CFG pile precast pile cap reserved hole grouting construction method
The invention relates to the technical field of building construction, in particular to a CFG pile precast pile cap reserved hole grouting construction method. According to the CFG pile precast pile cap reserved hole grouting construction method, a grouting hole and a groove are reserved in a precast pile cap, after the pile head of a CFG pile is chiseled away and cleaned, the precast pile cap is hoisted to the position above the CFG pile, the groove reserved in the precast pile cap is aligned with the pile head of the CFG pile and then put down, the precast pile cap is installed in place, and after the precast pile cap is installed in place. A non-shrinkage grouting material is poured from a grouting hole reserved in the precast pile cap, the grouting material is automatically leveled by means of self weight and fills a contact surface gap between the pile head of the CFG pile and the precast pile cap and the grouting hole reserved in the precast pile cap, so that the pile head of the CFG pile and the precast pile cap can be completely combined together, and the effect of transmitting foundation stress is achieved; and compared with a cast-in-place pile cap construction method, the CFG pile precast pile cap reserved hole grouting construction method can better guarantee the engineering quality and the construction period requirement, and has the characteristics of high construction speed, relatively simple process, easiness in quality control and the like.
本公开涉及建筑施工技术领域，尤其涉及一种CFG桩预制桩帽留孔灌浆施工方法。本公开提供的CFG桩预制桩帽留孔灌浆施工方法，在预制桩帽上预留注浆孔和凹槽，在CFG桩的桩头凿除清理完毕后，将预制桩帽吊至CFG桩的上方，预制桩帽上预留的凹槽对准CFG桩的桩头后放下，将预制桩帽安装就位，预制桩帽安装就位后，将无收缩灌浆料从预制桩帽上预留的注浆孔灌入，灌浆料依靠自重自行流平并填充CFG桩的桩头与预制桩帽的接触面间隙以及预制桩帽上预留的注浆孔，以保证CFG桩的桩头与预制桩帽能完整地结合在一起，起到传递基础应力的作用；相较于现浇桩帽施工方法，更能保证工程质量，保证工期要求，具有施工速度快、工艺相对简单、质量容易控制等特点。
