Embodiment 1

[0029] see figure 1 , is a schematic diagram of the structure of the detection method for the detachment of the electrode plate joint on the electrothermal concrete pavement provided by this embodiment. The detection method comprises steps S1-S4:

[0030] S1: Measure the current intensity I of each power supply branch line on the electrothermal concrete pavement i , and judge whether each power supply branch line is a suspected fault line, where: i≥1.

[0031] This step is used to obtain suspected fault lines. Specifically, see figure 2 , the steps include steps S11-S13:

[0032] S11: Use a clamp meter to measure the current intensity I of each power supply branch line on the electrothermal concrete pavement i , where: i≥1.

[0033] This step is used to measure the current intensity of each power supply line. Preferably, in the present embodiment, adopt clamp meter to measure the current intensity of each power supply branch line on the electrothermal concrete road sur...

Abstract

The invention discloses a method for detecting the electrode plate joint shedding phenomenon of an electrothermal concrete pavement. The method comprises the steps of S1, measuring the current strength Ii of each power supply branch of the electrothermal concrete pavement, and judging whether each power supply branch is a suspected faulty line or not, wherein i is larger than or equal to 1; S2, powering on each suspected faulty line, and measuring the strengths of magnetic fields at each measuring point of a live line and each measuring point of a null line; S3, through the formula (img file = 'DDA 0001226839360000011. TIF 'wi = '177 'he = '118 ' / ), calculating the ratio of magnetic field strengths at each measuring point measuring point of the live line and each measuring point of the null line, wherein Ri represents the ratio of magnetic field strengths at the i measuring point, mli and mni respectively represent the magnetic field strengths at the i measuring points of the live line and the null line; S4, calculating the change rate of the magnetic field strength according to each magnetic field strength, and determining the shedding position of an electrode plate joint according to the change rate of the magnetic field strength. Based on the method provided in the invention, the specific shedding position of the electrode plate joint can be rapidly and accurately determined. Therefore, the lossless diagnosis for the electrode plate joint shedding phenomenon of the electrothermal concrete pavement can be realized.

Description

technical field [0001] The invention relates to the technical field of electrothermal concrete pavement, in particular to a detection method for the detachment of electrode plate joints on electrothermal concrete pavement. Background technique [0002] A large number of investigations and studies have shown that the quality of the road surface is one of the important factors affecting road traffic. Especially in the cold winter, when the road is covered with snow or ice, it often has a serious impact on the smoothness of the road and driving safety, and even causes the closure of roads and airports, which brings inconvenience to passenger and cargo transportation, thus causing huge economic losses. loss. my country has a vast territory, and the areas with annual average snow days ≥ 30 days account for 56% of the national territory, including the northeast and west of my country. Even in the southern part of our country, there were severe ice and snow disasters similar to t...
