Composite pile foundation applied to stratum containing negative friction and construction method of composite pile foundation
The composite pile foundation applied to the negative friction-containing stratum and the construction method of the composite pile foundation are characterized in that the composite pile foundation comprises a central pile body and a pile periphery filling material; the central pile body is a section or a plurality of sections of prefabricated prestressed concrete piles, and the upper section and the lower section of the central pile body are welded or mechanically connected; an isolation coating is arranged on the surface of the prefabricated prestressed concrete pile; the lower layer of the pile periphery filling material is plain concrete or a high-strength curing material and is located in the range of the non-negative friction holding layer; the upper layer of the pile periphery filling material is solidified soil and is located in the range of the negative friction-containing stratum.
一种应用于含负摩阻地层的复合桩基及其施工方法，其特征在于，所述复合桩基包括中心桩体及桩周填充材料；所述中心桩体为一节或多节预制预应力混凝土桩，中心桩体上下节之间采用焊接或机械连接；所述预制预应力混凝土桩表面设置有隔离涂层；所述桩周填充材料下层为素混凝土或高强固化材料，位于非负摩阻持力层范围；所述桩周填充材料上层为固化土，位于含负摩阻地层范围。
