It is known.

However, in the case of Registered Patent Publication No. 1263000 among the above-described prior technologies, the road surface is sloped downward toward the inlet pipe on the bridge's protective wall side and the inflow pipe is constructed in a straight shape facing the side, so the initial inflow space for the water is narrow and the inflow is limited. There was a problem in that the movement of running water through the pipe was not smooth, which lowered the drainage efficiency, which ultimately resulted in water stagnation on the bridge and blockage due to accumulation of dirt in the inlet pipe.

In addition, in the case of Registered Patent Publication No. 2017871 among the above-described prior technologies, the transverse drain pipe penetrates the bridge structure and is installed at an angle to improve the mobility of flowing water through the pipe, while in the case of Registered Patent Publication No. 1263000, the integrated and standardized There was a problem of poor constructability due to difficulty in installing the inlet pipe or lateral drain pipe.
