Background

The expansion joint is a structural joint vertically arranged along a proper position in the length direction of a house for preventing the structure from cracking or damaging due to climate temperature change (thermal expansion and cold contraction). The expansion joint divides building components above a foundation such as a wall body, a floor slab, a roof (except a wooden roof) and the like into two independent parts, so that the building can horizontally expand and contract along the length direction.

In China, a plurality of bridge expansion joints are adopted in bridge construction, and most of the bridge expansion joints leak water. So that previously constructed bridges, the beam ends and cap beams below the expansion joints are most severely damaged by water. Because the expansion joint is difficult to ensure that the expansion joint is completely watertight, and the damage of the expansion joint to the beam end and the cap beam due to water leakage is very serious, the waterproof treatment for reinforcing the expansion joint is imperative, the waterproof design and the installation quality of the expansion joint must be treated as very important problems, and the rainwater of bridge deck sewage can be caused to flow disorderly due to the water leakage of the expansion joint, so that the concrete is corroded. The design of the drain hole is often considered to be poor, and the concrete around the drain opening and the beam plate under the drain hole is seriously corroded because the installation form and quality of the drain hole are not considered.
