the method comprises the following steps: arranging a sewage pumping and discharging device at a position needing water discharging in the tunnel, installing an inner shielding assembly, and determining whether to install a discharging device according to the collection condition of sewage in the tunnel and the use purpose of pumped and discharged clear liquid; when the drainage device is installed, the precipitation corrugated pipe connected with the drainage end of the precipitation water pump extends to the inner cavity of the drainage bin, drainage is carried out through the drainage pipe connected with the drainage hole, and when the drainage device is not installed, an extension pipe is additionally connected to the pipe orifice of the precipitation corrugated pipe connected with the drainage end of the precipitation water pump for drainage;
step two: according to the height of the water level of the sewage collected in the tunnel, a screw rod motor is started, and the limiting extraction bin is adjusted to move downwards to a water flow positioning extraction point in the tunnel;
step three: starting a water taking pump to pump water to a treatment bin, and carrying out precipitation treatment on the sewage in the treatment bin for a certain time;
step four: the settling water pump pumps and discharges the settled clear liquid to a designated position, a sludge discharge port of the treatment bin slides out of an outlet of the settling bin, the driving mechanism drives the sludge scraping plate to move towards the sludge discharge port, the inner wall of the treatment bin is scraped and brushed, the bin door is opened, and the dirt is discharged from the sludge discharge port;
step five: the driving mechanism and the mud scraper reset, the bin door is closed and locked, and the treatment bin resets; waiting for entering the next round of pumping and draining work.
According to the invention, the extraction limiting bin is arranged in the water flow through the screw rod motor, the extraction water pump is started, the extraction corrugated pipe at the water extraction end is limited by the position of the extraction limiting bin to extract the water flow, and when the height of the water level changes, the height of the extraction limiting bin is adjusted through the screw rod motor again, namely, the extraction limiting bin can stretch the extraction corrugated pipe, so that the extraction at a lower water level can be facilitated. Carry out the sediment of certain time through handling the storehouse earlier to inside rivers, filth such as silt of aquatic can deposit in the bottom of handling the storehouse, and upper clear liquid extracts the discharge through precipitating the water pump, and actuating mechanism drive mud scraper scrapes the processing to the internal surface of handling the storehouse to scrape the discharge with the sediment to mud discharge mouth one end, handle the automatic clear-up in storehouse, made things convenient for the sediment of next round to use. When carrying out sewage pump drainage, earlier hide the subassembly through interior and carry out the pump drainage to handling the storehouse after the multilayer filtration to rivers in the tunnel, discharge behind the rethread sedimentation treatment to the discharged clear solution can be retrieved and is used for other uses, reaches the reutilization of water resource. Through processing storehouse sliding connection in deposiing the storehouse, the storehouse export is deposited in the roll-off of one end, and the sealed self-locking mechanism of door realizes the automatic locking and the unblock of door and bulkhead, promotes the door and opens after the wiper scrapes the brush, has saved the manual work, very big the automated processing who has made things convenient for deposit in the processing storehouse. Through the discharge device arrangement of detachable connection, the stirring effect of the stirring assembly in the discharge bin can accelerate the dissolution of some added substances with specific purposes, and the discharged water resources are utilized secondarily in a targeted manner (for example, a cleaning agent is added in the discharge bin, and the stirring assembly is used for cleaning the ground after stirring, etc.).
The present invention is not limited to the above-described embodiments, and various modifications made without inventive step from the above-described concept will fall within the scope of the present invention for those skilled in the art.
