RAIN LEAKAGE PREVENTING APPARATUS OF EXPANSION JOINT SECTION OF BRIDGE}

The present invention relates to a rainwater leak installed in the lower portion of the expansion joint of the upper slab forming the upper structure of the bridge, more specifically, to prevent rain water from falling to the lower portion of the upper slab, and to prevent corrosion of the members installed in the bridge The present invention relates to a rainwater leak structure of the upper slab expansion joint section of a bridge to discharge the fluid such as rainwater to the lower portion of the bridge through the rainwater leak receiver so as to prevent it.

In general, the bridge is composed of an upper structure and a lower structure, the upper slab constituting the upper structure is installed so that the expansion joint is installed at a predetermined distance to operate against the contraction and expansion according to the seasonal change of the upper slab.

1 is a view showing a side cross-sectional state of expansion joints of a general bridge, the bridge 90, the bridge device 30 is seated on the top of the coping 20 of the bridge 10, the above bridge device 30 The girder beam 40 is seated on the top of the), and concrete is poured on the top of the girder beam 40 to form the upper slab 50.

The upper slab 50 is provided with an expansion joint 60 between the upper slab and another upper slab so as to prevent damage to the structure due to shrinkage and expansion of the concrete.

The slab drain pipe may be installed in the upper slab of the above-mentioned bridge, but when a large amount of rainwater is poured, the problem of frequent occurrence of rainwater flowing from the upper part of the expansion joint to the lower part, the freeze phenomenon of the upper slab, the girder beam Many problems can occur such as corrosion of the bridge, corrosion of the bridge arrangement, and freezing of the bridge coping (decreased in concrete strength).

In addition, there is a problem in that due to corrosion of the seating device supporting the upper slab, there is a problem of causing a sudden collapse of the bridge in relation to the contraction and expansion, which is a seasonal change.

In addition, the expansion joint of the upper slab is a problem such as being incompatible with the surrounding scenery due to the corrosion caused by the inflow of rain water to damage the aesthetics.

The present invention, in order to solve the above problems, the present invention, the freeze phenomenon of the top slab due to the inflow of rainwater, corrosion of the girder beam, corrosion of the bridge device, and freezing of the coping of the pier (decreased concrete strength), etc. In addition to completely eliminating the cause, the aesthetics are beautiful, and the lower part of the bridge can provide a parking lot or a resting place for people to rest, and it can also discharge rainwater from the upper slab of the bridge to the lower part completely. It is an object of the present invention to provide a rainwater drainage structure in the upper slab expansion joint section of a bridge having an open structure.
