Technical Field
[0001] This utility model relates to the field of building protection equipment technology, specifically a shielding and protection device for elevated bridge construction. Background Technology
[0002] An elevated bridge is a bridge that crosses deep ravines and canyons instead of high embankments, as well as a bridge that crosses roads in urban areas. It is supported by high-supported towers or pillars. During the construction of an elevated bridge, protective shielding devices are required for construction protection.
[0003] Application number CN202221934026.X discloses a protective device for elevated bridge construction, including a protective enclosure. The right side of the protective enclosure has a combination groove, and the left side is fixedly connected to a combination block… This facilitates assembly by workers, improving their work efficiency.
