Soft Rock Tunnel horizontal jet grouting method: the completion of the pre-prepared aqueous slurry fed to the first type drilling Grouting after the end of the first type of drilling equipment, so as to exit the drill The first type of drilling and drilling along the first type form a first type of pile body from the inside out, completely out of the drill stop after the first type drilling horizontal rotary jet grouting, the note Pulp device is provided in the movable body and located between the first bracket and the second support bracket, said spray boom rotating jet device further comprises a rotating jet device comprises adjacent to the drill bit setting and can spray boom around the longitudinal axis of the nozzle, and the nozzle is connected to the rear end of the pipeline, the grouting device through the pipeline to transport the slurry nozzle performance and major fault of the jet grouting rig anchoring device Landslide Control Project and dangerous rock mass Anchoring Anchoring rig is mainly used in railway, highway, water conservancy, hydropower facilities Jet pile driver model, control buildings displacement high rock slope anchorage engineering jet grouting pile driver, but also with in urban construction of deep excavation and foundation reinforcement works holes, blasting holes and tunnels Forepoling hole blasting etc. Good performance: Compact, small size, light weight, flexible, can be applied to start work on a high slope and scaffolding; hydraulic power output torque greater level high pressure jet grouting pile, strong drilling capacity, Rig wide range of use; power head output speed is continuously variable, you can choose according to different drilling parameters and geological conditions of construction requirements, in order to achieve optimum drilling efficiency. Therefore, no matter what type of anchor rig rotary jet pile driver power, hydraulic drive system is an important part of the anchor drilling equipment, if maintained properly, 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.
