Deep Excavation Shoring
Project Overview
The Roméo Golf Project involves the construction of a deep excavation shoring system designed to support excavation works reaching a depth of 13 meters. The retaining structure consists of spaced bored piles with a diameter of 60 cm, installed at regular intervals to form the primary support wall. To provide sufficient lateral resistance and maintain stability throughout the excavation phases, the system is reinforced with three rows of prestressed soil anchors.
The subsurface conditions at the site include loose to medium dense pure sand, underlain by a cemented sand layer. These soil formations present contrasting strength characteristics, requiring careful attention during the design and installation of the shoring components. Due to the presence of a high groundwater table, a dewatering system was implemented to lower the water level below the final excavation depth, ensuring dry and safe working conditions throughout construction.
The adopted shoring and dewatering system balances soil behavior, water pressure, and structural requirements, creating a controlled environment for the continuation of excavation works.
