Design and construction of water-sealing curtain in deep excavations in sand layer adjacent to sea

Based on a project close to sea in Xiamen, the common measures of waterproof curtain are introduced in deep excavation engineering. Under thick sandy layers and underground obstacles, the geological conditions of this project are quite complex, and the interlocking cast-in-situ piles are used. They work well except partial seepage. Experience in the project can be referred for the similar projects.
