Ultrasonic Drill hole/groove monitor 8360 for testing the drillhole and groove quality
Application:
Used for testing the drillhole and groove quality of the railway, highway, sea port and other high buildings. It can test whether it has some fallen down place of the hole inside wall. According to the Ultrasonic detection method, it can test larger diameter holes with high precision.
Standard:
DGJ32/J 21-2009 Inspection and testing specification for construction engineering quality
DB 29-112-2004 Technical specification for the testing of the drilling hole of Cast-in-place pile and the Groove of Diaphragm wall
T/CECS 596-2019 Technical specification for testing of borehole of cast-in-place piles
T/CECS 597-2019 Technical specification for testing of diaphragm wall
JTG/T 3512 Technical Specification for foundation piles testing of highway engineering

Features:
1. The system adopts two strong steel line for probe guide and lifting, it can protect the signal cable.
2. It can use Li battery or 220V power supply to be suitable for different projects.
3. With small structure, it can be fixed in small car, so it can move easily from one place to another place, and easy to adjust position when put on the hole topside. The winch has probe lock structure, so it can protect the probe safely during movement.
4. Special signal processing method will avoid the affection from project, then confirm the signal stable, reliable and precise.
5. The probe is with strong power, so it has small blind area, it can test the min diameter 300mm and max diameter 11000mm hole. The mud ratio can be up to 1.4g/cm3. So it can be suitable for any hole and groove testing.
6. The probe can automatically lift and down during testing, and show the graph and hole image on time. It includes the depth, space, diameter, deviation, verticality.
7. The system has self-calibration function, it can auto calibrate based on the hole diameter or groove width
8. WIFI transmission method can transfer the data easily
9 C-LEAF 3D image calculation method to show the hole status directly
