Background
The CFG pile (cement fly-ash Gravel) is a high-bonding-strength pile formed by mixing cement, fly ash, broken stone, stone chips or sand with water, and the pile, the soil among the piles and a mattress layer form a composite foundation together. The CFG pile composite foundation has the characteristics of large bearing capacity improvement range, small foundation deformation and the like, has a large application range, and is widely applied to foundation treatment of projects such as railways, highways, ports, buildings and the like.
In the CFG pile composite foundation, the pile body not only bears the vertical load distributed to the pile top by the cushion layer, but also bears the lateral thrust caused by the shearing deformation of the soil between the piles under the action of the vertical load, and the shearing resistance of the upper part of the pile body has important influence on the overall stability of the composite foundation.
The rear-inserted steel reinforcement cage CFG pile is a pile type appearing in recent years, and the steel reinforcement cage is inserted into a common CFG pile, so that the shearing resistance of a pile body is improved, the shallow pile body is prevented from being damaged due to local horizontal thrust, and the probability of defects such as diameter shrinkage, diameter expansion, pile breakage and the like in the construction process is reduced.
Because the steel reinforcement cage in the post-inserted steel reinforcement cage CFG pile is inserted after the pile body mixture is filled, the resistance is very large when the steel reinforcement cage is inserted; on the other hand, the CFG pile is usually longer and smaller in diameter (for example, in a vibration pipe sinking pile forming process, the diameter of the pile is generally 350-600 mm), the number of main reinforcements of the reinforcement cage is small, the overall rigidity of the reinforcement cage is small, and bending deformation or damage is easy to occur. Therefore, when the reinforcement cage is inserted, auxiliary sinking measures must be taken frequently.
