Anchoring drilling rig Anchoring drilling rig is mainly used in hydropower station, railway, highway slope landslide and geological disasters prevention and treatment of dangerous rock body anchor engineering, especially for high rock slope anchorage engineering, but also for the construction of urban deep excavation, It will slightly change its floating resist the power head and foundation grouting consolidation hole, blasting hole blasting, high pressure spraying pile, tunnel Forepoling holes, etc., can be easily comprehensive construction. The main drilling methods: DTH conventional drilling, with drilling pipe, spiral drilling. Construction Practice in pore formation and the different kinds of complex drilling methods, punctured its excellent performance, the majority of the construction unit and peer recognition. The company developed a high quality and efficiency of the single-pipe, double and triple tube high voltage rotating drill pipe, drill the series have passed the test of the production site of the harsh environment, the effect of a successful construction. The company Jet rigs and accessories, complete sets of high spray equipment, high-pressure injection pump and accessories crawler rotary jet pile, high jet car Churning Pile manufacturers, double-barreled drill, drill three sets of products, professional high-pressure pipe ram service. Gravel piles have what effect? Its role is to: jet grouting pile reinforcing soft ground, to improve the bearing capacity and enhance the roadbed stability and reduce settlement and differential settlement of the foundation, has an important role. Vibration Gravel Pile, which uses vibration sinking pipe piling machine as the main equipment, is an imitation of compacted sand pile of rubble manufacturing process column. The method commonly used to fill the tube section, can be uniform method extubation extubation, extubation speed is generally not more than 1.5m / min, shrinkage-prone strata, extubation may be due to slow speed. Further double-pipe jet grouting pile driver, to avoid neck, broken pile should be appropriate to expand the pile diameter, can be anti-interpolation. It refers to the so-called anti interpolation in extubation pull Jane 0.5-1.0m then sank 0.5 a pile pipe 1.0m, ....... For pile pipe has been pulled out the ground, and the filler is less than the design value can be reused play.
