Description

Double pipe for drainage {DUAL PIPE FOR WATER DRAINING}

The present invention relates to a drainage pipe, and more specifically, it is connected to each floor of an apartment veranda and the like to minimize drainage noise by changing the structure of the drainage pipe to separate the wastewater and rainwater and guide it downward. It relates to a double pipe structure that can be smoothly drained.

Conventional apartments and multi-family houses, such as rainwater from the upper floors of the building or various wastewater, such as wastewater generated in the house is a drain pipe for guiding this to easily descend to the lower floor, and the various kinds of the generated above The inlet portion of the flowing water is installed internally, and the pipes extending from the inlet are interconnected by connecting pipes installed in each interlayer slab to form a drainage pipe.

The drainage pipe used for this purpose is usually molded as PVC material, and different drainage pipes are installed to separate and drain rainwater and wastewater separately, thereby reducing installation and construction costs and work efficiency. It became a factor to let.

On the other hand, in order to improve this, in recent years, the construction cost has been reduced by forming a diaphragm in a single drainage pipe. However, in the case of such a single pipe structure, each drainage channel has a semicircular shape instead of a conventional circular shape. There are some problems.

In other words, due to the irregular shape of the drainage passage, the phenomenon of hitting the inner side of the pipeline was caused by pressing the inflow in the lateral direction, which caused noise. Also, when the water was dropped, the water could not fall along the inner side of the pipeline. As it falls along the space part, it hits the inner wall and falls repeatedly, causing shortening of the pipe life and noise, severe drainage, and bad smell. Residents were uncomfortable and privacy was violated, and there was a problem that the drainage noise of the lowermost part was severely generated by being almost directly from the uppermost part to the lowermost part.

The present invention is proposed to improve the above-mentioned conventional problems, and in providing a pipe structure in which wastewater and rainwater generated at home are guided downward through one pipe, smooth drainage is minimized while minimizing falling noise of running water. The goal is to make it happen.

The above object is a drainage pipe having a plurality of conduits which form rainwater flow paths and wastewater flow paths, respectively, in one pipe main body, wherein the plurality of conduits form a circular shape having the same size in cross section and are connected in parallel to each other. It is provided as, each of the pipelines can be achieved through the double pipe structure for drainage, characterized in that the guide piece for guiding the running water along the inner wall surface is formed in a spiral shape.

1 is a perspective view of the present invention double pipe is cut to a predetermined length.

2 is a plan view of the double pipe;

3 is a cross-sectional view taken along the line AA ′ of FIG. 2.

5: through hole

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows a drain pipe main body 1 according to an embodiment of the present invention, in which a rainwater drainage pipe 2 and a wastewater drainage pipe 3 each have the same circular cross-sectional shape, and have a '8'. It is formed to be connected in the shape of a child.

In particular, a plurality of guide pieces (2a, 3a) for guiding the running water along the inner wall surface of each of the drain pipe passage (2, 3) is formed in a spiral shape, the assembly of the pipes on the inner surface of the drain pipe body (1) In order to improve, the projections 4 were formed at positions facing each other.

In the drawings, reference numeral 5 denotes a through part 5 formed at regular intervals along a circumference to improve noise resistance of the drain pipe main body 1.

The drainage pipe of the present invention, which has such a configuration, is cut to a predetermined length and connected to each floor slab connection pipe (not shown) for construction of the apartment veranda, thereby combining the rainwater drainage channel and the wastewater drainage channel into one pipe. You can install it.

In particular, since the drain pipe of the present invention has two drainage pipes (2, 3) formed therein, it is necessary to accurately match the position between the pipes when connecting the pipes, and this connection work is easily performed through the projection (4). It can be done.

That is, in the slab connecting pipe, a groove portion 4 'into which the projection 4 of the drain pipe 1 can be fitted is formed in a corresponding portion in advance as shown by a virtual line in FIG. By the coupling position between the drain pipe (1) and the slab connector can be made accurately.

In this way, the drainage pipe of the present invention, in which the installation is completed, has a flow-inducing flow because the helical guide pieces 2a and 3a protrude from the inner wall while the drainage pipes 2 and 3 have a circular shape. It will be able to smoothly.

In addition, as described above, since the drain flow is smoothly formed and a double pipe structure is formed to form a space between the drain pipe main body 1 and the drain pipe passages 2 and 3, it is understood that drainage noise due to falling water can be minimized. Can be.

In addition, although specific embodiments of the present invention have been described above, it is obvious that the drain pipe structure of the present invention may be variously modified and implemented by those skilled in the art.

However, such modified applications should not be individually understood from the technical spirit or prospect of the present invention, and other modified embodiments should fall within the appended utility model claims of the present invention.

As described above, the present invention provides a pipe structure in which wastewater and rainwater generated at home are guided downwardly through a single pipe so that a smooth flow of flowing water is achieved and the drainage noise is minimized. The effect is to provide an environment.

Claims (2)
