Grouting steel pipe reinforced pile with pile periphery extending outwards and construction method
The invention discloses a pile periphery extending grouting steel pipe reinforced pile and a construction method, the pile periphery extending grouting steel pipe reinforced pile comprises a reinforcement cage and further comprises an internal reinforcing steel plate; the corrugated pipes are mounted in the reinforcement cage through the bolt holes; after the reinforcement cage is mounted to a preset position, grouting is performed to form a pile foundation; the grouting steel pipes are arranged in the corrugated pipes; after the pile foundation is hardened, the pile foundation is rotationally pushed to a preset position through threads, a grouting connecting pipe of grouting equipment is connected, and the grouting pressure is adjusted to form a steel pipe concrete and a grouting consolidation body; the outwards-extending grouting steel pipe and the grouting consolidation body of the grouting steel pipe provide tensile resistance and pulling resistance for the pile foundation, the tensile resistance and the pulling resistance are transmitted to the pile foundation body through the grouting steel pipe, and the bearing capacity of the pile foundation is greatly enhanced; in other words, the pile periphery outward-extending grouting steel pipe reinforcing pile is different from a traditional pile foundation post-grouting technology for reinforcing the friction force between pile soil, the soil squeezing effect is used as an auxiliary effect, tensile resistance and pulling resistance are provided for the pile foundation through the outward-extending grouting steel pipe and the grouting consolidation body, and then the bearing capacity of the whole pile foundation is enhanced.
本发明公开了一种桩周外伸注浆钢管增强桩及施工方法，包括钢筋笼，还包括：内部加强钢板；多个波纹管，通过螺栓孔安装在钢筋笼内；钢筋笼安装至预设位置后，注浆形成桩基；多个注浆钢管，置于波纹管内；待桩基硬化后，通过螺纹旋转推进至预设位置后，连接注浆设备的注浆连接管，调节注浆压力形成钢管混凝土以及注浆固结体；外伸的注浆钢管及其注浆固结体为桩基提供了抗拉力与抗拔力，并通过注浆钢管传递给桩基本体，极大增强了桩基的承载力；即该桩周外伸注浆钢管增强桩与传统桩基础后注浆技术加强桩土之间的摩擦力不同，其以挤土作用为辅，通过外伸的注浆钢管以及注浆固结体为桩基提供了抗拉力与抗拔力，进而增强了整体桩基的承载力。
