Leakage channel detection system and method based on motion trail analysis

Abstract

The invention discloses a leakage channel detection system and method based on motion trail analysis. The system comprises a plurality of leakage detection micro terminals and leakage detection analysis equipment, wherein the leakage detection micro terminal comprises a leakage detection shell and a space motion trail recording module fixedly arranged in the leakage detection shell, the leakage detection micro terminal is thrown to a high water level side, flows through a leakage channel in a leakage body, and reaches a low water level side, and the motion trail parameters stored in the microleakage detection terminal are collected through the leakage detection analysis equipment. According to the invention, the leakage detection micro terminals are used for collecting the space motion trail from the high water level side to the low water level side through the leakage channel of the leakage body, and the space motion trail analysis is carried out through the leakage detection analysis equipment, so that information such as the inlet position, the outlet position, the leakage track and the like of the leakage channel of the leakage body is obtained, and a basis is provided for formulating leakage treatment measures of the leakage body; and the system is clear in scheme principle, simple to operate, accurate in test and applicable to concentrated leakage channel detection and analysis of most common leakage bodies such as dams, embankments and the like.

Description

technical field [0001] The invention relates to the fields of water conservancy and hydropower, geotechnical engineering, etc., and in particular to a leakage channel detection system and method based on motion track analysis. Background technique [0002] In the construction of dams, tunnels (holes), underground powerhouses, mine shafts, subways and other projects, different types of water leakage are often encountered. Leakage will not only bring economic losses to the built reservoirs (dams), but also may threaten the safety of dams, such as the Montrek Dam and Camaraza Dam in Spain, the Gran Charevo Dam in the former Yugoslavia, and the United States. Reservoir dams such as Harasba Dam and Dapuba Dam, my country's Shandong Shore Reservoir, Hunan Fangyuan Reservoir, and Guangxi Bagong Hydropower Station cannot store water for a long time due to a large amount of water leakage, or barely store water for operation at low water levels; Water seepage from (soil) stone cofferda...

AI Technical Summary

Problems solved by technology

However, seepage is usually caused by many reasons, and its burial conditions are relatively complex, theoretical analysis is difficult, and many conditions are required; in the case of deep burial, strong interference, and complex boundary conditions, the accuracy of physical detection methods is low and the resolution is low. Low; although the drilling detection accuracy is high, the efficiency is low and the workload is heavy; the tracer method generally can only give the location of the leakage inlet and outlet, and cannot judge the leakage channel, so it is difficult to find a method suitable for all leakage detection The above methods have their own limitations, and there is still no reliable, efficient and suitable method to detect and accurately find the leakage channel
