Abstract

In the conventional rainwater discharge chamber of the combined sewage system, the floating contaminants introduced into the sewage pipes do not flow into the collection pipe in rainy weather, but flow out into the public waters, which is one of the causes of water pollution in public waters. In the vortex type water level control device for drainage apparatuses of the present invention, the height of the overflow wear 1 is at least between the opening of the inflow pipe 2 and the opening of the collecting pipe 3 in the rainwater discharge chamber of the combined sewer. Install the control panel 6 with higher height. Further, a guide wall 7 is provided between the opening of the inflow pipe 2 and the overflow wear 1 along the overflow wear to at least have a height higher than the height of the overflow wear 1.

Vortex Water Level Control for Drainage

Description

WATER SURFACE CONTROL DEVICE FOR DRAINAGE SYSTEM}

The present invention relates to a vortex type water level control device for drainage, in particular, a control for controlling the water surface in a rainwater discharge chamber (fountain manhole) that fractionates sewage and rainwater in a drainage device for merging rainwater and wastewater. Relates to a device.

5A and 5B respectively show a plan view of a conventional rainwater discharge chamber of the combined sewer, FIG. 6A and FIG. 6B show an ordinary state of the rainwater discharge chamber of the combined sewer of FIG. 5A, and FIG. The inflow pipe opened, 3 is the collecting pipe opened in the side wall, 4 is the discharge pipe opened in the side wall, 1 is the opening of the said inflow pipe 2, and the opening of the collection pipe 3 is the said discharge pipe. Overflow wear having a height higher than that of the discharge pipe 4 provided in the rain discharge chamber 4 to partition the opening of the discharge pipe 4, and floating debris flowing from the inflow pipe 2 to be. 7A, 7B, 8A, and 8B are similarly in a rainy state of the rainwater discharge chamber of the combined sewer in Fig. 5A.

In the conventional rainwater discharge chamber shown in FIG. 5A, all of the sewage including the contaminants 5 is introduced from the inlet pipe 2 into the collecting pipe 3 as shown in FIGS. 6A and 6B, and then, to the sewage treatment plant and the pump station. Inflow. 7A and 7B, the rainwater flows into the excellent discharge chamber together with the sewage, and when the quantity exceeds a certain amount, as shown in FIGS. 8A and 8B, the inflow pipe 2 and the discharge pipe 4 are shown. Overflow of the overflowware 1 interposed therebetween, and a part of the sewage including the contaminant also flows out through the discharge pipe 4 to the public water body (公共 用 水域).

As described above, in the conventional rainwater discharge chamber, the floating contaminants 5 flowing in do not flow into the collecting pipe 3 in rainy weather, but are discharged into the public water through the discharge pipe 4 so that water pollution of the public water is ) Is the cause. One of these factors is the repair characteristic at the time of rain in the conventional rain discharge chamber. In the conventional rainwater discharge chamber, as shown in Figs. 6A and 6B, a surface gradient is usually formed from the inflow pipe 2 toward the collection pipe 3, so that the floating contaminants 5 flow into the collection pipe 3 by flow. The whole amount flows in. However, in rainy weather, as shown in Figs. 7A and 7B, the collection pipe 3 is submerged, and the water surface near the entrance of the collection pipe 3 rises, and the collection pipe (from the inflow pipe 2 as usual) ( There is no water gradient towards 3). In this state, the floating fines 5 do not flow into the collecting pipe 3 but remain in the rain discharge chamber. In addition, if the quantity of inflow into the storm discharge chamber increases and the water depth in the storm discharge chamber exceeds the height of the overflow wear 1, the overflow overflow 1 is overflowed from the inflow pipe 2 as shown in FIGS. 8A and 8B. A water surface gradient directed to the discharge pipe 4 is formed. At this time, the floating contaminants 5 are almost completely outflowed to the public water through the discharge pipe 4 by the flow.

As a means for solving such a problem, it is necessary to generate a flow which is likely to float in the floating pipe 5 into the collecting pipe 3 in the rain discharge chamber. It is necessary to reduce the outflow to the water body.

The vortex type water level control device for drainage apparatus of the present invention has a control panel in which the height provided between the opening of the inflow pipe and the opening of the collection pipe in the rainwater discharge chamber of the combined sewer is at least higher than the height of the overflow wear. do.

In addition, the vortex type water level control device for drainage apparatus of the present invention has a guide wall in which the height installed along the overflowware between the opening of the inflow pipe and the overflowware is at least higher than the height of the overflowware. It is characterized by.

EMBODIMENT OF THE INVENTION Hereinafter, the Example of this invention is described by drawing.

In the present invention, as shown in Figs. 1, 2A and 2B, the vertical control panel 6 is interposed between the opening of the collecting pipe 3 and the opening of the inflow pipe 2 so as to block both. do. It is preferable that the lower end of the vertical control panel 6 be higher than the upper surface of the opening of the collecting tube 3 so as not to impede the drop of clear everyday sewage, but from the upper surface of the opening of the collecting tube 3. It may be low. The upper end of the vertical control panel 6 is preferably higher than the upper surfaces of the openings of the overflowware 1 and the inflow pipe 2, but may be lower than the upper surface of the opening of the inflow pipe 2.

Since the vortex type water level control device for drainage apparatus of the present invention has the above configuration, as shown in FIGS. 1, 2A, and 2B, in rainy weather, the inflow pipe between the vertical control panel 6 and the overflowware 1 is provided. The flow which passed from (2) toward the collection tube 3 forms a vortex on the back surface (the collection tube 3 side) of the vertical control panel 6, and the floating contaminant 5 is collected by the flow. Almost all flow into the pipe (3).

In addition, when the amount of inflow into the rainwater discharge chamber increases and the water depth in the rainwater discharge chamber exceeds the height of the overflowware 1, the inflow pipe 1 overflows as shown in FIGS. 1, 2A, and 2B. A water surface gradient from the opening of (2) to the opening of the discharge pipe 4 is formed.

In addition, when the quantity increases, the force of the surface flow toward the discharge pipe 4 becomes large, and most of the floating contaminants 5 flow out of the overflow wear 1 to the discharge pipe 4 by flow, Since this flows into the collecting pipe 3, it causes a case where the collecting effect is not sufficient.

Therefore, in another embodiment of the present invention, as shown in Figs. 3a, 3b and 4, the lower end is disposed somewhat downward from the upper end of the overflow wear (1), the upper end is the opening of the inlet pipe (2) The sidewalls of the guide wall 7 higher than the upper surface of the upper surface and the upper end of the overflowware 1 and between the opening of the overflowware 1 and the inlet pipe 2 are substantially parallel to the side surface of the vertical control panel 6. Install it if possible.

According to this embodiment, when the water depth in the rain discharge chamber exceeds the height of the overflow wear 1 in rainy weather, the water surface rises in the vicinity of the guide wall 7 as shown in FIG. The water surface gradient from the opening of (2) to the overflow wear 1 is not formed. In addition, since a vortex is formed on the rear surface of the vertical control panel 6 similar to the above-described embodiment, most of the floating contaminants 5 are introduced into the collecting pipe 3 by the flow, so that the collection efficiency becomes higher.

Further, the present invention can be similarly applied to other conventional combined sewage-exhaust discharge chambers (fountain manholes) shown in Fig. 5B in which the collecting pipe 3 and the discharge pipe 4 are formed on the same wall surface.

As described above, according to the vortex type water level control device for drainage apparatuses of the present invention, vortices are easily introduced into the collecting pipe 3 to generate floating vortices 5 into the public water. There is a big benefit to being able to reduce spills.
