Top drive impact high-pressure jet grouting pile construction technology
The invention relates to a top drive impact high-pressure jet grouting pile construction process, which belongs to the technical field of building construction, and comprises the following steps: S1, paying off and positioning: carrying out pile position measurement and placement in a reasonable field arranged in a first party according to a slope protection pile design drawing; s2, drilling machine in-place, wherein drilling machine alignment is conducted according to the measured pile position, and the integrated drilling machine is arranged at the designated position; and S3, drilling operation is conducted, specifically, the integrated drilling machine is started, and drilling is conducted while rotary spraying is conducted. S4, slurry and grouting equipment are prepared, specifically, the weight of water and cement is measured according to the designed water-cement ratio, and after the water and the cement are evenly stirred in a slurry stirring barrel, the water and the cement are filtered through a 60-mesh sieve and put into a slurry storage barrel; the slurry storage barrel is used for continuously stirring the cement slurry to prevent the cement slurry from precipitating; a pump head of the grouting pump is covered with a fine-mesh gauze cover, so that a drill nozzle is prevented from being blocked due to suction of coarse particles; and S5, after drilling reaches the designed depth, a high-pressure grouting pump is started, and slurry is jetted while the integrated drilling machine is lifted. The construction method has the effect of improving the construction efficiency.
本申请涉及一种顶驱冲击高压喷射注浆桩施工工艺，属于建筑施工的技术领域，其包括以下步骤:S1、放线定位：在甲方安排的合理场区根据护坡桩设计图纸进行桩位测放；S2、钻机就位：根据测放的桩位进行钻机对位，将一体式钻机布置在指定位置；S3、钻进作业：启动一体式钻机，一边旋喷，一边钻进。S4、制备浆液及注浆设备：按照设计水灰比对水和水泥重量进行计量，在搅浆桶里搅拌均匀后，经60目筛过滤，放入储浆桶中；储浆桶对水泥浆应进行不间断搅拌，防止水泥浆沉淀；注浆泵泵头用细目纱网罩罩住，防止吸入粗颗粒物而堵塞钻头喷嘴；S5、钻进达到设计深度后，启动高压注浆泵，边提升一体式钻机边喷射浆液。本申请具有提高施工效率的效果。
