Purpose:

The instrument is special instrument used to detect and determine elevation of concrete filling pile. It is suitable to detect concrete elevation of filling pile underwater as per Shanghai Industry Standard DGJ08-11 "Design Code for Building Foundation" and DBJ08-202 "Bored Pile Construction Specification", or similar specification of other province. It is also suitable to detect concrete elevation of filling pile underwater for other piles.

Adopts computer techniques, it can collect, analyze, calculate and process signal automatically. It has characteristics of accurate data collection, rapid answer time, high automation, reliable test data, and timely sound and light alarm, so the operator can determine and control preset position of filling pile effectively. This solves the problem that there is no instrument to detect concrete elevation of filling pile in the past. It can highly improve qualification rate of filling pile. It is the best instrument for companies and institutes, which are for high building, road and bridge, harbor and dock, marine oil platform construction.
