Composite anti-sliding pile and construction method
The invention discloses a composite anti-sliding pile and a construction method. The composite anti-sliding pile comprises an anti-sliding pile body and a reinforced body, the anti-sliding pile body is used for being arranged in a pile well, the pile well penetrates through a bard soil layer, a soft interlayer and a bottom hard soil layer, the anti-sliding pile body is of a rectangular structure,one end of the reinforced body penetrates through the pile well and is embedded into the soft interlayer and the bottom hard soil layer, and the other end of the reinforced body is fixedly connected with the anti-sliding pile body. The reinforced body is arranged outside the pile body where the anti-sliding pile body penetrates through the soft interlayer, the cross-section size of the anti-sliding pile in the soft interlayer is increased locally, the anti-sliding pile of the rectangular structure has good bending and shear strength, thus multiple anti-sliding piles do not need to be arrangedto enhance the bearing capacity in the difficult stratum, the length of the anti-sliding pile is reduced, other types of piles also do not need to be arranged to reduced the length of single pile, theproblem that the anti-sliding pile in the difficult stratum cannot reach the design pile length is solved, the support stability and safety of the anti-sliding pile in the difficult stratum are ensured, and the project investment is saved.
本发明公开了一种复合型抗滑桩和施工方法，包括抗滑桩桩身和加筋体，抗滑桩桩身用于设于桩井中，桩井穿过硬质土层、软弱夹层和底部硬质土层，抗滑桩桩身为矩形结构，加筋体的一端穿过桩井埋设在软弱夹层和底部硬质土层中，加筋体的另一端与抗滑桩桩身固定连接。抗滑桩桩身穿过软弱夹层的桩体外设置有加筋体，局部增大了抗滑桩桩身在软弱夹层中的截面尺寸，矩形结构的抗滑桩具有良好的抗弯和抗剪强度，使该抗滑桩在困难地层中不需要设置多根抗滑桩来增强承载能力，减小了抗滑桩的长度，也不需要设置其他类型的桩来减小单根桩的长度，解决了困难地层抗滑桩无法达到设计桩长的问题，确保抗滑桩在困难地层中的支护稳定性和安全性，节约工程投资。
