The invention relates to the technical field of foundation piles, and particularly relates to a combined foundation pile composed of a steel pipe pile and a cement soil pile. The combined foundation pile comprises a pile body, a rabbet dowel and a pile cap. Due to the fact that the parameter of the rigidity of soil between piles needs to be considered during pile foundation construction, the numerical difference between the rigidity of the soil between the piles and the rigidity of the pile body is reduced as much as possible, and the soil arching effect is weakened; and when the steel pipe pile is used for soil squeezing construction, perpendicularity deviation caused by the circumferential soil quality change of the steel pipe pile is likely to happen, and the subsequent construction precision of the cement soil pile is influenced. Therefore, wedge-shaped hammer pits in central symmetry are formed in the pile cap, the pile cap acts on the wedge-shaped hammer pits in different positions of the pile cap in the piling process, the pile body is in a rotation feeding state, the wedge-shaped hammer pits in the circumferential position of the pile body are utilized for adjusting the perpendicularity of the pile body in the piling process, then the construction precision of the steel pipe pile is controlled, and therefore the construction effect of the combined foundation pile composed of the steel pipe pile and the cement soil pile is improved.
本发明涉及基桩技术领域，具体涉及一种由钢管桩和水泥土桩构成的组合基桩；包括桩体、企口榫销和桩帽；由于在桩基施工时需要考虑桩间土体刚度的参数，尽量降低其与桩体刚度的数值差异，以削弱土拱效应的情况，而其中使用钢管桩在进行挤土施工时，易受到钢管桩周向土质变化引起的垂直度偏移，影响到后续水泥土桩的施工精度；故此，本发明通过设置在桩帽上呈中心对称的楔状锤坑，在打桩过程中使桩帽作用在桩帽不同位置的楔状锤坑中，使桩体处于转动进给的状态，并利用桩体周向位置上的楔状锤坑，对打桩过程中桩体的垂直度进行调节，进而控制钢管桩的施工精度，从而提升了钢管桩和水泥土桩构成组合基桩的施工效果。
