[0002] The combined steel sheet pile support structure is a support system for foundation pit engineering. When the soil body generates lateral pressure due to excavation, the steel sheet pile resists the pressure by relying on its bending stiffness and the embedded action of the embedded part, effectively preventing the collapse of the pit wall soil into the foundation pit, and the closely connected structure can also play a water stopping role, reducing the infiltration of underground water into the foundation pit, thereby creating a safe, stable and relatively dry working environment for underground engineering construction, and ensuring the smooth development of various underground structure construction such as basements and underground pipelines.
