The pressure measuring hose is a kind of pore water pressure meter commonly used in seepage pressure monitoring. Because the pressure measuring hose has simple structure, convenient observation, reliable measurement and durability. It is widely used to monitor the pressure of dam foundations, seepage flow around dams, seepage lines of earth and rock dams, and other groundwater level monitoring on specific occasions. Pressure gauge hose water level can be observed manually, such as sounding bell and electric level gauge, etc. It can also be used for telemetry, such as telemetering level gauge. In recent years, the telemetering osmometer has also been placed in the bottom of the pressure measuring hose to measure the height of the water column, which is converted into the pressure hose water level, and can be automatically monitored. The design, construction, and management of pressure measuring hoses are thoroughly described or stipulated in the dam safety monitoring regulations and related professional books. In the time work, safety monitoring workers have also created many effective methods and experiences. It is also worth learning and promoting.
