【考案の詳細な説明】 〔産業上の利用分野〕 本考案は例えば宅地内排水枝管を宅地内排水本管に接続
するために用いられる排水桝に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a drainage basin used for connecting a drainage branch pipe in a residential land to a drainage main pipe in a residential land, for example.
従来は第４図および第５図に示すように排水桝（１）は

プ接続口（７）とからなる構成を有するものが提供され
ていた。Conventionally, as shown in FIGS. 4 and 5, the drainage basin (1) is provided with an inspection tube receiving portion (3) at the upper end and a main flow groove (4) at the bottom.
And a pair of main pipe receiving portions (5), (6) that are extended to the left and right of the main body (2) and communicate with the upstream end and the downstream end of the main flow groove (4). ) And a trap connection port (7) which is further extended downward and communicated with the main flow channel (4) by the branch flow channel (8).
上記従来構成にあっては第５図に示すように排水桝
（１）の本管受口部（５），（６）に夫々上流側の宅地

口部（３）には点検筒（13）を接続し、該点検筒（13）
の上端は地面に開口させて蓋（14）にて閉鎖することに
より配管を行なうものである。In the above-mentioned conventional structure, as shown in FIG. 5, the drainage main (9) of the drainage basin (1) is connected to the main outlets (5) and (6) of the drainage basin (1), respectively, and the downstream of the residential land is downstream. Connect the inner drainage main pipe (10), connect the branch pipe (12) to the trap connection port (7) via the U-shaped trap (11) and the pipe joint (15), and connect the inspection tube receiving part (3). The inspection tube (13) is connected to the inspection tube (13)
The upper end of the pipe is connected to the ground and closed by a lid (14) for piping.
しかしながら、上記従来構成においては溢流溝（８）が
本流溝（４）に直交しているので、枝管（12）から排水
桝（１）に流入する宅地内排水のような枝流が本流溝
（４）を流れる本流に直交して合流し、合流点において
枝流の本流上流側への逆流が生じる場合があり、このよ
うな逆流が生じると排水桝（１）内における本流や枝流
の流れが著しく妨げられ、枝流と本流との合流が円滑に
行なわれないことになる。However, since the overflow groove (8) is orthogonal to the main flow groove (4) in the above-mentioned conventional configuration, a branch flow such as drainage in a residential land flowing from the branch pipe (12) into the drainage basin (1) is the main flow. There is a case where the main flow flowing through the groove (4) intersects at right angles, and a backflow of the branch flow to the upstream side of the main flow occurs at the confluence point. When such a backflow occurs, the main flow or the branch flow in the drainage basin (1) may occur. The flow of the branch flow is significantly hindered, and the branch flow and the main flow are not smoothly joined.

トラップ（11）の回動角度が規制を受ける。Further, the U-shaped trap (11) is rotatably attached to the trap connection port (7) of the drainage basin (1), and the U-shaped trap (11) is rotated according to the connecting direction of the branch pipe (12). The branch pipe (12) and the drainage basin (1) can be connected to each other at various positions, but as shown by the dotted line in FIG. 4, the U-shaped trap (11) and the main body of the drainage basin (1) ( The rotation angle of the U-shaped trap (11) is restricted by the interference with 2).

A mainstream groove (4) A is formed on the bottom of a main body (2) A provided with an inspection tube receiving portion (3) A at the upper end, and the upstream end of the mainstream groove (4) A is formed on the left and right of the main body (2) A. And a downstream end of the main pipe receiving portion (5) A, (6) A is connected to the trap connecting port (7) A, and the trap connecting port (7) A is U-shaped.
The character trap (11) is rotatably connected in the horizontal direction, the trap connection port (7) A and the main flow groove (4) A are connected by an overflow groove (8) A, and the overflow groove (8) is connected. 8) A obliquely communicates with the main flow groove (4) A from the upstream side, and the rotation of the U-shaped trap (11) around the trap connection port (7) A causes the drainage basin body (2) A to rotate. In order to prevent the trap connection port (7) A from being interfered with by, the drainage basin (1) A is provided in which the trap connection port (7) A is biased toward the lower upstream side of the main body (2) A.

の逆流が起らない。The drainage basin (1) A of the present invention connects the inspection tube (13) to the inspection tube receiving portion (3) A of the main body (2) A, and the inspection tube (13) has its upper end opened to the ground, A pair of main inlets (5) A,
(6) The upstream main pipe (9) and the downstream main pipe (10) are connected to A respectively, and the U-shaped trap (1
Connect the branch pipe (12) via 1). Branch pipe (12)
The U-shaped trap (11) is horizontally rotated corresponding to the connection position of. The branch flow flowing from the branch pipe (12) into the drainage basin (1) A passes through the U-shaped trap (11) from the trap connection port (7) A of the drainage basin (1) A to the overflow groove (8) A. Was introduced,
From the overflow groove (8) A to the main flow groove (4) A of the drainage basin (1) A
However, the head pressure of water in the U-shaped trap (11) is not exerted in the branch pipe (12). Since the overflow groove (8) A obliquely communicates with the main flow groove (4) A from the upstream side, the branch flow is directed toward the downstream side by the overflow groove (8) A. Since it joins with the branch, there is no backflow of the branch to the upstream side of the mainstream.
またＵ字トラップ（11）をトラップ接続口（７）Ａを中

The connection position with can be adjusted in a wide range, and the degree of freedom of piping is increased. When the U-shaped trap is rotated upstream, it becomes easy to install the drainage basin even in a narrow area.
