Guide hole and pile sinking integrated prefabricated pipe pile construction method
The invention relates to the technical field of foundation treatment equipment, in particular to a guide hole and pile sinking integrated prefabricated pipe pile construction method which is used for carrying out pile sinking construction on a prefabricated pipe pile. A movable pile tip capable of rotating at the same time is arranged in the prefabricated pipe pile, the pile tip and the prefabricated pipe pile are of a split structure, the pile tip is driven to move and rotate to stir a soil layer at the pile end of the prefabricated pipe pile in the pile sinking process, and the soil layer in the pile sinking range of the prefabricated pipe pile is locally loose and soft; and after the soil layer is locally loose and soft, pile sinking construction of the prefabricated pipe pile continues to be conducted till the designed depth is reached. The method has the advantages that the method is suitable for engineering construction in the pile sinking process of the prefabricated pipe pile, in the pile sinking process, when a hard soil layer with a large local area is encountered, loosening treatment on the hard soil layer can be rapidly achieved, the sinking resistance of the hard soil layer to the prefabricated pipe pile is rapidly reduced, and the pipe sinking efficiency is greatly improved.
本发明涉及地基处理设备技术领域，尤其是一种引孔与沉桩一体化预制管桩施工方法，对所述预制管桩进行沉桩施工；在所述预制管桩之内设置可移动并可同时旋转的桩尖，所述桩尖与所述预制管桩为分体式结构，驱动所述桩尖移动及旋转对所述预制管桩在沉桩过程中的桩端土层进行搅动，使所述预制管桩的沉桩范围内的土层局部松软；当土层局部松软后，继续进行所述预制管桩的沉桩施工直至其设计深度。本发明的优点是：适用于预制管桩沉桩过程工程施工，在沉桩过程中，遇到局部活较大面积硬质土层时，能够快速实现对硬质土层的松动处理，快速降低硬质土层对预制管桩的下沉阻力，大幅提高沉管效率。
