Advantages and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings.

Figure 2 is an operating state diagram of the state of pumping sewage and ITO in the sewage manhole in the schematic diagram of the soil removal system according to the present invention. The Ito exclusion system comprises a sewage pumping station 21, a sewage manhole 23, a sewage pressure feed pipe 25, an Ito exclusion pipe 27, and a gate valve 29.

The sewage pumping station 21 has a sewage pump 31 and is configured to pump the sewage collected in the sewage pumping station 21 through the inlet pipe 33 provided on one side thereof to the sewage pumping pipe 25. . The sewage pump 31 is configured to be activated or stopped depending on the level of the introduced sewage. To this end, the sewage pumping station 21 is preferably provided with upper and lower limit switches 35 and 37 for detecting the level of sewage. That is, the sewage pump 31 is started by the detection of the sewage by the upper and lower limit switches 35 and 37, and the sewage pump 31 is stopped by the detection of the sewage by the lower limit switch 37.

When the Ito exclusion system is installed across the river 39, the sewage pumping station 31 is provided on one side of the river 39, and the bottom of the river 39 is based on the bottom thereof. It is desirable to be installed at a lower position.

The other side of the stream 39 provided with the sewage pumping station 21 is provided with the sewage manhole 23. The sewage manhole 23 is configured to supply sewage pumped from the sewage pumping station 21 to a sewage treatment plant (not shown). The sewage manhole 23 is preferably installed at a position substantially higher than the sewage pumping station 21 and the lower bed 41 of the river 39 on the basis of its bottom so as to naturally supply the pumped sewage to the sewage treatment plant. Do.

The sewage pumping pipe 25 interconnects the sewage pumping station 21 and the sewage manhole 23 to enable the pumping of sewage. The sewage pressure feeding pipe 25 is buried in the ground of the lower bed 41 so as to cross the stream 29.

The sewage pumping pipe 25 supplies the sewage from the sewage pumping station 21 to the sewage manhole 23 during the operation of the sewage pump 31, and the sewage level of the sewage pumping station 21 is increased by the supply of such sewage. When the operation of the sewage pump 31 is lowered to lower, the charged state of the stopped sewage is maintained.

When the operation of the sewage pump 31 is stopped in this way, the sewage flowing through the sewage pressure feed pipe 25 is stagnated in the pipe. Thus, it is necessary to return the sewage stagnant in the sewage pumping pipe 25 to the sewage pumping station 21, and to prevent it from accumulating in the sewage pumping pipe 25 of the soil contained in this sewage.

The Ito exclusion pipe 27 is connected to the bottom of the sewage pump 25 and the bottom of the sewage pumping station 21 located lower than this bottom. That is, the sewage pressure pipe 25 supplies sewage from the sewage pumping station 21 to the sewage manhole 23, and this ITO exclusion pipe 27 includes sewage in the sewage water pressure pipe 25 when the sewage pressure pumping stops. Return to the sewage pumping station 21 to be able to re-feed.

The gate valve 29 is provided so as to selectively carry out such pumping of wastewater or return of wastewater and soil. It is preferable that this gate valve 29 is formed in the opening-closing structure, and is provided in the sewage pumping station 21 side of the earth exclusion pipe 27.

That is, this gate valve 29 is closed as shown in FIG. 2, and does not prevent the sewage of sewage in the arrow direction a, and as shown in FIG. Only open at the time allows the return of sewage and soil in the direction of the arrow b.

The Ito exclusion pipe 27 and the gate valve 29 prevent the ITO from being loaded into the sewage pressure feed pipe 25, so that the separate structure of the Ito valve chamber is unnecessary as in the prior art, and the river by the Ito valve chamber Eliminates the possibility of contamination and facilitates maintenance.

The sewage pump 31, the gate valve 29, and the upper and lower limit switches 35 and 37 are preferably configured to be interlocked and controlled automatically by a separate control device.

The ITO exclusion system configured as described above is controlled as in the flowchart of FIG. 4.

That is, wastewater is always introduced into the sewage pumping station 21 through the inflow pipe 33 (ST10).

Subsequently, the sensing step ST20 proceeds. The sensing step ST20 detects the level of the sewage introduced by the upper and lower limit switches 35 and 37 as described above.

Subsequently, the determination step ST30 proceeds. This determination step ST30 determines whether the sewage level detected in the detection step ST20 is any one of the lower limit (ST31), the lower limit and the upper limit (ST32), and the upper limit or more (ST33).

If the sewage level is between the lower limit and the upper limit (ST32) and above the upper limit (ST33) in the determination step (ST30), the sewage pump operation step (ST41) for closing the gate valve 29 and operating the sewage pump 31 proceeds. do.

The sewage that has flowed into the sewage pumping station 21 and the soil contained in the sewage by this sewage pump operation step ST41 are pumped to the sewage manhole 23 through the sewage pressure pipe 25 (ST51).

When the sewage level is lower than the lower limit (ST31) in the determination step ST30 due to the pumping of the sewage, the gate valve opening step ST42 for stopping the operation of the sewage pump 31 and opening the gate valve 29 is performed. .

Subsequently, the Ito return step ST52 proceeds. In this Ito return step ST52, the filthy water and Ito remaining in the filthy water pump pipe 25 are naturally returned to the effluent pumping station 21 by the gate valve opening step ST42.

That is, the Ito exclusion system of the present invention operates the sewage pump 31 according to the sewage pump station 21 of the sewage pumping station 21 to supply the sewage to the sewage manhole 23 through the sewage pressure feed pipe 25, or the sewage pump 31. ) And the gate valve 29 is opened to return the sewage and the ITO remaining in the sewage pump 25 through the Ito drain pipe 27 to the sewage pumping station 21.

Therefore, the soil in the sewage pumping pipe 25 is supplied to the manhole 23 or fed back to the sewage pumping station 21 together with the sewage being fed or returned, so as not to be in a stagnation situation.

Thus, the present invention connects the bottom of the sewage pumping pipe and the bottom of the sewage pumping station with an ITO exclusion pipe and has a gate valve in the ITO exclusion pipe, so that the sewage is pumped or pumped according to the level of the sewage introduced into the sewage pumping station. Io valve chamber, returning to the sewage pumping station and back to the sewage manhole through the sewage pump pipe, so that the separate removal of the ITO contained in the sewage as in the prior art having an Ito valve chamber is unnecessary, It can reduce the construction cost, facilitate the maintenance, and protect the river environment.
