The most commonly used in civil engineering construction is foundation pit excavation and support structure. When civil engineering construction is excavating foundation pits, if the soil of the foundation pit wall is unstable and affected by groundwater or it is restricted by the construction site, adjacent buildings or economic costs, slope excavation cannot be used, then support devices are needed to cooperate with the construction.
