Pile repairing method for prefabricated solid pile
The invention relates to the technical field of prefabricated piles, and discloses a pile repairing method for a prefabricated solid pile, which comprises the following steps of: drilling: drilling downwards from the top of the prefabricated solid pile to a position near a defect of a pile body of the prefabricated solid pile to form a grouting hole; and grouting is conducted, specifically, high-pressure grouting equipment partially extends into the grouting holes, cementing materials are injected into the grouting holes, and the cementing materials at least fill the defect positions of the pile body of the prefabricated solid pile, so that the pile body of the prefabricated solid pile is continuous and complete in the circumferential direction. The grouting hole is drilled downwards in the top of the prefabricated solid pile to the position near the defect position of the pile body, and the cementing material is injected into the grouting hole to fill the defect position of the pile body of the prefabricated solid pile, so that the pile body of the prefabricated solid pile is continuous and complete in the circumferential direction, the purpose of pile repairing is achieved, and the bearing capacity of the pile body is improved.
本发明涉及预制桩技术领域，本发明公开一种预制实心桩的补桩方法，包括钻孔步骤：于预制实心桩顶部向下钻孔至预制实心桩桩身缺陷处附近形成注浆孔；及注浆步骤：将高压注浆设备部分伸入所述注浆孔，向所述注浆孔注入胶凝材料，胶凝材料至少填充预制实心桩桩身缺陷处，以使预制实心桩桩身周向连续完整。通过对预制实心桩顶部向下钻注浆孔至桩身缺陷处附近，向注浆孔注入胶凝材料填充预制实心桩的桩身缺陷处，使预制实心桩桩身周向连续完整，达到补桩的目的，提高桩身承载力。
