Research on Construction Technology for Excavation Support Structures in Water Conveyance Tunnels
In response to prominent issues such as the significant depth of foundation pits,limited site space,high permeability,weak ground layers,and the inadequacy of traditional construction techniques,focusing on tunnels in the Pearl River Delta,by analyzing and evaluating the geological conditions,this paper optimizes the construction technology for underwater jet grouting piles and proposes a technical solution that combines various construction methods such as underground diaphragm walls and trenching.The results demonstrate that this technology is highly effective for deep foundation pit construction in complex site conditions.
