High-pressure jet grouting drilling rig self-adaptive to stratum and construction method of high-pressure jet grouting drilling rig
The invention belongs to the technical field of high-pressure jet grouting, and provides a stratum self-adaptive high-pressure jet grouting drilling machine and a construction method thereof.The stratum self-adaptive high-pressure jet grouting drilling machine comprises a sounding composite jet grouting drill bit which is fixedly connected to the bottom of a drill rod, and a monitoring unit is arranged in the sounding composite jet grouting drill bit; a plurality of gas slurry nozzles are fixedly connected to the side, close to the drill rod, of the outer wall of the sounding composite rotary spraying drill bit at equal intervals and used for enlarging the hole diameter of static pressure formed holes and spraying gas slurry in a rotary mode. The quality detection unit is arranged at the end, close to the drill rod, of the sounding composite jet grouting drill bit and used for detecting the pile diameter and the quality and effect after reinforcement; the slurry spraying and pumping control unit is communicated with the plurality of gas-slurry nozzles and is used for performing targeted control on spraying parameters of gas-slurry aiming at different soil layers; and the data acquisition system is arranged on the anchoring drilling machine. Parameters in the construction process can be intelligently adjusted according to changes of stratum properties, and the construction quality is dynamically controlled.
本发明属于高压旋喷技术领域，提供一种自适应地层的高压旋喷钻机及其施工方法,包括触探复合旋喷钻头，触探复合旋喷钻头固定连接在钻杆的底部且内部设置有监控单元，触探复合旋喷钻头的外壁靠近钻杆的一侧等间距固定连接有若干气浆液喷头，用于扩大静压成孔的孔径并旋喷气浆液；质量检测单元，质量检测单元设置在触探复合旋喷钻头靠近钻杆的一端，用于对桩径、加固后的质量与效果进行检测；喷浆泵送控制单元，喷浆泵送控制单元与若干气浆液喷头连通，用于针对不同的土层对气液浆的喷射参数进行针对性控制；数据采集系统，数据采集系统设置在锚固钻机上。本发明可以根据地层性质的变化智能调整施工过程的参数，动态控制施工质量。
