Description

Technical Field

[0001] The utility model relates to the technical field of subway tunnels, in particular to a subway tunnel construction drainage device. Background Art

[0002] Subway tunnel refers to an underground passage used for subway operation. It is usually built of concrete or reinforced concrete structure to carry subway tracks and ensure the safe operation of trains. The tunnel is equipped with drainage systems, cable channels, emergency evacuation exits and other facilities. The construction of the tunnel needs to fully consider factors such as geological conditions, groundwater levels and surrounding environment.

[0003] Subway tunnels are generally built underground in cities. Compared with underground in the wild, there will be more garbage underground in cities. When drainage is needed during subway tunnel construction, the groundwater contains not only mud and sand, but also bags, ropes and other unoxidized garbage. Because the ropes are relatively thin and long, sometimes a simple filter basket cannot filter them out. The ropes enter the water pump, which can easily cause damage to the water pump and affect the progress of construction. Utility Model Content
