Technical Field
[0001] This utility model relates to the field of foundation pit internal support technology, specifically to the construction structure for foundation pit support replacement and internal support removal. Background Technology
[0002] Internal support for foundation pits refers to a technical means of maintaining the stability and safety of foundation pits during excavation by installing support structures inside the pit to balance lateral pressure and prevent collapse. Internal support structures typically consist of steel supports, concrete supports, or a hybrid of steel and concrete. Their function is to transfer and balance the water and soil pressure acting on the retaining structure, and together with the retaining structure, they form a support system.
[0003] Currently, when replacing or removing the internal support structure in a foundation pit, cranes and other lifting equipment are typically used to move the internal support structure out of the pit. However, the use of existing cranes and other lifting equipment for fixing the internal support structure requires a high degree of personnel involvement, which increases the labor intensity to some extent. Therefore, this invention proposes a construction structure for foundation pit support replacement and internal support removal. Utility Model Content
