CN103243711A 一种带内肋复合材料管桩 无效 - 撤回

一种带内肋复合材料管桩
摘要：
本发明公开了一种带内肋复合材料管桩，包括复合材料缠绕管和填充在复合材料缠绕管内的混凝土；所述复合材料缠绕管包括复合材料内模圆管、纵肋和纤维丝，所述复合材料内模圆管的内壁上设有纵肋，复合材料内模圆管外壁上缠绕纤维丝形成复合材料缠绕管。本发明不仅对可保护管桩、墩柱混凝土免受有害物质的侵蚀，提高混凝土的抗压强度，而且可增强复合材料管与混凝土的界面粘结强度，使得管桩和墩柱结构更具有耐久性，同时改善和提高混凝土墩柱的延性。
摘要（英）：

The invention discloses a composite pipe pile with inner ribs. The composite pipe pile comprises a composite winding pipe and concrete which is used for filling the composite winding pipe. The composite winding pipe comprises a composite internal mold round pipe, longitudinal ribs and fibers, wherein the longitudinal ribs are arranged on the inner wall of the composite internal mold round pipe, and the fibers are wound on the outer wall of the composite internal mold round pipe to form the composite winding pipe. According to the composite pipe pile with inner ribs, the pipe pile and pier stud concrete can be prevented from being corroded by harmful substances, the compressive strength of concrete can be improved, and the interfacial adhesive strength of the composite pipe and concrete can be enhanced, so that the pipe pile and pier studs are durable in structure, and the ductility of concrete pier studs can be improved simultaneously.
