Description

Technical Field

[0001] The utility model relates to the technical field of tunnel seepage monitoring, in particular to tunnel seepage monitoring equipment. Background Art

[0002] Seepage monitoring mainly focuses on factors such as flow rate, water level and water pressure. By monitoring the seepage situation, the scope of seepage influence around the tunnel can be determined and appropriate drainage measures can be taken, which helps prevent damage to the tunnel structure caused by excessive water pressure and ensures the construction safety of the water diversion tunnel.

[0003] In order to ensure the safe operation and safety management of tunnels, it is very important to conduct seepage detection and safety evaluation on the built tunnels, especially after the tunnel is filled with water, water pressure load is generated, and under the action of the upstream and downstream water level difference, seepage is generated on the dam body, dam foundation and around the dam. The seepage rate is the basic element reflecting the seepage state, and it is an intuitive, sensitive and comprehensive factor reflecting the seepage safety problem. It reflects the working status of the impermeable body in a comprehensive and timely manner. When the seepage pressure observation and judgment of many engineering changes are not clear enough, the seepage rate reflection is already quite obvious, and it is impossible to observe the water level changes of the pressure measuring holes in the permeable layer where the seepage is more concentrated. Therefore, a tunnel seepage rate monitoring equipment is needed to improve the above problems. Utility Model Content
