Construction method of composite carrier pile and composite carrier pile thereof
The construction method of the composite carrier pile comprises the following steps that a prestressed hollow pipe pile is constructed, and the bottom of the prestressed hollow pipe pile is filled with filler; the filler is tamped to the position below the bottom of the prestressed hollow pipe pile, and the filler and a soil body below the bottom of the prestressed hollow pipe pile are confidential to form a pile end carrier with the section size larger than the outer diameter of the prestressed hollow pipe pile; the pile end carrier continues to be tamped, and a mounting hole used for containing a reinforcement cage is formed; the reinforcement cage is mounted in the mounting hole, and the reinforcement cage extends into the prestressed hollow pipe pile; concrete is poured into the mounting holes and the prestressed hollow pipe pile to the designed height; according to the prestressed hollow pipe pile, the pile end carrier is arranged at the bottom of the prestressed hollow pipe pile, and the pile body is arranged in the prestressed hollow pipe pile and extends into the pile end carrier, so that the contact area between the end part of the prestressed pipe pile and the carrier is increased, and the bearing capacity of a single pile and the pulling resistance are improved.
本发明公开了一种复合载体桩的施工方法及其复合载体桩，包括以下内容：施工预应力空心管桩，并在所述预应力空心管桩底部填入填充料；夯击所述填充料至所述预应力空心管桩底部以下并与预应力空心管桩底部以下的土体进行机密形成截面尺寸大于预应力空心管桩外径的桩端载体；继续夯击所述桩端载体并形成用于放置钢筋笼的安装孔；在所述安装孔内安装所述钢筋笼并使所述钢筋笼延伸至所述预应力空心管桩内；在所述安装孔和所述预应力空心管桩内浇注混凝土至设计高度；本发明采用在预应力空心管桩的底部设置桩端载体，并在预应力空心管桩内部设置桩体并延伸至桩端载体内部的方式，增加了预应力管桩的端部与载体的接触面积，既提高了单桩承载力又提高了抗拔力。
