Introduction
With the rapid advancement of technology, 3D modeling technology is increasingly applied in water conservancy project management. In water conservancy management, the application of 3D modeling technology is gradually becoming an important means to enhance management efficiency and improve decision-making accuracy. The Tianjin Binhai Moiture-proof Gate, as a crucial water conservancy project in the Haihe River Basin, directly affects the flood control safety and water resource optimization of the region. To achieve refined management of the tide gate, advanced technology combinations such as SLAM2000 + D2000S + LIDAR2200 have been introduced to perform high-precision, large-scale 3D modeling of the tide gate and its surrounding environment.
Background
The Tianjin Binhai Moiture-proof Gate is the last defense before the Haihe River flows into the sea and is a key control node in the eastern sea barrier of the "Tianjin Urban Flood Control Circle." This gate not only bears the responsibility of flood and tide control but also directly impacts the economic and social development and ecological civilization construction in the Haihe River Basin and the Beijing-Tianjin-Hebei region. However, traditional management methods suffer from inefficiencies and inaccurate data, making it difficult to meet the needs of modern water conservancy management. Therefore, the introduction of 3D modeling technology has become a necessary choice for improving the management level of the tide gate.
Technology
SLAM XS07 (Handheld 3D Laser Scanning Device):
Features: High precision, high speed, portability.
Application: Used for detailed 3D modeling of the tide gate and its surrounding environment, providing accurate spatial data.
D2000S (Drone Surveying System):
Features: Wide coverage, high flexibility, real-time data transmission.
Application: Combined with LIDAR2200 data, it conducts large-scale terrain surveying, providing a macro perspective for the operation and scheduling of the tide gate.
LIDAR2200 (Laser Radar):
Features: Long-distance measurement, high-precision point cloud data.
Application: Used to monitor water level changes, water flow speed, and other key parameters upstream and downstream of the tide gate, providing scientific basis for flood control decisions.
Solution
1.Preparation Phase
l Equipment Calibration and Adjustment: Ensure that SLAM XS07 handheld 3D laser scanning device, D2000S drone surveying system, and LIDAR2200 laser radar are in good working condition and perform necessary calibration to ensure data accuracy and reliability.
l Site Survey: Conduct a detailed on-site survey of the Tianjin Binhai Moiture-proof Gate and its surrounding environment to understand terrain, obstacles, flight safety zones, etc., preparing for subsequent data collection.
l Data Collection Plan: Based on the site survey results, formulate a detailed data collection plan including drone flight routes, data collection times, and data quality requirements.
Data Collection
Handheld 3D Laser Scanning with SLAM XS07：Use the SLAM XS07 to perform detailed 3D scanning of key parts of the tide gate, such as the gate doors, gate chambers, and internal areas, to obtain high-precision point cloud data. This data will be used to construct a detailed 3D model of the tide gate.
Drone D2000S + LIDAR2200：Deploy the D2000S drone to conduct large-scale terrain surveying of the top of the tide gate and its surrounding environment according to pre-planned flight routes. The drone, equipped with the high-precision LIDAR2200 laser radar, can collect real-time surface images and point cloud data, providing data support for constructing a macro 3D model.
3.Data Processing and Model Construction
l Data Preprocessing: Perform noise reduction, filtering, and stitching on the collected point cloud data to improve data quality. Simultaneously, perform geometric correction and stitching on the drone-captured image data to generate high-resolution orthophotos.
l 3D Modeling: Import the preprocessed point cloud data and image data into 3D modeling software and use professional software to create 3D models. By constructing detailed 3D models of the tide gate and its surrounding environment, the structural features, terrain, and surrounding environment of the tide gate can be visually represented.
l Model Optimization: Optimize and adjust the initially constructed 3D model to ensure accuracy and realism. At the same time, use real-time data from the LIDAR2200 to dynamically update the model, maintaining its timeliness and accuracy. Construct an information management system for the tide gate, integrating data from SLAM XS07, D2000S, and LIDAR2200 to achieve real-time monitoring, early warning, and optimization scheduling. Introduce digital twin technology to build a digital twin of the tide gate for virtual simulation and predictive analysis.
Application Effects and Significance
l Enhanced Management Efficiency:
Through mobile devices such as smartphones, managers can access real-time information on the operation status and water conditions of the tide gate, enabling refined management and increased efficiency. Real-time data monitoring and early warning systems allow managers to swiftly respond to various emergencies, ensuring the safe operation of the tide gate.
l Optimized Resource Allocation:
Accurate modeling and data analysis provide scientific bases for scheduling the tide gate, achieving optimized water resource allocation. During non-flood periods, adjusting the gate opening levels helps ensure that water from the Haihe River flows naturally into the sea, aiding the urban river network. During flood periods, preemptively opening the gate to release water provides more time and space for flood safety.
l Promotion of Regional Development:
The efficient operation of the tide gate provides strong support for the economic and social development of Tianjin Binhai New Area and the Haihe River Basin. As a protected cultural relic and immovable revolutionary monument, the reinforcement and digital management of the tide gate not only preserve the water conservancy heritage but also attract numerous visitors, making it a well-known "hotspot."
Outcome
The application of SLAM XS07 + D2000S + LIDAR2200 technology in the Tianjin Binhai Moiture-proof Gate has significantly improved the management level and operational efficiency of the tide gate. Through precise modeling, real-time monitoring, information management, and intelligent operation, refined management and scientific scheduling of the tide gate have been achieved. This technology not only ensures the safe operation of the tide gate and flood safety but also promotes regional economic and social development and ecological civilization construction. In the future, with continuous technological advancements and expanding application scenarios, 3D modeling technology will play an important role in more fields.
