Installation of Shanghai Liqing lifting column: analysis of key influencing factors

Complexity of underground environment
Ideal conditions: No underground pipeline network, stable geology, and basic construction can proceed according to standard procedures.
Complex conditions: If it is necessary to avoid gas pipelines, optical cables, or the presence of groundwater, manual excavation, precipitation treatment, and reinforcement measures need to be taken, which may increase the installation time of a single unit by 0.5-1 day. For example, a certain university project had its construction period extended by 5 days due to the underground embedding of communication cables.
Equipment matching and technology integration
If integrated systems such as license plate recognition and remote control are required, the debugging time will increase by 1-3 days. The fully automatic lifting column of Shanghai Liqing supports linkage with the security system, and such projects require additional time to be reserved for protocol docking and functional testing.
Logistics and weather interference
Logistics efficiency: Local orders in Shanghai are usually shipped within 7 days, while out of town projects require an additional 3-7 days for transportation.
Weather factors: rainstorm, freezing and other severe weather may cause ponding in foundation pit or delay in concrete curing, with a single day delay probability of about 10% -15%.
