The present invention relates to a flux measurement device for a sewer pipe. Wastewater flows through a sewer pipe by filling the sewer pipe or without filling the sewer pipe. More particularly, a flux measurement device for a sewer pipe is developed for measuring accurate flux by solving a problem that the measurement of flux was difficult since the flux can be varied according to the state of a sewer pipe. The present invention includes: a manhole for opening an internal space through a manhole lid formed on the ground surface; an inlet sewer pipe for having a drain valve for accepting wastewater through the manhole and discharging deposits downward by forming the lower part vertically penetrated; an outlet sewer pipe for discharging the wastewater in the manhole in a location lower than the inlet sewer pipe; a flux measurement pipe having a diameter (D2) greater than a diameter (D1) of the inlet sewer pipe and being equipped with a flowmeter; a first connection pipe for connecting the inlet sewer pipe and the flow measurement pipe, having a piezometer capable of measuring water pressure in the upper part and being equipped with a thrust gate valve, wherein the thrust gate valve is installed between the inlet sewer pipe and the connection pipe and makes wastewater in the inlet sewer pipe directly flow into the manhole by being connected to the inlet sewer pipe when the connection pipe descends and separating a part connected with the inlet sewer pipe from the inlet sewer pipe when the inlet sewer pipe ascends; a second connection pipe installed in one side of the flux measurement pipe which is not connected with the first connection pipe; an elbow pipe upwardly curved by making one side be connected to the second connection pipe and having an opened lower part of the other side thereof formed at the same as or to be higher than a height of an upper end of the flux measurement pipe; and a winding device for ascending and descending a lift bar of which lower part is fixed to the connection pipe and the upper part is penetrated and extended to the ground. |
