Description

Technical Field

[0001] The utility model relates to the field of deep foundation pit engineering, in particular to a protective device for steel lattice columns. Background Art

[0002] At present, deep foundation pit support mainly adopts pile support system. In the pile support system, the internal support needs to use steel lattice columns to transfer vertical loads. Before the construction of the internal support, a section of steel structure column is inserted into the steel lattice column using bored piles, and the top is then anchored into the internal support. The entire section is buried in the soil. During the earth excavation process, due to operator negligence or insufficient light on site, construction machinery may collide with steel lattice columns, causing deformation of steel lattice columns and cracking of internal supports, which in turn causes safety accidents such as instability of internal supports and supporting piles. Therefore, how to effectively strengthen the protection and warning of steel lattice columns during earth excavation, so that construction machinery and lattice columns maintain a certain safe distance to avoid the occurrence of safety accidents is a technical problem that needs to be solved urgently.
