The present invention relates to a bridge and an elevated roadway on which a vehicle operates, and more particularly, to a design to prevent rain water leakage to the lower portion of the firewall is installed on the upper sleeve to prevent the vehicle from falling.

In general, an upper sleeve is installed on a bridge or overpass via a bridge device on the upper part of the bridge, and the upper sleeve is connected by an expansion joint to receive the impact load due to the weight and movement generated when the vehicle passes. It is installed, and both sides of the sleeve is provided with a protective wall to prevent the fall of the vehicle is installed.

In the bridge or overpass, rainwater generated in the upper sleeve during rainy weather should be drained quickly, and in the case of an overpass in which the vehicle is driven downward, drainage of the rainwater generated in the upper sleeve may be important.

The reason is that when the rainwater generated in the upper sleeve of the elevated roadway is drained through an unspecified number of places, when the rain drops on the glass of the vehicle while driving down the elevated roadway, the driver's vision is obstructed. It may cause traffic accidents, and if rainwater leaks through a large number of unspecified areas, it may be fatal for the contractor's image management.

Rainwater leaks on bridges and overpasses often occur in the lower part of the barrier where the expansion joint is installed.

Rain water leaks to the lower part of the barrier located at the site where the expansion joint is installed. The reason why the expansion joint is free to cause displacement and deformation caused by the movement of the vehicle This is because it cannot be fixed to the device, and therefore, water leakage is inevitable at the point where the expansion joint and the barrier are fitted.

As a conventional method of preventing the leakage of rainwater to the lower portion of the barrier wall positioned on the expansion joint device, the barrier wall is wrapped with a steel plate.

As described above, if the protection wall is wrapped with a steel plate, rainwater leaked between the gaps of the protection wall may be prevented. Rainwater leakage could not be prevented at the point where the expansion joint and the barrier meet.

Therefore, the applicant has come up with a technique that can quickly remove rainwater from the upper sleeve while preventing the leakage at the point where the barrier and the expansion joint meet while maintaining the displacement and deformation of the expansion joint. .

The present invention was devised to solve the shortcomings of the conventional bridge or overpass, and its purpose is to improve the structure of the joints and rubber plates of the expansion joints so that displacements and deformations occurring in the upper sleeves can be made smoothly. Even when the barrier is installed on the sleeve, the expansion and deformation of the expansion joint can be made smoothly, and the rainwater can be quickly discharged through the drain hole formed on the bending rubber plate while preventing the leakage occurring at the intersection between the driveway, the sidewalk and the barrier. By allowing drainage, it prevents slipping of vehicles caused by rainwater accumulated on the upper sleeve, and prevents secondary accidents caused by rainwater leaking by preventing the leakage of rainwater that occurred between the barriers. Bridges with barriers to prevent An object of the present invention is to provide a leak prevention apparatus at an elevated road.

The present invention for achieving the above object is installed to the connection portion of the upper sleeve which is mounted to the top of the pier is installed expansion and contraction apparatus to receive the impact load due to the weight and movement caused by the movement of the vehicle, In the bridge or overpass made of a barrier wall to be installed on both sides of the upper sleeve to prevent the vehicle from falling,

On the bolt 14 formed on the flat plate 13 of the joint 10 in which the anchor cover 12 is placed and fixed to the end portions of the upper sleeve 100 that are installed at the upper portion of the piers facing each other via the bridge mechanism. The hole 31a of the vibration noise absorbing part 31 having a width and a thickness capable of effectively receiving the vibration and noise transmitted from the upper sleeve 100 is fitted and assembled, and according to the displacement and deformation of the upper sleeve 100. It protrudes on both sides of the upper sleeve 100 further having a horizontal rubber plate 30a having only the elastic portion 32 which is made to stretch smoothly, and a drain hole 32a for discharging rainwater generated in the upper sleeve 100. Connection protrusions formed on the surfaces facing each other to prevent rain water leakage at the same time to be made of the connection of the bending rubber plate (30b) is extended to be fixed by the fixing bolt 301 to the inner surface of the barrier wall 300 With 33 As the rubber plate 30 connected by the connecting groove 34 is integrally formed with respect to the barrier wall 300, the barrier plate is characterized in that it prevents leakage occurring at the intersection between the driveway part and the sidewalk and the barrier. It is achieved by a leak prevention device on a bridge or overpass.
