Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage basin adapted to a sloped pipe.

[0002]

2. Description of the Related Art As shown in FIG. 2, for example, a check tube connecting portion (3) is formed at an upper portion of a main body (2) of a drainage basin (1), and an upstream pipe connection is formed on a side surface of the main body (2). (4), downstream pipe connection (5)
Are formed. When such a drainage basin (1) is used for a sloped pipe, the slope is gradually reduced from the upstream pipe connection (4) to the downstream pipe connection (5). However, when the gradient from the upstream side to the downstream side is small, it is difficult to judge whether it is upstream or downstream. Since there is a possibility of erroneous joining, conventionally, as shown in FIG.
Arrows (6, 7) are attached to the outer circumference of the downstream pipe connection part (5), and are used as indicators for distinguishing upstream and downstream.

[0003]

[Problems to be Solved by the Invention] In the above conventional construction, arrows (6, 7) are attached to the outer periphery of the upstream pipe connection (4) and the downstream pipe connection (5) of the drainage basin (1). The arrow (6, 7) may fall off during storage and transportation in printing, etc.,
In the case of engraving, the mold for forming the drainage basin (1) must be provided with an arrow engraved part in advance, which increases the mold manufacturing cost. When engraving, it takes time to engrave. After the pipe is buried, the arrow
Since (6,7) is buried in the ground and cannot be seen, it is impossible to determine whether the drainage basin (1) is installed in the correct direction after piping.

[0004]

According to the present invention, as a means for solving the above-mentioned conventional problems, a main body (12) and a main body (12) are provided.
Inspection tube connection (13) formed at the top of
It consists of an upstream pipe connection (14) and a downstream pipe connection (15) formed on the side surface of 2), and the slope gradually decreases from the upstream pipe connection (14) to the downstream pipe connection (15). Is provided,
A drainage basin (11) provided with an arrow (17) from the upstream side to the downstream side is provided at the center of the flow path (16) in the main body (12).

[0005]

[Function] In the case of the present invention, the flow path in the main body (12) of the drainage basin (11)
(16) is marked with an arrow (17) from the upstream pipe connection (14) side to the downstream pipe connection (15) side, so even if the arrow (17) is formed by printing, it can be stored and transported. It does not flake off inside and the arrow (17) is clearly visible from the inspection tube connection (13) of the body (12). Further, even after the pipe is buried, the arrow (17) can be seen from the inspection tube.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment shown in FIGS. 1 and 2. In the upper part of a main body (12) of a drainage basin (11), a check tube connecting portion (13) is formed. An upstream pipe connection part (14) and a downstream pipe connection part (15) are formed on the side of (12), and a flow path (16) is recessed from the upstream to the downstream at the bottom of the main body (12). An arrow (17) is provided at the center of the flow path (16) from the upstream side to the downstream side by printing, stamping, or the like.

The drainage basin (11) has a gradually decreasing slope from the upstream pipe connection (14) to the downstream pipe connection (15). Peek Arrow (17)
The drainage basin (11) is set in accordance with the direction, and the upstream pipe (18) and the downstream pipe (19) are respectively connected to the upstream pipe connection part (14) and the downstream pipe connection part (15). And connect to.

[0008]

[Effect of the Invention] Therefore, in the present invention, the arrows for distinguishing the upstream and downstream attached to the drainage basin do not fall off during storage, transportation, etc., so that the drainage basin is correctly oriented even when the gradient from upstream to downstream is small. It can be installed, and even after the pipe is buried, the direction of the drainage basin can be checked from the inspection port.
