Prestressed cable stiffening steel-concrete combined type high pile cap foundation
The embodiment of the invention discloses a prestressed cable stiffened steel-concrete combined type high-pile bearing platform foundation. The prestressed cable stiffened steel-concrete combined type high-pile bearing platform foundation comprises bearing platform concrete; the bearing platform steel cylinder comprises a steel shell and a tower cylinder steel pipe; the tower tube steel tube is arranged above the bearing platform concrete and is connected with the bearing platform concrete; the steel shell is arranged on the outer side of the tower tube steel pipe in a sleeving mode and attached to the bearing platform concrete. The steel shell is connected with the bearing platform concrete through the prestressed cable assembly; the pile foundation is arranged below the bearing platform concrete; the first end of the pile foundation is embedded into the bearing platform concrete, and the second end of the pile foundation is embedded into the rock stratum. According to the prestressed cable stiffened steel-concrete combined type high-pile bearing platform foundation, the outer side of the tower tube steel pipe is sleeved with the steel shell, the steel shell is attached to the bearing platform concrete, the steel shell provides lateral constraint for the bearing platform concrete, meanwhile, the steel shell is connected with the bearing platform concrete through the prestressed cable assembly, and the bearing platform concrete is connected with the steel shell through the prestressed cable assembly. The problem of cracking at the joint of the bearing platform steel cylinder and the bearing platform concrete is effectively avoided, and the reliability of the bearing platform foundation is further improved.
本发明实施例公开了一种预应力索加劲钢混组合式高桩承台基础，包括：承台混凝土；承台钢筒，包括钢壳和塔筒钢管；塔筒钢管设置于承台混凝土的上方，且与承台混凝土连接；钢壳套设于塔筒钢管的外侧，且贴合于承台混凝土；钢壳通过预应力索组件与承台混凝土连接；桩基，设置于承台混凝土的下方；桩基的第一端埋入至承台混凝土内，桩基的第二端嵌入至岩层内。本发明提供的预应力索加劲钢混组合式高桩承台基础，在塔筒钢管的外侧套设钢壳，且钢壳贴合于承台混凝土，使钢壳为承台混凝土提供侧向约束，同时钢壳通过预应力索组件与承台混凝土连接，有效地避免了承台钢筒与承台混凝土连接处的开裂问题，进而提高了承台基础的可靠性。
