[0002] For modern urban buildings, high-rise buildings are the main component of urban buildings, and the height of buildings is constantly being refreshed. If the geological conditions of the base are good, raft foundations are generally used. In order to meet the force requirements of the foundation, the thickness of the raft of high-rise buildings is generally thicker. For foundations with ultra-thick rafts, the surface reinforcement support methods include steel pipe support and steel bar support. When steel pipe support is used, the hollow inside the steel pipe needs to be filled with grouting, which is not conducive to the construction period and is not economical. When steel bar support is used, especially for ultra-thick rafts with a thickness of ≥3m, the strength and rigidity of the steel bar support are insufficient, which is not conducive to the stability of the support system and is prone to overturning and collapse safety problems. How to ensure the stability and safety of the support system is a major problem that must be solved during the construction process. Utility Model Content
