Widely Usage Seismograph Micro-seismic Survey Test equipment
An engineering seismograph is a device specifically used to monitor and record ground vibrations. It is widely used in engineering projects such as buildings, bridges, and tunnels. The following is a detailed introduction to engineering seismographs:
Product Overview:
WZG-24C engineering seismograph is mainly composed of three parts: a seismometer, an amplification system, and a recording system. It can directly pick up earthquake vibrations and convert them into energy forms that can be recorded by the instrument. The electrical signals are recorded in different ways to analyze the propagation law of seismic waves in the earth's crust.
Key Features:
The main functions of the engineering seismograph include transient multi-point Rayleigh wave exploration, shallow reflection measurement, shallow refraction measurement, wave velocity (shear wave) measurement, multi-wave high-density seismic imaging, pile foundation detection, civil engineering quality detection, site constant micro-motion measurement and vibration blasting measurement. These functions make it widely used in foundation, roadbed and foundation engineering detection, tunnel engineering detection, operation observation of large and medium-sized reservoirs, bridge engineering detection, and environmental and geological disaster detection and evaluation.
Application Areas:
Engineering seismographs are widely used in many fields. In geotechnical engineering, they can be used to detect underground structures, evaluate foundation stability, and monitor seismic activity; in mineral and hydrogeology, they can be used for resource exploration and groundwater monitoring; in engineering geology, they can be used to evaluate the safety of buildings and monitor the impact of earthquakes on engineering structures; in environmental and geological disaster detection and evaluation, they can be used for landslides, karst, mudslides, goafs, and active fault surveys.
