Description

Bridge Linear Drainage System

The present invention relates to a bridge pre-watering system, and more particularly, it is possible to extend the life of the asphalt by easily discharging the infiltrated water that has penetrated into the asphalt formed on the slab of the bridge, and at the same time reduce the noise caused by the falling rainwater. It is related to the bridge senior water system.

A drainage system is installed on the bridge to drain rainwater. Rainwater that falls on the asphalt of the bridge flows to the vertical drainage pipe on the asphalt and is collected, but not a small amount of the rainwater penetrates into the asphalt (hereafter, rainwater that penetrates into the asphalt is referred to as “permeate water”). After the rain stops, the asphalt surface of the bridge dries quickly, whereas the permeated water that has penetrated into the asphalt accumulates in a specific area or takes a long time to dry, which can reduce the life of the asphalt. Therefore, a technique for installing a separate perforated pipe has been proposed to quickly remove the infiltrated water, but this incurs additional construction costs and in many cases the infiltration water discharge function cannot be properly performed due to foreign matter getting caught over time. .

Furthermore, rainwater collected and flowing through the vertical drainage pipe falls onto the vertical drainage pipe through the transverse drainage pipe, and at this time, a large noise is generated in the vertical drainage pipe due to the fall. In densely populated areas, residential buildings or commercial facilities are often built under bridges, so this noise is also a cause of civil complaints.

And in the construction process of the bridge, especially in the construction of the side protection wall, the conventional bridge water supply system was constructed so that the transverse drainage pipe protruded from the side of the formwork for forming the side protection wall from the beginning, so it was difficult to place the side protection wall using a machine.
