の排水構造に関するものである。Description: TECHNICAL FIELD The present invention relates to a drainage structure for a bridge pavement having a waterproof layer, such as a passage bridge, an elevated road bridge, an elevated parking lot, and the like. More specifically, a bridge provided with a waterproof layer for providing a continuous drainage guideway between the joints of the pavement of the bridge surface, which allows continuous water flow, and effectively drains rainwater penetrating to the lower part of the pavement surface. It relates to the drainage structure of a surface pavement.

処理を行ってきた例もある。Waterproofing methods include a sheet-based waterproofing material, a synthetic rubber-based coating waterproofing material, an asphalt-based coating waterproofing material, and a pavement-based coating waterproofing material. However, a bridge pavement in which a waterproof layer is provided on a floor slab by such a method and a pavement is constructed thereon may have an opposite effect to the purpose of providing a waterproof layer. That is, the rainwater that has penetrated the pavement is blocked by the waterproof layer and accumulates on the waterproof layer along the curb or ground cover, and the accumulated water deteriorates the pavement and causes damage to the pavement. Therefore, it is necessary to promptly remove the water that has penetrated the pavement, and wastewater treatment measures have become an important issue that determines the success or failure of installing a waterproof layer. Therefore, as a drainage treatment measure, a drain outlet is opened on the wall of the expansion device (joint part) of the bridge pavement, and a drain outlet is opened on the side of the drainage basin installed adjacent to the curb or ground cover. Wastewater treatment. There is also an example in which a hole is made in a floor slab and a drainage pipe is buried in the hole to perform drainage treatment.

る。(Problems to be Solved by the Invention) However, in the wastewater treatment using such a drainage structure, since the form of the wastewater treatment is a pointwise wastewater treatment, the drainage is incomplete, and the wastewater near the drainage basin is possible. However, there is a disadvantage that the water on the waterproof layer between the joint and the drainage basin or between the drainage basin and the drainage basin remains without being drained. And the peeling phenomenon occurs on the pavement,
Eventually, it causes pavement damage. Therefore, the drainage treatment by the line structure, not the drainage treatment by the point structure, completely eliminates the water accumulated on the waterproof layer between the joint part and the drainage basin, or between the drainage basin and the drainage basin, and prevents the pavement from peeling. It is desired to prevent the pavement from being damaged.

And a continuous drainage channel is provided to completely eliminate the water accumulated on the waterproof layer, prevent the pavement from peeling off, and provide an excellent drainage structure of the bridge pavement to maintain the durable pavement. .
