Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain for a seepage water drainage device provided as a drainage facility for a bridge.

[0002]

2. Description of the Related Art In recent years, when paving a bridge surface, it is customary to waterproof the floor slab prior to pavement for the purpose of protecting the floor slab and preventing damage to the pavement, and then paving the slab. ing. However, in the case of a bridge pavement in which a waterproof layer is provided on the floor slab and pavement is laid on it, rainwater that has penetrated the pavement is blocked by the waterproof layer, contrary to the purpose of applying the waterproof layer. The water accumulates on the waterproof layer along the path, and the accumulated water deteriorates the pavement and causes damage to the pavement.

Accordingly, the applicant of the present application has filed Japanese Patent Application No. 8-1575.
After laying a drainage frame body provided with water holes in a substantially U-shaped long structure having a cross section perpendicular to the axis, the drainage frame for drainage pavement drainage in No. 85, that is, on the waterproof layer, A permeated water drainage system that lays over a pavement and uses a modified drainage basin to connect the side of the drainage basin to the drainage frame, and allows the water accumulated on the waterproof layer to efficiently flow into the drainage basin. Has been filed.

[0004] However, there is a problem that the conventional drainage basin needs to be modified and the cost increases. In addition, the conventional drainage basin is provided so as to protrude into the roadway, thereby hindering the passage of vehicles. Further, since the size of the seepage drainage device is different, the road surface is not preferable in view of the scenery.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention does not obstruct the drainage of the seepage water drainage device provided on the bridge from obstructing the traffic of the vehicle, is excellent in scenery, and can be freely opened and closed to remove dust and the like. An object of the present invention is to provide a drainage hole for a seepage water drainage device provided as a bridge drainage facility that can be easily performed.

[0006]

In order to achieve the above-mentioned object, a drainage hole for a seepage water drainage device according to the present invention is installed by dividing a place where a curb on the side of a bridge and a seepage water drainage device are located. It is a substantially box made of steel plate following the outer periphery of the vertical cross section of the curb and the seepage water drainage device. A lid is provided to make it easier to clean dust and the like deposited inside.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a drainage port for a seepage water drainage device provided as a bridge drainage facility according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing a preferred embodiment of a seepage water drainage outlet provided as a bridge drainage facility according to the present invention, and FIG. 2 is provided as a bridge drainage facility according to the present invention. It is a partially cutaway perspective sectional view in the state where the lid of the drainage port for the seepage water drainage device was opened.

In FIG. 1, (V) is a bridge,
(W) is a curb located on the side of the bridge, and a seepage water drainage device (X) is provided along the curb (W). The seepage water drainage device (X) is disposed on the waterproof layer (Y), and the waterproof layer (Y) is provided with a normal pavement and a drainage pavement (Z). Are installed flush with the pavement (Z) surface.

The drain port for the seepage water drainage device of the present invention is installed at a part of the bridge (V) where the curb (W) and the seepage water drainage device (X) are located. (W)
And a seepage water drainage device (X). A substantially box (1) formed of a steel plate following the outer periphery of a vertical cross section of the box, and the box (1) has a drain hole (2) on the bottom surface. Is provided, a back plate (1b) having a height of a curb (W) is provided on a rear surface, and a front plate having a height of a seepage water drainage device (X) is provided on a front surface. (1c) is provided, and on both sides,
Strips (1d) and (1d) having the height of the thickness of the waterproof layer (Y) laid on the bridge (V), the front plate (1c), the bottom plate (1a) and the rear plate (1b), respectively. The interior space of the box (1) is a water reservoir, the upper part follows the outer periphery of the vertical cross section of the curb (W), and the lower part is the seepage water drainage. The device (X) is provided with a lid (1e) having a shape following the upper surface of the outer periphery of the vertical cross section.

The lid (1e) is pivotally connected to the upper end of the back plate (1b) at the upper end by a hinge (3).
Bolts (4) are provided at both lower ends of the lid (1e), and are pierced into receivers (5) (5) projecting horizontally from both upper ends of the front plate (1c). It is screwed with the provided bolt holes (5a) and (5a) to normally close the lid (1e).

Further, the front plate (1c) and the lid (1)
The lower part of e) is provided with a plurality of water inlets (6a) and (6b), respectively, to collect rainwater flowing on the pavement surface, and to penetrate the pavement surface and from the waterproof layer (Y). The flowing rainwater is also collected in the reservoir.

The lid (1e) may be provided with a handle hole (1f) for opening and closing, and the bottom plate (1a) of the substantially box (1) constituting the water storage portion is provided with permeated water. The rainwater flowing from the drainage device (X), the drainage pavement (Z), and the waterproof layer (Y) is connected to the gutter or the like through the drainage hole (2) when the bridge is used on a highway or the like. And drains rainwater and the like that accumulates in the water storage section into drainage basins and drains on the ground.

[0013]

As described above, the drain for a seepage water drainage device according to the present invention has the following effects. That is, the drain is
It is installed in the box approximately where the curb and permeated water drainage system conventionally installed are located, does not occupy a special place on the bridge, and the drainage basin does not protrude into the carriageway as in the past. Is safe, and the box is
Since it is formed according to the vertical cross-sectional shape of the curb and the seepage water drainage device connected thereto, there is no distinction between the seepage water drainage device and the drainage port, and therefore, there is no sense of discomfort and the landscape is improved.

Further, since the lid is openable and closable, it has an extremely useful effect such as easy removal of dust and the like deposited on the seepage water drainage device.
