Pile foundation equipment applied to complex foundation and pile forming construction method
The invention discloses pile foundation equipment applied to a complex foundation and a pile forming construction method, belongs to the technical field of rotary excavating pile construction, and aims to solve the technical problem that in the prior art, a valve pile shoe cannot normally sink as when acting on a soft soil layer under the vibration force of an upper hammer. The device comprises a lifting rack, an inner barrel, a twist drill and an outer barrel, the outer cylinder is movably connected with the lifting rack through an outer cylinder lifting mechanism; the twist drill is movably connected with the lifting rack through a twist drill lifting mechanism; the inner cylinder is connected with the twist drill lifting mechanism through an inner cylinder hydraulic separation mechanism; and the inner cylinder, the twist drill and the outer cylinder are concentrically arranged. According to the pile foundation equipment applied to the complex foundation and the pile forming construction method, operation is easy, construction is convenient and fast, and construction pile forming of the complex stratum can be achieved while the construction efficiency of the original working condition can be improved.
本发明公开了一种应用于复杂地基中的桩基设备及成桩施工方法，属于旋挖桩施工技术领域，以解决现有技术中活瓣桩靴在上部锤头的振动力下无法像作用于软土层时一样正常下沉的的技术问题。它包括升降机架、内筒、螺旋钻和外筒；所述外筒通过外筒升降机构与所述升降机架活动连接；所述螺旋钻通过螺旋钻升降机构与所述升降机架活动连接；所述内筒通过内筒液压分离机构与所述螺旋钻升降机构连接；所述内筒、螺旋钻和外筒同心设置。本发明应用于复杂地基中的桩基设备及成桩施工方法，操作简单、施工便捷，能够提升原有工况施工效率的同时实现复杂地层的施工成桩。
