Description

Technical Field

[0001] The present invention relates to the technical field of casting quality monitoring, and particularly to a real-time monitoring method for the casting quality of concrete in building construction. Background Art

[0002] Concrete is the most commonly used and important structural material in modern construction projects, and its casting quality directly affects the strength, durability, and safety of the project. On construction sites, workers generally judge the casting height and flatness based on experience, supplemented by simple steel tapes or wooden rulers for spot checks; the vibration operation is also mostly controlled by the "feel" of the vibration workers to control the insertion depth and vibration duration of the vibrator. Due to the lack of quantitative standards and real-time feedback, local over-vibration or under-vibration is likely to occur, resulting in quality defects such as honeycombing, pockmarks, and segregation.

[0003] Specifically in the casting of wall-column concrete, due to the long and narrow cross-section and great difficulty in vibration, it is usually necessary to use internal vibrators for layered vibration to ensure that the concrete is uniform and dense in a narrow space. However, the traditional on-site vibration method mostly relies on the experience of workers, lacking real-time monitoring and quantitative evaluation of the insertion depth and vibration quality of the vibrator, and it is easy to have the quality risks of over-vibrating and damaging the formwork or insufficient insertion resulting in poor compaction, thus affecting the overall load-bearing performance of the wall-column and the subsequent non-compliance of the building quality. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a real-time monitoring method for the casting quality of concrete in building construction, which solves the problems in the background art.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A real-time monitoring method for the casting quality of concrete in building construction, including: Step 1: Through the setting of the concrete layer height, during the concrete casting, the height of the concrete cast at different positions in the casting space is monitored and analyzed in real time to determine the casting reference height, and it is judged whether the concrete casting layer height meets the standard according to the casting reference height; Step 2: When the concrete casting layer height meets the standard, during the vibration of the vibrator, it is monitored in real time whether the vibration position of the vibrator is reasonable; Step 3: Then, obtain the surface vibration image of the vibrator, determine the vibration radius according to the vibrator specifications, combine the vibration radius to determine the vibration action area in the surface vibration image and analyze it, and judge in real time whether the vibration action area is vibrated qualified. When it is judged as vibrated qualified three times in a row, the vibration ends; Specifically including: CS1: Obtain the surface vibration image of the vibrator through an industrial camera; CS2: Then determine the position of the vibrator in the surface vibration image, and with this position as the center and the vibration radius determined according to the vibrator specifications, confirm the vibration action area in the surface vibration image; CS3: Intercept the vibration scope in the surface vibration image, perform image preprocessing, and monitor the number of bubbles and the area occupied by bubbles in the vibration scope of the surface vibration image through a preset bubble monitoring model; CS4: Judge whether the vibration scope is qualified according to the number of bubbles and the area occupied by bubbles: If the number of bubbles is less than the preset value Q2 and the area occupied by bubbles is less than the preset value Sq, it is judged that the vibration scope is qualified; in other cases, it is judged that the vibration scope is unqualified; CS5: Repeat CS1 - CS4. If it is judged that the vibration scope is qualified three times in a row, stop the vibration; in other cases, do nothing; Step Four: After stopping the vibration, pull out the vibrator and move it above the concrete within a distance not exceeding twice the vibration radius, insert it into the concrete again for vibration, repeat the process of Step Two and Step Three, and monitor in real time whether the vibration position of the vibrator is reasonable and judge in real time whether the vibration scope is qualified. When it is judged to be qualified three times in a row, stop the vibration; and so on until the layered vibration of the concrete is completed; Step Five: Repeat Step One to Step Four to perform real-time monitoring on each layer of the poured concrete.

[0006] As a further solution of the present invention: In the above Step One, the pouring space is a load-bearing and structural part of a building structure.

[0007] As a further solution of the present invention: The specific method for real-time monitoring and analyzing the pouring height of concrete at different positions in the pouring space to determine the pouring reference height is as follows: AS1: Obtain the concrete height at different positions during pouring; at the same time, determine the maximum and minimum values of the currently poured concrete, calculate the difference between the two as the concrete pouring difference value, and denote it as Hc; AS2: Obtain Hc, and determine the specific position of the pouring point, obtain the horizontal distance between the positions of different height measuring sensors and the pouring point, and denote it as , where 1 ≤ i ≤ n, and n represents the total number of positions of the height measuring sensors; The pouring point is the position where concrete is discharged through a chute string; Then, combine Li and the original concrete heights Di at different positions to perform height compensation on the positions of different height measuring sensors through a preset formula, and denote it as Gi; AS3: Obtain the compensated height Gi, calculate the average value of the n compensated heights , and denote it as Gp; then calculate the standard deviation Z of the corresponding n compensated heights through the standard deviation formula; AS4: Obtain the standard deviation Z and compare it with the preset value Q1: If the standard deviation Z does not exceed the preset value Q1, it means that the standard deviation is within a reasonable range; Gp is used to determine the pouring reference height; If the standard deviation Z exceeds the preset value Q1, it means that the standard deviation is too large, and the data of n compensation heights Gi are eliminated, and the casting reference height is determined based on the results of data elimination.

[0008] As a further solution of the present invention: the specific method of determining the pouring reference height according to the result of data elimination is: Calculate the result of |Gi-Gp|, sort Gi from large to small, remove the first ranked Gi each time, recalculate the standard deviation Z of the remaining Gi, and compare it with the preset value Q1 again, and so on, until the standard deviation Z does not exceed the preset value Q1; Then count the number of eliminated data and record it as g1, and determine the pouring base height through the following judgment: If g1>n / 2, the average value of the excluded data is calculated as the pouring reference height; If g1≤n / 2, the average value of the uneliminated data is calculated as the pouring reference height.

[0009] As a further solution of the present invention: the specific method of judging whether the concrete pouring layer height meets the standard according to the pouring reference height is: The pouring reference height is obtained and compared with the concrete layer setting height. When the pouring reference height is the same as the concrete layer setting height, it means that the concrete pouring layer height meets the standard and the concrete pouring is stopped.

[0010] As a further solution of the present invention: in the step 2, the specific method of real-time monitoring whether the vibration position of the vibrator is reasonable is: Obtain the concrete layer setting height and the insertion depth in the next layer of concrete, calculate the sum of the two, and obtain the minimum reaching depth of the vibrator; During the process of inserting the vibrator into the concrete, the insertion depth of the vibrator is monitored in real time. When the insertion depth exceeds the minimum reaching depth of the vibrator, it means that the vibration position of the vibrator is reasonable, and the insertion is stopped, and the insertion depth of the vibrator in the working state continues to be monitored.

[0011] As a further solution of the present invention: the vibration action domain represents an image area in the surface vibration image that is a circle with the position of the vibrator as the center and the vibration radius as the center.

[0012] The present invention provides a method for real-time monitoring of concrete pouring quality in building construction. Compared with the prior art, it has the following beneficial effects: Through the arrangement of various sensing and visual monitoring means, the present invention realizes the all-round real-time acquisition and dynamic feedback from the layered height, vibration insertion depth to the surface bubble state, forming structured and quality-based quality control indicators; it can timely detect and correct deviations during the construction process, avoid the risks of honeycombing, surface pitting, structural defects and formwork and reinforcement damage caused by insufficient vibration or excessive operation, significantly improve the concrete density, consistency and surface quality, and at the same time ensure construction safety and efficiency.

[0013] In multi-layer pouring, this method applies the above monitoring and judgment process in a cycle, constructs a traceable closed-loop quality management system, and enables each pouring layer to be carried out under strict control. With the real-time warning and data recording mechanism, it not only simplifies the acceptance process but also reduces the rework and maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Figure 1 is a step flow chart of a method for real-time monitoring of the quality of concrete pouring in building construction according to the present invention; DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] Example 1, please refer to Figure 1 , the present invention provides a method for real-time monitoring of the quality of concrete pouring in building construction, including; Step 1: Through the setting of the concrete layered height, during the concrete pouring, the height of the concrete poured at different positions in the pouring space is monitored and analyzed in real time, the pouring reference height is determined, and whether the concrete pouring layered height meets the standard is judged according to the pouring reference height; The pouring space is a load-bearing and structural part for building structures, including spatial structures such as walls (shear walls, load-bearing walls), independent foundations, column bases, etc.; It should be noted that the concrete needs to be poured in layers and sections during pouring, and the layered height is generally 1.25 times the effective action length of the vibrator. During the pouring process, when the concrete pouring height of a general layer is greater than 2 meters, a chute or a string tube should be used for feeding to prevent the segregation and layering of the concrete; Install height measurement sensors at different positions in the pouring space. The number and positions of the installed height measurement sensors are determined by professional staff. Specific height measurement sensors include: industrial ultrasonic distance measurement sensors, laser (optical) distance measurement sensors, etc., which are specifically determined by professional staff according to the site conditions; The specific method for real-time monitoring and analyzing the pouring height of concrete at different positions in the pouring space and determining the pouring reference height is as follows: AS1: Obtain the concrete heights at different positions during pouring; simultaneously determine the maximum and minimum values of the current concrete pouring, calculate the difference between the two as the concrete pouring difference value, and denote it as Hc; It should be noted that during concrete pouring, the concrete at the pouring point is generally fed through a chute string. The maximum value of the concrete pouring is at the pouring point, and the position farthest from the pouring point is the minimum value of the concrete pouring; AS2: Obtain Hc, and determine the specific position of the pouring point, obtain the horizontal distances between the positions of different height measurement sensors and the pouring point, and denote them as , where 1 ≤ i ≤ n, and n represents the total number of positions of the height measurement sensors; The pouring point is the position where concrete is fed through a chute string; Then, perform height compensation on the positions of different height measurement sensors through the following formula: ; Among them, represents the compensated height after position compensation of different height measurement sensors, is the weight coefficient, which is specifically determined by professional staff, represents the original concrete heights at different positions; AS3: Obtain the compensated height , and calculate the average value of the n compensated heights and denote it as Gp; then calculate the standard deviation Z of the corresponding n compensated heights through the standard deviation formula; AS4: Obtain the standard deviation Z and compare it with the preset value Q1: If the standard deviation Z does not exceed the preset value Q1, it means that the standard deviation is within a reasonable range; determine Gp as the pouring reference height; If the standard deviation Z exceeds the preset value Q1, it means that the standard deviation is too large, and data elimination is performed on the n compensated heights as follows: Calculate the result of |Gi - Gp|, sort Gi in descending order, each time obtain the Gi ranked first for elimination, and recalculate the standard deviation Z of the remaining Gi, and compare it with the preset value Q1 again. Repeat the above steps until the standard deviation Z does not exceed the preset value Q1; Then count the number of eliminated data and record it as g1, and determine the pouring reference height through the following judgment: If g1 > n / 2, then calculate the average value of the eliminated data as the pouring reference height; If g1 ≤ n / 2, then calculate the average value of the uneliminated data as the pouring reference height; It should be noted that during the pouring process, when pouring stops, the concrete at different positions will no longer flow after a period of advection, and at this time, the heights of the concrete at different positions are not the same. By real-time monitoring and analyzing the pouring heights of the concrete at different positions in the pouring space, the process of determining the pouring reference height can more accurately reflect the representative height during the current concrete pouring; The specific method for judging whether the concrete pouring layer height meets the standard according to the pouring reference height is as follows: Obtain the pouring reference height and compare it with the set height of the concrete layer. When the pouring reference height is the same as the set height of the concrete layer, it means that the concrete pouring layer height meets the standard, and stop the concrete pouring; By arranging ultrasonic or laser height sensors in the concrete pouring area, the height data of each point of the layered pouring can be collected in real time, and the outliers can be corrected by using the height compensation and statistical elimination algorithm. Finally, the accurate pouring reference height can be determined; not only can the local height deviation be dynamically mastered during the pouring process, avoiding the layer height error caused by concrete segregation or insufficient surface flatness, ensuring that each layer of concrete can strictly meet the design elevation requirements, and improving the overall flatness of the structure; Step 2: When the concrete pouring layer height meets the standard, during the vibration process, real-time monitor whether the vibration position of the vibrator is reasonable; It should be noted that when the vibrator vibrates, the depth that the vibrator should insert into the next layer of concrete should not be less than 50 mm; The specific method for real-time monitoring whether the vibration position of the vibrator is reasonable is as follows: BS1: Obtain the set height of the concrete layer and the insertion depth into the next layer of concrete, calculate the sum of the two to obtain the lowest arrival depth of the vibrator; BS2: During the process of the vibrator inserting into the concrete, real-time monitor the insertion depth of the vibrator. When the insertion depth exceeds the lowest arrival depth of the vibrator, it means that the vibration position of the vibrator is reasonable, stop inserting, and continue to monitor the insertion depth of the vibrator during the working state to prevent the vibrator from reaching above the lowest arrival depth of the vibrator; It should be noted that when monitoring the insertion depth of the vibrator (inserted vibrator rod) in concrete on site, the common solution is to install a displacement / angle sensor on the vibrator rod or the wire supply drum, and calculate the depth in combination with the calibration curve; specifically, the wire supply cable (or special steel wire rope) of the vibrator is wound on a drum / pulley with an encoder; the encoder measures the length of the cable for each turn, and the total length pulled out or retracted can be calculated by accumulating the number of turns and pulses; measurement principle: incremental photoelectric / magnetic encoder: detects the pulses of the drum rotation, knows the cable length corresponding to each pulse (drum circumference ÷ pulse number), and accumulates it; absolute encoder: even if the power is off, the current angle can be known, which is suitable for long-term construction monitoring; During the vibration process, the insertion depth of the vibrator is monitored in real time through a cable drum encoder or a displacement / angle sensor in combination with the preset layer height target, which prevents insufficient compaction caused by insufficient insertion of the vibrator, thereby promoting a more uniform rearrangement of the particles inside the concrete, thereby improving the density and later mechanical properties of the concrete; Step 3: During the vibration process of the vibrator, a surface vibration image of the vibrator is obtained, the vibration radius is determined according to the specifications of the vibrator, the vibration scope in the surface vibration image is determined in combination with the vibration radius and analyzed, and it is judged in real time whether the vibration scope is qualified. When it is judged to be qualified for three consecutive times, the vibration is terminated; The surface vibration image of the vibrator is obtained, the vibration radius is determined according to the specifications of the vibrator, the vibration scope in the surface vibration image is determined in combination with the vibration radius and analyzed, and it is judged in real time whether the vibration scope is qualified. When it is judged that the vibration is qualified for three consecutive times, the specific content of ending the vibration is: CS1: The surface vibration image of the vibrator is obtained through an industrial camera. Specifically, a small industrial camera is installed on the vibrator along the vibration radius, with the lens pointing to the concrete vibration surface. At the same time, a ring-shaped adjustable brightness LED is used to ensure that the surface cement slurry reflects evenly and the shadow is minimized. CS2: Then determine the position of the vibrator in the surface vibration image, take the position as the center of the circle, and determine the vibration radius based on the vibrator specifications to confirm the vibration range in the surface vibration image; Specifically, the vibration scope represents an image area in the surface vibration image that is a circle with the position of the vibrator as the center and the vibration radius as the center; CS3: intercept the vibration scope in the surface vibration image, perform image preprocessing, and monitor the number of bubbles and the area occupied by bubbles in the surface vibration image scope through the preset bubble monitoring model; In the training process of the preset bubble monitoring model, first, multi-scene videos are collected at the actual vibration site and the bubble masks are accurately labeled. Subsequently, the data is subjected to ROI cropping, normalization, and various online augmentations. Then, a lightweight instance segmentation network (such as YOLOX-S + SegHead or MobileNetV3 + DeepLabV3) is selected and fine-tuned with a mixed loss of detection and segmentation. Next, the optimal model is selected through the mAP, mIoU, and Precision / Recall of the validation set. Finally, the model is quantized, pruned, and tested for real-time performance, packaged into an embeddable API, and continuously adapted through online case collection and periodic fine-tuning; CS4: Determine whether the vibration scope is qualified according to the number of bubbles and the area occupied by the bubbles: If the number of bubbles is less than the preset value Q2 and the area occupied by the bubbles is less than the preset value Sq, it is determined that the vibration scope is qualified; among them, the specific preset values Q2 and Sq are determined by professional staff; in other cases, it is determined that the vibration scope is unqualified; CS5: Repeat CS1 - CS4. If it is determined that the vibration scope is qualified three times in a row, stop vibrating; in other cases, do nothing; By arranging industrial cameras and ring lights around the vibration area, the vibration surface image is intercepted in real time, and the trained instance segmentation network model is used to accurately identify and count the bubbles on the concrete surface; this scheme can quantitatively evaluate the changes in the number and area of bubbles after vibration. When the set threshold is met three times in a row, the vibration can be ended. This not only makes the vibration process have visual and quantitative feedback, but also effectively reduces surface defects such as honeycombing and pitting, significantly improves the surface quality and internal density of the concrete, and lays a solid foundation for subsequent maintenance and long-term durability; Step 4: After the vibration is completed, pull out the vibrator and move it above the concrete within a distance not exceeding twice the vibration radius, and then insert it into the concrete again for vibration. During the vibration process, repeat Step 2 and Step 3 to monitor in real time whether the vibration position of the vibrator is reasonable and judge in real time whether the vibration scope is qualified. When it is determined that the vibration is qualified three times in a row, stop vibrating; and so on until the vibration of this layer of concrete is completed; After completing the single-point vibration, the vibrator is automatically moved in segments at intervals not exceeding twice the vibration radius, and the insertion depth monitoring and bubble analysis are repeated until the entire layered area is covered; effectively eliminating the problem of uneven local compaction caused by vibration dead spots during construction, ensuring that the entire layer of concrete can achieve the same compaction effect at each position, thus improving the overall uniformity and structural coherence during large-area pouring, and reducing the risk of structural cracks caused by local looseness in the later stage.

[0018] Example 2. In the specific implementation process of this example, based on Example 1 and different from Example 1, this example further includes: Step 5: Repeat Steps 1 to 4 to perform real-time monitoring on each layer of the poured concrete to ensure the integrity of the pouring process; The monitoring and judgment processes of Steps 1 to 4 are cyclically executed in each layer-by-layer pouring, forming a closed-loop real-time monitoring system from height monitoring, insertion depth control to bubble quality assessment; this full-process monitoring not only provides traceable data records for the multi-layer pouring process, but also can timely detect and correct potential deviations between each layer, realizing the quality control and management of the whole process.

[0020] Some of the data in the above formula are numerically calculated after removing their dimensions, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0021] The above examples are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
