High-pressure jet grouting composite foundation serving as uplift pile and construction method
The invention discloses a high-pressure jet grouting composite foundation serving as an uplift pile and a construction method.The foundation comprises an anchor hole free section and an anchor hole expanded head, an anchor rod is arranged in the anchor hole free section, a steel sleeve is arranged outside the anchor rod in the anchor hole free section, and an anti-corrosion coating is arranged between the steel sleeve and the anchor rod; a corrugated pipe is arranged on the portion, outside the free section of the anchor hole, of the anchor rod, a concrete bottom plate is arranged above the corrugated pipe, and a plain soil layer is arranged between the lower portion of the concrete bottom plate and the exterior of the anchor hole. By utilizing the characteristic of high tensile strength of the steel bars, the defect that a conventional composite foundation cannot be used as an uplift pile is avoided, and the application scene of the composite foundation is expanded.
本发明公开了一种高压旋喷兼作抗拔桩的复合地基及施工方法，其中：该地基包括锚孔自由段和锚孔扩大头，在锚孔自由段内设置有锚杆，在锚孔自由段内部的锚杆的外部设置有钢套管，并在钢套管与锚杆之间设置有防腐涂层，在锚孔自由段外部的锚杆上设置有波纹管，在波纹管的上方设置有混凝土底板，并在混凝土底板的下方与锚孔外部之间设置有素土层。本发明通过利用钢筋抗拉强度高的特点，规避了常规复合地基无法作为抗拔桩的缺陷，有利于扩大复合地基使用场景。
