More Information
Summary:The utility model provides a surface subsidence monitoring device for a deep water zone. The device is characterized in that a liquid storage tank of a silicon pressure type settlement gauge is fixed to a settlement plate, a silicon pressure sensor is fixed to a reference pile, the liquid storage tank is flexibly connected with the silicon pressure sensor to form an airtight self-balance system, and the airtight self-balance system is arranged in a foundation soil layer; then, the change of elevation difference is calculated through the change of liquid pressure in a test system to obtain the settlement amount of a foundation surface layer. The device has the advantages of being simple in structure, convenient to operate, strong in adaptability, high measurement precision and the like, can realize real-time automatic monitoring, greatly reduce labor cost and improve working efficiency, and has wide application value.
