Drainage pumps are mainly used to lower the groundwater level and maintain the water level at a certain level, and are widely used in underground construction projects. During underground mining, drainage pumps can pump water that has penetrated into the mine to the ground to ensure that the mine is dry. In open-pit mining, drainage pumps are used to lower the surface water level until the water in the coal mine is drained to ensure that the bottom of the pit is dry. In addition, drainage pumps are also used in the lowering and drainage pipelines of subways, highway bridges or underground buildings to prevent the collapse of sand and soil on the pit wall and ensure construction safety. 1
Types of drainage pumps include sewage drainage pumps, submersible drainage pumps and submersible pumps. Depending on the different usage scenarios, vertical or dry-mounted drainage pumps can be selected. Some drainage pumps do not require suction and can be driven by explosion-proof motors. In deep foundation pit or tunnel construction, the selection of drainage pumps needs to be technically adjusted according to specific needs to ensure efficient operation.
