Construction method of jet grouting pile for air shaft
The invention discloses a construction method of a jet grouting pile for an air shaft. The construction method includes the following steps of: step (1), on-site processing; step (2), pile positioning; step (3), equipment installation and debugging; step (4) equipment placement and centering; step (5), placement and drilling of a drilling machine; step (6), high-pressure jet spraying grouting; step (7), processing of waste slurry; step (8), washing of instruments; and step (9), movement of rotary jetting equipment to the next hole position. The invention relates to the technical field of jet grouting piles for air shafts. According to the construction method of the jet grouting piles for the air shaft, all data are alternately checked before construction to guarantee smooth proceeding of the construction; during each rotary jet grouting, grouting is performed before rotation and lifting; the water cement ratio is strictly proportioned according to requirements; enough cement slurry supply is guaranteed; construction interruption caused by material shortage is prevented; the jet grouting pile is manufactured at a time; the quality of the jet grouting pile is further guaranteed; andthe problems that the existing jet grouting pile construction method is hard to guarantee the quality of the jet grouting pike and the use efficiency is poor.
本发明公开了一种风井旋喷桩施工方法，包括以下步骤：步骤一、现场处理；步骤二、桩位定位；步骤三、设备安装和调试；步骤四、设备就位及对中；步骤五、对钻机进行就位、钻孔；步骤六、高压旋喷柱浆；步骤七、废弃浆液处理；步骤八、冲洗机具；步骤九、移动旋喷机具至下一孔位，本发明涉及风井旋喷桩技术领域。该风井旋喷桩施工方法，施工前对各项数据进行间隔检查，保障施工顺利进行，每次旋喷时，先喷浆后旋转和提升，水灰比严格按要求配比，保障足够水泥浆的供应，保障不会因用料短缺导致施工中断，旋喷柱一次制造完成，进一步保障旋喷柱的质量，解决了现有旋喷柱施工方法难以保障旋喷柱的质量，使用效率不佳的问题。
