Analysis on Key Construction Technology of Reverse Method in Coastal Building
Based on the deep foundation pit engineering constructed by reverse method in Macao's Treasure Island Hotel,this paper expounds the construction technologies of earthwork excavation and key node connection in the reverse construction process of coastal buildings.By optimizing the selection of mechanical equipment and the location of soil sampling in earthwork excavation,the amount of underground excavation has been effectively reduced,and the excavation efficiency has been improved.At the same time,the connection mode and construction technology of underground horizontal structure and vertical structure are explored,which ensures the quality of reverse construction and saves the construction period.The research has achieved good economic and technical benefits,providing reference for the subsequent reverse construction of underground structures in coastal buildings.
