Detail

Characteristic

Parameter

The equipment can test the density of the grouting of the tunnel, the quality of the concrete pouring (the strength and rigidity of the test piece, the strength of the test piece), the effective prestress under the anchor, the material and size of the concrete. It has the characteristics of high test efficiency, good reliability and no damage to the structure, which can greatly improve the quality assurance of the prestressed beam.

Results and technical characteristics
Based on the integration of existing advanced technologies at home and abroad, a series of test principles were proposed and a relatively complete detection system was established. The main independent research and development technologies are:
Equivalent Wave Velocity Method (IEEV): Positioning and type discrimination of grouting defects of prestressed beams;
Equivalent mass method (TTEM): testing the tension of a buried anchor/rod;
Full Length Attenuation Method (FLEA): Qualitative testing of the channel grouting density of prestressed beams;
Transfer Function Method (PFTF): Characterizes the grouting defects in the vicinity of the anchor head of the prestressed beam. According to this, not only can the effective tension of various anchor cables/rods be tested, the grouting compactness of the prestressed beams can be quickly qualitatively detected, accurately positioned and typed, and at the same time, the concrete material (structure, test piece), beam thickness It can also be tested.
