8. The underground roadway reservoir of claim 1 wherein,
the water inlet pipe is also connected with a flushing pipe for flushing the water outlet cylinder;
the front end of the flushing pipe is connected with the water inlet pipe, and the rear end of the flushing pipe faces the water outlet cylinder;
a water flushing pipe control valve is arranged in the water flushing pipe, and a water inlet pipe control valve is arranged in the water inlet pipe;
the front end of the flushing pipe is positioned at the front side of the water inlet pipe control valve.
9. A method of constructing an underground roadway reservoir as claimed in any one of claims 1 to 8, comprising the steps of:
s01: selecting a coal mine abandoned roadway as a construction site, wherein a bottom plate of the roadway has a certain angle, and the top surface of the bottom plate gradually inclines downwards along the direction from back to front;
s02: a water storage area, a primary filtering area, a slow flow area, a secondary filtering area and a water outlet area are sequentially divided from back to front in the roadway, a dredging gate is arranged at the front end, close to the water storage area, of the roadway side, and a sealing door plate is arranged in the dredging gate;
s03: a water inlet pipe is fixed on a top plate of the roadway in advance, and a water outlet cylinder is arranged on the water outlet end of the water inlet pipe;
s04: the gravel water purifying wall is built in the primary filtering area, the water retaining wall is built in the slow flow area, the active carbon water purifying wall is built in the secondary filtering area, and the baffle door is arranged at the front end of the water outlet area;
s05: and the water outlet pipe penetrates through the mounting hole of the shutter and is sealed, so that the construction of the underground roadway reservoir is completed.
