る。2. Description of the Related Art Conventionally, this type of pumping station is provided with an inflow channel 4 opened and closed by an inflow gate 3 between a pipe 1 and an inflow channel 2 as shown in FIGS. Sewage flowing down from the sewer 1 to the inflow culvert 4 with the gate 3 opened is introduced into the water absorption tank 6 from the inflow waterway 2 through the forwardly inclined surface 5, and the pump installed in the water absorption tank 6. It is configured to suck up by P1 and P2.

る。However, in the above-mentioned conventional sewage relay pumping station, when there is no sedimentation basin, a part of the scum, scum, and sediment flowing down into the inflow channel 2 together with the sewage settles on the bottom surface 2A of the inflow channel 2. These accumulate on the bottom surface 2A over time.

えられる。Therefore, for example, after the inflow gate 3 is closed and water is stored in the inflow channel 4, the inflow gate 3 is opened to flush the water in the inflow channel 4 into the inflow channel 2 by flushing. It is conceivable that most of the scum, scum, and sediment deposited in the water channel 2 are flushed to the water absorption tank 6.

In a pumping station configured so that water flowing down from a culvert to an inflow culvert flows down the forwardly inclined surface from the inflow channel, is introduced into a water absorption tank, and is sucked up by a pump installed in the water absorption tank. A screen guide screen extending from the upstream end of the downwardly inclined surface to near the installation position of the pump is provided so as to face the downwardly inclined surface.

され、ポンプによって吸い上げられる。According to the present invention, in the normal state in which the inflow gate is opened, the flow rate of the sewage flowing down the inflow channel is low, so that the sewage is filtered by the mesh-made induction screen and falls on the forwardly inclined surface. Then, the water flows down the inclined front surface and is introduced into the water absorption tank, and is sucked up by the pump installed in the water absorption tank. In the case of scum, residue, sedimentation, etc., which are mixed into the sewage and flow down from the inflow channel to the net guide screen, those smaller than the mesh of the net guide screen fall together with the sewage on the downward slope. Then, the water flows down the front inclined surface together with the waste water and is introduced into the water absorption tank, and is sucked up together with the waste water by the pump installed in the water absorption tank. On the other hand, among the scum, scum, sediment, and the like that have been mixed into the sewage and flowed down from the inflow channel to the mesh induction screen, those larger than the mesh of the mesh induction screen are collected by the mesh induction screen and collected. Remains on a net-guided screen. On the other hand,
If some of the scum, sediment, and sediment that flowed down into the inflow channel together with the sewage settled on the bottom of the inflow channel and accumulated on the bottom over time, for example, the inflow gate was closed and the After storing the water, the inflow gate is opened.
Thereby, the water of the inflow channel is rapidly discharged into the inflow channel. In the inflow channel, the sewage flows down at a high speed, and most of the scum, scum, and sediment deposited in the inflow channel are flushed toward the induction screen made of mesh. Most of the high-speed sewage flow that arrives at the net guide screen slides on the net guide screen with scum, scum, etc., and the net guide screen is inclined upward and forward. It gains the flight distance from the front end of the net-made guide screen and falls near the pump in the water absorption tank. In addition, a part of the high-speed sewage flow that has reached the mesh-made induction screen falls on the downwardly inclined surface, flows down the downwardly inclined surface, is introduced into the water absorption tank, and is sucked up by the pump.

９，９内で沈砂が堆積するのを防止することができる。If a part of the scum, scum, and sediment flowing down into the inflow channel 2 together with the sewage settles on the bottom surface 2A of the inflow channel 2 and accumulates on the bottom surface 2A over time,
At this timing, the inflow gate 3 is closed and the water is stored in the inflow culvert 4 (for example, at night in fine weather). When the water level of the inflow channel 4 rises to a predetermined level WL, the inflow gate 3 is opened. As a result, the water stored in the inflow channel 4 is rapidly discharged into the inflow channel 2, and the sewage flows down at high speed in the inflow channel 2, and scum, scum, sediment, and the like deposited on the bottom surface 2 </ b> A are formed by a net-shaped induction screen. Push away towards 11. Most of the high-speed sewage flow that has reached the mesh-made induction screen 11 is
The scum, residue, earth and sand, etc., are slid on the net-shaped guide screen 11, and the net-made guide screen 11 is inclined upward and forward from the front end of the net-made guide screen 11. Earn the flight distance and fall into the pre-swirling tanks 9,9. In addition, a part of the high-speed sewage flow that has reached the net-made induction screen 11 falls onto the front-sloping inclined surface 5, flows down the front-sloping inclined surface 5, and flows from the inflow passages 10, 10 into the pre-swirl tank. 9 and 9 are introduced. Sewage introduced into the pre-swirling tanks 9, 9 and scum, residue, sedimentation, etc. larger than the mesh of the net-shaped guide screen 11 are pre-swirled in the same direction R2 as the rotation direction R1 of the impellers of the pumps P1 and P2. Pump P
1 and P2 are collected immediately below the inlet 12. Therefore, these are uniformly and efficiently sucked from the entire circumference of the suction port 12. In addition, the pre-swirling flow generates a "sweeping action" for scavenging the sediment, and the sediment is sucked from the suction ports 12 of the pumps P1 and P2 without depositing the sediment, and the sand is deposited in the pre-swirling tanks 9, 9. Can be prevented.

る。As described above, according to the present invention, in the normal state where the inflow gate is opened, the scum, sewage, sediment, etc., which are mixed into the sewage and flow down from the inflow channel to the induction screen made of mesh, The screen smaller than the mesh of the mesh-made induction screen is dropped together with the sewage on the downwardly inclined surface, and the downwardly inclined surface is flowed down together with the sewage and introduced into the water absorption tank. The pump installed in the water absorption tank Scum, residue, sediment, etc. that can be sucked up together with the sewage and mixed into the sewage and flow down from the inflow channel to the mesh induction screen, those larger than the mesh of the mesh induction screen are mesh induction screens. Scum, scum, and part of the sediment that have flowed down into the inflow channel together with the sewage are collected on the bottom surface of the inflow channel. If these fall down and accumulate on the bottom over time, for example, the inflow gate is closed and water is stored in the inflow channel, then the inflow gate is opened, and the water in the inflow channel is rapidly discharged into the inflow channel, The high-speed sewage flow that arrives at the net guide screen slides on the net guide screen, and the net guide screen is inclined forward to increase the flight distance and increase the pump distance in the water absorption tank. Since it can be dropped nearby, if a flash is generated that suddenly discharges water into the inflow channel, scum, residue, sediment, etc. will remain on the downward slope and accumulate over time. These can be sucked up by a pump and discharged to the outside of the pumping station together with sewage.
