Description

Technical Field

[0001] The utility model relates to the technical field of expansion joint detection, in particular to a road expansion joint damage detection device. Background Art

[0002] There are expansion joints and contraction joints in road engineering. They are mainly two ways to solve road deformation, dredging and restraint. The road expansion joint is the space gap reserved during construction. When the concrete expands due to heat, it occupies the vacant position without generating compressive stress inside. During construction, a compression joint strip is placed on the top of the concrete slab at the expansion joint position. After the concrete solidifies, the compression joint plate of the expansion joint is pulled out in time, and then the filler is poured in. The joint is connected from top to bottom, and the width of the joint is 1.5 to 2.5CM; the road contraction joint is to cut a joint in the overall road surface. When the concrete shrinks due to cold, the cut gap is pulled open without generating tensile stress inside. The cutting method is used during construction. That is, when the concrete reaches 50% to 70% of the design strength, it is cut into joints with a joint width of 3 to 5mm using a seam cutter. The contraction joint is generally 1 / 3 to 1 / 2 of the structural layer.

[0003] Rubber strips are usually installed in pavement contraction joints. The rubber strips will be damaged after long-term use. The rubber strips need to be inspected in time. Detecting the damage of the rubber strips requires the help of a detection device. The existing detection device has a complex structure, is inconvenient to operate, and has low detection efficiency and cannot meet the detection requirements. Therefore, it is necessary to design a road expansion joint damage detection device. Utility Model Content
