In general, a bridge forms a frame with a reinforcing bar structure on top of the bridge after establishing a plurality of bridges, and concrete is poured into the frame of the reinforcing structure to form a bridge deck.

In the above, the bridge deck has a length change such as the length of the roof plate increases or decreases due to temperature changes occurring according to seasons, and in order to compensate for the expansion and contraction of the bridge deck, the bridge deck has a plurality of units (bridge slab). The slab and the slab are elastically connected.

In addition, the expansion joint is provided between the slab and the slab of the bridge forming the bridge deck in the above, the plurality of bridge slabs forming the bridge deck by the expansion joint is protected from damage caused by the expansion phenomenon and at the same time Vehicles will run smoothly.

However, the expansion joint device of various configurations applied to the expansion joint portion of the bridge as described above, although it is flexibly stretched according to the contraction and expansion of the bridge top plate, it is made of a structure that is difficult to prevent the penetration of water, so it is vulnerable in rainy weather and has low stability. There was this.

In addition, the Korean Patent No. 10-922599 prevents rainwater and earth and sand from flowing between the slab and the slab of the bridge and prevents the leakage of the slab to the lower part of the slab, and transfers the drain plate that can be used semi-permanently from the upper part of the slab to the lower part of the bridge. Both sides of the drain plate are reliably supported by the buried frame in the buried frame installed on both sides of the slab of the slab, and it is easy to install, reducing work time and cost according to the work, and embedded in the slab of the drain plate and the bridge. The buried frame leakage preventing device of the bridge which can improve the productivity by the simple structure of the buried frame can be replaced by the sliding method in the side of the bridge.

However, the conventional leak prevention devices are formed in such a way that the upper protrusion plate of the buried frame, which is accommodated at both ends of the drain plate, extends in the lateral direction of the insertion space, so that a defect occurs at the lower end of the upper protrusion plate during manufacturing.
