Description

Technical Field

[0001] This disclosure relates to monitoring and visual technologies, and in particular to a method, apparatus, electronic device, and storage medium for monitoring foundation pits. Background Technology

[0002] Monitoring of ultra-deep foundation pit projects can be divided into two categories. The first category uses techniques based on geological survey data and geotechnical tests, involving fixed-point and periodic observations. The second category includes real-time data acquisition, wireless transmission, data aggregation and analysis, and over-limit early warning alarms throughout the entire foundation pit construction process.

[0003] The first type of monitoring method uses mature equipment and technology, is relatively simple to operate and has a relatively low cost, but has poor real-time performance and cannot reflect changes in the foundation pit in a timely manner. The monitoring frequency and density are limited, and some key changes may be missed.

[0004] The second type of monitoring method offers strong real-time performance, enabling timely detection of changes in the foundation pit and prompt action. Data accuracy is high, with automated equipment reducing human error. Monitoring frequency is high, and data collection is comprehensive, providing a detailed reflection of the foundation pit's condition. However, the investment cost is higher, requiring the purchase and installation of automated equipment, as well as professional personnel for system maintenance and management. Furthermore, it relies on network and power supplies, necessitating the assurance of stable communication and power supply.

[0063] Figure 1 This is a flowchart illustrating a foundation pit monitoring method in one embodiment of this disclosure. Figure 1 As shown, the foundation pit monitoring method includes the following steps:

[0064] S1: Construct a three-dimensional building information model that includes the target foundation pit, the support structure of the target foundation pit, and the surrounding environment.

[0065] In some optional embodiments of this disclosure, a target building modeling software is used to model a software drawing including a target foundation pit to obtain a three-dimensional building information model.

[0066] The Revit software was used to import CAD drawings of the construction project's foundation pit into the software and create a 3D BIM model of the foundation pit and its surrounding environment. Revit is the name of a software suite. The Revit suite is built for Building Information Modeling (BIM) and helps architects design, build, and maintain higher-quality, more energy-efficient buildings.

[0067] S2: Based on the support structure, set up monitoring points for the target foundation pit.

[0068] In some optional embodiments of this disclosure, the monitoring location and number of monitoring points for the target foundation pit are determined based on the support structure; and monitoring points for the target foundation pit are set up based on the monitoring location and number of monitoring points.

[0069] After the model is built, set up monitoring points for the foundation pit at the construction site, ensuring consistency with the monitoring points in the model. The requirements are that monitoring points must be set up in the middle of the foundation pit perimeter, at the external corners, and near the protected object. The horizontal spacing should not exceed 20m, and there should be no fewer than 3 monitoring points on each side. The number and spacing of monitoring points can be adjusted according to accuracy requirements.

[0070] S3: Determine the standard structural parameters of the support structure.

[0071] In some optional embodiments of this disclosure, standard structural parameters such as verticality and horizontality of the foundation pit support standard are formulated according to the definition of standard foundation pit support. This standard is used to analyze and judge whether the foundation pit has settlement, tilting, or instability.

[0072] S4: Based on standard structural parameters and information on multiple foundation pit defects corresponding to multiple foundation pits, construct a foundation pit defect database.

[0073] In some optional embodiments of this disclosure, based on standard structural parameters, information on foundation pits that have tilted, settled, or cracked is queried in the foundation pit information database. The foundation pit defect information includes information on foundation pit tilting, settling, or cracking. Based on the foundation pit information query results, information on foundation pit tilting, settling, or cracking is extracted from the foundation pit information database to generate a foundation pit defect data database.

[0074] A database of foundation pit information is constructed using historical data from network monitoring or the company's own foundation pit monitoring. This database includes information on foundation pits with various quality problems and those without. Information on foundation pit instability, tilting, settlement, or cracking is retrieved from this database. Based on the query results, a database of foundation pit defect data on failure modes is created.

[0075] S5: Update the 3D building information model based on the on-site progress of the target foundation pit.

[0076] The 3D model of the foundation pit and its surrounding environment is updated in Revit software in real time according to the on-site construction progress.

[0077] S6: Based on real-time images of the target foundation pit, a database of foundation pit defects, and an updated 3D building information model, determine whether the target foundation pit has quality defects.

[0078] In some embodiments of this disclosure, a quality defect analysis is performed based on real-time images of the target foundation pit, historical images of the target foundation pit, and a foundation pit defect database to determine a first quality analysis result for the target foundation pit; based on the updated three-dimensional building information model, a model output image of the target foundation pit is output; an overlay analysis is performed on the real-time images and the model output image, and a second quality analysis result for the target foundation pit is determined based on the overlay analysis result; based on the first quality analysis result and the second quality analysis result, it is determined whether a quality defect has occurred in the target foundation pit.

[0079] Real-time image data of the target foundation pit and its surroundings are collected using drones according to the time requirements. The obtained image data is compared and analyzed with historically collected image data. Based on the foundation pit defect data database, it is determined whether the target foundation pit shows images consistent with existing foundation pits such as tilting / settlement / cracking. At the same time, the images are overlaid with the images of the foundation pit BIM model in Photoshop software for image analysis. If the support structure is not found to overlap in the two images, it indicates that the support structure has tilted or settled. If they can overlap completely, it indicates that the support structure is normal.

[0080] In this embodiment, a 3D BIM model of the foundation pit and its surrounding environment is established using Building Information Modeling (BIM) technology. Monitoring points are set up around the foundation pit according to specifications. A comprehensive database of foundation pit defects such as settlement, tilting, and instability is built. Standard definitions and descriptions of foundation pit support are formulated. The standard model of the foundation pit is updated in real time according to the progress on site. Visual technology, along with the database and BIM model, is used for detection and analysis to determine whether the foundation pit is unstable. This invention is simple to operate and can overcome the shortcomings of current foundation pit monitoring methods.
