Description

Technical Field

[0001] The utility model relates to a water channel protection device, in particular to the structure of the water channel protection device. Background Art

[0002] Salt lake brine is rich in minerals such as sodium chloride, potassium chloride and magnesium chloride, and is the main raw material for the production of potassium, magnesium and lithium. There are two ways to mine brine: canal mining and well mining. Among them, canal mining is to mine shallow brine through the brine mining canal, and pump the brine in the brine mining canal into the salt pan for evaporation and crystallization. When the crystal thickness reaches the required level, it is used. When extracting brine from the brine mining canal or draining brine between salt pans, the brine is pumped out through the brine pumping station and transported to the corresponding location through the brine transport canal.

[0003] The dams and brine channels used to construct salt fields are usually built with local soil. Since the brine has a certain water pressure when it is discharged from the outlet of the brine pumping station after being pressurized by the brine pumping station, and the brine pumping station is relatively high, while the brine channel is relatively low, the brine impact will cause damage to the salt field dam or the slope of the brine channel, causing the dam foundation below the outlet of the brine pumping station to collapse, and there is a risk of dam breach in severe cases. In addition, a large amount of soil impacted by the brine will mix into the brine, which will cause the quality of the carnallite to deteriorate.

[0004] In order to reduce the damage caused by the water discharged from the outlet of the brine pumping station to the salt field embankment or the slope of the brine delivery channel, the existing method usually sets a water channel on the slope of the salt field embankment or the brine delivery channel below the outlet of the brine pumping station, and lays an HDPE anti-seepage membrane in the water channel. However, due to the large water output and high drop of the brine pumping station, the water flow directly impacts the HDPE anti-seepage membrane, and the HDPE anti-seepage membrane is often damaged, requiring frequent shutdowns for repairs, which not only causes safety hazards but also affects normal production.

[0005] The utility model aims to solve the problem that when the existing brine pumping station pumps brine, the water flow easily damages the salt field embankment and the slope of the brine delivery channel, causing safety hazards and affecting normal production. Utility Model Content
