TECHNICAL FIELD
[0001] The application relates to the technical field of joint waterproofing, in particular to a highway bridge joint waterproofing device. BACKGROUND
[0002] The highway bridge joint, also known as a contraction joint, is a structural joint arranged at a proper position of a construction joint in a direction of a highway bridge to prevent cracks or damage of the structure caused by climate temperature changes (thermal expansion and cold contraction). The contraction joint is composed of a top plate, a base and a rubber waterstop. The rubber waterstop is clamped into the F-shaped, E-shaped or L-shaped clamping groove of the base through the edges on both sides. Since the length of the contraction joint is generally long, it is difficult to clamp the rubber waterstop into the base by pressing. When a large number of rubber waterstops need to be replaced due to aging, it is particularly difficult to pull out and reinstall the rubber waterstop when the gap between the base and the bridge is small.
