[0024] According to the temperature measurement method of the mass concrete pouring process of the embodiment of the present invention, a laser thermometer is used to directly irradiate the thin solid bottom of the metal pipe, so that more accurate central temperature data can be obtained, thereby improving the monitoring accuracy of the internal temperature of the mass concrete. Through the non-contact characteristics of the laser thermometer, the central temperature data can be obtained in real time without interfering with the concrete pouring process, thereby improving the efficiency and safety of the construction process. Through the metal pipe and the laser thermometer, the temperature measurement process is simplified, and it is not easy to be damaged, thereby reducing the temperature measurement cost. Through the comprehensive analysis of the internal temperature score and the internal and external temperature difference score, the temperature change of the mass concrete can be comprehensively evaluated, thereby determining the temperature measurement result.

[0025] According to one embodiment of the present invention, in step S101, Figure 2The schematic diagram of the metal tube arrangement according to an embodiment of the present invention is shown as an example. Before the mass concrete pouring operation begins, multiple metal tubes need to be uniformly welded to the vertical steel bars in the mass concrete template in the depth direction and length direction of the mass concrete template, wherein the inner diameter of the metal tube can be set to 1 cm, 2 cm, etc., and the tube wall thickness of the metal tube can be set to 0.2 cm, 0.4 cm, etc., which is not limited by the present invention. The length of the metal tube is set to half the width of the mass concrete template, and the placement direction is parallel to the width direction of the mass concrete template. One end of each metal tube is designed as a thin solid bottom, and the thin solid bottom is precisely set at the center position of the width of the mass concrete template, wherein the thickness of the thin solid bottom can be set to 0.1 cm, 0.2 cm, etc., which is not limited by the present invention. The other end of the metal tube is installed as a piston, and all pistons are set on the same side of the mass concrete template. The setting of the thin solid bottom and the piston can prevent concrete or other impurities from entering the metal tube during the mass concrete pouring process, thereby improving the accuracy of temperature measurement. Obtain and record the position information of the thin solid bottom of the metal tube in the large-volume concrete formwork. The position information includes three aspects: first, the coordinates of the thin solid bottom of the metal tube in the length direction of the large-volume concrete formwork, second, the coordinates of the thin solid bottom of the metal tube in the width direction of the large-volume concrete formwork, and third, the coordinates of the thin solid bottom of the metal tube in the depth direction of the large-volume concrete formwork.

[0026] According to one embodiment of the present invention, in step S102, each temperature measurement cycle can be set to 1 hour, 2 hours, etc., and the interval between adjacent moments can be set to 10 minutes, 15 minutes, etc., which is not limited by the present invention. When the mass concrete pouring is completed, the piston of each metal pipe is removed, and a laser thermometer is used to measure the thin solid bottom of the metal pipe. The laser thermometer is a non-contact temperature measurement tool that can accurately obtain the temperature of the target object.

[0027] According to an embodiment of the present invention, in step S103, an internal temperature score is determined based on the core temperature data and the location information.

[0028] According to one embodiment of the present invention, step S103 includes: calculating the standard deviation of the central temperature data at the i-th moment of the current temperature measurement period to obtain the central temperature standard deviation data at the i-th moment of the current temperature measurement period, wherein i is a positive integer; determining the internal temperature distribution coefficient of the mass concrete at the i-th moment of the current temperature measurement period according to the central temperature data at the i-th moment of the current temperature measurement period, the position information and the central temperature standard deviation data at the i-th moment of the current temperature measurement period; determining the internal temperature variation coefficient of the mass concrete according to the central temperature data at multiple moments of the current temperature measurement period and the position information; averaging the internal temperature distribution coefficients of the mass concrete at multiple moments of the current temperature measurement period and performing weighted summation with the result of subtracting the internal temperature variation coefficient from 1 to determine the internal temperature score.

[0029] According to one embodiment of the present invention, the center temperature standard deviation data reflects the degree of fluctuation of the center temperature data, and can quantify the temperature distribution at the i-th moment of the current temperature measurement cycle. The internal temperature distribution coefficient is used to evaluate the distribution of the internal temperature of the mass concrete at the i-th moment of the current temperature measurement cycle. The internal temperature variation coefficient is used to evaluate the degree of variation of the internal temperature of the mass concrete. The internal temperature distribution coefficients of the mass concrete at multiple moments in the current temperature measurement cycle are averaged to obtain an average value. The average value is weighted and summed with the result of 1 minus the internal temperature variation coefficient to determine the internal temperature score. The internal temperature score comprehensively considers the normality and variation of the internal temperature of the mass concrete. The larger the internal temperature score, the more normal the distribution of the internal temperature of the mass concrete and the smaller the variation of the internal temperature, that is, the internal temperature condition of the mass concrete is good.

[0030] According to one embodiment of the present invention, the internal temperature distribution coefficient of the mass concrete at the i-th moment in the current temperature measurement period is determined according to the central temperature data at the i-th moment in the current temperature measurement period, the position information and the central temperature standard deviation data at the i-th moment in the current temperature measurement period, including: determining the internal temperature distribution coefficient of the mass concrete at the i-th moment in the current temperature measurement period according to formulas (1), (2), (3), (4) and (5): ,

[0037] According to one embodiment of the present invention, in formula (1), Indicates that the difference between the temperature value of the thin solid bottom of the nth metal tube in the depth direction and the m+1th metal tube in the length direction of the large volume concrete formwork at the i-th moment in the current temperature measurement period and the temperature value of the thin solid bottom of the nth metal tube in the depth direction and the mth metal tube in the length direction of the large volume concrete formwork at the i-th moment in the current temperature measurement period is When the conditional function value is 1, it means that the temperature difference at the thin bottom of the adjacent metal tubes in the length direction of the mass concrete formwork is normal. Otherwise, the conditional function value is 0, which means that the temperature difference at the thin bottom of the adjacent metal tubes in the length direction of the mass concrete formwork is abnormal. In formula (3), It means that when the temperature value of the thin solid bottom of the nth metal tube in the depth direction and the m+1th metal tube in the length direction of the large volume concrete formwork at the i-th moment of the current temperature measurement period and the temperature value of the thin solid bottom of the nth metal tube in the depth direction and the mth metal tube in the length direction of the large volume concrete formwork at the i-th moment of the current temperature measurement period are both less than the preset temperature value, the conditional function value is 1, otherwise, the conditional function value is 0. In formula (5), It represents the temperature at the thin solid bottom of adjacent metal tubes in the length direction of the mass concrete formwork, as well as the temperature difference. The corresponding piecewise function values ​​are averaged to indicate the normality of the temperature distribution of the mass concrete in the length direction. The larger the average value, the more normal the temperature distribution of the mass concrete in the length direction.

[0038] According to one embodiment of the present invention, in formula (2), It indicates that the difference between the temperature value of the thin solid bottom of the mth metal tube in the depth direction of the large volume concrete formwork and the temperature value of the thin solid bottom of the nth metal tube in the length direction and the mth metal tube in the depth direction of the large volume concrete formwork and the length direction at the i-th moment of the current temperature measurement period is When the conditional function value is 1, it means that the temperature difference at the thin bottom of the adjacent metal tubes in the depth direction of the mass concrete formwork is normal. Otherwise, the conditional function value is 0, which means that the temperature difference at the thin bottom of the adjacent metal tubes in the depth direction of the mass concrete formwork is abnormal. In formula (4), It means that when the temperature value of the thin solid bottom of the mth metal tube in the depth direction of the large-volume concrete formwork and the temperature value of the thin solid bottom of the nth metal tube in the depth direction and the mth metal tube in the length direction of the large-volume concrete formwork at the i-th moment of the current temperature measurement period is less than the preset temperature value, the conditional function value is 1, otherwise, the conditional function value is 0. In formula (5), It represents the temperature at the thin solid bottom of adjacent metal tubes in the depth direction of the mass concrete formwork, as well as the temperature difference. The corresponding piecewise function values ​​are averaged to indicate the normality of the temperature distribution of the mass concrete in the depth direction. The larger the average value, the more normal the temperature distribution of the mass concrete in the depth direction.

[0039] According to one embodiment of the present invention, the normality of the temperature distribution of the mass concrete in the length direction and the normality of the temperature distribution of the mass concrete in the depth direction are weighted and summed to obtain the internal temperature distribution coefficient of the mass concrete at the i-th moment in the current temperature measurement period. The larger the internal temperature distribution coefficient is, the more normal the internal temperature distribution of the mass concrete at the i-th moment in the current temperature measurement period is.

[0040] In this way, the internal temperature distribution coefficient of the mass concrete at the i-th moment in the current temperature measurement period can be determined based on the normal degree of temperature distribution of the mass concrete in the length direction and the normal degree of temperature distribution of the mass concrete in the depth direction. The internal temperature distribution status of the mass concrete at the i-th moment in the current temperature measurement period can be comprehensively monitored, thereby reducing the quality problems of the mass concrete caused by abnormal temperature distribution and improving the comprehensiveness, accuracy and objectivity of the internal temperature distribution coefficient.

[0041] According to an embodiment of the present invention, the internal temperature variation coefficient of the mass concrete is determined based on the central temperature data at multiple moments in the current temperature measurement period and the position information, including: determining the internal temperature variation coefficient of the mass concrete according to formula (6): ,

[0044] According to one embodiment of the present invention, in formula (6), It is the difference between the temperature value at the thin solid bottom of the nth metal tube in the depth direction and the mth metal tube in the length direction of the large volume concrete formwork at the i+1th moment in the current temperature measurement period, and the temperature value at the thin solid bottom of the nth metal tube in the depth direction and the mth metal tube in the length direction of the large volume concrete formwork at the i-th moment in the current temperature measurement period, and the ratio of the time interval between adjacent moments, that is, the temperature change rate between the i+1th moment and the i-th moment in the current temperature measurement period. The greater the temperature change rate, the greater the degree of change in the internal temperature of the large volume concrete. It is the relative difference between the temperature change rate between the i+1th moment and the ith moment in the current temperature measurement period and the preset temperature change rate. The larger the relative difference, the greater the internal temperature change of the mass concrete. The above relative differences are averaged to obtain the internal temperature change coefficient of the mass concrete. The larger the internal temperature change coefficient of the mass concrete, the greater the internal temperature change of the mass concrete. Conversely, the smaller the internal temperature change coefficient of the mass concrete, the smaller the internal temperature change of the mass concrete.

[0045] In this way, the internal temperature variation coefficient of the mass concrete can be determined based on the relative difference between the temperature change rate between adjacent moments and the preset temperature change rate, which reflects the change of the internal temperature of the mass concrete over time. The abnormal temperature change inside the mass concrete can be discovered in time, so that corresponding measures can be taken, which helps to better understand the thermal properties of the mass concrete.

[0046] According to one embodiment of the present invention, in step S104, on the surface of the mass concrete structure, an infrared thermometer, a thermocouple or other suitable temperature measuring equipment can be used to select a plurality of sampling points at different positions for measurement to obtain surface temperature data of each sampling point, wherein the sampling points are evenly distributed. At the same time, the ambient temperature data at the same time is obtained, and the ambient temperature data refers to the ambient temperature at the mass concrete pouring site.

[0047] According to an embodiment of the present invention, in step S105, the internal and external temperature difference score is determined according to the ambient temperature data, the surface temperature data and the core temperature data.

[0048] According to one embodiment of the present invention, step S105 includes: determining a suitable ambient temperature range for pouring mass concrete; averaging the surface temperature data of multiple sampling points on the surface of the mass concrete to obtain average surface temperature data at multiple moments in the current temperature measurement period; and determining an internal and external temperature difference score based on the suitable ambient temperature range, the average surface temperature data, the ambient temperature data, and the center temperature data.

[0049] According to one embodiment of the present invention, the suitable ambient temperature range for mass concrete pouring is generally set based on engineering standards, best practices and concrete performance requirements, so that the concrete can achieve the expected strength and durability during the pouring process. For example, the suitable ambient temperature range for mass concrete pouring is 18°C ​​to 28°C.

[0050] According to one embodiment of the present invention, the internal and external temperature difference score is determined according to the suitable ambient temperature range, the average surface temperature data, the ambient temperature data and the core temperature data, including: determining the internal and external temperature difference score according to formulas (7), (8) and (9): ,

[0051] (7),

[0052] (8),

[0053] (9),

[0054] in, is the ambient temperature data at the i-th moment of the current temperature measurement cycle, For the suitable ambient temperature range, The lowest suitable ambient temperature is The highest suitable ambient temperature is is a piecewise function for judging the ambient temperature data at the i-th moment in the current temperature measurement period, is the jth center temperature data at the i-th moment in the current temperature measurement cycle, is the average surface temperature data at the i-th moment in the current temperature measurement period, To suit the temperature difference between the inner and outer surfaces, is the minimum suitable internal and external temperature difference, For the highest suitable internal and external temperature difference, It is a piecewise function for judging the difference between the maximum value of multiple core temperature data at the i-th moment of the current temperature measurement period and the average surface temperature data at the i-th moment of the current temperature measurement period. and is the preset weight, M is the number of metal tubes in the length direction of the mass concrete formwork, N is the number of metal tubes in the depth direction of the mass concrete formwork, is the number of core temperature data at the i-th moment in the current temperature measurement cycle, is the number of moments in the temperature measurement cycle, i≤ , j≤ , and i, , j, M and N are all positive integers.

[0055] According to one embodiment of the present invention, in formula (7), Indicates that when the ambient temperature data at the i-th moment of the current temperature measurement period is within the appropriate ambient temperature range, the conditional function value is 0; otherwise, the conditional function value is . It is the relative difference between the ambient temperature data at the i-th moment in the current temperature measurement period and the lowest suitable ambient temperature. The larger the relative difference, the greater the degree to which the ambient temperature data deviates from the lowest suitable ambient temperature. It is the relative difference between the ambient temperature data at the i-th moment in the current temperature measurement period and the highest suitable ambient temperature. The larger the relative difference, the greater the degree to which the ambient temperature data deviates from the highest suitable ambient temperature. It means taking the maximum value of the above two relative differences. The larger the maximum value, the greater the degree to which the ambient temperature data deviates from the suitable ambient temperature range, the worse the suitability of the ambient temperature data, and the less suitable it is for pouring large-volume concrete. In formula (8), Indicates that when the maximum value of multiple center temperature data at the i-th moment of the current temperature measurement period and the difference between the average surface temperature data at the i-th moment of the current temperature measurement period are within the appropriate internal and external temperature difference range, the conditional function value is 0; otherwise, the conditional function value is . is the relative difference between the maximum value of multiple center temperature data at the i-th moment of the current temperature measurement period and the average surface temperature data at the i-th moment of the current temperature measurement period. The larger the relative difference, the greater the internal and external temperature difference of the mass concrete, and the more likely the mass concrete will crack. In formula (9), the above and By taking a weighted average, we can get the internal and external temperature difference score. The larger the internal and external temperature difference score is, the worse the suitability of the ambient temperature data is and the larger the internal and external temperature difference of the mass concrete is, that is, the larger the internal and external temperature difference of the mass concrete is.

[0056] In this way, the internal and external temperature difference score can be determined through the suitable ambient temperature range, average surface temperature data, ambient temperature data and core temperature data. From the two aspects of the suitability of the ambient temperature data and the degree of the internal and surface temperature difference of the large-volume concrete, temperature anomalies can be identified from the inside to the outside, reducing the occurrence of defects such as cracks, which helps to improve the quality of large-volume concrete.

[0057] According to an embodiment of the present invention, in step S106, the temperature measurement result is determined according to the internal temperature score and the internal and external temperature difference score.

[0058] According to one embodiment of the present invention, step S106 includes: if the internal temperature score is greater than or equal to the set internal temperature score threshold, and the internal and external temperature difference score is less than the set internal and external temperature difference score threshold, determining that the temperature measurement result of the mass concrete in the current temperature measurement cycle is good; if the internal temperature score is greater than or equal to the set internal temperature score threshold, and the internal and external temperature difference score is greater than or equal to the set internal and external temperature difference score threshold, determining that the temperature measurement result of the mass concrete in the current temperature measurement cycle is good; if the internal temperature score is less than the set internal temperature score threshold, and the internal and external temperature difference score is less than the set internal and external temperature difference score threshold, determining that the temperature measurement result of the mass concrete in the current temperature measurement cycle is poor; if the internal temperature score is less than the set internal temperature score threshold, and the internal and external temperature difference score is greater than or equal to the set internal and external temperature difference score threshold, determining that the temperature measurement result of the mass concrete in the current temperature measurement cycle is poor.

[0059] According to one embodiment of the present invention, when the temperature measurement result is good, it means that the temperature condition of the bulk concrete in the current temperature measurement cycle is good and no operation is required. When the temperature measurement result is good, it means that the internal temperature condition of the bulk concrete in the current temperature measurement cycle is good, the temperature difference between the inside and outside is large, and the bulk concrete needs to be kept warm or cooled. For example, when the ambient temperature data exceeds the suitable ambient temperature range, a cooling operation is performed, and water with a lower temperature is used for spraying and cooling. When the ambient temperature data is lower than the suitable ambient temperature range, a heat preservation operation is performed, and plastic film, straw mat, quilt, etc. are used for covering and insulation. When the temperature measurement result is poor, it means that the internal temperature condition of the bulk concrete in the current temperature measurement cycle is not good, and the temperature difference between the inside and outside is small. It is necessary to use the buried cooling water pipe to cool the inside of the bulk concrete, adjust the internal temperature, and reduce potential problems caused by excessive temperature. When the temperature measurement result is poor, it means that the internal temperature condition of the bulk concrete in the current temperature measurement cycle is not good, and the temperature difference between the inside and outside is large. It is necessary to keep warm or cool the outside of the bulk concrete and use the buried cooling water pipe to cool the inside of the bulk concrete.

[0060] According to the temperature measurement method of the mass concrete pouring process of the embodiment of the present invention, a laser thermometer is used to directly irradiate the thin solid bottom of the metal pipe, so that more accurate central temperature data can be obtained, thereby improving the monitoring accuracy of the internal temperature of the mass concrete. Through the non-contact characteristics of the laser thermometer, the central temperature data can be obtained in real time without interfering with the concrete pouring process, thereby improving the efficiency and safety of the construction process. Through the metal pipe and the laser thermometer, the temperature measurement process is simplified, and it is not easy to be damaged, thereby reducing the temperature measurement cost. Through the comprehensive analysis of the internal temperature score and the internal and external temperature difference score, the temperature change of the mass concrete can be comprehensively evaluated to determine the temperature measurement result. When determining the internal temperature distribution coefficient of the mass concrete, the internal temperature distribution coefficient of the mass concrete at the i-th moment of the current temperature measurement cycle can be determined based on the normal degree of the temperature distribution of the mass concrete in the length direction and the normal degree of the temperature distribution of the mass concrete in the depth direction. The internal temperature distribution status of the mass concrete at the i-th moment of the current temperature measurement cycle can be comprehensively monitored, reducing the quality problems of the mass concrete caused by abnormal temperature distribution, and improving the comprehensiveness, accuracy and objectivity of the internal temperature distribution coefficient. When determining the internal temperature variation coefficient of mass concrete, the internal temperature variation coefficient of mass concrete can be determined based on the relative difference between the temperature variation rate between adjacent moments and the preset temperature variation rate, which reflects the change of the internal temperature of mass concrete over time, and can timely discover the temperature variation anomaly inside the mass concrete, so as to take corresponding measures, which is helpful to better understand the thermal properties of mass concrete. When determining the internal and external temperature difference score, the internal and external temperature difference score can be determined by the suitable ambient temperature range, average surface temperature data, ambient temperature data and core temperature data. From the two aspects of the suitability of ambient temperature data and the degree of internal and external temperature difference of mass concrete, temperature anomalies can be identified from the inside to the outside, reducing the occurrence of defects such as cracks, which helps to improve the quality of mass concrete.
