Technical Field
[0001] This utility model relates to a support structure, specifically a reinforced concrete support structure for deep foundation pits in soft soil. Background Technology
[0002] An excavation pit is a pit dug at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the situation of nearby buildings, and waterproofing and drainage work should be carried out. For shallow excavations, slope protection can be used to stabilize the soil slope, and the slope should be determined according to relevant construction regulations. For deeper excavations or those near buildings, excavation pit wall support methods, shotcrete wall protection methods, and even methods such as underground continuous walls and interlocking column-type bored piles can be used for large excavation pits. Most existing support structures are large plate-shaped protective plates, which need to be spliced and installed by workers during support, and are not easy to adjust for different angles of the excavation pit slope, which has certain limitations. Therefore, a reinforced concrete support structure for deep soft soil excavation pits needs to be designed to solve this problem. Utility Model Content
