Anchoring rig performance and major fault anchor rig is mainly used for Landslide Control Project and dangerous rock mass anchoring of railway, highway, water conservancy, hydropower facilities, control buildings displacement high rock slope anchorage engineering, but also for the construction of the city Deep excavation and foundation reinforcement works holes, blasting holes and tunnels Forepoling hole blasting and the like. Good performance: Compact, small size, light weight, flexible Jet rig foundation treatment, can be applied to start work on a high slope and scaffolding; hydraulic power output torque is large, strong ability drilling rig wide range of use; power head output speed of the continuously variable transmission, can choose drilling parameters crawler rigs foundation treatment and construction requirements according to different geological conditions, in order to achieve optimum drilling efficiency. Therefore, no matter what type of anchor rig, hydraulic drive system is an important part of the anchor drilling equipment, if maintained properly walker rig foundation treatment, there will be a variety of failures, weight affect the normal operation of equipment, so it should be very pay attention to the hydraulic system maintenance. Hydraulic system failure that may occur are varied, most of the fault in the course of the oil produced is due to the inappropriate choice of oil has been contaminated, the system into the air and caused by excessive oil. [Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] High Pressure Injection Method (Jet Piles) jet grouting pile construction technology is a new development on the basis of the common chemical grouting reinforced soil The method is the use of high pressure water jet excavate rock of a technology. With a high-pressure pump (usually 15-25MPa) the cement-based or water glass slurry through a special nozzle tip drill at high speed into the soil foundation treatment spray rig, when the spray nozzle in a slurry, slowly rotating side (20r / min) , slowly lift one side (typically 15-30cm / min) high pressure slurry level jet, constantly cutting the soil, and to force the cutting down of soil and slurry mixing, and finally in the effective firing range by the ejection force to form a circular pour mixture is continuously piled into a circular cylinder.
