Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a drainage device for a bridge having a side drainage pipe,

In particular, the present invention relates to a bridge drainage apparatus, and more particularly, to a drainage apparatus for a bridge capable of easily discharging rainwater infiltrated into a packing layer, facilitating installation of a catchment port, facilitating adjustment of a slope of a line discharge pipe, To a drainage device of a bridge having one side drainage pipe so as to block inflow.

Generally, since the top plate of the bridge is made of concrete or steel, the coefficient of thermal expansion is different from that of the asphalt, which is a packaging material, and thus a gap is formed at the interface between the upper plate body and the asphalt pavement layer. When such a gap is formed, rainwater or foreign matter penetrates, and the service life of the package is shortened. Therefore, a drainage facility capable of draining the rainwater infiltrated in the generated gap is required.

As a background technology of the present invention, a Korean Registered Utility Model Registration No. 20-0417944 has proposed a " bridge infiltration water drainage structure ". A plurality of infiltration water inflow holes / a plurality of road surface water inflow holes respectively formed in the side wall and the ceiling portion of the box body, and a plurality of road surface water inflow holes formed in the bottom portion of the box body, And at least one drain pipe for discharging inflow water and a flange extending upward at one end of the box body and fixed to a barrier of the bridge top plate via an anchor bolt, A box; And a mesh type absorbing panel sandwiched between a side surface of the asbestos packing layer and the infiltration water inflow hole of the drain box to absorb infiltration water infiltrating into the asphalt pavement layer and guide the infiltrated water to the drain box, The infiltration water penetrated into the inside of the pavement layer is quickly drained to prevent cracking and breakage of the asbestos pavement layer caused by infiltration water.

However, the above background art has a problem in that when the absorption panel is used for a long time, the mesh is clogged and the functions of absorption and drainage are deteriorated and the processing ability of the bridging water is deteriorated.

The transverse port tube 50 has one end connected to the longitudinal port tube 60 and the other end connected to the lateral pipeline 70 It is connected. The transverse hole (50) and the longitudinal hole (60) have small holes distributed in the surface. The longitudinal tube 60 is disposed in the longitudinal tube tube pocket 201. The longitudinally oriented perforated pipe 60 is positioned in the longitudinally positioned pipe pocket 201 by an angle bracket 62 fixed to the water collecting channel 20 at regular intervals. Thus, the longitudinally-oriented perforated pipe 60 flows the rainwater flowing into the gap between the collecting channel 20 and the package layer 16 and flows through the transverse pipe 50 to the transverse pipe 70.

The transverse port hole 50 and the longitudinal port hole 60 are formed in the package layer 16 by draining the rainwater flowing between the water catching channel 20 and the long gap of the package layer 16 through the lateral water pipe 70, The clearance between the packing layer 16 and the collecting channel 20 as well as the clearance can be quickly removed.
