Overview
Emissions and Stack Multi-Channel Concrete Flaw Detector for Pile Testing is designed for assessing pile foundation integrity using the cross-hole acoustic wave transmission method. This device features a unique multi-channel self-emission and self-receiving function, enabling full-profile concrete pile testing with only one lift when using three or four embedded acoustic testing pipes. This greatly improves efficiency and simplifies the detection process. It can test multiple profiles per lift at high speed, ensuring quick and reliable results. The device displays all profile information on one screen, giving a clear view of the pile’s overall quality. With multiple testing modes including horizontal, inclined, retest, and fine increment testing, it allows for precise identification of defects within pile shafts. Its sturdy, waterproof, damp-proof, and dustproof case makes it well-suited for field conditions, ensuring durability and long service life.
