Post-grouting construction process for cast-in-situ bored pile
The invention relates to the technical field of cast-in-situ bored pile post-grouting construction processes, and discloses a cast-in-situ bored pile post-grouting construction process which is characterized in that a grouting side pipe is divided into a first grouting side pipe assembly and a second grouting side pipe assembly which are split, and the first grouting side pipe assembly and the second grouting side pipe assembly are fixed together through a connecting piece; the strength of the joint of the first grouting side pipe assembly and the second grouting side pipe assembly is improved, deformation or fracture of the joint is prevented, and the situation that normal grouting operation is affected due to blockage of the grouting pipe is prevented. Before the reinforcement cage is put down, the first grouting side pipe assembly is arranged on the reinforcement cage in a sleeving mode so that the first grouting side pipe assembly can move downwards along with the reinforcement cage, when the reinforcement cage moves downwards till the top of the first grouting side pipe assembly completely enters a pile hole, the first grouting side pipe assembly stops moving downwards, and the second grouting side pipe assembly is connected to the first grouting side pipe assembly. And the time required by welding is saved, the grouting efficiency is improved, and the human resource cost is reduced.
本发明钻孔灌注桩后压浆施工工艺技术领域，公开了一种钻孔灌注桩后压浆施工工艺，将注浆侧管设置为分体式的第一注浆侧管组件和第二注浆侧管组件，第一注浆侧管组件和第二注浆侧管组件通过连接件固定在一起，提高了第一注浆侧管组件和第二注浆侧管组件连接处的强度，防止连接处的变形或断裂，防止压浆管堵塞，影响正常压浆作业。钢筋笼下放前，先将第一注浆侧管组件套装于钢筋笼上使其可随钢筋笼一起下行，当钢筋笼下行至第一注浆侧管组件的顶部完全进入桩孔时停止，将第二注浆侧管组件连接于第一注浆侧管组件上，这一工艺安装快捷方便，节省了焊接所需的时间，提高了压浆效率，减少了人力资源成本。
