Cast-in-place pile construction technology
The invention provides a cast-in-place pile construction technology, and relates to the technical field of building construction, and the cast-in-place pile construction technology comprises the following steps: construction preparation; measuring and setting out; embedding a pile casing; preparing clay and slurry; constructing a drilling machine platform; manufacturing a reinforcement cage; drilling construction is conducted; cleaning the hole; mounting a reinforcement cage; concrete is poured, a post-grouting pouring method is adopted, and the post-grouting pouring method at least comprises grouting pipe pre-embedding and grouting construction; hole-forming quality inspection and pile-forming quality control are conducted regularly in the steps, the perpendicularity of a drilling frame and a drilling rod is checked, the pile position, the pile top elevation and the hole-forming depth are determined, pile-forming quality inspection is conducted, and the bearing capacity, the load and the displacement condition of the pile are determined. According to the cast-in-place pile construction process provided by the invention, through data analysis of hole-forming quality inspection and pile-forming quality control and on-site investigation, the pile body can be effectively controlled and inspected, and the construction quality of the cast-in-place pile is improved.
本发明提供了一种灌注桩施工工艺，涉及建筑施工技术领域，包括以下步骤：施工准备；测量放样；埋设护筒；粘土和泥浆准备；构筑钻机平台；钢筋笼制作；钻孔施工；清孔；钢筋笼安装；灌注混凝土，采用后注浆灌注法，其中至少包括注浆管预埋和和注浆施工；在上述步骤中定期进行成孔质量检查和成桩质量控制，校核钻架及钻杆的垂直度，确定桩位、桩顶标高和成孔深度，并进行成桩质量检测，确定桩的承载力以及荷载和位移情况。本发明提供的一种灌注桩施工工艺通过成孔质量检查和成桩质量控制的数据分析以及现场的勘察，可以有效的对桩体进行控制检验，提高灌注桩的施工质量。
