Description

Drain apparatus for bridge "

The present invention relates to a drainage device for bridges.

The present invention relates to a drainage device for draining rainwater or cleaning water accumulated on the upper surface of a bridge upper slab to a lower portion of a slab, and more particularly to a drainage device for a bridge capable of easily constructing a drainage device irrespective of the thickness of an upper slab layer .

The contents described in this section merely provide background information on the embodiment of the present invention and do not constitute the prior art.

Fig. 1 shows a cross section of a bridge and a conventional collecting pipe.

Bridges consist of bridges that support loads as bridges, and bridges (2) that form the passages as upper structures of bridges. The upper plate 2 is generally composed of a concrete slab 3 and an asphalt layer 4 packed in the upper part of the slab. A curb and a barrier wall 1 are installed on both sides of the upper plate 2. As a result, the upper surface of the upper plate 2 becomes structured such that when it is raining or the bridge is cleaned with water, the water becomes high. Therefore, a drainage device for discharging water to the lower portion of the bridge should be provided in the upper plate 2.

The drainage device installed in the bridge includes a collector pipe (10) formed to penetrate the upper plate and a drain pipe connected to a lower portion of the collector pipe. The drain pipe is connected to the water pipe or pipe.

The water collecting pipe 10 functions as a drainage port, and generally has a wide upper part and a narrow lower funnel shape. The upper portion of the water collecting pipe is provided with a filtering net to prevent clogging of the collecting pipe or the drain pipe, and the upper portion of the collecting pipe can be formed in a rectangular shape for easy installation of the filtering net.

The slab that forms the roof of the bridge is constructed by installing a mold on the lower part, installing a water pipe, placing reinforcing bars, and placing concrete on the formwork.

However, even if one roof is formed depending on the position of the bridge, the thickness of the slab or the concrete layer can be formed differently, which makes it impossible to use a uniformly sized collecting pipe.

More specifically, a hole for inserting a lower portion of the collecting pipe into a mold is formed, and a lower portion of the collecting pipe is inserted into a form hole to fix the upper surface of the collecting pipe to the road surface to be fixed, After the concrete is poured, the formwork is removed and the collector pipe exposed to the bottom is cut.

That is, since the thickness of the slab layer is not uniform and the collector pipe having a long length is used, it is necessary to process the form to fit the diameter and the installation position of the collector pipe and to cut the collector pipe.

The drain pipe is connected to the bottom of the water collecting pipe and is bolted to the inner pipe so as to cross the inner pipe at the outer periphery of the inner pipe extending to the bottom of the collecting pipe.

In this type of connection, there is a problem that foreign matter is caught by the bolt which is coupled to cross the inner pipe and drainage is not smoothly performed.

The present invention has been made in order to solve the above problems, and more particularly, it is an object of the present invention to provide a drainage device for bridges that can be easily installed because it is not necessary to pre- .

It is another object of the present invention to provide a drainage device for bridges that can drain water smoothly and firmly fix the drainage pipe.
