Proprietary wide-area signal pickup device to ensure the quality of the collected signal

Planar imaging, accurate positioning

product description

 BQIM management visualization

For the track board structure, a custom wide-area signal pickup device is specially customized to ensure the quality of the collected signals;

The surface wave method is used to detect cracks, which is less affected by steel bars, moisture, and crack surfaces;

Based on the classic FFT spectrum analysis method, the MEM spectrum analysis method is introduced for more diverse and smarter analysis methods.

 Achievements and technical characteristics

Test object: CRTS-Ⅲ track board

Test content: track slab voiding, crack depth, track slab concrete damage

Test items

1. "Non-destructive Testing Rules for Railway Tunnel Lining Quality" (TB 10223-2004)

2. "High-quality Railway Tunnel Construction Quality Acceptance Standard" (TB 10753-2010)

According to the standard

 Track plate void detection—shock echo method (IE method)

The track board vacancy detection adopts the impact echo method (IE method), and the collection diagram is as above. The elastic wave signal is continuously excited along the surface of the track plate, and the signal will reflect when it encounters loose media such as voids and voids. By extracting the abnormal reflection signal and performing corresponding processing, the position and depth of the void can be identified
