Prefabricated combined shear-resistant foundation pile
The invention discloses a prefabricated combined shear-resistant foundation pile. The foundation pile comprises a solid square pile on an upper portion and a hollow pipe pile on a lower portion, wherein a pile adapter is arranged between the solid square pile and the hollow pipe pile; an upper end of the pile adapter is a square in butt joint with an upper square pile, a lower end is a circle in butt joint with a pipe pile, and the middle is of a variable cross-section structure gradually changing from the square to the circle; a square end plate equivalent to the square section in size is arranged at the upper top of the pile adapter, and a circular end plate equivalent to the circular section in size is arranged at a lower bottom of the pile adapter; two ends of the pile adapter are different in shape and size, square piles and pipe piles which are different in shape can be effectively connected, and the pipe piles are converted into the square piles under the condition that the bearing capacity of the upper pile and the bearing capacity of the lower pile are equal. The foundation pile is advantaged in that the section of the pile adapter is gradually changed, the pile adapter can be slowly transited from a square section to a circular section, reinforcing bars are gradually changed, so thickness of a reinforcing bar protective layer of the pile adapter is moderate, the outer layer concrete cannot be crushed due to overlarge thickness, and the reinforcing bars cannot be rusted due to oversmall thickness.
一种预制组合抗剪基础桩，包括上部为实心方桩和下部为空心管桩，在实心方桩和空心管桩之间设有连桩转接头；所述连桩转接头的上端为与上部方桩对接的方形，下端为与管桩对接的圆形，中间为由方形向圆形渐变的变截面结构；桩转接头上项部设置有与方形截面尺寸相当的方形端板，下底部设置有与圆形截面尺寸相当的圆形端板；连桩转接头两端形状尺寸不同，可将形状不同的方桩与管桩有效进行连接，在上下桩承载力相当的情况下，将管桩转为方桩。断面采用渐变的方式，可使桩转接头由方形截面缓缓过渡到圆形截面，配筋渐变的方式，使桩转接头的钢筋保护层厚度适中，不会因为厚度过大而导致外层混凝土被压碎，也不会因为过小而致使钢筋发生锈蚀。
