配が急な管水路の流速を制御し、管水路の破損を防止で
き。Excessive flow rates can cause pipe wear and damage to fittings or branches. For this reason, in pipes with steep slopes, drops are installed at appropriate intervals to reduce the flow velocity. This invention was made in view of the above circumstances. Its purpose is to control the flow velocity in steeply sloped pipes and prevent pipes from being damaged.
落差工を設置する必要力士なく、落差工の費用の節減を
図り得る流速緩衝管水路を提案するにある。The purpose of the present invention is to propose a flow velocity buffer pipe waterway that does not require the installation of a drop structure and can reduce the cost of a drop structure.

間に導水面が設けてあることを特徴とする。, Means for Solving the Problems The flow velocity buffer pipe waterway of the present invention is constructed by attaching a flow velocity control plate for reducing the water guiding cross-sectional area to a pipe waterway having a steep slope, and the control plate has at least a notch at its lower edge. A water guide surface is provided between the pipe and the bottom of the pipe channel.

ユーム管１．１を継ぎ合せ、その継手部分に流速制御板
２を嵌込み構成されている。FIG. 1 shows an example of this pipe waterway, which is constructed by joining hume pipes 1.1 having a circular cross section and fitting a flow rate control plate 2 into the joint.

御板２はヒユーム管１．１間に取付けた状態において、
管水路の底面。The control board 2 is made of concrete and has a disc shape, and has a water guide surface 3-1 with a circular notch in the center. It has four water guide surfaces 3-2 each consisting of circular arc-shaped notches on the upper and lower sides and on both sides. When this control plate 2 is installed between the fume pipes 1.1,
The bottom of the pipe channel.
上面、両側面に沿う４つの導水面３−２と、中夫の切欠
部の導水面３−１とを形成する。Four water-conducting surfaces 3-2 along the top surface and both side surfaces, and a water-conducting surface 3-1 at the cutout of the core are formed.

い。As shown on the right side of Fig. 1, a flow velocity control plate 2 with the same water guiding surface is provided with a flange 4 having a T-shaped cross section on its outer periphery, and the inner diameter of this flange 4 is dimensioned to allow the fume pipe 1 to be inserted, thereby controlling the flow velocity. The plate 2 may be mounted in the hume tube 1.1 with the inner surface of its flange 4 aligned with the outer circumferential surface of the hume tube 1.

チ程度に押えることが望ましい。The flow rate control plate 2 controls the flow rate by reducing the water guiding area of the pipe channel, and the degree of reduction and the installation interval are determined by taking into consideration the gradient, inner diameter, expected water flow rate, etc. of the water channel. In this case, the water level at the maximum flow rate is 80% of the vertical dimension of the pipe channel.
It is desirable to press it to about 0.

水面が形成しであるのでスラッジの沈積が起らない。Functions and Effects The pipe channel constructed as described above does not require the installation of a drop even if the slope is steep as shown in Figure 6, and the flow velocity is controlled to prevent excessive flow velocity from occurring. Damage to waterways can be prevented. Further, since the water guide surface is formed by the notch 3-2 along the bottom surface of the pipe channel, sludge does not accumulate.
