Seismic wave detector, used for surface wave method foundation survey, reflection logging, refraction logging, tunnel and underground engineering geological advance detection, has the advantages of stability, convenient operation, high data repeatability, has been in highway foundation, seismic imaging tunnel detection products stable excellent performance, the whole machine light small portable, easy to operate, It is very suitable for production, scientific research, field experiments and other different working conditions, and is well received by customers. Changes in lithology in front of the face, such as irregularity, discontinuities, faults and fracture zones, can be detected using the product. As a prediction method, the product can be used not only in drill and blast excavation but also in TBM excavation without direct operation on the face.
1. The forecast range can reach 100 ~200 meters
2. no need to work directly on the palm surface, can avoid certain safety risks
3. the field test is convenient, the equipment runs independently, without external power supply and external computer
