Product Parameters

Product Introduction

The LSDLD-20 Professional Dam Piping and Leakage Detection Instrument is a new device designed and manufactured based on the fundamental principles of the "flow field method." It offers high precision, accuracy, and rapid detection of piping and leakage in the water intake and leakage channels of rivers and reservoirs. This instrument is suitable for detecting piping and leakage in various dam types, including earth dams, rock-fill dams, and concrete dams.
Comprising a transmitter, receiver, and sensor, the LSDLD-20 works together to send signals, capture data, and detect changes in the flow field. Advanced technologies such as pseudo-random current signal transmission and reception, near-field source strengthening technology, high-resolution rapid detection of current density fields, and multi-component detection of current density fields enhance its capabilities.
An embedded intelligent industrial control computer serves as the main platform, providing a user-friendly interface and the ability to connect to RTK (Real-Time Kinematic) systems and depth gauges for high-precision data collection and positioning.
During the flood season, the instrument quickly and accurately determines the specific location of piping and leakage, enabling timely and effective response measures, significantly reducing the resources needed for flood control and minimising losses to life and property. In the non-flood season, it can be used for the maintenance and management of dam structures in rivers and reservoirs, thereby protecting water resources. The LSDLD-20 is applicable for detecting various dam types and their foundations.


Features

1. Adjustable Output Voltage: The instrument offers five adjustable voltage levels, making it particularly suitable for fieldwork and practical applications.
2. Fully Digital Signal Acquisition and Processing Technology: This ensures stability and reliability in data handling.
3. Real-time Curve Plotting: The capability to plot curves in real-time allows for rapid anomaly analysis and localization directly on-site, providing immediate feedback on any irregularities detected.
4. Data Storage and Tagging: Real-time data can be stored and tagged, facilitating post-processing and the submission of results, which enhances the documentation and reporting process.

Application Case:

An on-site operation demonstration was conducted using the dam piping leakage detection instrument. The actual on-site working time was very short, including the construction wiring and surface water measurement, taking less than 3 hours in total. The task was completed quickly and accurately, achieving high precision and accuracy in detecting piping and leakage, thus providing a scientific basis for flood control work.
