Referring to FIGS. 1 to 7, the line drainage device 100 of a bridge according to an embodiment of the present invention includes a trench 200, a grating 300, and a composite assembly guide 400.

In particular, the pre-drainage device 100 for a bridge according to the present invention is installed at the edge or center of a civil engineering building such as a road or a bridge, and serves to guide drainage of rainwater, and the like.

The trench 200 forms a space inside along the axial direction to guide rainwater and the like to guide drainage.

In addition, the trench 200 is buried in the shoulder protection wall 20 of the bridge slab 10, and forms a front opening 210 to allow rainwater to flow in.

In detail, the trench 200 is buried in the shoulder protection walls 20 at one or both edges along the longitudinal direction of the bridge slab 10, particularly in the vehicle driving direction.

At this time, one trench 200 may be provided continuously along the length direction of the bridge slab 10, or a plurality of trenches 200 may be disposed adjacent to each other. For convenience, a plurality of trenches 200 are provided along the longitudinal direction of the bridge slab 10.

In addition, the trench 200 includes a rear surface 211, an upper surface 212, a lower surface 213 and a front surface 214.

By the rear surface 211, the upper side 212, the lower side 213 and the front side, the trench 200 guides the flow of rain by forming a space therein. At this time, any one of the plurality of trenches 200 or the set trench 200 connects the transverse drainage pipe 30 to the rear surface 211. Thus, rainwater flows through the trenches 200 arranged in a row and is discharged to the set position through the transverse drainage pipe 30. Of course, the shape and number of the transverse drainage pipe 30 are not limited.

In particular, the front surface 214 extends upward from the lower side 213. At this time, the height of the front surface 214 is formed lower than the height of the rear surface 211. Thus, the front opening 210 is formed by a space between the upper surface 212 and the front surface 214.

In addition, the trenches 200 arranged in a row are constrained and connected by a connection bracket 220. In particular, the connection bracket 220 surrounds the upper side 212, the rear side 211, the lower side 213 and the front side 214 of the adjacent trench 200 and is fixed by welding or the like. The trench 200 is reinforced by a connection bracket 220. Of course, the connection bracket 220 can be deformed into various shapes.

In addition, the grating 300 is detachably installed in the trench 200 to open and close the front opening 210, and an inlet hole to allow rainwater to flow into the trench 200 while preventing the inflow of foreign substances having particles exceeding the set value. Through the (310).

In this case, one grating 300 may be provided for one bridge slab 10 and connected to a plurality of trenches 200 arranged in a row at the same time, or may be provided to correspond to the trench 200 one-to-one.

In addition, the grating 300 is not limited to the shape and number of the inflow holes 310.

On the other hand, the composite assembly guide 400, so that the grating 300 guides the opening and closing of the front opening 210, the grating 300 is rotated from the front side of the trench 200, or the opening of the trench 200 It serves to allow assembly and disassembly while guiding the slide movement in the lateral direction.

That is, the grating 300 rotates while being hinged to the trench 200 by the composite assembly guide 400 and opens and closes the front opening 210, or slides inserted in the open side of the trench 200. It is assembled in the set position.

In detail, the composite assembly guide 400 includes a holder 410, a locking portion 420, and an assembly support portion 430.

The holder 410 is formed along the axial direction of the trench 200 at the upper side of the trench 200 corresponding to the upper side of the front opening 210, is open to the front side, and has an inner space 416. That is, the holder 410 is formed extending from the front edge or the front edge of the upper side 212 of the trench 200.

In this case, the holder 410 is continuously formed on the upper side 212 along the axial direction of the trench 200, which is a direction arranged in a line.

In particular, the holder 410 includes an upper member 412 and a lower member 414.

The upper member 412 is formed to extend from the upper surface of the upper surface 212, and the lower member 414 is formed to extend from the lower surface of the upper surface 212. Accordingly, an inner space 416 is formed between the upper member 412 and the lower member 414. In addition, the holder 410 is formed to be open to the front. Accordingly, the upper member 412 and the lower member 414 are formed to extend from the upper side 212 while being spaced apart from each other. Of course, the upper member 412 and the lower member 414 can be deformed into various shapes.

The locking part 420 is in a state in which the upper part is inserted into the holder 410 while the grating 300 is inclined, and then is erected to close the front opening 210, or the slide is inserted in the open side direction of the trench 200. In the state, it serves to prevent the upper portion of the erected grating 300 from being separated from the front of the holder 410.

In addition, the assembly support 430 is formed on the lower side of the holder 410 and in contact with the grating 300, and grating for the holder 410 to guide the grating 300 to be assembled to the trench 200. 300) hinges or supports the slide movement.

In detail, the locking part 420 includes a locking protrusion 422 and a locking protrusion 424.

The locking projection 422 is formed to protrude from the inner upper surface of the holder 410, that is, the lower surface 213 of the upper member 412. In this case, the locking protrusion 422 may be formed to protrude continuously from the upper member 412 along the axial direction of the trench 200, or may be formed to protrude non-continuously. Of course, the locking projection 422 can be deformed into various shapes.

In addition, the locking protrusion 424 is formed to extend to the upper portion of the grating 300. At this time, the locking protrusion 424 is formed to extend upward from the grating 300 so as to correspond to the locking protrusion 422.

Thus, in a state in which the upper rear side of the grating 300 is erected in contact with the lower side of the holder 410, the locking protrusion 424 is caught by the corresponding locking protrusion 422. Accordingly, the grating 300 is prevented from being further rotated to the outside of the trench 200 with the upper portion of the grating 300 erected in the trench 200 and the assembly (installation) is completed, and the lower portion is prevented from being rotated to the outside of the trench 200. 200) is prevented from being inserted into the interior.

Of course, the locking protrusion 424 can be deformed into various shapes.

Meanwhile, the assembly support 430 includes a hinge guide ball 432, a rear arch surface member 434, a stopper 436 and a supporter 438.

The hinge guide ball 432 is provided on the lower front edge of the holder 410, in particular, at the front end or front edge of the lower member 414. And, the hinge guide ball 432 has a spherical shape. Accordingly, some of the circumferential surfaces of the spherical hinge guide ball 432 are integrally connected to the lower member 414.

At this time, the hinge guide ball 432 is located inside the trench 200 based on the line of the trench 200 extending upward from the front surface 214 of the trench 200. In addition, it is assumed that the hinge guide ball 432 is continuously formed along the axial direction of the trench 200.

The rear arch surface member 434 is formed to be curved at least on the rear side of the grating 300 to surround and contact a part of the hinge guide ball 432. The grating 300 serves to guide the slide movement in the rotation and axial direction of the trench 200.

In particular, when the grating 300 is erected and assembled to the trench 200, the rear arch surface member 434 comes into contact with an approximately front circumferential surface of the hinge guide ball 432. For this reason, the workability and decomposition of the grating 300 for the trench 200 are easy.

In addition, the stopper 436 is formed to protrude downward from the lower side of the hinge guide ball 432. Of course, the stopper 436 can be deformed into various shapes.

In addition, the supporter 438 protrudes from the rear surface 211 of the grating 300, and comes into contact with the stopper 436 while the grating 300 is erected with respect to the trench 200.

Thus, the grating 300 is prevented from being inserted into the trench 200 and serves to support and guide the grating 300 that slides with respect to the trench 200.

In addition, the front surface 214 of the trench 200 passes through the inflow expansion hole 215 to increase the inflow amount of rainwater.

In addition, after the grating 300 is assembled in a state erected in the trench 200, at least the lower side is disposed to coincide with the front surface 214 of the trench 200. Accordingly, it is easy to assemble and separate the grating 300 for the trench 200.

In addition, the grating 300 is formed to protrude from the lower side to the front rib 320 in order to prevent foreign matters such as tree branches and the like from blocking the inflow hole 310 and the inflow expansion hole 215. At this time, the rib 320 also serves as a handle. Of course, the rib 320 can be deformed into various shapes.

The inflow expansion hole 215 is formed to be open in the upper direction of the front surface 214 so that the flow resistance of rainwater is reduced. In particular, as the ribs 320 are disposed adjacent to the upper edge of the front surface 214, foreign substances are prevented from leaking between the upper side of the front surface 214 and the lower side of the grating 300.

Meanwhile, rainwater flowing into the inflow hole 310 of the grating 300 and the inflow expansion hole 215 of the front surface 214 flows along the trench 200, and the rainwater flows into the horizontal drainage pipe 30 by the flow velocity. It flows past without entering.

To prevent this, the transverse drainage pipe 30 connected to the open side of the rear surface 211 of the trench 200 extends the inflow guide member 32 at the set edge. At this time, when the transverse drainage pipe 30 is connected to the open side of the rear surface 211, the inflow guide member 32 is inserted into the open side of the rear surface 211 and is located inside the trench 200. So, some of the rainwater flowing along the trench 200 is intensively introduced into the corresponding lateral drainage pipe 30 by the inflow guide member 32, and the remaining rainwater flows from the neighboring lateral drainage pipe 30 along the trench 200. It flows toward the inflow guide member (32).

In particular, the open side of the rear surface 211 of the trench 200 is formed at a height spaced apart from the lower side 213 to prevent or reduce sludge such as mud from flowing into the transverse drainage pipe 30.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is only an example, and those of ordinary skill in the field to which the technology belongs, various modifications and equivalent other embodiments are possible therefrom.
