复杂交互地层高频振动沉拔长护筒桩基技术研究

Research on The Technology of High-frequency Vibration Sinking and Pulling Long Protective Cylinder Pile Foundation in Complex Interactive Formations

在土木工程中,桩基结构是十分重要的部分,现有常用的三种桩基分别是锤击沉桩法、静压沉桩法和振动沉桩法,此三种方法都有一定局限性。文中结合工程实际情况,拟对振动沉桩法做出改进,通过采用钢护筒配合振动,以达到提高施工效率的目的。

In the construction of civil engineering, the pile foundation structure is a very important part, and the three types of pile foundations that are widely used are hammered pile method, static pressure pile method and vibrating pile method, which have certain limitations. In this paper, combined with the actual situation of the project, it is proposed to improve the vibration pile method, and use the steel guard cylinder with vibration to achieve the purpose of improving the construction efficiency.
