Research on the Key Technology of Municipal Pipe Gallery Foundation Pit Support System and Earthwork Excavation
Based on Longlan Avenue north extension en-gineering in Longhua District of Shenzhen City,this paper conducts optimization design of foundation pit retaining structure from the perspectives of technical standards and safety level classification of comprehensive pipe gallery foundation pit engineering.Combined with the character-istics of surrounding environment of the engineering,the foundation pit dewatering measures of water collection and open drainage are put forward,and the key node technolo-gy in earthwork construction of deep and large foundation pit is emphatically analyzed.The research results can pro-vide some guidance for similar engineering.
