Applicable conditions: anti-seepage and water stop Engineering: anti-seepage treatment of foundation pit shaft, earth dam, embankment, sheet pile joint, etc. Reinforcement engineering: building settlement, soft foundation reinforcement and solidification, building pier foundation treatment, railway and highway pier reinforcement, etc. Working mode: high pressure pump + compressed air is used to inject high pressure slurry into the ground through drilling rig and drilling tools. Equipment configuration: xp-65 super elevated rotary jet drilling rig. Requirements of rotary jet drilling rig: rotational speed 0-150rpm, torque 4000-7000n · M. construction efficiency: 120-250m / shift (10 hours). Construction features: it can be constructed from one pole to the end within the height range of tower, with high construction efficiency. Points for attention in Construction: 1. Reasonable allocation of pumps and machines and tools: single, double or triple machines and tools should be selected according to the needs, and the backstage and machine should cooperate efficiently. 2. The wearing parts and sealing parts of the drilling rig shall be fully prepared. 3. For the construction of high tower, the operators should do a good job in safety training, daily maintenance of drilling tools and high-pressure pump. 4. It is necessary to do a good job in the management of return slurry and backstage materials. Rotary spraying construction requires professional and meticulous, high safety requirements of personnel, machines and tools, and high site management requirements. When it is difficult to run the rotary jet drill pipe, it must be used together with the pilot drill. It belongs to the construction of high tower, and the safety of hoisting must be paid attention to in the process of landing tower and construction. The company's rotary jet drilling rig can be modified swing jet construction.
