Description

A drain for a bridge < RTI ID = 0.0 >

The present invention relates to a prefabricated bridge water collecting apparatus, and more particularly, to a prefabricated bridge water collecting apparatus including a drain pipe, a collecting body coupled to an upper end of the drain pipe, and a funnel-shaped collecting pipe inserted and coupled into the collecting body, The present invention relates to a prefabricated bridge water collecting apparatus which provides simplicity of construction and efficiency of drainage compared to a water collecting apparatus.

Bridges are installed on both sides of the road surface in order to drain the rainwater on the road surface of the bridge and the water used for road surface cleaning to the lower part of the bridge. Conventional bridge catches consist of upper catches and lower catches. In order to install the bridge catches, concrete should be poured after making perforations in the part of the concrete that is in contact with the lower catches. As a result, it has been pointed out that there is a problem in the conventional bridge collecting halls such as the difficulty of punching the formwork in the installation process and the difficulty of recycling the formwork.

Several prior arts have been proposed to overcome this problem. One of them has a water collecting port in the form of coupling a funnel-shaped upper collecting port to a drain pipe. The drain pipe has an outer pipe having an inner flange formed at a lower end thereof and an outer diameter corresponding to an inner cavity formed by the inner flange And an inner tube having an outer flange formed at an upper end thereof so that an inner tube inserted into the upper portion of the outer tube is prevented from being caught by the lower end of the outer tube. According to this prior art, there is no need to drill the formwork during the installation of the bridge catcher, and the form can be recycled. However, since the joint between the lower end of the upper catch and the inner pipe of the drain pipe is not combined or closed, water often leaks to the outside through a gap between the lower end of the outer pipe and the upper end of the inner pipe during drainage, The stability of the product is low.

It is an object of the present invention to provide a prefabricated bridge water collecting apparatus, which is constructed in a prefabricated manner, and provides simplicity of construction and efficiency of drainage compared with conventional bridge catchers due to its structural features.

In order to solve the above-mentioned problems, the present invention is characterized by " a drain pipe; A converging portion formed to converge downward at a lower end of the inflow portion and having an inner surface stepped downwardly and having a circular inclined surface at a lower portion of the inflow portion, And a lower pipe portion having an outer diameter and extending downward at a lower end of the converging portion, the lower pipe portion being fitted to the upper end of the drain pipe; And a collecting pipe having a lower portion protruding downward through the drain pipe as a funnel-shaped member to be fitted into a lower portion of a stepped portion of the inner surface of the converging portion of the collector body. .

In this case, a flange portion formed at the lower side of the lower portion of the lower portion of the collector may be provided.

In addition, a groove formed in a ring shape and a sealing member coupled or filled in the groove may be provided on a lower portion of a step of the inner surface of the converging portion of the collector.

Further, the inflow portion of the water collecting body may be provided with a lid holding jaw formed inside.

In addition, a portion of the collector pipe exposed through the drain pipe is provided with a fastening portion for fastening a drain pipe having an inside diameter corresponding to the outside diameter of the collector pipe.

The prefabricated bridge water collecting apparatus according to the present invention has the following effects.

1. It is not only unnecessary to drill formwork when installing the prefabricated bridge water collecting device, but also the length of the drain pipe can be variously adjusted according to the design conditions of the upper slab of the bridge, so that the efficiency and economical efficiency of the bar can be secured.

2. There is no leakage of water during the drainage to the drainage pipe at the lower part of the bridge, so that stable drainage can be achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 and FIG. 2 are respectively an exploded perspective view and a combined sectional view of the assembled bridge water collecting apparatus according to the present invention.

As shown in FIG. 1 and FIG. 2, the assembled bridge water collecting apparatus according to the present invention includes a drain pipe 100, a collector 200, and a collector pipe 300.

The drain pipe 100 is composed of a pipe commonly used for drainage, and the bridge collector according to the present invention is installed in a form as shown in FIGS. 3 and 5, The length of the drain pipe 100 can be varied in various ways.

2, the flange 110 is formed at the lower end of the drain pipe 100. The flange 110 is disposed at a position where the collector pipe 300 is connected to the collector 200 Is prevented from being shaken due to the space between the collector pipe (300) and the drain pipe (100) when the lower part of the inner surface of the convergent part (220) I will. Therefore, it is most preferable that the inside diameter of the flange portion 110 is the same as the outside diameter of the lower portion of the collector pipe 300.

The water collecting body 200 includes an inlet 210 formed to have a hollow space up to a certain depth, a lower portion of the inlet 210 to converge downward, an inner surface of which is stepped downward, A converging portion 220 formed of an inclined surface and a tube extending downwardly at a lower end of the converging portion 220 and having an outer diameter corresponding to an inner diameter of the drain pipe 100, And a lower pipe portion 230 which is connected to the lower pipe portion.

The enlarged view of the portion A in FIG. 3 (FIG. 3) shows a groove formed in a ring shape below the step of the inner surface of the converging portion 220 of the collector 200 and a sealing member (221) are shown. The grooves and the sealing member 221 allow the water collecting pipe 300 to be stably fixed to a lower portion of a step of the inner surface of the water collecting body 200. In the water draining process, And prevents leakage to the space between the water pipes (300).

The inlet part 210 of the water collector 200 is provided with a lid latching protrusion 211 formed on the inside thereof for preventing passage safety and preventing the inflow of the object. It is a configuration for fixing.

3 and 4, it can be seen that the tight contact between the converging part 220 and the water collector 300 and the stable connection between the lower pipe part 230 and the drain pipe 100 A screw connection may be made.

The collector pipe 300 is a funnel-shaped member that is fitted into a lower portion of a stepped portion of the inner surface of the converging portion 220 of the collector 200, and the lower portion protrudes downward through the drain pipe 100.

The water flowing through the inlet 210 of the collector 200 flows into the drainage pipe 400 under the bridge through the collector pipe 300. As described above, Water is leaked into the space between the collector 200 and the collector pipe 300 due to the groove formed in the ring-shaped lower part of the inner surface of the inner surface of the collector 220 and the sealing member 221 coupled or filled in the groove The water introduced into the inflow section 210 is stably guided to the drain pipe 400 at the lower part of the bridge through the lower part of the collecting pipe 300.

As shown in FIGS. 1 and 3, a portion of the collector pipe 300 exposed through the drain pipe 100 is exposed to the outside of the collector pipe 300 It is preferable that the fastening part 310 is fastened to the drain pipe 400 having the corresponding inner diameter. The shape of the fastening part 310 may be a screw groove or the like for screw connection.

The present invention has been described in detail with reference to the preferred embodiments. However, it should be understood that the present invention is not limited to the above-described embodiment, but may be modified and changed without departing from the gist of the present invention. The claims of the present invention thus include such modifications and variations.
