Research on Key Techniques of Diagonal Pile Embedded in Sea Bedrock Exposed to Air
Diagonal rock-embedded pile is the technique of rock-embedded cast-in-situ piles with a certain slope applying to the geological condition of shallow bedrock or without cover layer.Steel pipe pile is used as steel casing of rock-embedded cast-in-situ pile,the depth of the steel casing driven into soil cannot transformed into stable pile foundation due to seabed terrain.By analyzing the status of steel casing with a certain slope under the action of gravity itself,the gravity of water inside the steel casing,wave force,water current force,soil pressure,etc.,and calculating the minimum depth of the pile driven into soil under the most unfavourable working condition,an artificial foundation bed is formed,which can ensure pile stability.The research is a solution to technical difficulties in the construction of diagonal pile embedded into the sea bedrock exposed to air or the foundation with thinner cover layer,also provide a theoretical basis for the construction of diagonal piles embedded in rock.
