BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bridge drainage system, and more particularly, to a bridge drainage system for draining water collected on a bridge by rain water or the like in a large bridge to an outside of the bridge.

Bridges installed in rivers or rivers are provided with drainage devices for smoothly draining rainwater on the bridges, such as during rainy weather. 1 is a view showing a part of a conventional bridge that employs such a drainage device.

As shown in FIG. 1, in a typical bridge, a plurality of bridges 20 are equidistantly arranged around the bridges 10 installed on the left and right sides of the rivers, and the upper portions of the bridges 20 are disposed at upper portions of the bridges 20. It has a structure in which a plurality of top plates 30 are installed in the provided chair.

A plurality of water collecting pipes 50 for collecting rainwater, etc., collected on the upper plate are provided below the upper plates 30. Typically, the upper plate 30 has a plate shape in which the rainwater flows toward the collecting pipe 50 so that rainwater is collected in the collecting pipe 50.

The lower part of the collecting pipe 50 is provided with a drain pipe 60 for receiving water flowing out to the lower end of the collecting pipe 50 and draining it outward. The drain pipe 60 is suspended by the suspending device 70 in the lower part of the upper plate 30. The drain pipe 60 is installed corresponding to each top plate 30 one by one. That is, the drain pipe 60 is typically installed between each of the piers 20 corresponding to one under the top plate (30). The drain pipe 60 is disposed to be inclined with respect to the horizontal direction so that water discharged from the collecting pipes 50 flows to the pier 20 side.

Each pier 20 is provided with a drain guide pipe 80 disposed in the standing direction. The upper end of the drain guide pipe 80 is open to the end of the drain pipe 60, and the lower end extends to the lower side of the piers 20. Therefore, the water flowing near the pier 20 through the drain pipe 60 is introduced into the drain guide pipe 80 to be guided to the lower portion of the pier 20, and as a result, the water introduced into the upper plate 30 is pier. Drain into the river at the bottom of 20.

By the way, in the conventional bridge structure as described above, there is a problem that the water introduced on the upper plate 30 can be directly drained into the river to cause environmental pollution. That is, the top plate 30 is usually made of a material containing a large number of environmentally polluting chemicals such as asphalt, in the case of draining the water on the top plate 30 to the river in this way, water containing chemical substances dissolved in asphalt, etc. Long-term and continuous inflow into these streams causes severe environmental pollution.

In order to solve this problem, in recent years, without installing the drain guide pipe 80 in the pier 20, the drain guide pipe 80 is installed only in the vicinity of the shift 10, and the drain pipe 60 is a land shift 10 ), It is forced to extend to the perimeter, so that the drained water does not flow directly into the stream.

FIG. 2 is a view showing a bridge employing a conventional drainage device in which the drainage pipe is extended, and FIG. 3 is an enlarged view of the drainage device of FIG. 2.

The drain pipe 160 extends from the central part of the whole bridge to the alternation 10 side under the bridge upper plate 30. As shown in FIG. Therefore, one bridge is provided with two drain pipes 160 extending from the center portion to both shifts 10. In FIG. 2 only the left half of the bridge is shown.

The drain pipe 160 is suspended below the upper plate 30 by a plurality of suspension devices 70, and in this case, the drain pipe 160 is disposed downwardly toward the shift 10 side so that the drain pipe 160 is horizontal toward the shift 10 side as a whole. It is arranged to be inclined at a predetermined angle with respect to the direction.

An inlet 166 corresponding to the collecting pipe 50 is formed on an upper surface of the drain pipe 160. The inlet 166 is formed in a funnel shape and is open upward, and serves to allow the water discharged after the collection through the collection pipe 50 to flow into the drain pipe 160.

Corresponding to the shape of the drain pipe 160 extending to the alternate 10 side, the drain guide tube 180 is provided only on the alternate 10 side and is not provided to each pier 20. Accordingly, the water flowing into the upper plate 30 is not drained to the pier 20 side but to the drain 10 only. The lower portion of the drain guide pipe 180 installed in the shift 10 is connected to a purifier (not shown), and the drained water is purified by the purifier and then flows into the stream.

As such, the water drained in the vicinity of the alternate 10 is purified through a predetermined purification facility, thereby minimizing pollution of the river.

However, in the case where the drain pipe 160 is extended to the alternate 10 in this way, the length of one drain pipe 160 is longer than that of the case in which the drain pipe 60 is arranged for each upper plate 30 as shown in FIG. 1. It becomes very long and also one drain pipe 160 itself is arranged over several top plates (30). Therefore, when the horizontal expansion or vertical shaking between the upper plate 30 is generated, such expansion or shaking affects the drain pipe 160.

That is, in order to prepare for the case in which the lengths of the top plates 30 are lengthened by thermal expansion in summer, the seam portions of the top plates 30 are spaced a predetermined distance as shown in FIGS. 1 and 2, and the temperature difference between summer and winter is different. As it occurs, the top plate 30 repeats stretching and contracting in the horizontal direction. Therefore, in the structure as shown in FIG. 3, a change in distance between the suspension devices 70 fixed to the upper plate 30 occurs, and at this time, the change in distance due to thermal expansion and the change in length due to thermal expansion of the drain pipe 160 The difference in coefficient of thermal expansion makes them different from each other. Accordingly, the suspension device 70 and the drain pipe 160 are subjected to relative movement with each other in the horizontal direction shown in FIG. 3, and thus there is a concern that the adhesive portion between the suspension device 70 and the drain pipe 160 may be damaged. Will be.

In addition, as the use of the bridge continues, a height change between the upper plates 30 of the bridge may occur due to a difference in downward pressure caused by a vehicle or the like that passes on the bridge. In this case, as the height between the adjacent upper plates 30 changes, one point of the drain pipe 160 moves in the vertical direction to cause a change in the slope of the drain pipe 160. Therefore, the suspending device 70 and the drain pipe 160 are subjected to relative movement with each other in the vertical direction shown in FIG. 3, and therefore, there is a fear that the adhesive portion between the suspending device 70 and the drain pipe 160 may be damaged. Will be.

On the other hand, in order to prevent the force is applied in the horizontal or vertical direction as described above, the drain pipe 160 is simply placed over the suspension device 70 without strongly fixing the drain pipe 160 and the suspension device 70. If only fixed in shape can cause other problems. That is, as the use of the bridge continues, the drain pipe 160 may rotate around its longitudinal axis due to vibrations applied to the surrounding bridges. Referring to FIG. 3, the drain pipe 160 rotates little by little in the rotation direction shown in FIG. 3.

However, when the drain pipe 160 rotates as described above, the inlet 166 on the upper surface of the drain pipe 160 cannot maintain the upward opening state, and thus water discharged through the water collecting pipe 50 is drained. ) Can not flow smoothly to flow into.

As such, by adopting the long length drain pipe 160 disposed over the plurality of top plate 30, the relative movement in the horizontal direction and the relative movement in the vertical direction between the suspension device 70 and the drain pipe 160 is allowed. The coupling structure between the suspension device 70 and the drain pipe 160 may be necessary. In this case, the coupling structure should be a structure capable of preventing rotational movement of the drain pipe 160 itself.

The present invention has been made to solve the above problems, the object of the present invention, even when employing a long length drain pipe arranged over a plurality of top plate relative to the horizontal and vertical direction between the suspension device and the drain pipe It is possible to provide a bridge drainage device having a structure capable of allowing movement and preventing rotational movement of the drain pipe itself.

Bridge drainage apparatus according to the present invention for achieving the above object is disposed along the bridge top plate in the lower portion of the bridge top plate for collecting and draining the water flowing out of the bridge top plate; A suspension device fixed to the bridge upper plate and supporting the drainage pipe under the bridge upper plate; And a stopper part interposed between the drain pipe and the suspension device to prevent rotational movement about the rotation axis in the longitudinal direction of the drain pipe. According to this structure, the rotation of the drain pipe is prevented to maintain a state that the inflow of sewage into the drain pipe smoothly.

Here, the suspension device, a pair of suspension bars each of which is fixed to the upper end of the bridge top plate and extending downward with the drain pipe therebetween; And a support bar interconnecting the lower end regions of the suspension bar and supporting the drain pipe. The support bar is coupled to the suspension bar to be rotatable about its longitudinal direction. In addition, both ends of the support bar are coupled to each other through the suspension bar, and double nuts are installed at both ends of the support bar. As a result, even if the inclination of the drain pipe changes due to the vertical movement of the bridge top plate, damage to the drain pipe and the suspension device is prevented.

The stopper portion has a structure that allows relative movement between the drain pipe and the suspension device in the longitudinal direction of the drain pipe. To this end, the stopper portion is a first stopper member fixed to the drain pipe; And a second stopper member fixed to the support bar, wherein the first stopper member and the second stopper member are coupled to be relatively fixed to each other on the rotational movement direction of the drain pipe. According to a preferred example of such a coupling structure, the second stopper member has a shape of a bar disposed to intersect the support bar, and the first stopper member is disposed to partially surround a portion of the second stopper member. Part has a cylindrical shape.

According to the present invention, the damage of the drain pipe and the suspension device due to the length change in the longitudinal direction of the drain pipe and the bridge top plate and the height change of the bridge top plate is prevented, and the rotation of the drain pipe is prevented.

On the other hand, according to the present invention, there is provided a bridge having a bridge drainage structure of the above structure.

Hereinafter, with reference to the drawings will be described in detail preferred embodiments of the present invention. In the description of each embodiment of the present invention, the same parts as those in the prior art shown in Figs. 2 and 3 will not be described in detail, and only different parts will be described, and the same parts as those in Figs. Quote using

4 to 6 is a view showing the bridge drainage apparatus according to the present invention.

Bridge drainage system according to the present invention comprises a drain pipe 160 and the suspension device (300).

The drain pipe 160 is basically similar in structure to the drain pipe 160 shown in FIG. 2, and is disposed in a horizontal direction along the bridge top plate 30 to collect water flowing out of the bridge top plate 30. It receives from and drains to the shift 80 side. The drain pipe 160 is fixed at one point to the bridge, and thus will be stretched or shrunk by thermal expansion or thermal contraction about the fixed portion. In this case, the object to which the drain pipe 160 is fixed may be the pier 20, the alternating 80, or the bridge upper plate 30.

Suspension device 300 is fixed to the bridge top plate 30, and serves to support the drain pipe 160 in the lower portion of the bridge top plate (30). The suspension device 300 is composed of a pair of suspension bars 310 and one support bar 320.

Suspension bar (310), each upper end is fixed to the bridge top plate 30, and extends downward with the drain pipe (160) in between. Both ends of the support bar 320 are coupled to penetrate the lower end regions of the suspension bar 310, respectively, and double nuts 450 are provided at both ends of the support bar 320, respectively. As shown in FIG. 4, the double nut 450 is installed at each end of the support bar 320 with the suspension bar 310 interposed therebetween. Therefore, four pairs of double nuts 450 are installed at two ends of the support bar 320, respectively.

Double nut 450 is a support bar 320 by preventing the second nut from being separated by the rotation of one nut in a state in which one nut is installed on the support bar 320 in a state that does not touch the suspension bar 310, ) And the suspension bar 310 to maintain a through coupling state. Therefore, by this structure, the support bar 320 can be rotated relative to the suspension bar 310 about the axis of rotation in the longitudinal direction.

Stopper portions 410 and 420 are interposed between the drain pipe 160 and the suspension device 300, and more specifically, between the drain pipe 160 and the support bar 320. The stopper parts 410 and 420 include a first stopper member 410 and a second stopper member 420. The first stopper member 410 is fixed to the drain pipe 160 by welding, and the second stopper member 420 is fixed to the support bar 320 by welding.

The second stopper member 420 has a shape of a bar disposed to intersect the support bar 320, and the first stopper member 410 partially surrounds a central portion in the longitudinal direction of the second stopper member 420. It has a partial cylindrical shape arranged. At this time, the first stopper member 410 is slidable along the longitudinal direction of the second stopper member 420. Accordingly, the first stopper member 410 and the second stopper member 420 are coupled to be relatively fixed to each other in the rotational movement direction about the longitudinal axis of the drain pipe 160, and further, the second stopper member ( On the longitudinal direction of the 420 (that is, the longitudinal direction of the drain pipe 160) is coupled to allow relative movement.

On the other hand, since the support bar 320 is rotatably coupled to the suspension bar 310 about its longitudinal axis of rotation, the second stopper member 420 fixed to the support bar 320 is the support bar 320. Pivoting around the fixation site with).

According to this structure, when the relative movement in the longitudinal direction of the drain pipe 160 between the suspension device 300 and the drain pipe 160 due to the difference in expansion rate between the bridge top plate 30 and the drain pipe 160, the first stopper member 410 ) Slides along the longitudinal direction of the second stopper member 420. In addition, when a vertical position shift between the bridge top plates 30 occurs and a change in the inclination angle of the drain pipe 160 occurs, the support bar 320 coupled with the second stopper member 420 rotates. . Therefore, the damage of the suspension device 300 or the drain pipe 160 due to external force at the portion where the suspension device 300 and the drain pipe 160 contact each other does not occur.

In addition, even if the drain pipe 160 supported by the suspension device 300 receives a force rotating about the rotation axis in the longitudinal direction, the coupling structure between the first stopper member 410 and the second stopper member 420 is used. Rotational movement is prevented. Therefore, the position change of the inlet 166 on the upper surface of the drain pipe 160 is prevented, so that the water collected and discharged from the collecting pipe 50 is smoothly introduced into the drain pipe 160 through the inlet 166. It becomes possible.

As described above, according to the present invention, even in the case of employing a drain pipe extending long to the alternate so as not to cause environmental pollution, when a large change in the length caused by thermal expansion and contraction of the bridge top plate and thermal expansion and contraction of the drain pipe occurs. Edo also has the advantage that no damage to the suspension and drainage pipes.

Further, since the rotational movement of the drain pipe is prevented, the sewage collected in the collecting pipe can be smoothly introduced into the drain pipe.

Although the above has been illustrated and described with respect to the preferred embodiment of the present invention, the present invention is not limited to the above-described specific embodiment and those skilled in the art can be variously modified within the scope of the present invention. Of course, such modifications fall within the protection scope of the present invention described in the claims of the present invention.
