Recently, our company's patent “Inspection equipment and method for measuring the buried depth of steel pipe columns using impact elastic waves (patent number: ZL 200610003437.6)” was selected as the 2018 major scientific and technological innovation achievement database of transportation.
The public information is as follows:
Corrugated beam steel guardrail is the most common safety facility used on highways. The fence post is the main load-bearing component of the fence. Whether the buried depth of the column can meet the design requirements directly determines whether the fence can play a safety protection role in a traffic accident.
Different barrier columns have different requirements for the burial depth. The burial depth of the columns must meet the national regulations or design requirements to ensure the normal functioning of the safety fence.
Based on the nondestructive testing technology of shock wave, the steel guardrail column buried depth impact elastic wave detector developed by our company can quickly and accurately detect the buried depth of the wave beam steel guardrail column buried in soil / concrete. Is currently the only effective non-destructive testing instrument for steel fence post depth detection.
It has the following technical characteristics
Solve the testing difficulties of typical hollow thin-walled structures of steel guardrails;
The data is fully analyzed and objective.
"National Traffic Safety Facility Quality Supervision and Inspection Center" produced and issued inspection certificate or test report in compliance with national standards (GB / T 24967-2010);
Quick and easy operation: dual selection of touch screen and remote control operation, each pillar test only takes 7 minutes;
High test accuracy: The average measurement error is better than ± 4% or no more than ± 8cm, and the resolution of the tester for the test length is not less than 1cm.
