Non-destructive testing device and method for reinforced concrete bridge steel bar corrosion

Abstract

The invention discloses a non-destructive testing device for reinforced concrete bridge steel bar corrosion. The non-destructive testing device drives a connection bracket to move through a transmission trolley, a guide rod is arranged on the connection bracket, testing equipment capable of sliding is arranged on the guide rod, and the testing equipment and the guide rod stretch to the lower end surface of the bridge through the connection bracket. The invention also provides a non-destructive testing method for reinforced concrete bridge steel bar corrosion based on the device. The invention has the beneficial technical effects that a new bridge testing device is provided, which enables the testing equipment to finish the bridge testing operation in a posture of getting close to the lower end surface of the bridge; the testing precision and accuracy are relatively high, and the structure is simple and convenient to control.

Description

technical field [0001] The invention relates to a bridge reinforcement corrosion detection technology, in particular to a reinforced concrete bridge reinforcement corrosion non-destructive detection device and method. Background technique [0002] The corrosion of reinforced concrete bridges includes two aspects: one is the corrosion of concrete; the other is the corrosion of steel bars. The latter mainly affects the durability of reinforced concrete bridge structures and is the most important factor in the failure of reinforced concrete bridge structures. There are many reasons for the corrosion of steel bars inside the concrete, and the various phenomena caused by corrosion are also very different. Generally, only regular inspections can be used to detect and check; the problem with existing detection methods is: because the steel bars are buried inside the bridge Under normal circumstances, it is invisible from the outside, and the existing detection methods can only...

Problems solved by technology

There are many reasons for the corrosion of steel bars inside concrete, and the various phenomena caused by corrosion are also very different. Generally, only regular inspections can be used to detect and check; Under normal circumstances, it is invisible from the outside, and the existing detection methods can only detect the problem after the corrosion degree of the steel bar has developed to the macro level; another problem is that the bridge is relatively thick, and it is difficult to detect it from the upper end of the bridge. Problems Existing in the Reinforcing Bars at the Lower End of the Bridge
