Abstract

The present invention discloses a device for soil pressure detection, and a soil pressure monitoring system and method. The device for soil pressure detection comprises a container filled with gases,the container comprises a hollow ball body and a breather pipe having one end arranged in the hollow ball body, a pipe port arranged at the other end of the breather pipe is provided with a seal piececonfigured to seal the container, and a gas pressure sensor and a temperature sensor are arranged at a position, corresponding to the inner side of the breather pipe, on the seal piece. The device for soil pressure detection, and the soil pressure monitoring system and method can effectively induce soil pressure change in each direction with no need for arrangement of a plurality of soil pressureboxes, the soil pressure is accurate in measurement, implementation is simple, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of soil pressure measurement, and in particular relates to an earth pressure detection device, an earth pressure monitoring system and a method. Background technique [0002] At present, earth pressure gauges commonly used in China to monitor earth pressure mainly include steel string earth pressure cells. Its working principle When the soil stress in the measured structure changes, the sensing plate of the earth pressure gauge will feel the change of stress synchronously, and the sensing plate will be deformed, and the deformation will be transferred to the vibrating wire to change the stress of the vibrating wire, thereby changing the vibrating wire. vibration frequency. The electromagnetic coil excites the vibrating wire and measures its vibration frequency. The frequency signal is transmitted to the reading device through the cable, and the compressive stress value of the measured structure can be measu...
