Description

TECHNICAL FIELD

[0001] The utility model relates to underground water monitoring technical field especially relates to a kind of intelligent underground water seepage monitoring devices for soil layer. BACKGROUND

[0002] The high-low change of underground water seepage directly affects the strength and long-term stability of soil body, and further relates to the safety and reliability of building. The change of underground water seepage can cause various geological problems, such as soil softening, liquefaction and settlement. These problems not only affect the bearing capacity of foundation, but also increase soil pressure and reduce the anti-floating capacity of foundation. Therefore, accurately grasping the underground water seepage information within the scope of underground foundation is crucial for the protection of underground foundation. During the operation of building foundation, long-term monitoring of underground water seepage dynamics helps to assess the changes in the surrounding hydrological environment and provide scientific basis for daily maintenance. Monitoring of foundation settlement deformation and underground water seepage change can help to monitor the changes in foundation settlement in real time, so as to detect, analyze and handle problems early, thus solving problems at the initial stage. The monitoring content mainly includes surface settlement observation, deep horizontal displacement observation, pore water pressure observation and deep layered settlement. Common test items include underground settlement marker, underground water level gauge, pore water pressure gauge, layered settlement instrument and inclinometer. The monitoring method usually involves surface settlement monitoring and deep horizontal displacement observation. However, the existing underground water seepage monitoring technology has the following defects: (1) limited monitoring range, traditional monitoring methods mostly use point sensors, which cannot fully cover the entire site, and the monitoring results are easily affected by local geological conditions, so the overall underground water seepage dynamics cannot be accurately reflected; (2) low data collection frequency, many traditional monitoring systems rely on manual periodic data collection, which is time-consuming and labor-intensive, and cannot realize continuous and real-time monitoring, which may miss critical underground water seepage changes; (3) data transmission and processing lag, traditional systems have delays in data transmission and processing, which cannot timely feedback monitoring results, affecting the timeliness and accuracy of monitoring; (4) lack of intelligent early warning function, most existing systems do not have intelligent early warning function, which requires manual data analysis and judgment of whether measures need to be taken, increasing the risk of human error.
