Cast-in-place concrete pile expanding equipment and construction method of cast-in-place concrete pile
The invention provides diameter expanding equipment for a cast-in-place concrete pile, which comprises an outer sleeve component, an inner sleeve component, an outer sleeve component, an inner sleeve component and an outer sleeve component. The soil breaking structure is arranged on the lower end face of the outer sleeve component, a gap allowing concrete to pass through in the axial direction of the outer sleeve component is formed between the soil breaking structure and the outer sleeve component, and the soil breaking structure is of a structure with the wide upper portion and the narrow lower portion. The invention further provides a construction method of the cast-in-place concrete pile adopting the expanding equipment.
本发明提供了一种混凝土灌注桩的扩径设备，包括：外套管部件，内套管部件，适于与所述外套管部件相互套合；其中，还包括：破土结构，设于所述外套管部件的下端面上，与所述外套管部件间存在供混凝土沿所述外套管部件的轴向通过的间隙，其中，所述破土结构为上宽下窄的结构。本发明又提供了一种采用上述扩径设备的混凝土灌注桩的施工方法。
