Description

Drain pipe system for bridge and its construction method {Drain-pipe for Bridge And Construction Process thereof}

This technology is about a drainage pipe system that improves the durability of bridges from rainwater and is easy to maintain.

In general, a drainage channel is formed on the slab side of a bridge so that rainwater, etc., can be easily discharged. If the drainage facility of the bridge does not function properly, traffic accidents may occur due to flooding of the bridge (road) surface. In addition, due to the increase in the dead weight of the drain pipe, some drain pipe connections may fall off, which can lead to a serious safety accident.

In other words, the efficiency of bridge drainage is reduced due to bending of bridge drain pipes and blockage of connections, and maintenance is difficult, so improvement of bridge drainage facilities is required.

Drainage channels applied to most bridges introduced so far usually perforate the slab of the bridge and embed a drain pipe in the longitudinal direction of the slab, so that rainwater from the bridge is collected through the perforated part of the slab and the drain pipe and then discharged to the lower part of the bridge. It is normal.

According to the prior art, Domestic Patent No. 10-0889995, 'Bridge drain pipe and its construction method', structurally reduces damage to the slab to increase durability and improve maintenance and repair work.

However, as shown in Figures 1 and 2, the drainage system of the existing bridge, which drills the slab 11 and embeds a drain pipe in the perforated part, not only structurally causes the durability of the slab to deteriorate, but also causes the protective wall ( In particular, the problem of shape deformation at the inlet side of the drain pipe 20 occurs due to the load of 13).

In addition, when the drain pipe 20 is blocked by foreign substances such as soil and sand that have flowed in from rainwater, drainage cannot proceed smoothly. Even when trying to clean the inside of the drain pipe, the blocked part cannot be found from the outside, making maintenance and inspection work very inconvenient. In order to compensate for this, there is a problem that the slab must be damaged and then a slab including a drain pipe must be formed again, which may result in higher maintenance costs than necessary.

Hereinafter, the bridge drainage system (hereinafter simply referred to as 'drainage system') will be described in detail with reference to the attached drawings.

First, as shown in Figures 3 and 4, the drainage system 1 according to the present invention largely includes a drainage enclosure member 100, a lateral drain pipe member 200, and a vertical drain pipe member 300, as described above. Through the organic combination of components, the durability of the drainage system (1) is maintained and the advantage of easily removing foreign substances contained in incoming rainwater is realized.

In more detail, the drain enclosure member 100 is installed on the bridge 10 in communication with the lateral drain pipe member 200 to be described later, as shown in FIGS. 5A and 5B, and is located on the surface of the slab 11. It is configured to collect rainwater flowing into the cross section and provide it to the horizontal drainage pipe member 200, and includes a drainage enclosure 110, an extension pipe 120, and a net 130.

For example, as shown, the drain enclosure 110 is formed into the shape of a hollow enclosure using a steel material that is durable against corrosion, and the open lower part is integrally formed to communicate with the upper end of the extension pipe 120.

At the open upper part of the drain enclosure 110, grouting 115, which is entirely in the shape of a plate, is rotatably coupled to the drain enclosure 110 through a hinge, etc. to enable internal opening and closing, and the grouting 115 One or more first through-holes 117 are perforated on the outer surface so that rainwater flowing in from the surface of the slab 11, that is, the surface of the asphalt layer 11a through which the vehicle moves, passes through the first through-hole 117 into the drainage box. (110) Allow for internal collection.

Here, as shown, the first through hole 117 formed in the grouting 115 is shown in the shape of a long hole, but it is not limited to this and any shape that can filter out foreign substances contained in rainwater to some extent can be used. .

In addition, an insertion groove 113 for detachably inserting the net 130 is formed on the side of the drain enclosure 110, and a second through hole is formed on the outer surface of the drain enclosure 110 opposite the insertion groove 113 ( Rainwater flowing into the concrete layer (11b) formed through perforation and having a laminated structure below the asphalt layer (11a) also passes through the second through hole (111) with foreign substances filtered out by the net (130). It is possible to satisfy a structure in which rainwater flows into the drainage enclosure 110 through the above-described first through hole 117 and is supplied to the horizontal drainage pipe body 210 through the extension pipe 120.

To elaborate, the asphalt layer (11a), which is generally installed to have a predetermined thickness at the top of the slab (11), has the property of absorbing some of the moisture, and this absorbed moisture is separated from the bridge (10) by a separate structural layer to be discharged to the outside. Since the features are not provided, it may cause the durability of the bridge 10 itself to be reduced.

Accordingly, in the present invention, not only the rainwater existing on the surface of the asphalt layer (11a), but also the rainwater that flows into the asphalt layer (11a) or the concrete layer (11b) formed to have a laminated structure below the asphalt layer (11a) is treated. It satisfies the structure in which all water flows into the inside of the drainage enclosure 110 through the first through hole 117 and the second through hole 111, thereby preventing the durability of the bridge 10 from deteriorating as it is discharged to the outside of the bridge 10. This happens (see Figure 4).

For this purpose, the upper surface of the drainage enclosure 110 equipped with the grouting 115 in the present invention is exposed to the outside of the bridge 10 so as to face the sky, but is installed lower than the surface of the asphalt layer 11a, and the drainage enclosure 110 ) The side is inserted and installed inside the slab (11) so that it can be included in the cross-section of both the asphalt layer (11a) and the concrete layer (11b), so that rainwater is drained through both the first through hole (117) and the second through hole (111). Ensure that inflow can be easily implemented.

In addition, as shown, the extension pipe 120 is formed in the shape of a pipe (PIPE) with the upper and lower ends open, and the upper part is inserted through the inside of the slab 11 to communicate with the inside of the drainage enclosure 110, and the lower part is The slab 11 is exposed to the outside and is installed in communication with the open upper part of the horizontal drain pipe 210.

Thus, it is possible to supply rainwater flowing into the drainage enclosure 110 to the horizontal drainage pipe body 210 so as not to affect the slab 11.

In addition, the net 130 is detachably coupled to the above-mentioned insertion groove 113, but is installed in the drainage enclosure 110 so that the outer surface faces both the asphalt layer 11a and the concrete layer 11b, and the second through hole ( 111) so that foreign substances contained in rainwater flowing in can be filtered.

For this purpose, the net 130 is formed in the shape of a mesh (MESH), and the upper part satisfies a structure exposed to the outside through the upper surface of the slab 11, so that the net is formed without separating the drainage enclosure 110 from the slab 11. Maintenance of (130), that is, cleaning of filtered foreign substances, is made possible.

In addition, as shown in FIGS. 6 to 8, the lateral drain pipe member 200 is easy to maintain and transfers rainwater flowing into the above-described drainage enclosure member 100 to the vertical drain pipe 310, which will be described later. The configuration for this includes a horizontal drain pipe 210, a clean door 220, and a viewing window 230, and a plurality of them are installed adjacent to each other in the longitudinal direction of the slab 11.

For example, as shown, the horizontal drainage pipe body 210 is made of the same material as the above-described drainage enclosure 110 and has the shape of a hollow enclosure with one side open extending in the direction of the vertical drainage tube body 310 as well as the upper part. is molded into

A flange 211 is formed at the open top of the horizontal drainage pipe body 210 for fastening and fastening to the lower surface of the slab 11 by fastening means (P) such as bolts or anchors, through which the horizontal drainage pipe body ( 210) is installed to be exposed to the outside of the bridge 10, thereby facilitating maintenance.

At this time, as shown, the bottom surface 213 of the lateral drainage pipe body 210 is formed to have an inclination toward the vertical drainage pipe body 310 to remove foreign substances contained in the rainwater transported to the vertical drainage pipe body 310. It is desirable to allow it to be transported together.

In addition, the clean door 220 is rotatably installed on one of a pair of sides of the horizontal drainage pipe body 210 using a hinge, etc., so that the inside of the horizontal drainage pipe body 210 can be opened and closed. On the other side, a viewing window 230 made of a transparent synthetic material is formed to visually inspect the inside of the horizontal drainage pipe 210 through an external lens.

Through this, the worker determines the internal state of the lateral drainage pipe 210 (for example, the extent to which foreign substances are adhered to the floor) through the viewing window 230 from the outside of the bridge 10, and then opens the clean door 220. By opening it, maintenance inside the horizontal drainage pipe 210 can be easily performed.

On the other hand, as shown in Figures 9 and 10, the horizontal drainage pipe member 200 in the present invention is formed on the horizontal drainage pipe body 210 to filter out foreign substances contained in rainwater transferred to the vertical drainage pipe body 310. It may further include a foreign matter catching portion 240 including a retaining plate 241, a retaining protrusion 243, and a retaining space portion 245.

As shown, the retention plate 241 has one end connected to the bottom surface of the horizontal drain pipe 210 or has a separable connection structure, but a plurality of bent portions are formed in the longitudinal direction to have an overall curved shape to form the retention plate ( 241) A residence space 245 is formed on the inside.

At this time, the other end of the retention plate 241, which is formed into a curved shape, is bent so as to be opened at a predetermined distance from the bottom surface 213, flows into the lateral drain pipe 210, and then is transferred to the vertical drain pipe 310. The rainwater is swirled in the retention space 245 and stays there for a certain period of time so that foreign substances, such as sand, fall, and then is supplied to the longitudinal drain pipe 310 or another adjacent retention plate 241. It is desirable.

A plurality of blocking protrusions 243 are formed on the inner surface of the retention plate 241 in the longitudinal direction so as to protrude in the direction of the retention space 245 to prevent foreign matter from forming during the vortex of rainwater flowing into the retention space 245. This structure ensures that the water is filtered by the blocking protrusion 243 and flows into the longitudinal drain pipe 310.

Furthermore, the horizontal drain pipe body 210 in which the foreign matter catching portion 240 is formed opens the clean door 220 formed on the side of the horizontal drain pipe body 210 for maintenance to remove foreign substances caught in the catching protrusion 243. It is possible to perform cleaning by doing so, but preferably, the bottom surface 213 of the horizontal drain pipe 210 is opened so that the entire foreign matter catching portion 240 formed in the longitudinal direction of the bottom surface 213 is exposed to the outside. exposed so that cleaning can be carried out.

That is, as shown, one side of the bottom surface 213 of the horizontal drainage pipe body 210 is rotatably coupled to the horizontal drainage pipe body 210 similar to the coupling structure of the clean door 220, so that the rotation is performed. Through this, the entire foreign matter catching portion 240 satisfies the structure of being exposed to the outside, thereby providing convenience of maintenance.

At this time, the retention plate 241 in the present invention is formed to have different lengths so that the height of each retention plate 241 can be applied equally in response to the slope of the bottom surface 213, so that the longitudinal drain pipe body 310 ) direction, it is desirable to gradually increase the width of the retention space 245, thereby maximizing the effect of filtering out foreign substances without interfering with the transport of rainwater.

In addition, as shown in FIGS. 3 and 4, the vertical drain pipe member 300 is configured to collectively collect and discharge rainwater in which foreign matter has been filtered supplied from the plurality of lateral drain pipe members 200 described above. Includes a longitudinal drain pipe 310 and a bracket 320.

For example, as shown, the vertical drain pipe body 310 is formed in the shape of a hollow box with an open top using the same material as the above-described drain box 110, and the open top is that of the lateral drain pipe body 210. It is installed to be exposed to the outside of the bridge 10 so as to communicate with the open side.

The vertical drain pipe 310 is formed to have a length corresponding to the length of the bridge 10 so that all rainwater discharged from the plurality of lateral drain pipes 210 installed on the bridge 10 can be collected and discharged in one direction, The sides and bottom satisfy the structure supported by the bracket 320.

Here, as shown, the bracket 320 is formed integrally to support both sides and the lower surface except the open upper part of the longitudinal drain pipe 310, or is a combination between a plurality of frames having length in the vertical and horizontal directions. It is formed through, and fastening means (P) are fixedly installed on the outer surface of the slab (11) to support the longitudinal drain pipe body (310).

At this time, a plurality of brackets 320 are fixed to the slab 11 adjacent to each other in the longitudinal direction corresponding to the length of the longitudinal drain pipe body 310, so as to stably support the longitudinal drain pipe body 310. It is desirable.
