High-pressure jet grouting pile construction method
The invention discloses a high-pressure jet grouting pile construction method which comprises the following steps: measuring and positioning to obtain a plurality of pile positions to be subjected to hole forming; a drilling machine is used for conducting hole forming on the pile positions to be subjected to hole forming one by one, and a plurality of pile holes are formed; the construction parameters of the high-pressure spraying trolley are adjusted so that the construction parameters can meet preset conditions; cement paste is sprayed to the pile holes one by one through a spraying pipe of the high-pressure spraying trolley; and the jet pipe rotates and swings in the pile hole and gradually lifts the jet pipe to form a plurality of high-pressure jet grouting piles. According to the method, after holes are formed in a pile position to be subjected to hole forming through a drilling machine, each pile hole is cut twice through a high-pressure spraying trolley to damage soil layers, the soil layers are cut and damaged through composite spraying fluid of a high-pressure pump and compressed air for the first time, and soil bodies are cut through composite spraying fluid of high-pressure slurry and compressed air for the second time; the cutting depth is increased, the consolidation diameter is increased, and the construction quality is improved while the construction efficiency is improved.
本发明公开了一种高压旋喷桩施工方法，包括如下步骤：进行测量定位，获得多个待成孔桩位；利用钻机逐个对各所述待成孔桩位进行成孔，形成多个桩孔；调节高喷台车的施工参数，以使所述施工参数满足预设条件；利用所述高喷台车的喷管逐个对各所述桩孔喷射水泥浆；在所述桩孔中旋转摆动并逐步提升所述喷管，形成多个所述高压旋喷桩。本发明利用钻机在待成孔桩位进行成孔后，通过高喷台车对各桩孔进行两次切削破坏土层，第一次是高压泵和压缩空气的复合喷射流体切削破坏土层，紧接着的第二次是高压浆液和压缩空气的复合喷射流切削土体；增加了切削深度，加大了固结直径，提高了施工效率的同时，提高了施工质量。
