Description

Technical Field

[0001] The present invention belongs to the technical field of building jacking, and in particular relates to a building collaborative jacking control method and system. Background Art

[0002] Masonry buildings with brick masonry as the main load-bearing material are increasingly suffering from problems such as uneven settlement, tilting or cracking due to improper operation and maintenance measures in the later stage, changes in load and foundation conditions, and the masonry structure's own sensitivity to deformation. The current main solution is to take countermeasures such as correction and reinforcement.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0043] Embodiment 1:

[0044] like Figure 1 As shown, a building collaborative jacking control method includes the following steps:

[0045] S1, collecting the building's external dimension data and inclination angle data; In S1, the building's external dimension data and inclination angle data are obtained by measuring with a total station;

[0046] S2, making a three-dimensional building model according to the data collected in S1, using the building plan drawings, the building's external dimensions data and the inclination angle data to make the building three-dimensional model, and designing a jacking strategy according to the building three-dimensional model;

[0047] The steps to design a jacking strategy based on the building 3D model are as follows:

[0048] S21. The center of gravity of the building is obtained by calculating the three-dimensional building model. The projection of the center of gravity of the building on the ground along the inclined direction is the axis, and the jacking positions are set on both sides of the axis;

[0049] S22, calculating the weight of the building through the three-dimensional model of the building, calculating the theoretical lifting force according to the finite element force analysis, and selecting the corresponding lifting component according to the theoretical lifting force;

[0050] S23, obtaining the total lifting height of each lifting position by comparing the building three-dimensional model with the corrected building three-dimensional model;

[0051] S24, evenly dividing the total lifting height into a plurality of sub-lifting heights, and dividing the lifting strategy into a plurality of lifting sub-strategies according to the sub-lifting heights.

[0052] In S24, the maximum total lifting height is calculated, the maximum total lifting height is evenly divided into a plurality of sub-lifting heights, the number of lifting sub-strategies is calculated, and the sub-lifting heights of each lifting position are calculated according to the number of lifting sub-strategies, and each sub-lifting height is not greater than 10 mm.

[0053] like Figure 2 As shown, point O is the projection of the building's center of gravity on the ground, the arrow direction is the building's tilt direction, the total lifting height of the lifting position H1 is 449mm, 441mm is divided into 50 sections, the height of each of the first 49 sections is 9mm, the height of the last section is 8mm, and the remaining lifting positions are divided into 50 sections according to this ratio. Each lifting sub-strategy contains the lifting height of the corresponding section of each lifting position. The lifting process of each lifting position starts and ends at the same time, and the lifting time of each lifting sub-strategy is 2 minutes.

[0054] S3, during the lifting process, displacement data of the building is collected, and the displacement data is fitted with the three-dimensional model of the building to generate a real building model; in S3, after the building is lifted according to the sub-lifting strategy, the stage displacement data of the building is collected, and the stage displacement data is fitted with the three-dimensional model of the building to generate a stage real building model;

[0055] S4, moving the building three-dimensional model according to the jacking strategy to generate an ideal building model; in S4, moving the building three-dimensional model according to the jacking sub-strategy to generate multiple stages of ideal building models.

[0056] S5. Compare the error between the ideal building model and the real building model. If the error exceeds a set threshold, modify the jacking strategy.

[0057] In S5, the error between the actual building model of the stage and the ideal building model of the corresponding stage is compared. If the error exceeds a set threshold, the jacking height of the corresponding jacking position of the next jacking sub-strategy is adjusted.

[0058] The error calculation process between the real building model in the comparison stage and the ideal building model in the corresponding stage is as follows:

[0059] The distance between the outer side of the real building model of this stage and the outer side of the ideal building model of the corresponding stage is calculated as the first distance.

[0060] The distance between the outer side of the ideal building model in this stage and the outer side of the ideal building model in the previous stage is calculated as the second distance.

[0061] The ratio of the first spacing to the second spacing is an error.

[0062] Set the threshold to 10%-30%.

[0063] If the real building model of this stage is located inside the ideal building model of the corresponding stage, the jacking height of the corresponding jacking position and the adjacent jacking position of the next jacking sub-strategy is reduced.

[0064] If the actual building model of a stage is located inside the ideal building model of the corresponding stage, it means that the actual lifting height is lower than the expected height. The lifting height of the corresponding lifting position and the adjacent lifting position in the next lifting sub-strategy needs to be reduced. The height of the adjacent lifting position is reduced to maintain the overall balance of the building and avoid new deviations caused by the height adjustment of a single position.

[0065] If the real building model of this stage is located outside the ideal building model of the corresponding stage, the jacking height of the corresponding jacking position of the next jacking sub-strategy is increased, and the jacking height of the adjacent jacking position is reduced in the next jacking sub-strategy.

[0066] Outer deviation adjustment: If the actual building model of a stage is located inside or outside the ideal building model of the corresponding stage, this indicates that the actual jacking height is higher than the expected height or there is uneven jacking. In order to correct this deviation, the height of the corresponding jacking position in the next jacking sub-strategy needs to be increased. In order to maintain balance and avoid excessive jacking, the height of the adjacent jacking position needs to be reduced in the next jacking sub-strategy, so that the building gradually returns to the predetermined jacking path and alleviates the stress concentration of the building structure.

[0067] The increased lifting height ratio is directly proportional to the error.

[0068] A building collaborative lifting control system, comprising:

[0069] A building data collection module, which is configured to collect building shape dimension data and inclination angle data;

[0070] The building data acquisition module adopts but is not limited to one of the existing laser scanners and total stations or a combination of the two.

[0071] The model generation module is configured to make a three-dimensional building model according to the data collected by the building data collection module, and design a jacking strategy according to the three-dimensional building model; the model generation module adopts existing three-dimensional modeling software.

[0072] A displacement data acquisition module, which is configured to acquire displacement data of the building during the jacking process;

[0073] The displacement data acquisition module adopts but is not limited to one of the existing displacement sensors and total stations, and detects the displacement data of key points of the building.

[0074] A model simulation module is configured to fit the displacement data with the building three-dimensional model to generate a real building model; and to move the building three-dimensional model according to the jacking strategy to generate an ideal building model;

[0075] A control module, which is configured to compare the error between the ideal building model and the real building model, and modify the lifting strategy of the lifting component if the error exceeds a set threshold;

[0076] The jacking component is equipped for jacking up the building base, and the jacking component adopts but is not limited to the existing hydraulic cylinder.

[0077] By detecting the displacement of the building during the jacking process to generate a real building model, and comparing the real building model with the ideal building model, deviations in the jacking process can be discovered in a timely manner, and the jacking strategy can be adjusted in a timely and dynamic manner to reduce rework and improve work efficiency.

[0078] The total lifting height is evenly divided into multiple sub-lifting heights, and multiple lifting sub-strategies are formed, which improves the controllability and safety of the lifting process. The real building model of the stage is generated according to the stage displacement data fitting, which helps to more accurately reflect the real-time status of the building and effectively prevent the problem of stress concentration in the building structure.

[0079] Adjusting the jacking height of the corresponding jacking position in the next jacking sub-strategy by adjusting the jacking strategy in real time requires a high degree of expertise and advanced control systems.

[0080] By using a total station to accurately measure the building's dimensions and inclination angles, a high-precision three-dimensional model can be produced, providing an accurate data basis for subsequent jacking strategy design.

[0081] The center of gravity, weight and lifting force of the building are calculated based on the three-dimensional model, and the lifting strategy is determined through finite element analysis, ensuring the scientificity and rationality of the lifting process.

[0082] The total lifting height is evenly divided into multiple sub-lifting heights to form multiple lifting sub-strategies, making the lifting process more controllable and reducing overall risks.

[0083] Dynamic error correction: By comparing the error between the ideal model and the real model and setting the error threshold, the lifting height can be adjusted dynamically to ensure the accuracy of the lifting process.
