High-precision dam foundation grouting stratum lifting detection device
The invention discloses a high-precision dam foundation grouting stratum lifting detection device. The high-precision dam foundation grouting stratum lifting detection device is composed of two solenoid differential micro-displacement sensors, a double-detection shockproof safety base and a stratum lifting detection display and alarm system. In the device, each solenoid differential micro-displacement sensor is decomposed into two independent parts, namely a cylindrical coil main body and an armature, the upper solenoid differential displacement sensor is used for measuring the lifting displacement of stratum during grouting, and the lower solenoid differential displacement sensor is used for measuring the disturbance displacement of an upper metal positioning plate caused by environmentalfactors. The double-detection shockproof safety base is fixed to the cement ground through expansion screws; and a lifting recorder finishes processing, displaying and alarming of lifting displacement and disturbance displacement signals and the lifting recorder comprises a high-amplitude-stabilization excitation source, a phase-sensitive detector and a V/A conversion circuit, wherein the phase-sensitive detector is used for processing output signals of a sensor. The device can adapt to the severe environment of grouting engineering, is firm and durable, improves the stability and continuityof detection, remarkably reduces the failure rate of lifting detection, and is very high in resolution.
