Abstract

(57) [Abstract] [Purpose] The present invention aims to install the drainage basin so that the orientation of the drainage basin is correct. [Arrangement] An arrow 17 is attached from the upstream side to the downstream side at the center of a flow passage 16 connecting an upstream pipe connecting portion 14 and a downstream pipe connecting portion 15 of a main body 12 of a drainage basin 11.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drainage basin adapted to a pipe having a slope.

[0002]

[Prior art]

 As shown in FIG. 2, for example, an inspection pipe connection part (3) is formed on the upper part of the main body (2) of the drainage basin (1), and an upstream pipe connection part (4) is formed on the side surface of the main body (2). A downstream pipe connection (5) is formed. When such a drainage basin (1) is used for a pipe having a slope, a gradual slope is provided from the upstream pipe connecting portion (4) to the downstream pipe connecting portion (5). However, if the gradient from the upstream side to the downstream side is small, it may be difficult to judge whether it is upstream or downstream, so there is a risk of incorrect joining. Therefore, conventionally, as shown in Fig. 3, the upstream pipe connection part (4) and the downstream pipe are connected. Arrows (6, 7) were attached to the outer circumference of the connection part (5) to serve as an index for distinguishing upstream and downstream.

[0003]

[Problems to be solved by the device]

 In the above conventional configuration, the arrows (6, 7) are attached to the outer circumference of the upstream pipe connection part (4) and the downstream pipe connection part (5) of the drainage basin (1). There is a risk that the arrows (6, 7) will come off, and in the case of engraving, the die for molding the drainage basin (1) must be provided with an arrow engraved portion in advance, which reduces the die manufacturing cost. It is higher by that amount, and it takes time and effort to engrave an arrow after molding the drainage basin (1). Further, after the pipes are buried, the arrows (6, 7) are buried in the soil and cannot be seen, so it is impossible to determine whether or not the drainage basin (1) is installed in the correct direction after the pipes are buried.

[0004]

[Means for Solving the Problems]

 As a means for solving the above-mentioned conventional problems, the present invention provides a main body (12), an inspection tube connecting portion (13) formed on the upper part of the main body (12), and a side surface of the main body (12). It is composed of an upstream pipe connecting part (14) and a downstream pipe connecting part (15), and a slope gradually decreasing from the upstream pipe connecting part (14) to the downstream pipe connecting part (15) is provided. A drainage basin (11) provided with an arrow (17) from the upstream side to the downstream side is provided in the central portion of the flow path (16) in the main body (12).

[0005]

[Action]

 In the case of the present invention, the flow path (16) in the main body (12) of the drainage basin (11) is provided with an arrow (17) from the upstream pipe connecting portion (14) side toward the downstream pipe connecting portion (15) side. Therefore, even if the arrow (17) is formed by printing, it does not fall off during storage and transportation, and the arrow (17) is clearly visible from the inspection tube connection part (13) of the main body (12). I can. Further, the arrow (17) can be seen from the inspection tube even after the pipe is buried.

[0006]

【Example】

 The present invention will be described with reference to an embodiment shown in FIGS. 1 and 2. An inspection tube connection part (13) is formed on an upper part of a main body (12) of a drainage basin (11), and an inspection tube connection part (13) is formed on the main body (12). An upstream pipe connecting portion (14) and a downstream pipe connecting portion (15) are formed on the side surface, and a flow passage (16) is recessed from the upstream to the downstream in the bottom of the main body (12). An arrow (17) is attached to the central portion of the channel (16) from the upstream side to the downstream side by printing, stamping or the like.

The drainage basin (11) is formed with a slope that gradually decreases from the upstream pipe connecting portion (14) to the downstream pipe connecting portion (15), and from the inspection pipe connecting portion (13) to the main body (12). Look upstream and identify the upstream and downstream with the arrow (17), install the drainage basin (11) in that direction, and connect the upstream pipe (18) and the downstream pipe (19) respectively to the upstream pipe connection ( 14) and the downstream pipe connection (15).

[0008]

[Effect of device]

 Therefore, in the present invention, the arrows for distinguishing upstream and downstream attached to the drainage basin do not fall off during storage and transportation, so that the drainage basin can be installed in the correct direction even when the gradient from upstream to downstream is small, and the piping The direction of the drainage basin can be checked from the inspection port even after burial.
