Description

{Drainage System for Use in Bridges}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road facility, and more particularly, to a drainage apparatus for effectively excluding road surface water.

If the road surface such as rainwater or snow melted on the road is not smoothly discharged, the road may be flooded and cause traffic congestion or accidents. Therefore, the drainage performance of the road is very important factor for the safety of the vehicle. Road drainage is particularly problematic in highway bridges where vehicles are driven at high speeds and both sides are blocked by firewalls. Continued improvement is required due to the long-term trend of rainfall patterns, which is increasingly frequent in localized heavy rains.

According to an example of a conventional highway bridge drainage apparatus, a catching port for collecting infiltration water such as rainwater (hereinafter referred to as "rainwater") is formed at regular intervals along the vehicle traveling direction at a position where the bridge slab and the side barrier meet, A horizontal drain pipe is connected to each side of the bridge so as to be inclined to the side of the bridge. The outer end of the horizontal drain pipe is connected to a vertical drain pipe for collecting the rainwater guided through the horizontal drain pipe and guiding and guiding the rainwater in the throttle direction.

Recently, in order to increase the drainage efficiency, there has also been applied a water supply system in which a collector pipe in the shape of a line is provided extending in the longitudinal direction of the bridge instead of a collecting point formed at regular intervals. FIG. 1 shows an example of a prior art watercraft device. The collector pipe 10 is installed along the direction in which the barrier wall 4 extends, that is, the road direction, at the inner lower side of the barrier wall 4 at the position where the bridge slab 2 of the bridge meets the barrier wall 4, (Not shown) extending in the lateral direction are connected to the bridge slab 2 at regular intervals, and a vertical water pipe 30 is attached to the bridge slab 2 by brackets 32 below the outer ends of the lateral water pipes. . 2, the collector pipe 10 includes a pipe body 12 having a rectangular cross section and having an opening 14 opened to the inside of the road, and a pipe body 12 covering the opening. And may include a grating 16 which can be fastened with a screw 19 and in which a plurality of longitudinal through holes 18 are regularly formed.

In such an advanced water system, the road surface water can be quickly and effectively collected into the water collecting pipe 10 through the through holes 18 formed in the grating 16 of the water collecting pipe 10, 30 in the throttling direction. Accordingly, the road surface water can be continuously discharged through the collector pipe 10.

On the other hand, foreign matter such as dust, soil, leaves, or garbage separated from the vehicle may flow into the road surface of the bridge, and the drainage pipe may be clogged due to such foreign matter, and the drainage efficiency may be lowered. Therefore, the brick drainage system requires periodic or irregular cleaning, which is the same not only in the point drainage system but also in the advanced water treatment system shown in Figs. However, the conventional brick drainage system is very inconvenient for the cleaning work, and not only the workability is deteriorated, but also exposes the operator to a great danger due to the road conditions on which the vehicle travels at high speed. 3, the inner edge of the collector pipe 10, that is, the grating 16, is located at a position corresponding to the inner edge of the collector pipe 10, This is because the opening 14 of the collector pipe 10 is very narrow as well as it is difficult to access because it is covered by the grating 16.

In order to remove the foreign matter accumulated in the collector pipe 10, the screw 19 is loosened in each collector pipe 10 formed by a predetermined length unit to separate the grating 16 and the collector pipe 10 is cleaned It is necessary to repeat the operation of tightening the grating 16 again. If the cleaning work is not performed frequently, workability may be further deteriorated because it is difficult to separate the grating 16 due to foreign matter or concrete pieces separated from the road surface. As described above, in the conventional bridge drainage system, it is difficult to perform maintenance work such as cleaning to remove foreign matter, thereby posing a serious threat to the safety of the operator.

On the other hand, in the conventional bridge drainage system, when a flood or heavy rainfall occurs in a state where the collecting or collecting water pipe is once blocked, or when the water is excessively infiltrated, the drainage or the collecting pipe is cleaned and drainage The risk of accidents increases significantly. However, there is no emergency treatment means to recover the drainage function.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and it is an object of the present invention to reduce the amount of foreign matter deposited inside and to facilitate the internal cleaning operation and the maintenance work associated therewith, And it is an object of the present invention to provide a brick drainage apparatus having a reserve drain line that can be activated urgently.

According to an aspect of the present invention, there is provided a brick drainage apparatus including a collecting pipe, a side drain pipe, and a drain pipe. The collector pipe is installed along the extending direction of the barrier wall at an inner lower end of the barrier wall of the bridge. The transverse water pipe is disposed to extend from the water collecting pipe in an outer direction of the bridge and is inclined downward from the water collecting pipe toward the outer side of the bridge to guide the road surface water collected in the water collecting pipe to the outside of the bridge. The vertical water pipe receives the road surface water through the lateral water pipe and discharges the water to the outside.

The collector pipe includes a collector main body having an opening formed in a front side thereof and extending in the lateral direction; A grating disposed in front of the water collector main body to cover the opening and having a plurality of through-holes for receiving the road surface water; First and second link members each having one end connected to the collector main body and the grating and the other end hinged to each other; A cam bar extending rearward from a rear surface of the grating and having a cam pin at a rear end thereof; And a guide plate extending in the front and rear direction in the main body of the water collecting pipe and having a cam hole penetrating through the right and left to accommodate the cam pin and adapted to guide the movement path of the grating.

In one embodiment, the collector pipe may further include an opening / closing handler attached to a front surface of the grating. The opening / closing handler is arranged to extend in the left-right direction on the front surface of the grating, and has an inclined shape that is upwardly moved in the lateral direction.

The opening / closing handler is formed of a plate material extending in the left and right direction, and is curved upwardly in the left and right direction, and may have a convex curve shape when viewed from the front.

Preferably, the road surface drainage apparatus further comprises a preliminary drain pipe selectively providing an additional drainage path between the road surface of the bridge and the vertical drainage pipe. The preliminary drain pipe may have a road surface side end portion connected to the road surface of the bridge and an outer end portion located on the upper side of the longitudinal water pipe, and may be opened or closed by a lid.

Meanwhile, the present invention provides a method for cleaning the brick drainage apparatus. In cleaning the bridging drainage device, first, the bottom side of the opening / closing handler is pushed from the lateral direction by a predetermined tool to raise the grating upward. Then, the inside of the collecting pipe which becomes accessible due to the rise of the grating is cleaned. Then, the opening and closing handler is continuously pushed from the side direction by the predetermined tool, and the grating is lowered to be restored to the original position.

According to the present invention, since the bottom surface of the collecting water pipe constituting the pre-watering device is inclined to the outside, the amount of foreign matter such as dust, gravel, leaves, and garbage deposited on the bottom of the collecting water pipe can be reduced. Accordingly, the burden of the cleaning operation or the maintenance operation can be alleviated.

According to the embodiment, since the grating of the collecting pipe can be easily lifted upward, the accessibility of the inside of the collecting pipe can be improved to facilitate the cleaning work, and the amount of air to be fed into the grating, The workability can be greatly improved.

According to the particularly preferred embodiment, since the bending and restoring of the grating can be performed by using the manual opening / closing apparatus or the opening / closing apparatus using the vehicle, the maintenance workability can be further improved.

As the maintenance work can be done quickly, it is of course also possible that the manpower put into the work is not at risk of an accident.

According to an embodiment of the present invention, since the brick drainage apparatus has a preliminary drainage channel that can be activated only by lid separation, the preliminary drainage line functions before the clogging of the collection pipe is canceled when the concentration pipe is closed in a clogged state The drainage function can be quickly recovered and the risk of accident can be reduced.

In this specification, "front" refers to the direction toward the inside of the bridge for convenience, and "back" refers to the direction toward the outside of the bridge. Due to the opening 112, the front portion can be divided into a front upper portion 114 extending downward from the upper edge and a lower front portion 116 extending upward from the lower edge. The front upper portion 115 may function to support a grating 120 disposed in front of it.

The grating 120 is arranged so as to cover the opening 112 of the collector main body 110 from the front in the assembled state and a plurality of longitudinal through holes 122 are regularly formed.

The opening / closing handler 130 is attached so as to protrude forward from the front surface of the grating 120. In the illustrated embodiment, the opening and closing handler 130 is formed of a plate material extending in the substantially left and right direction, and is curved upwardly in the left and right directions to form a downward convex curve when viewed from the front.

In such an advanced water system, the road surface water can be quickly and effectively collected into the water collecting pipe 10 through the plurality of through holes 122 formed in the grating 16 of the water collecting pipe 10, And the type water discharge pipe 250, and can be discharged. Thus, the road surface water can be continuously discharged through the water collecting pipe 10, the lateral water pipe 200, and the water pipe 250.

7 and 8, the collector pipe 100 further includes a guide plate 140, a cam bar 150, a support bar 160, and a slope plate 170 installed therein .

The guide plate 140 is disposed to face forward from the inner peripheral surface of the back surface portion of the collector main body 110 and is provided at each end of the collector main body 110. In the guide plate 140, a curved cam hole 142 is formed through the left and right sides. At the upper and lower ends of the cam hole 142, there may be formed hooking protrusions extending in the vertical direction.

The cam bar 150 is fixed at the left and right ends of the rear surface of the grating 120 so as to be rearward and the cam pin 152 is provided at the rear end thereof so as to protrude in the direction of the guide plate 140. The cam pin 152 can be fitted into the cam hole 142 of the guide plate 140.

Two support bars 160 may be provided on the left and right sides of the back surface of the grating 120. The support bar 160 extends rearwardly downward from the rear surface of the grating 120 and is inclined downwardly toward the rear. The front end of the support bar 160 is fixed to the bottom of the rear surface of the grating 120, and the rear end of the support bar 160 is rotatably coupled to the slope plate 170. In the illustrated embodiment, the front end of the support bar 160 is spaced apart from the front end of the left and right cam bars 150 inwardly of the collecting pipe main body 110 so that the movement of the support bar 160, So that it is not disturbed by the plate 140.

The slope plate 170 is a plate-like member extending in the left-right direction in the collecting pipe main body 110, and is disposed so as to be inclined downwardly toward the rear. The front ends of the left and right edges of the slope plate 170 are rotatably coupled to the first hinge 172 provided on the back surface of the lower front portion 116 of the collector main body 110, And is hingedly connected to the rear end of each support bar 160 by the second hinge 174. [

The collector pipe 100 may be opened and closed as follows.

6, when an external force acting upward is applied to the grating 120 or the opening / closing handler 130, the external force is applied to the grating 120 through the support bar 160 having the front end fixed to the lower end of the grating 120, Plate 170 and the first and second hinges 172 and 174, respectively. When the external force is continuously applied, the support bar 160 is lifted upward, and the rear end of the slope plate 170 hinged to the rear end of the support bar 160 is likewise heard upward. At this time, the slope plate 170 is rotated counterclockwise about the first hinge 172 in the drawing. The cam pin 152 at the end of the cam bar 150 moves along the cam hole 142 of the guide plate 140 to restrict the upper portion of the grating 120 from moving arbitrarily. As a result, the grating 120 and the support bar 160 are moved in parallel toward the front upper side, and the slope plate 170 is rotated about the first hinge 172 to reach the opened state as shown in FIG. 9 do.

9, when the application of the upward external force to the grating 120 or the opening / closing handler 130 is stopped, the grating 120 is caused to fall downward due to gravity, and the downward force Is transmitted to the slope plate 170 through the support bar 160 so that the slope plate 170 rotates in the clockwise direction around the first hinge 172 in the drawing. The cam pin 152 at the end of the cam bar 150 moves along the cam hole 142 of the guide plate 140 so that the moving direction of the grating 120 is restricted, The support bar 160 moves parallel to the rear lower side, and can return to the state shown in Fig.

FIG. 10 schematically shows a process of constructing a brick drainage apparatus according to the present invention.

In constructing the bridging drainage system, the slab reinforcement to be a skeleton of the bridge slab 60 is installed, and the L-shaped bobbin constituting the preliminary drain pipe 350 is piped (Step 400).

When the piping of the L-shaped bend pipe is completed, the slab concrete is laid with the upper end of the L-shaped bend temporarily blocked, and the bridge slab 60 is constructed (Step 402). When the curing of the bridge slab 60 is completed, it is preferable that the lid 360 is fastened to the preliminary drain pipe 350 to prevent foreign matter from being introduced.

Then, the collector pipe 100 is installed. Then, a drain pipe mounting groove for installing the lateral water pipe 200 is formed (operation 404). First, the slabs 60 are blocked out so that the inclined surfaces are formed at the places where the transverse drain pipes 200 are to be installed. As described above, the bridge slab 60 normally has a plate-like shape that is sloped so that the road surface water flows in the direction of the bridge edge. However, it is preferable that drainage from the collecting pipe 100 to the transverse pipe 200 is made more smooth, It is necessary to secure the inclination of the transverse drain pipe 200 so that foreign matter that can be deposited on the drain pipe 100 can be effectively discharged. For this purpose, it is preferable that the drain pipe mounting groove is sloped through the concrete break.

Then, the side water pipe 200 is mounted on the water pipe installation groove (Step 406). At this time, by joining the lower portion of the lateral water pipe 200 to the bridge slab 60 by the non-shrinkage mortar treatment, the lateral water pipe 200 is pushed laterally or separated during the construction of the barrier wall 70 .

In operation 408, a barrier wall 70 is formed by placing concrete for forming a barrier wall 70 on an upper portion of the collecting pipe 100 and the side water pipe 200.

Thereafter, the fixing bracket 240 is fixed to the outer wall of the bridge slab 60 or the barrier wall 70 at regular intervals using an anchor bolt. Then, the vertical drain pipe 250 is mounted on the fixing bracket 240 (operation 410).

On the other hand, a packing layer 62 may be additionally formed on the bridge slab 60.

The above-mentioned bridge drainage apparatus operates as follows.

The number of roads existing on the road surface of the bridge can be quickly and effectively collected into the collector pipe 100 through the plurality of through holes 122 formed in the grating 120 of the collector pipe 100, 200, a vertical drain pipe 250, and a vertical drain pipe 300, and can be discharged to the outside.

Closing force is applied to the grating 120 or the opening and closing handler 130 so that the grating 120 and the opening and closing handler 130 can be operated to remove foreign substances from the collecting pipe 100 periodically or irregularly 130 are lifted upward. At this time, the slope plate 170 located under the collecting pipe 100 is also turned upside down. Accordingly, the compressed air or the compressed water can be sprayed into the collecting pipe 100 or sucked by the vacuum cleaner, thereby effectively performing the cleaning operation. At this time, the operator may scratch the sediment with his / her hand by hand, or pick up a large foreign object with the forceps. When the cleaning is completed, the external force applied to the grating 120 or the opening / closing handler 130 is released, and the members in the collector pipe 100 such as the grating 120 and the slope plate 170 are returned to their original positions.

According to the present invention, since the slope plate 170 provided at an oblique slope suppresses the accumulation of foreign matter on the bottom surface of the collecting pipe 100 and facilitates the discharge to the rear side, the clogging due to the foreign matter is greatly reduced do. Furthermore, the grating can be easily lifted up and cleaned with ease even for a small amount of foreign matter accumulated in the water collecting pipe 100, so that maintenance workability can be greatly improved.

Meanwhile, if the heavy rain falls or a large amount of road surface exists on the bridge in a state where the water collecting pipe 100 is blocked, the lid 360 of the preliminary drain pipe 350 is removed before restoring the water collecting pipe 100 The preliminary drain can be switched to an operable state. Therefore, even if it takes a considerable amount of time to recover the collecting pipe 100, it is possible to quickly recover the drainage function, thereby greatly reducing the risk of accident caused by the road surface water.

When the grating 120 is removed for cleaning the water collecting pipe 100, the worker may manually apply a force, but this can be done by using a vehicle or other separate device. FIGS. 11 and 12 show a sled apparatus 500 as one embodiment of an apparatus that can be used to remove the grating 120 in this way.

11 and 12, the sled apparatus 500 includes a front portion 502, a top surface 504, and a back portion 506 corresponding to the front, top, and back surfaces of the barrier 70 So as to be able to pass over the upper outer side of the barrier wall (70). The top surface 504 and the inner peripheral surface of the back surface 506 of the sled apparatus 500 are located on the front surface and the top surface of the barrier wall 70, And are spaced apart from the back surface by a predetermined distance. A plurality of rolling wheels 508 are installed on the inner circumferential surface of the sled apparatus 500 to prevent the sled apparatus 500 from directly contacting the barrier wall 70 and colliding with or generating excessive frictional force. The rolling wheels 508 maintain spacing between the sled device 500 and the barrier wall 70 and allow the sled device 500 to easily move along the barrier wall 70 while resting against the barrier wall 70. The sled apparatus 500 has a certain width in the direction in which the barrier wall 70 extends. A foldable handle 510 may be provided at one point outside the sled apparatus 500.

A grating opening and closing tool 550 for lifting up the opening and closing handler 130 attached to the grating 120 of the collecting pipe 100 can be mounted inside the lower end of the front portion 502 of the sled apparatus 500. Fig. 13 shows an embodiment of a grating opening and closing tool 550. Fig. The illustrated grating opening and closing tool 550 includes a support portion 552 extending in the up and down direction and a blade 554 provided at the lower end of the support portion 552. When the grating opening and closing tool 550 is installed, the blade 554 is installed just below both ends of the opening and closing handler 130 of the collecting pipe 100.

When the sled device 500 is placed on the upper part of the barrier wall 70 with the grating opening and closing tool 550 installed and the operator directly pushes the handle 510 or pushes the handle 510 using the work vehicle, The red device 500 moves along the barrier wall 70 and the blade 554 of the grating opening and closing tool 550 pushes upward the force acting on the bottom surface of the opening and closing handler 130 of the collecting pipe 100 .

As the sled apparatus 500 continues to move, the opening and closing handler 130 moves up and down to reach the home position. Accordingly, one operator may perform the cleaning operation while operating the sled apparatus 500, or two workers may perform the operation by sharing the operation and cleaning of the sled apparatus 500, respectively.

As described above, in one embodiment, the length of one of the water collecting tubes 100 is 2 to 3 meters (m), and the height of the collecting tube 100 grating 120 is about 6 centimeters (cm). Therefore, since the grating 120 and the opening / closing handler 130 need to be raised and lowered by about 6 cm while advancing the sled apparatus 500 by 2 to 3 m, a large force is not required. In addition, even if cleaning of several hundreds to several hundreds of the water collecting pipes 100 in the bridge is performed, the grating 120 can be removed and the original phase can be restored simultaneously with the cleaning with the compressed water or the compressed air to complete the cleaning in a short time.

In the above-described embodiment, the structure for removing the grating 120 by lifting and lowering the grating 120 is provided in the collector pipe 100, but in the simplified embodiment, only the slope plate corresponding to the slope plate 170 is provided It is possible. 14 and 15 show a collecting pipe according to this embodiment.

In the collector pipe 100a shown in FIG. 14, the slope plate 170a is disposed so as to be inclined downward toward the rear from the rear upper end of the front lower portion 116 of the collector main body 110. According to this configuration, foreign matter accumulation on the bottom surface of the collecting pipe 100a can be suppressed by the slope plate 170a, and the discharge through the rear side drain pipe can be promoted. Since the accumulation of foreign matter is reduced, the cleaning demand can be reduced and the cleaning frequency can be increased.

The slope plate 170b constitutes the entire rear surface or a part of the bottom surface 116 of the collector main body 110 so that the collector pipe 100a shown in Fig. The configuration is simplified. Other features of the embodiment of FIG. 15 are the same as or similar to those of the embodiment of FIG. 14, so a detailed description thereof will be omitted. have.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.

7 to 9, the front end of the support bar 160 is fixed to the rear surface of the grating 120 and the front end of the slope plate 170 is fixed to the front lower portion 116 of the water collector main body 110. In this case, The rear end of the support bar 160 is hingedly coupled to the rear end of the support bar 160 and the second hinge 174. In another embodiment of the present invention, The positions may be mutually changed. 16 to 18 show such an embodiment.

16 to 18, the collector pipe 100 includes a guide plate 140, a cam bar 150, a support plate 660, a rotation bar 670, Respectively. The support plate 660 is a plate-like member extending in the left-right direction in the collector main body 110. The support plate 660 is inclined downwardly toward the rear, and the front end of the plate is fixed to the lower end of the back surface of the grating 120 have. The rotation bar 670 is rotatably coupled to the first hinge 172 provided at the rear surface of the lower portion of the front surface 116 of the water collector main body 110 and the other end is rotatably supported at the rear of the support plate 660 And is hinged at both ends and the second hinge 174.

6, when an external force acting upward is applied to the grating 120 or the opening / closing handler 130, the support plate 160 having one end fixed to the lower surface of the backside of the grating 120 The external force is transmitted to the pivot bar 170 and the first and second hinges 172 and 174. [ When the external force is continuously applied, the support plate 160 is lifted upward, and the other end of the rotation bar 170 hinged to the rear end of the support plate 160 is likewise heard upward. At this time, the pivot bar 170 is rotated counterclockwise about the first hinge 172 in the drawing. The cam pin 152 at the end of the cam bar 150 moves along the cam hole 142 of the guide plate 140 to restrict the upper portion of the grating 120 from moving arbitrarily. As a result, the grating 120 and the support plate 160 are moved in parallel to the front upper side, and the pivot bar 170 rotates about the first hinge 172 to reach the open state as shown in FIG. 9 do.

9, when the application of the upward external force to the grating 120 or the opening / closing handler 130 is stopped, the grating 120 is caused to fall downward due to gravity, and the downward force The rotation bar 170 is transmitted to the rotation bar 170 through the support plate 160 so that the rotation bar 170 rotates in the clockwise direction around the first hinge 172 in the drawing. The cam pin 152 at the end of the cam bar 150 moves along the cam hole 142 of the guide plate 140 so that the moving direction of the grating 120 is restricted, The support plate 160 moves parallel to the rear lower side, and can return to the state shown in Fig.

Although the opening / closing handler 130 for applying an external force to the grating 120 of the collector pipe 100 has been described above, the opening / closing handler 130 is not necessarily required. For example, if there is no opening / closing handler 130 or a corresponding member, the operator can directly grasp the grating 120 and pull it up or pull it with a separate tool to open the grating 120. It goes without saying that the shape of the opening and closing handler 130 may be different from that shown in the drawings.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. In particular, one or more features of one or more embodiments may be applied to other embodiments either singly or in combination.

In the above description, the collector pipe of the bridge drainage system is installed on the lower side of the barrier wall.
