrete setting progress, calculate the surface height difference between the selected sub-regions. During the actual carborundum spreading process, due to the different shrinkage states of the concrete in the sub-regions with large differences in the concrete setting progress, there is a height difference in the overall height between the regions. The present invention directly judges the horizontal height of the regions with different concrete progress, and efficiently and scientifically realizes the adjustment of the construction method, improving the consistency of the bonding effect between the carborundum and the concrete.

[0051] Please refer to Figure 1 as shown, which is a schematic structural diagram of the construction method for one-time forming of a carborundum wear-resistant floor according to an embodiment of the present invention. The construction method for one-time forming of a carborundum wear-resistant floor of the present invention includes:
[0052] Step S1, leveling the completed cast-in-place base concrete and dividing the base concrete into several sub-regions;
[0053] Step S2, spreading carborundum on each sub-region, obtaining in real time the dust concentration value during the process of spreading carborundum on each sub-region, plotting the concentration change curve of the dust concentration value changing with time, and determining whether to mark the sub-region as a characteristic dominant sub-region based on the dust concentration fluctuation value corresponding to the concentration change curve;
[0054] Step S3, determining the concentration change curve corresponding to each characteristic dominant sub-region, calculating the condensation state characterization coefficient based on the dust concentration value and the slope value corresponding to the concentration change curve, and determining the bonding state of the carborundum spreading based on the difference situation of the condensation state characterization coefficients corresponding to the characteristic dominant sub-regions;
[0055] Step S4, selecting the construction method for each sub-region based on the bonding state;
[0056] Among them, the construction method includes controlling the troweling machine to adjust the operation duration of repeatedly leveling the carborundum layer within the characteristic dominant sub-region, or screening several sub-regions based on the condensation state characterization coefficient, calculating the surface height difference of the screened sub-regions to determine whether the carborundum spreading effect meets the preset standard;
[0057] Step S5: Control the troweling machine to repeatedly level the sub-areas where the effect of the emery spreading does not meet the preset standard, and perform secondary emery spreading and leveling on each completed sub-area.
[0058] Step S6: Polish each sub-area to obtain an emery wear-resistant floor.
[0059] Specifically, the present invention does not limit the method for obtaining the dust concentration value during the emery spreading process. In the embodiment of the present invention, the dust concentration value can be obtained through a dust concentration sensor provided on the emery spreader. This technology is familiar to those skilled in the art and is widely used in the construction site dust monitoring process, so it will not be elaborated here.
[0060] Specifically, the present invention does not limit the method for drawing the concentration change curve of the dust concentration value over time. In the embodiment of the present invention, data processing software and data visualization tools can be selected. The collected dust concentration values can be processed and plotted through the functions and tools built in the data processing software to generate a concentration change curve, and displayed through the data visualization tools. This is prior art and will not be elaborated here.
[0061] Specifically, the present invention does not limit the method for measuring and calculating the surface height difference of each area of the concrete. In the embodiment of the present invention, a laser leveling instrument can be used to emit a laser line parallel to the ground, and a level on the receiver can be used to determine the height difference of the measurement points. Measurements can be carried out in different areas of the concrete surface to determine the height difference. This is prior art and will not be elaborated here.
[0062] Specifically, in the present invention, by obtaining the dust concentration value during the emery spreading process for each sub-area and drawing the concentration change curve of the dust concentration value over time, during the emery spreading link on the concrete surface, due to the different temperature effects on each area of the large-area concrete and the different air convection conditions in different areas, there are differences in the setting progress of each area of the concrete. When the emery is spread in the area with a slower setting progress, the surface water content is relatively large, and the dust generation phenomenon during the emery spreading link is not obvious. On the contrary, when the emery is spread in the area with a faster setting progress, the surface water content is relatively small, and the dust generation phenomenon during the emery spreading link is obvious. The present invention realizes the intuitive acquisition of the change in the dust generation degree during the emery spreading by obtaining the concentration change curve of the dust concentration value during the emery spreading process for each sub-area in real time.
[0063] Specifically, please refer to Figure 2 As shown, it is the logic flow chart for determining whether to mark a sub-area as a feature dominant sub-area in the embodiment of the present invention. In step S2, the dust concentration fluctuation value is calculated according to formula (1);
[0064] ,
[0065] In formula (1), Dc is the fluctuation value of the dust concentration, and D i is the dust concentration value corresponding to the i-th collection point on the concentration change curve, where i = 1, 2, 3... n, and n is the number of preset collection points on the concentration change curve. D av is the average value of the dust concentration values corresponding to the n collection points on the concentration change curve.
[0066] Specifically, in step S2, the process of determining whether to mark the sub-region as a feature dominant sub-region is as follows:
[0067] Compare the dust concentration fluctuation value Dc with the preset dust concentration fluctuation value threshold Dc 0 ;
[0068] If the dust concentration fluctuation value Dc is less than or equal to the dust concentration fluctuation value threshold Dc 0 , it is determined not to mark the sub-region;
[0069] If the dust concentration fluctuation value Dc is greater than the dust concentration fluctuation value threshold Dc 0 , it is determined to mark the sub-region as a feature dominant sub-region.
[0070] In the embodiment of the present invention, the value of the dust concentration fluctuation value threshold Dc 0 is affected by various factors, including construction methods, the use of equipment and control measures, and environmental conditions, etc. Preferably, the value range of the dust concentration fluctuation value threshold Dc 0 is [3, 5], and the interval unit is mg / m 3 .
[0071] Specifically, the present invention determines whether to mark a sub-region as a feature dominant sub-region through the dust concentration fluctuation value corresponding to the concentration change curve. During the actual process of spreading emery, if the monitored dust concentration fluctuation value in the current region is large, it indicates that there are obvious differences in the concrete setting progress in this region, and different degrees of dust emission are generated on the surfaces of concrete with different setting progresses. Furthermore, the present invention realizes the characterization of the differences in concrete setting progress based on the dust emission phenomenon generated by spreading emery on the concrete surface.
[0072] Specifically, in step S3, it further includes dividing the concentration change curve into several curve segments, calculating the slope value of the curve segment based on the coordinate values of the start and end points of the curve segment, determining the absolute value of the slope based on the slope values of each curve segment, and screening out the maximum value of the absolute value of the slope.
[0073] Specifically, please refer to Figure 3 shown in andFigure 4 As shown, in step S3, the condensation state characterization coefficient is calculated according to formula (2);
[0074] ,
[0075] In formula (2), E is the condensation state characterization coefficient, D max is the maximum value of the dust concentration on the concentration change curve, D min is the minimum value of the dust concentration on the concentration change curve, k max is the maximum value of the absolute value of the slope, k 0 is the preset slope reference value, α is the dust concentration weight coefficient, β is the slope weight coefficient, and α + β = 1.
[0076] Please continue to refer to Figure 4 shown, which is a schematic diagram of the concentration change curve of the embodiment of the present invention. Determine the maximum value D of the dust concentration value in the concentration change curve in the figure max and the minimum value D of the dust concentration value min .
[0077] In the embodiment of the present invention, the value of the slope reference value k 0 is obtained based on pre-test calculation. In the concentration change curve of the dust concentration value during the spreading process of emery of the same specification, the average value of the absolute values of the slopes of several curve segments is calculated, and the average value is determined as the slope reference value k 0 . The dust concentration weight coefficient α and the slope weight coefficient β can be set by those skilled in the art according to the influence degree of the dust concentration and the slope on the calculation result in historical data. Preferably, the dust concentration weight coefficient α = 0.6 and the slope weight coefficient β = 0.4 can be set.
[0078] Specifically, the present invention calculates the condensation state characterization coefficient through the dust concentration value and the slope value corresponding to the concentration change curve. As is well known to those skilled in the art, the greater the difference between the average value of the maximum value and the minimum value of the dust concentration of emery in the current area and the average value of the dust concentration of the overall curve, the worse the uniformity of the dust concentration value distribution in this area, the more obvious the fluctuation degree of the concentration value, the greater the difference in the condensation progress of the concrete is characterized. Similarly, the greater the maximum value of the absolute value of the slope of the curve segment in the concentration change curve, the greater the degree of sudden change of the dust concentration during the spreading process of emery is characterized, the greater the difference in the condensation progress of the concrete is characterized, and the more likely it is to occur the difference phenomenon of the bonding effect between the concrete and the emery. The present invention combines the two, realizes the intuitive quantification of the difference degree of the bonding effect between the emery and the concrete caused by the difference in the concrete condensation, and avoids the inaccuracy of the calculation result.
[0079] Specifically, in the step S3, the process of determining the bonding state of the emery cloth is as follows:
[0080] Based on the condensation state characterization coefficients corresponding to a number of sub-regions, calculate the standard deviation Es of the condensation state characterization coefficients, and compare the standard deviation Es of the condensation state characterization coefficients with a preset reference value Es of the standard deviation of the condensation state characterization coefficients 0 for comparison;
[0081] If the standard deviation Es of the condensation state characterization coefficients is less than or equal to the reference value Es of the standard deviation of the condensation state characterization coefficients 0 , it is determined that the bonding state of the emery cloth is a uniformly bonded state;
[0082] If the standard deviation Es of the condensation state characterization coefficients is greater than the reference value Es of the standard deviation of the condensation state characterization coefficients 0 , it is determined that the bonding state of the emery cloth is a non-uniformly bonded state.
[0083] Preferably, in the embodiment of the present invention, the reference value Es of the standard deviation of the condensation state characterization coefficients 0 has a value range of [0.15, 0.2].
[0084] Specifically, in the step S4, the process of selecting the construction method for each sub-region is as follows:
[0085] If the bonding state is a uniformly bonded state, control the trowel to adjust the operation duration of repeatedly leveling the emery layer in the feature-dominant sub-region;
[0086] If the bonding state is a non-uniformly bonded state, based on the condensation state characterization coefficients, screen a number of sub-regions, calculate the surface height difference of the screened sub-regions, and determine whether the emery cloth application effect meets the preset standard.
[0087] Specifically, in the step S4, the operation duration of controlling the trowel to repeatedly level the emery layer in the feature-dominant sub-region is adjusted based on the standard deviation Es of the condensation state characterization coefficients, and the operation duration is positively correlated with the standard deviation Es of the condensation state characterization coefficients.
[0088] Specifically, the present invention controls the troweling machine to adjust the operation duration of repeatedly troweling the carborundum layer within the feature dominant sub-region. Under the condition that the difference in the bonding effect between the carborundum and the concrete is not obvious, it is only necessary to repeatedly trowel the selected sub-regions with strong dust data fluctuations for a longer time, so as to avoid the difference in the carborundum bonding effect caused by the difference in the concrete setting progress within the regions with obvious dust data fluctuations, resulting in uneven distribution of the carborundum, and realizes adjusting the construction method according to the difference in the bonding effect between the carborundum and the concrete, improving the consistency of the bonding effect between the carborundum and the concrete.
[0089] Specifically, in the step S4, it further includes screening the sub-region corresponding to the maximum value of the setting state characterization coefficient as the first characteristic sub-region, screening the sub-region corresponding to the minimum value of the setting state characterization coefficient as the second characteristic sub-region, determining the surface height of the first characteristic sub-region as the first characteristic surface height, determining the surface height of the second characteristic sub-region as the second characteristic surface height, and determining the difference between the first characteristic surface height and the second characteristic surface height as the surface height difference hc.
[0090] Specifically, in the step S4, the process of determining whether the carborundum spreading effect meets the preset standard is as follows:
[0091] Compare the surface height difference hc with the preset surface height difference threshold hc 0 ;
[0092] If the surface height difference hc is less than or equal to the surface height difference threshold hc 0 , it is determined that the carborundum spreading effect does not meet the preset standard;
[0093] If the surface height difference hc is greater than the surface height difference threshold hc 0 , it is determined that the carborundum spreading effect does not meet the preset standard.
[0094] Preferably, in the embodiment of the present invention, within a range of 2 meters, the value of the surface height difference threshold hc 0 is [4, 5], and the interval unit is mm.
[0095] Specifically, the present invention screens several sub-regions through the condensation state characterization coefficient, calculates the surface height difference of the screened sub-regions to determine whether the effect of emery spreading meets the preset standard. Under the condition that the difference in the bonding effect between emery and concrete is obvious, it is necessary to screen the sub-regions with the largest difference in concrete condensation progress and calculate the surface height difference between the screened sub-regions. During the actual emery spreading process, due to the different shrinkage states of concrete in the sub-regions with a large difference in concrete condensation progress, there is a height difference in the overall height between the regions. The present invention directly judges the horizontal height of the regions with different concrete progress, efficiently and scientifically realizes the adjustment of the construction method, and improves the consistency of the bonding effect between emery and concrete.

The process of determining whether to mark the sub-region as a feature-dominant sub-region is as follows: Comparing the dust concentration fluctuation value with a preset dust concentration fluctuation value threshold; If the dust concentration fluctuation value is greater than the dust concentration fluctuation value threshold, it is determined that the sub-region is marked as a characteristic dominant sub-region; Step S3, determining the concentration change curve corresponding to each characteristic dominant sub-region, calculating the coagulation state characterization coefficient based on the dust concentration value and slope value corresponding to the concentration change curve, and determining the bonding state of the diamond dust spreading based on the difference of the coagulation state characterization coefficients corresponding to the characteristic dominant sub-region;

The condensation state characterization coefficient is calculated according to formula (2); , In formula (2), E is the coefficient representing the condensation state, D max is the maximum value of dust concentration on the concentration variation curve, D min is the minimum dust concentration value on the concentration change curve, k max is the maximum absolute value of the slope, k0 is the preset slope reference value, α is the dust concentration weight coefficient, and β is the slope weight coefficient; The process of determining the bonding state of diamond dust is as follows; Calculating a condensation state characterization coefficient standard deviation based on the condensation state characterization coefficients corresponding to the plurality of sub-regions, and comparing the condensation state characterization coefficient standard deviation with a preset condensation state characterization coefficient standard deviation reference value; If the standard deviation of the coagulation state characterization coefficient is less than or equal to the reference value of the standard deviation of the coagulation state characterization coefficient, it is determined that the bonding state of the diamond dust spreading is a uniform bonding state; If the standard deviation of the coagulation state characterization coefficient is greater than the reference value of the standard deviation of the coagulation state characterization coefficient, it is determined that the bonding state of the diamond dust spreading is an under-uniform bonding state; Step S4, selecting a construction method for each sub-area based on the bonding state; The construction method includes controlling a trowel to adjust the operation time of repeatedly smoothing the corundum layer in the characteristic dominant sub-region, or screening a number of characteristic dominant sub-regions based on the coagulation state characterization coefficient, and calculating the surface height difference of the screened characteristic dominant sub-regions to determine whether the corundum spreading effect meets the preset standard; The process of selecting the construction method for each sub-area is as follows: If the bonding state is a uniform bonding state, controlling the trowel machine to adjust the operation time of repeatedly smoothing the diamond abrasive layer in the characteristic dominant sub-region; If the bonding state is an uneven bonding state, a plurality of characteristic dominant sub-regions are screened based on the coagulation state characterization coefficient, and the surface height difference of the screened characteristic dominant sub-regions is calculated to determine whether the diamond abrasive spreading effect meets the preset standard; The step S4 further includes screening the characteristic dominant sub-region corresponding to the maximum value of the coagulation state characterization coefficient as the first characteristic sub-region, screening the characteristic dominant sub-region corresponding to the minimum value of the coagulation state characterization coefficient as the second characteristic sub-region, determining the surface height of the first characteristic sub-region as the first characteristic surface height, determining the surface height of the second characteristic sub-region as the second characteristic surface height, and determining the difference between the first characteristic surface height and the second characteristic surface height as the surface height difference; In step S4, the process of determining whether the diamond dust spreading effect meets the preset standard is as follows: Comparing the surface height difference with a preset surface height difference threshold; If the surface height difference is greater than the surface height difference threshold, it is determined that the diamond dust spreading effect does not meet the preset standard; Step S5, controlling the trowel to repeatedly smooth the characteristic dominant sub-regions where the corundum spreading effect does not meet the preset standard, and performing secondary spreading and smoothing of corundum on each characteristic dominant sub-region that has been smoothed;
