Cement soil occlusion mixing pile vertical shaft locking opening construction technology
The invention discloses a cement-soil occlusion mixing pile vertical shaft fore shaft construction process which comprises the following steps: S1, preparation before construction: leveling a site, removing obstacles on the ground, and preparing cement and construction tools required by construction; s2, measuring and setting out; s3, a pile machine is in place, the pile machine is installed and debugged after being transported to a construction site, the pile machine is transferred to a designated pile position after debugging is correct, a drilling rig is straightened, and it is ensured that the perpendicularity error of a pile body is not larger than 1/150; s4, preparing cement slurry, namely weighing various materials with corresponding quantity by adopting calibrated weighing and metering equipment, and mixing and stirring to prepare the cement slurry; s5, guniting is conducted, a double-spraying and double-stirring construction technology is adopted, a drill rod of a stirring machine cuts soil downwards, a slurry feeding pump sprays cement slurry to the soil body, and pouring of a single pile body is completed; s6, pile position meshing is conducted, specifically, the pile machine is moved to the next pile, it is ensured that the preset meshing distance is reached between the two piles, and the step S5 is repeated for construction till pouring of all pile bodies is completed; and S7, concrete at the top of the locking opening is excavated and poured.
本发明公开水泥土咬合搅拌桩竖井锁口施工工艺，包括如下步骤：S1，施工前准备，平整场地，清除地面障碍物，预备施工所需水泥以及施工工具；S2，测量放样；S3，桩机就位，桩机运至工地后安装调试，调试无误后转移至指定桩位，将钻架调直，确保桩身垂直度误差不大于1/150；S4，水泥浆制备，采用已标定好的称重计量设备称取相应数量的各种材料，混合搅拌制备水泥浆料；S5，喷浆，采用双喷双搅施工工艺，搅拌机钻杆向下切土，送浆泵向土体喷水泥浆，完成单个桩体浇筑；S6，桩位咬合，移动桩机至下一根桩，确保两桩之间达到预设咬合间距，重复S5进行施工，直至完成所有桩体的浇筑；S7，开挖浇筑锁口顶部混凝土。
