Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated component safety monitoring, and in particular to a visual analysis system for prefabricated component building construction safety. Background Art

[0002] Construction safety is of vital importance in prefabricated building construction. Traditional construction safety monitoring methods often have certain limitations. For example, manual inspections are inefficient and highly subjective, making it difficult to comprehensively and promptly detect potential safety hazards. With the development of computer vision and data analysis technologies, the use of visual analysis systems to monitor the safety of prefabricated building construction has become a feasible and effective method. By collecting relevant images and data of the construction area and analyzing them using advanced algorithms and models, risks in construction can be more accurately identified, such as unstable supports and position deviations of prefabricated components. This allows for timely implementation of appropriate measures to ensure construction safety and improve construction quality and efficiency. This is the background for the development of this visual analysis system for prefabricated building construction safety.

[0003] For example, Chinese patent application publication number: CN116332023A discloses a safety leveling device for prefabricated component transfer, which specifically relates to the field of prefabricated component transfer technology. The invention can smoothly hook the prefabricated component by extending the adjustable suspension structure, and multiple lifting structures are connected to multiple points of the prefabricated component. At this time, the spirit level is used to observe whether the circular shell remains horizontal, thereby avoiding the dangerous problem of the prefabricated component tilting during lifting. Secondly, the adjustable suspension structure can play a tightening role, thereby maintaining the balance of multiple force points, avoiding the troublesome operation of the staff to adjust again, thereby achieving the effect of automatic leveling, and the adjustable suspension structure can adaptively extend to meet the size and length of different prefabricated components, facilitating the suspension operation. Secondly, during the suspension process through the elastic suspension structure, the rotating locking structure and the adjustable suspension structure can be automatically engaged to complete the operation of firmly fixing the prefabricated component, thereby increasing the lifting safety and improving work efficiency.

[0004] However, existing technologies have poor accuracy in identifying risks of individual prefabricated components and associated risks, and inaccurate predictions of risk diffusion trends, which solves the problem that traditional monitoring is difficult to accurately capture risks and their chain reactions. Summary of the Invention

[0005] To this end, the present invention provides a visual analysis system for the safety of prefabricated component construction, which is used to overcome the poor accuracy of identifying individual risks and associated risks of prefabricated components in the existing technology, and the inaccurate prediction of risk diffusion trends, thereby solving the problem that traditional monitoring is difficult to accurately capture risks and their chain reactions.

[0006] To achieve the above objectives, the present invention provides a visual analysis system for prefabricated building construction safety, comprising:

[0007] A data acquisition module is used to collect prefabricated component distribution image data, prefabricated component support image data, and prefabricated component construction progress data in the construction area;

[0008] a data analysis module connected to the data acquisition module, for determining the risk tendency type of prefabricated component construction based on the support area of the prefabricated components and the position deviation of the symmetrical support positions of the prefabricated components within the construction area;

[0009] a risk area identification module connected to the data analysis module, for determining whether there are other risky prefabricated components within the risky prefabricated component impact interval based on the prefabricated component construction risk tendency type, or determining the prefabricated component risk area based on the risky prefabricated component support sensitivity;

[0010] a diffusion analysis module connected to the risk area identification module, for determining a risk diffusion area based on the areas where prefabricated components associated with risky prefabricated components in the prefabricated component risk area are located, and whether a circular line exists between a plurality of prefabricated component risk areas that are in a positionally continuous relationship;

[0011] A risk assessment module is connected to the diffusion analysis module and is used to determine whether to enhance the support strength of risk prefabricated components in the associated risk areas of the risk diffusion area based on the area of the risk diffusion area and whether the risk diffusion area is a completed construction area, or to dynamically monitor the area change rate of the risk diffusion area.

[0012] Furthermore, the data analysis module determines the prefabricated component construction risk tendency type based on the support area of the prefabricated components in the construction area and the position deviation of the symmetrical support positions of the prefabricated components; wherein,

[0013] If the support area of the prefabricated component in the construction area is larger than the preset support area or the position deviation of the symmetrical support position of the prefabricated component is smaller than the preset position deviation, the prefabricated component construction risk tendency type is determined to be a weak risk tendency type;

[0014] If the support area of the prefabricated components in the construction area is less than or equal to the preset support area and the position deviation of the symmetrical support position of the prefabricated components is greater than or equal to the preset position deviation, the prefabricated component construction risk tendency type is determined to be a strong risk tendency type.

[0015] Furthermore, the preset position deviation is determined based on the average position deviation of several construction processes of the same type of prefabricated components without support risks, and the preset support area is determined based on the average support area of several identical prefabricated components under the same construction conditions.

[0016] Furthermore, the risk area identification module determines whether there are other risky prefabricated components within the risky prefabricated component impact interval based on the prefabricated component construction risk tendency type, or determines the prefabricated component risk area based on the risky prefabricated component support sensitivity; wherein,

[0017] If the prefabricated component construction risk tendency type is a weak risk tendency type and there are other risky prefabricated components within the risky prefabricated component impact area, the area where the risky prefabricated components are located is determined to be a risky area;

[0018] If the prefabricated component construction risk tendency type is a strong risk tendency type and the risk prefabricated component support sensitivity is greater than a preset sensitivity, the area where the risk prefabricated component is located is determined to be a risk area.

[0019] Furthermore, the support sensitivity of the risky prefabricated component is determined according to the ratio of the change in support area to the change in position deviation.

[0020] Furthermore, the diffusion analysis module determines the risk diffusion area based on the area where the risk prefabricated components are associated with the risk prefabricated components in the prefabricated component risk area and whether there is a circumferential line between several prefabricated component risk areas with a continuous position relationship; wherein,

[0021] If the area where the associated prefabricated components of the risky prefabricated components in the prefabricated component risk area are located is a non-risk area or there is a circumferential line between several prefabricated component risk areas that are in a continuous position relationship, the area is determined to be a risk diffusion area.

[0022] Furthermore, the diffusion analysis module determines that there are circular lines among several prefabricated component risk areas that are in a positional continuity relationship, including the center points of several prefabricated component risk areas that form an approximately circular distribution in space, so that the distance difference between the center point of each risk area and the center of the circle is within a preset tolerance, and the angle between the lines connecting adjacent center points meets the characteristic of equal division of the circle.

[0023] Furthermore, the risk assessment module determines whether to enhance the support strength of risk prefabricated components in the associated risk areas of the risk diffusion area based on the area of the risk diffusion area and whether the risk diffusion area is a completed construction area, or dynamically monitors the area change rate of the risk diffusion area; wherein,

[0024] If the area of the risk diffusion zone is larger than the preset area or the risk diffusion zone is a construction completed area, determine the area change rate of the dynamically monitored risk diffusion zone;

[0025] If the area of the risk diffusion zone is smaller than or equal to the area of the preset area and the risk diffusion zone is an area where construction is not completed, it is determined to enhance the support strength of the risk prefabricated components in the risk areas associated with the risk diffusion zone.

[0026] Furthermore, the dynamically monitoring the area change rate of the risk diffusion region includes dynamically monitoring the area change rate of the risk diffusion region within a preset period.

[0027] Furthermore, the enhancing the supporting strength of the risk prefabricated components in the risk area associated with the risk diffusion area includes adding temporary supporting columns or adjusting the positions of supporting points.

[0028] Compared with the prior art, the beneficial effect of the present invention lies in that the present invention determines the prefabricated component construction risk tendency type by the support area of the prefabricated components in the construction area and the position deviation of the symmetrical support position of the prefabricated components. According to the fact that the support area of the prefabricated components in the construction area is greater than the preset support area or the position deviation of the symmetrical support position of the prefabricated components is less than the preset position deviation, it indicates that the support area is sufficient and the support position is relatively accurate, and the prefabricated component construction risk tendency type is accurately determined to be a weak risk tendency type. According to the fact that the support area of the prefabricated components in the construction area is less than or equal to the preset support area or the position deviation of the symmetrical support position of the prefabricated components is greater than or equal to the preset position deviation, it indicates that the support area is insufficient or the support position deviation is large, and the prefabricated component construction risk tendency type is accurately determined to be a strong risk tendency type. The above method improves the accuracy of identifying single risks and associated risks of prefabricated components, realizes the prediction of risk diffusion trends, and accurately captures risks and their chain reactions.

[0029] Furthermore, the present invention determines whether there are other risky prefabricated components within the influence interval of the risky prefabricated component based on the risk tendency type of the prefabricated component construction, or determines the risk area of the prefabricated component based on the support sensitivity of the risky prefabricated component. According to the fact that the risk tendency type of the prefabricated component construction is a weak risk tendency type and there are other risky prefabricated components within the influence interval of the risky prefabricated component, it indicates that the risk tendency of a single prefabricated component itself is weak, but there are other risky prefabricated components within its influence range. The area where the risky prefabricated component is located is accurately determined to be a risk area. According to the fact that the risk tendency type of the prefabricated component construction is a strong risk tendency type and the support sensitivity of the risky prefabricated component is greater than the preset sensitivity, it indicates that the prefabricated component itself has a high risk tendency and the support system is more sensitive to position changes. The area where the risky prefabricated component is located is accurately determined to be a risk area. The above method improves the accuracy of identifying single risks and associated risks of prefabricated components, realizes the prediction of risk diffusion trends, and accurately captures risks and their chain reactions.

[0030] Furthermore, the present invention determines the risk diffusion area by the area where the associated prefabricated components of the risk prefabricated components in the prefabricated component risk area are located, and whether there is a circumferential line among several prefabricated component risk areas with a continuous position relationship. According to the fact that the area where the associated prefabricated components of the risk prefabricated components in the prefabricated component risk area is a non-risk area or there is a circumferential line among several prefabricated component risk areas with a continuous position relationship, it indicates that there is a possibility and regularity of risk diffusion, and the area is accurately determined to be the risk diffusion area. According to the fact that the area where the associated prefabricated components of the risk prefabricated components in the prefabricated component risk area is a risk area and there is no circumferential line among several prefabricated component risk areas with a continuous position relationship, it indicates that the risk areas are not closely connected and the possibility of diffusion is small, and the area is accurately determined not to be the risk diffusion area. The above method improves the accuracy of identifying single prefabricated component risks and associated risks, realizes the prediction of risk diffusion trends, and accurately captures risks and their chain reactions.

[0031] Furthermore, the present invention determines whether to enhance the supporting strength of risk prefabricated components in the associated risk areas of the risk diffusion area through the area of the risk diffusion area and whether the risk diffusion area is a completed construction area, or dynamically monitors the area change rate of the risk diffusion area. According to the fact that the area of the risk diffusion area is greater than the area of the preset area or the risk diffusion area is a completed construction area, it indicates that the risk diffusion range is large or the completed area is difficult to reinforce on site. The area change rate of the dynamically monitored risk diffusion area is accurately determined. According to the fact that the area of the risk diffusion area is less than or equal to the area of the preset area and the risk diffusion area is an unfinished construction area, it indicates that the risk diffusion range is controllable and is under construction. The supporting strength of risk prefabricated components in the associated risk areas of the risk diffusion area is accurately determined. The above method improves the accuracy of identifying individual risks and associated risks of prefabricated components, realizes the prediction of risk diffusion trends, and accurately captures risks and their chain reactions.

[0040] The visual analysis system for prefabricated component building construction safety according to an embodiment of the present invention includes:

[0041] A data acquisition module is used to collect prefabricated component distribution image data, prefabricated component support image data, and prefabricated component construction progress data in the construction area;

[0042] a data analysis module connected to the data acquisition module, for determining the risk tendency type of prefabricated component construction based on the support area of the prefabricated components and the position deviation of the symmetrical support positions of the prefabricated components within the construction area;

[0043] a risk area identification module connected to the data analysis module, for determining whether there are other risky prefabricated components within the risky prefabricated component impact interval based on the prefabricated component construction risk tendency type, or determining the prefabricated component risk area based on the risky prefabricated component support sensitivity;

[0044] a diffusion analysis module connected to the risk area identification module, for determining a risk diffusion area based on the areas where prefabricated components associated with risky prefabricated components in the prefabricated component risk area are located, and whether a circular line exists between a plurality of prefabricated component risk areas that are in a positionally continuous relationship;

[0045] A risk assessment module is connected to the diffusion analysis module and is used to determine whether to enhance the support strength of risk prefabricated components in the associated risk areas of the risk diffusion area based on the area of the risk diffusion area and whether the risk diffusion area is a completed construction area, or to dynamically monitor the area change rate of the risk diffusion area.

[0046] In the embodiment of the present invention, the prefabricated component distribution image data includes but is not limited to "floor plans, panoramic views and local close-up views", the prefabricated component support image data includes but is not limited to "support frame three-dimensional point cloud map, support node detail image and support system stress visualization image", and the prefabricated component construction progress data includes but is not limited to "component installation completion statistics table, construction stage progress image sequence and equipment operation status data".

[0047] Specifically, the data analysis module determines the prefabricated component construction risk tendency type based on the support area of the prefabricated components in the construction area and the position deviation of the symmetrical support positions of the prefabricated components.

[0048] If the support area of the prefabricated component in the construction area is larger than the preset support area or the position deviation of the symmetrical support position of the prefabricated component is smaller than the preset position deviation, the data analysis module determines that the prefabricated component construction risk tendency type is a weak risk tendency type;

[0049] If the support area of the prefabricated components in the construction area is less than or equal to the preset support area or the position deviation of the symmetrical support position of the prefabricated components is greater than or equal to the preset position deviation, the data analysis module determines that the prefabricated component construction risk tendency type is a strong risk tendency type.

[0050] In the embodiment of the present invention, the support area of the prefabricated components in the construction area is calculated by the coordinates of the support points. For example, the coordinates of the four support points in three-dimensional space are measured by measuring equipment, namely support point A (x1, y1, z1) = (1, 1, 0), support point B (x2, y2, z2) = (1, 5, 0), support point C (x3, y3, z3) = (5, 5, 0), support point D (x4, y4, z4) = (5, 1, 0), the length of AB LAB = (x2-x1)2 + (y2-y1)2 = (1-1)2 + (5-1)2 = 4 meters, the length of BC LBC = (x3-x2)2 + (y3-y2)2 = (5-1)2 + (5-5)2 = 4 meters, and the support area S = LAB × LBC = 4 meters × 4 meters = 16 square meters, but the above values are not limited to this, and those skilled in the art can also adjust the values according to actual needs.

[0051] In the embodiment of the present invention, the preset support area is determined according to the support plane area of the prefabricated component, and the preset support area is the average value of the support areas of several identical prefabricated components under the same construction conditions; the position deviation of the symmetrical support position of the prefabricated component is obtained by calculating the coordinates of the center point of the support position, and the preset position deviation is determined according to the average position deviation of several construction processes of the same type of prefabricated components without support risks. For example, assuming that the coordinates of support point A are (x1, y1, z1) = (2, 3, 0), and the coordinates of support point B are (x2, y2, z2) = (6, 3, 0 ), the coordinate of the center line in the x-axis direction is x0=4, the deviation of the support point A relative to the ideal center line x0 is Δx1=x1-x0=2-4=-2cm, the deviation of the support point B relative to the ideal center line x0 is Δx2=x2-x0=6-4=2cm, and the position deviation D=|Δx1|+|Δx2|=|-2cm|+|2cm|=4cm; for example, the position deviations of the same type of prefabricated components twice are 4cm and 6cm, and the preset position deviation is 5cm, but the above values are not limited to this, and those skilled in the art can also adjust the values according to actual needs.

[0052] The present invention determines the prefabricated component construction risk tendency type by the support area of the prefabricated components in the construction area and the position deviation of the symmetrical support position of the prefabricated components. According to the fact that the support area of the prefabricated components in the construction area is greater than the preset support area or the position deviation of the symmetrical support position of the prefabricated components is less than the preset position deviation, it indicates that the support area is sufficient and the support position is relatively accurate, and the prefabricated component construction risk tendency type is accurately determined to be a weak risk tendency type. According to the fact that the support area of the prefabricated components in the construction area is less than or equal to the preset support area or the position deviation of the symmetrical support position of the prefabricated components is greater than or equal to the preset position deviation, it indicates that the support area is insufficient or the support position deviation is large, and the prefabricated component construction risk tendency type is accurately determined to be a strong risk tendency type. The above method improves the accuracy of identifying single risks and associated risks of prefabricated components, realizes the prediction of risk diffusion trends, and accurately captures risks and their chain reactions.

[0053] Specifically, the risk area identification module determines, under the condition of determining the risk area of prefabricated components, whether there are other risky prefabricated components within the risky prefabricated component impact range according to the prefabricated component construction risk tendency type, or determines the prefabricated component risk area based on the support sensitivity of the risky prefabricated components:

[0054] If the prefabricated component construction risk tendency type is a weak risk tendency type and there are other risky prefabricated components within the risky prefabricated component impact zone, the risk area identification module determines that the area where the risky prefabricated component is located is a risky area;

[0055] If the prefabricated component construction risk tendency type is a strong risk tendency type and the risk prefabricated component support sensitivity is greater than a preset sensitivity, the risk area identification module determines that the area where the risk prefabricated component is located is a risk area.

[0056] In the embodiment of the present invention, the support sensitivity of the risk prefabricated component is determined by the ratio of the support area change to the position deviation change. The preset support sensitivity is the average value of the support sensitivity of several times of the same type of goods under the same risk tendency type. For example, the support area change is 0.19m 2 Divided by the position deviation change of 0.03m, the support sensitivity is 6.33m / m 2 For example, the support sensitivity of two identical cargoes under the same risk tendency type is 4.2m / m 2 and 4.1m / m 2 The preset support sensitivity is 4.15m / m 2 However, the above value is not limited thereto, and those skilled in the art can also adjust the value according to actual needs.

[0057] The present invention determines whether there are other risky prefabricated components in the influence interval of the risky prefabricated component based on the risk tendency type of the prefabricated component construction, or determines the risk area of the prefabricated component based on the support sensitivity of the risky prefabricated component. According to the fact that the risk tendency type of the prefabricated component construction is a weak risk tendency type and there are other risky prefabricated components in the influence interval of the risky prefabricated component, it indicates that the risk tendency of a single prefabricated component itself is weak, but there are other risky prefabricated components within its influence range. The area where the risky prefabricated component is located is accurately determined to be a risk area. According to the fact that the risk tendency type of the prefabricated component construction is a strong risk tendency type and the support sensitivity of the risky prefabricated component is greater than the preset sensitivity, it indicates that the prefabricated component itself has a high risk tendency and the support system is more sensitive to position changes. The area where the risky prefabricated component is located is accurately determined to be a risk area. The above method improves the accuracy of identifying single risks and associated risks of prefabricated components, realizes the prediction of risk diffusion trends, and accurately captures risks and their chain reactions.

[0058] Specifically, under the condition that the diffusion analysis module determines the risk diffusion area, the risk diffusion area is determined based on the areas where the risk prefabricated components associated with the risk prefabricated components in the prefabricated component risk area are located, and whether there is a circumferential line between several prefabricated component risk areas that have a continuous position relationship:

[0059] If the area where the prefabricated components associated with the risky prefabricated components in the prefabricated component risk area are located is a non-risk area or a circumference exists between several prefabricated component risk areas that are in a continuous position relationship, the diffusion analysis module determines that the area is a risk diffusion area;

[0060] If the area where the prefabricated components associated with the risky prefabricated components in the prefabricated component risk area are located is a risk area and there is no circumferential line among several prefabricated component risk areas that are in a positional continuity relationship, the diffusion analysis module determines that the area is not a risk diffusion area.

[0061] In the embodiment of the present invention, the associated prefabricated components of the risk prefabricated components in the prefabricated component risk area include but are not limited to "the associated prefabricated components have functional associations, position associations, and construction sequence associations with the risk prefabricated components", and the circumference line is a distribution of the center points of several prefabricated component risk areas in space to form an approximate circle, so that the distance difference from the center point of each risk area to the center of the circle is within a preset tolerance, and the angle between the lines connecting adjacent center points meets the circumference equal division feature, and the preset tolerance range is set to ±0.2m-±0.4m, with a preferred value of ±0.3m. The selection of this preferred value can tolerate a certain degree of measurement and installation errors, and can more accurately identify the center points of risk areas with circular distribution characteristics. For example, after obtaining the coordinates of the center points of the five prefabricated component risk areas A, B, C, D, and E, the least squares method is used to fit the center and radius of the circle. After calculation, the distance difference from each point to the center of the circle is within the set tolerance of ±0.3m, and the angle between the lines connecting adjacent center points meets the circumference equal division feature, which determines that the line is a circular line. However, the above value is not limited to this, and those skilled in the art can also adjust the value according to actual needs.

[0062] The present invention determines the risk diffusion area by the area where the associated prefabricated components of the risk prefabricated components in the prefabricated component risk area are located, and whether there is a circumferential line among several prefabricated component risk areas with a continuous position relationship. According to the fact that the area where the associated prefabricated components of the risk prefabricated components in the prefabricated component risk area is a non-risk area or there is a circumferential line among several prefabricated component risk areas with a continuous position relationship, it indicates the possibility and regularity of risk diffusion, and the area is accurately determined to be the risk diffusion area. According to the fact that the area where the associated prefabricated components of the risk prefabricated components in the prefabricated component risk area is a risk area and there is no circumferential line among several prefabricated component risk areas with a continuous position relationship, it indicates that the risk areas are not closely connected and the possibility of diffusion is small, and the area is accurately determined not to be the risk diffusion area. The above method improves the accuracy of identifying single prefabricated component risks and associated risks, realizes the prediction of risk diffusion trends, and accurately captures risks and their chain reactions.

[0063] Specifically, the risk assessment module determines whether to enhance the support strength of the risk prefabricated components in the associated risk areas of the risk diffusion area, or dynamically monitors the area change rate of the risk diffusion area, based on the area of the risk diffusion area and whether the risk diffusion area is a construction completed area:

[0064] If the area of the risk diffusion region is larger than the area of the preset region or the risk diffusion region is a construction completed region, the risk assessment module determines the area change rate of the dynamically monitored risk diffusion region;

[0065] If the area of the risk diffusion zone is smaller than or equal to the area of the preset area and the risk diffusion zone is an unfinished construction area, the risk assessment module determines to enhance the support strength of the risk prefabricated components in the associated risk areas of the risk diffusion zone.

[0066] In the embodiment of the present invention, the dynamic monitoring of the area change rate of the risk diffusion area includes dynamically monitoring the area change rate of the risk diffusion area within a preset period, and adaptively adjusting the area change rate of the risk diffusion area under the condition that the area change rate of the risk diffusion area is greater than or equal to the preset area change rate (the average value of the area change rate of the risk diffusion area when risks occur under the same construction conditions for several times). The value range of the preset period is set to 1-4 days, and the value of the preset period is preferably 2 days. For example, in a high-rise residential building construction project, the construction team uses the risk assessment module to control the risks of prefabricated components. During the construction process, a risk diffusion area E is monitored, whose initial area is 25 square meters, which is larger than the construction team's area. The preset area is set at 20 square meters. According to the rules, the risk assessment module initiates dynamic monitoring of risk diffusion area E and its associated risk area F, focusing on the rate of change in the area of risk diffusion area E. Initially, the area of risk diffusion area E changes relatively steadily. However, within several cycles, measurements show that its area change rate reaches 1.2 square meters per hour, while the preset area change rate is 0.8 square meters per hour. This rate of change is greater than the preset area change rate. Based on this situation, the construction team immediately suspends installation work directly related to the risky prefabricated components in risk diffusion area E and its associated risk area F to avoid exacerbating the risk caused by continued construction. At the same time, a temporary protective fence is added around risk diffusion area E, increasing its height from 1.5 meters to 2 meters, and prominent warning signs are posted to prevent unauthorized personnel from approaching the danger zone.

[0067] In an embodiment of the present invention, enhancing the support strength of risk prefabricated components in the associated risk areas of the risk diffusion area includes adding temporary support columns or adjusting the positions of support points. The associated risk areas of the risk diffusion area are areas that are adjacent to the risk diffusion area in spatial position, are mutually related in structural force, or have a synergistic relationship in function, and also have risk prefabricated components. For example, in a high-rise residential building construction project, when the construction team is installing floor prefabricated components, a risk diffusion area G is identified through a risk assessment module. The area is 12 square meters, which is smaller than the preset area of 15 square meters set by the construction team, and the area is in an unfinished construction stage. According to the rules, the risk assessment module determines that the support strength of the risk prefabricated components in the associated risk area H of the risk diffusion area G needs to be enhanced. There are many large prefabricated concrete wall panels used to construct load-bearing walls in the associated risk area H. Some wall panels have already developed fine cracks, posing certain safety hazards. Based on the actual situation, the construction team decided to adopt a combination of adding temporary support columns and adjusting the position of the support points to enhance the support strength. First, for the prefabricated wall panels with cracks, temporary support columns are added symmetrically on both sides of them. The temporary support columns are made of high-strength steel. The bottom of each support column is equipped with a height-adjustable base that can adapt to different ground flatness. The construction team According to the design plan, the technicians used expansion bolts to firmly fix the base of the support column to the floor 50 cm away from the edge of the wall panel. The top of the support column was in close contact with the prefabricated wall panel, and pressure was slowly applied through the hydraulic jack to make the support column evenly share the load borne by the wall panel. At the same time, the construction team adjusted the position of the original support points. The original support points were concentrated at both ends of the prefabricated wall panel, and the force distribution was uneven. According to the structural characteristics of the wall panel and the results of the force analysis, the technicians added two support points in the middle of the wall panel and adjusted the support points to be evenly distributed. During the adjustment process, the total station and other measuring equipment were used to accurately determine the position of the support points to ensure that the connection between the support points and the wall panel was stable and reliable.

[0068] The present invention determines whether to enhance the supporting strength of risk prefabricated components in the associated risk areas of the risk diffusion area through the area of the risk diffusion area and whether the risk diffusion area is a completed construction area, or dynamically monitors the area change rate of the risk diffusion area. According to the fact that the area of the risk diffusion area is greater than the area of the preset area or the risk diffusion area is a completed construction area, it indicates that the risk diffusion range is large or the completed area is difficult to reinforce on site. The area change rate of the dynamically monitored risk diffusion area is accurately determined. According to the fact that the area of the risk diffusion area is less than or equal to the area of the preset area and the risk diffusion area is an unfinished construction area, it indicates that the risk diffusion range is controllable and is under construction. The supporting strength of risk prefabricated components in the associated risk areas of the risk diffusion area is accurately determined. The above method improves the accuracy of identifying individual risks and associated risks of prefabricated components, realizes the prediction of risk diffusion trends, and accurately captures risks and their chain reactions.
