The present invention relates to a bridge drainage facility, in particular, by installing a "U" type drain pipe next to a firewall installed in bridges and overpasses of rivers, and serves as a drain pipe and perforated pipe, while reducing traffic accidents and durability due to body water, etc. It is to provide a bridge drainage facility using an improved "U" type drainage pipe to increase the number.

In general, bridges require a higher durability than general roads, and thus a waterproof layer is formed to protect concrete floorboards from rainwater or road water.However, since the bridge's ascon layer is permeable, rainwater or road water can be used as a stagnant water for a long time. In winter, as they are repeatedly frozen or thawed, deterioration of concrete slabs causes aggregate aggregation or layer separation, and the corrosion of reinforcing bars reduces the durability of bridges.

In order to solve this problem, a plurality of water collecting holes are installed at regular intervals at the edge of the road surface, and the water collecting pipes are provided with a through hole provided with a through hole to collect the infiltration water that has permeated the intersecting ascon layer. Through the discharge to the catchment through the rainwater or road surface water to prevent penetration into the concrete deck, but if the road surface is a smooth curve curve has a problem that the drainage can not be processed quickly.

Accordingly, the present invention has been invented to solve the conventional problems as described above, by installing a "U" type drain pipe next to the barrier wall, the bridge drainage using the improved "U" type drain pipe to be made faster The purpose is to provide the facility.

It is another object of the present invention to provide an interfacial drainage facility using an "U" type drainage pipe that is improved to serve as a function of a perforated pipe for draining the permeated water that has passed through the ascon layer.

In order to achieve the above object, the present invention, in the middle of the "U" type drain pipe 30 is formed in the longitudinal direction of the drainage path 32 for draining the road surface water inside the body 31, a plurality of catchment holes 40 Is installed to form a bridge drainage system for draining rainwater or road water flowing along the road surface, the "U" type drain pipe 30 is a drainage passage on the central upper side of one side (surface contacting the road surface) of the body 31 32 and a plurality of collecting holes 33 are communicated with each other at regular intervals and is installed long along the road surface between the edge of the road surface 10 and the protection wall 20 at the same height or slightly lower than the road surface 10, "U", characterized in that the front surface of the water collecting hole 33 is configured to drain the water through the water collecting hole 33 through the cross-linked ascon layer, which is provided with a known filter 35 for collecting foreign substances. Bridge drainage system And balls.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary view showing the configuration of a "U" type drain pipe according to the present invention, Figure 2 is a longitudinal sectional view of the "U" type drain pipe according to the present invention, Figure 3 is a "U" type drain pipe of the present invention It is a reference diagram showing the state of construction of the bridge drainage system using the.

As shown in the present invention, in the construction of a bridge drainage facility for draining road water, which is installed on a river bridge or overpass, the "U" type drain pipe is located between the edge of the road surface 10 and the barrier wall 20 ( 30 is installed long along the road surface, and the water collecting port 40 is connected to the middle of the "U" type drain pipe 30 so that the road surface water flowing down from the road surface is collected in the drain pipe 30 and then the water collecting port 40 is opened. It is configured to drain through.

The "U" type drain pipe 30 is constructed at the same height or slightly lower than the road surface 10 so that the road surface water flows into the drain pipe.

The " U " type drain pipe 30 has a body 31 formed in the " U " shape and a drainage path 32 formed inside the body to drain the road surface water, the body 31 being formed long in the longitudinal direction, and the body 31 In the center upper side of one side (surface contacting the road surface) of a plurality of collecting holes 33 having a predetermined size are arranged at regular intervals.

The catching hole 33 communicates with the drainage channel 32 of the body 31 to penetrate the intersecting ascon layer to penetrate the water into the concrete floor 50, and the drainage passage 32 communicating with the collecting hole 33. Is supposed to flow.

A filter 35 is installed on the front surface of the collecting hole 33 to filter foreign matters included in road surface water and infiltrated water so that the filter 35 filters foreign matters, thereby preventing the drainage passage 32 from being blocked by foreign matters. Doing.

According to the present invention configured as described above, when the barrier wall 20 is installed at the edge of the road surface 10, the “U” type drain pipe 30 is collected together between the barrier wall 20 and the road surface 10 to collect rainwater flowing down to the road surface. Then, install the cross-linked ascon layer, the upper end of the "U" type drain pipe 30 is constructed at the same height or lower than the road surface.

Then, the rainwater and road surface water generated on the road surface flows to the edge of the road surface and flows to the "U" type drain pipe 30 located between the barrier walls 20, and the road surface collected by the "U" type drain pipe 30. Water is discharged to the river or the ground through the catch 40 is installed in the middle of the "U" type drain pipe 30.

Therefore, the road surface water is not quickly drained as in the prior art, and it is possible to prevent the phenomenon of sticking to the edge of the road surface adjacent to the protection wall, as well as the penetration water that has permeated the intersecting ascon layer with the collecting hole 33 formed in the “U” drain pipe 30. It can be drained together.

As described above, the bridge drainage facility according to the present invention by constructing the "U" type drainage pipe 30 in the existing bridge bridge or bridge bridge drainage facilities to exert the role of drainage pipes and perforated pipes at the same time, you want By inducing it to be done, it is effective to greatly contribute to reducing traffic accidents due to body water and the durability of concrete structures.
