The invention provides a pile end post-grouting steel pipe pile and a construction method thereof. The pile end post-grouting steel pipe pile comprises a steel pipe pile body, a first grouting assembly and a second grouting assembly. The interior of the steel pipe pile body is used for accommodating a first filler with a gap; the first grouting assembly is arranged at the top of the steel pipe pile body; the first grouting assembly comprises first grouting pipes and exhaust pipes, and the first grouting pipes and the exhaust pipes are arranged in the radial direction of the steel pipe pile body at intervals. The second grouting assembly is located at the bottom of the steel pipe pile body, and the pile end post-grouting steel pipe pile is configured in the mode that slurry injected from the first grouting pipe flows out of the second grouting assembly after flowing through the gap of the first filler so as to conduct grouting on the pile end of the steel pipe pile body and soil on the pile side. According to the configuration, the inner cavity of the steel pipe pile body is used as a grouting channel, and the material consumption is reduced; and meanwhile, the pile end and the pile side soil body are reinforced through pile end grouting, and the bearing efficiency of the steel pipe pile body is improved.
本发明提供一种桩端后注浆钢管桩及其施工方法，桩端后注浆钢管桩包括：钢管桩本体、第一注浆组件、第二注浆组件；钢管桩本体的内部用于容置具有空隙的第一填充物；第一注浆组件设置于钢管桩本体的顶部；第一注浆组件包括第一注浆管以及排气管，第一注浆管与排气管沿钢管桩本体的径向间隔布置；第二注浆组件位于钢管桩本体的底部，桩端后注浆钢管桩被配置为，自第一注浆管注入的浆体，流经第一填充物的空隙后从第二注浆组件流出，以向钢管桩本体的桩端和桩侧土体注浆。如此配置，利用钢管桩本体的内部空腔作为注浆通道，节省了材料用量；同时，通过桩端注浆加固桩端和桩侧土体，提高钢管桩本体的承载效率。
