Description

Technical Field

[0001] The invention relates to a method and equipment for evaluating structural safety in a construction phase. Background Art

[0002] During the construction process, especially during the structural construction stage, since the integrity of the building structure has not yet been fully formed, its ability to resist external disturbances is relatively weak. During this period, if it encounters natural disasters such as strong winds, heavy rains, earthquakes, etc., the building structure may face safety risks, which can easily lead to safety accidents. However, the structure is always changing dynamically during the construction stage, and designers often only perform earthquake and wind resistance calculations on the final state of the building structure, and there is almost no safety analysis of the structure at each stage of construction in the above-mentioned natural disasters. Summary of the invention

[0003] The purpose of the present invention is to provide a method and device for evaluating the safety of a structure during construction.

[0004] In order to solve the above problems, the present invention provides a method for evaluating the safety of a structure during construction, comprising:

[0005] The construction status acquisition system identifies the image and video data of the on-site construction site and exports the on-site construction status information to the construction progress acquisition system;

[0006] The natural disaster information collection system collects real-time warning information issued by the Meteorological Bureau and the Earthquake Bureau, and combines it with map information to predict the time and extent of impact of extreme weather or natural disasters on the construction site;

[0007] The construction progress collection system dynamically predicts the construction progress on site when extreme weather or natural disasters occur based on the project department's construction progress plan, site conditions, emergency factors and construction status information;

[0008] The BIM model synchronization module converts the structural design model into a construction phase structural model corresponding to the time of impact of natural disasters on the construction site based on the information transmitted by the natural disaster information collection system and the construction progress collection system and in combination with the structural design model;

[0009] The safety assessment module uses finite element software to perform safety analysis on the structural model of the construction phase.

[0010] Furthermore, in the above method, the construction status acquisition system identifies the image and video data of the on-site construction site and derives the on-site construction status information, including:

[0011] The construction status acquisition system is based on CNN or RNN machine learning technology to identify the image and video data of the on-site construction site and export the on-site construction status information to the construction progress acquisition system.

[0012] Furthermore, in the above method, before the construction status acquisition system recognizes the image and video data of the on-site construction site, it also includes:

[0013] Visual monitoring equipment using high-definition cameras, drones and laser scanners are installed at the construction site to capture images and video data of the construction site in real time.

[0014] Furthermore, in the above method, the on-site construction status information includes: the number of planar components installed on each floor and the connection status of the components.

[0015] Furthermore, in the above method, the site conditions include: the current status of construction personnel, machinery and materials.

[0016] Furthermore, in the above method, the emergencies include: design changes, material supply delays, bad weather and safety and quality accidents.

[0017] Furthermore, in the above method, the safety assessment module uses finite element software to perform safety analysis on the structural model in the construction phase, including:

[0018] The safety assessment module uses finite element software to perform safety analysis on the structural model of the construction phase.

[0019] Furthermore, in the above method, the safety assessment module uses finite element software to perform safety analysis on the structural model in the construction phase, including:

[0020] When the natural disasters are typhoons and rainstorms, the safety assessment module conducts wind resistance analysis on the structural model during the construction phase;

[0021] When the natural disaster is an earthquake, the safety assessment module performs seismic analysis on the structural model during the construction phase;

[0022] When the natural disasters occur in the form of extremely high temperatures or severe cold, the safety assessment module conducts temperature response analysis on the structural model during the construction phase.

[0023] According to another aspect of the present invention, there is further provided a computer-readable storage medium having computer-executable instructions stored thereon, wherein when the computer-executable instructions are executed by a processor, the processor is caused to: adopt any of the methods described above.

[0024] According to another aspect of the present invention, there is also provided a computer device, comprising:

[0025] Processor; and

[0026] A memory arranged to store computer executable instructions which, when executed, cause the processor to: employ a method as described in any one of the above.

[0027] In summary, in order to solve the problem of lack of structural safety analysis in the construction phase, the present invention proposes a new method for evaluating the structural safety in the construction phase based on BIM and artificial intelligence technology. The on-site construction status is acquired through a construction status acquisition system, and the time of occurrence of natural disasters is predicted through a natural disaster information acquisition system. The construction progress corresponding to the occurrence of natural disasters is predicted through a construction progress acquisition system. At the same time, the structural design model is retrieved, and the construction phase structural model corresponding to the occurrence of natural disasters is output to perform a safety assessment on the structure at this time.

[0028] The present invention is based on BIM and artificial intelligence technology to achieve real-time prediction of the probability of structural failure during the construction phase, so as to ensure the safety of the construction process and the stability of the structure, prevent safety accidents that may be caused by force majeure factors, and protect the safety of personnel and property at the construction site.

[0029] Compared with the current structural safety analysis in the construction stage, the beneficial effects of the present invention are mainly as follows:

[0030] (1) Strong real-time performance. The present invention provides a construction phase structural safety assessment method based on BIM and artificial intelligence technology, which can automatically collect on-site progress and dynamically adjust the construction phase model based on the collected progress plan, extreme weather, natural disasters and other information;

[0031] (2) Targeting strong. The construction phase lasts for a long time. If modeling and calculation are performed for each phase, a lot of manpower and material resources will be required. This method only analyzes the construction phase model when extreme weather and natural disasters may occur, which greatly saves computing resources. BRIEF DESCRIPTION OF THE DRAWINGS
