Post-grouting type conical thorn pile for composite foundation and grouting device
The invention provides a post-grouting type conical thorn pile for a composite foundation and a grouting device, and relates to the technical field of foundation treatment, the post-grouting type conical thorn pile comprises a concrete pile body, a grouting hole, a sleeve with the same length as the concrete pile body, a discharging hole, a dispersing assembly, a supporting edge, a scraping ring, a lower sealing piece, an upper sealing piece, a connecting rod, a pressurizing grouting assembly, a positioning assembly and a supporting assembly; according to the device, targeted grouting can be carried out on complex geology of different heights through graded grouting, that is, different slurries can be injected into the concrete pile body at different heights, and a stable and dispersed cone thorn structure is formed by selecting different grouting pressures; the side friction resistance of the concrete pile body is greatly improved, the overall bearing capacity of the concrete pile body after a composite foundation is subsequently assembled is enhanced, the subsequent maintenance cost of the concrete pile body is low, the concrete pile body is convenient and fast to use, the adaptation effect on different soil environments is good, and the concrete pile body is suitable for batch pile sinking construction.
本发明提出了一种复合地基用后注浆式锥刺桩及注浆装置，涉及地基处理技术领域，包括混凝土桩体、注浆孔、与混凝土桩体长度相等的套管、出料孔、分散组件、支撑棱、刮料环、下密封件、上密封件、连接杆、加压注浆组件、定位组件以及支撑组件；本装置通过分级式注浆便可对不同高度的复杂地质进行针对性注浆，即混凝土桩体的不同高度可注入不同的浆体且选择不同的注浆压力已形成稳定且分散的锥刺结构，进而大幅度提高混凝土桩体的侧摩阻力进而其后续组装复合地基后的整体承载力得到增强，且混凝土桩体后续的维护成本低且便捷，应对不同土壤环境的适应效果好，适合批量沉桩施工使用。
