Description
Technical Field
[0001] The invention belongs to the field of hydropower station dam safety monitoring, and in particular relates to a hydropower station dam seepage volume collection system and method. Background Art
[0002] my country has built more than 100,000 dams, which play an important role in economic construction and ecological environment development. Dams may be deformed, leaked, and damaged during normal operation, which may seriously threaten the lives and property of people downstream of the dam area. Dam safety monitoring can help us understand the operating status of dams, guide construction and operation, provide feedback on design, and reduce dam risks, which is crucial to the safe operation of dams. Due to the constant changes in the environment and external conditions of dams, their stability and safety need to be constantly monitored and evaluated. Among them, seepage observation is one of the important means of dam safety monitoring. Seepage refers to the amount of water that passes through the cross section of the soil or concrete structure perpendicular to the direction of the seepage water flow under the action of water pressure. Seepage observation is crucial to the safe and reliable operation of dams. Through seepage observation, problems such as leakage and deformation can be discovered and dealt with in a timely manner to avoid their impact on the safety and stability of the dam. There are thousands of seepage monitoring points in the foundation of a large hydropower station dam, which requires continuity and timeliness in the seepage measurement. The existing technology usually uses a measuring cup to measure the seepage of the dam body, and records the data manually for storage. The manual use of a measuring cup to measure the seepage of the hydropower station dam body is inefficient, and the manual handwriting of data often results in data errors or missing. At the same time, the measurement accuracy is often related to the mental state of the observer. The continuous high labor intensity can easily cause fatigue to the observer, and the measurement accuracy is difficult to guarantee. Therefore, it is necessary to design a hydropower station dam seepage collection system and method to solve the above problems. Summary of the invention
